Title: Selecting speech encoder and data rate according to transmission conditions in a radio communication system
Inventor: FAERBER MICHAEL
IPC: H04B17/00
Filed: 1997-12-19
Abstract: A method of speech transmission in a radio communications system wherein at least one characteristic value concerning the transmission conditions of the radio link is determined for a transmitted signal and compared with at least one threshold value. A speech encoder is selected according to the comparison such that a higher data rate speech encoder is used when there are good transmission conditions and vice versa. The characteristic value may be received signal amplitude, bit error rate (BER), a value proportional to signal transit time or signal to noise ratio. Two threshold values may be used such that the changeover from a higher to a lower data rate takes place with a poorer transmission quality than a changeover from a lower to a higher data rate. The higher data rate speech encoder has a ratio of protective bits to user data bits which is smaller than that of the lower data rate speech encoder. Selection of the speech encoder may take place at the beginning or during a connection and in combination with decisions about a channel change or handover.

Title: Locating the source of an unknown signal
Inventor: HAWORTH DAVID PATRICK
IPC: G01S5/06
Filed: 1995-09-20
Abstract: A method of determining the location of an unknown source (10) transmitting an unknown signal to satellite relays (14 and 16) comprises receiving the signal from the relays at respective receivers (18). The receivers (18) receive reference signals via respective relays from a common source (22). The unknown signal and reference signal received by each receiver (18) are processed coherently to preserve their timing and phase information relative to one another independently of signals received elsewhere. The signals are frequency downconverted and digitised, and transferred to a common processing computer (150). The computer (150) performs cross ambiguity function processing of the reference signals to determine their relative Differential Time Offset (DTO) and Differential Frequency Offset (DFO). It performs the like for the received unknown signals to determine relative DTO and DFO, relative time and frequency shifts being introduced between the unknown signals by incorporation of the reference signal DTO and DFO in order to enable the unknown signal DFO to be determined relative to the reference signal DFO. The reference signals are also employed to counteract phase noise and frequency drift effects in the unknown signals. From the unknown signal DTO and DFO the position of the unknown source (10) is calculated.

Title: Measuring rotary speed or direction
Inventor: BRAUN AUGUSTIN DIPL ING
IPC: G01D5/20
Filed: 1998-08-21
Abstract: A rotary member (2), whose rotary speed or direction is to be measured, is at least partially covered with conductive material such as a metal plate (3). Spaced around and in close proximity to the member (2) are electrical elements (4) which contain a reactive impedance, e.g. an RL or RC combination. These elements (4) are supplied with a series of voltage pulses (S) and the time taken for the voltage at the resistor (11) to rise to a threshold level is measured (9). This time is affected by the proximity to the RL combination of the conductive covering on the rotary member, in which eddy currents are induced, and this enables the rotary speed of the member to be determined. Provision of a plurality of RL elements around the member also enables rotary direction to be determined. In a further embodiment (Fig.2, not shown), the whole of the rotary element is covered in conductive material having regions which are selectively polarised so that the effect on the reactive impedance of the electrical elements is varied.

Title: Torsional damper having a slipping clutch to absorb peak torque
Inventor: ORLAMUNDER ANDREAS
IPC: F16F15/131
Filed: 1998-09-07
Abstract: A torsional vibration damper, for a motor vehicle main clutch, comprises a hub element 11 coupled to a first damping mass 13 by slipping clutch 12 having a release arrangement 34 which partially disengages or slips the clutch 12 when peak torques occur. Hub element 11 is clamped, via disc springs 32, 33, between clamping rings 28, 29 which have lever sections 30, 31 that cooperate with slanting surfaces 36 on release arrangement 34 when it moves under an influence of the peak torque. The slanting surfaces 36, via lever sections 30, 31, alters the clamping position of the rings 28, 29 from radius R1 to a possible minimum radius R2 so that torque transferred through element 11 is reduced, thereby slipping the clutch 12 and allowing relative rotation of the first damping mass 13 and second damping mass 22. In other embodiments the release arrangement may comprises ball and indentation/ramp means (see fig 9 to 13b and figs 20 to 21a) or swivelling sensor arrangement (see figs 14 to 15b) or catch means (see figs 16 to 19). Also the main clutch may be slipped to absorb the peak torques (see figs 16 to 20).

Title: An apparatus and method for detecting and decompressing instructions from a variable-length compressed instruction set
Inventor: WORRELL FRANK
IPC: G06F9/32
Filed: 1997-06-10
Abstract: A microprocessor is configured to fetch a compressed instruction set which comprises a subset of a corresponding non-compressed instruction set. The compressed instruction set is a variable length instruction set including 16-bit and 32-bit instructions. The 32-bit instructions are coded using an extend opcode, which indicates that the instruction being fetched is an extended (e.g. 32-bit) instruction. The compressed instruction set further includes multiple sets of register mappings from the compressed register fields to the decompressed register fields. Certain select instructions are assigned two opcode encodings, one for each of two mappings of the corresponding register fields. The compressed register field is directly copied into a portion of the decompressed register field while the remaining portion of the decompressed register field is created using a small number of logic gates. The subroutine call instruction within the compressed instruction set includes a compression mode which indicates whether or not the target routine is coded in compressed instructions. The compression mode is stored in the program counter register. The decompression of the immediate field used for load/store instructions having the global pointer register as a base register is optimized for mixed compressed/non-compressed instruction execution. The immediate field is decompressed into a decompressed immediate field for which the most significant bit is set.

Title: Converting between serial and parallel data
Inventor: DRUMM OWEN
IPC: H03M9/00
Filed: 1999-01-13
Abstract: A system for the serial-to-parallel conversion of binary data comprises a random access memory (RAM) 10 into which parallel data bits are written, and from which parallel data bits are read, with a word width of N bits, at least N-1 bit stores S0-S7 connected by an N-bit wide read/write data bus 14 to the RAM. In order to convert each N consecutive bits of a serial input data stream 16, an N-bit data word is repeatedly read from the RAM to the bit stores and written from the bit stores back to the RAM in synchronism with the serial input bits. Each time the word is read out and before it is written back, the then current serial input bit is substituted for a different one of the bits of word. Thus, after N such read/write operations the N-bit word written back to the RAM 10 corresponds to the N consecutive bits of the input data stream 16. The system may be modified to provide parallel-to-serial conversion (not shown) and multiplexed conversion of plural signal channels (Fig 4), e.g. for S-DIF audio signals,
