摘要:
A gateway circuit which exchanges information between a leased-line information transmission system and a power line carrier information transmission system includes a control circuit which receives and formats information transmitted over the leased-line information system and a separate control circuit which receives and formats information received over the power line carrier system. The formatted information is provided to a third control circuit which buffers the information and converts between the leased-line format and the power line carrier format to enable signal exchange between the two information transmission systems. The general control circuit responds to load control commands generated by manual switches located on the control unit and to load control commands forwarded over the leased-line system. The general control unit also contains storage elements which maintain the operating state of electrical loads on the power line and only transmit control information when an operating state must be changed.

The present invention relates to a power distribution control system for suppressing a total quantity of working current in a group of loads to a level equal to or lower than a set quantity of current by controlling the loads. The power distribution control system includes a central communication terminal and a plurality of customer communication terminals connected to the center communication terminal through communication lines. Each of the customer communication terminals is responsive to a presentation signal from the center communication terminal that requests time periods for, and quantities of power reduction. The central communication terminal also provides a response signal to selected customer communication terminals. The response signal indicates that a proposal for power reduction by the customer has been accepted.

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.

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.

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.

An air-conditioning system comprises portable devices including measurement units that measure temperature or humidity. In addition, the air-conditioning system comprises a transmitter mounted in indoor equipment that transmits light or electromagnetic waves to the portable devices, and a receiver mounted in the indoor equipment that receives detected intensity information expressing the intensity of the light or the electromagnetic waves detected by the portable devices. Furthermore, the air-conditioning system comprises a detector that detects the distance from the indoor equipment to the portable devices based on the detected intensity expressed by the detected intensity information, and a controller that controls the air-blowing state of the indoor equipment based on the detected distances and the measured temperature or humidity. Thus, the temperature or the humidity at a specified location can be adjusted more accurately.

A DMA controller comprises a reading start address register storing a reading start address from which reading starts; a reading data size register storing the size of data to be read in a single reading operation; an offset value register storing an offset value for updating the reading start address after the reading operation ends; a repetition upper limit value register storing the upper limit value of the number of times of repetition of the reading operation; and a repetition counter register storing the number of times of repetition of the reading operation. The controller of the DMA controller outputs an interrupt signal indicating that the processing of the DMA controller ends when the value stored in the repetition counter register reaches the value stored in the repetition upper limit value register.
