  • Publication number: 20140098218
    Abstract: A moving control device is provided, including a filtering element, an image capturing unit, a calculating unit, and a light-emitting element that emits a structured light with a predetermined wavelength. The filtering element allows the structured light to pass therethrough while filtering out without the predetermined wavelength. The filtering element is provided in a portion at a front end of the image capturing unit, such that an external image retrieved by the image capturing unit includes a first region generated as a result of the light intersecting the filtering element and a second region generated as a result of the light not intersecting the filtering element. The calculating unit performs image recognition on the first and second regions of the external image to generate identification results to allow controlling movement of an autonomous mobile platform based on the identification results.

  • Patent number: 8555171
    Abstract: A portable virtual input control device and a method thereof are provided, which can achieve a purpose of human-machine interaction and remote control. The portable virtual input control device comprises a main body, an operation interface display unit connected to the main body, an image capturing module adjacent to the main body, and a central processing module, built in the main body. The operation interface display unit is movably disposed in front of a head of the user for displaying an operation interface corresponding to a controlled device. The image capturing module captures a position image of a hand of the user outside the operation interface display unit.

  • Publication number: 20050082945
    Abstract: A load-adjustable SAW (Surface Acoustic Wave) actuator arrangement includes a platform having two sliding bearings symmetrically disposed at two sides; a SAW actuator disposed in the platform between the sliding bearings for producing a surface acoustic wave at the top surface thereof, a slider disposed inside the platform and movable by the SAW actuator along the sliding bearings, and a support structure. The slider has a pressure bearing structure disposed in contact with the top surface of the SAW actuator and two positioning portions respectively supported on the sliding bearings. The support structure applies a predetermined force to the slider subject to the load carried on the slider, keeping the contact pressure between the slider and the SAW actuator about a constant value.
