Patent GB-2162314-A (GB)
Title: Transducer
Inventor: GREENWOOD J C
IPC: G01P15/18
Filed: 1985-07-24
Abstract: A transducer for stress or strain measurement comprises a pair of parallel stretched silicon filaments 12 which vibrate in antiphase in their common plane. The resonant vibrational frequency is determined by the external forces applied to the filaments. The transducer may be employed as a sensor element in an inertial guidance system. The filaments form a double-ended tuning fork structure attached at its roots 13, 14 to a single crystal silicon support 11 having flexible regions 15 by which external forces are applied to the filaments. Piezoelectric layers or electrostrictive pn junctions at the roots 13, 14 establish filament vibration which may then be detected electrically or optically. <IMAGE>

Patent GB-2174835-A (GB)
Title: Position counting method and apparatus for use with a record/playback device
Inventor: SALTZMAN JEREMY
IPC: G11B27/10
Filed: 1986-05-02
Abstract: To indicate the number of the particular message that has been reached on a bi-directionally movable record medium used with a record/playback device, a position count is incremented and decremented as the record medium moves in forward and reverse directions, respectively; and end-of-message counts representing the locations of the ends of messages relative to an arbitrary reference location of the record medium are stored. Information representing the number of each message whose end-of-message count is stored is provided; and the number of the message which has been reached is determined as a function of which stored end-of-message count is greater than the present position count and which stored end-of-message count is less than that position count. To prevent ambiguities in determining the number of the message which has been reached, as when a new, partially used record medium is loaded into the record/playback device and is reversed to a location which precedes the reference location (i. e. the starting point of the record medium when it is loaded into the device), the position count is preset to a count at least equal to the total length of the medium when the record medium is replaced, to prevent decrementing of the position count below zero, which would be interpreted as being greater than any of the stored end-of-message counts. <IMAGE>

Title: Image differencing using masked CCD
Inventor: RUSHBROOKE DR JOHN GORDON
IPC: H04N3/15
Filed: 1986-12-22
Abstract: A charge coupled device has some of its "pixels" masked by a material which is opaque to the radiation to which the device is to be exposed, each masked region being employed as a storage zone into which the charge pattern from the unmasked pixels can be transferred to enable a subsequent charge pattern to be established on further exposure of the unmasked pixels. The components of the resulting video signal corresponding to the respective charge patterns read-out from the CCD are subtracted to produce a video signal corresponding to the difference between the two images which formed the respective charge patterns. Alternate rows of pixels may be masked, Fig. 5a, or chequer-board pattern masking may be employed, Fig. 5b. In an X-ray imaging system the CCD is coupled to image intensifying and converting means. <IMAGE>

Title: Machine incorporating an accounts verification system
Inventor: JONES JOHN L R
IPC: G07C9/00
Filed: 1989-07-13
Abstract: A value-dispensing machine, such as a postage meter 12, contains a funding register 16 for storing accounting data which has to be communicated periodically to a receiving centre 10; thus, operation of the machine is inhibited after a predetermined period of time or after a predetermined number of operating cycles; at this stage, computer 20 makes use of encryption algorithm 22 to internally generate a code which is dependent on the data in the register 16; the data in the register is sent directly to the receiving centre 10 by means of telephone line 14, or by an automatic connection, or by means of a smart card. The receiving centre uses an encryption algorithm 40 to generate an external code which is relayed back to the machine; if the internal and external codes agree, then the machine is re-activated. This system prevents any attempt by the user to supply false accounting data to the centre. <IMAGE>

Title: Determining physical parameters or properties of metallic samples using inductive techniques
Inventor: STEELE LEONARD MARMADUKE
IPC: G01N27/72
Filed: 1989-11-03
Abstract: In a method and apparatus for determining a physical parameter or property of a metallic sample, such as the carat value of a sample of gold (3), employing an inductive technique and wherein the sample (3) is compared against a reference sample (4) associated apparatus is zeroed, for instance, using a bridge circuit, by inducing a field in at least the metallic sample (3) in accordance with the skin effect. Inductor coils (7), (8) each connected in a respective arm of the bridge circuit are arranged to induce currents in the samples (3), (4). With a high frequency signal energising the coils so that flux does not penetrate the samples to any great extent the air gap between coil (8) and reference sample (4) is mechanically adjusted by raising or lowering supporting spikes (10) to bring the bridge into balance. The coils are then energised with a low frequency signal so that flux extends into the samples and the bridge balanced by a potentiometer in one of the bridge arms. The adjustment of the potentiometer provides an indication of the carat value. <IMAGE>
