Abstract: An exemplary latchbolt assembly includes a latchbolt, a locking sleeve, and a roller engaged between the latchbolt and the locking sleeve. The latchbolt is configured to drive the roller from a first position to a second position as the latchbolt moves from a projected position to a depressed position. The locking sleeve includes a blocking surface and a recessed portion. When the blocking surface is aligned with the roller, the locking sleeve retains the roller in the first position, thereby retaining the latchbolt in the projected position. When the recessed portion is aligned with the roller, the locking sleeve permits movement of the roller from the first position to the second position, thereby enabling depression of the latchbolt.

Abstract: A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A method and an apparatus for aligning the phases of clocks of different clock domains of an IC to enable data to be transferred synchronously across the clock domains. The present invention comprises a phase-alignment system that is adjustable via a user interface to enable the clock phases to be adjusted. A user controls the degree of alignment of the phases via the user interface. The present invention enables the phases of clocks of different clock domains to be adjusted even after the IC has been fabricated.

Abstract: A series of logic clouds is used to distribute and propagate signals traveling a relatively long distance across a data logic circuit fabric. One or more long distance signals originate from an initial logic cloud that may be located on a source data block and pass through a series of logic clouds that may be located on an intermediate data block before passing through a destination logic cloud located on a destination data block. Each logic cloud reads both stabilized logic signals and long distance signals and employs a NAND gate connected with an inverter to perform not only logical operations but also to act as a repeater between the logic clouds. The stabilized logic signals may represent signals that originate from other sources along a given data path.

By the use of embodiments according to the invention, little power is consumed, and hot electron injection as a mechanism for FET degradation is of little concern. Additionally, no specialized reference voltage is necessary, and precise layout of the circuit is not critical to proper circuit performance.

When used in conjunction with a graphical display system the low cost set mapping logic enables a memory controller to efficiently communicate with a plurality of memory devices based upon a hierarchical computation scheme. The method and apparatus provide a pseudo-optimal mapping solution. By employing a pseudo-optimal mapping solution the low cost set mapping logic greatly reduces the computational resource required to perform the mapping operation.
