Patent number: 9835649Abstract: A reconfigurable load board clamp is disclosed. The reconfigurable load board clamp includes first and second slotted ends; first and second opposing sides laterally coupled to the first and second slotted ends; and a MCPCB pin board removably coupled to the first and second slotted ends. The pin board includes a card edge connector plugged into an end of the pin board and multiple spring-loaded pin connectors. In implementations, multiple pin boards may be removed and added to the reconfigurable load board clamp to form a pin array suitable for a particular load board.Type: GrantFiled: June 26, 2015Date of Patent: December 5, 2017Assignee: Vektrex Electronic Systems, Inc.Inventor: Jeffery Neil Hulett

Publication number: 20130313972Abstract: A multicolored LED luminaire module is provided that can be controlled using a single driver and only two wires. The LED luminaire module comprises a plurality of LEDs and a sequencer. The sequencer connects each LED to the circuit in a predetermined order. Synchronously with the sequencer, the driver transmits a control signal comprising a time division multiplexed (TDM) signal that combines the driving currents for each LED into one TDM signal. The sequencer and TDM rate are sufficiently fast such that the light emitted by the LED luminaire appears to be the combined light from all the LEDs.Type: ApplicationFiled: March 26, 2013Publication date: November 28, 2013Inventor: Jeffery Neil HULETT

Patent number: 8503145Abstract: A fault protected current source is provided that can be used to safely drive LEDs in reliability test systems. The current source is includes circuits and processes that detect the common faults found in LED reliability test systems. After a fault is detected, the current source shuts down drive before destructive spikes are produced. Because only true LED failures are counted, this fault protected current source can be used to construct reliability test systems that produce more accurate reliability test data.Type: GrantFiled: April 13, 2011Date of Patent: August 6, 2013Assignee: Vektrek Electronic Systems, Inc.Inventor: Jeffery Neil Hulett
