manufactures products that span a wide range of markets and
industries. We have designed and built custom electronic products
currently in use at major international corporations such as
Lexmark International, Toyota Motor
Manufacturing, and Weyerhaeuser. We've also
developed electronics for many small companies and
universities. If you need a custom electronic product, we can
design and manufacture it.
We are well versed in analog and
mixed signal, but truly excel in digital
designs. For most small products, the Thinking Devices solution is
composed of a microcontroller with some very efficient and
extremely reliable firmware code, interfaced to the external world
through some network of custom electronics. We've already
developed code and electronics for almost every common requirement
and a lot of unusual tasks as well, so your custom design will not
require completely designing everything from scratch. Most designs
have only one or two aspects that we haven't already done numerous
times. A very abbreviated list of product
features we've already implemented includes:
LED displays and LCD operator panels.
inputs and outputs.
Pressure measurement and pressure
Audio output - piezo
buzzers and speakers.
Speech recording and playback.
frequency analysis of complex waveforms.
Load cells or force
sensitive resistors for force or weight measurement.
control - servo, stepper, universal, brushed DC, synchronous
Pneumatic and hydraulic valves.
Inductive and capacitive
Numerous types of conveyors and
Encoded digital RF data transmission.
flash memory storage.
All of our products include complete
documentation sufficient to allow the work to be independently
replicated without any additional engineering. The end user
documentation is clear and concise. We deliver all documentation
in non proprietary industry standard
formats, such as HTML, DXF, JPG, PDF, etc.

This is a low cost custom industrial
product used to prevent unauthorized access to modem connected
manufacturing equipment. We provided a complete solution,
including on-site installation and testing.
Thinking Devices designed and manufactured a
solid state digital control system to replace an open loop control
system in an existing semiconductor wafer washer. The original
system used relays and mechanical timers, with no process
monitoring. The upgrade provides complete closed loop process
control with programmable high/low alarm settings, a password
protected maintenance menu, enhanced safety, and improved
maintainability. The operator interface was reduced to four
pushbuttons. This equipment is now almost maintenance free in a
24/7 manufacturing operation. Upgrading the existing equipment
allowed the customer to retain their capital investment while
benefiting from substantial upgrades, improvements and many
new features and capabilities tailored to the customer's needs.
This printed circuit board was used to
modify a piece of manufacturing equipment to avoid a potentially
hazardous condition by using a mechanical interlock to prevent an
operator from removing the lid of a pressurized vessel. A
redundant fail-safe technique is employed. The large custom
pressure sensor at the upper left was manufactured in-house using
a small pressure sensor intended for light duty PCB mounting. The
low cost sensor was packaged in a very rugged housing to survive a
harsh industrial environment. It incorporates an integral filter.
The pressure sensor is quickly calibrated in software with a
simple two point calibration procedure. The calibration values are
then stored in nonvolatile flash memory. During operation, the
pressure is displayed on a three digit LED display located on the
back side of the PCB. The pressure display is accurate to better
than 1 PSI over the range of 0-120 PSI. This PCB was designed to
replace an analog pressure gauge in an
existing machine panel, simplifying installation while improving a
familiar user interface. We provided a complete solution,
including on-site installation and testing.
Data Acquisition System
This prototype high speed 4-channel
encoder data acquisition system is a simple and effective solution
to a difficult problem. There are five processors collaborating
underneath the modest exterior, each operating at 5 million
instructions per second (MIPS). There's also 8 MB of flash memory
to store data. Each of the four channels of data is sampled with
200 nanosecond resolution, which means this device can acquire
four discrete data samples in the time required for light to
travel 196 feet! The data is buffered to flash memory, then
transferred to a PC via a 115,200 baud RS-232
serial port. We built two of these prototypes, at a cost similar
to an off-the-shelf solution, had one existed.
are just a few representative examples of the custom electronic
solutions we've provided for industrial and commercial customers.
Thinking Devices is also developing products for internal
manufacturing and direct marketing. These internal products are
being developed in the background. We have adequate capacity to
develop custom products for our customers, while using the
internal product development to remain productive when outside
work slows. This allows maximized utilization of our resources
while ensuring fast response to customer needs.
