  • Patent number: 10850801
    Abstract: A pedal-electric bicycle utilizes an e-clutch to prevent a motor of the pedal-electric bicycle that is fixedly engaged to a drivetrain of the pedal-electric bicycle from resisting movement of the drivetrain when the motor is not transferring power to the drivetrain. The e-clutch causes the motor to operate at a minimum torque level to overcome the internal resistance thereof. The use of an e-clutch beneficially permits the elimination of a mechanical motor clutch, thus reducing complexity, cost, and weight of the pedal-electric bicycle.

  • Patent number: 8747335
    Abstract: A bodily fluid sampling device is operable to breach the skin surface and allow bodily fluid to emerge from the breach location. The bodily fluid sampling device further evaluates the amount of bodily fluid emerged from breach location and determines whether the amount is sufficient or insufficient for a particular purpose, such as sampling and testing. The determination is accomplished automatically without moving the device. The user may also intervene to perform a variety of tasks following the determination of the amount of bodily fluid.

  • Publication number: 20120000569
    Abstract: A reservoir filling aid for a reservoir of a medical infusion pump is disclosed. The reservoir filling aid comprises a main body for supporting the reservoir during the filling of the reservoir with a medical serum and a supply vial adapter end positioned at a first end of the main body. The supply vial adapter end comprises a plurality of flexible tabs extending from the supply vial adapter end for interfacing with a supply vial containing the medical serum and a shaped ring for housing the plurality of flexible tabs and the supply vial while in a closed configuration to establish a fluid connection between the supply vial and the reservoir. The interior of the supply vial adapter end may also have a spiral track for additional security. A removable adapter may be fitted on the top of small supply vials.
