    摘要: A control circuit and method for controlling the electrical characteristics of an input/output (I/O) circuit such as an output driver to account for variations in fabrication process, supply voltage, and/or temperature (PVT) conditions includes a PVT controller having appropriate control logic to permit PVT compensation to be observed, tested, and selectively adjusted. The PVT controller permits selection between PVT sensing circuit-provided control signals and control signals stored in a hardware register for controlling drive strength. The PVT controller further provides the capability to offset the selected drive strength by a fixed amount and select whether or not the offset is applied and permits full testability and observability of the selected control signal, an offset value applied thereto, and the resulting output signal.

    摘要: A compensation circuit comprises a reference circuit including a reference NMOS device and a reference PMOS device. The reference circuit is operative to generate a first reference signal and a second reference signal, the first reference signal being a function of at least one of a process characteristic, a voltage characteristic and a temperature characteristic of the reference NMOS device, and the second reference signal being a function of at least one of a process characteristic, a voltage characteristic and a temperature characteristic of the reference PMOS device. The compensation circuit further comprises a control circuit connected to the reference circuit. The control circuit is operative to receive the first and second reference signals and to generate one or more output signals for compensating for a variation in at least one of a process characteristic, a voltage characteristic and a temperature characteristic of at least one NMOS device and at least one PMOS device in a circuit to be compensated, which is connectable to the control circuit, in response to the first and second reference signals, respectively.

    摘要: A PET event position calculation method using a combination angular and radial event map wherein identification of the radial distance of the event from the centroid of the scintillation crystal with which the event is associated as well as angular information is performed. The radial distance can be converted to a statistical confidence interval, which information can be used in downstream processing. More sophisticated reconstruction algorithms can use the confidence interval information selectively, to generate higher fidelity images with higher confidence information, and to improve statistics in dynamic imaging with lower confidence information.

    摘要: A propeller having one or more blades eccentrically mounted to a shaft dynamically changes the blade pitch to produce free vortices in a fluid. For extracting energy from a moving fluid, the fluid flow acting on the blades rotates the propeller, while the pitch changes create a fluid flow pattern known as a von Karman vortex street. The resulting time averaged flow field distant from the propeller is a wake flow, and the energy of the fluid flow can be efficiently converted to rotation of a shaft driven device. For propulsion, applied shaft rotation and the dynamic pitch change in a fluid together create a flow pattern that is the inverse of the von Karman vortex street. For either energy extraction or propulsion, the propeller is particularly suited for low flow speeds, where the effects of low Reynolds number induced flow separation on blades may make other propellers inefficient.
