Abstract: A head-mounted display (HMD) may include a sensor unit, a display unit configured to display an image, and a control unit for measuring a tapping applied to the head-mounted display from a measurement value obtained by the sensor unit, and controlling the image displayed on the display unit by using the tapping as an input signal. When the HMD is used, an image displayed on the HMD may be controlled by using a tapping applied to the HMD as an input signal, and thus, an event may be processed without using any additional controller.

Abstract: The exemplary embodiments of this invention generally relate to message header-type notification that, for example, enables the co-existence of a legacy header type with one or more new header types on a same radio link. In one non-limiting, exemplary embodiment, a method includes: determining a type of medium access control (MAC) header to transmit in a MAC transmission; setting a value of a notification field in a resource allocation message based on the determined type of MAC header; and transmitting the resource allocation message. In another non-limiting, exemplary embodiment, a method includes: receiving a resource allocation message having a notification field; and using a value of the notification field to determine a type of medium access control (MAC) header for a MAC transmission.

Abstract: A device for presenting information on a mobile includes mobiles and terminals interconnected intercommunicably through communication means, wherein a terminal transmits, to the mobile concerned, mobile identification data on a mobile to which a request for mobile information is to be made, request content identification data representing the contents of mobile information to be requested, and terminal identification data on the terminal being the presentee to which the requested contents is to be presented. The mobile acquires mobile information requested by the terminal and sends it to the terminal being the presentee. The stored contents in storage means is updated each time operation of input for requesting information from a mobile is made through the terminal and the mobile acquires new mobile information. The updated stored contents is transmitted to the terminal being the requester when the terminal requests the updated stored contents.

Abstract: A motion-based input system including a motion sensor coupled to a device. The motion sensor provides a motion signal corresponding to the movement of the device. The system further includes a processor responsive to the motion signal and configured to distinguish between a tap command and a position command and provides, in response to a tap command, one or more actions, and in response to a position command, one or more different actions to control and operate the device.

Abstract: A control device suitable for synchros comprising three stator windings. The device comprises four circuit branches with the inputs of the first and the second branches interconnected to receive a first voltage from the ends of the stator windings of the synchro transmitter and with the inputs of the third and the fourth branches interconnected to receive a second voltage from the ends of the stator windings of the synchro transmitter. Two adder elements supply control voltages to the stator windings of the synchro receiver. Two inputs of the first adder are connected to the outputs of the first and the third branches, respectively and the two inputs of the secnd adder are connected to the outputs of the second and the fourth branches. These branches have transfer functions in the form sin (.alpha.+.phi.1), sin (.alpha.+.phi.2), sin (.alpha.+.phi.3), sin (.alpha.+.phi.4), respectively, wherein .alpha. represents the information supplied by a digital element and .phi.1, .phi.2, .phi.3, .phi.

Abstract: The indications of attitude indicators at two different indicating locations that are indicating the same parameter but actuated from different sources, are monitored for the same indication by electrically interconnecting two transolvers that are mechanically coupled to the respective attitude indicator at each location. A monitor, at one indicating location, furnishes the excitation for the transolver at the other location and by the magnitudes of the sine and cosine outputs of the local transolver furnishes flag indication of any system defects of either indicator at each location.
