  • Publication number: 20200185259
    Abstract: A semiconductor reaction device and a semiconductor reaction method are disclosed. The semiconductor reaction device includes a vacuum chamber, a stage unit, a heating unit, and a first lifting mechanism. The stage unit carries a substrate. When the stage unit drives the substrate to rise, the substrate separates the vacuum chamber to form a reaction space and a bottom space. The heating unit is disposed in the vacuum chamber. The heating unit and the substrate are located on opposite sides of the stage unit. The first lifting mechanism connects with the heating unit so as to move the heating unit, so that the heating unit is movable relative to the stage unit. When the substrate rises to form the reaction space, the distance between the heating unit and the substrate is changed by the first lifting mechanism, thereby changing the temperature of the substrate.

  • Publication number: 20140362751
    Abstract: Disclosure herein is related to a portable voice routing apparatus, a system, and a method for processing a telephony voice call. In an exemplary embodiment of the invention, the portable voice routing apparatus provides a local network protocol service for the local-end terminal devices, and renders a connection bridging a mobile communication network. When the terminal device initiates a telephony voice communication procedure, the portable voice routing apparatus transmits the voice packets carried with subscriber identity information. Therefore the terminal device may establish a voice communication with a recipient over PSTN or network. At the recipient, a message with an incoming call is shown due to the received subscriber identity information. The recipient may therefore call back for bi-directional voice communication according to this message.

  • Patent number: 8452057
    Abstract: A method controls a projection of a projector. The method predetermines hand gestures, and assigns an operation function of an input device to each of the predetermined hand gestures. When an electronic file is projected onto a screen, the projector receives an image of a speaker captured by an image-capturing device connected to the projector. The projector identifies whether a hand gesture of the speaker matches one of the predetermined hand gestures. If the hand gesture matches one of the hand gestures, the projector may execute a corresponding assigned operation function.
