  • Publication number: 20180038741
    Abstract: An internal combustion motor vehicle temperature sensor. The sensor comprises a metal mounting port having a threaded portion, an electrical terminal, a temperature sensing element electrically connected to the electrical terminal and enclosed within a cavity defined by the metal mounting port, and a plastic connector molded over the metal mounting port, where the plastic encases at least a portion of the electrical terminal and where the plastic connector defines a torque transfer shoulder.

  • Patent number: 8523432
    Abstract: A temperature sensor includes a polymer body for mounting the sensor to a mounting surface and positioning a temperature sensing element within a target fluid. The temperature sensing element may be positioned at the distal end of the polymer body and may be sealed from the fluid by a metal cap filled with a thermally conductive material. In this manner, the polymer body may thermally insulate the temperature sensing element and lead conductors within the polymer body from the mounting surface. The polymer body may also include a connector on the proximal end to facilitate an electrical connection with the temperature sensing element, a flange to install the sensor against the mounting surface, and a fixation surface configured to mate with the mounting surface. In some examples, the polymer body may be constructed in two stages to facilitate different configurations of the connector, flange, and/or fixation surface.

  • Publication number: 20120229937
    Abstract: A system includes a control switch and a control module. The control switch is configured to drive current through an electrical load in a closed state, and disconnect the electrical load from a power supply in an open state. The control module is configured to connect to a thermostat switch that operates in one of an open state or a closed state based on a temperature of the thermostat switch. The control module is further configured to control a state of the control switch based on a state of the thermostat switch and detect a fault in the control switch based on the state of the thermostat switch and a voltage across the control switch.

  • Patent number: 7458718
    Abstract: A temperature sensor and method of forming the same includes a temperature sensing portion having a metal housing configured with at least one circular fin on a surface of the metal housing. A temperature sensing element is generally associated with the temperature sensing portion, wherein a potting is located within a gap formed between the temperature sensing element and the metal housing and joined with a ceramic tube for carrying a plurality of high temperature metal lead wires to and from the temperature sensing portion, thereby forming a temperature sensor utilized in an exhaust gas environment to measure temperature and improve a response time and accuracy of the temperature sensor due to an increase in surface area of the sensor tip for a given thermal mass for convection heat transfer.

  • Patent number: 7360947
    Abstract: An apparatus for temperature sensing is disclosed that includes a sensor tube and a cable assembly connected to and extending from said sensor tube wherein said cable assembly communicates electrically with the sensor tube for temperature sensing operations thereof. An O-ring component can be selected based on an inner diameter of said sensor tube and an outer diameter of said cable assembly, wherein said o-ring component is crimped in order to seal and protect said sensor tube from de-alignment and misplacement and located co-axial to said sensor tube and said cable assembly, thereby providing an enhanced mechanical strength and prevention against leakage or ingress of moisture from or to said sensor tube.

  • Patent number: 6813501
    Abstract: A system for providing location dependent services to a plurality of mobile terminals within a coverage area. The system defines services deployment areas in which the services are available. A server receives, from a plurality of sources, location information indicating the locations of mobile terminals and tracks them so that their presence in particular service deployment areas can be determined. The services receive meta-information classifying the location information and use this meta-information to determine whether the source of the location information is reliable enough for the service to be provided. If it is reliable enough, the service is provided to the mobile terminal.
