Title: Cdma system transmission matrix coefficient calculation
Inventor: FAZILI MUHAMMAD USMAN
IPC: H04B1/7093
Filed: 2002-12-19
Granted: 2008-05-20
Abstract: An apparatus and method for data processing particularly useful in combining convolutions of the spreading code, scrambling code and channel response in order to construct a system transmission coefficient matrix, while maintaining the same circuit size and execution time relative to performing each convolution separately. One register (200) for processing real channel response values and a second register (100) for processing imaginary channel response values, are used for moving channel responses through the convolution. In place of multipliers, an optimized minimum number of adders ( A12-A13; A25-A28) connected in a pyramid configuration are used to perform the necessary multiplication of the codes, for simplicity of construction. By including the channel code transformation from binary representation to complex representation as part of the overall method, unnecessary adders are eliminated from the apparatus.

Title: Method of manufacturing boot for constant-velocity universal joint and manufacturing apparatus for use in the method, and boot for constant-velocity universal joint
Inventor: SUEOKA KAZUHIKO
IPC: B29C49/04
Filed: 2004-08-11
Granted: 2011-07-26
Abstract: There is disclosed a boot for a constant-velocity universal joint, in which a secondary molded portion including a thick portion is formed on an inner peripheral portion of a large-diameter side end portion formed as a primary molded member and in which a material in secondary molding is prevented from leaking. A manufacturing method includes: a step of forming a secondary molding space between a large-diameter side end portion inner peripheral surface of the primary molded member and an outer peripheral surface of a core mold; and a step of injecting a molten material into the secondary molding space to mold the secondary molded portion. The step of molding the secondary molded portion includes the steps of: applying a pressure of the molten material injected into the secondary molding space to a tapered surface 27 extending toward the large-diameter side end portion from a small-diameter portion 7b just in the vicinity of a large-diameter side end portion 3, expanding the tapered surface toward the small-diameter portion, and pressure-contacting the small-diameter portion 7b held between the inner peripheral surface of a divided mold 51 and the outer peripheral surface of a core mold 69 onto the core mold outer peripheral surface.

Abstract: Réseaux, dispositifs et procédés concernant la réseautique sans fil. L'invention concerne un réseau sans fil mettant en application des noeuds remplissant à la fois des fonctions de distribution et de raccordement. Ces noeuds constituent les éléments clés d'un réseau sans fil qui serait développé et contrôlé par un opérateur de réseau sans fil. Chaque noeud contient un module de distribution sans fil couplé au dispositif sans fil de l'utilisateur final au moyen d'une conception point-à-multipoint. Chaque noeud intègre également au moins un module sans fil de raccordement comportant une antenne directionnelle sans fil. Chaque module de raccordement communique au moyen d'une liaison radio point-à-point avec le module de raccordement d'un autre noeud. Les noeuds du réseau sans fil sont interconnectés, de manière à créer un réseau de raccordement maillé. Etant donné la nature de ce dernier, il est possible de détourner le trafic de données autour d'obstacles susceptibles d'empêcher des liaisons à portée optique. De plus, ce réseau maillé permet d'effectuer l'acheminement dynamique de trafic de données afin d'éviter des points d'encombrement ou des liaisons invalides dans le réseau.

Granted: 2011-07-19
Abstract: The present invention provides a method to optimize the configuration of a symbology reader without the need for user intervention. Following a predetermined number of successful decodes, the reader automatically determines the symbology of interest and disables the decoding algorithms not being used. For example, if after four or five successful decodes have occurred and the unit determines that all of the successful decodes were of a single symbology type such as a PDF417 barcode, all other decoding algorithms, with the exception of the PDF417 decoder, will be disabled. Other embodiments may be included which adjust the scan window size and the image capture parameters of the reader based on the symbology of interest.

Granted: 2014-07-29
Abstract: A method and system for locating a mobile user of one or more mobile users while on a call in a wireless telecommunication network utilizes a decision network that determines if the call signal is propagating through a repeater station. When the call is propagating through a repeater station, the decision network alters the signal measurement parameters to correspond with the location of the mobile user relative to the repeater station co-ordinates. By revising signal measurement parameters to compensate for repeater stations, the present invention provides for improved position estimates of the location of the mobile user in the network. For multiple cell soft handoff conditions, the decision network utilizes trained neural networks.

Abstract: A method and conjugate for selectively killing antigen-activated T cells are disclosed. The conjugate is composed of a substantially uncharged antisense compound targeted against the human cFLIP protein, and a reverse TAT (rTAT) polypeptide coupled covalently to the antisense compound. The rTAT polypeptide is effective to produce selective uptake of the conjugate into antigen-activated T cells, relative to the uptake of the conjugate into non-activated T cells. The cFLIP antisense compound causes activation induced cell death (AICD) of activated lymphocytes. The method is useful in treating transplantation rejection and autoimmune conditions.
