Additional Product & Systems Experience:

• Line-sensor head and associcated instrumentation that measures grey-scale surface reflectance, by scanning (through a gap) the underside of items moving on a conveyor line.
 

• Probe-head with flexible array of fibre tips that is used to rapidly couple to lateral (planar) waveguides in the middle of a substrate.
 

• Video-based target sighting system with a patented elevation mechanism.
 

• Process engineering of a rapid thermal system, including control and calibration at high-vacuum and high-temperature, for thermal oxidation, nitrogen "hardening", and annealing of thin films.
 

• Embedded data acquisition system in which a synchronized parallel array of three microcontrollers is used to sample a line of 48 ‘pixels’, and output real-time data to an external host using a high-speed serial (CAN) interface.
 

• Parallel Unix-based multi-processor (PowerPC & SHARC) digital signal processing software, for high-speed analysis of acoustic (sonobuoy) signal data, including spectral analysis (FFT), audio resample filtering and directed cardioid (beam-forming) spatial processing.
 

• Algorithmic process that fuses inertial navigation and odometry signals, reducing the effects of (acceleration) integration error and of wheel-slippage on the position estimation of wheeled robots.
 

• Opto-electronic feedback control system that maintains a thermally-actuated variable optical attenuator (VOA) device at a fixed optical output power level.
 

• Hybrid stabilization system for an existing non-stabilized surveillance platform, where limited bandwidths of image- and motion-based feedback signals, and image- and motion-based correction, are combined to stabilize the platform, with minimal physical system modification.
 

• Steering control laws and proof-of-concept simulation to facilitate simultaneous path-tracking and obstacle-avoidance (automatic piloting) of a proposed autonomous planetary rover.
