Title: Solid state motor speed control
Inventor: NEIGER BENJAMIN
IPC: H02P25/14
Filed: 1995-01-12
Granted: 2004-03-02
Abstract: A solid state motor speed control is described that is capable of controlling a motor so that it operates quietly, eliminating annoying buzzing noises that would otherwise be generated by the motor's windings. The invention provides for motor speed control with infinitely variable speed control settings. Rather than use triacs that generate RFI noise and cause motor windings to buzz due to their inherent avalanche switching, the invention utilizes power FETs or IGBTs to provide the switching function to control power delivery to the motor load.  The power switches are controlled by an oscillator that generates a pulse train with a duty cycle controllable by the user. A filter shapes this signal into a trapezoidal control signal that drives the gate input of the power FET or IGBT switch. A kick start circuit turns the motor on initially for two to three seconds to overcome the inertia of the motor and its load. A zero crossing detector prevents the motor from being turned on except at a zero crossing of the AC source to further reduce noise.

Granted: 2005-06-14
Abstract: In a new method of molding a shoe heel a molding material is injected into a shoe heel mold and a fluid is injected into the heel body before it has set to form therein at least one enclosed hollow chamber therein which provides a different degree of resilience to heel strike forces at the location of the chamber. A plurality of closely adjacent chambers may be provided to obtain the same effect, particularly when the heel is shallow. In another method the chamber is formed by a preformed hollow element that is incorporated into the shoe heel by the molding operation.      The invention also includes apparatus for making such heels, and the heels when so made. The molded body may comprise a sole with an integral heel portion. A preformed body may be placed in the mold prior to a molding operation to ensure that the bottom chamber wall has a minimum thickness. The enclosed chamber may be vented to the ambient atmosphere or it may be sealed. The chamber when sealed may be at least partly filled with a gas or a liquid to adjust the degree of resilience, or it may be filled with a solid material of resilience different from that of the material from which the heel is molded.

Thereafter, the input signals are processed to determine whether power should be disconnected from the peripheral.  In response to a deactivation signal, the peripheral is disconnected from the power source (44). A processor (32) monitors the input signals and determines whether the peripherals should be powered or not. The processor (32) generates the activation and deactivation signals. Peripheral power is automatically turned off when the peripheral is not needed in order to minimize power consumption.
