Title: Plural-channel sound processing
Inventor: SIBBALD ALASTAIR
IPC: H04S5/00
Filed: 1993-03-18
Abstract: An artificial head (2) and a plurality of discrete monophonic microphones (8, 10, 12) are used to record one or more sound sources. The signals (14, 16, 18) from each of the microphones (8, 10, 12) then undergo binaural synthesis based upon acoustical properties of a real human head or the artificial head (2), and the signals (4, 6) from the head are equalised using air-to-ear transfer functions of the artificial head (2) or a real head. The resultant signals are combined by summing the individual left (48) and right (50) channels together and then these summed signals (52, 54) are transaural crosstalk compensated (56) to provide final left and right channel signals (58, 60) suitable for recording or playback which provide a three-dimensional sound effect to a listener both via headphones and loudspeakers. <IMAGE>

Title: Programmable code store circuitry for a non-volatile semiconductor memory device
Inventor: DURANTE RICHARD JOSEPH
IPC: G11C16/10
Filed: 1994-10-06
Abstract: A flash memory device includes programmable code store circuitry. The code store circuitry stores algorithms used by an array controller to erase and program a nonvolatile main memory array, and includes a nonvolatile memory 100 for the algorithm instructions. The circuitry also includes support circuits, such as address multiplexer and decode circuitry 102 - 108, sense path circuitry 112, main array interface circuitry 110 and voltage generators 114 - 120. These circuits operate in several modes. In read mode, they ensure that the instructions in memory 100 are output to the array controller. In program and erase modes, the support circuits allow control of voltage level applied to the instruction memory, output of instruction data to the user, and input of modified instructions to memory 100 via a page buffer 42 (Fig. 1). The support circuits are placed in the various modes via control signals output from control registers. Because these control registers are accessible to the device user, the user controls the mode in which the code store circuitry operates. <IMAGE>

Title: Method of generating a straight-on travel signal
Inventor: POGGENBURG RUDIGER
IPC: B60T8/172
Filed: 1994-11-14
Abstract: A method is described by means of which an output signal is generated when a vehicle is travelling straight on. Wheel speed signals 1 - 4 are fed to a block 5 which computes the difference between the signal sums for the two sides of the vehicle. The resultant difference is filtered at 6 to remove short-term variations, and the filtered and unfiltered signals are subtracted at 8, thus removing effects of tyre size tolerance. The subtractor output is compared at 9 with a threshold value (on line 11) which varies with the vehicles momentary speed. If the threshold is not exceeded, the vehicle is considered to be travelling straight on. A number of refinements are described. <IMAGE>
Patent GB-2285685-A (GB)
Title: Attenuating tube waves in seismic well prospecting
Inventor: NAVILLE CHARLES
IPC: G01V1/52
Filed: 1994-12-16
Abstract: The method enables the attenuation of waves known as tube waves propagated along the well and causing interference signals to be picked up by seismic receivers coupled with an underground formation crossed by the well, in response to elastic waves applied to the formation. The method consists of carrying out prospecting operations whilst dispersing in the liquid in an upper part of the well a gas that is essentially insoluble in this liquid and sufficiently compressible to absorb at least a proportion of the energy carried by the tube waves to the seismic receivers. The gas can be introduced into the liquid by a chemical reaction of selected constituents introduced from tanks 7 into a reaction chamber C in the well. Alternatively, the reaction is triggered at the surface and pressurised gas produced is injected into the well. Explosive chemical reactions in the well may alternatively be used. <IMAGE>

Title: Bridging clutch for hydrodynamic torque converter has valve opened in depend ence on speed, temperature or viscosity
Inventor: MIDDELMANN VOLKER
IPC: F16H45/02
Filed: 1995-02-07
Abstract: The bridging clutch which is mounted actively between an output member of the torque converter and the input member has an axially displaceable piston 136 which is provided on one side with an engagement chamber 124 for the bridging clutch and on the other side with a disengagement chamber 125. The bridging clutch has at least one valve 138 dependent on its speed and/or temperature and/or viscosity of the fluid, and this valve influences the pressure difference existing between the two chambers and also the engagement force of the bridging clutch. The valve can additionally or alternatively control a fluid stream between the two chambers, and in this case the valve is opened in a lower speed and/or temperature range and/or upper viscosity area and is closed in a second higher speed and/or temperature range and/or lower viscosity range. If speed responsive the valve preferably operates by centrifugal action. <IMAGE>
