Computime Systems Ltd
Leeds, England
External Consultant
I helped troubleshoot and further develop Computime’s time and attendance
systems systems both in regard of electronics and firmware design. The T&A
clocks were based originally on Z80 and NEC V40 chipsets were networked using
RS-485 over up cable spans up to 1km cable and with a host computer using
RS-232. I developed a real-time executive which implemented cooperative
multitasking in C and Z80 assembler. The high level functionality was
developed in C by Computime’s development team and I integrated the code into
the host hardware.
As the technology in the clocks became obsolete with a consequent rise in
manufacturing costs, Computime re-engaged me to develop the successor. The
replacement clocks had a number of requirements over the original including the
ability to communicate using TCP/IP networking and to significantly reduce
manufacturing costs.
As before I developed the hardware and low-level software and Computime’s team
developed application level code. The new clocks were based on Atmel’s
AT91RM9200 ARM processor and ran Linux. At the time of development Linux was
relatively recent on the ARM platform so I developed both utilities and Linux
device drivers for the platform. I contributed patches to the then-current
Linux Ethernet driver and added code to support the Ethernet PHY chips used in
Computime’s design.
2003 – 2012, 1993 - 1997
Officelogic International Ltd
Skipton-in-Craven, England
Senior Development Engineer
OfficeLogic Internalional Ltd developed software distributed through Internet
Service Providers to simplify the process of installing and using internet
software suites on Windows PC based systems. Notably OfficeLogic developed and
supplied BT’s Expert Internet product.
I was responsible for the design and implementation of standards-based Internet
Fax software suite including fax to email “on ramps” and “off ramps”. As part
of this development process I was a participant in the IETF standards
development process in the FAX and VPIM working groups both on the IETF mailing
lists and attending IETF meetings.
In addition I was involved in the design and implementation of an HTTP/1.1
content filtering proxy for BT Expert Internet. This was an early
implementation of detection and blocking of undesirable content as found on
contemporary web sites.
1997 – 2003
Other Experience, Self-Employment
Whilst self-employed, I developed a number of small embedded devices based on
Motorola 6809 and PIC microcontrollers, including beer pump dispensers, vehicle
immobilisers, power amplifiers for in-car entertainment, automatic hand dryers
and central heating controllers where build costs are strictly limited. I also
guided clients through technical processes such as EMC testing for CE and PACT
approvals.
Consultancy for ultrasonic equipment tagging and tracking for use in
sensitive and hazardous environments.
Development of system to automatically monitor coin hoppers on pub games
machines and reconcile reported takings communicating on-line in real time
directly to companies leasing machines.
I developed higher end ARM/Linux systems for Time & Attendance systems,
monitoring and verifying coin hoppers on cash based pub games machines and tyre
pressure monitoring.
