Designing Inflatable Suit (In Progress)
Design 1:
In the Existing Jacket with stretchable pockets to embed the air pouches, the stretchable pockets are changed to

Design 2:
Contact Company: Choya Toys Company (China) www.chinaplushtoys.com
The Design Progress is in progress. The Drawing Design will be sent to the company to fabricate a suit for the Huggy Project.
Since this company has done various designs of inflatable suits, even for the 2008 Olympics, and Local Balloon Companies are unable to make such inflatable, we have concluded to order form this company.

This is some of the example suits that they have made.

New Program for Demos

A new program is written to simplify the data transfar between the input device and the output circuit.

Initially, the data read from the doll (Bluetooth Dongle) was sent to the other computer to simulate haptic communication.
Now, the requirement of another execution in between two devices is eliminated.

As from the Bluetooth Doll of input side, the pressure Level from 0 to 255 (lowest to highest) is sent from the readings of 12 sensors. The data sent from the bluetooth doll is continuous with the format of [XS---S---S---S---S---S---S---S---S---S---S---S---], where --- are the applied pressure values onto the doll.
The computer which captures the bluetooth data will execute the data and differentiate the pressure values into 10 levels (0 to 9) and add into the command package.

The simple command package [X: Pressure Value: Y: Pressure Value: Z] is sent from the input part to the output device directly.

My teammate, Ben, has also reprogrammed the Output Device to act as stand alone except reading the commands from the Serial Com port of the computer.

Ideas on using BioMetal

Biometal can contract into curvier shape when current is fed through it.
More Information


The following is the design of First Level: Using biometal to contract the cloth tube.

As in the following picture, the biometal thread can be put inside the tube-shaped fabric and feed the current through the metal to transform the metal into more curving shapes.

Figure 1 : Level 1 Design

The following is the design of Second Level: Using other material as medium

In this application, the biometal wire is used to pull the rods (made of some heat resistance material such as clay or ceramic) together to apply squeezing force on shoulders.
When current is fed trhough the bioMetal wire, it will pull the rods together and the shoulder pad will become more convex from resting positon.

Figure 2 : Level 2 Design

These can be put on the shoulders (and on other parts as well) of the huggy pajama.

04/11/2008 Meeting Minutes (Draft)

Making use of BioMetal Material

This metal strands contract when current passes through.

Is it easier to control?

Idea: Finger Shaped Application to embed in the jacket

Problem: Heat insulating

Brainstorm for :

1. How to provide haptic feeling

2. Embed into mechanism (how to build small modules based on the strings)

Recommended Material, BMX up to 200% extension.

Shaped Memo Alloy

Next Meeting: Friday 1:30 to 2:30 pm

Prepare Sketches for this by Thursday.

To recharge Bluetooth device's battery

Power Supply Setting : 5.6 V, I < 200mA ;

Connect in series with a 10 Ohm Resister;

Charge at least about 2 hours;

Specially Shaped Balloons

Who can do these?
What is the price?
How to order?
How long will it take?
