Title: Procede et appareil servant a polir des extenseurs chirurgicaux
Inventor: FRANTZEN JOHN J
IPC: A61F2/82
Filed: 1998-06-05
Granted: 2007-06-26
Abstract: L'invention concerne un procédé servant à polir des extenseurs chirurgicaux expansibles radialement, dans lequel un milieu abrasif fluide (M) s'écoule sur des surfaces de l'extenseur (10), provoquant un polissage et un profilage des surfaces de l'extenseur (10). L'extenseur (10) est temporairement prévu avec des extrémités de support (20) cylindriques qui ne sont pas expansibles radialement, de façon à permettre de soutenir l'extenseur (10) au cours du procédé de polissage. Un dispositif (100) de polissage intérieur est prévu, lequel contient des chambres (135) cylindriques conçues pour recevoir un extenseur (10). Le milieu abrasif fluide (M) s'écoule ensuite dans des orifices (108) situés dans le dispositif (100) qui mènent aux chambres (135) cylindriques, et de façon adjacente aux surfaces du diamètre interne de l'extenseur (10). On polit les surfaces de l'extenseur (10) qui forment le diamètre extérieur en plaçant l'extenseur (10) à l'intérieur d'un dispositif (200) de polissage extérieur présentant un évidement (220) cylindrique. L'évidement (220) cylindrique présente un diamètre supérieur à celui des surfaces extérieures de l'extenseur (10), et comporte une tige (270) passant axialement à travers l'évidement (220) cylindrique sur lequel l'extenseur (10) est placé. Des trous (208) obliques traversant des parois du dispositif (200) de polissage extérieur pour aboutir à l'évidement (220) cylindrique, permettent de diriger le milieu abrasif (M) de façon adjacente à des surfaces extérieures de l'extenseur (10), et provoquent un polissage des surfaces extérieures de l'extenseur (10). Le sens d'écoulement du milieu abrasif (M) peut être inversé de façon à produire un profilage symétrique de segments de l'extenseur (10). Après polissage de l'extenseur (10), on retire les extrémités de support (20) cylindriques et l'extenseur (10) est prêt à être implanté et à se dilater radialement à l'intérieur d'une lumière corporelle (L). Poli et profilé, l'extenseur (10) chirurgical expansible radialement permet de soutenir de manière plus efficace une lumière corporel (L) de manière à réduire des cas de thrombus, de resténoses ou d'autres complications médicales.

Title: Device and method for locating a mobile station in a mobile communication system
Inventor: KONG SEUNG-HYUN
IPC: H04B1/707
Filed: 1999-12-17
Granted: 2003-08-12
Abstract: A device and method for locating a mobile station (MS) in a mobile communication system. In the MS locating device, a first antenna and a second antenna of a base station (BS) are spaced from each other by a distance equivalent to a wavelength of an MS transmission channel multiplied by a predetermined coefficient, such as one half. A first frequency downconverter and a second frequency downconverter convert signals received from the first and second antennas to baseband signals and digitize the baseband signals to chip sample data. A first channel demodulator and a second channel demodulator recover the chip sample data received from the first and second frequency downconverters and output information about the symbol start and PN code of a specific MS signal. A controller outputs a PN code for identifying the specific MS and finger position information based on the symbol start and PN  code information received from the first and second demodulators. In addition, the controller may be supplied with orthogonal code information from the demodulator; in this case, the controller will output information concerning the specific Walsh code. A symbol data extractor extracts two symbols of the specific MS from the chip sample data received from the first and second frequency downconverters based on the PN code and finger position information.  An incident angle estimator estimates the incident angle of the received signal from the phase difference between the extracted two symbols. A location estimator estimates the location of the specific MS based on the estimated incident angle and the round trip delay (RTD) measured for the MS.

According to one embodiment, the system includes a transceiver system (318, 320, 322) for transmitting radio wave frequency signals to and receiving radio wave frequency signals from a base station (120); a set of modems (312), wherein each modem (310) in the set is coupled to the transceiver system; a set of subscriber units (304), wherein each subscriber unit is associated with authentication information; a switch (308) coupled to each of the modems and coupled to each of the subscriber units (304); a control system (314) in communication with the switch (308) and each of the modems; and a database (317) for storing the authentication information, wherein the database is accessible to the control system. The control system (314) determines an available modem from the set of modems when one of the subscriber units is activated. Further, the control system (314) directs the switch (308) to connect the activated subscriber unit (304) with the available modem (310), retrieves from the database (317) authentication information associated with the activated subscriber unit, and provides the available modem (310) with the retrieved authentication information. In this manner, the authentication information associated with the activated subscriber unit (304) is provided to the modem (310) that is handling the call. Consequently, the modem handling the call can transparently authenticate the subscriber unit in the same manner as in a conventional wireless communication service.
