Patent CA-2258323-A1 (CA)
Title: Method for transmitting superimposed image data in a radio frequency communication system
Inventor: HASSAN AMER
IPC: H04N21/2662
Filed: 1997-07-09
Abstract: The present invention relates to a method for transmitting image data for superimposed images via wireless devices in a radio frequency communication system. The original image is transmitted via a communication channel to a receiving unit. The original image is then revised to form a revised image.  The revised image is compared to the original image to determine the differences between the revised image and the original image. These differences comprise a difference image which is then transmitted to the receiving party. At the receiving end, the difference image is recombined with the previously-transmitted original image to reform the revised image. In a preferred embodiment, the original images and difference images are preferably decomposed and progressively transmitted to the receiving unit in response to image data requests from the receiving unit.

Title: Connector having surface mount terminals for connecting to a printed circuit board
Inventor: MICHAUX GWEN L
IPC: H01R12/57
Filed: 1999-06-30
Abstract: A connector having a set of terminals that are preferably coplanar and are used to connect electrical components, such as surface mount components, with a printed circuit board (PCB). The connector uses an insulative wafer to achieve and to maintain the coplanarity of the terminals. Initially, the terminals are overbent so that as the wafer is being placed in the connector housing, the terminals contact the wafer on a slope of the wafer. In other words, as the wafer is being mated with the connector housing, the wafer pushes against the terminals to establish coplanarity. Thus, the wafer works in conjunction with the terminals in the connector housing to establish coplanarity. Therefore, the connector supports the terminals for positioning while ensuring that the terminals are coplanar.

IPC: H04B7/005
Filed: 1998-01-09
Abstract: The present invention relates to a method and an arrangement for assignment of mobile stations (MS1-MS4) to so called multi-user channels (CH1, CH2) in a radio communication system. With information on mobile stations' (MS1, MS2 and MS3, MS4 respectively) power demands (P) from a base station (BS) with which they communicate, effective time spans for transmission of information (T) and/or relevant angular power spectrum (a1, a2) from the base station (BS) channels (CH1 and CH2 respectively) are allocated in such a manner that the total energy transmitted from each base station (BS) is minimized for transmitting information to its associated mobile stations (MS1-MS4). As a consequence the total level of interference in the radio communication system to which the base stations (BS) belong will be minimal, which results in a high efficiency for the system.
