Abstract

This invention relates to the remote wireless control of electrical AC and/or DC appliances, devices, apparatus without relay attachments to the appliance or to the motor driving the appliance or device or modification to the appliance or device. The level of operation of devices may further be controlled remotely, wirelessly, via amplitude modulation, phase, or pulse, or by increasing or decreasing frequency. Motor speed may further be controlled by a beam of visible or invisible light, or by preprogrammed signal eminating from a tape recording or other programmed material. The operation of one or more devices may be also varied automatically remotely, wirelessly, in or out of sequential order.
