Title: Determination of transport format combination indicators at the end of data blocks and application to later blocks if the earlier block is error free
Inventor: ISHIDA KAZUHIRO
IPC: H04L1/00
Filed: 2003-08-28
Abstract: In a wireless system, in particular a third generation partnership project (3GPP) system, plural channels with different data arrival times are multiplexed together. At the end of each data block (eg (0,0) (1,0) (2,0)) a transport format combination indicator (TFCI) which specifies the transport format of all the channels is detected. When on block is received (eg (1,0)) the TFCI is detected and an error check is performed on the block. If the block is error free the TFCI is taken to be correct and the possible transport formats (TF) of the channels (0 and 2) whose blocks do not end at the same time are restricted to be those indicated in the TFCI. This allows the later blocks to be decoded without having to determine their transport formats from their own TFCI's.
Patent GB-2393054-A (GB)
Title: Electrical notch filter with acoustic resonators
Inventor: FRANK MICHAEL LOUIS
IPC: H03H9/58
Filed: 2003-09-10
Abstract: The filter 10 uses acoustic resonators 14 in place of capacitors. A resonator, e.g. FBAR or SAW, behaves similar to a capacitor outside of its resonant frequency and so does not impact the function of the network, outside of its resonant frequency. At this resonant frequency, the resonator quickly transitions from capacitor to short circuit to open circuit and back to capacitor. Thus, the will deliver open and short circuits independent of the standard LC filter resulting in a structure with an additional notch, a notch with the characteristics delivered by a very high quality resonator. This notch can be much sharper and closer to the pass band than is possible with ordinary inductors and capacitors.

Title: High expansion sealing device with leak path closures
Inventor: MICKEY CLINT E
IPC: E21B33/12
Filed: 2003-07-31
Abstract: A high expansion packer or bridge plug is described. It features an external portion of a soft material (28) that flows into spiral exterior leak paths (30) formed when the sealing element (20) is subjected to longitudinal compression.

Title: Air mattress with groups of airbags which exhaust through a heat sink structure.
Inventor: HAN CHUN-CHU CHEN
IPC: A47C27/08
Filed: 2005-07-14
Abstract: The air mattress 2 comprises groups of air bags 21 and 22. The groups of airbags are connected to a control unit 1 which has an air pump 11. This pump supplies compressed air to a group of airbags 21 or 22 through conduits 24 and 25 respectively, as selected by control valve 12. When one group 21 is connected to the pump, air from the other group 22 drains or discharges through exhaust conduit 26 to heat sink layer 23 which is laid over the airbags 21,22. The air passes through exhaust holes 23a in the heat sink layer, taking away some heat and moisture to make the mattress dry and comfortable. The pump supply alternates between the airbag groups according to the position of valve 12 (figure 3). In an alternative (figure 4), the air bags are held within a heat sink layer 23 which is a hollow structure. There may be more than two groups of airbags.
