Title: Seat belt retractor with varying winding characteristics
Inventor: FUJII HIROAKI
IPC: B60R22/48
Filed: 2000-01-19
Abstract: A seat belt retractor whose winding characteristics, e.g. tension, are controlled by means of signals received from various sensors comprises, a base frame (3 in figure 1), a spool (2), and a motor (5). Webbing (W) is wound around the spool by the motor through a speed reduction mechanism 10, which includes first and second reduction gear transmission trains (10A and 10B in figure 7) having different reduction gear ratios. Switching means 70 is provided for switching between the two transmission trains corresponding to signals received from signal sensors, and a resistant torque means 60 having a preset value so that one of the transmission elements common to the said trains transmits rotation of the motor to another of the transmission elements common to the said trains when the torque of rotation is smaller than the preset value. It is possible for there to be a different number of transmission trains, and for a return spring to be used in conjunction. There is also provided a control method for defining different operating conditions which is dependent upon the signals received from the various sensors.

Title: Applying downlink weights to an adaptive antenna array
Inventor: VILLIER ERIC
IPC: H04W16/24
Filed: 2000-05-12
Abstract: A base transceiver station 8 includes an adaptive antenna array for radiating a beam of energy 10 in the direction of a mobile station 12. The base transceiver station may estimate the position of the mobile station based upon estimates of both the angular spread of multipath signals received from the mobile and the direction of mobile relative to the base transceiver station. The angular spread and direction may be used to define a spatial sector in which the mobile is believed to reside and a set of downlink weights may be computed so that the antenna array produces a beam with sufficient angular spread to cover such a spatial sector. The downlink weights may be complex weights and may be calculated using discrete spheroidal prolate sequences.

Title: Transmitting differentially encoded data
Inventor: RAYNE MARK WENTWORTH
IPC: H04N7/167
Filed: 2000-07-07
Abstract: A transmitted video data bit stream contains a stream of I, P and B frames, I frames being complete data frames and P and B frames being differentially coded data frames. I frames are sent less frequently in the stream than P and B frames because they contain more data. Encryption synchronisation frames are also transmitted throughout the transmission at intervals and together with the I frames allow users to join the transmission after the start and allow recovery from transmission errors. Encryption synchronisation frames 9 are sent immediately prior to I frames 8. This ensures that, no matter where a user begins receipt of the data bit stream 20, both an encryption synchronisation frame 9 and I frame 8 will be received in quick succession and decoding will commence with a minimum delay between receipt of the encryption frame and receipt of the I frame. The synchronisation frames 9 may also be sent at other rates, intervals or positions in the data stream in a predetermined relationship to the I frames.

Title: An egress hinge for a vent
Inventor: BRAIN CLIVE
IPC: E05D15/30
Filed: 2000-08-10
Abstract: A hinge for supporting a vent between a closed position, an intermediate position and a fully open position comprises, a slider 3 mounted in a support track 1, a vent arm 7, a control link 15 joining the slider 3 to the vent arm 7, and a restricting link 27, wherein the restricting link 27 acts between the vent arm 7 and the control link 15 to restrict the opening of the vent arm 7 to an intermediate position. The control link 15 comprises a slot 101 that is engaged by a retaining stud 105 located on the retaining link 27. The slot has a widened portion 103 that allows the retaining stud 105 to be disengaged from the slot 101. At one end of the slot is an opening controlled by a spring gate 107. In use the retaining stud 105 is engaged in the slot 101, restricting the opening of the vent to an intermediate position. To open fully the vent arm 7 is moved to a position such that retaining stud 105 is disengaged via the widening 103 in the slot 101, allowing the vent arm 7 to be fully opened. On closing, stops 119 and 117 on the vent arm 7 force the retaining stud 105 to align with and engage the slot 101 via the spring gate 107. Alternatively the slot 101 may be located in the restricting link (27 fig 5) and the retaining stud (207 fig 5) on the control link. In a further embodiment the retaining stud 105 is spring biased such that on closing the vent it is depressed and enters the support track 1.

Title: An ophthalmoscope or retinoscope with electroluminescent light source
Inventor: WILLIAMS WILLIAM J
IPC: A61B1/06
Filed: 2001-06-29
Abstract: An ophthalmoscope or retinoscope has a means for supplying electrical power (a), a means for controlling the electrical power (b), a means for generating light based on electroluminescent or phospholuminescent technology (c), a means for transforming the light prior to illumination of the structure under scrutiny (d) and a means for transforming the light returning from the structure under scrutiny (e). The light generating means (c) is based on electroluminescent technology and is preferably an LED. Some or all of the components (a), (b), (d) or (e) are designed for incandescent filament bulbs. Thus a conventional incandescent type ophthalmoscope or retinoscope is adapted to use an electroluminescent light source. The use of an LED in place of conventional incandescent filament technology reduces power consumption, simplifies construction as there is not need for a heat sink, and enables a more light weight instrument to be produced. Further improvements include an extended life of the light source, reduced infra red emissions, simplification of optics design and improvements in colour temperature, light flux directionality and adaptation of light flux directionality.

Title: Acoustic fluid measuring system using multiple echoes
Inventor: ATKINSON HARRY
IPC: G01F23/28
Filed: 2002-09-09
Abstract: An aircraft ultrasonic fuel-gauging system has a processing unit 7 that energizes probes 3 and receives signals from transducers 4 arising from energy reflected back from the fuel surface 10. In addition to determining the time between transmission of a signal from the transducer 4 and reception of its reflection from the fuel surface, the processing unit 7 also determines the time of reception of subsequent reflections caused by reflection back from the lower end of the probe. The processing unit 7 determines whether the subsequent reflected signals are within predetermined limits of the time interval between transmission and reception of the first reflected signal in order to confirm the validity of the first signal. The processing unit 7 also counts the number of subsequent reflected signals received within predetermined time intervals to assign a confidence level and this used to select between different incompatible signals, such as signals from that probe at different times or signals from different probes.

Patent GB-2380268-A (GB)
Title: Reflective light diffuser
Inventor: CLABBURN ROBIN JAMES THOMAS
IPC: G02B5/02
Filed: 2001-05-03
Abstract: A reflective diffuser of light in one embodiment comprises an extruded, drawn, rolled or otherwise stretched or extended sheet comprising a matrix of a first plastics material incorporating inclusions of a second, different material, substantially insoluble in the first material, resulting in small scale surface irregularities on at least one surface of the sheet. The textured surface having such irregularities is rendered reflective or partly reflective, for example by metallisation, eg. by vapour deposition or other particle deposition of metal, such as vacuum sputtering. By controlling the extent to which the sheet is stretched preferentially in one direction during manufacture, the extend to which the diffuser has asymmetric diffusing properties can be readily controlled. Instead of metallising the extended sheet itself, the textured surface of the latter may be used as a mould or die surface for the production of a textured surface on another, e.g. plastics sheet which may then be metallised or the textured surface of the extended sheet may be used as the progenitor of a mould or die surface for the production of such plastics sheets bound for metallisation to form reflective diffusers. Reflective light diffusers according to the invention may be used, for example, in LCD displays as back reflectors.
