Patent GB-2370362-A (GB)
Title: Method for testing a circuit
Inventor: FIRTH STEPHEN
IPC: G01R31/3183
Filed: 2000-08-04
Abstract: A method for testing a circuit comprises the steps of applying an input reference signal 4 to the circuit and providing an output reference signal 6a from one of the outputs of the circuit. The timing of the output reference signal is defined independently of the input reference signal by selecting a parameter a, which represents the time between a selected point in the output reference and, for example, an edge transition. The other outputs of the circuit 6b, 6c are then defined by means of equations based on the parameter a. The output reference 6a is thus used to define the time delays of the circuit independent of the input signal. The method may be particularly useful in testing circuit designs before they are finalised.

Title: Handling requests for documents from a database
Inventor: KARAEV ISAAK
IPC: G06F21/31
Filed: 1997-05-29
Abstract: Distributing documents over the world wide web (www). A database on a central sewer stores research documents from a number of contributors (eg authors). Requests for documents received from remote computers are handled using document profiles and authorisation groups corresponding to the contributors of a document. For each user, a list of accessible groups is stored, defining which authorisation groups of documents the user is permitted to access. In a further embodiment, the number of documents that meets a search query is limited to a set count. If the count is exceeded, and no time range is specified then a default time range is imposed.

Patent GB-2387996-A (GB)
Title: Wireless communication network with automatic threshold adjustment
Inventor: BUSCH PATRICK
IPC: H04B7/005
Filed: 2002-04-23
Abstract: A wireless communication network contains a plurality of spatially distributed communication devices (access point devices and station devices) for exchanging wireless signal frames. A device processes signal frames only when a strength of the signals exceeds a carrier detection threshold. Devices defer an intended transmission upon detection of a wireless signal with a strength greater than a defer threshold prior to the intended transmission. A measuring circuit performs a first measurement of a first signal strength of signals from access point devices and a second measurement of a second signal strength of signals from station devices associated with a first one of the access point devices. A threshold adjustment circuit first sets the carrier detection threshold of the first one of the access point's stations above the first signal strength. The second measurement is performed when said first setting has taken effect. The threshold adjustment circuit subsequently setting the defer threshold of the first one of the access point stations and/or one or more of the station devices associated with the first one of the access point devices below the second signal strength.

Title: Servo motor drive control system
Inventor: SANO SHUYA
IPC: H02P5/54
Filed: 2000-12-19
Abstract: A servo motor drive control system comprising a command unit, e.g. a numeric controller, a plurality of drive controllers for controlling the drive of a servo motor, a first communication line for transmitting data, e.g. a control command, from the command unit to the drive controllers, and a second communication line for transmitting data, e.g. detection data, from the drive controllers to the command unit and adapted for controlling the servo motor synchronously by communicating data among the drive controllers through the communication lines, wherein the cycle of communication among the drive controllers is 1/n (n is an integer) that of the command unit. Since an synchronism error correction control command can be transmitted at high speed from one drive controller to another drive controller without being restricted by the control cycle of the command unit, no operation load for generating a synchronism error correction control command is imposed to the command unit, and the synchronism error due to a disturbance, e.g. an impulse, can be converged in a short time.

Title: Testing unit for an infrared or radio frequency key fob
Inventor: APPLEBY STEVEN
IPC: G01R29/10
Filed: 2003-05-14
Abstract: A testing unit comprises an antenna to detect radio frequency (RF) radiation and an infrared (IR) detector D1, such as a diode, to detect IR radiation. The outputs of the detectors are passed to a comparator circuit IC1b. In a start up step, a microcontroller generates a square wave of increasing amplitude and duty cycle that charges capacitor C3 and raises the DC voltage across the antenna and detector until the output of comparator IC1b changes. The value of the square wave that causes this change is stored. In use, the device is used to test a RF or IR transmitting key fob e..g. for a vehicle remote locking system. The radiation emitted by the key fob increases the voltage across the antenna and detector and consequently a different value of square wave to that in the start up step is required to change the output of comparator IC1b. The difference in the two square wave values is computed and displayed via an array of light emitting diodes.

Title: A method and apparatus for saving power in dynamic circuits
Inventor: GEDAMU ELIAS
IPC: G06F1/32
Filed: 2003-07-17
Abstract: An embodiment of the invention provides a circuit and method for reducing power in dynamic circuits. A large single pre-charge FET (432, 434) is used to pre-charge the pre-charge nodes of all dynamic logic blocks (400, 402, 404, 406) contained in a plurality of dynamic logic blocks. The large single pre-charge FET replaces all smaller individual FETs that normally would be used. Because smaller FETs typically have more subthreshhold leakage than larger FETs, the overall subthreshhold leakage is reduced. The large pre-charge FET only replaces smaller pre-charge FETs that have the same pre-charge signal going to their gates.
