hear me, girls?

Yes.

Hello.

Hi.

Hello. Can you

hear me?

Okay. Can you

hear me?

Yes.

Okay. Can you

hear me?

Yes.

Yes.

I'm going to send him the link.

Yes, I sent it to my dad to see if he

connects right now.

Okay, okay, okay.

Ch

can be recorded, in my opinion. Yes, no, it's

not that you can't record.

Don't we have a presentation?

No.

Hey,

come on. When Isa did that, we

took a screenshot because it had to be

on the document.

Yes, yes, yes. Okay,

but let me know when, when the eyes,

at what point in the dialogue.

Uh, I'm going to, I

mean,

I'm going to present and I'm going to speak. Uh-huh.

I'm going to talk a little bit about the product

and then I'll say, "Oh, no, well, the

interview will take this many minutes.

This is our initial prototype, and that's it. It's

my turn here, and if

6 or 6 or

questions,

that's 10, right? Uh-huh

, there, we've

divided them up, right?

Okay.

Hello, can

you hear us? Hello,

good morning or afternoon. Hello, good

afternoon. Nice to meet you.

We're still missing the engineer, right?

Yes.

Well, I already sent it to him, but he hasn't

answered me.

Well, if you want, we can start now, and once he's

joined, you can tell him a little bit about the

project, right?

Mm, no, just a little.

Um, how long is the video call,

how long does it take? An hour.

Like half an hour, right?

Half,

half 40 minutes. I

think 5 minutes, right? Uh-huh

. 5 minutes. And if not, well, we'll start

with your dad, and then we'll do it

again, okay?

Okay Okay, Ji, whenever you're ready to start.

Okay, okay. Right now.

Hello, good afternoon.

Good afternoon.

Good afternoon.

Well, we're here now. I think

everyone can hear me okay, right?

Yes, they can hear you. Perfect. Um, well,

good morning, engineers José Veterán and

Miguel Espinosa. Um, we're

students from EBC and we want to

present our project, since we

want to win the competition for

these projects so we can go to the

intercamping event. The intercamping event, well,

obviously, is just because we

won the school project and it

competes with other projects from

other fields. Um, well, our

project is mainly focused on

a security collar,

primarily focused on women,

to provide them with greater security

by adding,

or rather, we plan to add an

emergency button. It will have an

integrated camera and GPS;

we're connecting it there. My partner, I'll

show you a little better in a moment. My

partner is... Presenting

the prototype we printed. It's going to be

like a little flower, and in the middle it will

have

a small camera, and we're connecting it

through an application that my

team and I created. And now let me see if I

can show you the screen so

you can see the application we made.

Um, I do

n't know if... Let's see,

there you go.

Okay. Well, we're

thinking about this application,

which will obviously be

connected to the collar. It will

tell us, obviously, the

battery percentage of the collar, our route.

Here in the application,

we also have a kind of

emergency button. It's equipped with a

camera, has audio, and location.

Here, any recent alert

that we, I don't know, accidentally

pressed, will send the

alert to us or to the contacts we have

registered. Here we'll also

have the history. We

have the most

critical alerts or warnings we've had,

right? Like, maybe it

disconnected, The battery. Here we'll be

able to have our

emergency contacts with email, location,

alerts, everything. That is, they'll go to those

contacts, they'll send them our

location, and here in the settings, we'll

also have the

device ID, and its

general characteristics. It will

indicate the safe zone, low battery,

sudden movements,

forced disconnection.

We'll be able to create a profile. And I

think I have a question.

Sure.

You mentioned that your necklace will have a

built-in camera.

When an emergency alert is triggered

, does the camera activate

automatically, or how is it

programmed? No, this camera

is recording 24/7,

precisely for any

case, even if it's not an

emergency, like someone

trying to kidnap us, but maybe, I do

n't know, someone trying to rob us,

assault us, that camera will

be active. We're

thinking about the camera

using the Use as little battery as possible, but still

record for any

eventuality, right? And also keep the audio

active so we can

see anything. And, uh-huh, tell me, Johana.

Yes, well, we also interviewed

several girls because

we already did an interview in our segment,

and several girls

told us they'd like it to

only record when they feel they're in a

risk zone, and that would be

the moment they touch the collar.

Because our prototype is supposed to

have a button here on the neck

that, when you feel you're

in a risk zone, would start recording

and send an alert.

Yes, mainly because of what

you were saying, Jess,

the camera consumes energy, and if

you have it active all the time, the

battery won't last long. So, I

think they should

program it so that it's for

emergencies, or as

Johana says,

when they feel threatened, they can

activate it manually, or in some cases, it can be

activated

by the sensors it has.

They place it, but I don't know if it

can measure the person's pulse. So that

when the heart rate increases or

something, it activates, that

could also be another option.

Uh, yes, I had just omitted a part in the

back. I can't find the

photo right now. Right now, ladies, if you could

help me find the photo we have of the

prototype to show it. This, in the back, I

mean, it's a normal necklace, like

a regular necklace we

wear. And in the back, it has a little box

that will house the

sensors and all the

technology. So, what we want

to add to that box is precisely

the emergency button, which I

think we were going to

put in a way that, after three taps, would

activate the camera or make it

more alert and send a

notification. Let me show you the

screen.

There you can see my screen.

Yes, you can see it.

Well, that's the prototype we

have. It's designed, precisely, like a

flower. The little camera will go here in the middle

, but we put it there just

to make it a bit more

discreet. This is the

back part, where the

touch controls will be. So,

we'll be able to

press it, I don't know, three times. We're

still working out that part

. And this will be

connected to the app, and since it will

have a GPS chip

and all that, this is the little thing

that will go on the back, and you

press it for three seconds to send an

immediate alert. We were

checking the prototype, something like that,

to make sure the camera was roughly this size,

and we're

getting all the measurements right so it

looks a bit

better

. Okay

,

now, give me a second.

I'd like to ask you both a few questions

before we get started with

your points of view. For your consideration

, technically, we've

already presented everything.

If you have any questions, let us know. Do you

consider it technically feasible

to develop a smart collar with an

emergency button, a discreet camera,

GPS, and a connection to a mobile phone? Do

you think it's

viable, or that it can actually be

produced?

Yes, but I see several details

there, especially regarding the

size of the collar and the

power supply.

That's going to be complicated. At

least with the cameras; there are many

spy cameras of that size, more or less, but

the battery life is only two to four

hours of

continuous recording, right? Perhaps it would be

better to record by motion, or by

some event, or that you activate it with a

gesture or a voice command. That

could work too. I

think that would be the important thing,

but what I see as the biggest issue is

the battery. And how are you going to

communicate with the

camera on the back? Not with a tablet or anything, or how will

the communication work? In that sense, or how they

had it planned.

Uh, precisely, uh, as Joa said, uh,

the back part, uh, when

you press it for 3 seconds,

the camera will activate because, well, obviously, we're going

to program it to be like an

emergency feature. It stays on for 3 seconds, and then

the camera and audio are activated

so it starts recording

anything. That will send an alert to

our emergency contacts, and they'll let

us know that everything is okay,

everything is fine, and then if they see that it's not.

Sorry, Jess. I think Miguel

is referring to the fact that in the model presented

in the image, you can't see, I mean, the

connection or communication between the

back button and the camera button is

a chain, I mean, it should have

some kind of cable. So,

yes? Or will it be

independent communication, sorry, the second one. Uh-huh

. Um, how are you going to do it? I mean, there

will be two power sources.

The camera will have its own power source, and the

wireless communication will be with the

device. Is it going to be wired or on the back? I

think it's more complicated for the

camera's battery to last if it's

wireless, right? It has to have a

wireless module. The power consumption,

because of the size, I feel like it's going to

complicate things a bit more. It's easier to have it wired

because of the size I see. I don't know

the dimensions of the device they have

on the back, but there could be

a higher-capacity battery

in that space. Maybe, I mean, I don't know

the dimensions, right? Cameras are

very small, some are 5mm, right?

But obviously what takes up space is

the size of the battery, and obviously

if the communication is wireless, then you're

also going to have to rely on a

wireless mode, and that also consumes

energy.

So, I don't know how

you have it planned.

Okay. Okay. I understand now. Well,

yes, we had it planned

precisely as wireless, but

yes, that's precisely a detail we

still need to refine because,

obviously, if we want the camera or

the sound to be, well, aware

of our

touch, Or so, well, yes,

the battery will run down. So, I think that's

a point we need to check,

ladies, if you could help me write it down, okay? And

if not, well, we'll have to create

some kind of prototype, maybe a

slightly thicker chain or something

like that, so it's not wireless, but

wired, and that way the

back can have, I don't know, a

battery, so

the system can have a

spare battery, right? For

emergencies.

Um, I don't know if you have any other comments

on this question.

Yes, that's all. The

best thing, from my point of view, is

that it should be connected by

a cable from point A to the digital unit. This is because of

the energy consumption, as

Miguel mentioned. But anyway, go ahead.

Okay. Okay. Thank you. Um, let me read you

the other question.

Um, what electronic components would be

essential to manufacture a first

functional prototype? I mean, what do

you think is viable right now, what would be

best for us? It's advisable. I don't know, to say,

"Oh, no, well I suggest you use such and such a

component or connect it in such and such a

way so that you can see that you can

be a viable prototype, that is, that it actually

works."

Cameras, you could maybe start with

some kind of camera that you can get

on AliExpress or Alibaba. They're

spy cameras, the smallest ones you'll

find. They are very, very

small modules and they require

very little power consumption. Obviously, from what I

see, you require a 1080 Full

HD camera, so the larger the

camera, the greater the power

consumption and the size of the lens.

So you'd have to check

the dimensions of your pendant, and they usually come in larger sizes

. I do

n't know if you've seen the cameras in

solariums, they're very small, aren't they?

So it can be adapted, and it would involve

searching for something that already exists and

complements what you already

have in terms of space, right? Uh, the

back part, well, you'd have to carry a

microcontroller, which is what would be in

charge of communicating with your... it's going to be

with the application, from what I see,

right? So, you need the

microcontroller, you would need the

power part, which is the battery part

, the camera, the wiring. Uh, for a

prototype, I would recommend that you

start with some kind of

microcontroller, either an Arduino or

this one, there are some called EP32,

which are like, you can connect it

to your computer and you can do these

tests with communication, right?

Whether it's Bluetooth, WiFi, this or wired,

right? So this is a

tiny little tablet, right? It's about 3 by 5

cm more or less. Obviously, it

might work well for a prototype.

Later, when you want to

move on to a real project, you

can make the PCB, which is the

logic board, with everything you

want to integrate, right? There you would have to

put the controller, uh the

power part, uh the wifi antenna, and uh the

charger. Hm. What else could I tell you

there? So, if you're going to include, for

example, I saw that you have the communication part

with these messages, then if the

device is going to have GPS, well,

obviously it's another module, right? Then

you'd have to see the

space fairly well, because what I see is

small, isn't it? The space you have, I don't

know, the dimensions of the back

of the device, but, well, the

more components you add,

for example, GPS, WiFi, all that, it will

consume more energy, so the

size of the battery will increase.

So, you would have to see

what would be ideal so that it's

not heavy or uncomfortable in the

back, right? And obviously,

for women with short hair,

the device is going to be visible, right? I don't know how

advisable it is to have it in the back

too, I don't know. Hey, do you want the

touch part? As for the touch functionality, I'm

not sure if it will be in a single

point; you'd have to add

some kind of button, or if it will simply

be sensitive to some kind of

material when you touch it and it will

respond, right? So all that

integration does require several

things, right? I mean, the main thing would be your

controller, uh, the part where you're going to

put sensors, usually the

Arduino and the other device called

EP22, which is a small controller,

already allows you to do many

integrations, that is, it already has

integration with WiFi, Bluetooth, GPS,

NFC, for example. So, this and the

battery, well, I don't know if you've seen the

old phones, they had a

tiny, small battery, it

can be integrated very well into

small spaces, and the truth is, that's why what

Professor José mentioned is a good idea, to integrate it with a

cable to the camera so that it lasts

longer.

So, uh, you could start from that

side. I think it could be a search; I've

seen some designs that are already on the

internet, but most are

local. It only has the

camera part with a microSD card and records locally,

right? It's very much just here, it doesn't have

any app controls or anything,

right? So, I mean, we'd also have to

look at the application's features there

, I don't know what else they might

want to implement. Sometimes the more

things you have, the more complicated it is in an

emergency, right? So sometimes the

easiest thing is a shout or some

voice command. Sometimes, I don't know, if it's for some

kind of emergency, well maybe

some keyword that activates you by

audio, it has to have a microphone and

obviously this one might not have a speaker,

right? But this thing has to detect

that part, right? I don't know how you plan to

integrate it, do you?

Okay. Okay. Thank you. Yes, we had already

heard about it, well, I had already seen that

part of the components, but

anyway I'm going to take it into account

for the prototype. Oh,

thank you very much.

Hey,

buddy, hey, any other advice or

design ideas? I don't know,

no, I definitely agree with

Miguel. Ultimately, the more

applications or functions you want to

add to your prototype, the more

space you'll need in the

pendant area or on the back.

So, uh, as such,

aesthetically, on the front of the

IG, well, I think it's just the

camera and some connectors, and on the

back, the development of all the

components. However, well, they do need to

review that point of

what the

necessary applications or components are

to make that part less robust. That's all

my comment.

Okay. Okay. Thank you both very much. Well,

yes, we're going to take into account

the components, because the more you

add, the more battery power it will obviously

use or the more space it will take up

. Something that can be

done to make it more convenient, so it doesn't weigh too

much, but okay. Hey girls, I don't know what

questions come next. Okay. Okay,

we have another question regarding

the cameras you

mentioned earlier, but I

wanted to ask again because I don't know

if you have any cameras you

could recommend. We

have looked for spy cameras,

but they are all quite large; they don't have

the small size

we're looking for. So, I don't know if

you guys have any recommendations,

any cameras.

I would recommend the easiest option, the type

of camera that

cell phones use, it's a pin type. They are the

smallest ones there are. There are smaller ones, but

obviously they're more

delicate, right? And I also don't know how

you plan to protect it if there's

water, if there's sweat, because all of that is going to

affect the electronics. So they

have to make sure it's waterproof,

that it meets some standard for that.

And I'm telling you, the most recommended ones are the ones

that handle cell phones. Uh, if it's

for prototypes, I'll tell you, there are many that

sell them, I could give you some

models, this one, uh, to make these

basic electronics designs. Then you

can use those. They are very

small, I tell you they are the biggest

I have ever seen, uh, 5 mm.

And obviously the complicated part is the

wiring, because the wiring is a

flexible, very thin cable. So

that flexible cable has to go to the

power module and from there to your

battery. If you're going to do

wired communication, well obviously, I don't know if you

've seen the cables, there are some

very small flat cables.

You have to try to

integrate that cable onto the collar if you're going

to send it backwards. Otherwise, the

collar would have to be bigger here

in order to have the power source

behind the camera. So, that's going to

be more weight, it's going to be more

complicated. Oh,

and if it's wireless, then it's even more

complicated because it already includes the

communication module. So,

I see it as a bit more complicated from that

perspective. I think it would be better to rewire everything

backwards and leave it all behind here. And the

cameras, I tell you, are tiny. I don't know if

you have the dimensions,

pin size. Yes, yes. This one

in the prototype they already know it or they don't

have it.

No, I don't think we've checked that part,

but we did need a camera. We started

researching and couldn't

find one that was kind of

small, but it had really bad

reviews, so we don't

know where to buy them or on what website

. We would

more or less adapt to the

size of the camera.

Yes, it would be better because especially

if they're going to sell it, well, for

production purposes I think it's more convenient for them

if it's already done, right? Not because of the

costs.

Okay.

Definitely. And just as a

comment, as Miguel also says

, the best thing to do is to

only put the camera

and everything necessary for it to work in the pendant part and

wire everything to the back.

Okay, thank you very much. This,

and another question we have would be, what

technology would you recommend to achieve a

fast and stable connection between the

collar and the mobile application?

[snort]

If you want to save battery and stability,

Bluetooth would be the way to go. There is a Bluetooth

called Bluetooth of this type,

but it is low power consumption.

So, since you're always going to have it

on and you're going to be communicating

with your cell phone, you need it to have the

minimum consumption. So, the

easiest way is Bluetooth. Well, the next step

would probably be a Wi-Fi connection, but

that requires more energy.

So, I wouldn't recommend it. And

besides,

the controller is always

searching. You would have to

program it so that it only happens when

you make some kind of gesture, right?

Whether it's the three-tap as they say,

or some voice command to send the

communication to the phone. There,

too, you depend a lot on your

phone having battery, right? So

if this one doesn't have a battery, then you're going to

have a problem, right? You would need to

have some other form of communication

if it's an emergency, wouldn't you? So,

if you want to integrate it

directly onto the module of the

little box, then that module would have to

have something else, which would be a module for

communication via

message, like a small cell phone

with an integrated cell phone chip,

and send messages, that is, have

both options, right? Send the call to the

regular cell phone and the other one as an

emergency line, right? In case your

cell phone isn't working, you don't have a battery, or you

don't have communication, right? Because that's bound

to happen, right? So,

I think it would be like this, and I think it's the

most advisable of those two options, or

rather those three, whether it's through

SMS communication with a chip

integrated into the module, Bluetooth,

or Wi-Fi, right? But I'm telling you, the

best one, I think it's going to be the best

Bluetooth if you only want it with your

cell phone, if you don't care about

external communication with something

else independent of the

cell phone, then maybe with

that messaging module, and they're

very small too. I mean, there are

many modules that can be integrated with

what I already mentioned to be able to

send a message, right? Whether it's an

emergency call to your contacts or those

saved on the chip, if

possible.

Okay. Any other comments? This

dad of Jessie,

not this one, I agree on that

point. I believe that the

collar device they are

planning should be just an

accessory, and the entire

application development should control it, simply connecting the

device to the

cell phone via Bluetooth. Um, in case they want to

make it independent, well, it's

going to make the

back of their collar even more robust, and I don't think it would be

very feasible or comfortable for anyone to

carry that on their back.

Okay. Okay. Uh, we just made

some prototypes, since they told us

that it shouldn't all be

wireless. Uh, let me introduce them to you

and then you can tell me more or less

.

Well, I think these are the ones.

Well, I don't know what's up with this one, but I think it's a bit different

from the image, but it

could be, uh, I don't know, maybe a

little more robust

, what's it called? The little chain so that it

can carry a

little bit of wiring and everything

is already connected directly, so there's no

need for everything to be

Bluetooth or something like that, it could be a

little more discreet, but it's also

a little smaller, like a little

band or necklace, you know

? Or it could be good, something like that, right?

Well, it gave us this, it gave us the

images, the artificial intelligence, which

could be a little more discreet so that it doesn't

look too

robust, too rough, so to

speak.

And

I think it suits them better this way if it's

for the collar; they can hide

the cable well at this size.

I have a question.

Uh, I found Mr. Josué's idea very interesting

, which was to

activate the sensor through

heartbeats. So, for that, what

kind of sensor would the

collar need to use? And how could the

system differentiate between an emotion, like from

exercising,

or from a risky situation? I do

n't know if you've seen

smartwatches, they have a sensor on the back

that measures heart rate. It would be

the same type. Also, I wouldn't

recommend it, maybe not so much in the

back. I mean, I don't know how the

body's physiology works, do I? But perhaps the

best thing to do would be to take it

in this part of the neck where

the veins are, where they take your

pulse, right? I don't know

if it can be integrated on this part.

They are somewhat large sensors, so

movement also affects them. I would

n't see it as very feasible that way, would I?

This, uh,

maybe on the chest, on the

back of the collar, maybe so, right?

Those types of centers affect them; the

light affects them. So when they're regular, they

also have to be close to the body.

So, it depends on the technology they

use, but there are many that

send a beam of light and

detect vibrations, and based on that,

the sensor sends you the information

. Uh, obviously, if

there's an alert, you would have to

program the application to send an alert

if the heart rate, according to

what the sensor sends you, is higher than a

certain rate,

right? Uh, but I do see the sensor thing as a bit complicated

, I mean, no, unless

you had it in your hand it would be easier,

right?

Yes,

sorry Miguel, there's also what

could be done, uh, I'm still thinking about

marketing and all that, uh, well, it could be an

accessory, a ring that

gives that signal

and is connected to the app

and the necklace. So, if it had

an extra function with an

extra accessory, then it could be, and the

original version could only be

activated by the button as they had been

handling it.

And it's possible to connect it via

Bluetooth so that it's compatible

with the application.

Yes, in the case of the ring it's

easier. Uh, well, uh, I mean, if there are

prototypes, there are rings that are already being

sold, there are some from Samsung, there are some models

from Samsung and Apple, I don't remember if they

released any, I don't remember well, but I

have seen some prototypes. I also

think you can integrate this with

your existing system; the communication is

always Bluetooth, so this is

Bluetooth Low Energy. I'll

give you the name again if you want, just so

you have it there as a

prototype. This

is easier. Yes, because I'm telling you that

if you hand it in at the school it's

moving around, so it has to be somewhere

fixed and in some place where you can take a

good census.

Okay, thank you very much.

Um, well,

um, what would be the approximate cost of

developing the first

functional prototype and how long would it take?

No,

I think it would depend a lot on what they

want to add to the final

prototype. I don't know, I mean, if they're

adding more things, obviously it's going to be

more expensive and it's going to take longer.

So, I would advise them to start

looking first.

Well, let's say just the camera with the

camera and the app,

I think it would be easier, I mean, just

the camera with the app is

easier. In fact, uh, if in this part

here, uh, I mean here, for example, the

part with more messages, well, there are

cameras that are already wireless, wifi,

very small, and the communication is either

wifi or Bluetooth, it can be both. In

this case, Wi-Fi would be better

for the signal,

and they send the alert directly to your cell phone

, right? In other words, it doesn't depend on anything other

than the technology

that your cell phone already has integrated. This,

obviously, is just the

battery. You'd need a battery,

obviously maybe hidden behind the

camera or on the collar itself, if

they didn't want it to have the back part,

that would be the quickest way, right?

Because you already have the cell phone, the camera

with the battery, and there's already

a platform, let's say, some

camera models already have

the libraries or APIs that make the

camera communicate with the

platform you want to integrate into your

cell phone. or you can unlocate your

camera in the application. Obviously, I

had to know some

programming skills in the application to be able to

communicate it, right? But this one

isn't so complicated, is it? You

can do several things with it, right?

So if you already have the communication and

camera modules, it's easy to

integrate it into the platform, which I see

already has a good design for its

application, right? He already has a more or less

general idea. So it's like the

part of the development that's already visual.

Then, it would just be the part

of adding the

programming part.

I think

the most expensive part of your project is

integrating the

small ones, there are between 3 and 6 more or

less, depending, right? Plus the battery, I don't

know, there so they don't keep adding up.

This and also if you get the

back part, well the microcontroller I

mentioned for the prototype costs around

700 or 800 pesos more or less.

with all the modules you

want. If it's just the basic

micro-temperaturer and you keep adding

things, it's cheaper, starting at

200 pesos, but if you keep adding a

battery, WiFi module, GPS and all the

other sensors, then obviously

the cost will increase. So you need to

clearly define what will

or won't go ahead and then start

budgeting for that.

Yes. And the most, I think the

most time-consuming thing would be if you order it

from China, because that affects

delivery times, right? Most

things can be obtained there. Here in

Mexico, in the city, you can find

some things, but it will definitely be

more expensive. Maybe it will work for the prototype

.

Okay. Well, to

conclude, the most advisable thing would be to

create a prototype of the simple necklace

with the camera and connect it to the

application, and then in a premium version, you

could create the ring, which would be

the one that sends the

alert sensor.

OK.

And it

could be the prototype, the

water-resistant one, because that's also a

question we have, in case it

rains or something, so that it really

has functionality

in all kinds of situations. Do

you think the camera is waterproof, or

what type of camera would you need to

buy to be waterproof?

Those of that size have no

protection. You would have to

look into how to protect it

directly;

otherwise, I don't think it's bigger

than the component.

Yes, I'll have to find a way to

protect it, and there are rules

you would have to follow to

protect that part, right? This one with the

camera and the wiring, right?

Okay. Okay.

Well, I think those were pretty much

all our questions

about the prototype. Well, we'll

carefully analyze all the

advice,

ideas, and components you gave us

to take them into account in our

prototype. We thank you both for

taking the time to

listen to us and give us your advice. And

anyway, if possible, and if at any

point we don't have any other doubts, if

possible, we would appreciate it if you could help us with any further

questions or doubts. Okay, well, that's it.

Yeah.
