Title: Indexing system
Inventor: WAKEFIELD DEREK JOHN
IPC: G06K21/04
Filed: 1984-05-30
Abstract: In order to select, from a plurality of entries, an entry satisfying certain defined criteria, a set of sheets 1 of the same size each of which is representative of a predetermined criterion for selection is used. Each sheet 1 includes one or more windows 7 located on the sheet in predetermined positions chosen from among a plurality of possible positions 6, each of which corresponds to a respective one of the entries, a window 7 in one of these positions 6 indicating that the corresponding entry satisfies the criterion represented by that sheet 1. The sheets 1 are placed one on top of another and aligned so that corresponding possible positions 6 are in register on successive sheets. The entries, if any, which satisfy the relevant criteria may then be determined by noting the positions 6 in which the windows 7 in successive sheets 1 are in register, and finding the corresponding entries in a reference list. <IMAGE>

Title: Electro-optical mouse
Inventor: MATTHEWS HENRY G
IPC: G06F3/039
Filed: 1985-02-22
Abstract: An electro-optical omni-directional mouse system for controlling the movement of a cursor comprises a mouse 1 movable over a planar surface 3 without regard to the mouse's angular orientation with respect to the pattern on the surface, which includes reflective areas separated by non- reflective portions (eg, areas separated by line segments). A source 7 is rigidly fixed to the mouse housing 5 to emit light that impinges on the surface. Four photodectors 15 are rigidly fixed to the housing to receive the subsequently reflected light and output signals in response thereto as the mouse moves over the planar surface. Amplifiers and comparators transform this output into binary code, from which a microcomputer decodes the binary pattern into distance and direction data, and then processes these data to form position signals for controlling the cursor. The detected surface is optically imaged onto the photodetectors so that the width of a line segment is magnified to correspond to the size of each detector. <IMAGE>

Patent GB-2157132-A (GB)
Title: Indentification systems
Inventor: DENNE PHILLIP RAYMOND MICHAEL
IPC: G01S13/78
Filed: 1985-04-03
Abstract: An identification system comprises an interrogator which transmits an interrogation signal to a plurality of transponders, each of which is arranged automatically to reply by means of a first coded identification signal stored in the transponder and modulated onto a carrier wave transmitted by the transponder. The interrogator receives and checks the reply signal. In the event of there being a plurality of transponders within range and broadcasting reply signals simultaneously, the interrogator receives corrupted reply signals. The interrogator therefore retransmits the reply signals to the transponders and each transponder checks the retransmitted reply signal with its first coded identification signal. In the event of correspondence the transponder discontinues transmission and in the event of non-correspondence the transponder continues transmission. In a polling mode of operation, the interrogator initially transmits a second coded identification signal corresponding to a selected transponder, and each transponder within the range compares the second signal with the first signal stored therein. If correspondence is established, the transponder is adjusted to receive further instructions which may comprise replacement of data stored therein. Each transponder includes a demodulator (34) comprising a phase locked loop which provides data, clock and carrier detect signals to a CPU (50) which includes ROM, RAM and an ALU. The carrier detect signal enables the CPU to switch the transponder from a power down condition to a power up conditon.

Title: Apparatus for playing a game
Inventor: GOODWIN JEFFREY
IPC: A63F3/02
Filed: 1985-09-19
Abstract: An apparatus for playing a game comprises e.g. four boards and sixty cards. The boards are divided into nine regions arranged in 3-region rows and columns. The cards comprise five subsets of twelve cards each. The twelve cards of each subset have a common numeric indicium thereon and three pictorial animal representations are distributed equally over the subset (i.e. the subset has four of each representation). The numeric indicium of each subset differs from that which characterizes each of the others so that the set as a whole features five different numeric indicia of which there are twelve represented on cards. Each of four players is dealt five cards. Playing the cards to the boards is practiced by each player with respect to his board according to game rules with the object of filling as many of the eight rows and columns (including two diagonals) with three cards whose numeric indicia have a sum (the line target) (which is nine in Fig. 10) equal to the sum applying to another row or column so filled. The sum of the card indicia in all such equal rows and columns has subtracted from it the sum of the card indicia in 2-card rows, and 3-card rows which do not equal the line target, to give a final score for each player for that game. Game end is signified by the call of a player who has exhausted his cards or when a replenishment pile of cards initially constituted by the balance of the 60-card set not dealt out to the players is exhausted by such cards being taken into the hands of players according to game rules to replenish cards played to board. <IMAGE>

Patent GB-2208740-A (GB)
Title: Liquid crystal devices
Inventor: BOWRY CAROLYN
IPC: G09G3/36
Filed: 1987-08-12
Abstract: In a method of driving a matrix of ferroelectric liquid crystal devices in a TDM mode, each strobing signal (20) comprises first and second pulses (21, 22) of opposite polarities and of different amplitudes, together with a dc voltage (23) which is applied from the end of the second pulse to the beginning of the first pulse of the next strobing signal on the same strobe line to cancel the dc level which would be caused by the unequal pulses. The strobe lines are addressed in sequence, and the timing of the strobing signals is such that the strobing signal applied to any strobe line (24) partially overlaps the strobing signal (20) applied to the immediately preceding strobe line in the sequence, thereby reducing the effective time required for addressing each strobe line to less than two strobe pulse time slots per frame, as compared with the conventional four time slot systems.

Title: Ring oscillator
Inventor: COWLEY NICHOLAS PAUL
IPC: H03B5/24
Filed: 1988-05-05
Abstract: The invention provides an oscillator which requires no external resonance components. The oscillator is formed as a unity gain loop incorporating 180 DEG  phase shift and delay means. The frequency of oscillation is proportional to the delay. The current dependent delay of each gain stage is used as a variable delay means, delay and hence frequency of oscillation being varied by varying the supply current, thereby varying the nominal 180 DEG  phase shift of each stage such that the total loop phase shift is 360 DEG  at the frequency of oscillation. A modified arrangement uses only a differential inverting amplifier and a unity gain differential buffer connected in a loop. <IMAGE>
