Solutions for real world problems
Clients /Links :
Our clients have created some
interesting (sometimes unique!) products. See
some examples and links to their websites below.
Goembel Instruments contracted with Payload Systems, Elf Electronics, and Littlefield Associates to develop this "flight like" electron spectrometer instrument.
Littlefield Associates provided the analog electronics and HV power
supply design along with a Tcl/Tk based graphical control panel for
ground support use.
|The Center for Space Research at MIT
contracted with us to provide an RCTU (a type of communications
interface) used to communicate with the Chandra X-ray telescope.
(Littlefield RCTU!) is still being used to interface a network of
workstations to the ground based Chandra engineering prototype at the MIT Kavli Institute for Astrophysics and Space Research.
We also developed MIPS R3000 embedded firmware which the
hardware team used to test Chandra's on-board image handling
| QPeak makes leading edge solid state laser systems for research and industrial applications.
Littlefield Associates has contributed hardware design,
firmware development, and VB user interfaces to a number of
programs at QPeak.
|We have worked with Tek-Air Systems
to provide enhanced electronic controls, automation network interfaces,
and production QA/QC tools for Tek-Air's airflow and
environmental monitoring products.
|American Control Technologies Ltd.
called on us for hardware design and firmware development for their
Datahopper product line. The Datahopper provides an innovative
combination of Modbus router/concentrator, local analog and
digital I/O, and on-board user programmable logic functions.
| When Programmed Test Sources Inc.
wanted to add an enhanced GPIB interface to their line of fast
switching low noise frequency synthesizers they contacted Littlefield
Associates. We designed a PCB, FPGA logic, and firmware to
implement the GPIB interface and SCPI command set.
