  • Patent number: 9423246
    Abstract: A three-dimensional measurement system includes a measurement platform, a projection module, an image-capturing module, and a control unit. The measurement platform carries a test object. The projection module includes a light-emitting unit, a light-shielding rotary disc, a grating unit, and an optical-reflective ring structure. The light-emitting unit generates a light beam. An aperture formed in the light-shielding rotary disc is located at different rotational positions time-sequentially while the light-shielding rotary disc rotates, and the light beam passes through the aperture to form light beam segments. The grating unit transforms the light beam segments into stripe-patterned structure-light beams. The optical-reflective ring structure reflects the stripe-patterned structure-light beams onto the test object. The image-capturing module captures stripe-patterned images formed after reflection of the stripe-patterned structure-light beams from the test object.

  • Publication number: 20130278723
    Abstract: A three-dimensional measurement system includes a measurement carrier, first and second projection modules, an image-capturing module, and a control unit. The measurement carrier carries a test object on a measurement plane. The first projection module projects a first patterned structure light onto the test object along a first optical axis that forms a first incident angle relative to the measurement plane, and the second projection module projects a second patterned structure light onto the test object along a second optical axis that forms a second incident angle different from the first incident angle. The image-capturing module captures first and second patterned images formed after reflection of the first and second patterned structure lights from the test object. The control unit controls the first and second projection modules, and measures a three-dimensional shape of the test object according to the first and second patterned images.

  • Patent number: 5831856
    Abstract: A dynamic random access memory (DRAM) testing apparatus includes a substantially upright support plate on which at least one elongated feeding chute is provided, having a channel co-extensive therewith for receiving and holding therein an IC bar which contains a number of DRAMs to be tested. The DRAMs are movable downward along the channel by means of gravity. A shifting mechanism, which is controlled by a control unit, sequentially transfers the DRAMs from the feeding chute to a testing device defining a holder for receiving the DRAM to carry out the test. The test is conducted by the control unit and the test result is transmitted thereto for classifying the DRAM being tested. The tested DRAM is then forwarded to a movable member to be conveyed thereby to a particular one of a plurality of out-feeding chutes which are associated with different classifications of the DRAMs. The DRAM is then moved from the out-feeding chute to an empty IC bars to be collected therein.

  • Patent number: 5329411
    Abstract: A cassette loading mechanism comprising a movable plate-like member which is maintained on the same plane with a stationary plate-like member and slidable relative to the stationary member. A symmetrical four bar linkage is connected between the two members. The movable member is moved, under the guidance of fixed shaped slots, with a cassette holder into which a cassette is inserted between an unloading position and a loading position by an actuation device acting at one side of the cassette holder. The four bar linkage transmits the actuation to the other side of the cassette holder in a substantially synchronous way to make both sides of the cassette holder move symmetrically and synchronously and thus reducing the risk of jamming.
