Our engineers will
cover every facet of design implementation. Our core strength
is circuit development, with additional services to complement
the core service. These additional services include PCB design
and layout, schematic capture, mechanical CAD for housings and
packaging, embedded microprocessor programming in C and
assembly and DOS/Windows programming services that complement
the product development. Pioneer Microsystems will also build
and program custom test fixtures to complement production
needs. An additional service is BOM management, parts
procurement (with a specialty of 'engineering' based parts
substitutions) and very short run 'zero defect' assembly
services.
'How do I know that
you can handle my project?' you ask.
Listed
here is a partial bibliography of completed projects that have
been performed.
Project example 1:
The
first example project is a USB based device that involves
digital inputs and a PC application that manages 'first
pressed' results on the screen. The embedded code implements a
USB end device in software, and the PC application, written in
Boralnd C++, implements the USB dirver and user interface code
to communicate with the end device.
Project example
2:One
company came to us in need of all of the electronic controls
and software for a system that recycles and charges freon in
automobiles and trucks. A system was designed with a grpahics
LCD display with a 16 bit processor, and a sensor interface
board with an 8 bit processor. The unit has two USB ports. One
serves a printer, and the other a flash thumb drive. The system
has a bootload feature, where it checks for a file on startup.
If present, this file is read in and used to overwrite the
whole application. When the application runs, it checks the
flash drive for files that represent new menu text in 3
languages, as well as database files that represent data on
cards or trucks. These files are loaded and stored in memory.
If the user wishes, a report or parameter settings file can be
saved onto the flash drive as well. The sensors board uses a
weigh scale to resolve a 22Kg container to mere grams, to allow
highly accurate target charges to be achieved.
Project example
3:One
of our clients manufactures transformer temperature control
panels for the large transformer manufacturers. Their old
technology was an analog based control scheme with a dash of
relay logic. Due to increased market pressure to offer a
microprocessor based solution that has RS485 communications and
temperature trending, they decided to seek outside help. We
have re-developed two of their products, which are now based
upon an 8 bit microcontroller. Both units are in production at
this time.
Project example
4:One
client in the pharmaceutical industry has strong talents in the
mechanical design of tablet presses, but no inside expertise on
electronics development. Three devices have been designed
for them. The first is the 'capture' of an old load cell peak
hold card of which the documentation and drawings had been
lost. The second was a low noise low drift load cell amplifier
module. The third is a 0-10V voltage programmed 50Watt halogen
lamp dimmer board for their optical recognition system. Two
more designs are in progress at this time.
Project example 5:
Pioneer
Microsystems recently completed the fabrication and programming
of two custom PCB production test fixtures for a local
ventilator product manufacturer. One of the fixtures is
intelligent enough to study the serial port data from the
target board and determine the test success or failure of the
test.
Project example
6:One
customer needed a motor speed control for a fractional DC brush
motor. All of the off the shelf controllers lacked some
key feature, such as accurate current feedback, reliable
performance, or a disable input. After significant
experimentation, they came to us, and we designed a straight
forward SCR single phase speed controller for them. The
new design has met every one of their product feature
goals.
Project example
7:Another project involved designing a
complete 3 phase DC brushless 6HP motor speed controller from
scratch. High power DC brushless is not too common, so
off the shelf controllers tend to be pricey. The customer
wanted their own design, in order to sell a complete motor
control package at a more competitive cost. The design
incorporates a full 6 pack with three additional diodes in
order to implement a true safe brake function.
Certainly, you can see that our company is serious about
performing electronics product design. There are many other
examples of successful project designs as well. If you have
interest in our services, please call us at USA-412-369-9920.
