Abstract: A wind power generation assembly having a rotatable base. Attached to the base are a plurality of arcuate panels that surround a turbine assembly. The center axis of the base and the center axis of the turbine assembly are offset. The panels are positioned to capture the wind and redirect the wind energy to the turbine assembly.

Abstract: A patient support device of a radiation therapy treatment system includes an electromechanical motor and control system for moving the support device. The control system utilizes regenerative braking concepts, converting the motor into a generator as the support device is moved such that no matter the load, the support device will be moved at a constant speed. The control system also allows for moving of the support device in the powered off situation (i.e., when there is no power to the support device).

Abstract: A method and system configured to substantially synchronize two opposite ends of a table assembly of a radiation therapy treatment system. The system includes a lateral motion control system coupled to the table assembly and configured to detect positions of the two opposite ends of the table assembly and to substantially synchronize the positions as the table assembly is laterally moved with respect to a gantry of the radiation therapy treatment system.

Abstract: A pen-type mouse includes a shoe that is movable with respect to a flat surface, an elongated body, and a joint connecting the shoe and the body such that the body is at least partially rotatable with respect to the shoe about a first axis that is generally parallel to the flat surface and about a second axis that is also generally parallel to the flat surface, but is prevented from rotating about a third axis that is generally perpendicular to the flat surface. The pen-type mouse can include a position detection module for determining a position of the shoe at each of a plurality of times as the shoe is moved, and a link for communicating the determined positions to a computing device.

Abstract: The energy crisis that has long been accepted in the scientific community is being embraced by society along with an increasing sense of environmental responsibility. Solar will be a large part of the renewable energy revolution. Solar harnessing technology has primarily focused on solar farms or on off-grid, residential use and mostly on warm, dry climates that have high percentages of clear sky. Cooler, wetter climates have seen less research and resources dedicated to solutions and indeed have a different set of requirements than for traditional desert solar farms. This invention provides a simple tracking solar solution that combines both concentrated photovoltaic CPV and traditional photovoltaic (PV), although the solution can use only CPV or PV. The invention reduces the structural and drive demands by shielding the solar collecting mechanisms inside an enclosure and then connecting the collecting mechanisms in synchronous arrays.

Abstract: A patient support device of a radiation therapy treatment system includes an electromechanical motor and control system for raising and lowering the support device in the Z direction. The control system utilizes regenerative braking concepts, converting the motor into a generator as the support device is lowered such that no matter the load, the support device will be lowered at a constant speed. The control system also allows for lowering of the support device in the powered off situation (i.e., when there is no power to the support device).

Abstract: The present invention provides a detector for use in medical and industrial applications for detecting high energy radiation, especially for use in tomotherapy and other image-guided radiotherapy systems. The detector is preferably housed in an enclosure. A plurality of detector elements are installed within the enclosure. The detector elements preferably include a substrate, a readout electrode layer deposited on at least one surface of the substrate, an amorphous selenium layer deposited on at least one surface of the readout electrode layer, and a high voltage electrode layer deposited on at least one surface of the amorphous selenium layer.
