  • Patent number: 8887547
    Abstract: A game controller including multiple sensors for detecting a pressure load of a user for use as an input device of a game apparatus. The game controller includes a load platform adapted to receive the pressure load of the user; a plurality of load sensors arranged in the load platform for detecting the pressure load of the user, each load sensor generating an independent detected load signal; and a connector to operationally connect the plurality of load sensors to the game apparatus for transmitting a transmission signal to the game apparatus to facilitate gameplay. The transmission signal includes the independent detected load signal of at least one load sensor such that the transmission signal includes at least one independent detected load signal corresponding to at least one load sensor of the plurality of load sensors.

  • Patent number: 8387437
    Abstract: A weight measuring apparatus, in which a load platform is supported by a plurality of load sensor sections and the weight of a measurement target object placed on the load platform is measured based on a load value detected by each of the plurality of load sensor sections, is supported by a support section. Thereafter, the weight applying section applies a predetermined load to each of the plurality of load sensor sections included in the supported weight measuring apparatus.

  • Patent number: 6041702
    Abstract: A curved surface screen-printing apparatus adapted to screen-print a to-be-printed object having a large radius of curvature. Concentric curved-surface guides having an equal radius of curvature are respectively provided on both side portions of a jig table on which a printing board to be bent and used as the to-be-printed object is placed. A squeegee head crossing over the jig table, and a screen plate mounting frame are provided in the apparatus. A pair of steel belts are used to connect a corresponding one of the guides to the frame. The belts of each pair are made to intersect each other. An end of each of the belts is fixed to a side end portion of a corresponding one of the curved surface guides as viewed from a side thereof. The other end thereof is fixed to a corner portion of the screen plate mounting frame. A reciprocating motion of the squeegee head causes the screen plate mounting frame to perform a rocking motion along the curved surface of the jig table.

  • Patent number: 5897253
    Abstract: A device for making a master plate for printing braille includes a support table on which a master plate material is positionable. A punch is disposed on a first side of the master plate material. A punch die is positioned in alignment with the punch, and is arranged on a second side of the master plate material. A punch driver is connected to the punch, and is activateable to move the punch toward the master plate material. A shifter arrangement is provided for changing a relative position of the master plate material to the punch and the punch die. A controller is operatively connected to the shifter and the punch driver for controlling an operation of the shifter and the punch driver. A data supply arrangement is coupled to the controller, and supplies punching data thereto.
