  • Patent number: 8807444
    Abstract: An air conditioning equipment having an in-room unit connected to one end of the refrigerant pipes and an out-room unit connected to the other end of the refrigerant pipes. The air conditioning equipment includes signal coupling portions which are respectively disposed at both end parts of the refrigerant pipes. Each of the signal coupling portions couples an alternating current (AC) control signal to the refrigerant pipes and exhibits a predetermined impedance with respect to an AC electric signal. The configuration of the air conditioning equipment brings forth the advantages that the electrical insulation devices used in the prior art are dispensed with, and the signal transmissions between the in-room unit and the out-room unit can be performed by a simple apparatus configuration.

  • Publication number: 20140153378
    Abstract: An electric field intensity measuring circuit measures the electric field intensity of each of multiple communication channels available for data communication. A channel determiner compares electric field intensities measured by an electric field intensity measuring circuit with multiple different thresholds including a first threshold as the carrier sense threshold and a second threshold that is the detrimental interference level the interference of which causes the reception sensitivity to deteriorate, counts the numbers of times that the electric field intensity exceeds the thresholds on each communication channel, and selects a communication channel for use based on the counted numbers of times that the thresholds have been exceeded on the communication channels.

  • Patent number: 8736631
    Abstract: The display color of, for example, a button image responsive to a command input into a facility operation display device is controlled by a palette value having a smaller number of bits than an RGB value. When the display color of the button image is changed, the palette value of a drawing object associated with the button image is changed to an RGB value. This eliminates the necessity of incorporating, for example, a high-performance CPU as a central arithmetic unit. In addition, it is not necessary to pre-store images corresponding to several kinds of display colors specified by RGB values, to thereby eliminates the necessity of incorporating, for example, a high-capacity storage medium in the facility operation display device. Accordingly, the device cost can be reduced.

  • Patent number: 8727879
    Abstract: An inclination of a first unit is detected based on an output from a first acceleration sensor provided in a first unit of a controller, and an inclination of a second unit is detected based on an output from a second acceleration sensor provided in a second unit separate from the first unit. A difference between the inclinations of the first unit and the second unit is detected, and game control is performed using the detected difference. Thus, with a game apparatus using a plurality of acceleration sensors or a plurality of sensors capable of detecting a motion or a posture, a dynamic play is made possible with a high degree of freedom of motion and an intuitive motion input is realized.

  • Publication number: 20140015706
    Abstract: A presence detection system is equipped with a transmitter that transmits a multipath wireless signal and a receiver that detects the presence of a person by receiving the transmitted wireless signal, within a prescribed space. On the basis of the reception level for a wireless signal received intermittently at the beginning of a first interval, the receiver determines whether there has been a change in the present/absent state of a person. When it is determined that there has been a change in the present/absent state of a person, the receiver determines whether a person is present/absent on the basis of variation in the reception level for a wireless signal received at the beginning of a second interval, which is shorter than the first interval.

  • Publication number: 20130328899
    Abstract: A DMA controller reads image information recorded on a ROM by address unit from a front reading start position. A shift operator shifts a first data sequence of one row of the reading by only a designated number of bits, and generates a second data sequence. A DMA controller reads a third data sequence already stored in a VRAM writing start position. A controller performs a prescribed operation on the second data sequence and the third data sequence, and generates a fourth data sequence. The controller writes the generated fourth data sequence successively in a horizontal direction by address unit from the VRAM writing start position.

  • Publication number: 20130325191
    Abstract: A modulator modulates a voltage signal corresponding to inputted transmission data, and outputs the signal as a voltage signal between a communication wire and a shared wire. 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.

  • Publication number: 20130293560
    Abstract: A DMA controller operates independently from a CPU, reads image data stored on an ROM sequentially in given units from the first reading start position of the image data and writes the image data into a buffer. A DMA controller operates independently from the CPU, writes the data read into the buffer to a VRAM one byte at a time from the writing start position. The controller of a companion chip updates the writing start position in the VRAM to the position of the same column in the next row each time writing the data string in each row is completed.

  • Publication number: 20130287075
    Abstract: A sampler samples a receive signal received via a dedicated communication line. A data transfer rate adjuster measures a data transfer rate based on a number of start bit samples contained in the receive signal. A bit determiner makes a bit determination regarding the receive signal at the data transfer rate measured by the data transfer rate adjuster, to thereby acquire serial data contained in the receive signal. A transmitter sends, via the dedicated communication line, a transmit signal containing serial data sent by an MPU. An MPU communicator outputs to the transmitter the serial data sent by the MPU, and outputs to the MPU the serial data acquired by the bit determiner. The data transfer rate adjuster adjusts, when the transmitter sends the transmit signal multiple times at different data transfer rates, the data transfer rate based on the receive status of respective response signals thereto.
