The Client: A young man diagnosed with muscular dystrophy requires the use of a respirator and a
wheelchair. He has no muscular ability or control. Assistance is needed to operate mechanical devices.
His primary concern is to complete simple tasks independently. He would like a TV remote control that
he can operate.

Lucky 7
Project Description: A “sip and puff” apparatus
activates pressure switches by sipping or puffing through
the tube of the device. Four pressure sensing switches
are wired to a TV remote control circuit board. Plastic
tubes are attached to the sensors to control volume and
channel commands. This device has the potential to
control a variety of electronic devices. .All of the exposed
wiring is encased in a protective plastic encasing.
Due to the client’s physical limitations,
a head-ear attachment was designed
to facilitate the use of the device.

Lucky 7
Sip and Puff system
The major objective of the “sip and puff” design is
to improve the client’s independence. The team
developed a four-command hands free interface.
In the future, this interface can be used to control
basic computer commands, household lighting, and
volume or track number on an audio system.

The Project: A commercially available garage door opener
was adapted with custom parts to meet the client’s special
needs. The runner moves along an aluminum track by
means of a more durable screw drive system that can
withstand more stress. Stabilizers were designed to secure
the motor and track to the concrete floor. Light sockets on
the garage door opener were modified to turn on when the
client opens and closes the door using a remote control.

Engineering team and client
After researching different models, the Genie
Excellerator was chosen. It features a ½ horsepower
motor, screw drive, remote access entry, and a quiet
motor. Modifications were made to fit the garage door
opener to the client’s sliding glass door. The aluminum
track was cut the correct length. A custom “clip” was
fastened to the track of the door. An arm was designed
to attach the runner to the clip.

HaSh JaSh of the East
Project: The team developed a tadpole style recumbent tricycle. The frame was custom built by machining
several bicycle frames and parts. The tricycle features a back-supported seat, toe and heel straps, medial foot
stabilizer, a seat belt and shoulder straps. The steering system and drum brake can be operated with one hand.
The trike has two front wheels and one rear wheel, a feature that renders it more stable than a bicycle .

In designing the tricycle, the team wanted a project
that closely resembled the bicycles of the client’s
siblings. Also considered was the child’s need to feel
free from the constraints that a wheelchair imposes
upon its rider. Thus the idea of the recumbent tricycle
was born.

The Project: Team
members developed a
multi-level elevating
table named the Tablift
2005. It features a
raising table section
with two shelves to
enable access to more
items for individuals
who may need to work
from a bed. It provides
stationary storage for
accessing items while
the bed is in a down
position. It has a lifting
portion for easy
accessibility of items, a
sturdy rack and pinion
lifting mechanism, an
easy pull-out desk,
interior electrical jacks
for medical equipment,
an exterior power strip
for other equipment,
and sturdy casters for
easy movement.

The Tablift’s components enable the client to reach items that were previously inaccessible. By providing a
lifting portion to a bedside table, the Tablift provides three times the storage of conventional bedside tables for
individuals with limited use of arms and hands. A physical barrier made of accordion blinds prevents objects
from getting beneath the lifting mechanism. A space between the table top and the exterior was added to
prevent injury to fingers while lowering the device.

21
Changing the Stars
A team member explains the
project design to a judge.
The client already manipulates
objects using a head pointer
affixed to a baseball cap. This
setup causes her body to
overheat and her head to sweat.
A better solution to the head
pointer provides open air
ventilation.
