An anti-entrapment system for preventing an object from being entrapped by a translating device such as a vehicle window includes a capacitance sensor and a controller. The sensor has a jacket with a cavity, a dielectric element within the cavity, and first and second electrical conductors. The conductors are within the cavity on opposite sides of the dielectric element such that the conductors are separated from one another by a separation distance. The capacitance of the sensor changes in response to an electrically conductive object moving in proximity to at least one of the conductors. The controller is configured to control a translating device as a function of the capacitance of the sensor. The jacket is attachable to a seal configured to receive the translating device.

Anti-entrapment system

Disclosed is an improved system and method for sensing both hard and soft obstructions for a movable panel such as a sunroof. A dual detection scheme is employing that includes an optical sensing as the primary means and electronic sensing of motor current as a secondary means. The secondary means utilizes system empirical precharacterization, fast processing algorithms, motor parameter monitoring including both current sensing and sensorless electronic motor current commutation pulse sensing, and controller memory, to adaptively modify electronic obstacle detection thresholds in real time without the use of templates and cycle averaging techniques.

Monitoring system

An inline tool tracking system for tracking an inline tool traveling along a pipe includes a detection and communication device operable to detect an inline tool as it passes generally near the device. The detection and communication device is operable to generate a detection output, which includes data indicative of the detection of the tool and a geographical location of the device. A control is operable to wirelessly receive the detection output and to process the detection output. The control generates a control output responsive to the processing, and the control output is indicative of the detection of the tool and the geographical location of the detection and communication device. A display device receives an input indicative of the control output and displays the information indicative of the detection of the tool and the geographical location of the detection and communication device to a user of the display device.

Collision monitoring system

An anti-entrapment system for preventing an object from being entrapped by a translating device includes a sensor positionable adjacent to or on the translating device. The sensor has a non-conductive compressible jacket with a cavity, and first and second conductors positioned within the cavity opposite from one another. In response to an object pressing against the jacket, the jacket compresses from a non-compressed state in which the conductors are not in electrical contact to a compressed state in which the conductors are in electrical contact. The sensor has a compressible support either inside or outside of the cavity. In response to the object pressing against the jacket while the jacket is compressed, the support compresses to allow the jacket to compress further in order reduce pinching of the object by the translating device when the object is between the jacket and the translating device.

An anti-entrapment system for preventing objects from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device and a controller. The sensor has first and second conductors separated by a separation distance and a compressible dielectric element interposed between the conductors. The conductors have a capacitance dependent upon the separation distance. The capacitance of the conductors changes in response to a geometry of the sensor changing as a result of either conductor or the dielectric element deforming in response to a first object touching the sensor. The capacitance of the conductors changes in response to a second conductive object coming into proximity with either conductor. The controller receives a signal from the sensor indicative of the capacitance of the conductors, and controls the translating device as a function of the capacitance of the conductors to prevent the translating device from entrapping either object.

Electronic control for a hydraulic system driving an auxiliary power source is provided, with specific application as a system for controlling the operation of a hydraulically driven AC generator. The system may includes a hydraulic pump, a hydraulic motor drivably connected to the generator, a fluid circuit for circulating fluid from the pump to the motor and back. The fluid circuit may contain a bypass conduit to bypass the motor. The system also includes a proportional servo control valve assembly for controlling the fluid circuits and a control circuit for controlling the proportional control valve assembly. The control system can be capable of controlling the flow of hydraulic fluid to the motor powering the electrical or mechanical system. Sensors for measuring the operating parameters of the system and an operator interface module can influence the operation of the system.

An integrated fuel management system and method for controlling the fuel storage and delivery in a vehicle. The fuel management system includes a fuel storage tank for storing fuel in a vehicle, a vapor collection canister located within the fuel storage tank, a vent actuator coupled to the vapor collection canister for venting gas from the canister during a vent operation, and a purge actuator is coupled to the vapor collection canister for purging fuel vapor from the vapor collection canister during a purge operation. A variable speed fuel pump is disposed within the fuel storage tank for delivering fuel to a fuel delivery line for an engine. The fuel management system has a controller provided in a module disposed in communication with the fuel for controlling the amount of fuel pumped with the variable speed fuel pump to deliver fuel to the fuel delivery line and further controlling the purge and vent actuators.

Vehicle fuel management system

An anti-entrapment system for preventing an object from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device. The sensor has first and second conductors separated by a separation distance, a compressible dielectric element interposed between the conductors, and a non-conductive elastomer outer jacket encasing the conductors and the dielectric element. The sensor having a capacitance dependent upon the separation distance between the conductors. The capacitance changes in response to the separation distance changing as a result of the dielectric element compressing in response to a first object touching the outer jacket, and in response to a second conductive object coming into proximity with at least one of the conductors. A controller controls the translating device as a function of the capacitance in order to prevent the translating device from entrapping either object.
