Title: A multiple user spread-spectrum communication system
Inventor: SCHAEFFER DENNIS RAY
IPC: H04B7/005
Filed: 1992-06-08
Abstract: A communication system having a site (42) employing a plurality of communication channels. Each channel is assigned a desired received signal strength threshold. A channel is assigned to a subscriber unit (43a, 43b) based upon the strength of the signal received at the site (42) and the power control range of the subscriber unit (43a, 43b). The selection of a channel may be performed either by the site (42) or the subscriber unit (43a, 43b). In an FDMA environment (50), each separate frequency division channel may be assigned different received signal strength thresholds. In a non- overlapping time interval (TDMA) environment (70), each separate time division channel may be assigned different received signal strength thresholds. In another embodiment (80), a combination of FDMA and TDMA environments can be used. <IMAGE>

Title: Anchoring arrangements for windscreen wiper arm springs
Inventor: LEWIS MARK ANTHONY
IPC: B60S1/34
Filed: 1996-05-24
Abstract: An anchor tail 4 is provided, which will be attached to the end of the biassing spring of a pivotal wiper arm assembly. This tail terminates in an elongated head 5 to create a T-formation. The head 5 is passed through a slot 6 in a plate 7 forming part a drive head 1 and is rotated through 90{ so that the head 5 is securely located beneath the body of the plate 7. A slot 8 is formed in the other end of the tail 4 for location of a hook at the end of the biassing spring. Any wear created by rocking of the tail 4 and head 5, under pressure of the biassing spring, will be distributed over the length of the head 5. The potential for wear due to abrasion between the tail 4 and the plate 7 can be reduced by forming the end of the slot 6 with a rounded or angled upper face.

Patent GB-2312319-A (GB)
Title: Video storage
Inventor: BOPARDIKAR RAJU C
IPC: H04N5/262
Filed: 1997-04-11
Abstract: Video data in the form of a plurality of digitised frames, is stored on a plurality of magnetic disks. Each image frame is striped across a plurality of disks and redundant parity information, derived from the stripes, is written to an additional disk. Disk failure is detected and in response to this detection missing data is regenerated from the parity information. This allows the transfer of video data in real time to be maintained for output so that the system remains operational. While data is being read in real time, derived from regenerated data, the regenerated data is written to an operational disk, thereby reprotecting the data in the event of a subsequent failure. Frame supplied to output are labelled as being protected or unprotected and application programs may respond to this status information as considered appropriate. Image data is transferred at a rate at least dual to the video display rate.
