Patent number: 6050092Abstract: A Stirling cycle machine control system includes an energy converter having a moving member. A detector is operatively associated with the moving member. The detector is configured to detect stroke of the moving member. A converter circuit is coupled with an output of the energy converter and is operative to convert output from AC to DC. A regulator is coupled with the converter circuit and a useful load, and is operative to regulate DC voltage. A controllably variable load member is coupled to the converter circuit and is operative to adjust load to the energy converter. Adjustment of the load to the energy converter regulates power output of the energy converter which in turn controls movement of the moving member. Control circuitry is signal coupled with the detector and the load member. The control circuitry is configured to receive a feedback signal correlated with the detected stroke of the moving member.Type: GrantFiled: August 28, 1998Date of Patent: April 18, 2000Assignee: Stirling Technology CompanyInventors: Curtis Genstler, Ian Williford, Howard H.

Patent number: 5532525Abstract: A secondary power system eliminates the need for an automatic transfer switch and permits simultaneous supply from different sources. Primary power is rectified and connected to a DC bus, an AC generator has its output rectified and connected to the DC bus, and a storage battery is also connected to the DC bus. Current on the DC bus is inverted to AC to provide an uninterrupted power supply. The system is connected to a household electrical system by a power distribution panel which can be installed in a home prior to the secondary power system and can facilitate installation of the secondary system. The distribution panel can selectively bypass the secondary system and can disconnect non-vital loads when primary power is not available. The generator is powered by an engine using gasoline, natural gas or water, which can also power other systems, such as air conditioning, with exhaust heat or rotary motion.Type: GrantFiled: June 2, 1994Date of Patent: July 2, 1996Assignee: Albar, Inc.Inventors: Frederick Kaiser, Howard H.

Patent number: 5010469Abstract: An uninterruptible power supply is disclosed having an inverter that operates on either high voltage d.c. supplied by a line-powered power supply or on low voltage d.c. batteries. With line power, the inverter operates as an H-bridge inverter. With battery power, the battery voltage is applied to a smaller portion of the inverter's transformer primary. The changeover from line to battery power is determined by when an intermediate voltage tapped from the transformer drops below the battery voltage.Type: GrantFiled: May 9, 1990Date of Patent: April 23, 1991Assignee: AlbarInventor: Howard H.
