  • Patent number: 9118910
    Abstract: There are provided 3D image glasses which are ready for a plurality of methods (output patterns of a timing signal) different from one another and moreover which are adaptable for various types of 3D image display devices. A ROM 6 stores a plurality of output patterns, and a plurality of command signals corresponding to the output patterns. A microcomputer 5 selects from the ROM 6 an output pattern coincident with an output pattern of a timing signal received from the 3D image display device, and moreover, by a command signal of the selected output pattern, controls opening and closing of right-eye and left-eye liquid-crystal shutters in synchronization with the received timing signal.

    Abstract: A salat time alarm electronic timepiece is implemented with a one chip microcomputer. An outer read only memory is installed in the electronic timepiece for storing the sunrise time data and the sunset time data at various cities in world. The system reads out sunrise time and sunset time data from the outer read only memory and calculates five salat times of the present day. The thus calculated salat time data is stored in a storage means and compared with the current time data to provide an alarm sound when the current time reaches one of the five salat times.
