Recognition of simple gestures using a PIR sensor array (2012)
Journal Article
Wojtczuk, P., Armitage, A., Binnie, D., & Chamberlain, T. (2012). Recognition of simple gestures using a PIR sensor array. Sensors & transducers, 14, 83-94

We present an approach that is intended for simple gesture control using a relatively inexpensive pyroelectric array detector. The detector is manufactured using standard wafer processing techniques. It consists of a 16 element passive infrared senso... Read More about Recognition of simple gestures using a PIR sensor array.

Harmonic errors associated with the use of choppers in optical experiments. (2006)
Journal Article
Benjamin, K., Armitage, A., & South, R. B. (2006). Harmonic errors associated with the use of choppers in optical experiments. Measurement : journal of the International Measurement Confederation, 39, 764-770. https://doi.org/10.1016/j.measurement.2006.02.008

Rotating chopper wheels are used to modulate optical radiation in many experimental systems, typically for measuring the frequency response of an optical system. The assumption is often made that the chopped radiation varies sinusoidally. In practice... Read More about Harmonic errors associated with the use of choppers in optical experiments..

Using low-cost infrared detectors to monitor movement of pedestrians: initial findings. (2004)
Journal Article
Kerridge, J., Armitage, A., Binnie, D., Lei, L., & Sumpter, N. (2004). Using low-cost infrared detectors to monitor movement of pedestrians: initial findings. Transportation research record, 1878, 11-18. https://doi.org/10.3141/1878-02

Monitoring the movement of pedestrians in everyday environments is difficult, especially if accurate data are required. Typically, data pertaining to the origins and destinations of pedestrians as they move around a space can be obtained only by eith...

Teaching multitasking to electronics and computing students (2001)
Journal Article
Armitage, A. (2001). Teaching multitasking to electronics and computing students. International Journal of Electrical Engineering Education, 38, 338-347

Although widely used in the solution of engineering problems, multitasking is conceptually as complicated as parallel processing. A simple system that covers the key features of multitasking in a short time is presented. A description is given of its...

A comparative study of integrated ferroelectric polymer pyroelectric sensors (1998)
Journal Article
Setiadi, D., Binnie, D., Armitage, A., Benjamin, K., & Weller, H. (1998). A comparative study of integrated ferroelectric polymer pyroelectric sensors. Integrated Ferroelectrics, 19(1-4), 33-47. https://doi.org/10.1080/10584589808012694

This paper presents a comparative study of integrated pyroelectric sensors based on ferroelectric polymers. Two deposition technologies of PVDF and VDF/TrFE copolymer, both compatible with IC manufacturing, are presented. A 9 μm PVDF film is bonded o...

An integrated charge amplifier for a pyroelectric sensor. (1997)
Journal Article
Setiadi, D., Armitage, A., Binnie, D., Regtien, P., & Sarro, P. (1997). An integrated charge amplifier for a pyroelectric sensor. Sensors and Actuators A: Physical, 61, 421-426. https://doi.org/10.1016/S0924-4247%2897%2980299-3

This paper presents an integrated charge amplifier that measures a small charge. This charge is generated by a pyroelectric detector. The charge amplifier consists of a single-stage c-annon source configuration with a passive feedback network. The ch... Read More about An integrated charge amplifier for a pyroelectric sensor..

An Investigation into the improvement of Local Minima of the Hopfield Network (1996)
Journal Article
Peng, M., Gupta, N. K., & Armitage, A. (1996). An Investigation into the improvement of Local Minima of the Hopfield Network. Neural Networks, 9(7), 1241-1253. https://doi.org/10.1016/0893-6080%2896%2900017-2

The paper investigates the improvement of local minima of the Hopfield network. A local minima escape algorithm (LME algorithm), is proposed for improving local minima of small-scale networks. Experiments on travelling salesman problems (TSP) show th... Read More about An Investigation into the improvement of Local Minima of the Hopfield Network.

Neural networks in measurement and control (1995)
Journal Article
Armitage, A. (1995). Neural networks in measurement and control. Measurement and Control, 28(7), 208-215. https://doi.org/10.1177/002029409502800703

A brief overview of neural network is presented. Neural networks have certainly made an impact, and it is now at the stage of getting past the initial hype to see the sort of tasks that neural network are really suited to. There is no doubt that neur... Read More about Neural networks in measurement and control.
