Abstract: A state display device capable of reducing a processing load applied to a microcomputer by performing part of a GUI process by hardware and a display method of the state display device are obtained. A rendering processing device starts a process in response to a rendering request stored in a rendering request region when a starting command is stored in a start/end instruction register. When a rendering request specified by an instruction address is a rendering termination request, the rendering processing means terminates the process performed in response to the rendering request, stores a termination factor in an interruption factor register, and issues an interruption to a central processing device.

Abstract: 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 ? 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.

Abstract: An operation terminal for remotely operating an electronic apparatus includes a processing unit for remotely communicating with the electronic apparatus in accordance with a program, a memory on which the processing unit performs writing or reading of data, a nonvolatile memory for storing a basic screen image drawing command for drawing a basic screen image that is displayed before the operation terminal is operated, a drawing processor for creating a bitmapped image of the basic screen image in accordance with the basic screen image drawing command, and a display unit for displaying the bitmapped image on a screen.

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.

Abstract: 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.

Abstract: An application program changes a property value of a graphic object arranged in an object database. An object manager reads out the property value from the object database and then issues a drawing command. A graphics engine executes the drawing command to configure a memory image of the graphic object on a VRAM to display the image on a liquid crystal display via an LCDC.

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.

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.

Abstract: A frequency characteristics measurer is disposed in the vicinity of an end of refrigerant piping, the end of which is connected to an outdoor unit, that connects the outdoor unit and an indoor unit of an air conditioner, and measures frequency characteristics of the refrigerant piping. A filter is attached at a position between the outdoor unit and a position where a terminal of the frequency characteristics measurer is connected, so as to wrap the refrigerant piping. A piping length calculator is connected to the frequency characteristics measurer via an interface cable, and acquires, via the interface cable, frequency characteristics measured by means of the frequency characteristics measurer. The piping length calculator extracts a lowest anti-resonant frequency from the acquired frequency characteristics, and calculates the length of the refrigerant piping on the basis of the extracted lowest anti-resonant frequency.

Abstract: Unit data, which constitutes digital data is extracted as 8-bit units of parallel data by a control section and outputted to a buffer. Thereafter, in a process where the unit data is transmitted from a serial interface to a display unit, the unit data is converted to parallel data in a format required by the display unit. Thereby, it becomes unnecessary for the control section to perform processing of converting the digital data to a format required by the display unit. Consequently, the load on the control section is reduced.
