  • Patent number: 11744635
    Abstract: A system includes a medical device and a charging device. A sterile barrier may be interposed between the medical device and the charging device. The medical device includes an integral power source and an active element. The charging device is configured to charge the integral power source. The charging device may charge the integral power source through direct contact between features of the charging device and features the medical device. The charging device may alternatively charge the integral power source wirelessly, such as through inductive coupling. The medical device may include conductive prongs that are retained by the charging device. The charging device may physically couple with the medical device via magnets. The medical device and the charging device may be provided together in a sterile package as a kit. The kit may also include a reclamation bag to facilitate reclamation of electrical components.

  • Publication number: 20230263548
    Abstract: A method for controlling an operation of an ultrasonic blade of an ultrasonic electromechanical system is disclosed. The method includes providing an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade via an ultrasonic waveguide; applying, by an energy source, a power level to the ultrasonic transducer; determining, by a control circuit coupled to a memory, a mechanical property of the ultrasonic electromechanical system; comparing, by the control circuit, the mechanical property with a reference mechanical property stored in the memory; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the comparison of the mechanical property with the reference mechanical property.

  • Patent number: 5349143
    Abstract: A reversible electric switch has movable contacts on opposite ends of a rotor adapted for interengagement with diametrically disposed pairs of stationary contacts. Intermittency or rocking of the movable contacts with respect to the stationary contacts is eliminated by extending drive pins from the rotor into the slot provided within the contact face of the movable contact, such pins passing only partially through the thickness of such contact face. Accordingly, the force applied to the movable contacts to achieve rotation thereof is substantially at the interface between the stationary and movable contacts, substantially eliminating any force couple or moment thus precluding any rocking of the movable contact upon the rotor or other relative movement between the two.

  • Patent number: 5051613
    Abstract: A low voltage DC one-shot circuit momentarily increases the voltage applied by a NiCad battery pack to the gate of a MOSFET. A charge pump generates a supply voltage to a monostable multivibrator which is manually actuated by a switch to emit an output pulse of fixed amplitude and pulse width. The pulse is passed through a level shift network where it is summed with a bias voltage for application to the gate of the MOSFET.

  • Patent number: 4466686
    Abstract: A connection adapter module for a wire trap switch, trigger speed control, or the like that plugs into the wire trap system and provides screw clamp connections to the control for a portable electric tool such as a drill, sabre saw, or the like, enabling the tool to be rewired or the control replaced by a customer with a standard screwdriver, comprising an insulator body carrying a plurality of connector elements and which can be "piggy-backed" on the control, connector elements generally comprising inserts in the insulator body including a barrel portion having a screw threaded through the wall thereof for receiving and clamping a wire therewithin and a thin wire-like projection or pin portion extending longitudinally therefrom projecting out of the insulator body to be engaged within the switch or control wire trap.

  • Patent number: 3931558
    Abstract: A circuit is disclosed for controlling and regulating the speed of a D.C. motor fed from a single-phase A.C. supply. A full-wave power bridge using two diodes and two silicon controlled rectifiers (SCR's) supplies unfiltered rectified A.C. to the motor. A first programmable unijunction transistor (PUT) is used to trigger the SCR's in response to a timing capacitor voltage applied to its anode. The timing capacitor is charged from a zener-regulated, full-wave bridge source through a speed-control resistor and thus provides triggering of the SCR's at a phase angle determined by said speed-control resistor. To obtain consistent triggering at the same phase angle, a second PUT is used to reset the voltage on the timing capacitor to zero at the end of each half cycle of the A.C. voltage to insure that the initial charge condition of said capacitor is always the same.
