    摘要： System and method for determining occupancy of a vehicle in which a radar system emits radio waves into an interior of the vehicle in which objects might be situated and receives radio waves and a processor coupled to the radar system determines the presence of any repetitive motions indicative of a living occupant in the vehicle based on the received radio waves such that the presence of living occupants in the vehicle is ascertainable upon the determination of the presence of repetitive motions indicative of a living occupant. Repetitive motions indicative of a living occupant may be a heart beat or breathing as reflected by movement of the chest. The processor may be programmed to analyze the frequency of the repetitive motions based on the received radio waves whereby a frequency in a predetermined range is indicative of a heartbeat or breathing.

    摘要： Methods for controlling a vehicle system in which radiation is directed from a transducer into the passenger compartment and is reflected off or modified by an object in the passenger compartment and received by the same or a different transducer. When ultrasonic waves are used, one or more techniques are used to compensate for thermal gradients in the passenger compartment and/or enable the use of a single transducer to send and receive waves, for example, a tubular mounting structure for the transducers, electronic reduction of ringing of the transducer, mechanical damping of the transducer cone, shaped horns, grills and reflectors for the output of the transducers to precisely control the beam pattern, a logarithmic compression amplifier, a temperature compensation method based on change in transducer properties with temperature and/or a dual level network, one level for categorization and the second for occupant position sensing.

    摘要： System and method for preventing vehicle accidents in which the absolute position of the vehicle is determined, e.g., using a satellite-based positioning system such as GPS, and the location of the vehicle relative to the edges of the roadway is then determined based on the absolute position of the vehicle and stored data relating to edges of roadways on which the vehicle may travel. A system or component within the vehicle is initiated, e.g., an alarm or warning system, or the operation of a system or component is affected, e.g., an automatic guidance system, if the location of the vehicle approaches close to an edge of the roadway or intersects with an edge of the roadway.

    摘要： A resistor array formed by the process of forming a plurality of holes or grooves in an electrically insulating substrate, filling the holes or grooves completely with a flowable, electrical resistance material, and then hardening the resistance material. The resistance material can be comprised of an electrically non-conductive thermally setting base material throughout which electrically conductive particles are dispersed, or the resistance material can be colloidal or a suspension. The value of the resistors is determined by the volume resistance of the resistance material and the volume of the holes or grooves, the resistance increasing as the length of the holes or grooves increases and decreasing as the cross-sectional area of the holes or grooves increases. A resistor array having leadless terminals is provided by sandwiching the insulating substrate between layers of electrically conductive material and forming the holes or grooves through at least one of the layers of electrically conductive material and the substrate, and then filling the holes or grooves with the resistance material.
