Patent EP-0312260-A2 (EP)
Inventor: SWARTZ ROBERT GERALD
IPC: H04L7/033
Filed: 1988-10-07
Abstract: A demultiplexer for demultiplexing a multiplexed input data signal into M output channels using M sequencer means clocked from an overlapping M phase system clock. The system clock operates at a frequency equal to the input data signal rate divided by M. Each sequencer means is clocked by a unique combination of the M phase system clock signals to select one data channel from the multiplexed input data signal. Since all sequencer means circuits are synchronized to the system clock, no variable delay lines are needed to align the timing between the circuit stages. A time delay latch is provided where needed in each sequencer means to enable all channels to output data concurrently. The demultiplexer includes a real-time data-framing capability to assure that the input data is correctly mapped to the proper output channels.

Abstract: The present invention relates to a method and to apparatus for grading objects according to size, for instance potatoes. The objects are advanced along a broad, flat and divided conveyer path (1,2). Image data relating to the size of respective objects is obtained with the aid of a camera (3) and a light source (4). At the correct moment in time, control codes are transmitted to one, two, three or four finger groups (5,6,7,8) which function to guide the objects in mutu­ally different directions, in accordance with the respe­ctive sizes of the objects. The invention enables the objects to be sorted gently and effectively from the transport path (1,2), into as many as five mutually different, individually selective sizes.

Abstract: A field emission scanning electron microscope in which an aperture plate (4) is disposed in a high-vacuum region between an accelerating electrode (3) and a condenser lens (5). Since a probe current can not be controlled by a lens system with the abovementioned structure, the probe current is controlled by controlling an extracting voltage applied to an extracting electrode (2). Deviation of the focal point taking place in accompanying a change of a virtual electron source position as brought about by the control of the probe current is corrected by controlling the focal length of a condenser lens (5) such that the electron beam has a constant spread on the principal plane of an objective lens (8) to thereby maintain a beam aperture angle (α i ) at a specimen (9) to be constant.

Abstract: In modern data communications systems, it is frequently necessary to detect predetermined bit patterns or character patterns in a data stream. A method is proposed for this in which the bit sequence to be found is stored as bit pattern in a memory. In the memory, further bit patterns are stored which are read out of the memory as a function of the characters occurring in the datastream and are supplied in parallel to a shift register. In the shift register, an identification is continuously forwarded from the first stage to subsequent stages as long as a correspondence of the bit sequence examined with the bit pattern sought is given. The last stage of the shift register then identifies the correspondence with the bit pattern sought.
