  • Publication number: 20070135984
    Abstract: Land-based vehicle including an arrangement for monitoring objects in or about a vehicle includes a source from which modulated illumination is emitted into an area in or about the vehicle, a receiver arranged to receive illumination reflected from an object in the path of the modulated illumination, and circuitry coupled to the receiver and the source and arranged to compare a phase of the modulated illumination with a phase of the reflected radiation at a common frequency to determine whether there is a phase difference between the modulated illumination and the reflected illumination. The phase difference is a measure of a property of the object, such as the distance between the object and the source/receiver, which can be co-located. Otherwise, if the source and receiver and not co-located or substantially co-located, the distance is a measure of the distance of travel of the illumination.

  • Publication number: 20070135982
    Abstract: Method for determining weight of an occupant of an automotive seat involves arranging a bladder having at least one chamber in a seat portion of the seat, measuring the pressure in each chamber and deriving the weight of the occupant based on the measured pressure. The pressure in each chamber may be measured by a respective transducer associated therewith. The weight distribution of the occupant, the center of gravity of the occupant and/or the position of the occupant can be determined based on the pressure measured by the transducer(s). In one embodiment, the bladder is arranged in a container and fluid flow between the bladder and the container is permitted and optionally regulated, for example, via an adjustable orifice between the bladder and the container.

  • Publication number: 20070114292
    Abstract: Method for controlling a HVAC system in a vehicular compartment includes monitoring temperature of an occupant in the compartment from a location apart from the occupant, and controlling the HVAC system based on the monitored temperature. Occupant temperature may be monitored by infrared sensors, each arranged in an orientation to receive electromagnetic radiation from one or more seating locations in which occupants are likely to be situated. The temperature in each seating location is independently monitored. The HVAC system is controllable for each seating location based on the monitored temperature in that area. When monitoring of temperature in an area in which a driver of the vehicle is likely to be situated indicates presence of the driver, and no other areas indicate presence of a human occupant, the HVAC system is controllable such that all heat or air-conditioning provided by the HVAC system is directed to the driver.

  • Publication number: 20060251293
    Abstract: System and method for detecting the presence of contents of a vehicular compartment in which a detector system generates an output signal indicative of the absence of an object in the compartment when an object is not situated in the compartment and a different output signal indicative of a particular object in the compartment when such an object is situated in the compartment. Different output signals are thus generated for different objects. A processor is coupled to the detector system for processing the output signal to create a signal characteristic of the object which is indicative of whether the object is animate or inanimate. This system is coupled to a reactive system for affecting one or more vehicular components when the created signal is indicative of an animate object. The reactive system may be a release device for opening an access door or panel to the compartment.

    Abstract: System for obtaining information about a vehicle or a component therein includes sensors arranged to generate and transmit a signal upon receipt and detection of a radio frequency (RF) signal and a multi-element, switchable directional antenna array. Each antenna element is directed toward a respective sensor and transmitter RF signals toward that sensor and receive return signals therefrom. A control mechanism controls transmission of the RF signals from the antenna elements, e.g., causes the antenna elements to be alternately switched on in order to sequentially transmit the RF signals and receive the return signals from the sensors or cause the antenna elements to transmit the RF signals simultaneously and space the return signals from the sensors via a delay line in circuitry from each antenna element such that each return signal is spaced in time in a known manner without requiring switching of the antenna elements.
