摘要： A system for sensing loads in a washing machine by measuring angular acceleration is provided. The washing machine includes a washer basket and an agitator that can be angularly accelerated about a spin axis during a predetermined dry spin cycle. The system includes a magnetic source, such as a permanent magnet, positioned in the agitator for producing a predetermined magnetic field. A magnetic sensor, made-up of inductive coils or solid state sensors, is positioned to be electromagnetically coupled to the magnetic source for supplying an output signal that varies in a predetermined manner as the agitator is angularly accelerated relative to the magnetic sensor. A signal processor is coupled to the magnetic sensor for receiving the output signal supplied by the magnetic sensor. The processor is designed and/or programmed for measuring loads in the washer basket based on the output signal received from the magnetic sensor while the agitator is angularly accelerated relative to the magnetic sensor upon initiating the dry spin cycle.

摘要： A Mach number sensor comprises a first pulse speed sensor situated in direct contact with an open area through which a first pressure pulse can pass and a second pulse speed sensor situated in a thermally conductive tube with membrane-covered ends having stationary air through which a second pressure pulse can pass. Each of the first and second pulse speed sensors may comprise two total internal reflection detectors and a timer for determining elapsed time for passage of the pressure pulse between the two detectors. Each of the total internal reflection detectors can be selected from the group consisting of a single optical fiber having cladding removed at a surface facing the area through which the pressure pulse can pass; and a prism having a first surface facing the area through which the pressure pulse can pass, an input optical fiber optically coupled to a second surface of the prism for supplying light to the prism through the second surface, and an output optical fiber optically coupled to a third surface of the prism for detecting light emerging from the prism through the third surface.

摘要： An alternating current sensor employing a mutually-inductive current sensing scheme comprises a conductive pipe and a cylindrical-shaped conductive element at least partially surrounded by the pipe. The pipe is substantially concentric to the conductive element and a conductor electrically connects a pair of corresponding ends of the pipe and conductive element to form a connected conductive path through the sensor. The pipe and the conductive element are spaced apart a predetermined radial distance to form a magnetic field in the space between the pipe and conductive element during current flow along the conductive path.
