Title: Controlling signal-to-noise ratio in noisy recordings
Inventor: BISPING RUDOLF
IPC: H03G5/16
Filed: 1993-11-09
Abstract: A method for remodelling audio signals in frequency range by which an improvement of the signal-to-noise ratio is possible, in particular for historical recordings. The process builds on spectral analysis that makes it possible to manipulate frequencies, bandwidths, and amplitudes of isolated spectral components in any way. For remodelling, those components are selected that 1) are relevant for acoustic perception and 2) can be classified as tonal because of their temporal stability. By enhancing the tonal portions relative to the noisy components (tonal contrast enhancement) substantial improvements of the acoustic quality are obtained while preserving the natural acoustic impression. With the help of parallel computer architecture based on transputer and signal processors, remodelling is performed within a period that appears acceptable for studio work.   <IMAGE>

Patent GB-2281156-A (GB)
Title: Battery charging device with fault detection
Inventor: KOHL WALTER
IPC: H02J7/16
Filed: 1994-07-18
Abstract: In the event of faults, a fail safe circuit FS is operative to energise a battery charge warning lamp LK and to switch connection of the generator field winding from a main regulator Re1 to a standby regulator Re2. A conductively defective main regulator state is detected when circuits 3 and 4 simultaneously give a high output to AND gate 5. Circuit 3 senses continuous field winding excitation by detecting a low average voltage on a terminal DF1, and the circuit 4 responds to the voltage at a terminal D+ being above a maximum value. Lamp LK is also energised and regulator Re2 brought into use if a circuit 6 senses interruption in field winding excitation. If the D+ terminal voltage drops below a first reference level, circuit 6 causes a load to be connected to that terminal for a preset period. If the D+ terminal voltage then drops below a second reference, lower than the first, then circuit 6 outputs a high signal to OR gate 2 to effect the change over to the standby regulator Re2. Gate 2 latches in the standby regulation state in response to a high output from gate 5 or from circuit 6. The fail safe circuit FS can be used with a generator having zener diodes Z in at least one of its rectifier bridges G1. When the ignition switch ZS is first switched on, a circuit 1 acts to switch the regulator changeover relay 8 back and forth once to effect cleaning of the relay contacts. <IMAGE>

Title: Two stage inflator with module venting for passenger side airbags
Inventor: PATEL JITENDREA
IPC: B60R21/26
Filed: 1995-04-27
Abstract: A passive two stage passenger-side inflator (10) is disposed in a module funnel (14) coupled to an airbag (100). The two stage inflator provides a gentle onset during the initial deployment to help protect out-of-position passengers. The second rapid stage (30) is ignited passively by hot gas communication from the first stage (28). The inflating gases from both stages flow through the module funnel (14) into the airbag (100). Openings (76,78) in the module funnel (14) permit pressure relief venting of the airbag (100) further to protect out-of-position passengers even if the bag has not yet unfolded. Preferably, the module is mounted so that the funnel vent openings direct the vented gas into the instrument panel, thus minimizing the particulate matter released into the passenger compartment. <IMAGE>

Patent GB-2314346-A (GB)
Title: Rapid thermal annealing
Inventor: OJHA SURESHCHANDRA MISHRILAL
IPC: G02B6/12
Filed: 1996-06-22
Abstract: Annealing a planar waveguide layer is critical because small structural imperfections lead to optical problems. Chemical vapour deposition of the layer tends to leave gaseous substances bonded to the deposit, which on being driven off by initial annealing warm-ups leave cavities requiring densification. Traditional annealing methods take several hours. This invention proposes a rapid heating of the layer to a temperature below the flow temperature, maintaining this temperature for about 30 seconds, then rapid heating up further to a temperature close to or above the flow temperature, maintaining this temperature for up to 65 seconds, then allowing the substrate and layer to cool rapidly to room temperature. In one embodiment a buffer layer is deposited first in top of which a core layer is deposited and then the annealing is carried out. In another embodiment the buffer layer is grown by thermal oxidation instead of by CVD and a core layer is thereafter deposited by CVD.

Title: Brake system for a road vehicle
Inventor: KUPFER WALTER
IPC: B60T8/1766
Filed: 1996-06-25
Abstract: In a brake system for a road vehicle, each wheel brake is assigned a brake-pressure regulating elements 16-19 which includes a piston pump 36, the output of which decreases as brake pressure increases. Brake pedal operation results in transmission of a desired retardation signal from transmitter 21 to an electronic control unit 20, which produces the required actuating signals for the elements 16-19 from a comparison of the desired and actual retardation signals. The output of each pump 36 per pump cycle is small relative to the volume required to achieve maximum pressure at the respective wheel brake. With the vehicle stationary and the transmitter 21 actuated, (a) valves 42 shut off the brakes from reservoirs 38, 38' and, given a reduction in the transmitted signal, allows brake fluid to flow out of the brakes into the reservoirs, and (b) the pumps and brakes may be activated intermittently to facilitate cooling. Valves 42 for rear-wheel brakes 13 and 14 may be replaced by valves (42', figure 4) with a disc (98) and rotor (93) rotated by motors 34.

Title: Communication device using switching current mirror in PLL frequency synthesiser
Inventor: ABDI BEHROOZ
IPC: H03L7/183
Filed: 1997-02-06
Abstract: A communication device e.g. a transceiver or a paging receiver comprises, in addition to the usual circuitry for transmitting or receiving signals, a pll frequency synthesiser. The synthesiser includes a charge pump including a first switched current mirror 204 associated with a first current switch 202, a second current mirror 208 associated with a second current switch 206 and a third current mirror 210. The first current mirror selectively supplies a reference current from 216 to first or second paths 218 or 220 in dependence upon an input 160 received from the loop phase comparator. When current flows through path 220 a biassing voltage is developed at gate of 228 and also at gate of 224 since no current flows through resistor 226. Transistors 224, 228 form a current mirror and a current flows through the cascode transistor 230 to output 158. When current is switched to path 218, transistor 228 is turned off. Circuits 206, 208 operate in a similar manner to input received at 162.
