    摘要: The present invention provides a method and apparatus for recording vehicle motion. The self-contained vehicle motion recorder apparatus is a sealed unit that contains at least a power source, and controller, sensor and recording devices. The controller device includes a power consumption manager that manages and conserves the overall power consumption of the apparatus. A sensor device is further included in operable communication with the controller device that produces signals that represent the vehicle's motion as a function of time. Additionally, a recording element is provided in operable communication with the controller for storing data that corresponds to the signals. A communication interface is further provided such that data may be read from the apparatus and commands and data may be written into the apparatus, from an external device.

    摘要: The method for mapping a mechanical property of a surface of a sample with a scanning force microscope comprises the steps of (a) scanning a fine tip in contact with the surface of the sample within a predetermined scan area, the fine tip being supported on an end of a cantilever beam, (b) applying a loading force on the surface of the sample by the fine tip, (c) using a constant frequency sine wave to oscillate the cantilever beam relative to the surface of the sample, (d) measuring a detector response of the fine tip at the end of the cantilever beam, (e) determining an amplitude of the detector response and a change in phase angle of the detector response relative to the sine wave used to oscillate the cantilever beam, and (f) relating the amplitude and the change in phase angle to a property of the surface of the sample. A feedback system is utilized which regulates the total force imposed by the fine tip onto the surface of the sample so that the amplitude of the detector response is maintained constant. Because the force does not depend on the topography of the sample, the average cantilever deflection is directly related to the mechanical property of the surface of the sample and is not affected by any topographical feature present on the surface of the sample.

    摘要: The present invention provides a method and apparatus for recording motion of a vehicle or a fixed structure with a self-contained motion recorder apparatus. The self-contained motion recorder apparatus is a sealed unit that contains a power source together with controller, sensor and recording devices. The controller device includes a power consumption manager that manages and conserves the overall power consumption of the apparatus. A sensor device is further included in operable communication with the controller device that produces signals that represent the motion of the vehicle or structure as a function of time. Additionally, a recording element is provided in operable communication with the controller for storing data that corresponds to the signals. A communication interface is further provided such that data may be read from the apparatus and commands and data may be written into the apparatus, from an external device.
