Title: Electronic control for an automatic washing machine with a reversing psc motor
Inventor: BASHARK LARRY T
IPC: D06F34/08
Filed: 1990-08-09
Granted: 1995-01-17
Abstract: A control for an automatic washing machine with a reversing permanent split capacitor (PSC) drive motor.          Separate ferrite core sensors surround each of two PSC motor windings.  A sense winding is threaded through both sensors.          A brief output voltage is generated whenever the alternating current in either PSC motor winding passes through a zero-crossing and when the sense winding is wound with proper mutual polarity, an output voltage is generated in response to zero-crossings of a brief, residual alternating current which flows in both PSC motor windings and the capacitor when the rotating PSC motor is cycled OFF.  The circuitry, in combination with the sensors, samples the leading or lagging phase angle of the PSC motor auxiliary or main winding, respectively, at a sample rate of two-times the line frequency when the PSC motor is ON; and further monitors the PSC motor braking phenomena by counting the residual current alternations when the PSC motor is cycled OFF following the powered portion of each CW or CCW agitator stroke.  The raw PSC motor phase data is used in microcomputer programs to compute motor start time or load torque dither.  This computed information and the PSC motor braking data, is used by other software programs to automati-cally control various functions of the washing machine such as the fill water level and agitator stroke angle; to control events in an operational sequence such as the duration of the agitation and spin operations; and to provide diagnostic infor-mation such as spin off-balance detection.

Title: Device to determine and/or monitor a predetermined filling level in a container
Inventor: PFANDLER MARTIN
IPC: G01F23/22
Filed: 1992-06-05
Granted: 1997-02-25
Abstract: The device has at least two vibration rods secured at a distance apart to a diaphragm, the edge of which is connected to a screw-in member. A clamping screw is secured to the diaphragm on the side away from the clamping rods tightly enough for the clamping screw and the diaphragm to adopt a position in which the axes of symmetry coincide. The clamping screw is sur-rounded by a stack of annular piezoelectric elements, electrodes and insulating rings, The stack forms the excitation and recep-tion converter of the device. The stacked excitation and reception converter is clamped and secured between the diaphragm and a hexagon nut. The stack is supported by means of the terminating metal ring on a shoulder surrounding the diaphragm and posi-tioned at a distance from it. The clamping force is selected so that the diaphragm is prestressed to a concave shape at the same time. The excitation converter excites the vibration rods to vibrate at their natural resonant frequency transversely to their longit-udinal axes. The reception converter detects a change in the vibration behaviour of the vibration rods and use is made of this to determine and/or monitor the predetermined level. The change in both the vibration frequency and vibration amplitude of the vi-bration rods may be taken into account.

Abstract: An optical communications system (10) comprises a transmitter (12) and a receiver (14). A source (16) of correlated pairs of photons of conjugate energies provides first and second photon beams (38, 36). The first photon beam (38) passes through a modulated filter (50) to which a communications signal (52) is applied. A  variable spectrum beam (54) is produced which is con-verted to a timing signal (68) of macroscopic optical pulses (66). The second photon beam (36) and timing signal (68) are trans-mitted to the receiver (14). The received timing signal (84) is converted to a series of electrical timing pulses (90). The received sec-ond photon beam (82) passes through an unmodulated filter (94) matched to the modulated filter (50) when the signal (52) is not applied. The unmodulated filter splits the beam (82) into two conjugate spectra photon beams (96, 98) which are then converted to first and second series of electrical pulses (108, 110) respectively. The pulses (90, 108, 110) enter a coincidence counter (92) which records coincidences between the timing pulses (90) and the first series of pulses (108) and between the timing pulses (90) and the second series of pulses (110). Two coincidence rates are obtained and subtraction of one from the other yields an output communications signal (112).
