Patent number: 8582280Abstract: A foldable keyboard for a portable computer includes a keyboard body which comprises two keyboard pieces hinge-coupled by a hinge unit in order to be unfolded in a direction parallel to a keyboard plane. Another embodiment of the invention is a foldable keyboard, which includes: a guide unit at which a long hole is formed along its length; and a keyboard body which comprises two keyboard pieces hinge-coupled to the guide unit by a hinge unit. The keyboard pieces can be unfolded in a direction parallel to a keyboard plane into its extended state. As the keyboard pieces unfold, the hinge unit slides along the long hole as the keyboard edges, which are facing each other, are stuck together. Thus, the two keyboard pieces are hinge-coupled to each other to reverse their vertical and horizontal directions as the keyboard body is extended.Type: GrantFiled: January 9, 2009Date of Patent: November 12, 2013Inventor: Sang Kyu Ryu

Patent number: 8502774Abstract: To provide an input apparatus, a control apparatus, a control system, and a control method that are capable of restricting a movement of a pointer on a screen by a user operation even while the input apparatus is moving. In a state where a movement button is not pressed by a user, an MPU of an input apparatus is not outputting a movement command or is outputting a movement command with a displacement amount set to 0. In other words, even when the user holds the input apparatus and moves it, a pointer does not move on a screen. As a result, a movement of the pointer unintended by the user can be restricted. When the movement button is pressed, that is, when a first operation signal is input via a first switch, the MPU starts outputting the movement command. By receiving the movement command, an MPU of a control apparatus controls display of the pointer so as to start the movement of the pointer that corresponds to the movement command.Type: GrantFiled: August 8, 2008Date of Patent: August 6, 2013Assignee: Sony CorporationInventors: Kazuyuki Yamamoto, Hidetoshi Kabasawa, Kenji Hachisu, Hideaki Kumagai, Katsuhiko Yamada, Takashi Masuda, Kunihito Sawai

Patent number: 8502761Abstract: The invention relates to a transparent component (100) comprising active members (10) that are juxtaposed in parallel to a surface of the component, and that are each switchable between a transparent state and a reflecting state. Each active member establishes a light path between a light passage opening and a side of the component when said active member is reflecting. An addressing system (2) further controls the switching of the active members so that a reduced number of active members is simultaneously reflecting. Therefore, an image formed by transparency through the component thus appears permanently and continuously. Such a transparent component can be used for making an image superimposition device and an image display and storage device.Type: GrantFiled: January 8, 2009Date of Patent: August 6, 2013Assignee: Essilor InternationalInventors: Christian Bovet, Jean Paul Cano
