Title: Door entry prevention device with biased lock concealing device
Inventor: JOYCE MICHAEL
IPC: E05B17/20
Filed: 2007-05-14
Abstract: A door entry prevention device for use in a door having a cylinder lock has a concealing device 25 moveable between first and second positions. The lock concealing device 25 is biased towards said second position, wherein, in use, the lock concealing device is retained in its first position by a part of the cylinder lock and is released and urged to its second position when said part of said cylinder lock is detached from the remainder of the lock. The device prevents unauthorised entry when part of the cylinder lock is detached by force. The lock concealing device may comprise a spring loaded sliding plate 25 mounted in housing 23. The housing 23 may be mounted on elongate plate 21. A tab or flap 53 may prevent the plate from returning into the housing. There is also described a door provided with a door entry prevention device.

Title: Closed loop MIMO communication system using SISO r.m.s. delay spread to estimate eigen coherence bandwidth.
Inventor: HART MICHAEL JOHN BEEMS
IPC: H04J99/00
Filed: 2007-06-08
Abstract: Closed loop MIMO FDD schemes can offer significant performance gains for OFDM based wireless communication systems over open loop MIMO schemes. However, the pre-coding weights (eigenvectors) on each of the frequency bands need to be updated and this adds extra overhead. The number of adjacent frequency fingers which can use the same pre-coding weights is governed by the coherence bandwidth of the eigen spatial modes. The receiver uses the average r.m.s. delay spread of the SISO channels as an indicator to the eigen coherence bandwidth, rather than explicitly calculating the eigen coherence bandwidth itself. This technique can be applied to TDD schemes as well, where the channel estimation is done with the reverse link, eliminating the need for feedback. The TDD transmitter can estimate the eigen coherence bandwidth on the basis of average r.m.s. delay spread, which saves computational effort.

Title: Anti-aliasing computer generated graphics by alpha testing each sampling point of fragment individually
Inventor: NYSTAD JOERN
IPC: G06T15/50
Filed: 2009-01-30
Abstract: When an alpha test is performed as part of the rendering process in a multisampled graphics processing pipeline, rather than taking the single alpha value initially defined for each fragment 80, 81, 82, 83, an individual alpha value is generated in respect of each of covered sampling position that the fragment in question is being used to render. The individual alpha values estimated for each sample position are then individually compared with a threshold alpha value defined for the alpha test, and the result of this alpha test comparison is used to decide either keep or discard the sample position from further processing. Claims are also included specifying that an individual parameter value rather than merely an alpha value may be generated for a sampling point, and subsequently used in processing in relation to that point.
