Abstract: A radiation beam analyzer for measuring the distribution and intensity of radiation produced by a Cyberknife®. The analyzer employs a relative small tank of water into which a sensor is placed. The distance between the sensor and the radiation source is not varied. There are two methods to maintain the SAD (source to axis distance) constant. A first method maintains the position of detector fixed, utilizing a holder designed to retain the detector, and raises or lowers the small tank of water. A second method moves the detector up or down with a raising and lower mechanism in one direction and synchronically moves the small tank of water in the opposite direction with another raising and lowering mechanism. The second method also keeps the SAD constant. These methods position the detector relative to the radiation source to simulate the location of a malady within a patient's body.

Abstract: A radiation beam analyzer for measuring the distribution and intensity of radiation produced by a CyberKnife®. The analyzer employs a relative small tank of water into which a sensor is placed. The distance between the sensor and the radiation source is not varied. The tank of water is raised and lowered relative to the sensor to simulate the location of a malady within a patient's body. This movement of the tank permits the radiation from the CyberKnife® to be properly calibrated and adjusted for a proper treatment of a malady in a patient.

Abstract: A method of controlling a state of charge of a battery in a vehicle includes receiving a request to enter an enhanced charging mode. A target for the state of charge is increased from a normal operating target to at least one enhanced mode target. The state of charge may be controlled to the at least one enhanced mode target during a drive charging cycle and during a park charging cycle.

Abstract: The instant invention relates a convertible radiation beam analyzer for measuring the distribution and intensity of radiation produced by a radiation source. More specifically, the instant invention is a convertible radiation scanning device that includes a single guideway module constructed and arranged for attachment to dynamic phantom tank in various orientations for traversing a radiation detection probe through a radiation beam along various axes to determine radiation intensity and distribution throughout the beam.

Abstract: A locking device and a headrest are disclosed. The locking device includes spring elements, which can be engaged in at least one locking position and the locking device can be displaced in relation to at least two retaining bars that have a large number of recesses. The spring elements co-operate with the recesses in such a way that the engagement of the spring elements in their locking position locks the locking device in relation to the retaining bars. According to the invention, the spring elements are configured in such as way that the retaining bars are locked by the mechanical fixing of the spring elements in their central zone or by exertion of a force on the spring elements in their central zone.

Abstract: The instant invention is a modular radiation beam analyzer for measuring the distribution and intensity of radiation produced by a radiation source. More specifically, the instant invention is a modular radiation scanning device that includes up to three modules. By selecting and assembling a predetermined number of modules a radiation detector may be manipulated through up to three axes for radiation beam scans as well as direct Tissue Maximum Ratio (TMR) and/or Tissue Phantom Ratio (TPR) scans.

Abstract: The present invention meets these objectives providing an IDG hydraulic system that utilizes in flow series arrangement a scavenge pump, a spool valve and a boost pump. When spool valve detects an interruption in the supply pressure to the boost pump due to an adverse “g” condition, it reconfigures the system to a closed loop system. In this mode, the oil returning from the CVT is re-circulated back to the boost pump instead of back to the scavenge pump. Oil lost to leakage is replenished by an oil accumulator that use the gas pressure in the IDG's casing to expel fluid from the accumulator into the recirculating flow.

Abstract: The present invention is a dynamic radiation scanning system for detecting radiation dosimetry of a beam emitted along an axis from a radiotherapy treatment machine and a method for its use. The system contains a dosimetry probe to sense photons and electrons, a dynamic phantom body formed from a material having a density approximating that of the human body, a gantry mounting assembly rigidly attached to the radiotherapy machine for positioning of the phantom body, and a lead screw assembly rigidly affixed to the gantry for providing coplanar movement of the dynamic phantom within a plane perpendicular to the axis of radiation emission. Movement of the dynamic phantom through a series of locations is carried out at varying depths and angles so as to provide sufficient data to determine variations in beam uniformity, thereby providing for simple and reliable testing and calibration of the machine.
