Abstract: An N-channel power MOSFET (M2) is fabricated with its source and body connected together and biased at a positive voltage with respect to its drain. The gate is controlled by a switch (1184) which alternatively connects the gate to the source or to a voltage (VCP) which turns the channel of the MOSFET fully on. When the gate is connected to the source, the device functions as a 'pseudo-Schottky' diode which turns on at a lower voltage and provides a lower-resistance path than a conventional PN diode. When the gate is connected to the positive voltage the channel of the MOSFET is turned fully on. This MOSFET switch is particularly suitable as a synchronous rectifier in a power converter where it reduces the power loss and stored charge in the 'break before make' interval.

Abstract: An alternator system according to the present
invention can decrease rapidly G-surge voltage appearing when
a B-terminal as an output terminal is disconnected. On a rotor
20 constituting a magnetic field, permanent magnets 28 as a
second magnetic flux source are disposed in addition to a field
coil 24 as a first magnetic flux source. The permanent magnets
28 supply magnetic flux in a direction opposite to magnetic
flux supplied by the field coil 24, and an amount of magnetic
flux supplied by the permanent magnets 28 is substantially
equal to an amount of magnetic flux supplied by the field coil
24. Accordingly, a cross-sectional area of the magnetic
circuit in the rotor can be made smaller, and an inductance of
the field coil 24 can be made lower. The G-surge voltage can
be decreased rapidly because magnetic flux linking with the
field coil 24 is rapidly attenuated by the magnetic flux from
the permanent magnets 28.

Abstract: A digital motion video processing circuit can capture, playback and manipulate digital motion video information using the system memory of a computer as a data buffer for holding compressed video data from the circuit. The system memory may be accessed by the circuit over a standard bus. A controller in the circuit directs data flow between an input/output port which transfer a stream of pixel data and to the standard bus. The controller directs data to and from either the standard bus or the input/output port through processing circuitry for compression, decompression, scaling and buffering. The standard bus may be a peripheral component interconnect (PCI) bus. The motion video processing circuit has a data path including pixel data and timing data indicative of a size of an image defined by the pixel data. The timing data is used and/or generated by each component which processes the pixel data, thereby enabling each component to process the pixel data without prior knowledge of the image format. By having processors for handling two compression formats for motion video data connected to this data path, conversion between compression formats, such as between MPEG to Motion JPEG, can be performed.

Abstract: A method for preparing power factor control integrated circuits which generate linear pulse width modulation (PWM) waveforms is presented. The method of pulse width modulation waveform generation involves providing a capacitor; fast charging the capacitor; and controlling a discharge rate of the capacitor to ensure a constant switching period and a linear PWM waveform. The method is applicable for any single-phase ac/dc converter topology that performs power factor correction. Unlike conventional techniques which utilize three feedback loops, the method of the present invention reduces the total number of feedback loops to two, eliminates input voltage sensing and achieves the same objective. This method results in significant integrated circuit simplification, such as elimination of multiplier, squarer and divider circuits in the control integrated circuit and reduces the cost of the integrated circuit.

Abstract: The method involves assigning cyclically continuous sequence numbers to message cells of a virtual connection, and copying a message cell to a group of redundant message cells, whose amount equals the amount of redundant transmission paths. The message cells are transmitted over the redundant transmission paths, and only one message cell which follows the currently processed message cell according to the sequence number carried by the message cell, is selected for further processing. The sequence number of the last transferred message cell is stored for each transmission path, and compared to the sequence number of an arriving message cell. A decision is made whether the arrived message cell is assumed for further processing according to the comparison result. A counter is provided for each transmission path, whereby the counter is increased by a first value in case of an acceptance of the arrived message cell of the concerned transmission path. The counter of the concerned transmission path is reduced by a second value if the sequence number of the arrived message cell does not match. A transmission path whose count reaches a lower threshold level is exempt from receiving message cells for further processing.
