Abstract: The present invention provides a digit handling system and digit handling method for a subscriber terminal of a wireless telecommunications system, the subscriber terminal being arranged to have an item of telecommunications equipment connected thereto and being connectable to a central terminal of the wireless telecommunications system via a radio resource to enable a call to be routed between the item of telecommunications equipment and an exchange coupled to the central terminal. The digit handling system comprises a detector for detecting when the item of telecommunications equipment enters an off-hook state, a dial tone generator for generating a fake dial tone to the item of telecommunications equipment upon detection of the off-hook state, and a radio manager, responsive to detection of the off-hook state, for seeking acquisition of a communication channel of the radio resource over which to pass call data.

Abstract: A vehicular “black box” provides recording means by which driver action can be reviewed after an accident or collision, as well as indicating immediate vehicle disposition status to the driver. Using cameras (which may be very small), the disposition of the vehicle in its lane is determined by detecting the highway lines painted on the road.

Abstract: An agricultural vehicle is provided with means for continuously sensing the weight of an accumulated payload and a GPS navigation system (18). Weight and positional information, and optionally also sensed vehicle speed, are analysed in an analysis/display unit (14) and a map generated of e.g. weight/hectare. The principal application is an agricultural trailer with payload weight sensors (15), towed by a tractor with GPS and analysis systems. A map of yield of e.g. a root crop may be generated as the crop is harvested and continuously deposited into the trailer as it moves along.

Abstract: An optical device for displaying a large, two dimensional image is shown which utilizes a beam splitter having four faces upon which are mounted photosensor arrays. The photosensor arrays are mounted in a mosaic-like pattern upon each face with the pattern on one face differing from the pattern on the remaining three faces. Through this arranngement, standard photosensor arrays may be used to build a device that is capable of displaying a large image with no limitation on image side due to limitations on photosensor size.
