  • Publication number: 20110070759
    Abstract: A card connector has a housing with a base and a side rail extending from the base to define a card-insertion cavity. A plurality of conductive terminals are supported by the housing and extend at least partially into the card-insertion cavity for contacting a card inserted into the card-insertion cavity. A push-push style card locking and ejection mechanism retains the card in the card-insertion cavity upon a first push and which ejects an inserted card upon a second push. The mechanism includes a slide member positioned for slidable movement on the side rail and a biasing member contacting the slide member for selectively exerting an ejection force on the slide member. The slide member includes a slide surface that slides along a guide surface of the side rail. A damping material is interposed between the slide member slide surface and the guide rail guide surface for retarding movement of the slide member on the side rail in response to an ejection force from the biasing member.

  • Publication number: 20080232327
    Abstract: here is provided a new multi-user receiver configuration technique which solves the problems of the user signal separation function of the multi-user receiver such as the interference canceller, decorrelator, and least square error detection. That is, there is provided a code-division multiplex signal decorrelation/identification method for realizing much more excellent performance than the aforementioned methods in the aspect of the power band amplitude product required for one-bit transfer as the evaluation reference of the CDMA method. A function for successively judging the best user is added to the conventional least square error detector MMSE-D shown by a dotted line in the block diagram of the successive detection type least square error detection method (SD-MMSE).

  • Patent number: 7335064
    Abstract: A memory card connector includes an interior cavity for receiving a memory card. An insulating housing has a rear terminal-mounting section and at least one longitudinal side wall section extending forwardly from one end of the rear section. A metal shell covers at least a portion of the insulating housing and includes a cover plate overlying at least a portion of the longitudinal side wall section of the housing An engaging structure includes an engaging projection on one of the cover plate of the metal shell or the top surface of the side wall section of the housing extending into an engaging opening in the other of the cover plate or top surface to prevent relative movement therebetween in a plane generally parallel to the cover plate and top surface.
