摘要： A manually powered apparatus includes a mechanical energy input device that releases mechanical energy. The mechanical energy input device has first and second mechanical energy delivery cycles. A generator is mechanically coupled to the mechanical energy input device. The generator converts released mechanical energy to electrical energy. The electrical energy includes first current levels and second current levels that decrease over time. The generator supplies the first current levels in response to the first mechanical energy delivery cycle. The second current levels are supplied in response to the second mechanical energy delivery cycle. A load is connected to the generator. The load requires a predetermined current for operation. The first current level is greater than the predetermined current, and the second current level is less than the predetermined current. An electrical energy storage device is connected between the generator and the load. The electrical energy storage device is charged during the first mechanical energy delivery cycle, and the electrical energy storage device is discharged during the second mechanical energy delivery cycle. An isolator is connected between the electrical energy storage device and the load. The isolator minimizes reverse current flow from the electrical energy storage device to the generator. A disconnector is electrically connected between the electrical energy storage device and the load. The disconnector decouples the load from the electrical energy storage device to prevent the electrical energy storage device from completely discharging.

摘要： A spring motor for driving an electric power generator with constant power includes a crank-up spool, a take-up spool, and a relatively wide, flat tape spring which winds in a relaxed condition on the take-up spool. In one form, the spring has a width which varies approximately linearly from one end to another end so as to generate a constant torque at a fixed radius from an axis of the crank-up spool as the spring unwinds. In another form, the spring width is constant and a separate drum is driven by contact with the unwinding spring, with the separate drum driving an output shaft. In still another form, an idler wheel is driven by contact with the spring and the output shaft is driven from the idler wheel through gear contact with the periphery of an output drum mounted on the output shaft.

摘要： A technique for acquiring desired image data in an imaging system comprising at least one radiation source and a detector is described. Initially, preliminary image data corresponding to an object may be acquired. Further, at least one parameter associated with the radiation source and corresponding to a particular view angle of the radiation source may be determined based on the preliminary image data and a priori information. Similarly, at least one parameter associated with the detector and corresponding to the particular view angle may be determined based on a priori information and the preliminary image data. Efficient operating modes of the radiation source and the detector corresponding to the particular view angle may be selected based on the determined parameters to achieve a desired system performance.

The ED detector includes a first layer having a first thickness, wherein the first layer comprises a semiconductor configurable to operate in at least an integrating mode and a second layer having a second thickness greater than the first thickness, and configured to receive x-rays that pass through the first layer. The system further includes a data acquisition system (DAS) operably connected to the ED detector and a computer that is operably connected to the DAS. The computer is programmed to identify saturated data in the second layer and substitute the saturated data with non-saturated data from a corresponding pixel in the first layer.
