Abstract: A system and method for providing Feature Group B or Feature Group D access to the public data network for effecting point of sale transactions such as credit card  authorization.    The  credit  card  authorization device  includes  a  modem  and  auto-dialing mechanism which is connected by a station line to an originating central office switch.  The originating central office switch  is  connected  via  Feature Group B or Feature Group  D  trunks  to  a  designated destination  central office including a stored program control (SPC) switch.          The destination central office is a functioning central office  connected  to  other  central  offices  by non-Feature  Group  trunks.  The  Feature  Group  trunks  are connected  by  the  switch  in  the destination central office to a designated line which is connected to a line side modem which is connected via the public data network to a host computer for effecting the credit card authorization.  The SPC switch at the destination central office converts the Feature Group number on the Feature Group  trunk  to  a line  side  number  for  the station containing the line side modem.  Common channel signaling  and  quick  start  or  ground  start  are preferably utilized to optimize speed.

Abstract: L'invention porte sur des procédés et systèmes permettant de déterminer des composantes cosinusoïdales (I) et sinusoïdales (Q) en vue de la modulation de signaux numériques dans des systèmes de télécommunications. Des modes de réalisations cités à titre d'exemple se rapportent à de telles déterminations réalisées à l'aide de techniques de traitement de signaux numériques qui permettent d'améliorer la précision des composantes tout en réduisant la capacité de mémoire des processeurs (par exemple des mémoires de processeurs de signaux numériques), nécessaire à cette tâche. Des informations de phase tirées d'échantillons de signaux donnent accès à une ou plusieurs tables contenant des valeurs de composantes ou une combinaison de valeurs de base de composantes et de valeurs de différence entre valeurs de base consécutives. Les informations de phase peuvent servir à dériver une valeur de déphasage qui s'ajoute à la valeur de base d'une composante pour en donner la valeur de sortie. Ces opérations ont pour effet de réduire la capacité de mémoire requise tout en maintenant une résolution élevée.

Title: Method and apparatus for encoding and formatting data representing a video program to provide multiple overlapping presentations of the video program
Inventor: KRAUSE EDWARD A
IPC: H04N7/173
Filed: 1998-01-21
Granted: 2006-07-11
Abstract: Selective video-on-demand access is provided to a virtually unlimited number of subscribers by partitioning the video program into an ordered sequence of N segments and providing the subscribers concurrent access to each of the N segments. A data stream representative of the video program is partitioned into N subsequences, each representative of one of the N segments. The data of each of the N subsequences is organized as an ordered sequence of elements. The elements of each of the N  subsequences are interleaved and the interleaved data stream is continuously transmitted over a video program distribution medium at a rate which renders the data representing each segment concurrently available to any subscriber having a receiver capable of selecting, assembling, and displaying the data of a particular segment.

Title: Battery capacity measurement circuit
Inventor: MASKE RUDOLPH J
IPC: G01R31/36
Filed: 1998-09-30
Granted: 2008-01-29
Abstract: An electronic circuit and a method for accurately measuring intermittent current pulses supplied by a storage battery to energize a load. In the preferred embodiment, an analog integrator accumulates current pulses in response to a voltage drop across a sense resistor that is connected in series between the storage battery and the load. The voltage drop is proportional to the flow of current from the battery through the load.  The output of the integrator is filtered with a low pass filter to block high frequency noise, and the output of the filter is coupled to an analog to digital (A/D) converter that transforms the filtered analog signal into a corresponding digital signal. The output of the A/D converter is supplied to a port of a processor. The processor provides a signal to actuate a reset switch coupled across the integrator. When closed at the end of each integration time period, this switch zeroes the output of the analog integrator. Additionally, the processor recalibrates the circuit at predefined time intervals to determine for leakage currents for improving the accuracy with which the measurement of the flow of current from the battery is determined. In the preferred embodiment, the processor samples the output of the A/D converter every 100 milliseconds. Typically, the calibration procedure is performed every 15 minutes (while the load is energized from an AC source). This measurement circuit is part of a battery management system that preferably also includes a charge circuit for recharging the battery.

Title: Method of pressure mapping for prediction of comfort in an automotive seat
Inventor: MILOSIC MARI C
IPC: B60N2/90
Filed: 1999-06-03
Granted: 2007-12-18
Abstract: A quantitative method of mapping of an automotive seat for pre;diction of seat comfort includes connecting a computer for storing and displaying pressure maps produced from a pressure mapping system. The pressure mapping system includes a map placed on the seat comprising an array of resistive elements connected to a data acquisition board and utilizing pressure mapping software. A force exerted on the mat changes the resistance of the elements which are sent to the data acquisition board and converted to an array of pressure values by the software to define a pressure map. A plurality of different pressure maps are generated by different forces exerted on the seat, normalized with a common reference pressure map and stored in memory. The normalized pressure map data is then averaged and processed through a comfort analysis or prediction step which compares the averaged pressure map to the reference pressure map. The results are displayed based on a ratio difference between the averaged pressure map and the reference pressure map to quantify seat comfort. The results are rated based on total pressure loading, percent pressure loading of specified delineated areas on the seat, percent point pressures and pressure map gradient loading.
