Patent number: 7890932Abstract: A test recording method capable of preventing omission of tests for software to be delivered. When test input data is entered from a testing client, a data transmitter transmits the data to a testing server. Upon reception of test output data and a hash value from the testing server, an evaluation unit determines a test result, pass or fail, by comparing the test output data with the output pattern described in a test specification. The result recorder stores a test log in a log memory, the test log including the test result and the hash value received from the testing server.Type: GrantFiled: September 28, 2005Date of Patent: February 15, 2011Assignee: Fujitsu LimitedInventors: Hideya Ikeda, Kentaro Nishimura, Minoru Yamamoto

Patent number: 7886366Abstract: The amplitude control of a cantilever based on the van der Pol model is performed through feedback using measurement data on a deflection of the cantilever. A self-oscillating circuit integrates a deflection angle signal of a cantilever detected by a deflection angle measuring mechanism using an integrator, multiplies a resulting integral value by linear feedback gain generated by a gain generator, and an output corresponding to the linear feedback signal is generated. Also, the self-oscillating circuit cubes the deflection angle signal using analog multipliers, integrates the resulting values using integrators, multiplies the resulting integral values by a nonlinear feedback gain generated by a gain generator, and an output corresponding to the nonlinear feedback signal is generated. Furthermore, the self-oscillating circuit adds the outputs together using an adder, and a voltage signal for a piezo element is generated.Type: GrantFiled: November 20, 2008Date of Patent: February 8, 2011Assignees: National Institute of Advanced Industrial Science and Technology, University of TsukubaInventors: Masaharu Kuroda, Kentaro Nishimura, Takashi Someya, Hiroshi Yabuno

Publication number: 20070265074Abstract: Sound generated by handclaps of a player is converted into an electric signal by a microphone, and the electric signal is inputted to a game apparatus. When a jump instruction is inputted, a player character jumps. However, the character jumps in accordance with the handclaps of the player only when the character is positioned on a jump ramp set in a virtual game world. In a case where ambient noise is inputted through the microphone when the character is not positioned on the jump ramp, the player character does not jump, but performs a provocative action. The provocative action does not exert any influence on a movement of the player character. Thus, in an action game for causing the player character to perform a predetermined action in accordance with a sound input, it becomes possible to prevent the player character from performing an action which is not intended by the player, even if the sound input is mistakenly detected.Type: ApplicationFiled: May 4, 2007Publication date: November 15, 2007Applicant: Nintendo Co., Ltd.,Inventors: Eiji Akahori, Shingo Miyata, Toshiharu Izuno, Takuji Hotta, Kentaro Nishimura

Publication number: 20070265042Abstract: Each time a player hits either one of right and left strike surfaces of a conga controller, it is determined whether: the right strike surface has been hit continuously; the left strike surface has been hit continuously; or the right strike surface and the left strike surface have been hit alternately. When the right strike surface has been hit continuously, a character in a game world is caused to move rightward. When the left strike surface has been hit continuously, the character is caused to move leftward. When the right strike surface and the left strike surface have been hit alternately, the character is caused to accelerate. Based on the above, a game program and a game apparatus, which are capable of giving various action instructions to the character of the virtual game world by using continuous inputs by a plurality of switches, can be provided.Type: ApplicationFiled: May 4, 2007Publication date: November 15, 2007Applicant: Nintendo Co., Ltd.Inventors: Eiji Akahori, Shingo Miyata, Toshiharu Izuno, Takuji Hotta, Kentaro Nishimura

Publication number: 20070265087Abstract: A forward direction line is set on a course, in a virtual game world, on which a player object is allowed to move. An advancing direction at a current position of the player object is determined based on the forward direction line. The advancing direction is determined as a direction in which the player object advances so as to control a movement of a player character in accordance with an acceleration instruction, and a leftward-rightward movement instruction from a player. Consequently, it is possible to assist the player in controlling a direction in which an object operated by the player moves.Type: ApplicationFiled: May 2, 2007Publication date: November 15, 2007Applicant: NINTENDO CO., LTD.Inventors: Eiji Akahori, Shingo Miyata, Toshiharu Izuno, Takuji Hotta, Kentaro Nishimura
