The design and characterisation of an optical VLSI processor for real time centroid detection (2001)
Journal Article
Boon Hean Pui, , Hayes-Gill, B., Clark, M., Somekh, M., See, C., Piéri, J. F., …Ng, A. (2001). The design and characterisation of an optical VLSI processor for real time centroid detection. Proceedings of SPIE, 4408, 73-80. https://doi.org/10.1117/12.425338

The integration of photo-detectors onto a standard CMOS integrated circuit is presented. This device provides the optical front end for a real time centroid detection system to be used as part of a larger system for implementing a Shack-Hartmann wave...

Consideration of multiplexing in neural network hardware (1994)
Journal Article
Craven, M., Curtis, K., & Hayes-Gill, B. (1994). Consideration of multiplexing in neural network hardware. IEE Proceedings Circuits Devices and Systems, 141(3), 237-240. doi:10.1049/ip-cds:19941103

This paper presents the results of research into a scheme for overcoming the communications 'bottleneck' within hardware neural networks, utilising frequency division multiplexing of amplitude modulated neural signals. The introduction explains the p... Read More about Consideration of multiplexing in neural network hardware.

Two quadrant analogue squarer circuit based on MOS square-law characteristic (1991)
Journal Article
Craven, M., & Hayes-Gill, B. (1991). Two quadrant analogue squarer circuit based on MOS square-law characteristic. Electronics Letters, 27(25), 2307–2308. doi:10.1049/el:19911429

A novel analogue CMOS circuit is presented which performs the arithmetical squaring of a voltage, using the square-law characteristic of the MOS transistor in saturation. The core circuit is constructed from four identical building blocks, which are... Read More about Two quadrant analogue squarer circuit based on MOS square-law characteristic.

Frequency division multiplexing in analogue neural network (1991)
Journal Article
Hayes-Gill, B., & Craven, M. (1991). Frequency division multiplexing in analogue neural network. Electronics Letters, 27(11), 918-920. doi:10.1049/el:19910575

Frequency division multiplexing has been studied as a means of communication between neural layers in an analogue multilayered perceptron neural network architecture, trained using the back-propagation learning algorithm. Simulation results on networ... Read More about Frequency division multiplexing in analogue neural network.

A hybrid neural network/rule-based technique for on-line gesture and hand-written character recognition
Conference Proceeding
Craven, M. P., Curtis, K. M., Hayes-Gill, B. H., & Thursfield, C. A hybrid neural network/rule-based technique for on-line gesture and hand-written character recognition.

A technique is presented which combines rule-based and neural network pattern recognition methods in an integrated system in order to perform learning and recognition of hand-written characters and gestures in realtime. The GesRec system is introd... Read More about A hybrid neural network/rule-based technique for on-line gesture and hand-written character recognition.
