Abstract: A sensing arrangement (11) for sensing objects at a plurality of sensing sites (64) is described herein. In one embodiment the arrangement comprises: an imaging device (60) having an array of light-detecting elements; a light guide arrangement (62) extending from the sensing sites (64) to the imaging device (60); a mount (79) for maintaining the light guide arrangement (62) and the imaging device (60) in a fixed spatial relation so that each sensing site (64) illuminates a zone (60a,b) of different elements on the array; and a processor (72), in communication with the imaging device (60), for analyzing image data captured by each zone. A method of sensing an object is also described herein.

Abstract: A note skew detector, for use in a note transport mechanism of an Automated teller Machine (ATM) is described. The detector comprises a light source and a single optical sensor, optically coupled via a pair of optical wave-guides arranged to have an air gap there between so as to provide a note transport path between the said wave-guides. The wave-guides are further arranged to provide a first optical path and a second, distinct, optical path between said light source and said sensor.

Abstract: A sensing arrangement (12) is described. The arrangement comprises: a moveable object (80) including a plurality of marker portions (112) disposed in a calibrated configuration, each marker portion (112) being capable of emitting light in response to stimulation. The arrangement also includes a light source (42) directed towards the marker portions (112) and for causing light emission therefrom. An imaging device (44) is directed towards the marker portions (112) and includes an array of light-detecting elements for sensing light emitted from the marker portions (112) to generate image data. A processor (52), in communication with the imaging device (44), analyses image data received from the imaging device (44) to determine the location of the moveable object (80) based on the calibrated configuration.

Abstract: An optical detector is disclosed, which is adapted to measure the opacity of media. The detector comprises a light means and a light sensor, arranged so as to have a media path there between. The light source has a drive means, which is actively adjustable, during use, for detecting media of different opacities, so as to maintain a substantially constant sensor output.
