Patent EP-0266873-A2 (EP)
Inventor: ILLMAN RICHARD JOHN
IPC: G01R31/3185
Filed: 1987-09-09
Abstract: A programmable logic array (PLA) is described, having an integral decoder (14) for selecting individual product lines (P1-P7). The integral decoder receives an input address by way of a set of buffers (c), which can be disabled so as to disable the integral decoder in normal operation. The buffers can be tested in their disabled state by means of an extra product line and extra output line (27). The extra product line (26) is coupled to all the bit lines and to the extra output line, but not to any of the other output lines; the extra output line is coupled to the extra product line, but not to any of the other product lines. The buffers are tested by applying a sequence of addresses to the buffers in their disabled state, and observing the extra output line.

Abstract: IMPROVEMENTS IN AND RELATING TO THE PROCESSING OF VIDEO IMAGE SIGNALS 
     
     A storage and interpolation device for digital tele­vision pictures comprises a memory organised in 'tiles' of memory elements (2). Sub-assemblies of tiles (2A,2B, 2C,2D) all have the same coordinate address in one coordi­nate direction and have outputs coupled to an interpolation filter (6) operative in that direction. Individual tiles (2A;2B;2C;2D) of respective sub-assemblies (1A,1B,1C,1D) all have the same coordinate address in the other coordinate direction and the outputs of the filters (6) of the sub-­assemblies are connected to inputs of a further filter (9) operative in the other coordinate direction. By allo­cating pixel values of discrete image areas of the picture to respective sub-assemblies (1A,1B1C,1D) in the horizontal direction and to groups of tiles (2A,2B,2C,2D) in the vertical direction, interpolation can be effected by addressing all tiles simultaneously to produce a correspond­ing output from the filter 9.

Abstract: A digital robot control employs planning and trajectory programs which generate the trajectory plan and trajectory position commands with the use of an acceleration profile and a deceleration profile selected from at least squarewave and sine wave profiles. In one embodiment, the planning program generates a time profile including acceleration, slew and deceleration time segments and the trajectory program generates position commands in accordance with the time profile applicable to the current move segment. In an alternate embodiment the planning program generates a motion profile for implementing each robot program motion command in accordance with specified time for acceleration, slew and deceleration. The trajectory program generates position commands along the present path segment either in accordance with a predefined type of path move or in accordance with a curved path trajectory and in accordance with a time profile applicable to the present path segment.

Abstract: A method of determining gum content and performing quality control in the production of a gasoline to minimize the gum content in the produced gasoline. A representative sample of the gasoline is subjected to UV spectrophotometric analysis and the peak heights representing absorption in the range of 310 to 600nm are integrated to determine a total absorption quantity which relates to the actual and potential quantity of gum in the gasoline. This quality control technique will result in a refiner having more control over gum content at a hydrocarbon processing unit, such as a catalytic reformer.

Abstract: A microprocessor is employed to control a test programme which operates to cause a component under test to be filled (or evacuated) to a predetermined pressure p 2  at which a leak test is to be carried out. The test programme is arranged firstly to perform a rapid test at atmospheric pressure p, to determine the pressure change      in the component due to the temperature fluctuation. The component is then filled (or evacuated) automatically to the test pressure p 2 , at which the leak check is carried out. Temperature compensation is achieved by subtracting the value of C      from the pressure change      actually measured, i.e. the actual leak rate      is given byd     where the constant, C, is generated from an identical programme run, the calibration run, on a known non-leaker with a high temperature fluctuation.

The memory cells each consist of non-volatile transistors provided with a control gate electrode, a floating gate electrode and an erase gate electrode. Bit lines (12) to which one end of each of the series circuit units of the plurality of series circuit units arranged in one row are connected in common. Column lines (14) are provided in common for the series circuit units that are arranged in one column and that are respectively connected to each control gate electrode of the memory cells constituting each of the series circuit unit. A voltage by which the selected non-volatile transistor works in a saturation state is applied to the control gate electrode of the selected transistor of a series circuit unit by a column line, thereby injecting hot electrons from the semiconductor substrate into the floating gate electrodie. Another voltage by which the non-selected non-volatile transistor works in a non-saturation operation is applied to the gate electrodes of the remaining non-volatile transistors of the series circuit unit. By sequentially selecting memory cells in one series circuit unit, the sequential data writing operation is performed. The sequential data reading operation is performed in a similar manner.
