Patent GB-2307043-A (GB)
Title: Liquid level determination
Inventor: JOLLEY JOHN D R
IPC: G01F23/292
Filed: 1995-11-07
Abstract: The method and apparatus involves directing a beam of radiation from a first emitter (9a) at a vessel (7) containing a liquid, and detecting by means of a first detector (9b) whether the beam is deflected by the upper surface of the liquid. This gives information concerning the level of the liquid. A second emitter (10a) and a second detector (10b), at a higher location than the first emitter (9a) and detector (9b), may be used to give additional information.
Patent GB-2296616-A (GB)
Title: Setting up distance measurement device
Inventor: ODA HAJIME
IPC: G01S7/486
Filed: 1995-11-22
Abstract: Device 1 measures the distance to target T and assigns it to one of three range bands. By means of inputs 3 and 4 a user first sets the distance to a reference point in the measurement range of the device, and then sets the boundaries of the range bands relative to this reference point. This has the advantage that if the device is knocked or moved, only the distance to the reference point needs to be reset in a single operation; all the boundaries are then reset automatically. The reference point may be a boundary, or midway between the boundary points. Application to conveyor belts or traffic monitoring is mentioned. <IMAGE>

Title: Path controlled repeating mobile stations
Inventor: STEELE RAYMOND
IPC: H04B7/26
Filed: 1997-06-05
Abstract: A radio communications network comprises at least two base stations in fixed relatively widely spaced-apart positions, and a plurality of relatively closely spaced-apart mobile stations. At least some of the mobile stations act as controlled repeaters to relay traffic signals from a relatively close mobile station to another relatively close mobile station under control of a central control means. The central control means estimates the positions of the mobile stations in order to determine one or more virtual paths for the traffic signals. Control messages telling each mobile station to repeat the call are transmitted to each mobile station via one of the base stations without the use of repeaters. Packet data may be sent over a plurality of virtual paths with different data rates. Base stations may be fixed terrestrial stations, earth-orbiting satellites or aerial stations. The mobile stations may be situated on marine vessels.

Title: Method for simulating hazardous material detection
Inventor: PIKE STEVEN DEREK
IPC: G09B9/00
Filed: 1996-09-19
Abstract: A method for training operators in the proper use of a hazardous material detector comprises, providing simulated hazardous material and a simulated detector that detects and responds to the simulated hazardous material. The simulated detector contains information concerning the correct method of using the detector and monitor errors made by the trainee operator. The simulated hazardous material may transmit an identification signal that contains information concerning the nature of the hazardous material. A remote device may be used that allows an instructor to change the way the simulated detector responds to the simulated hazardous material. The device that simulates the hazardous material may be either; a passive radio identification device, with or without a magnet; a magnet alone; or an ultrasound emitter. The system is particularly useful for training operators in the detection of hazardous materials including radioactive, biological or chemical weapons agents, or hazardous environments, for example, in areas where oxygen levels are depleted.

Patent GB-2333916-A (GB)
Title: A phase detector
Inventor: POPPLEWELL Andrew
IPC: H03L7/091
Filed: 1998-01-09
Abstract: A phase detector detects 5 an error value dependent on the relative phase between a local oscillator signal 7 and an input signal 8 having a partial response characteristic. Such detectors are used in systems which recover data from noisy channels, eg magnetic data couriers having high data densities. The detector determines the difference between an ideal sample value and an actual sample value for several sampling points, and determines the sense of change to a given ideal sample value from an ideal value for a preceding sample point, and utilises that information to provide the required error value. The phase detector 5 is described in detail (Fig 3).

Title: Voice mail system
Inventor: MISTRY NITA
IPC: H04Q3/72
Filed: 1998-02-16
Abstract: Voice Mail systems allow callers to leave voice message to the individual's voice mailbox, if the person being called is not available for any reason. With this invention, these voice messages can be processed by a voice recognition system and converted into a textual form for display, print or to be forwarded to their E-mail box. To use the existing networked print and E-mail facilities of the business premise, the Voice mail system would have to be configured to the Local area Network (LAN) technology, to address the local printers and the E-mail system. The Voice mail system would also have a database of printer ids and E-mail id's associated with the individual's voice mailbox. The user can retrieve messages either by listening or using display facilities of the telephone unit. Additional caller details can be captured using the current digital network technology which enables the capture of the calling party number and the time and date (time stamp) when the voice message was received.

Title: Converting luminance-chrominance colour space signals to RGB colour space signals
Inventor: SHYU RONG-FUH
IPC: H04N9/67
Filed: 1998-02-19
Abstract: For converting digitized luminance-chrominance color space signals to digitized RGB colour space signals, starting terms of a standard set of conversion equations are expanded into linear combinations of terms that involve only two coefficients. Two code generators (2, 3) respectively generate transformation codes that correspond to a first one of the chrominance colour space signals during a first timing phase and a second one of the chrominance colour space signals during a second timing phase. The transformation codes from the code generators (2, 3) are linearly combined to obtain transformation values for the starting chrominance-in-colour terms. One code generator (2) may multiply the colour space signals by 1.402, 0.714, 0.357, 1.428 and 0.714 in different embodiments, the other code generator (3) multiplying the colour space signals by 0.013, 0.013, 0.013, 0.013 and 0.344 in the different embodiments.
