| 20110240896 | Three-Port Valve - A three-port valve includes a valve body including a first port, a second port, and a third port, the first port having a first valve orifice and the second port having a second valve orifice. The valve may also include a first valve closure member and a second valve closure member, the first and second valve closure members may be configured to selectively seal the first and second valve orifices, respectively. The valve may further include a solenoid including a first coil and a second coil, at least one of the first and second coils configured to actuate at least one of the first and second valve closure members when energized. Additionally, the valve may include an electrical connection configured to selectively and individually energize the first and second coils. The valve may be configured to operate in at least three different states of operation. For example, the three-port valve may have a first state (e.g., a default state) when neither coil is energized, a second state when first coil is energized to move only one of the valve closure members, and a third state when the second coil is energized to move both valve closure members. | 10-06-2011 |
| 20110238281 | Exhaust Gas Temperature Sensor Including Strain Relief and/or Anti-Vibration Sleeve - A temperature sensor includes a housing and a temperature sensing element disposed in the housing. Electrical connections may extend from the temperature sensing element through the housing and an epoxy may be disposed in the housing, wherein the epoxy may at least partially around the temperature sensing element. The epoxy may provide a thermal pathway between the sensing element and the housing and may be being flexible to accommodate different rates of thermal expansion between the temperature sensing element and the electrical connections without requiring a separate mechanical strain relief. A temperature sensor system includes a temperature sensor and a mineral insulated cable coupled to the temperature sensor. The temperature sensor may be configured to be removably coupled to the mineral insulated cable via a stop flange and a sleeve coupled to the mineral insulated cable. The sleeve may be configured to provide stability and reduce vibrational stress to the temperature sensor system. | 09-29-2011 |
| 20110203457 | Filtration Device for use with a Fuel Vapor Recovery System - A filtration device | 08-25-2011 |
| 20110203348 | SOOT SENSOR SYSTEM - A soot sensor includes a soot sensor including a sensor element and heater element disposed on a first surface of the soot sensor. A soot sensing system may include a soot sensor and circuitry electrically coupled to the sensor and heater elements of the soot sensor. The circuitry is configured to determine an amount of soot accumulated on the soot sensor and to control heating of the heater element in response to the soot accumulation. | 08-25-2011 |
| 20100258329 | Sensor Lead Sealing and Strain Relief - A sensor system may comprise a wiring harness comprising at least one wire, a grommet, a nugget, a sensor, and a harness sleeve. The grommet may comprise at least one passageway configured to receive the wire. The nugget may comprise at least one terminal molded into the nugget and coupled to the wire. A mineral insulated cable may be coupled to the sensor and to the terminal. The harness sleeve may define at least one cavity configured to receive the nugget and at least a portion of the grommet. The harness sleeve may be coupled to the mineral insulated cable and may include a first crimp coupling the harness sleeve to the grommet. The exterior surface of the nugget may also include at least one radially disposed groove. The harness sleeve may also include a second crimp coupling the harness sleeve to the nugget, for example, about the radial groove. The first crimp may be configured to compress the grommet to provide a seal between the harness sleeve and the grommet and a seal between the grommet and the at least one wire of the harness wire. The second crimp and the molding of the terminal within the nugget may be configured to provide strain relief for the wiring harness. | 10-14-2010 |
| 20090151859 | Temperature Sensor - A temperature sensor including a housing and a temperature sensing element at least partially disposed in the housing. A particulate media, which may include a blend of differently sized particles, is disposed in the housing and at least partially surrounds the temperature sensing element. The particulate media may entrain oxygen to avoid a reducing atmosphere in said housing. | 06-18-2009 |
| 20090025693 | Filtration Device for Use with a Fuel Vapor Recovery System - A filtration device for filtering air for use with a fuel vapor recovery system. According to one aspect, the device includes a housing defining a chamber having a rotational axis an upper end and a lower end, a cap closes the housing and includes at least one generally helical passageway helically extending generally toward the lower end of the chamber and includes at least one air inlet. According to another aspect, the device includes a non-circular filter element disposed between an air inlet and an air outlet. | 01-29-2009 |
| 20090008823 | Sealed Sensor Assembly and Method of Making the Same - A method of sealing a sensor assembly from contaminants including inserting the assembly into an overmold, providing a first stage overmold to cover a first portion of said sensor assembly intended to be external to an associated bore, and providing a second stage overmold to cover a second portion of the assembly intended to be disposed in the associated bore. | 01-08-2009 |
