Patent GB-2344721-A (GB)
Title: Handover determination and power control adjustment in mobile communications systems with frequency hopping
Inventor: SANCHO FERNANDO
IPC: H04B7/005
Filed: 1998-12-10
Abstract: A device (5) for triggering a handover or for adjusting transmit power levels in a cellular communications system distinguishes between the use of a frequency hopping or a non-frequency hopping channel and sets a different threshold value depending on which type of channel is being used. In one embodiment, handover trigger levels for hopping channels are based on frame erasure rate measurements rather than bit error rate measurements thereby avoiding unnecessary handovers and advantageously reducing signaling traffic.

Title: Distributing addressed data packets
Inventor: CREMIN CON
IPC: H04L47/52
Filed: 1999-02-24
Abstract: A device for distributing addressed data packets from an input channel to a multiplicity of packet queues comprises FIFO buffers 14a-14d for defining the queues, a demultiplexer 13 for receiving the addressed data packets and responsive to first hashed addresses to distribute the data packets to the queues. A select hash logic 12 applies a default hash function derived from memory 18 to the address data of each of the addresed data packets. At the same time, a succession of different hash functions from external memory 19 is applied to the address data in each of the packets to produce second hashed addresses and occurrences of these addresses are counted at 23a-23d to obtain for each of these different hash functions a respective one of a plurality of set of counts. Each such set represents the distribution of the packets that would occur in the queues if the respective one of the different hash functions had been applied to the addressed data packets. The sets of counts are analysed to determine which one of them represents a best distribution of the packets and the hash function associated with the best distribution is applied to incoming packets in place of the first hash function.

Patent GB-2350449-A (GB)
Title: Detecting replication of a computer virus using a counter virus
Inventor: LUKE JAMES
IPC: H04L9/00
Filed: 1999-05-27
Abstract: A counter virus agent for detecting viral infection of a computer system. The agent identifies potential host files for the agent within the computer system, and controls replication of the agent within the host files so that it is maintained at a predetermined population level, whilst moving its presence around the file system. When instantiated within one of the host files, the agent determines the population of the counter virus within the computer system. When the predetermined population level is exceeded, possible viral infection of the computer system is indicated, since the counter virus is designed so that it is replicated along with the malicious virus. This replication can be ensured simply using a macro virus to detect unauthorised macro viruses; however with executable code viruses, which replicate by copying only a specific number of bytes into an uninfected file, the counter virus agent must amend the unauthorised virus to ensure that it is successfully copied along with it, for example by compressing the virus and the counter virus.

Title: Communication switch including input throttling to reduce output congestion
Inventor: DRUMMOND-MURRAY JUSTIN ALEXAND
IPC: H04L47/30
Filed: 1999-08-12
Abstract: A switch for a data communication system includes a multiplicity of ports 1-4 operative to receive (11-14) data packets; a multiplicity of ports operative to transmit (41-44) data packets, means for storing (51-54) data packets prior to transmission from the ports that are operative to transmit data packets, said means establishing respective transmit queues of data packets for the ports that are operative to transmit data packets; and means 37,38 for establishing measures of the contribution of each of a plurality of ports that are operative to receive data to the queue of data for each of the ports that are operative to transmit data. The switch is characterised by a control process which responds to said measures and to an indication that a queue of data packets for a port operative to transmit data is excessive. The process identifies at least one port that provides data packets to said excessively long transmit queue and enables means 21-24 for providing flow control to a device which is coupled to the identified port 1-4. This is done using MAC control frames and a leaky bucket counter, Fig.5, (not shown). The control frame signals a reduction in the supply of data packets to the device coupled to the identified port.

Patent GB-2342876-A (GB)
Title: Methods of manufacturing rotary drill bits
Inventor: EVANS STEPHEN MARTIN
IPC: B22F7/06
Filed: 1999-10-13
Abstract: A rotary drill bit is manufactured by a powder metallurgy process by placing a metal mandrel 54 in a mould 38, packing the mould 38 with particulate matrix-forming material 50, infiltrating the material with a molten binding alloy, and cooling the assembly to form a solid infiltrated matrix bonded to the mandrel 54. The mandrel 54 comprises an outer part 56 surrounded by the matrix-forming material 50 and an inner part 58, secured to the outer part 56 but out of contact with the matrix-forming material 50. The outer part 56 of the mandrel 54 is formed from a material having thermal characteristics close to those of the matrix, so as to reduce the tendency for the matrix to crack under the thermal stress, while the inner part 58 of the mandrel 54 is formed from a precipitation-hardening material, the strength and hardness of which increases in the infiltration process and the subsequent heating/cooling cycle for brazing the cutters 24 on to the drill bit. A threaded connection region of the drill bit may be formed directly on the inner part 58 since it will have sufficient strength and hardness for this purpose.

Title: Reaction mechanism for a booster
Inventor: KOBAYASHI KAZUO
IPC: B60T13/573
Filed: 1997-05-28
Abstract: A booster, eg. for a brake or a clutch, has a power piston 104 for driving an output shaft 124 in dependence on the displacement of a valve plunger 111 by means of a brake pedal. The braking reaction passes via output shaft directly to valve body 130, and, as a consequence, in order to provide "feel", a spring 139 in the constant pressure chamber 106 imparts a reaction, via the valve plunger, to the brake pedal. The reaction imparted preferably has a reduced rate of increase to the brake pedal when a travel of the pedal is small, and an increased rate of increase when a travel is higher.

Title: Enlargable suitcase for stocking clothes and hanger mechanism to it
Inventor: FRANKLIN DANA
IPC: A45C3/00
Filed: 1992-02-19
Abstract: Past garment bags have included expansion features such as a peripheral zipper in the rail portion to permit the garment bag to expand to accommodate a greater number of clothes. A hanger bar for supporting clothes on hangers has also been provided which has a collapsed condition for supporting few hangers, and an expanded condition for supporting a greater number of hangers corresponding to the expanded condition of the garment bag in which the hanger bar is suspended. Such hanger bars have failed to include an effective means for holding the hooked portions of ordinary closet-type hangers in either the collapsed or expanded condition of the hanger bar. Disclosed is such a garment bag with a hanger bar having hanger retaining means which is effective whether the hanger bar has a shortened length corresponding to the collapsed condition of the garment bag or a lengthened condition corresponding to an expanded condition of the garment bag. In particular, an L-shaped retainer is carried by a first telescoping section of the hanger bar and operates simultaneously to keep hangers from falling off the front end of the hanger bar and from being dislodged upwardly away from the hanger bar. <IMAGE>

Title: Detonating cord connector for non-electric blasting assembly
IPC: F42D1/04
Filed: 1982-04-26
Abstract: A percussion-actuated instantaneous or delay detonator transmits a detonation from a first length of low-energy detonating cord (LEDC) transversely positioned adjacent the detonator's percussion-responsive end to a U-shaped segment of a second length of LEDC held with its apex against the base-charge end of the detonator and the arms of the U extending away from the detonator.
