Abstract: A method of validating a compensator for use in a radiation therapy machine to treat a cancer patient involves determining a radiation treatment plan based on a compensator description file that includes data representative of an actual machined surface of the compensator. The plan includes operating parameters of the radiation therapy machine, and this plan is compared against actual radiation measurements taken during a non-patient test of the radiation therapy machine with the compensator mounted to the machine. If the comparison results in a match, the compensator is validated for use in the radiation therapy machine to treat the cancer patient.

Abstract: A patient-specific compensator is created from solid particulates on-site at a radiation treatment facility and then used there at that facility in conjunction with a radiation therapy machine to deliver radiation therapy to a cancer patient. After use, the compensator can be broken down into loose solid particulates at the facility, and another compensator can be created on-site at the facility from those particulates and used in the radiation treatment of a different cancer patient at the facility.

Abstract: A compensator is used with a radiation therapy machine to treat a cancer patient. A three-dimensional surface of the compensator is defined by obtaining a radiation dose requirement created by a treatment planning system associated with the radiation therapy machine and determining a plurality of grid elements based on that radiation dose requirement. At least one of a plurality of points on each of the plurality of grid elements is connected with at least one of the plurality of points on another one of the plurality of grid elements to form a representation of the three-dimensional compensator.

Abstract: A folding decoy or other representation is formed of a single sheet of laminated material having opposite face plies and a central core sandwiched therebetween. Preferably, a waterproof, plastic material having a corrugated core is used, but other laminated materials may also be used as desired. The decoy is formed by cutting out a planform silhouette and then making a series of scores which extend through one of the face plies and the core material, leaving the opposite face ply uncut. The scores are made from opposite sides of the sheet to provide for folding in either direction, as desired. A series of such scores may be made, with different scores providing for different folds in different directions and orientations. This allows a person to use a single decoy blank to form decoys having different postures as desired, to add greater realism to a group of decoys.

Abstract: A mounting plate that is secured to a rear fender of a motor cycle to hold a sissy bar. The plate is secured to the rear fender using pre-existing holes in the rear fender. The plate comprises a first curved portion, a second curved portion integral with the first curved portion and located at one end of the plate and defining a plurality of holes therein, and a third curved portion integral with the first curved portion and located at an opposite end of the plate and extending perpendicular to a longitudinal axis of the plate. Attached to the third curved portion is a pair of mounting brackets for retaining the sissy bar.

Abstract: Bandwidth optimization between a microprocessor and a disc drive controller. Method and apparatus are disclosed for synchronizing asynchronous microprocessor writes to synchronous read/write channel operation. In this synchronization, bandwidth of the microprocessor is equal to or greater than the bandwidth of the disc controller. Both no ready line and ready line implementations are described.
