Patent number: 4843366Abstract: A wall box mounted voltage controller used in conjunction with a remotely located dimmer module for controlling multiple loads. The controller utilizes a printed circuit board structure and a multiplicity of control operators extendable from the printed circuit board structure. Each operator is linked to a potentiometer which in turn generates a electrical signal to control the intensity of the load via the dimmer module. High and low trim mechanisms for each signal are supported to the printed circuit board structure and are readily available for mechanical adjustment.Type: GrantFiled: February 18, 1988Date of Patent: June 27, 1989Assignee: Prescolite Inc.Inventors: Robert F.

Patent number: 4803586Abstract: A wall box mounted remotely operated voltage module utilizing a low voltage DC control signal which is remotely generated. A power semi conductor device is triggered to deliver a predetermined amount of power from the source of AC electrical power to a load. The AC electrical power is rectified and transformed to produce a low voltage rectified DC signal. A comparator generates a triggering signal to the power semi conductor utilizing the low voltage rectified DC signal and remotely generated low voltage DC control signal as imputs. The comparator also serves as a compensator for changes in the voltage of the AC electrical power from the source.Type: GrantFiled: November 30, 1987Date of Patent: February 7, 1989Assignee: Prescolite, Inc.Inventors: Jim Tabor, Richard Counts

Patent number: 4772825Abstract: A panel controlling multiple lighting intensities of a multiplicity of lights in conjunction with a remote lighting dimmer module which utilizes operators mechanically movable to operate potentiometers. Each potentiometer is capable of setting an intensity level of a particular light of the multiplicity of lights. A display is also employed which indicates a lighting level of each of the multiplicity of lights associated with each operator and corresponding potentiometer. The operators and display are supported by a chassis which is mountable in an electrical wall box. Information may be stored which defines a lighting scene in terms of an intensity level of each light of the multiplicity of lights which is set by the operators in the chassis. The intensity level information may be retrieved and transported to a dimmer module which sets the intensity level in each light. One scene may be set into the multiplicity of lights while another scene may be previewed on the display on the chassis.Type: GrantFiled: July 28, 1986Date of Patent: September 20, 1988Assignee: Prescolite Inc.Inventors: Jim Tabor, Richard Counts
