An ergonomic and aerodynamic bicycle handlebar system having appropriate sweep angles and slope angles, embodiments of which can vary both for the type of application and the width of the bar, provides improved energy efficiency, comfort and increased center of gravity control. Flare angle and drop angle can also be adjusted for particular applications. The handlebar may be made of carbon fiber or other suitable materials. Various alternative embodiments are disclosed for drop handlebars and mountain bike handlebars.

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide variable controlled dose per pulse to permit scanning a portion of a vehicle at a dose safe for humans and scanning a cargo portion of a vehicle at substantially increased dose per pulse.

Scanning linear accelerator system for producing X-rays of variable controlled dose per pulse

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of pulses having different energy levels or different dose.

Linear accelerator system for stable pulsing at multiple dose levels

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of pulses having different energy levels or different doses.

An image-guided radiotherapy system adapted to be juxtaposed adjacent a CT scanner comprises a frame having an orifice adapted to permit passage therethrough of a couch on which a patient is positioned, together with a gantry assembly rotatably mounted on the frame in which the gantry assembly comprises a shielding cylinder having an orifice therethrough in alignment with the orifice in the frame. The shielding cylinder has affixed thereto a linac-based treatment head configured to provide radiotherapy, and a beamstop positioned angularly opposite the treatment head to absorb radiation from the treatment head. The shielding cylinder provides sufficient shielding of radiation scattered from the patient and the remainder of the system to not require a conventional vault. In some embodiments an arch may be used instead of a cylinder.

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of interleaved pulses having different energy levels, for example alternating 4 MeV and 6 MeV pulses or other energies where the difference in levels is at least approximately 1 MeV and less than approximately 5 MeV. The pulse repetition rate can be 100-400 pulses per second or more. In an embodiment, a cool down calculation is combined with automatic frequency control to provide stable energy and dose per pulse even upon restarting of pulsing after an 'off' period of indeterminate duration.
