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: Flags with at least one printed side, hemmed side edges, and a first end edge including a flagpole sleeve are made from a continuous sheet of textile material by cutting flag-length sections from the sheet, each section having hemmed side edges and at least one printed side, and forming a flagpole sleeve along the first end edge of the flag section. Formation of the flagpole sleeve after the flag section is printed, as opposed to printing after formation of the flagpole sleeve as in the prior art, results in improved production speeds and improved products. The sleeve may be formed by folding over the first end edge, or by separately attaching a loop of textile material.

Abstract: A device for disconnecting an electric appliance or a component thereof from a source of electricity including a circuit connecting the appliance or component thereof to a power source through a relay or other component to open the circuit; and a timer circuit connected to the relay. The timer circuit includes a processor for setting the timer circuit, and a manually operated switch in communication with the processor. The timer circuit is activated for a predetermined time increment by closing the switch, and the relay is closed while the timer circuit is activated. When the switch is closed again while the timer circuit is activated, an additional time increment is added to the activation period.
