  • Publication number: 20060261818
    Abstract: A robust, easily deployable, covert, passive intrusion detection system uses one or more E-field sensors to detect the presence of a moving individual and to provide an indication of the presence of the individual adjacent the sensor based on E-field distortion produced by the individual. Single-ended and differential E-field sensors with noise canceling and a guarding circuit provide sufficient sensitivity, with filtering from 0.5 Hz to 8.0 Hz selecting only human intruders. Either visible or invisible flashing light sources at the sensor indicate the presence of a moving individual at the sensor, thus to provide intruder location without the necessity of providing a geolocation system.

  • Publication number: 20060138374
    Abstract: A valve actuator assembly is disclosed. The assembly comprises a stator; an armature housing; and an adjustable spacer coupled between the stator and the armature housing, wherein the spacer yields at a controlled rate when an axial load is applied thereto. The adjustable spacer is positioned between the stator and the armature housing such that when an axial load is applied, the adjustable spacer compresses at a controlled rate, thereby allowing adjustment of the valve stroke. A system and method in accordance with the present invention is applicable to any valve which includes a housing containing a seat, an armature, a stator, and a mechanism that is capable of applying a load to the housing.

  • Publication number: 20050230494
    Abstract: A flow control valve for controlling the flow of fuel in a fuel system including a housing with a fuel passage, a valve device movable to close the fuel passage to block fuel flow through the fuel passage, and to open the fuel passage to permit fuel flow through the fuel passage, a valve plunger engaging the valve device, an actuator for reciprocally moving the valve plunger, an armature overtravel feature for permitting continued movement of the armature relative to the valve plunger from an engaged position into a disengaged position when the valve plunger reaches the extended position, and an armature stop for stopping overtravel of the armature.

  • Publication number: 20050028797
    Abstract: A preferred embodiment EGR valve permits exhaust gas to be induced into the intake line downstream of the compressor, while minimizing the need to reduce the size of the turbocharger. The preferred embodiment EGR valve exploits variations around the mean pressure in the EGR passage created by the engine cycle by selectively opening when the pressure in the EGR valve exceeds the pressure in the intake line. Thus, exhaust gas is recirculated even when the engine is running near torque peak. The preferred embodiment EGR valve also exploits the higher mean pressure in the exhaust line relative to the intake line at higher engine speeds by remaining open, in order to minimize the energy consumed in opening and closing the EGR valve.
