Analog data starts off in many forms:
temperature, pressure, intensity of light, color of light, relative humidity, distance, speed,
acceleration, inertia, force, torque, strain, length and weight to name just a
few. But they all have to be converted to volts or frequency and we are
experts at doing exactly that.
We have a wide range of expertise with
RTDs, thermocouples, thermistors, IC temperature sensors, pressure sensors, Peltier coolers, Hall
effect devices, passive infra red motion sensors, rotary encoders, IC relative
humidity sensors, and other
transducers.
Process Control
Most of our projects
communicate and accept overall directions from an operator or a larger
computer, but the moment-to-moment decisions are made on the spot without
intervention. They are the sorts of thing that used to be called
embedded controllers, until that term was stretched beyond all recognition.
Clearly, this covers a
huge range of possibilities. We have done projects from battery powered
to tens of kilowatts, from fully self-contained to products that are in
constant communication with the outside world. Since it really isn’t possible
to describe your needs without hearing from you, please
contact us with your idea or need.
Communication formats
Almost every embedded product needs to
communicate with a host. We have used RS-232, RS-485, CAN, J1850,
infra-red communication, and
Bluetooth.
Displays LCD VFD
We have created displays using off the
shelf vacuum florescent display (VFD) modules. These are programmed
simply by sending strings of ASCII characters. We have also rolled
custom VFDs from components where we had to decode the individual dots and
refresh the display. The buy-build decision is driven by cost and
available development time. The product that had the built display had
it on the main processor board, so the cost saving was significant.
We have also done LCD displays that
display characters and graphics.

Peltier Coolers
Peltier coolers are plates of lead crystal
with electrodes on them. Passing current through them transfers heat
from one side of the plate to the other. But be careful: too much power
make the whole plate run away and overheat. Neither side gets cool then.

Schematic Capture and other services
We can provide your
company with any or all phases of product design, including: project
definition, hardware design, PC board design, layout and fabrication,
software/firmware, product integration, and documentation. We can even
take care of production if you so desire.
