Abstract: The present invention provides an electrical connector for connecting a contact pad of an IC card to a printed circuit board. In particular, a smart card connector is provided which elevates the connector above the PCB for placement of additional components therebeneath. The connector includes a housing having a top component and a bottom component affixed thereto wherein the top and bottom components together define a card insertion ingress at a front portion of the connector. The ingress is sized and shaped to accommodate linear sliding insertion of a smart card therein along a card insertion plane defined between the top and bottom portions. The top portion of the connector supports a plurality of electrical contacts therein wherein each contact includes an inner extent having a spring-like undulation at a freely deflectable extent positioned in the card insertion plane. Upon card insertion, a contact pad on the card engages the freely deflectable extent such that the undulation moves upward into a corresponding indentation defined along a bottom surface of the top portion of he connector. Upon retraction of the card, the undulation resiliently returns to its original position in the card insertion plane. Each contact further includes an outer extent that protrudes normally from the top portion of the connector for termination to the PCB. The contacts are desirably distributed in even and aligned rows that enable placement of all contacts in the top portion of the connector.

Inventor: HARLES GUY
IPC: H04B17/40
Filed: 1998-12-17
Granted: 2004-02-24
Abstract: Pour déterminer les caractéristiques de constituants d'une voie de communication, par exemple d'un transpondeur dans un satellite de communication, un signal multiplex f(t) indépendant est modulé avec un signal de pseudo-bruit PB(t) et transmis par la voie de communication à un niveau inférieur au niveau d'un signal de charge utile qui est transmis simultanément par la voie de communication. Le signal reçu s'(t) est mis en corrélation avec le même signal de pseudo-bruit PB(t) pour produire un signal multiplex récupéré f'(t). Le signal multiplex indépendant f(t) et le signal multiplex récupéré f'(t) peuvent tous deux être utilisés pour déterminer les caractéristiques désirées. Etant donné que le signal multiplex indépendant s(t) modulé PB est transmis à un faible niveau, il est possible d'effectuer des mesures sans interrompre le signal de charge utile.

Title: System and method for defining location services
Inventor: HAYES STEPHEN
IPC: H04W4/02
Filed: 1999-04-19
Granted: 2009-10-06
Abstract: A telecommunications system and method is disclosed for defining location services in a simplified manner based upon whether the positioning request is an interactive request or a batch mode request. In order to initiate a positioning request, a Location Application (LA) must first register with at least one Mobile Location Center (MLC), define the service parameters specific for that LA and receive a Location Application Identifier Number (LAIN). Thereafter, the LA can send either an interactive or batch mode positioning request along with the LAIN. An interactive positioning request is a request to position a specific subscriber or group of subscribers immediately, while a batch mode positioning request is a request to position a subscriber or group of subscribers when a particular event defined by the LA occurs. The definition of location services is decoupled from issues, such as the point of origin of the request, the identity of the subscriber to be positioned and authorization options.
