Abstract: An optical switching system, wherein the input channels (I) carrying packetized data are switched one by one at high bit rate to output channels (O) through an optical switching network (RC). 
     The packets of a generic input channel are time compres­sed, converted into optical signals and, at suitable instants, sent to an optical switching network to be switched to the desired output channel, they are then reconverted into electrical signals and ex­panded to their original duration. 
     A centralized processor (EL) controls the channel switching through the switching network by means of a driving circuit (LC).

Abstract: An image reading apparatus, for converting an image on a document having a white/black text area into a display signal (S4), includes an image reader that scans pixels forming the image to produce a read signal (S1/S22) having a level corresponding to the brightness density of each of the scanned pixels. The read signal (S22) is compared (26) with a dither matrix data signal (S23) and converted into a dither converted signal (S24/S11). The read signal (S1) is also compared (41) with a threshold value and converted into a binary signal (S31/S12) having a first level representing a white pixel and a second level representing a black pixel. A discrimination circuit (42) receives the binary signal for producing a detection signal (S40) when the white/black text area is scanned. Upon occurrence of the detection signal (S40), the dither converted signal (S11) is mixed with the binary signal (S12) to form the display signal (S4).

The projection (4) has a height which is greater than 50% of the thickness of the lamination and the depression (3) has a depth which is greater than 50% of the thickness of the lamination. The depression (3) and projection (4) are produced by a projection punch (13) which cooperates with a die (14). The die has a lip which is either radiussed (r) or conical (C) and the punch (13) causes the metal of the lamination to be extruded past the lip into the die (14) whilst the depression (3) is being formed. The radiussed or conical lip allows the height of the projection and the depth of the depression to be greater than the normal 50% shear stress fracture depth/height.

Abstract: An arrangement for detecting movement in a picture displayed on a television display. Y/C color separation detects movement in a displayed picture by generating a first movement detection signal with respect to luminance, a second movement detection signal with respect to luminance and a movement detection signal with respect to color. The first movement detection signal with respect to luminance represents the difference between a luminance signal extracted by Y/C separation in a first frame and a luminance signal extracted by Y/C separation in a second, adjacent frame. The second movement detection signal serves as an auxiliary detection signal, and indicates any leaking of the color signal into the luminance signal after Y/C separation. The auxiliary signal, which indicates the leakage of any color signal into the luminance signal, is able to minimize erroneous detection of movement due to leakage of the color signal.

Abstract: A circuit arrangement for applying a current pulse to a load 9, such as a magnetron or klystron, includes a main switch 14 and an auxiliary switch 15. Prior to transmission of the pulse, charging current is applied via an inductor 10 to a pulse forming network 12. Once charging is complete, the main switch 14 is triggered and the pulse is applied to the load 9 via a pulse transformer 13. After transmission of the pulse, energy is transferred from the core of the transformer 13 to the pulse forming network 12. When maximum energy transfer has almost occurred, the auxiliary switch 15 is triggered, causing an inverse voltage to be applied across the main switch 14. This ensures that the main switch 14 can undergo recovery, even under adverse operating conditions.

Abstract: A vector data processing apparatus having a set of vector registers (652), one or more memory access pipelines (650, 651), and one or more composite calculation pipelines (653-660), wherein the vector registers (652) consist of a plurality of banks, and each bank is independently accessible. Each of the pipelines (650, 651, 653-660) can cyclically access each of the banks of the vector registers (652) when one or more of a predetermined number of time slots, through each of which time slot said access is carried out, are assigned to an instruction using the pipeline. Immediately when a memory access instruction is received, a vector unit control circuit (66), which controls operations of the vector data processing apparatus, assigns a time slot for the newly-detected memory access instruction using a memory access pipeline, if it is determined that the memory access pipeline is available based on the pipeline operation status flags (2), and that a time slot is available based on the detected status of the predetermined number of time slots. Further, when a composite calculation instruction is received, the vector unit control circuit (66) assigns one or more time slots, to a newly-detected composite calculation instruction using a composite calculation pipeline, if it is determined that the composite calculation pipeline is available based on the pipeline operation status flags (2), and that time slots are available based on the detected status of the predetermined number of time slots.

Edge points are then determined between pairs of curvature extrema. Edge points found between curvature extrema (20) are then correlated with other edge points in previous scan lines to determine if they fall within a range of predicted line segments. Line segment data may then be processed at higher levels to identify objects in the data.
