Abstract: A startup circuit has an undervoltage monitoring unit and a pulse width modulator PBM with at least one soft start input and one enable input. When switching on the power pack, the undervoltage monitoring unit is disabled until the voltage level at the output has reached a rated value. Outputs of two comparators are connected to the enable input of the pulse width modulator over a NAND gate. A capacitor chargeable via a resistor is applied to the first input of the first comparator with a controllable electronic switch connected in parallel to the capacitor. A first reference voltage is applied to the second input of the first comparator and a second reference voltage equal to or lower than the first reference voltage is connected to the first input of the second comparator. The output voltage of the power pack is connected to the second input thereof. The voltage generated at the capacitor is connected to the soft start input of the pulse width modulator over a biased rectifier whose bias voltage is equal to or lower than the first reference voltage. A control circuit comprising an input for switch-on instructions and an input for switch-off instructions is connected at its output to the control input of the electronic switch. The enable input of the pulse width modulator is also connected to receive the switch-off instruction.

Abstract: The present system includes, in a preferred embodiment, a plurality of bit map memory units which together define a large bit map memory. For each bit map memory unit there is also included a mask means and four extended shift registers. The shift registers can be loaded in parallel with pixel information through bidirectional data transmission channels which include bidirectional mask means. The pixel information can be routed through said bidirectional mask means to different address locations, or to the same address location, with certain of the pixel bits removed by the mask means. The shift registers have both serial and parallel input and output mans and are clocked at different speeds to accommodate different peripherals. At least a first shift register is designed to be serially read out at a relatively high rate which can be advantageously used by a video display device or the like. Information signals from the other shift registers are transferred at high speed (in parallel) into and out of the large bit map memory to said first shift register whereby pixel information signals are settled down before being routed from said first shift register. The bidirectional mask means and the bidirectional data transmission channels along with the multiplicity of shift registers permit the present system to handle many varied operations which operate at different speeds.
