Abstract: The present subject matter relates to methods and apparatus for controlling operation of a washing machine motor. Different control algorithms may be used during different time periods of operation of the motor where each algorithm is configured to provide different operating characteristics of the motor based on the needs of the washing machine system. The method and apparatus both provide for changing from one motor control algorithm to another algorithm while the motor is spinning. For certain type motors, a time period may be established between operation of the motor under a first or second control algorithms where no energy is supplied to the motor but the motor is permitted to continue to spin. During this period of time for these type motors, magnetic fields in the motor are permitted to subside prior to application of the second control algorithm.

Abstract: A flexible, fabric-based circuit comprises a non-conductive flexible layer of fabric and a conductive flexible layer of fabric adjacent thereto. A non-conductive thread, an adhesive, and/or other means may be used for attaching the conductive layer to the non-conductive layer.

In some other embodiments, an automated milling machine or a computer-driven laser using a pre-designed circuit trace as a template cuts the conductive layer so as to separate an undesired portion of the conductive layer from a desired portion of the conductive layer. Additional layers of conductive fabric may be attached in some embodiments to form a multi-layer construct.

Abstract: According to the method for characterizing fancy yarn, at least one characteristic of the fancy yarn is scanned along the longitudinal direction of the fancy yarn. Values of the scanning are evaluated and the results of the evaluation are outputted. The results of the evaluation are the fancy yarn parameters such as base yarn mass, base yarn diameter, slub distance, mass increase of a slub, slub diameter increase, slub diameter, slub length and/or slub total mass. On evaluation, a measurement curve is produced from the values of the scanning, and an area (A(x)) between the measurement curve and a previously determined base yarn mass is computed. A permanent increase in the course of the area (A(x)) is used as a criterion for the presence of a slub. Slubs may be differentiated from yarn imperfections in a reliable manner by way of the area (A(x)).
