Abstract: A compact system for determining the presence and speed of an object/vehicle, and its application for Red Light Camera photo-enforcement is disclosed. The disclosed system uses accurate timing, laser radiation in the form of optical pulses, and the scattering effect of optical pulses from the road or vehicle surface to determine the presence of a vehicle, and estimate its speed. The system can determine whether an object/vehicle is present at a specific location, estimate its height, and in the case that the object/vehicle is moving, the system can estimate its speed. Combining the disclosed technology with commercially available digital recording techniques and equipment, a traffic photo-enforcement system can be constructed. The system is capable of monitoring traffic in an intersection/highway, measure vehicle speed, identify potential traffic violations, and trigger a visual recording device such as a camera or video system for documenting a violation.

Abstract: A system of lasers and detectors to detect the presence of objects and determine their speed is disclosed. The system comprises of a pair of lasers and a pair of detectors focused through a single lens. An electronic board that accompanies the lasers and detectors is used to provide the logic and decision making mechanism. Data collected and processed by the system yields such information as whether an object is present, whether is stationary or is moving, and subsequent speed information. The described system is also capable if desired of providing additional information concerning the characteristics of the moving object such as its profile and length, and indication of a traffic violation.

Abstract: Identification and contact information is captured and verified for dissemination. Electronic scals that identify an originator or author of an electronic message or document are inserted in the message or document. The seal forms an identification card for the originator or author based upon the verified contact information. A recipient or viewer of the message or document can view, in the message or document, the embedded seal that comprises a graphic and associated text. A network hyperlink reference from the seal to a server displays a seal verification page. The seal verification page comprises contact information for the originator or author, and other details such as those relating specifically to the message or document. The verified contact information is also used to provide a secure directory of contact information and a facility for printing business cards.

Abstract: A radio frequency (RF) transponder (RF tag) is proposed, where a high dielectric constant material is used in operative cooperation with a tag antenna so that the distance of the tag antenna from conducting or absorbing surfaces may be reduced, and so the tag dimensions may be reduced.

Abstract: A mobile communications network comprises a PCN network (60-64) including a plurality of radio cells under the jurisdiction of an MSC (mobile-services switching center). One or more of said cells comprise a fixed base (60, 61) for a mobile subscriber (71). Location information regarding the fixed bases being stored in a fixed location register (FLR). When the mobile subscriber roams into such a fixed base location (60, 61) a respective service type is provided. In particular, the fixed base may be a business site (60) with a PABX network. When the mobile subscriber roams into the business site, calls involving him are routed via the PCN network or rather the base station controller (BSC) thereof, which is intelligent in that it has MSC functionality located thereat. Thus a mobile phone can act as a desk phone, with all the same services provided, whilst the mobile subscriber is within the business fixed base.

Abstract: An asynchronous temporal neural processing element. The processing element is useful in solving problems from the class of temporal signal processing problems and is modeled closely on the sub-cellular biology and electrophysiology of neurons having chemical synapses.
