Expert in Microcontroller-based Product Design
Expert was the lead Software Designer and System Hardware Architect in the development of AT&T's highly successful HT5000 series of cordless telephones. First introduced in 1985, these telephones were the first microcontroller-based cordless telephones ever marketed. Expert played a larger role than mere software development--he was active in product planning, feature definition, cost reduction, and hardware design of the HT 5000 series and its derivatives. He is also co-inventor of an award-winning battery-life-extending patent that has generated significant income to AT&T via cross-licensing.
In addition to his involvement in AT&T's cordless telephone design, Expert has also been involved with wireless control development using diffuse infrared (IR). He is also active in AC power-line control techniques (X-10 and related interfaces, vendor ICs for Powerline Modems). He tracks developments and devices involved with the recently introduced IrDa standard for infrared data transmission.
Expert's favorite design projects are those centered around a microcontroller-based control element. He has been involved in a wide variety of microcontroller-based designs for consumer, industrial, and military applications. His firm provides complete turnkey development facilities for microcontroller hardware and software development using devices made by Intel, Motorola, Texas Instruments, PIC Microchip, National, and others. In addition to software design, Expert's participation typically includes involvement in real-time operations, hardware design, system design, product conceptualization, and PCB design. His broad technical exposure combined with his business perception and experience allow him to contribute significantly in product definition, design-to-cost, and design-for-manufacture activities.
Expert has been an engineering "generalist" for 20 years and has expertise designing control systems, switching power supplies, data acquisition circuitry, sensor conditioning, and TTL/CMOS digital logic circuitry. He has designed dimming control devices for HID and HPS lamps in the high-voltage lighting ballast field. About the only area he has not had significant design experience is RF design. As a result of his broad design exposure, he has been retained as Electronic Design Magazine's Consulting Editor for its most popular regular feature, Ideas for Design.
Expert has been involved with custom and OEM-based embedded systems. On the OEM side, he has experience with STD-BUS, PC/104, MicroMint, and Z-World control cards. He has developed, debugged, and consulted on hardware and software aspects of these systems. His software experiences have been in assembler, Microsoft C, and Archimedes C.
In addition to his hardware-based, real-time, and OEM systems solutions, expert has been involved with system-level software design. He recently developed a PC-based, menu-driven support application ("Custom Software Generator") for an alarm company that allows field personnel to select devices and define the system configuration and system options in a menu-based environment using a laptop. This application then compiles the configuration and performs a download to the hardware host. His software experiences in this area have involved 80x86 Assembly and Microsoft C.
