Title: Method for determining proximity of devices in a wireless network
Inventor: MEUNIER JEAN-LUC
IPC: H04W64/00
Filed: 2004-11-15
Granted: 2009-05-12
Abstract: In a wireless network, two or more devices can determine how close they ar e from one another in a peer-to-peer way, by exchanging the network characteristics they observe in real time. A method for determining device proximity in a wireless network, includes characterizing at a first device any detected wireless network radio signals; receiving any broadcast network characteristics from at least one other device on the network; comparing the first device network characteristics with the received network characteristics from the at least one other device on the network; i f the network characteristics are within a predetermined relationship, the first device and the at least one other device are in proximity with one another. Network characteristics may include signal strength, noise level and MAC address of the transmitting device. The method eliminates the need to calibrate WiFi signal strength as a function of location in a particular area.

Granted: 2012-04-24
Abstract: Un système de coupure pour faible volume d'eau (A) détermine si un liquide (W) à l'intérieur d'une chaudière ou autre récipient chute en deçà d'un niveau prédéterminé dans le récipient. Un générateur de signaux applique un signal dans le récipient, de sorte que le signal est présent pour la détection au niveau prédéterminé, lorsqu'une sonde est fournie pour détecter la présence du signal, advenant un niveau d'eau prédéterminé. Une commande , qui comprend un microcontrôleur, réagit à la sonde pour assurer une fonction de commande, en réponse à la condition du signal détecté par la sonde, et ainsi pour déterminer si le volume de l'eau a chuté en dessous du niveau prédéterminé. La fonction peut produire une alarme ou la coupure du chauffage de la chaudière. Des fonctions d'autovérification et de retardement sont aussi incluses. Il est prévu que la commande compense les variations de conductivité électrique de l'eau à travers laquelle le signal de la sonde est envoyé, qui comprend des circuits pour régler la vaste plage des degrés de pureté possibles. Il est prévu que le système de coupure pour faible volume d'eau tolère des défaillances, quel que soit le degré de pureté auquel ce système est réglé pour fonctionner.

Title: Tensioner
Inventor: SERKH ALEXANDER
IPC: F16H1/00
Filed: 2003-10-01
Granted: 2009-04-14
Abstract: A motorized tensioner (100) that is controllable for adjusting a belt tension. The tensioner (100) comprises a tensioner arm (101) and a spring (109). One end of the spring (109) is connected to a moveable member that is connected to a gearbox (104) driven by an electric motor (103), whereby a spring position is adjustable. The other spring (109) end is connected to a damping mechanism (108), which is in turn engaged with the tensioner arm (101). The motor (103) and gearbox (104) position the moveable member, and thereby a spring (109) end, according to a control signal received from a controller. The spring (109) end position determines the spring (109) force and thereby the belt tension in the system. The damping mechanism frictionally interacts with a tensioner body (102) to damp oscillatory movements of the tensioner arm (101).

Title: Hierarchical coding with multiple antennas in a wireless communication system
Inventor: MANTRAVADI ASHOK
IPC: H04L5/04
Filed: 2004-09-27
Granted: 2012-02-21
Abstract: Techniques are provided for performing hierarchical coding in a multi-antenna communication system (e.g., a SIMO, MISO, or MIMO system). At a transmitter, a base stream and an enhancement stream are coded and modulated separately to obtain first and second data symbol streams, respectively. The first data symbol stream is processed in accordance with a first spatial processing scheme (e.g., a transmit diversity or a spatial multiplexing scheme) to obtain a first set of symbol substreams. The second data symbol stream is processed in accordance with a second spatial processing scheme (e.g., transmit diversity or spatial multiplexing) to obtain a second set of symbol substreams. The first set of symbol substreams is combined (e.g., using time division multiplexing or superposition) with the second set of symbol substreams to obtain multiple transmit symbol streams for transmission from multiple transmit antennas. A receiver performs complementary processing to recover the base stream and enhancement stream.

Title: Exercise garment
Inventor: SEMBA TAKAYUKI
IPC: A41B1/00
Filed: 2006-12-26
Granted: 2012-11-06
Abstract: There is provided an exercise garment according to which the exercise performance in various types of exercise accompanied by rotation of the trunk and movement of the arms can be sufficiently improved.   With the exercise garment 1, when the exercise garment 1 is being worn, tightening forces due to first tightening portions 21 act on the scapulae and the scapala-surrounding muscle groups, so that the scapulae and the scapula-surrounding muscle groups are supported such that the extent of mobility of the scapulae is broadened when the wearer carries out rotation of the trunk or movement of the arms. Moreover, the tightening force due to one of the first tightening portions 21 is transmitted to the other first tightening portion 21 via second tightening portions 22. As a result, movement of one scapula linked to the movement of the other scapula is promoted, and hence the extent of mobility of the scapulae is further broadened. Consequently, with the exercise garment 1, the flexibility around the shoulders during exercise in which the left and right shoulders are working together can be effectively increased, and hence an improvement in performance in various types of exercise accompanied by rotation of the trunk and movement of the arms is achieved.

Title: Dosage forms of risedronate
Inventor: DANSEREAU RICHARD JOHN
IPC: A61K31/663
Filed: 2005-11-23
Granted: 2009-10-13
Abstract: Oral dosage forms of a risedronate comprised of a safe and effective amount of a pharmaceutical composition com-prising risedronate, a chelating agent, and, means for effecting delayed release of the risedronate and the chelating agent in the small intestine provide immediate release of the pharmaceutical composition to the small intestine of the mammal subject and pharmaceu-tically effective absorption of the bisphosphonate with or without food or beverages. The present invention substantially alleviates the interaction between risedronate and food or beverages, which interaction results in the bisphosponate active ingredient not being available for absorption. The resulting oral dosage form may thus be taken with or without food. Further, the present invention effects delivery of risedronate and the chelating agent to the small intestine, substantially alleviating the upper GI irritation associ-ated with bisphosponate therapies. These benefits simplify previously complex treatment regimens and can lead to increased patient compliance with bisphospanate therapies.
