Title: Commande de la largeur de bande dynamique dans un stimulateur cardiaque medical implantable
Inventor: BRULS ANNETTE
IPC: A61N1/38
Filed: 1998-04-13
Abstract: Cette invention se rapporte à un dispositif médical implantable (100) qui sert à stimuler électriquement les battements du coeur et qui comprend à cet effet un circuit de détection (218) destiné à détecter l'activité électrique du coeur. Ce circuit de détection (218) comprend un filtre passe-bande (215) ayant une réponse en fréquence ajustable. La réponse en fréquence peut être ajustée de façon répétée après l'implantation du dispositif médical et elle est de préférence ajustée lors de la détection d'une perte du rythme sinusal normal (NSR) dans les oreillettes. La perte du rythme NSR indique souvent une fibrillation auriculaire (AF) et la réponse en fréquence du filtre est alors ajustée pour augmenter la sensibilité du circuit de détection à l'activité électrique cardiaque qui est typique pendant la phase AF. Ledit dispositif médical est étalonné pendant l'implantation ou lors des visites ultérieures du médecin, à l'aide d'un dispositif d'étalonnage extérieur au corps. L'activité électrique cardiaque sous la forme d'un électrogramme est transmise du dispositif médical au dispositif d'étalonnage externe. L'électrogramme transmis contient de préférences à la fois les rythmes NSR et AF. Le dispositif d'étalonnage calcule (440, 410) deux groupes de coefficients du filtre, un premier groupe (440) pour une sensibilité accrue du filtre pendant la phase MSR et l'autre groupe (490) pour une sensibilité accrue pendant la phase AF. Les coefficients sont transmis au dispositif médical, lequel utilise le groupe approprié de coefficients pour augmenter la réponse en fréquence du filtre à la fois pendant la phase MSR et la phase AF.

Abstract: A method and search apparatus for searching a database of records organizes results of the search into a set of most relevant categories enabling a user to obtain with a few mouse clicks only those records that are most relevant. In response to a search instruction from the user, the search apparatus searches the database, which can include Internet records and premium content records, to generate a search result list corresponding to a selected set of the records. The search apparatus processes the search result list to dynamically create a set of search result categories. Each search result category is associated with a subset of the records within the search result list having one or more common characteristics. The categories can be displayed as a plurality of folders on the user's display. For the foregoing categorization method and apparatus to work, each record within the database is classified according to various meta-data attributes (e.g., subject, type, source, and language characteristics). Because such a task is too much to do manually, substantially all of the records are automatically classified by a classification system into the proper categories. The classification system automatically determines the various meta-data attributes when such attributes are not editorially available from source.

Title: Synchronization symbol structure using ofdm based transmission method
Inventor: BOEHNKE RALF
IPC: H04L7/08
Filed: 1999-12-06
Abstract: The present invention proposes a method for generating synchronization bursts for OFDM transmission systems. The symbols of a predefined symbol sequence are mapped according to a predefined mapping scheme on subcarriers of the OFDM systems by a mapping unit (2), wherein the symbols of the predefined symbol sequence represent subcarriers of the OFDM system with nonzero amplitudes. A  synchronization burst is generated by a inverse fast Fourier transforming unit (3) transforming the subcarriers of the OFDM system mapped to said predefined symbol sequence. The mapping (2) of the symbols of the predefined symbol sequence is set such that the resulting time domain signal of the synchronization burst represents a periodic nature. According to the invention the predefined symbol sequence is set such that the envelope fluctuation of the time domain signal of the synchronization burst is minimized.   Therefore advantageous symbol sequences reducing said the envelope fluctuation of the time domain signal are proposed.

Title: Watch dog timer system
Inventor: YAMASHITA ATSUYA
IPC: G06F11/28
Filed: 1999-12-21
Abstract: The invention provides a watch dog timer system which has an abnormality checking function of a high degree of reliability. In the watch dog timer system, abnormality of a computer system is detected as a variation of a value allocated in accordance with an execution condition of a program. To this end, a register receives execution state data defined in accordance with an execution condition of the program from a processor or CPU of the computer system and stores the execution state data before a counter of the watch dog timer system overflows. A comparator compares the execution condition data stored in the register and state sequence data indicative of a state sequence of the program stored in a ROM in advance with each other and generates a reset signal for resetting the computer system when the comparison reveals incoincidence.

Abstract: A suit having a lining and a slipover, and an active part arranged between the same. The active part is at least partially constructed of a layer which faces the body and of a layer which faces away from the body. Both layers are made of a liquid-tight, slightly stretchable textile material and are connected to one another at connection points by gluing, heat sealing or by sewing to form cavities.  The cavities are filled with a liquid through valves. Connecting parts which transfer tensile stress are provided in areas between the cavities. This builds up a compensating pressure which is proportional to the acceleration acting in the momentary and local direction, on the body parts under the suit and thus relieves a pilot's body from the effects of such accelerations. The suit is closed by zip fasteners, and is fitted to the body of the wearer by means of hook-and-loop fasteners and is tightened by using zip fasteners or a fluidic tightening device.

Title: Anti-theft system for disabling a vehicle engine
Inventor: JOHNSON RICHARD T
IPC: B60R25/04
Filed: 1998-09-17
Abstract: An anti-theft system disables a vehicle engine upon detection of an unauthorized vehicle start-up. A fob transmitter sends a coded frequency signal that is received to arm the anti-theft system. When armed, the system monitors whether the engine is running using a combination of vibration detection, voltage fluctuations in the battery voltage and the actual battery voltage. In the event of an unauthorized start-up, the system opens a switch to disconnect the battery and closes a switch to connect the alternator to ground through the resistor. In order to prevent a vehicle from being jump started by using a second battery, the system resets the connection of the alternator to ground at periodic intervals thereby repeatedly testing for the presence of the second battery and cause the engine to stall after the second battery is disconnected. A driver entry detection portion of the system determines whether someone has entered the vehicle, and issues a chirp signal to notify the occupant that the system is armed. An algorithm determines whether the battery voltage has reached a minimum state of charge for reliably starting the vehicle, and also disconnects the battery once the minimum level has been reached.

Title: Viterbi decoding using single-wrong-turn correction
Inventor: ALLPRESS STEPHEN ALAN
IPC: H03M13/41
Filed: 2000-05-19
Abstract: A recursive, single-wrong-turn (SWT) decoding method and Viterbi decoder which requires no additional circuitry or processing to keep track of a running list of the L best paths. If the most likely (ML) path fails frame quality metric tests, a search is made through a trellis using an existing survivor (trace back) information stored in a survivor (trace back) memory. An iteration in the recursive algorithm includes tracing back along the ML path to a particular stage, then deviating from the ML path and following the survivor information along that new deviant path, and finally checking the fully decoded frame to see if the frame quality metrics are acceptable for the frame. These same trace back steps can be performed for every stage in the trellis, deviating from a different stage on the ML path each time. A recursive, single-wrong-turn (SWT) decoding method and Viterbi decoder which exceed the performance of the general Viterbi algorithm and the various conventional list Viterbi decoders and which is much less computationally and physical complex.
