摘要： 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.

摘要： A capacitive sensing system for being connected to a heating element comprises a capacitive detector connectable to the heating element and a common mode choke for essentially preventing alternating current from flowing from the heating element to the heating current supply. The capacitive detector is configured for driving an alternating current into the heating element and for producing an output indicative of capacitance based upon the alternating current. The choke has a first and a second winding for connecting the heating element with the heating current supply. The choke comprises a third winding connected in parallel of the first and/or second winding. The capacitive detector is configured for measuring a portion of the alternating current flowing across the third winding and for taking into account the measured portion of alternating current when producing the output.

摘要： An occupant detection system and method that uses an isolation assembly to isolate electrically a power supply providing power to a heater element for heating a vehicle seat from a sensing circuit that uses the heater element as an electrode for electric field or capacitance type occupant detection. The isolation assembly includes a common mode choke that by itself provides sufficient isolation when the sensing circuit excitation signal frequency is high enough, and provides switches that infrequently interrupt electrical power to the heater element so a humidity level can be determined using a relatively low excitation signal frequency. Knowing the humidity level is desirable to adjust a threshold use to determine if the sensing circuit indicates that the seat is empty, or is occupied.

摘要： Various techniques are disclosed for systems and methods using small form factor infrared imaging modules to monitor occupants in an interior compartment of a vehicle. For example, a vehicle-mounted system may include one or more infrared imaging modules, a processor, a memory, alarm sirens, and a communication module. The vehicle-mounted system may be mounted on, installed in, or otherwise integrated into a vehicle that has an interior compartment. The infrared imaging modules may be configured to capture thermal images of desired portions of the interior compartments. Various thermal image processing and analytics may be performed on the captured thermal images to determine the presence and various attributes of one or more occupants. Based on the determination of the presence and various attributes, occupant detection information and/or control signals may be generated. Occupant detection information may be used to perform various monitoring operations, and control signals may adjust various vehicle components.
