Patent number: 11134547Abstract: Systems and methods for maintaining the illumination intensity of one or more LEDs above a minimal intensity level. The systems and methods may include: (1) a current regulator for regulating the current in a circuit; (2) a voltage source for applying current to a circuit; (3) an LED with a minimal intensity level that correlates to a set-point temperature; and (4) a thermal sensor that is in proximity to the LED and adapted to sense a temperature proximal to the LED. The thermal sensor may transmit a signal to the current regulator if the sensed temperature exceeds the set-point temperature. Thereafter, the current regulator may take steps to regulate the current in order to maintain the LED illumination intensity above the minimal intensity level.Type: GrantFiled: December 10, 2019Date of Patent: September 28, 2021Assignee: Luminator Holding LPInventors: Vadim Zlotnikov, John B.

Patent number: 7067995Abstract: Method and system are disclosed for compensating for color variations due to thermal differences in LED based lighting systems. The method and system involves characterizing the LEDs to determine what PWM (pulse-width modulation) is needed at various operating temperatures to achieve a desired resultant color. The characterization data is then stored in the microprocessor either in the form of a correction factor or as actual data. When an operating temperature that is different from a calibration temperature is detected, the characterization data is used to adjust the PWM of the LEDs to restore the LEDs to the desired resultant color.Type: GrantFiled: August 27, 2003Date of Patent: June 27, 2006Assignee: Luminator, LLCInventors: John B.

Patent number: 5726815Abstract: An apparatus for aligning the object focus of an elliptical reflector, such as positioned within the filament tube of a filament irradiating unit, with a directional axis, such as the centerline of the filament as it travels through the tube. The apparatus includes a support assembly for mounting the tube in a precisely fixed position, and three adjustable mounting assemblies connected to the support assembly at three spaced apart connection points for mounting the support assembly on a stationary base. Each of the mounting assemblies includes a pair of linkages each of adjustable length and forming two sides of a triangle with its apex at the point of connection to the support assembly.Type: GrantFiled: April 12, 1996Date of Patent: March 10, 1998Assignee: Fusion UV Systems, Inc.Inventors: John B.

Patent number: 5061176Abstract: An apparatus and process for positioning and for simultaneously oscillating a plurality of heater probes within a plurality of heat exchanger tubes mounted in a tubesheet of a nuclear steam generator is disclosed herein. The apparatus generally comprises a frame, a plurality of probe drivers mounted onto the frame, wherein each driver includes a pneumatically operated, bladder-type gripper for selectively gripping and ungripping the push-cable of one of the heater probes, as well as an oscillating mechanism powered by a variable voltage d.c. motor. A controller connected between the d.c. motor and a power source separately controls the frequency and the amplitude of the cycle that the oscillating mechanism moves the gripper in, and further controls the alignment between the midpoint of the oscillatory cycle and a selected point along the longitudinal axis of the tube.Type: GrantFiled: October 18, 1990Date of Patent: October 29, 1991Assignee: Westinghouse Electric Corp.Inventors: Paolo R. Zafred, David A. Snyder, John B. Gunter, William C. Ritz
