  • Patent number: 10119431
    Abstract: A system (42) including a phaser (28), a motor (38), and a controller (40) for controlling the phase between a camshaft (18) and a crankshaft (16) of an engine (10). The phaser (28) is attached to the camshaft (18), is in communication with the crankshaft (16), and is configured to adjust the phase of the camshaft (18). The motor (38) actuates the phaser (28) and is operatively attached to and in communication with the phaser (28) such that rotation of the crankshaft (16) back-drives the motor (38) to subsequently generate a signal. The controller (40) is in electrical communication with the motor (38), is responsive to the signal, and uses the signal to determine the rotational speed of the motor (38) to thereby commutate the motor (38) and subsequently drive the motor (38) so as to actuate the phaser (28) and control the phase of the camshaft (18).

  • Patent number: 10072875
    Abstract: A heat concentrator device for a solar power system includes an evacuated hollow body with a bottom, side walls, a top and an airtight cap. Portions of the side walls have inwardly reflective surfaces for concentrating solar radiation into the chamber toward a heat sink, which is positioned in the bottom of the chamber. The heat sink also is hollow and has an inlet port formed in one of its opposite side walls and an outlet port formed in the other for heat transfer fluid to flow into and out of the heat sink. Circuitous passageways form a maze that connects the inlet and outlet ports thus maximizing heat transfer to/from system fluid(s) within the heat sink. The sidewalls of the chamber of the device extend below the heat sink to form a partial vacuum chamber between its bottom and the heat sink. The device is mounted to a reflective dish of a solar power system in a unique way adding additional solar energy collection efficiencies.
