Abstract: A circuit tracer for determinating the location of a conductor, such as a wire, which is either an open or closed circuit, and which may lie underground. The tracer includes a transmitter which is connected to the conductor, a hand-held probe, and a re-ceiver which is connected to the probe. The probe has three different sensors:  an electric field sensor (62), primarily for locating the terminus of an open-ended conductor or for distinguishing such a wire in a bundled cable or wires; a differential electric field sensor (64, 66), for determining the direction to and location of an open-ended conductor located above ground; and an inductive sensor (68) for determining the direction to and location of a current-carrying conductor, including an open-ended conductor ly-ing below ground. A switch selectively provides the output from one of the sensors to the receiver unit, which determines the mag-nitude of any signal based upon the direction the probe is pointing. By swinging the probe back and forth, and observing the re-ceived signal, the direction to and location of the conductor may be determined.

Abstract: An apparatus and a process for drying a suspension of a finely divided particulate solid material to produce the solid material in a substantially dry and unagglomerated form.  The apparatus comprises a grinding chamber (1) containing a particulate grinding medium (12), means (21) for introducing a suspension of the particulate solid material into the grinding chamber (1) and an impeller (8, 9) rotating in the grinding chamber (1).  The grinding chamber (1) has a perforated base (3) through which a heated gas is introduced to provide an upward flow of gas through the grinding chamber (1) and through the grinding medium (12).  As the particulate solid material is dried, fine particles of the material are carried upwards in the upflow of gas through the grinding chamber (1) and may then be classified by classifying means (25) which separate the substantially dry product into a relatively fine fraction and a relatively coarse fraction.  Downstream of the grinding chamber and of the classifying means (25), if provided, are filter means which separate the solid particles from the suspended gas.  The filter means may comprise one or more cyclones (30) and/or a bag filter assembly

Abstract: In a radio receiver for receiving vestigial sideband (VSB) signals including symbol codes descriptive of digital signals, HDTV signals being exemplary of such VSB signals, a tuner provides for selecting one of channels at different locations in a frequency band used for transmitting such VSB signals. The tuner also includes mixers for performing plural conversion of the selected channel to a final intermediate-frequency signal, which is digitized by an analog-to-digital converter. A phase tracker, operative on narrow-bandpass filtered portions of the digitized final intermediate-frequency signal centering on its carrier frequency, suppresses an imaginary portion of the final intermediate-frequency signal, arising from multipath distortion or from phase incoherency in local oscillations used during frequency conversion. A digital controlled oscillator in the phase tracker supplies digital descriptions of the carrier wave for the final intermediate-frequency signal to a synchronous detector, which synchronous detector detects the real portion of the digitized final intermediate-frequency signal in accordance with those digital descriptions of the carrier wave. A pair of all-pass digital filters, which exhibit a constant .pi./2 difference in phase response for the digitized bandpass signals and are designed based on Jacobian elliptic functions as described by C. M. Rader, are used in the phase tracker for generating the real and imaginary portions of the digitized final intermediate-frequency signal.

Title: Method and apparatus for efficient addressing of dram in a video decompression processor
Inventor: HOOGENBOOM CHRIS
IPC: H04N7/50
Filed: 1995-08-02
Granted: 2001-12-04
Abstract: Pixel data is stored and subsequently read from a random access memory of a video decompression processor in a manner that reduces the number of times different rows of the RAM must be addressed in order to retrieve portions of the pixel data therefrom.  Pixel data from a video frame is stored in the RAM as a plurality of pages.  Each page substantially fills a different row of the RAM and corresponds to a different section of the video frame.  A motion vector is decoded to determine the location of a prediction area within the video frame.  In the event that the prediction area encompasses more than one of the pages of the video frame, the pixel data is retrieved one page at a time, minimizing the number of row changes required when addressing the RAM to retrieve the data.

Abstract: La présente invention s'applique à la capote d'un cabriolet (16) dont des vérins hydrauliques (29) assurent la manoeuvre entre une position totalement dépliée et une position repliée. Les extrémités des vérins sont raccordées (26, 28) aux orifices (60, 60') d'une pompe hydraulique (36) réversible située dans un logement (34) oblong. La pompe est équipée d'un réservoir (42) à l'extrémité opposée aux orifices, le carter de pompe (42) assurant la séparation entre la pompe et le réservoir. Le carter de pompe (42) abrite deux circuits de fluide (60-88, 60'-88') raccordant la pompe (36) aux extrémités des vérins (29). Chaque circuit comporte un dispositif de verrouillage de fin de cycle hydraulique (78, 80, 98, et 78', 80', 98') consistant en une soupape fermée au repos (78, 80 et 78', 80') et un actionneur de soupape (90 et 90'). Les soupapes des circuits (78, 80 et 78', 80') s'ouvrent dans un sens ou dans l'autre sous la pression de la pompe pour mettre sous pression l'une ou l'autre des extrémités de vérins (29) suivant qu'il s'agit de déplier ou de replier la capote (16). Lorsque la pompe (36) arrête de fonctionner, les soupapes ouvertes (78, 80 et 78', 80') se referment, ce qui empêche le fluide de refluer par le circuit vers la pompe (36). De la sorte, le mouvement de capote (16) est hydrauliquement verrouillé en position totalement dépliée ou en position repliée pour faciliter les opérations de fermeture de la capote ou de rangement de la capote derrière les sièges arrières. Une rainure (83) ménagée dans le siège de soupape, assure un écoulement de fuite faisant office de dérivation lorsque la soupape est fermée. Cette dérivation permet de détendre lentement dans une proportion déterminée la pression hydraulique au niveau de l'actionneur (29), une fois qu'un délai suffisant s'est écoulé, délai pendant lequel il a été possible de fermer la capote ou de la ranger derrière les sièges arrières. Dans le carter de pompe (42), une dérivation manuelle (120-140) de la pompe permet de déprimer les deux circuits vers le réservoir (40) pour qu'on puisse manoeuvrer à la main la capote en dehors du fonctionnement de la pompe. Le carter de pompe abrite des dispositifs à soupape d'appoint (150-156 et 150'-156') destinés à prendre en compte le différentiel de déplacement à l'intérieur des vérins (29).

Abstract: A system for delivering packetized data in a network dynamically assigns a unique address to a mobile unit, allocates bandwidth within a wireless link by a token scheme and provides forward error correction for the packet. The system has a means for wirelessly transporting the packets between a base station and an end point which is responsive to a link cell for linking the base station and the end point. The link cell contains a header and a body. The header in turn contains a forward error correction code, a radioport id and a token. The forward error correction code provides error detection and error correction that relies solely on a one-way communication of data bits from a sender to a receiver. The radioport id is a logical id assigned such that each radio-port in a vicinity has a unique id. The token enables the wireless transportation over a selected channel of the packets between the base station and the end point. The token is utilized to allocate the selected channel from a plurality of channels. A method is also described for delivering packetized data between an endpoint and a base station.

Title: Dispositif de detection sans contact et de signalisation par courants intra-corporels induits par une source exterieure
Inventor: ALLPORT DAVID
IPC: G06F3/044
Filed: 1996-05-01
Granted: 2002-07-09
Abstract: Un dispositif sans fil comporte un émetteur (14) et un récepteur (22) couplés par le biais d'un utilisateur (10) et de la terre (11) d'une pièce. L'émetteur génère des signaux à basse fréquence et de faible puissance qui, par couplage capacitif, traversent ou quittent, en tant que courants de déplacement (13), le corps d'un utilisateur. La terre partagée de la pièce fournit au courant la voie de retour. L'émetteur comporte deux électrodes, intérieure (18) et extérieure, ainsi qu'un générateur de signaux (16) émettant des signaux modulés qui varient en fonction de la tension appliquée entre les électrodes. L'électrode intérieure est étroitement couplée, d'une manière capacitive, au corps de l'utilisateur de sorte que le champ "quasiment électrostatique" né du potentiel de l'électrode est à l'origine d'un courant de déplacement se dirigeant vers le corps de l'utilisateur. L'électrode extérieure est ainsi orientée que le couplage qu'elle forme avec la terre de la pièce est plus fort que celui qui est formé avec l'électrode intérieure de sorte que la terre de la pièce agit comme voie de retour pour le courant émanant du récepteur. Ce dernier comporte, de façon similaire, une paire d'électrodes (24, 26) ainsi qu'un détecteur/démodulateur (28) qui capture et poursuit le signal transmis. Une des électrodes (24) du récepteur est étroitement couplée, d'une manière capacitive, au corps de l'utilisateur de sorte que le courant de déplacement quittant le corps se dirige vers elle. Le courant circule alors à travers les circuits du détecteur en direction de l'autre électrode (26), laquelle est couplée de manière asymétrique et capacitive à la terre de la pièce, pour fermer le chemin de courant. Les circuits du détecteur détectent le courant et fonctionnent de manière classique pour récupérer l'information transmise. D'autres utilisateurs peuvent être porteurs d'un ou plusieurs récepteurs ou bien ces derniers peuvent se trouver à des emplacements fixes dans une pièce tandis que la voie de retour peut être le fait d'une combinaison terre aérienne - terre terrestre. De ce fait, il n'est pas nécessaire que l'utilisateur soit en contact physique avec les récepteurs pour leur faire passer une information. Selon une variante, les récepteurs peuvent être montés en réseau sur un écran d'ordinateur, l'émetteur se trouvant alors dans le clavier.
