  • Patent number: 11605482
    Abstract: In an embodiment a thermal varistor protection device includes a casing, a varistor embedded in the casing, wherein the varistor includes a first metallization electrode, which is only partly covered by an insulating material of the casing to allow an electrically conductive connection, a first terminal wire electrically conductively connected to the first metallization electrode of the varistor and a contact element electrically conductively connected to the first metallization electrode of the varistor in a region where the varistor is not covered by the insulating material, wherein the contact element is pre-stressed to ensure a fast separation of the contact element and the first metallization electrode when the electrically conductive connection between the contact element and the first metallization electrode becomes loose.

  • Patent number: 11443876
    Abstract: A varistor component and a method for securing a varistor component are disclosed. In an embodiment a varistor component includes a first external contact, a second external contact, a varistor electrically connected to the first external contact, a path between the varistor and the second external contact and an active releasing device having a shutter and a heat sensitive element, wherein, under abnormal operation conditions, the heat sensitive element releases the shutter, and the shutter moves along a straight line and closes the path between the varistor and the second external contact.

  • Publication number: 20090174682
    Abstract: An instrumentation assembly for installation in a vehicle dashboard is disclosed herein. The instrumentation assembly includes an electronic controller, an enclosure, a viewable gauge, a viewable display, and a proximity-sensing switch. The controller has a memory for storing information. The enclosure has a designated front section and a designated rear section, wherein the front section includes substantially transparent material so as to define a window. Both the gauge and the display are electrically connected to the controller and mounted within the enclosure so as to substantially face the window. The switch is electrically connected to the controller and operable to sense the proximal presence of a human finger. In this configuration, the display is operable to exhibit the memory's information for viewing, and the switch is activatable by a human finger to selectively control the exhibition of the information on the display. Furthermore, an instrumentation module is also disclosed herein.

  • Patent number: 6826488
    Abstract: The present invention relates to a data storage medium encoded with the structural coordinates of crystallized molecules and molecular complexes which comprise the active site binding pockets of bacterial IMPDH. Such data storage material is capable of displaying such molecules and molecular complexes, or their structural homologues, as a graphical three-dimensional representation on a computer screen. This invention also relates to methods of using the structure coordinates to solve the structure of homologous proteins or protein complexes. In addition, this invention relates to methods of using the structure coordinates to screen and design compounds, including inhibitory compounds, that bind to IMPDH or homologues thereof. This invention also relates to molecules and molecular complexes that comprise the active site binding pockets of IMPDH or close structural homologues of the active site binding pockets.
