Abstract: Methods and systems of radiosurgical treatment include rotating one or both of a first gantry component and a second gantry component while transmitting a therapeutic treatment beam so as to deliver a therapeutic radiation dose to a target tissue of a patient from one or more arcs extending along a treatment sphere. The first gantry component is rotatable about a first axis and a second gantry component is interfaced with the first gantry component such that rotation of the first gantry component rotates both the first and second gantry components about the first axis. The second gantry component is independently rotatable about a second axis. The method includes coordinating movement of the first and second gantry components along the respective first and second axes so as to allow a trajectory of the therapeutic treatment beam to intersect the target tissue from multiple directions along the treatment sphere.

Abstract: A method, graphical user interface, and computer program product on a computer readable medium are disclosed for presenting a user with a display of a skew clock tree for a digital circuit design. In the preferred embodiment, a computer system receives timing analysis data for a digital circuit. The computer system determines a propagation time delay between a first clock root and each of a plurality of clock sinks of the digital circuit associated with the first clock root based on the timing analysis data. The computer system then displays the first clock root and each clock sink associated with the first clock root of the skew clock tree along an axis representing time delay. In the displayed skew clock tree, each clock sink is positioned along the axis relative to the first clock root based on each clock sink's determined propagation time delay.

The method and system convert at least one of a predetermined plurality of motion patterns imparted by an operator of the system to the transducer into the operational command signal.

Abstract: A method for estimating the average-case activity in a digital circuit includes the steps of identifying one or more predesignated types of circuit elements in the digital circuit, and propagating activity values through any identified circuit elements using a predetermined formula.

Abstract: A method for estimating the average-case activity in a digital circuit includes the steps of identifying a state machine in the digital circuit, and propagating activity values through the state machine to obtain activity information at an output of a flop in the state machine using a predetermined formula.

Abstract: A method for estimating the average-case activity in a digital circuit includes the steps of assigning initial activity values to outputs of flops in the digital circuit, and repeatedly updating the activity values in an iterative procedure until a predetermined termination criterion is met, wherein the updating of the activity values uses a combination of standard probability updating techniques and predetermined formulae for obtaining the activity values of predesignated types of circuit elements in the digital circuit.

Abstract: An ergonomically superior endoscopic suction-irrigation instrument for surgery comprises a telescope sheath connected at an adjustable angle, preferably approximately 30°, to a vertically elongated handle having thumb-operated irrigation and suction valves and a hook for supporting the handle from the surgeon's hand when the surgeon's grip on the handle is loosened. The instrument is especially suited for sinus surgery.
