Title: Mounting SiC rectifiers in an AC generator
Inventor: UMEDA ATSUSHI
IPC: H02K11/04
Filed: 1996-06-06
Abstract: To provide a low-loss vehicular AC generator (200) in which a rectifier (19) is mounted on a front side of a transversely-mounted engine (100) with a front exhaust pipe (101) layout and fixed to an exhaust pipe-side end wall of the housing (1, 2) of the generator (200), a three-phase full wave rectifier (19) employs MOS power transistors (19a-19f) formed of monocrystalline SiC as semiconductor rectifying devices. The rectifier (19) is fixed to an exhaust pipe-side end wall of a generator housing (1, 2). This construction considerably reduces the heat generation of the rectifier (19) and enhances its heat resistance, so that the disposal of the rectifier (19) on the exhaust pipe-side end wall of the generator housing (1, 2), which is a severe thermal environment due to radiant heat from the exhaust pipe (101), will not degrade the reliability of the rectifier (19).

Patent GB-962659-A (GB)
IPC: G08B13/24
Abstract: 962, 659. Burglar alarms. MOSLER RESEARCH PRODUCTS Inc. Oct. 10, 1960, No. 34686/60. Heading G4N. In a burglar alarm system, a transmitting' antenna connected to a radio frequency transmitter is placed at the perimeter of an area to be protected and receiving ante@ae are placed in the vicinity of the transmitting a nna so that variations in the field pattern caused by the proximity of an intruder can be detected and used to operate an alarm. An earthed chain link fence 14 (Fig. 2) surrounds the area to be protected. A transmitter 2, (Fig. 3 not shown), operating at a frequency of 15 to 30 kc/s, feeds a horizontally arranged antenna 1 via a loading coil 13, while receiving antennae 3 a - e, 4 a -e, are equally spaced vertically or horizontally from antenna 1. Detectors 15 a - e are arranged as shown in a number of zones into which the perimeter has been divided and they feed corresponding guard panels 9 a - e at a central control station 12. The detector circuit (Fig. 4) consists of a balanced network 30, 31, 32 driving a transformer 33, the outputs from which are rectified and smoothed and then passed to a line relay 40 in the guard panel. When switch 42 is in the "Day" position an increase in current through one of the coils 39 of relay 40, causes contacts thereof to be operated and hence lamp 49 to be lit. Coils 39 are arranged so that a small unbalance current is required in order to keep the relay contacts unoperated, hence in the event of transmitter failure or a break occurring in any of the antennae, the relay will still operate and cause an alarm to be given. In the "Night" position of switch 42 an increase of voltage on either terminal 1<SP>1</SP> or 2<SP>1</SP> will cause alarm relay 36 to operate followed by slave 43 thus actuating an audible alarm 47 or lamp 46, (relay 40 in this case does not operate). Relay 36 must be reset manually, so that once operated the alarm will continue to be given. An automatic resetting device is described in conjunction with Fig. 5 (not shown) and various methods of arranging the antennae are disclosed (Figs. 6-13 not shown).

Title: Modelling a system with more parameters than sensors
Inventor: DADD GRAHAM JOHN
IPC: G05B23/02
Filed: 1997-02-04
Abstract: A method of tracking a system (1) having sensors (3) (e.g. gas turbine engines) by providing a computer model (4) which, from changes in sensor readings, can track (follow) changes in performance parameters of the system. These may be e.g. efficiencies of various of components such as compressors and turbines. In the common embodiment, the method used (Singular Value Decomposition) is a way of computing the most likely solution when there are more performance parameters than the number of sensors used and thus a degree of redundancy. The method allows system diagnosis and most importantly a tracked model allows the selection of a tailored control regime (9) which results in optimum efficiency for the individual system (engine).

Title: Speakerphone
Inventor: KARNOWSKI MARK J
IPC: H04M9/08
Filed: 1996-05-30
Abstract: In a speakerphone, which operates under software control, transmit and receive signal levels are sampled and compared against one another, with hysteresis, to enable one of two speakerphone modes of operation - either a transmit mode or a receive mode. A single peak detector 146 is multiplexed to sense the transmit and receive signal levels. Fixed attenuators 134,138 are switched into either the receive signal path or into the transmit signal path, depending upon the current speakerphone operation mode. Signal compression is used to provide for improved mode determination over a wide dynamic range. The level detection and/or attenuation may be performed in software. The speakerphone functions are readily implemented using standard line interfaces and control circuitry. Automatic gain control in the receive mode ensures a constant level of signals at the speakerphone loudspeaker 152, regardless of telephone line conditions.

Title: Layering cache and architectural-specific functions to permit generic interface definition
Inventor: ARIMILLI RAVI KUMAR
IPC: G06F12/08
Filed: 1998-03-27
Abstract: Cache and architectural functions within a cache controller 202 are layered and provided with generic interfaces 220-230. Layering cache and architectural operations allows the definition of generic interfaces between controller logic 212-218 and bus interface units 204,208, within the controller. The generic interfaces are defined by extracting the essence of supported operations into a generic protocol. The interfaces themselves may be pulsed or held interfaces, depending on the character of the operation. Because the controller logic is isolated from the specific protocols required by a processor or bus architecture, the design may be directly transferred to new controllers for different protocols or processors by modifying the bus interface units appropriately.
Patent GB-2344177-A (GB)
Title: Detecting vibration of turbine blades
Inventor: TAYLOR JOHN
IPC: G01H1/00
Filed: 1998-10-19
Abstract: A method of monitoring a turbine blade B by measuring its arrival time at a given position over a plurality of revolutions where the variation of the elapsed time between successive passages is used to determine the presence of vibration. A capacitive probe P may be used to generate an output pulse for each passage of the blade and the phase variations of the resulting signal may be examined. The data may be analysed using differentiation, the fitting of a polynomial function to the probe output and/ or by use of a Fourier Transform to derive frequency and phase information. Torsional vibration may be distinguished from flapping by moving the probe longitudinally to compare the arrival times of spaced-apart regions of a given blade (figure 5).

Title: Defining transmission power according to previous transmission powers
Inventor: KOSKELA MARKO
IPC: H04B7/005
Filed: 1998-10-30
Abstract: In a TDMA (Time Division Multiple Access) cellular system offering broadband services and in which the number of time slots to be used for data transfer can be changed during the connection, the transmission power of a new time slot is defined in the mobile station on the basis of the transmission power of at least one other time slot used in the connection. If the connection has had one time slot for its use when a new time slot is being allocated, the transmission power of the new time slot is preferably set to the same value as the previous time slot. If the connection has had two or more time slots for its use when a new time slot is being allocated, the transmission power of the new time slot is preferably defined on the basis of the transmission powers of these other time slots according to a previously defined algorithm. As the algorithm, a minimum value, a maximum value or an average value can preferably be used.

Title: Nuclear spectroscopy signal processing system
Inventor: JURION BRUNO
IPC: G01V5/12
Filed: 1997-08-28
Abstract: Image pulses produced when nuclear particles or gamma rays are incident on a detector are sampled at a constant frequency to produce a digital image of the pulse. A pulse is determined to be valid if the amplitude of more than a preset number of consecutive samples exceed a threshold. The pulse length is adjusted 25,26 by comparing the ratio of pulses having x consecutive valid samples eg 5 to the number having x+1 consecutive valid samples eg 6. Alternatively the subsequent analysis of the set of samples is determined in accordance with the amplitude of the largest sample in the pulse or the time taken by the pulse to reach that peak value. The threshold for a valid sample or the number of samples in a valid pulse may be set in accordance with the maximum amplitude of the samples in a pulse. The length of the pulse can be determined by counting the number of consecutive valid samples in that pulse. The pulse shape can then be regulated based on the average pulse length. Also disclosed is a system to identify and reject pile-up pulses when the number of consecutive valid samples is greater than a predetermined number. Pile-up can also be determined upon comparison of the area under the valid samples with a number of predetermined pulse shapes, by comparing a predicted change of amplitude between adjacent valid samples with an actual change or if the time between the first valid sample of a pulse and the maximum value exceeds a set time. The ability to be able to determine the time of arrival of a pulse is also envisaged.
