Title: Improvements Relating to Timing Circuits
IPC: H03K17/28
Filed: 1980-08-21
Abstract: A circuit arrangement for timing a delay between functions, such as the time delay between the launching of a chaff-dispensing projectile and the dispensing of chaff by said projectile comprises tuned circuit means responsive to an electrical signal for predetermined frequency which has a duration for determining said delay between functions and further comprises means conditioned in dependence upon the duration of said signal and means effective when the first of said functions is performed to cause the conditioned means to respond for the timing of said delay. In the analogue system shown, a first frequency AC signal charges 8 via rectifier 7 to provide d.c. power. A different frequency to which 9, 10 are tuned, operates switch 11, thereby charging 13 at current I, for time T1. Subsequently switch 18 is closed to discharge 13 at current I2, the delay time being the time taken for Vc to fall to reference voltage VR, when 22 is energised by switch 21. Timing functions may alternatively be provided digitally. <IMAGE>

Patent GB-2074457-A (GB)
Title: Respiratory mask system
IPC: A62B18/02
Filed: 1981-04-01
Abstract: A respiratory mask system has a main mask 1 and an inner half mask 5. A non-return valve 9 permits respiratory gas to flow only from the half mask 5 to a space 10. Thus, during exhalation, the space 10 is charged to a super-atmospheric pressure and this pressure prevents infiltration of the surrounding atmosphere into the main mask 1. As there is no permanent open connection between a respiratory gas circuit and the space, large losses of respiratory gas due to leaks should not occur. <IMAGE>

Title: Personnel identification device
Inventor: CHEUNG WILLIAM SHIU HUNG
IPC: G07F7/10
Filed: 1981-06-22
Abstract: A personnel identification device (Figure 1) carried by a user provides two codes for checking apparatus. A ROM 14 provides a check-in pass code which is transmitted by transmitter 19 to the checking apparatus which transmits back to a receiver 21 an interrogation code which is compared at 22 with a standard check code from ROM 23. On satisfactory comparison, a personnel identification code can be transmitted. This is keyed in at 13 by the user at each use of the apparatus, noted in a memory 15 and transmitted from 19 to the checking apparatus, which will allow the user to pass or raise an alarm as appropriate. The apparatus can also be used for checking out, a check-out pass code being stored in a ROM 31 and transmitted from 19 together with the personnel identity code stored at 15. After a time delay at 34, the personal identity code is erased from the memory 15. <IMAGE>
Patent GB-2102533-A (GB)
Title: Buffer assemblies
Inventor: CRESSWELL RICHARD
IPC: H01Q3/06
Filed: 1981-07-16
Abstract: It may often be the case that the allowable range of angular movement of an object, such as a steerable microwave aerial, mounted for rotation about an axis needs to be finite, the end-of- range positions being defined, and mechanically constructed, using end stops (buffer units) which are fixedly secured to one of either the rotating object or its mounting and which interact with a stop abutment member (striker plate) fixedly secured to the other, and yet greater than 360 DEG . The invention seeks to allow such a range to an aerial (or other rotating object) by arranging for the interaction between buffer unit 21 and striker plate 24 to be via a buffer plate 23 slideably mounted upon an arcuate guide rail 22 extending between two buffer units; the striker plate engages not the buffer units but the buffer plate, which slides up to and engages the relevant buffer unit, so extending the movement range by the angle subtended by the two buffer units. The buffer units may contain friction ring-springs, or may be simple physical stops. As shown an aerial attached to framework 12 may be rotated through more than 360 DEG  in an anti-clockwise direction before being stopped by the entrained buffer plate 23 engaging the right-hand buffer unit. <IMAGE>

Title: Code recognition circuit
Inventor: JEFFREY COLIN
IPC: G06F7/02
Filed: 1981-07-27
Abstract: An incoming N bit digital data word is loaded into a recirculating shift register (10 and 11) which is clocked at a high clock rate that is a multiple of the incoming data word bit rate. The recirculated word and a predefined word are compared serially at the high clock rate in a compare element (12), the differences being counted (13). The circuit is particularly suitable for large scale integration, since it employs less logic elements than conventional parallel compare methods, and suitable for applications requiring high comparison speeds, such as in digital radio pager receivers. The application of the circuit to a pager decoder custom integrated circuit is discussed. <IMAGE>

Patent GB-2109970-A (GB)
Title: Signature recognition
Inventor: BREWSTER ARTHUR EDWARD
IPC: G06V10/12
Filed: 1981-11-10
Abstract: A written signature is validated electronically as in connection with a bank transaction terminal, by comparing predetermined parameters of a waveform derived from pen movements, such as a pen velocity waveform, with upper and lower limit reference levels previously derived from sample signatures and held in a store. For at least one parameter, such as the crossing of a particular threshold voltage value as detected by a threshold detector 2, the waveform is divided into a plurality of successive time segments by gates G1-G6 successively enabled by logic 5 and the parameter as detected by respective counts C1-C6, in each time segment is compared with respective upper and lower limit reference levels. The time segments may be equal in length and of a fixed duration, unequal in length following a selected distribution, for example logarithmic, or equal in length and of a duration determined by the expected overall signature duration. The time division permits different signatures with the same total number of threshold voltage transitions, for example, to be distinguished. <IMAGE>
