Abstract: The present invention provides an interactive integrated medical radiographic system comprising in combination a radiation source, an electronic detector including an analog to digital converter, a central control device including a CPU and a user interface a memory and a display device. The radiation source emits on command a radiation beam that is directed to pass through a target and impinge on the electronic radiation detector. The central control device communicates with both the memory, the radiation source, and the electronic detector, and is programmed to interact with an operator through the user interface and in response to input by the operator, and data stored in the memory, to initialize the detector, to set the radiation source for a desired exam, to retrieve from memory a sequence of steps representing actions by the operator required to perform said desired exam, and to sequentially guide the operator through said sequence of actions.

Abstract: A heat sensitive recording material comprising a recording layer formed on a substrate and containing at least one colourless or light-coloured colour former and at least one colour developer, the material being characterised in that the recording material gives a blue image, and the colour developer being at least one compound represented by the formula (1) wherein R1 is unsubstituted or substituted phenyl, naphthyl or C1-C20alkyl, X is a group of the formula (a), (b), or (c), A is unsubstituted or substituted phenylene, naphthylene or C1-C12alkylene, or is an unsubstituted or substituted heterocyclic group, B is a linking group of formula: —O—SO2—, —SO2—O—, —NH—SO2—, —SO2—NH—, —S—SO2—, —O—CO—, —O—CO—NH—, —NH—CO—, —NH—CO—O—, —S—CO—NH—, —S—CS—NH—, —CO—NH—SO2—, —

Abstract: The present invention is a navigational user interface for interactive television and, more specifically, for purchasing food products via the navigational user interface and a television. The invention uses an intuitive interactive interface for navigating through service options preferably offered by a cable television service. Services offered such as video on demand, purchasing delivery foods, restaurant selection, banking and community events is all navigated using the present invention.

Abstract: A device and method are provided for maintaining donor organs at reduced temperatures ex vivo, in particular while the organ is being implanted in the recipient, and until reperfusion of the organ. By maintaining the organs at reduced temperatures, the potential for external warming of the organ and ischemic injury is reduced and graft performance and survival is improved.

Abstract: A system for conveying a signal by optical fiber may include a converter for converting a radio frequency signal to an optical frequency signal, the converter having an interferometer modulator for providing a carrier suppressed optical frequency signal having a sideband modulated by the radio frequency signal, an optical amplifier for amplifying the modulated sideband before transmission on an optical fiber by an amount that is greater than or approximates the transmission loss in the system, a local oscillator, a coupler, and detector for converting (superheterodyning) the modulated sideband from the optical fiber to a predetermined intermediate radio frequency.

Abstract: A system for controlling train movement uses a distributed architecture. Wayside controllers receive signals from individual trains, including position information derived from a navigation system. The wayside controllers interface with a central train control network, and coordinate local train movement including the issuance of incremental authorities.

Abstract: Each access attempt transmitted to an authentication agency causes the agency to produce a request identifier unique to that request. The request identifier is transmitted back to the authentication code generator of the user initiating the access attempt, and to an authentication code generator in the agency. The agency also retrieves a user identifier from a database and sends it to its authentication code generator. Both the user's authentication code generator and the agency's authentication code generator independently combine, through identical or complementary transformations, the user identifier and the request identifier to form a user authentication code and an agency authentication code. The two authentication codes are presented by a comparator, which issues a permit signal only if the comparison indicates a match between the two authentication codes. The permit signal is transmitted to a transaction control device to permit the transaction to proceed.

Abstract: A thumb alignment grip guide is provided for attachment to a golf club handle. The thumb guide acts as a stop or barrier for preventing movement of the golfer's thumb during the golf swing, and allows a golfer to correctly grip the handle at the proper angular location with the lower hand for an accurate golf swing to have the club face contact the ball at the proper angle. The golfer grabs the handle and aligns and presses his or her thumb of the lower hand on the grip against the thumb guide. In one embodiment, the thumb barrier can be pivoted out of the way against the handle or removed when not in use.
