    摘要: Systems and methods are disclosed for improving the resolution and quality of an image formed by signals from an array of receivers. Multiple receivers introduce variations in arrival times that can be less than the period of an operating signal, and also less than the period associated with a sampling operation. Thus, multiple receivers allow sampling of fine features of reflected signals that would be considered beyond the resolution associated with the operating signal. Use of multiple receivers also provides an effective sampling rate that is greater than the sampling rate of an individual receiver. Similar advantages can be obtained using multiple transmitters. Such advantageous features can be used to obtain high resolution images of objects in a medium in applications such as ultrasound imaging. Sub-Nyquist sampling is discussed. Accounting for the effects of refraction on pathlengths as a signal passes between two regions of different sound speed allows improved calculation of focus distances. Extending the analysis to account for additional layers or sub-layers allows further improvement.

    摘要: A method and system for detecting the presence of an object caught between an automotive window and its respective frame includes an electric drive motor for opening and closing the automotive window. The electric drive motor receives power from a power supply via a primary brush assembly coupled to a power line. A piezoelectric sensor is mounted on the drive motor for sensing a resistive torque applied to the regulator and generating a signal having a value indicative of the resistive torque. The signal is then transmitted to a control circuit for determining whether or not an object is caught between the window and a frame based on the signal. The signal may be transmitted to the control circuit either by the primary brush assembly via the power line or by a secondary brush assembly coupled directly to the control circuit.

    摘要: An active window seal assembly is disclosed that operatively engages a movable window when the window is stationary and disengages the window when the window is in motion. The seal assembly comprises a stationary frame, a movable lip that is operatively connected to the stationary frame, and a cavity disposed between the stationary frame and the movable lip. Several configurations provide for movement of the movable lip when the movable window is in motion. The first configuration allows the cavity to inflate with air, thus forcing the movable lip away from the window. A second configuration provides that the air in the cavity be evacuated, thus pulling the movable lip away from the window. A third configuration provides that a voltage be applied to the stationary frame and the movable lip to create an electric field. The electric field draws the movable lip toward the stationary frame and away from the movable window.

    摘要: An object detection system includes a sensor in communication with a controller which identifies contact with the sensor. In a preferred embodiment the sensor is a piezo film which generates a signal when an object applies a predetermined force to the edge of the moveable glass member. This signal is identifiable by the controller in communication with the piezo film. Another embodiment of the sensor provides a pair of substantially parallel segments of conductive material applied along the edge of the window. When an object is in contact with both segments of conductive material an electrical signal is conducted and identified by the controller. When the controller determines an object is in contact with the sensor and therefore the moveable glass member, the controller halts or reverses the movement of the moveable glass member to prevent trapping the object between the closing moveable glass member and the frame.

    摘要: In a first embodiment, a vehicle window obstruction system incorporates a conductive coating placed on the window. Such coatings are known for use in defrost systems. A voltage source is connected to the conductive coating, such that an electrical charge is placed across the window. Electrical characteristics of the charge are monitored, and compared to expected values. In the event that an obstruction is encountered, the monitored values will differ from expected values, and a control can indicate the presence of an obstruction. Alternatively, the signal could be a high frequency signal such as a sound signal which would be varied when the window contacts a human obstruction.
