HELD EXAMPLES
QuitKey

The
researchers and psychologists at PICS, Inc. developed
the behavior modification technology and demonstrated it to be an
effective
tool for smoking cessation, without use of any drugs. When it came to
realization of the product in a small electronic, rugged, and
inexpensive
device, they turned to Bridgekey for assistance.
QuitKey is based on a single chip processor, custom LCD,
custom case, and a single lithium coin battery.
Modeled after an automobile remote control,
QuitKey is designed to fit
comfortably in to your pocket or purse.
The hardware includes a single pcb with custom masked
processor and custom LCD panel. Two rubber keys control the operation. Small piezo buzzer is used
to generate a
variety of sounds to augment the user interface.
The functionality consists of three major section - smoking
behavior modification algorithm, user interface, and hardware control.
The
software was developed in C and demonstrated using a PC based Simulator. Upon approval of the
Simulator, the high
level C code was manually translated into assembly code suitable for
the
embedded target processor.
The
plastic case was first developed using high resolution
computer graphics. A
3D computer model
was converted into a physical stereo lithography generated model.
Later the same files were
used to design the full
injection mold tools.
SleepKey
Following the
success
story of QuitKey, Bridgekey and PICS
have developed SleepKey. This product is based on sleep pattern
behavior
modification algorithms developed by PICS researchers.
The machine utilizes a high performance, high integration
microprocessor. The devices employ a low frequency speaker and a
vibration
motor to generate necessary user interface signals.
The device has a custom LCD and several
rubber keys providing user interface.
The
software implements algorithms developed by PICS
scientists. The user interface was developed by PICS and Bridgekey.
Bridgekey
implemented the BIOS (hardware support) subsystem.
SleepKey
utilizes a processor which is also available in a
higher cost Flash memory based version.
he Flash based units were used to test
functionality and confirm the
algorithms. The
advantage of the Flash
technology is that the product can be easily reprogrammed with new
version of
the code until all features function as desired. Upon approval, the
Flash code
is transferred directly into a masked ROM, eliminating any possibility
of a
costly translation error. The masked ROM devices have the necessary low
cost to
meet the overall product price point.
Research devices have been developed that allow the
scientists at PICS to experiment with different algorithms for the
sleep
behavior modifications. They
use the
Flash based SleepKey machines with a small on board connector and
special
interface hardware to test different versions of the software.
The Flash based devices
have shown to be an effective way to
develop the hardware and software because it allows the customer to
test the
device in virtually identical configuration as the final product.
5+ Language Translator
Bridgekey
has developed this 5+ language translator for
Seiko Instruments. The
dictionary is
based on world renown Berlitz data base.
There are over 28,000 words and 1200 phrases
for each language. The
database is compressed us9ing a highly
asymmetrical lossless compression technology yielding high compression
rates
and fast decompression time.
The
product
provides basic word and phrase look up as well as these functions:
·
search
for all phrases containing a given word
· select
a phrase from a categorized list
· four
function calculator
· currency
converter with a calculator function
· measures
converter with a calculator function
· clothing
size comparison chart
· context
sensitive help function in 6 languages
· ‘Hangman’,
‘Flash Card’, and ‘Jumble’ games
The hardware utilizes high performance, low cost, high
integration microprocessor with an external masked ROM for data base
storage. An
innovative system turns on the product
automatically when the translucent cover is opened.
Software was developed in
C and extensively tested using a
custom Simulator package running on a Windows based PC.
Following customer's approval of the
Simulator functionality, the software was cross-compiled to the target
processor.
IdeaFisher

IdeaFisher
Systems, Inc. has developed and patented a unique
and innovative brainstorming tool designed to help you think
creatively. The
product is recommended for writers, designers, advertising executives.
entrepreneurs, engineers, inventors and educators.
Bridgekey, under a
contract from Seiko Instruments, Inc.,
developed a hand held version of this popular PC program for
IdeaFisher. The
hardware design utilizes a very high integration Epson processor
coupled with
LCD expansion companion IC, low power SRAM, non-volatile EEROM, and a
large
masked ROM to hold the data base.
The
hardware and software was tested using a table top test
system. Different
software versions were
loaded into the test system using PCMCIA memory cards.
The testing was ongoing concurrently in USA
in California, New Jersey and New York and also in Japan. New
software versions were
distributed via
e-mail to all test sites. Memory
cards were
loaded a PC and then transferred into the test system.
The software for this product, written in C and assembly
code, included:
· development
of user paradigm consistent with the
PC program model
· development
of a simulator
· implementation
of user interface
· data
base compression
· hardware
BIOS
The
product has four different subject (topic) modules that
can be purchased on a custom Internet web site. A system of encryption,
tags
and keys is used to lock and unlock individual modules following the
purchase
by the end user.
