Abstract: Mechanism for a muniton device. The mechanism includes a housing (1) containing an arming element (3) and a spindle (9) capable of giving the arming element an axial movement. The spindle (9) is operatively connected to the arming element (3) via a conveyor means (10) which has a thread profile (12), the conveyor means being pivotally journalled in the arming element such that it is able to be turned between a first position (Figures 1 and 2), wherein the thread profile (12) is in engagement with the spindle (9), to a second position (Figures 4 and 7) wherein the thread profile (12) of the conveyor means is disengaged from the spindle. Spring means (4, 13), are arranged, in the armed position of the conveyor means, to return the arming element to said engagement with the movable member.

Abstract: The present invention provides a cooling system with supplemental thermal storage. The cooling system comprises a compressor (12), an evaporative condenser (20), a thermal storage unit (40), and an evaporator (80). During normal outdoor temperatures when building cooling is desired, the compressor (12) output is connected to the evaporative condenser (20) which in turn is connected to the evaporator coil (86). During periods of time when the building is not occupied, the evaporator coil (86) is removed from the cooling circuit and the working fluid passing through coils (46) in the thermal storage unit (40) acts to freeze liquid (50) surrounding the coils (46) within the thermal storage unit tank (52). During unusually warm outdoor temperatures, when additional building cooling is required, the compressor (12) output is connected to the evaporative condenser (20) which in turn is connected to the thermal storage unit (40) which output is in turn connected to the evaporative coil (86). During such operation, additionally chilled working fluid is provided to the evaporator coil (86) due to the working fluid passing through the coils (46) of the thermal storage unit (40) and thereby being further chilled due to the frozen liquid (50) surrounding the coils (46) in the thermal storage unit (40).

Abstract: A programmable gate array with an improved interconnect structure facilitates multi-source networks, communication of signals long distances across the array, and creation of networks in a symmetrical interconnect structure. The interconnect includes direct connections for each configurable logic block in the array to eight neighbors, including adjacent configurable logic blocks and next adjacent configurable logic blocks. Also, the interconnect includes uncommitted long lines which are driven by outputs of configurable logic blocks but not committed through the interconnect to inputs of any specific logic block. Rather, the uncommitted long lines are committed to connections to other segments of the interconnect. The interconnect structure also includes staggered switching matrices at the intersections of the horizontal and vertical buses in the interconnect. Repowering buffers that are configurable in both directions are associated with bidirectional lines in   the interconnect, and include a bypass path. The interconnect provides for communication of control signals from off the chip, from any configurable logic block in the array, and from the input/output structures in the array to any or all other configurable logic blocks and input/output blocks in the array.

Abstract: A driver for a matrix addressable colour display panel (100) in which each column of the display contains pixels of only one colour, and in which red, green and blue pixels of each row are grouped in linear triads. The column circuits for applying control voltage information to the pixels are colour-segregated so that the colour separation of the control voltage information generated by the graphics controller is maintained. The synchronous control voltage information generated by the graphics controller is received triad by triad, making the driver compatible with conventional CRT drivers.

Abstract: A method of equalizing a digitised data signal transmitted as a sequence of data symbols. The received signal is generally distorted by transmission through a dispersive communications channel and the detected symbol  (D)  may differ from the expected symbol  (E).  The received symbols can exist in a plurality of different states depending on the number of symbols in the data alphabet and the extent of intersymbol interference. An estimate of the data symbol is made based on the maximum likelihood of a particular state transition as represented by the so-called branch metric. In the present method a pseudo-Euclidean branch metric (b) is used which is calculated using exclusively additive arithmetic according to the formula 
     b = |d r  - e r | + |d i  - e i | 
     where d r  and d i  are the real and imaginary components respectively of the detected symbol  (D)  and e r  and e i  are the real and imaginary components respectively of the expected symbol  (E).  By avoiding the need for a multiplier the power consumption is reduced. The implementation complexity is also reduced thus minimising the area of semiconductor needed for realization in IC form. A fully multiplier-less equalizer is also disclosed.

Abstract: Load unbalance in an inverter driven washing machine is detected by examining the ripple in the DC inverter bus current. Ripple above a predetermined level is indicative of load unbalance. If the ripple indicates the load is unbalanced, the distribution cycle of the washing machine is attempted again in an attempt to more nearly balance the clothes. After a certain number of tries, if the load is still unbalanced the spin cycle is aborted. If the ripple falls below a predetermined level before the maximum number of tries is reached, the spin cycle is started. The frequency of operation is checked during the spin cycle to adjust the cycle time to the particular degree of load balance achieved.

Abstract: A printed circuit resolver includes a stator assembly (36) comprising a first planar, multi-turn stator winding (50,52) and a second planar multi-turn stator winding (58,60). A rotor assembly (38) is disposed adjacent to the stator assembly and is rotatable with respect to the stator assembly. A voltage is induced in each of the stator windings with each voltage varying according to a trigonometric function of the angular position of the rotor winding with respect to the stator windings. Each resolver winding is planar and comprises at least two planar multi-turn coils formed on a disc. Each coil comprises N turns and 2M sectors. In each sector, the radial and circumferential position of each point of a given turn is defined along radial sector lines radiating from a center point of the disc. The position of each point of a given turn is defined by either an inner turn radius or an outer turn radius. The inner turn radius for any given turn is the distance from the center point of the disc to the most proximate point on that turn as measured along a given sector line. The outer turn radius for that turn is the distance from the center point of the disc to the most distant point on that turn as measured along the same sector line. The sum of all outer turn radii for a given sector line minus the sum of all inner turn radii for the given sector line defines a value; a set of all the values for all sector lines of the coil approximates a sinusoidal function.

Abstract: An exposure method for use in an image forming apparatus for having each of edge emission type electroluminescent (EL) devices emit light a plurality of times to form one pixel of an image.

If the gradient falls between 0° and 45°, the edge emission type EL devices are made to emit light selectively according to the proportion of image-filled regions in the pixels intersected by the outline. If the gradient falls between 45° and 90°, either the light intensity of the edge emission type EL devices is established according to the proportion of image-filled regions in the pixels intersected by the outline, or the number of the pulses which exceed a threshold voltage and which are fed to the edge emission type EL devices is gradually reduced according to reductions of image-filled regions in the pixels intersected by the outline.
