Title: Dispensing system and method with radio frequency customer identification
Inventor: NADKARNI GEETA B
IPC: G06Q30/06
Filed: 1996-12-18
Abstract: A system and method for providing a fuel dispenser (14) with radio frequency customer identification capabilities. The system and method determines whether a transponder (23, 25) containing customer identification data is within range of a dispenser (14) that requires activation by the customer to initiate a transaction and has an associated reader (20) for emitting radio frequency signals and receiving customer identification data from the transponder (23, 25) responsive to the emitted radio frequency signals. When the transponder (23, 25) is within range of the dispenser, an in-range indication is provided to the customer. Upon activation of the dispenser (14) following a determination that the transponder (23, 25) is within range, the customer identification data received by the reader (20) is associated with a transaction at the activated dispenser. The transaction at the activated dispenser (14) is then permitted and charged to the customer according to the customer identification data.

Title: Transmit sequencing
Inventor: HORTON ROBERT R
IPC: H04J1/06
Filed: 1997-04-17
Abstract: A method and apparatus for initializing a radio transmission apparatus comprising a voltage control oscillator, a phase lock loop, and a power amplifier is disclosed so as to avoid generating unwanted interference in neighboring radio channels. First, the voltage control oscillator is enabled and the phase locked loop is switched from a narrow band mode to a wide bandwidth mode to give faster settling time and reduced overshoot. The power amplifier is then smoothly camped up to a final power level. Finally, the phase locked loop is switched from the wide bandwidth mode to the narrow bandwidth mode after the power amplifier has substantially reached the final power level.

Title: Recording device having short data writing time
Inventor: MATSUMOTO TOSHIO
IPC: G06F12/14
Filed: 1992-04-10
Abstract: A recording device which improves a response time to write data by reporting to a host computer the completion of writing operation prior to the completion of writing redundancy data.  Data writing command information from the host computer is stored in a command/status memory backed up by a power source in an array controller, and the completion of writing operation is reported to the host computer at the time of the completion of writing updated data prior to the completion of writing redundancy data.  Redundancy data is written as a background process.  If redundancy data could not be written due to any abnormality of the power source or the like, such redundancy data may be generated from the data in other disk units of the same redundancy group in accordance with writing command information stored in the command/status memory, thereby completing the writing of redundancy data.

Title: Recepteur a diversite
Inventor: DELPRAT MARC
IPC: H04B7/08
Filed: 1999-04-07
Abstract: Pour améliorer les performances des récepteurs à diversité de l'état de la technique, on prévoit de réaliser deux voies de traitement. Une première voie de traitement comporte un mode de traitement de diversité, tandis qu'une deuxième voie de traitement comporte un deuxième mode de traitement de diversité. On utilise les signaux délivrés par les deux voies de traitement, pour les combiner ensuite dans un circuit de combinaison du type à évaluation de vraisemblance. Par exemple, une des deux voies comporte un traitement de focalisation d'antennes, alors que l'autre voie comporte un traitement de combinaison. Dans les deux cas, les deux voies de traitement reçoivent les signaux en provenance des deux antennes. On montre qu'en agissant ainsi, on cumule efficacement les améliorations apportées alternativement par l'une ou l'autre de ces solutions.

Title: Device and method for analyzing a biologic sample
Inventor: LEA PETER
IPC: G01N1/10
Filed: 1999-11-12
Abstract: A device for separating fluid from a biologic sample when the sample has a fluid and non-fluid component. The device is a point-of-care device through which data may be electronically collected and electronically transmitted for further evaluation. A method for separating fluid from a biologic sample is provided wherein the method comprises the step of bringing the fluid sample in fluid contact with the microspheres such that the fluid component moves by capillary action between the microspheres along capillary channels formed by the spaces between the spheres and leaving, for example, a cellular fraction behind. In the device of the present invention, the step of separating the fluid may be combined with other assay techniques for detecting and/or measuring one or more analytes which may be present in the fluid sample such as immunoassays and chromatographic assays. These may be further combined with groups of microspheres for use in the analyte detection step as well as the separation step whereby the microspheres act as labels for the analyte or as a source of label for the analyte.

Title: Dynamic selection of media streams for display
Inventor: PRETTY RUSSELL W
IPC: H04M11/00
Filed: 1998-03-11
Abstract: One or more streams from a number of real-time video streams available to be transmitted across a communications network, are selected for display on respective terminals of a first, and at least one other user. First, a policy of the first user for making the selection, is determined, the policy containing conditions to be evaluated, selectable by the first user. Then, which streams to select for the first user is determined dynacamically by evaluating the current conditions according to the first user's policy. Only the selected streams are passed for display on the terminal of the first user, independently of selections made for passing to the other users. Dynamic selection from multiple streams enables the user to concentrate on the content not the form of presentation. Individual control of what is displayed, independent of what other users see, enables tailoring to suit resources and user priorities. Both enable larger video conferences to be handled more easily.

Title: Honeycomb light trap for projector
Inventor: RODRIGUEZ ERNESTO M JR
IPC: G03B21/16
Filed: 1998-06-18
Abstract: A light trap for a projector, such as an integrated LCD projector, is provided for placement in ventilation channels to prevent escape of light through the channels while allowing free flow of cooling fluid through the channels. The light trap is constructed of material having a honeycomb-like structure, with conduits in the light trap being preferably disposed obliquely between the light source and the duct opening. The light trap may be coated or treated to increase absorption of visible and infrared radiation. A light trap according to this invention not only prevents escape of extraneous light from the projector's ventilation openings, but it assists in controlling the heat load generated by the light source, and it provides less resistance to air flow than does a louvered panel that is typically used to cover a ventilation opening in a projector thus reducing the amount of noise associated with the ventilation system.
