Patent GB-2324418-A (GB)
Title: Electrical pickup device
Inventor: WATSON HUGH JOHN
IPC: H01R41/00
Filed: 1997-04-17
Abstract: A means of conducting electricity, between a series of conductors and an electrical load, via an array of contacts, which operates irrespective of the position or orientation of the contact array on the conductors. The set-up consists of three parts. An area of conductive strips, where each strip is of opposite polarity to the ones adjacent to it, and the distance between each strip is slightly greater than the diameter of the contacts. An array of six contacts is mounted in a radial pattern. And a rectifying circuit shown in Fig.3. When the contact array is placed on the area of conductive strips as shown in Fig.4, the spacing of the contacts relative to one another in the array ensures that, at least one contact is always touching a negative conductor and at least one contact is always touching a positive conductor. The rectifying circuit allows each contact to supply either the positive or negative load, depending on which polarity of conductor it is touching, thus ensuring a continuous flow of electricity even if the contact array is moved around the area of conductors.

Title: Reducing skew in signal carrying cables, conductors
Inventor: WEATHERLEY RICHARD
IPC: H04L25/14
Filed: 1997-08-22
Abstract: Skew or transit time delay may occur in a cable used e.g. for high speed data transmission and comprising a plurality of pairs of twisted conductors with each pair having different twist to avoid crosstalk. Such skew may be reduced or eliminated by transferring signals of a first conductor and a second conductor respectively to the second and first conductors at a position intermediate the ends of a data cable. The transferring of the signals is such that in travelling the length of the cable, any one of the signals travels partly on the first conductor and partly on the second conductor. In order to ensure that a signal injected at one end of a particular conductor arrive at that conductor at the other end, a further swapping of the signals is preferably provided. A cable including a multiplicity of twisted pairs may be cut up at appropriate points and reconnected via plugs and socket-socket connectors. The invention is also useful for reducing skew between the individual conductors of a particular pair of conductors.

Title: RF transmitter amplifier with Cartesian feedback and use of test DC offsets to reduce carrier breakthrough
Inventor: WESTALL MARCUS ANTONY
IPC: H04L27/36
Filed: 1997-09-09
Abstract: An RF transmitter employs negative feedback to reduce non-linearities in power amplifying means 18 to 21 and, since the transmitter received as input I and Q components, a Cartesian Loop is provided, by means of which a signal derived from the output of the amplifier by a probe 22 is split into de-modulated and Q components in order to provide feedback signals at 27 and 28. Unfortunately the negative feedback cannot correct for errors in the feedback loop itself, and component imperfections introduce a DC offset into the feedback loop. The modulation is suppressed carrier but the DC offset re-introduces the carrier. The invention provides a method of reducing the DC offset to reduce the carrier breakthrough by injecting known DC offsets into the I and Q inputs and measuring the resulting ripple in the output of the power amplifier means corresponding to the re-introduced carrier, enabling calibration offset DC levels to be calculated and injected into inputs 27, 28.

Title: False-synchronisation detection for a DQPSK demodulator
Inventor: NOBUSAWA HIDEAKI
IPC: H04L27/22
Filed: 1998-05-22
Abstract: A false-synchronisation detection device for a n/4 shift DQPSK (Differential Quaternary Phase Shift Keying) demodulator comprises a bidirectional counter which counts towards a predetermined value at a first rate when the sense of phase changes in former and latter halves of a symbol interval are different, and counts away from the predetermined value at a second rate, lower than the first, when the sense of phase changes are the same. The device recognises false synchronisation when the count equals the predetermined value. Preferably, the counter also counts away from the predetermined value when the sense of phase change in the former half of a symbol interval is the same as the sense of phase change in the latter half of the preceding symbol interval. The device provides quick detection of false-synchronisation even when there are consecutive data patterns producing phase changes in the same direction.

Title: Method for controlling the cavity lamp of a microwave oven
Inventor: PARK HEUI-JUNG
IPC: H05B6/66
Filed: 1998-06-19
Abstract: A method for controlling a cavity lamp of a microwave oven determines whether a door is opened 10. A cooking state is identified by determining whether a cooking key of a key input portion is selected when the door is opened 11. Whether the cooking cancellation key of the key input portion is selected in the cooking state is identified 12. The cavity lamp turns off when the cooking cancellation key is selected. Otherwise an open time of the door passes beyond an established predetermined time in advance is determined. The cavity lamp is turned off when the open time of the door passed beyond the predetermined time. Therefore, the cavity lamp which is turned on when a door is opened is turned off automatically or manually so that life of the cavity lamp is lengthened and loss of electric power is reduced.

Patent GB-2329177-A (GB)
Title: Winding up a web
Inventor: MEYER HELMUT
IPC: B65H18/26
Filed: 1998-08-18
Abstract: In a method of winding up a web (3), onto a winding core (4) to form a reel (2) the web is fed over a contact roll (1) fitted in a movable carriage (5) and, in the case of contact winding, is pressed against the reel (2) with a predefined contact pressure. The carriage (5) is driven by a three-phase servomotor (7) that is arranged in a rotatably mounted drive unit (6) and, depending on the reel diameter, is moved into a desired position. The contact pressure of the contact roll (1) on the reel is applied by the predefined cylinder pressure of a short-stroke cylinder (16) that is connected to the rotatably mounted drive unit (6). In the event of a displacement of the carriage (5) from its desired position, the drive unit (6) is rotated and, as a result, the position of the piston (15) in the short-stroke cylinder (16) is changed. Depending on the rotation of the drive unit (16), the carriage (5) is moved back by the three-phase servomotor (7) into the desired position, and a predefined desired position of the piston (15) in the short-stroke cylinder (16) is set again.

Title: Reduction of imbalance in transmsit queues in a network switch
Inventor: GIBSON PATRICK
IPC: H04L47/52
Filed: 1999-04-21
Abstract: A network switch receives addressed data packets and distributes at least some of them into a group of packet queues QA, QB, QC, QD. At least one packet is read out from each queue in turn in a cyclic sequence. A threshold length is defined for each queue such that when a queue length is above its threshold a greater number of packets are transmitted and when the queue length is below the threshold a lesser number of packets are transmitted. More than one threshold 51, 52 may be defined for each queue and the number of packets transmitted from each queue in its turn in the cyclic sequence may progressively increase as the length of the queue exceeds each successive threshold. The address data may be subject to a hashing algorithm. A threshold for each queue may be individually dynamically adjusted according to rate of input traffic, instantaneous queue size or other traffic statistics.
