Title: Power system with load matrix
Inventor: KINNARD J ROTHE
IPC: H02J1/10
Filed: 2003-03-07
Abstract: A method and system for delivering electrical energy from multiple power supplies 210 to multiple loads 250. Each power supply 210 can have multiple independent outputs 220. Each load 250 is coupled in a matrix pattern to at least one output 220 from each of the different power supplies 210. This wiring system provides redundancy in that if one output 220 or one power supply 210 fails, an output from another power supply can still provide power to the loads 250. The number of over-current protection devices 230 needed with the matrix wiring system is reduced compared to traditional wiring methods. Also, the level of safety is greater under the matrix approach rather than the traditional approach. The matrix wiring system also aids in pinpointing faulty components. Finally, the matrix wiring approach allows a gradual degradation of the power distribution system when failures of the loads 250 or the power supply outputs 220 occur.

Title: DC to DC converter with voltage clamp circuit
Inventor: MELGAREJO MANOLO MARIANO M
IPC: H02M3/337
Filed: 2003-06-06
Abstract: A zero voltage switching (ZVS) or zero voltage transition (ZVT) bridge converter for driving a rectifier circuit has a clamp winding or inductor NCL is placed in parallel with a resonant choke NP of the bridge converter. The clamp winding clamps the voltage at the resonant choke. Clamping the resonant choke in turn limits the voltage at the secondary winding n2 of an output transformer T1. The output transformer is connected to the rectifier circuit. By limiting the voltage at the output transformer, the voltage at the rectifier circuit is limited as well. This limits excessive voltage overshoot and severe ringing.

Title: Method and apparatus for measuring electromagnetic emissions
Inventor: DOMOKOS JOHN
IPC: G01R31/00
Filed: 2003-06-30
Abstract: Electromagnetic emissions from a device under test are received by an antenna 1 of a receiver. The receiver is operable in two modes: in a first mode the received signal is sampled by means of a sampler 3 connected to an impulse generator 7 when switch 5 is in position a. The sampled signal is supplied to an IF amplifier 8 and analogue to digital converter 10. The received signal is sub-sampled in this circuit path to give a compressed signal in the frequency domain. The sub-sampled signal is analysed, for example using a Fast Fourier Transform, to determine what spectral components are present. These components are stored in a look up table memory 14. In a second mode, switch 5 is set to position b and the received signal is multiplied by a signal from local oscillator 6. The frequency of local oscillator 6 is set according to the frequencies stored in memory 14. In this mode the receiver operates as a superheterodyne or digital down converter. The receiver is able to quickly determine the frequencies present in an electromagnetic emission, especially when the emission contains both periodic and irregular components. In an alternative embodiment, switch 5 may be replaced with a splitter and both modes performed simultaneously.

Title: Averaging of error probabilities by inversion of retransmitted bits corresponding to positions in a signal constellation in a CDMA system
Inventor: KIM NOH-SUN
IPC: H04L1/00
Filed: 2002-10-15
Abstract: In a mobile communications system, upon request for a retransmission from a receiver, a transmitter inverts initially transmitted coded bits if the retransmission is odd-numbered, modulates the inverted bits and transmits the modulated bits to the receiver. The receiver recovers the coded bits by remodulation. By reversing the positions of modulation symbols in different regions of a signal constellation, the error probabilities of initial transmission bits and retransmission bits are effectively averaged and decoding performance is improved. The embodiment is a CDMA system.

Patent GB-2406745-A (GB)
Title: Signal-processing
Inventor: RODIN FREDRIK GUSTAF
IPC: G10L21/0208
Filed: 2004-09-15
Abstract: Processing of a received telephone-signal to limit sound-pressure from an earpiece 3 involves frequency-dependent limitation (7) after DTMF-tone suppression (5,6). The energies SyN of synthesised frequency-components 1-N of the sampled signal are computed within the limiter 7 from weighting coefficients cN1,cN2 derived iteratively by an adaptive LMS filter 10 for the sine and cosine pairs of the synthesised components. The computed energies SyN after weighting wN according to characteristics of the earpiece 3 are combined (17) to give an estimate ET of the energy-content of the signal-sample. Comparison (19) of the estimate ET with itself before and after application of a non-linear function (18) produces an attenuation factor that is applied (20) to limit the signal supplied to the earpiece 3. DTMF-tone detection (6) uses synthesis by LMS filter 25 of the sample-signal at DTMF-tone frequencies, and sorting (27) of their computed energies Sy1-8. The presence of DTMF tones in the sample-signal is detected if signals cS6-cS8 representing the three highest energies are found (31) to satisfy three criteria (28-30) attributable to the presence of DTMF-tone pairs.

Title: Gas sensors
Inventor: HOPKINS GRAHAM PAUL
IPC: G01N21/03
Filed: 2003-11-07
Abstract: A gas sensor of the type having a housing defining a chamber within which light is transmitted from a source to a detector through an optical path, includes internal mirror portions having part ellipsoidal shape. Light is transmitted from a source to a detector via the reflective portions. The detector is arranged to sense light only from a limited range of angles, such that only light transmitted through a defined optical path reflected off the two reflective portions from the source reaches the sensor. This ensures that there is a constant optical path from the source to the detector, which improves the signal to noise ratio of the device.
