  • Publication number: 20130278563
    Abstract: An optical touch device includes an indication plane, two image sensing units and a processing unit. The two image sensing units are disposed at two corners of the indication plane diagonal to each other, respectively, and the two corners define a diagonal line connected therebetween. The processing unit is electrically connected to the two image sensing units. When two touch points are performed on the indication plane, the processing unit determines whether the two touch points are located at opposite sides of the diagonal line, respectively, according to images sensed by the two image sensing units. Once the two touch points are located at opposite sides of the diagonal line, respectively, the processing unit calculates and outputs coordinates of the two touch points immediately according to the images sensed by the two image sensing units.

  • Patent number: 8549274
    Abstract: A distributive cache accessing device for accelerating booting remote diskless computers mounted in a diskless computer equipped with WAN-bootable hardware, such as an iSCSI host bus adapter (HBA), allows to access data required to boot the diskless computers or run application programs thereon from an iSCSI target or other diskless computers having the distributive cache accessing device via a network. The retrieved iSCSI data blocks are temporarily stored in the local distributive cache accessing device. If any other diskless computer requests for the iSCSI data blocks, the temporarily stored iSCSI data blocks can be accessible to the diskless computer. Given installation of a large number of diskless computers, the network traffic of the iSCSI target is alleviated, and booting remote diskless computer is accelerated.

    Abstract: A frameless optical touch device includes an indication plane, an image sensing unit, a light emitting unit and a processing unit. There is no any frame disposed on a periphery of the indication plane such that a first light from an external environment can enter a sensing region defined on the indication plane through the periphery of the indication plane. The light emitting unit emits a second light to the sensing region. When there is no any touch object in the sensing region, the image sensing unit senses the first and second lights to generate a first image. When a touch object is in the sensing region, the image sensing unit senses the first and second lights to generate a second image. The processing unit compares brightness of the first image with brightness of the second image so as to obtain a position blocked by the touch object.
