Team Alpha – Prototype I Proposal: The Smart Mailbox

Description of Idea:

  • Function: To sense automatically when there is a new mail in a mailbox and remotely notify the mailbox owner.
  • 5 measurablethings the Smart Mailbox should achieve:

    a- Send radio signal where there is a new mail in the box.

    b- Has 2 units, one in the mailbox, the second in the house of user.

    c-Send a message to smart phone through txt message or through app.

    d- Should have low profile.

    e- Should last at least 6 months without maintenance.

  • Anticipated cost: Below $25
  • The unit in the mailbox should be less than 5×4 inches. And less than 200 grams in weight.
  • The unit in the mailbox should use one small watch battery, the unit in the house can work on the grid or battery.
  • All units should have no sharp edges to make sure it does not hurt user while installing the units.
  • The product should be reliable to resist rain and wind and medium shakes.
  • There should be a clear manual about installing the product and also maintaining it.

Market Consideration:

  • Target costumer: Average  home owner age 18-50.
  • Miss. Jessica Bever:  She thinks it’s a good idea for a home owner
    specially those who love technical gadgets. But it should not exceed the
    standard price for As Seen on TV of  $19.99
  • Mr.Sam Herman “wichita”:  He thinks it should have more features like
    give information about weather outside and temperature.

Description of Prototype:

A prototype should perform this measurable task and pass the test successfully
in a real mailbox:

  • It should detect a new mail in the mailbox and give a visible sign.
  • It should perform 10 tests and pass at least 9 successfully.

Team DSSP – Prototype I Proposal: Smart MailBox For Smart Wheelchair

Description of idea:

Smart Mail Box for smart wheelchair is a smart device to send notifications for receiving mails in mailbox to the wheelchair users or every other appropriate users. As soon as the smart mail box senses the mails landed inside it, it will notify the user via sms(email) and/or LCD display connected to the wheelchair. The control panel will be displayed in the LCD display of Wheelchair, so the user in wheelchair will be able to monitor mails in mailbox. Also, the wheelchair user will have option to protect mails from fire, theft. In addition, later we are thinking of adding more features like operating wheelchair via voice commands and moving wheelchair to particular point (smart mail box, bathroom, kitchen, bedroom etc) just by clicking on display.

Functions of Smart Mail Box for Smart Wheelchair:

  • To alert or notify the user as soon as the mails are received

  • To monitor & protect mails from fire, theft

  • To help disable people or senior citizens to reach to mailbox and other places inside home just by click.

 Five measurable things Smart Mail Box for Smart Wheelchair should be able to do:

  • have sensors to sense movement, temperature, distance

  • send notification after getting mail by sms or by displaying message in LCD

  • send signal by internet connection

  • control, monitor & protect mails from natural disasters, fire, theft

  • move around the desired places in home just by click

 Anticipated cost:

  • Our estimated cost is under $1200 – $1500

  • Our product does not need to be specific size or weight

 Power limitations:

  • Input volt: 100 – 240v

  • Output volt: 3 – 9v

  • 2 AA batteries

 Safety Concerns:

  • Possibilities of wheelchair going offtrack

  • Since the product is focused for disable people, it needs to have safety features. But still need to decide.

 Reliability:

  • It is going to be reliable.

 Market Consideration:

Our target consumers will mainly be disable wheelchair users as well as regular and senior citizens. Our consumers would find this product beneficial because:

  • It will alert people to get their mails

  • People can monitor, protect their mails

  • Wheelchair users can control and move wheelchair to get mail just by click

[Ω] – Prototype I Proposal: Device to Monitor the Grasp of a Steering Wheel

Description of Idea:

The objective of this device is to measure wether or not (and what degree) a person is grasping their steering wheel. We have a main design on how this will be done which involves measuring ultrasonic signals; additionally we will test a competing technique of measuring capacitance.

By applying a transverse signal to a point of the steering wheel, a mirrored phonon transits the wheel back to its starting point. By choosing a frequency that physically fits (many times over), a standing wave can be created on the wheel. By choosing a frequency high enough, those standing waves can be expected to place nodes at wheel mount points, lowering the chance of dampening by the vehicle. Another benefit of high frequencies is the improved chance that the user will cover a part of the wheel that doesn’t have a wave-node.

The circuitry will involve an Arduino, a wein-bridge oscillator, transistor, 1-2 amplifiers, a band-pass filter, a diode-rectifier and sufficient power supplied. (Image to be supplied) The Arduino will turn on/off a transistor attached to the output of the oscillator, effectively start/stopping it. The output transducer will be directly attached to the wheel, as will be in the input transducer. From the input transducer, signal will be sent to a amplifier circuit ( this may be as simple as a single op amp), from the amplifier, we’ll send the signal through a band-pass filter ( as easy as 2 caps & 2 resistors). From there, we’ll rectify the signal via 4 diodes. The analogue input of the Arduino should then read the DC signal and convert that reading to a number that can be visible on 1-2 7-seg LEDs.

We’ll be interested to see what kind of spurious signals are read that come from the vehicle, road, and environment.

Market Consideration:

- Automakers (potential integration with such systems as Attention Assist by Mercedes)
- Insurance companies
- Parental control

Description of Prototype:

Prototype will establish the communication between piezos, an amp and arduino providing usable readings. //see full description above

Samov – Prototype I Proposal: Touch Projector

Touch Projector Team

Description of Idea:

The function of our product is a touch capable projector that can work on any flat surface without the need for a special screen or external sensors.

  • 5 measurable things our product should be able to do:
    1. Should work on any flat surface
    2. Should know when surface is being touched
    3. Should be portable and light weight
    4. Should be able to support at least 2 touch positions
    5. Should be able to have adjustable sensitivity
  • Anticipated cost: $300-350
  • Our product should be portable; should be no bigger than a squirrel and weighs around 1 lb or less and should easily fit in a laptop bag or briefcase
  • Powered by USB port or rechargeable battery
  • Avoid eye contact with projector lens and IR laser diode
  • Should be able to work with everyday usage without no major issues
  • Other product specifications:
    • USB connectivity
    • Resolution: Native WVGA (854 x 480) Max (1280 x 800)
    • Brightness: 20 Lumins
    • Distance it works from: 10″ – 60″
    • LED light source (20,000 hour life)

 

Market Consideration:

Our Target Consumer: Everyday people, including business people, teachers, students, chefs.

Consumer #1: College Student.
Insight: Liked idea of portability and use on any surface. Liked the ‘touch’ controlled aspect of the projector.

Consumer #2:  A mother.
Insight: Thought good for projecting recipe from internet onto the counter and scrolling through it without getting the keyboard dirty.

Description of Prototype:

Our prototype will get the basics of sensing touch location on a surface on the same plane as the projector.  We will do this by having an IR emitter/sensor detecting parallel along a flat surface (table). A disruption to the IR signal will indicate that a finger is touching the surface. It will then need to be translated into a x-y location which will later be translated to the the location on the screen.

HTC (not the phone company) – Prototype I Proposal: Pedal Pal

Description of Idea:

  • The function is to control digitally an anlogue synthesiser for musical instruments, namely guitar pedals
  • This will control the synth parameters such as trebble, bass, ect. store preset settings to be recalled, be able to adjust settings and save changes with foot switches, display onan lcd the paramters chosen and other relevant information, be able to control multiple effects, a chick magnent
  • $100-$200
  • 9v is standard for pedals but arduino is 5
  • 110% reliable
  • Needs to maintain the sound quality and tambre

Market Consideration:

Many tone junkies love analoge pedals and will have three of the same pedal with different settings. This fixes that.

Description of Prototype:

We have two ideas for implementation. One uses servos to adjust the potentiometers of a traditional synth. The other uses digital potentiometers instead. The first idea is easy to install and the other requires modification of the original circuit. We plan to build both for first protoype and test both. All results will be used indeciding on a final method.

Team Name – Prototype I Proposal: DoorTextChecker


Description of Idea:

The big idea of this product and what we want to build is something that can check if a door is opened or closed.  From there the user can lock said door if needed.  We want this to be able to be done remotely, preferably from a phone app or website. The other item that defines this from a security system is that there is no monthly fees, it just works off of a compute with a web connection.

5 measurable items to this:

  • Lock/unlock door
  • Close/open garage door
  • Monitor open/close
  • Work remotely
  • Customizable/able to handle whatever amount of doors needed ect…

We are guessing the overall cost might be around $200 dollars.

The other big item is that this product needs to be very accurate and reliable.

Market Consideration:

There are two different types of consumers that this product could be marketed to small business owners and people who are frugal but want peace of mind.  So the small business own this is practical because if they want to implement some sort of security system in their business but don’t want to spend monthly fees on a security system this can be a practical solution. Also for people that once peace of mind this can be great because if they want to see if a door in their house is locked they can check and see if it is using a computer or phone and if a door isn’t locked, lock it up. Giving them peace of mind in this uncertain world.

Description of Prototype:

The basic goal of this prototype is to be able to make sure we can get two rf modules to communicate with each other and relay data from one module to another and have a computer receive this data. So what it will do is see if a switch is triggered or not, and  relay that information to a computer using the rf modules.  The overall project entails having something for a garage door and a dead bolt that can be wirelessly monitored from a phone or computer, you can lock them remotely and unlock them remotely also. The other goal is for this to be expandable to work in any house

Steering wheel 2: Prototype I Proposal: Smart Steering Wheel

Description of Idea:

  • The steering wheel sensor is a device that will sense when a driver starts to fall asleep by sensing when the drivers hands leave the steering wheel for more than 2 seconds and then alerting the driver that there is a problem.
  • The steeering wheel sensor should be able to engage itself when the car is put into drive, sense that the drivers hands are on the wheel and when hands are removed from the wheel, be able to alert the driver when hands are removed from the wheel.  
  • Costs should be around 250 dollars for the steering wheel with device mounted in side.
  • We will have to be careful not to interfer with any of the cars safety features.

Market Consideration:

The sensor will be marketed to any drivers that tend to drive long hours or over night.

Description of Prototype:

The 1st prototype will consist of a steering wheel embeded with the pressure sensors with the ability to display the amount of pressure exerted on the wheel and send a electrical signal tha will light a LED when pressure drops to zero.
