  • Patent number: 8533969
    Abstract: An apparatus includes a base, a cover and a rotating shaft. The base includes a platform formed on the base for placing a workpiece, a supporting post protruding from the platform, and a pair of opposite connecting seats protruding from an end of the base. Each connecting seat defines a pin hole. The cover includes a board portion defining a positioning hole corresponding to the supporting post, a hollow rotating portion defining a through hole, and a connecting portion interconnecting the board portion and the rotating portion. The rotating shaft extends through the rotating portion with two ends received in the pin holes, rotatably interconnecting the cover to the base. The radius of the through hole is larger than that of the rotating shaft. When the board portion presses on the workpiece, the supporting post lifts the board portion.

  • Patent number: 8467978
    Abstract: A method and apparatus for inspecting a surface of an object. Data from measuring the surface of the object is obtained to form surface data for the object. A range of frequencies for features on the object is selected based on a range of distances between adjacent peaks for the features. The features are formed by a tool moving along a number of paths. Desired surface data for the features is obtained from the surface data using the range of frequencies selected. A determination is made as to whether the desired surface data for the features meets a policy specifying a desired surface for the object. In response to an absence of a determination that the desired surface data for the features meets the policy, the object is reworked.

  • Patent number: 8457926
    Abstract: The present invention relates to a disk protrusion detection/flatness measurement circuit and a disk glide tester, in which protrusion detection and average value calculation can be performed without switching signal processing circuits of two systems, one for the protrusion detection of a disk and the other for the average value calculation with respect to a track or a sector of the disk. This also makes it possible to reduce the size of the measurement circuit. In the protrusion detection/flatness measurement circuit, a signal from a protrusion detection sensor is amplified and converted from an analog signal to a digital signal. The signal passes through a band-pass filter to obtain a digital signal with a predetermined bandwidth. Then, peak detection and average value calculation processes are applied in parallel to the obtained digital signal. Thus, pass/fail decision of the disk can be made based on the detected peak and average values.

    Abstract: A testing device for testing whether planeness of top and bottom surfaces of an object is within an allowable range includes a rack, a motion mechanism, a transmission mechanism, a control mechanism, a testing mechanism, and a display. The motion mechanism is slidably connected to the rack and supporting the object. The transmission mechanism is fastened to the rack and the motion mechanism. The testing mechanism includes two separated rows of sensors. The object extends through the testing mechanism, between the rows of sensors. The sensors above the object measure distances between the sensors and corresponding dots of a top surface of the object. The sensors below the object measure distances between the sensors and corresponding dots of a bottom surface of the object. The sensors send signals about the distances to the control mechanism.

  • Patent number: 8417423
    Abstract: A defined vehicle path emulator system is described, which system can be used for measuring the F-min values and profiles for a path on a concrete floor traversed by a vehicle with a specific wheelbase. The defined vehicle path emulator is an autonomous robot that guides itself down the selected path. The F-min values are used to calculate the deviations away from zero planar infinity while traversing the path for a tall mast carried by an emulated vehicle. This invention's systems are distinct from the (FF/FL) floor flatness and floor levelness measuring systems in the literature as prior art. The floor can be marked for deviations from flatness by means of a laser etching system activated by the emulator's software system. The emulator can also signal an operator when it detects itself veering off of the defined path.
