Abstract: A matrix display system comprises an active matrix display device (10), for example a liquid crystal device, having a column and row array of picture elements (12) defined by opposing electrodes (16,17) with associated switching elements (11), such as thin film transistors, which are selectively operable by switching signals supplied via row conductors (14) to apply data signals supplied via column conductors (15) to the picture elements. The picture elements (12) are arranged in groups of at least two with the picture elements of each group being addressed via one row conductor (14) and one column conductor (15) and their associated switching elements (11) being operable at respective different levels of the switching signal for selective control. In this way, the number of address conductors (14,15) required can be reduced, allowing for example higher picture element densities. 
     The picture elements of each group may be from the same row or adjacent rows. For a full colour display, each group may comprise three picture elements each displaying a respective primary colour.

Abstract: A standard pseudo-random number generator comprises a shift register with a plurality of XOR feedback paths from the last stage to the first and selected intermediate stages. This invention provides a larger generator by concatenating four such registers 9a to 9d in series. The feedback pattern of each register is a maximum length polynomial, and the registers are all of different lengths (67, 63, 64, and 65 bits) such that their periods are all coprime. The largest register is first for maximum randomness. 
     The number of feedback paths of each register is an even integer approximately equal to either one third or two thirds of the number of stages in the register. 
     The generator may be used in a VLSI chip including a core logic area performing an operational function to apply a test pattern to the core logic. For receiving the output of the core logic in response to the test patterns, the chip may include an check sum output register 8 in the form of a cyclic ring with an initial, relatively small portion in the form of a linear feedback shift register. The generator and check sum output may form part of test circuitry in a VLSI chip. being configured partly from I 0 cells and partly from dummy cells, the 1/0 cells normally operating as input and output to the core logic of the chip.

Abstract: A safety device for an internal combustion engine powered implement and for disabling the operation of the internal combustion engine by means of a brake. The safety device includes a braking lever (40) and a control lever (60) which are both mounted on a single pivot member (38). Two springs (46,66) are provided, the first of which normally urges the braking lever into contact with the flywheel (30) of the internal combustion engine to prevent rotation thereof. The second spring biases the control lever into a rest position wherein the deadman control lever assumes its normal non-operated position and allows adjustment of control effort. The braking lever and control lever are mounted on the pivoting member by means of bushings to permit independent pivoting movement of the levers when the deadman lever is operated. The control lever contacts the braking lever by means of an abutment surface (92) thereby rotating the braking lever out of contact with the flywheel and permitting the engine to operate. The braking lever also includes a protrusion for contacting an ignition circuit switch (78) whereby the ignition circuit of the engine is also disabled in the rest position of the deadman control lever.

Abstract: A memory matrix (102) for storing control words for controlling a common control time division multiplexed (TDM) switch (101) is formed by employing a plurality of shift registers (201-1 through 201-M) connected in recirculating configuration. Synchronization of control word time slots in the memory matrix to system timing is realized by storing a timing marker (in 210) which is advanced (via SCK) in identical manner as the control word time slots. If synchronization between the system timing and control word time slots is interrupted, it is restored by controllably inhibiting (via 204, 206, 207, 208, 209) advancing of the control word time slots and the stored timing marker.

Abstract: A web transfer mechanism in a paper roll towel dispenser of the type having a primary roll (12) and a reserve roll (14) of paper toweling comprises a cradle (16) for suppor­ting the primary roll (12) that is counterbalanced by an element (32) for tucking the leading end of the reserve roll (14) into the nip between feed rollers (24,26). As the primary roll (12) becomes depleted, the counterbalancing force of the roll decreases, causing the tucking element (32) to gradual­ly approach the leading end of the reserve roll (14) until the element (32) finally engages the end and introduces it into the nip.
