|20120121369||LIFT GATE LOAD ELEVATOR WITH COLUMNAR POWER ASSEMBLIES - A lifting system includes a vertically extending parallel pair of fixedly spaced apart guide surfaces, a linear actuator suspended vertically between said pair of guide surfaces, a vertically elongate runner member having a pivotal connection to a lower end of said linear actuator to be vertically reciprocated by said actuator, a load bearing member at a lower end of said runner member at a location spaced downwardly from said pivotal connection and a vertically spaced apart pair of sliding contact members on said runner member for relatively slidable contact with said pair of guide surfaces during vertical reciprocation of said runner member by said actuator. Each of said contact members comprises a projecting contact pad having a concave surface for slidable contact with one of said guide surfaces.||05-17-2012|
|20100002351||METHOD AND APPARATUS FOR CONTROLLING A DC LOAD - A method and apparatus is provided for controlling power to a DC load ON and OFF. The apparatus has a first FET bank, a second FET bank, connected in series with a first FET bank, and a controller. The controller is configured for detecting a operational failure of at least one of the FET banks, and turning at least on of the FET banks OFF in response, thereby turning power to the DC load OFF. The controller may also detect a operational failure of one of the FET banks, and turn the other FET bank OFF in response, thereby turning power to the DC load OFF.||01-07-2010|
