Klaus R. Schambeck
My Resume : Senior design engineer (project leader) with work experience since 1978
Education : BSEE (1978) from TGM Vienna Austria (US citizen)
Design example : The "Cortez-Project"
can be used to show the variety of my design experience in several fields.
Work history : Worked for several companies as design engineer
(employee), (ITT Austria, Philips, Margaux Controls, WYSE technology, Apple Computer
(contract). Self employed since 1987 with contracts till present.
Software (Firmware) : Several assembly languages for
INFINEON / SIEMENS (C161CS, C164CI, C167CS, CAN-bus, etc), INTEL (80x96,
80x86, 8051, etc), MOTOROLA (680xx, 68xx, especially the 683xx family including custom TPU
Hardware : Digital and analog designs involving a variety of CPUs
(Infineon / Siemens, Intel, Motorola, etc...), PALs, PLDs, ADCs, DACs, OP-AMPs, etc
Features : Specialized in embedded controllers including motion control (robotics), data acquisition (process control), etc multitasking framework with high speed real-time interrupt support. Also Win32 instrumentation and control user interface design using Borland C++Builder. Java J2SE and J2EE internet network software.
Newest project :
PTI corporation (Penryn, CA). Designed custom contoller to monitor DC parameters of up to 50 paralleled RF-amplifiers including their remote control over the internet. Hardware based upon Infineon C164CI microcontroller with various ISR supported SPI peripherals. Firmware written in “C” and assembly. Remote control software written in Java J2SE and J2EE.
Earlier projects :
1999 to 2000 : Redwood Microsystems (Redwood City, CA). Wrote RISM concept monitor kernel for Infineon / Siemens C16x family of microcontrollers (assembly and “C”). Designed control hardware (analog and digital) for new generation of Micro-Valves.
1997 to 1999 : Protogene Labs (Palo Alto, CA) Sole responsibility for motion control of chemical reagent deposits with piezo-jets. Dual CPU high performance design utilizing two MC68736s with QSPI I/O and inter-processor-communication.
1st CPU handles up to 6 stepper motors with full parallel processing
and motion, accel / decel. programmability. With optional quadrature-position and index
detection. Selectable normal-stepping (200 / 400 Steps / rev) or micro-stepping (up to
12800 steps / rev, without speed degradation). Custom TPU code for table driven interrupt
supported stepper motor control . Queing of commands and parallel processing utilizing the
UCOS (Copyright Jean J. Labrosse) multi-tasking operating system.
Below you can see a few pictures of the 1st prototype and lab-setup showing the glass-array chemical reagent deposit system
Earlier projects :
1995 to 1996 Instruments for research and industry. Sole responsibility for the whole project (concept, HW/SW design and mfg) of a temperature and pressure/vacuum controller for chemistry labs. It was based on the Intel 8098 (8x96, 8x196 family) 16 bit micro-controller with built in 10bit ADC. The analog front-end had 4 overlapping autocalibrating ranges with polarity detection and achieving 13 bits of resolution by using standard low cost components. Analog inputs are T, J, K type thermocouples, RTDs, silicon based mV pressure/vacuum sensors and high-vacuum const-current heated pirani gauge type sensors. Micro-Craft manufactured 400+ boards.
1994 various small contracts including high speed
digital design for disk-drive manufacturing testing (various 22V10 PLD state-machine
designs in CUPL). 80198 based motor control firmware for cassette eject of tape-drive for
RByte-inc. Touch-screen control firmware for Inforite-corp (real-time critical assy and
"C" for Intel 8051).
1991 to 1993 US-Comlink. Wrote Firmware for 68HC11 based pre 2nd generation highway-emengency-call-box controller. Designed 2nd generation controller based on Motorola 68332 including initial port of 68HC11 based firmware. The controller managed 5 serial channels (Rockwell-modem, 4 ext SIO), a clk/data programmable Motorola cell-phone and various safety switches (battery-management, solar-panel, etc).
1988 to 1990 Savant Instruments. Controller for heated high vacuum centrifuge based on Motorola 68000 CPU. Complete digital and analog hardware design (thermocouple inputs for temp. and 10kHz heated thermocouple inputs for Pirani high-vacuum sensors) plus firmware driver design (assembly and "C"-language). 2nd project was based on similar digital design and precision 3 wire RTD sensors added to the self calibrating analog front-end. There have been 1000+ boards produced at Micro-Craft.
