  • Patent number: 10709469
    Abstract: A method of conserving energy in a surgical instrument that includes a segmented circuit having a plurality of independently operated circuit segments, a voltage control circuit, an energy source, a memory, and a processor coupled to the memory. The processor is configured to control a state of a circuit segment of the plurality of circuit segments. The state can be an energized state or a deenergized state. The method includes transmitting an energizing signal from the processor to a voltage control circuit, receiving the energizing signal by the voltage control circuit to apply a voltage to a circuit segment of the plurality of circuit segments, applying the voltage to the circuit segment by the voltage control circuit to cause the circuit segment to transition from the deenergized state to the energized state in accordance with an energization sequence that is different from a deenergization sequence.

  • Patent number: 10631083
    Abstract: A speaker assembly can include a speaker and one or more actuators operatively positioned to cause the position and/or the orientation of the speaker to be adjusted. The one or more actuators include a bladder. The bladder can include a flexible casing. The bladder can define a fluid chamber. The fluid chamber can contain a dielectric fluid. The one or more actuators can include a first conductor and a second conductor operatively positioned on opposite portions of the bladder. The one or more actuators can be configured such that, when electrical energy is supplied to the first conductor and the second conductor, the first conductor and the second conductor can become oppositely charged. As a result, the first conductor and the second conductor are electrostatically attracted toward each other to cause at least a portion of the dielectric fluid to be displaced to an outer peripheral region of the fluid chamber.
