  • Patent number: 11962252
    Abstract: An apparatus to insure safe behavior in an inverter system. In one embodiment, the apparatus includes a first high side gate driver, a first low side gate driver, a microcontroller configured to control the first high side and low side gate drivers. A voltage regulator provides a supply voltage to the microcontroller. A first pair of high side voltage regulators provide a first pair of high side supply voltages to the first high side gate driver. A first pair of low side voltage regulators provide a first pair of low side supply voltages to the first low side gate driver.

  • Patent number: 9797786
    Abstract: The invention relates to a device (100) for calibrating the temperature of a fiber-optic temperature sensor, with which an optical fiber (10) of a fiber-optic temperature sensor is to be provided. The device (100) comprises a device body (101) having a passage (109) through which the optical fiber (10) is to pass, and a means for transferring heat energy. The device (100) further comprises at least one portion (160a), referred to as a first fixed point, which is made from a first material having at least a first predefined temperature at which the state thereof changes. The first fixed point (160a) is thermally connected to the optical fiber (10) when the optical fiber (10) is provided with the device (100). The heat-transferring means is arranged in the device body (101) such that, during the actuation thereof, the heat-transferring means exchanges heat energy with the first fixed point (160a) so as to cause a change in the state thereof at the first predefined temperature.

  • Patent number: 6939034
    Abstract: The mechanism for transmission of axial and rotative movements between two portions of a stem with offset axes, includes a movable assembly movable axially. The section portion of the stem carries a second pinion and is pivoted on said movable assembly but it is axially secured to, this movable assembly. The first portion of the stem is pivoted on the movable assembly but axially secured to this latter and is secured to a first pinion, one or an uneven number of reverser(s), pivoted on the movable assembly kinematically connects the first pinion to the second pinion.
