Title: Parallel processing of high bit rate video signals
Inventor: BAZZAZ PAUL
IPC: H04N7/26
Filed: 1993-12-22
Abstract: In order to reduce the required bit rate for processing of a video signal 10, successive periods T (particularly fields) of the incoming signal are switched into n respective processing channels. Each channel comprises a (field) memory which reads out the video signal at a bit rate of 1/n of the incoming bit rate ie decompresses it over n periods, nT. Each memory further reads out each decompressed signal after a delay of T, thus providing, synchronously, signals IN1D, IN2 from adjacent fields. Each channel additionally comprises recursive processing means 11, 21, 31; 12, 22, 32 etc including at least one feedback loop, for parallel processing of n signals. The method is particularly described for motion vector processing of an HDTV signal where the incoming fields are time division multiplexed into four parallel channels at 1/4 the incoming bit rate, so that currently available, standard bit-rate processors may be used on high bit-rate signals. <IMAGE>

Title: Surface ionization detector for detecting trace amounts of organic molecules
Inventor: NACSON SABATINO
IPC: G01N30/64
Filed: 1994-09-02
Abstract: A surface ionization detector for detecting organic molecules such as illicit drugs and non-organo-nitrate explosives includes a heated surface 22 such as a platinum wire and a collector electrode 48. A sample containing trace amounts of the organic molecules in ambient air is directed over the heated surface maintained at a temperature in the range of 500 DEG C to 800 DEG C, thereby causing the molecules to decompose into fragments. A polarization voltage between 18V and 24V is applied to ionize the fragments which are then collected by the collector electrode. An electrometer 24 connected to the collector electrode measures the current and a change in the current indicates the presence of ionized fragments, and thereby indicates the presence of the organic molecules. The temperature of the heated surface and the polarization voltage are optimized for detection of particular organic molecules. <IMAGE>

Patent GB-2326190-A (GB)
Title: A ball joint
Inventor: FREE BERNARD JOHN
IPC: F16C11/06
Filed: 1997-06-14
Abstract: A ball joint comprises a ball 10 mounted in a socket 16. The ball 10 has a spherical surface 22 and a projection 32. The socket 16 provides a first throat 30 through which the spherical surface 22 cannot pass and a second throat 44 through which the projection 32 cannot pass. In normal use the spherical surface 22 is retained by the first throat. If however the first throat 30 becomes sufficiently worn so that it no longer retains the spherical surface 22 then disengagement of the ball 10 and the socket 16 is prevented by the projection 32, which is retained by the second throat 44. In this way catastrophic failure of the ball joint is avoided.
