Title: Power factor correction circuit
Inventor: COUNTS RICHARD C
IPC: H02M1/00
Filed: 1991-01-23
Abstract: Abstract In a ballast circuit for producing a DC signal with a high voltage amplitude, a capacitor is connected to a circuit output.  The capacitor stores a charge which provides the high voltage amplitude of the DC signal. current from an inductor is used to charge the capacitor.  A current gate, when it is turned on, drains current from the inductor.  A control circuit turns the current gate on and off so that the amplitude of the current drawn from the incoming AC voltage signal is in phase with the amplitude of the voltage of the incoming AC voltage signal.  The control circuit includes a ramp generator which generates a pulse modulation reference signal with a varying voltage amplitude and a comparator which compares the pulse modulation reference signal with the incoming AC voltage signal after the incoming AC voltage signal has been rectified and the voltage divided by a voltage divider.  The comparator produces a first modulated signal.  The control circuit also includes a second comparator which compares the pulse modulation reference signal with a feedback signal to produce a second modulated signal.  A logical AND is performed on the first modulated and the second modulated signal to produce a control signal.

Filed: 1991-02-07
Abstract: In a multi-station radio communications system wherein plural channels are accessible for communication between plural fixed stations and plural mobile units (viz., dynamic channel assignment) and wherein each of plural fixed stations selects a channel according to channel assignment priority data, the radio channels are grouped into a plurality of channel groups.  The channels in each of the channel groups forms a numerically looped sequence of channels.  The first channel of the numerically loop sequence in one channel group is different from the first channel of the numerically looped sequence in each of the other channel groups. Each of the plural fixed stations is set to select the channel having the highest priority or to select one of the first channel of the numerically looped sequence and a channel nearest to the first channel in the event that a plurality of channels have the same priority.

Abstract: FIELD SHIFT MOIRE SYSTEM                           ABSTRACT    An apparatus and method for providing high resolution non-contact absolute contour measurements of an object with moire interferometry.  The invention utilizes a projection moire system in which the entire projection system is translated to perform a field shift.  The field shift produces a phase shift that is proportional  to the height of the object.   A coarse three dimensional map of the surface is first obtained from the phase shift.    This  is  combined  with  high  resolution  relative measurements of the phase to obtain an absolute Z map of the surface.  The invention does not suffer from the 2.pi.   ambiguity problem and is suitable for prismatic discontinous structures.          In addition, the present invention is applicable to industrial environments  and  requires a  relatively  inexpensive  optical system.  Further, the field shifting technique is applicable to fast  parallel  process  computers  thereby  allowing  for fast absolute contour generation of prismatic parts.
