Abstract: The present invention includes novel apparatus and methods for recovering energy from water waves. An embodiment of the present invention may include a buoy, a shaft, and an electric power generating device. The shaft may be coupled to the buoy such that when the buoy moves vertically in response to a passing wave, the shaft rotates. The shaft may be coupled to the electric power generating device such that when the shaft rotates, the generating device produces electric power. Once electric power is generated, it may be delivered to shore, where it is stored, used to power a device, or delivered to a power distribution grid.

Abstract: A wave energy recovery system includes a plurality of motion translating assemblies, each assembly includes a buoy coupled to a shaft segment. The shaft segments form a shaft that is coupled to an electric power generating device. Each shaft segment is coupled to a buoy such that when the buoy moves vertically in response to a passing wave, the shaft segment rotates, thus rotating the shaft. The shaft is coupled to the electric power generating device such that when the shaft rotates, the generating device produces electric power. Once electric power is generated, it is delivered to shore, where it is stored, used to power a device, or delivered to a power distribution grid.

Abstract: An exercise device comprising a base and a platform rotatably tiltably connected to the base, wherein the invention includes a first continuous passive motion embodiment and a second continuous active motion embodiment. The continuous passive motion exercise device (e.g. non-motorized) may utilize the nested engagement of a concave surface located in the base and a convex surface extending from the platform to provide a rotatable tiltable connection therebetween. The device may also utilize at least one roller bearing located within the base to assist in permitting the rotatable tiltable motion of the platform relative to the base. The continuous active motion exercise device (e.g. motorized) utilizes a motor housed within the base to drive the rotatably tiltably connected platform.

Abstract: A rotatable shaft assembly comprises a shaft having a generally cylindrical first section and a generally cylindrical second section. The diameter of the first section is greater than the diameter of the second section. A shoulder having a generally annular face extends between the first and second sections of the shaft. A member to be mounted on the shaft, such as an impeller blade, has a face and an axial bore sized to receive the second section of the shaft and is adapted to confront the face of the first section of the shaft when the member is mounted on the shaft. The member is secured against rotation relative to the shaft by a plurality of pins. Each pin comprises a pin head and a pin shaft formed integrally with, and extending generally perpendicularly from, the pin head. A plurality of bores are formed radially symmetrically in the second section of the shaft proximate the first section and adapted to securely receive the pin shafts in a press fit.

Abstract: A gas blower comprises a generally cylindrical housing containing a generally annular radially symmetric impeller chamber and a generally annular and generally radially symmetric plenum chamber. The housing has a gas inlet opening to the impeller chamber and a gas outlet opening from the plenum chamber. The radially outer portion of the impeller chambers in fluid communication with the radially outer portion of the plenum chamber. The blower further comprises a rotatable drive shaft extending axially within at least a portion of the housing and an impeller mounted on the drive shaft for rotation within the impeller chamber. The impeller is mounted for a generally axially intake of gas from the inlet opening and a generally centrifugal radially symmetric exhaust of the gas within the axial component in the axial direction opposite to the direct of the gas intake.
