  • Patent number: 8907685
    Abstract: Disclosed is a circuit arrangement for determining a temporal change of an output voltage of a half-bridge circuit during a dead time. In one embodiment, the circuit arrangement includes a first input for applying the output voltage. A capacitive network includes a first and a second circuit node capacitively coupled to the input, and having a terminal for a reference potential. A recharging circuit during the switched-on phase of one of a first and second switching elements, adjusts electrical potentials of the first and second nodes, the electrical potentials each being different from the reference potential. A comparator arrangement, during the dead time, determines a time difference between such times at which the electrical potentials at the first and second node each assume a given potential value, the time difference being a measure for the change with time of the output voltage.

  • Patent number: 8890512
    Abstract: A device for visually indicating a change in the operational state of a proximity sensor. The device includes a transparent housing having a cavity and a magnet device for generating a magnetic field. In addition, a sleeve is attached to the housing. The magnet device is concealed within the sleeve in a first position to indicate a first operational state. When a target is positioned adjacent the sensor end, magnetic attraction occurs between the target and the magnet device due to the magnetic field to cause movement of the magnet device to a second position within the cavity wherein the magnetic field does not act on the proximity sensor to change the operational state from the first operational state to a second operational state. Further, the magnet device is visible in the second position to indicate the second operational state.
