[Team julio] – Prototype I: [SAFE]

 

Description of Idea:

 

  • To send an early notification notification message about the drug expiration date and prescription refills. 
  • What are 5 measurable things your product should be able to do?

                  - Send a sound alarm accompanied with a message diplayed on LED Board or LCD indicating that specific

                   medcine is about to expire or that BB medcine  needs to be refilled two week ahead of its actual expire date.

                   

                    

  • Anticipated cost: Around $195,however, this an initial estimation .
  • We are working on making our product not be bulky or of heavy weight to make accessible and user friendly , we want to make it easy to use, so it can meet its goal as a life saver.
  • So far we dont see any issues of power limitaions as we only gonna need to power Small LED display board.
  • so far there are no safety concerns .
  • Our product is anticipated to have a very small error margins as its function is life saving.

 

Market Consideration:

This product can be of great benifit to almost any person on life long medications. we are working on finding a consumer other than CPRF clients.

Description of Prototype:

 Our intitial idea is :                                 

1.input device hand held scanner                                 

2.arduino board with usb port                                 

3. Storage device                                 

4. Ouput device could be an LCD or LED display monitor                            

How it could work :  A   client scan his prescription slip bar code, information proccessed by arduino and then be stored in the storage device( hard disk connected via usb to the arduino board.  C program codes needs to be created, to manage the saved information ( well i should say data in this case ) , Coding will be based  COUNTERs and which will count off number of days since you scanned your Prescription and display a message i.e” You will be out of your BB medication in 10 days”                                       

example:   

#include<stdio.h>     

int main();      i: 30 ;      

{     

count: i+1;     

if (i,i+1; 20)     

printf(” Your Rx is running out in 10 days”);

}

                                                                                                                                  

now this is not the kind of coding that  will handle our work, however, this is a basic C program instructions  that i  can barely retrieve (its been along long time since i took this class), i am not saying i can write this program by my self,but , my group mate and i are working hard on this .  This supposed CODES are to be burned into the Microcontroller , in our case its Arduino which seems  to be way sophsticated to my baby steps, i mean the burning of codes as i remember, was performed   on Basic types of 8051 microprocessors. having said that, doesnt mean that arduino is a big challenge , however , we need some little time to get familiar wit it.

“MAR” – Prototype I: Wireless GPS Tracker

 

Description of Idea:

  • This device helps a person with disabilities to inform somebody in case of an emergency.
  • Wireless signal transfer, voice recording and voice transfer, power saving, weather resistant, managing multiple users
  • $200
  • A small device will be designed to wear around the neck or wrist to pass the wireless signal. An application will be designed to get input signals and track multiple users as needed.
  • Very limited power is needed only in case of an emergency and built in batteris will be used for that.
  • Not aware of any safety concerns.
  • The product is completely independent from the main wheeel chair functionality. This device is small enough for user to easily use as needed, and very easy to operate without any extra knowladge and training.

Market Consideration:

This product is mainly targeted on people with disabilities. One of the most significant barriers people with disabilites face today is to ensure their safety when they are travelling long distance alone. Most of the them do not have a successful way of informing somebody if they are faced to an emergency. The wireless signal transfer system makes this device very convenient to use even when the consumer is happen to be somewhat away from their wheel chair. Adding a limited time emergency voice recording system allows the consumer to send a short message to the receiver so that the receiver gets a better understanding of what kind of an emergency the consumer has faced on, and what kind of help needs to be sent. To build this kind of an emergency tracking system was requested by one of the disable residents at CPRF. Developing that small idea we are working on this project and it will hit the market as  it is very advantageous among disable community.

Description of Prototype:

  • A GPS tracker is attached to the wheel chair, which has the ability to track the GPS coordinated to the current location of the consumer is in.
  • A small wireless device is attached to the consumer’s wrist band or neckless.
  • In case of an emergency the consumer press a button of the small device attached to their wrist band or neckless.
  • When consumer press the button the consumer gets an oppertunity to record a small voice recording for about 20 seconds.
  • With the consumer pressing the button, a radio signal is passed to the GPS tracker attached to the wheel chair.
  • A message will be sent to the receiver’s cell phone with GPS cordinates of where the consumer is in, along with his short voice recording.
  • An application will be designed to take the input from the phone message, reads GPS coorinates and will show the address and map of the particular place.
  • This application is also able to track a unique number of the particular GPS tracker, so that if there are more than one consumers using this devices then it will know from whom the message coming from.

S.R.P.R – Prototype I: Dual Mode Table

 

Description of Idea:   

Our product is a movable and rotatable electrical table for the  C.P.R.F residents .
Functionality:

  • This product is attached to the wheelchair of the C.P.R.F residents.
  • It will have dual functionality where it can be used as a table for electronic devices (laptop and ipad) and also can be used as a food table.
  • This product will rotate 180 degree for food table and ipad/laptop. And also, will stand vertically so that it can be use as a reading table.
  • It will have extendable arms that can be controlled by the button.
  • It will also have straps to hold the electronic devices while it is being used as a food table.
  • It will be integrated with USB ports for charging the devices.


Market Consideration:

This product would be designed to help disabled people in wheelchairs. It would be a form robotic arm, but with a tray set. The C.P.R.F clients informed us of how difficult it is to set up a manual tray in front of their wheelchair since they have no good motor-function with their hands. They have a great need for a fully automated device that would alleviate that pain of setting up and removing a tray.

Description of Prototype:

  • The project will have a wooden table.
  • A power button on the side by the joy stick to fold and unfold the table which will be controlled by Arduino.
  • An electric powered extendable pole on the side of the wheelchair, that will hold and move the tray.
  • Two straps that will hold an object on the table without having to move the object when turning the tray 180 degrees. the straps will be made of  strong sticking materials, and very easy to use, and no effort will be needed .

Team Green Wu – Prototype I: Bicycle-powered Generator


Description of Idea:

  • To generate electricity to be stored or used for modular attachments
  • To be able to measure torque, power, statistics, energy generated and energy consumed
  • $200
  • It needs to be small enough to not impair the ability of the bicycle
  • The device will generate power with the aid of the person using the bicycle. It is therefore self-powered.
  • There are some safety concerns pertaining to electricity and power storage. It could be dangerous if the device does not effectively consume and release power.
  • The product needs to be reliable enough to power an external device through a USB connection.

Market Consideration:

The primary client in the CPRF patient. A secondary market will be determined as modular attachments are developed.

 

Description of Prototype:

Our prototype will be able to sense the revolutions per minute of the bicycle wheels and it will then output this speed to an LCD display. Our prototype will then convert the energy produced by the wheel and will store it in a battery. We are not entirely sure about the implementation for storing the energy obtained from the bicycle wheel. From the battery, we will then allow a USB connection to draw power from the battery and power a small USB device such as a cell phone or mp3 player.

  • As a part of this project, we will be collaborating with a CPRF client who always wanted to ride a bicycle, but never could because of her disability. We will design a prototype of a hand-pedaled stationary bike connected to a generator that will power an LCD display. 
  • This LCD display will utilize an Argueno microcontroller to control output of statistics to the display. 
  • We will builld a stationary exercise stand for our CPRF client to test on and provide data which could be used to determine the feasability of a hand-pelled, street safe bicycle for our client.
  • In further stages of prototype development we will build modular attachements, which by utilizing the power produced/stored by our stationary exercise system, will extend the usability of the initial design.

[Team Glen] – Prototype I: [Smart Mailbox]

Description of Idea:

Our smart mailbox , will avoid trips to the mail box at time no mails are not present in it.  

This smart mailbox, once completed should notify owners:

- When they get new mail

- When their outgoing mail have been picked up.

- It will be energy efficient:

                               * since the solar power harvested will recharge the main battery

                               * it will go into sleep mode at times and dates mail will obviously not delivered

 

Market Consideration:

The main consumers targeted by this product are senior citizens, people in rural areas as well as anybody else who don’t enjoy coming back empty hand after checking his or her mailbox. This smart mailbox system is only for the houses that have individual mailboxes like rural areas or homes and not for mailboxes stacked together like in apartments. The people in rural areas and senior citizens will really appreciate this product mainly because they only have to go and check their mailbox when the light is on and the mail is in the mailbox. This product will also be useful during winter and whenever it is raining. And lastly, they won’t have to struggle with the opening their mailboxes with keys anymore. Waving, their card in front of the box will release the mailbox door. 

For Glen, mom and grandmother who are already committed customers for this product, this is a low cost solution in a way that owners don’t need to have a cell phone to use it. There will be no need to turn on their computer to check their email for a notification of delivered mail. They just need once in a while to check the red LEDs on the receiver inside their house.

 

Description of Prototype:

Prototype I design is to have a working model of the mailbox sensors (infrared LED and receiver) and have sensors working flawlessly.

  • The prototype will be a wooden box with 4-6 infrared LEDs on the bottom of box and receivers on the top of the box.
  • A switch on the side of box will model the flag up and flag down
  • Flag up = green LED (with mail in box)
  • Flag down = red LED (with mail in box)
  • Flag up/down with no mail in box = no LED lights
  • All controlled with the Arduino microprocessor
  • Programming for the senors working flawlessly with Arduin0
