Abstract: La présente invention concerne un compteur d'électricité électronique qui, dans une réalisation, comprend une carte modem, ou une unité modem, couplée à un micro-ordinateur de mesure (20) et qui échange de l'information entre le compteur (10) et un ordinateur central (58). En utilisant des signaux fournis par le micro-ordinateur de mesure (20) et l'ordinateur central (58), le micro-ordinateur à modem (50) peut décider si l'échange d'information entre le compteur et l'ordinateur central (58) doit avoir lieu et à quel moment cette information devra être échangée. Dans une réalisation à titre d'exemple, l'unité modem (50) détecte des conditions variées dans le compteur et répond en échangeant de l'information avec l'ordinateur central (8) à un moment prévu ou prédéfini. L'unité modem présente deux états ou modes de fonctionnement de base. Ces deux états de fonctionnement sont quelquefois appelés le mode départ d'appel et le mode réponse d'appel. Le mode départ d'appel se rapporte au mode de l'unité lorsqu'une condition est réalisée dans le compteur (10) et que l'information est transmise à l'ordinateur central (58) à partir de l'unité modem (50) au moyen d'une ligne téléphonique. L'appel est mis en départ lorsque, par exemple, le compteur constate une panne d'électricité. Dans le mode réponse d'appel, l'ordinateur met en départ un appel vers le compteur. L'ordinateur central (58) peut alors transférer de l'information au compteur, par exemple un nouveau programme qui peut être stocké dans la mémoire de l'unité modem.

Filed: 1998-10-27
Abstract: In a communication system (100) where a remote unit is given a time offset for a base station (102) and hands off to the base station (102) if the remote unit (113) can acquire the base station within a time window surrounding the time offset, a remote unit {113) utilizes the time offset of each base station (supplied by a serving base station (101) via downlink communication signal (116}) and searches for neighboring base stations within the time window surrounding its PN offset.  The time window surrounding an individual base station's PN offset is allowed to vary depending upon whether the communication system (100) is time synchronized. In particular, a base station (101) supplies the remote unit {113) with an indication that the communication system (100) is operating in a synchronized or an unsynchronized mode, and the remote unit (i 13) varies the time window (search window) accordingly.
Patent CA-2311345-A1 (CA)
Inventor: HANNA EMMANUEL A
IPC: A47K17/02
Filed: 2000-06-13
Abstract: The present invention provides an ambulatory assistance device such as a grab bar or the like which pivots between a non-in-use and an in-use position. The pivoting of the device is assisted by a torsion member acting between the base member and the body. The torsion device is selected so as to retain the body in its non-in-use position when placed in that position. The weight of the pivoting body of the present invention overcomes the force generated by the torsion member when the body is placed in the in-use position so as to retain that orientation. Moreover, the torsion member acts to assist the user of the device in counteracting the weight of the pivoting body member when the body member is moved between the non-in- used position and the in-use position.

Inventor: FULLERTON LARRY W
IPC: G01S13/86
Filed: 1999-05-26
Abstract: A system and a method for distance measurement utilizes a radio system. The distance is measured by determining the time it takes a pulse train to travel from a first radio transceiver to a second radio transceiver and then from the second radio transceiver back to the first radio transceiver. The actual measurement is a two step process. In the first step, the distance is measured in coarse resolution, and in the second step, the distance is measured in fine resolution. A first pulse train is transmitted using a transmit time base from the first radio transceiver. The first pulse train is received at a second radio transceiver. The second radio transceiver synchronizes its time base with the first pulse train before transmitting a second pulse train back to the first radio transceiver, which then synchronizes a receive time base with the second pulse train. The time delay between the transmit time base and the receive time base can then be determined. The time delay indicates the total time of flight of the first and second pulse trains. The time delay comprises coarse and fine distance attributes. The coarse distance between the first and second radio transceivers is determined. The coarse distance represents the distance between the first and second radio transceivers in coarse resolution. An inphase (I) signal and a quadrature (Q) signal are produced from the time delay to determine the fine distance attribute. The fine distance indicates the distance between the first and second transceivers in fine resolution. The distance between the first and second radio transceivers is then determined from the coarse distance and the fine distance attributes.

Title: Electronic stacked assembly
Inventor: SCHWARTZ RICHARD F
IPC: H04B1/08
Filed: 2001-01-29
Abstract: A new physical design for electronic devices (100) comprises a multi-layer stacked assembly (104-110) of a plurality of pan-shaped conductive units that form the layers of the assembly. Each unit is preferably formed from a single sheet of metal into which electronic components, such as an antenna array (208) or a filter array (314) of a transceiver, have been stamped, cut, or etched, and which is then bent around its periphery to form a pan shape. The pans are oriented to face the same direction, are stacked one on top of another, and are fixedly attached to each other by weld, solder, or adhesive. The electrical components defined by the different units are electrically interconnected in a connectorless manner, preferably by flanges (122, 124) formed in the same sheets of metal as the units themselves and extending between the units. Adjacent units in the stack define electromagnetically isolated chambers, e.g., for the filter array. Some layers perform double duty, e.g., a layer (106) that forms a part of the chamber that houses the filter array also acts as a reflector plane for the antenna array.

Title: Libraries of oligomers labelled with different tags
Inventor: SOUTHERN EDWIN MELLOR
IPC: C12Q1/6872
Filed: 1999-05-17
Abstract: A method of making a set of labelled compounds by the use of a preferably particulate support, comprises dividing the support into lots, performing a different chemical reaction on each lot of the support, e.g. to couple a chemical moiety to that lot of the support, tagging a fraction of each lot of the support with a different label, and combining the said lots of the support. The steps are repeated several times, preferably to build up oligomer molecules carrying labels which identify the nature and position of a monomer unit of the oligomer, and which are releasable from the support. Preferred labels, which are releasable from the compounds by cleavage to provide charged groups for analysis by mass spectrometry, are groups of the trityl (trimethylphenyl) family. Also claimed are libraries of these labels and their use in assays and nucleic acid analysis methods.

Title: Transmission system
Inventor: KANNO YOSHIHISA
IPC: B60K23/00
Filed: 2001-04-02
Abstract: A series of multifunction controls are provided to operate a hydrostatic automatic transmission and subtransmission wherein one of running ranges is switched to another by a sub-transmission lever. An automatic speed change mode is switched to or from a stepping speed change mode by a mode map switch, and when the stepping speed change mode is selected, manual speed change is performed by a shift switch. The shift switch and the mode map switch are configured as a common switch. The common switch is used as the shift switch during running of the vehicle, and the shift switch is changed into the mode map switch when the shift switch 28 is depressed only under the condition that the vehicle is stopped and the running range selected by the sub-transmission is located at the neutral (N) or that the vehicle is stopped and the brake switch is turned on. When the shift switch is depressed, the function of the shift switch is changed into the function of the mode map switch, and the speed change mode is switched by one stage each time the mode map switch is depressed. This control arrangement is cost effective and convenient to us.
