  • Publication number: 20210055336
    Abstract: A method for determining system resistance of at least one power supply of a handheld medical device, the method including: a) generating at least one excitation voltage signal, wherein the excitation voltage signal comprises at least one direct current (DC) voltage signal, wherein the excitation voltage signal has a fast transition DC flank of 20 ns or less; b) applying the excitation voltage signal to at least one reference resistor having a predetermined or pre-defined resistance value, wherein the reference resistor is arranged in series with the power supply; c) measuring a response signal of the power supply; d) determining a signal flank from the response signal and determining an ohmic signal portion from one or both of shape and height of the signal flank; and e) determining the system resistance of the power supply from the ohmic signal portion.

  • Publication number: 20190167900
    Abstract: Disclosed is an ambulatory infusion device, including a control unit and an electroacoustic transducer. The control unit is configured to operate the electroacoustic transducer as noise emitter or to operate the electroacoustic transducer as noise receiver and to determine from a received noise that is received by the electroacoustic transducer a state of the ambulatory infusion device.

  • Publication number: 20070194573
    Abstract: A powertrain system comprises a compressed air supply apparatus, a compressed air engine, a rotary power conversion apparatus and an electrical power conversion apparatus. The compressed air engine is configured for extracting energy from compressed air. The compressed air engine receives compressed air from the compressed air supply apparatus and produces rotary power through extraction of energy from the compressed air. The rotary power conversion apparatus is connected to the compressed air engine and is configured for converting the rotary power of the compressed air engine to electrical power of a first specification. The electrical power conversion apparatus is connected to the rotary power conversion apparatus and is configured for converting the first specification electrical power to electrical power of a second specification different than the first specification.

  • Patent number: 6264783
    Abstract: A method of applying an inscription on a copying paper to a heat-resistant surface, such as an exterior surface of a cup, where the paper bears the inscription to be applied to the cup via heat. The heat is provided to the paper exclusively from the rear of an object to be inscribed, where the heat is provided by a halogen lamp. A sufficient temperature is generated at the surface of the object to thereby adhere the inscription to the surface, and then the paper is pulled off.
