A demodulator demodulates a voltage signal based on the potential difference between the communication wire and the shared wire, and outputs the signal as a demodulated signal. A connector connects the communication wire and the shared wire to the modulator and the demodulator by means of a high voltage capacitor that withstands voltages up to a predetermined level. A controller receives, as incoming data, serial data corresponding to a voltage signal demodulated in demodulator if the serial data includes an address of its own apparatus, monitors a demodulated signal outputted from the demodulator, and outputs transmission data that includes a destination address to the modulator if the controller determines that no signal is being transmitted in the communication wire. | 12-05-2013 |
20140306887 | CONTROL DEVICE AND REMOTE CONTROL DEVICE - A control device includes a storage device for prestoring rendering command data, a central processing device, and a rendering processing device. The rendering command data is data for generating a rendering command executed in order to generate display data indicating a display image to be displayed on a display device. The central processing device refers to a screen management table when a predetermined rendering condition is satisfied, and specifies and outputs rendering command specifying data corresponding to the satisfied rendering condition. The rendering processing device acquires the rendering command data specified by the outputted rendering command specifying data from storage device, generates display data based on the acquired rendering command data, and outputs the display data to the display device. | 10-16-2014 |
20140347378 | CONTROL DEVICE, CONTROL METHOD, AND PROGRAM - A remote control, upon determining that a power-saving flag is on, or in other words, upon determining that the remote control is conducting power-saving operating behavior, decides on a monochrome image stored in a reduced image memory as image information to be read by a renderer. The monochrome image has ⅛ the amount of information compared to a color image stored in a normal image memory. Consequently, in the case of power-saving operating behavior by the remote control, the renderer is able to read a monochrome image stored in the reduced image memory with less power compared to the case of reading a color image stored in the normal image memory. Consequently, power consumed in the remote control may be restricted in the case of power-saving operating behavior by the remote control. | 11-27-2014 |
20150142357 | ANALYSIS DEVICE, ANALYSIS METHOD, AND PROGRAM - A switcher transmits, to an extractor/signal determiner, a converted current signal generated by a current-voltage converter when a converted current signal determiner determines that the converted current signal is generated by transmission of a current signal over a communication line, in the meantime, performs a switch-over so as not to transmit, to the extractor/signal determiner, a converted voltage signal generated by a voltage sensor. In addition, the switcher transmits, to the extractor/signal determiner, the converted voltage signal when a converted voltage signal determiner determines that the converted voltage signal is generated by transmission of a voltage signal over a communication line, in the meantime, performs a switch-over so as not to transmit, to the extractor/signal determiner, the converted current signal generated by the current-voltage converter. | 05-21-2015 |

20130293538 | OBJECT OPERATING DEVICE AND METHOD, AND PROGRAM - Motion data to be inserted between two different object actions that include a rotating action and are to be successively performed are generated so that the two actions are smoothly connected. Respective elements d required to define a transitional motion action are calculated from the respective frames after the end point of the former motion and before the start point of the latter motion. As for the three-dimensional rotation R(t) that defines the posture in each frame, independent linear values rx(t), ry(t), and rz(t) are calculated as values approximating the three-dimensional rotation R(t) by using exponential maps. The velocity components of the respective elements d are determined, and the largest value of the absolute values of the velocity components in each of the post-end frames and the pre-start frames is extracted as an interpolating velocity v(t). The respective elements d(t) in each of blended transitional motion frames can be determined. | 11-07-2013 |
20130307850 | ACTION MODELING DEVICE, METHOD, AND PROGRAM - Actions of a player character in a virtual three-dimensional space are determined for each of the extremities. The position of the end portion of each extremity is determined in the local coordinates of the extremity, with the fixed portion being the reference position. The position of the end portion is determined within a pre-defined range of access, then the joint angle of the intermediate portion is fixed, and the position of the intermediate portion is determined from the angle of rotation about the axis connecting the fixed portion and the end portion. The position of the intermediate portion is determined as angular information within the range of motion of the intermediate portion, which is defined in accordance with the position of the end portion. The shape of each extremity of the character is determined by the positional information about the end portion and the angular information about the intermediate portion. | 11-21-2013 |
20140139529 | INFORMATION PROCESSING APPARATUS, CONTROL METHOD, AND RECORDING MEDIUM - An information processing apparatus selects a plurality of interval width sequences of internal knots of a nonuniform B-spline that approximates waveform data, based on a multivariate normal distribution, and then determines a knot vector based on each of the selected interval width sequences and an optimal control point sequence for each knot vector. Also, the apparatus repeats, for a nonuniform B-spline that is defined for each combination of a knot vector and an optimal control point sequence corresponding to the knot vector, the selection of interval width sequences, the determination of knot vectors and optimal control point sequences and the evaluation thereof, until an evaluation whose objective function is minimized is obtained. | 05-22-2014 |
