Abstract: An automatic cleaning system is configured by a single controlling apparatus, and a plurality of self-traveling cleaners. When the controlling apparatus has received from a self-traveling cleaner a dust location signal containing a dust location detected by the self-traveling cleaner, it writes the received information into a storage unit. When the controlling apparatus has received from one of the plurality of self-traveling cleaners, with respect to dust which is not removed by any self-traveling cleaner, a signal requesting a reservation of removing the dust, the controlling apparatus will not accept from any other of the plurality of self-traveling cleaners a signal requesting a reservation of removing the dust, until receiving from the one self-traveling cleaner information indicating that removing of the dust has been completed or information indicating that the removing of the dust has been stopped.

Abstract: A communication unit receives spraying target information indicating a spray target. A spraying target detector detects the spray target indicated in the spraying target information in space. A spray control unit is a unit that performs ion-spraying processing on the spray target at a predetermined frequency. In the ion-spraying processing, the spray control unit determines a moving direction of an ion spraying apparatus from a current location to the detected spray target, and sprays ions on the spray target when a distance between the spray target and the ion spraying apparatus is within a first threshold value. A flight control unit controls a flight of the ion spraying apparatus in the moving direction.

Abstract: An information security apparatus and a security system, which prevent eavesdropping on input information input by an input device and identify eavesdroppers, includes a key input interface unit inputting secret information returns a decoy key input value when receiving a read access from unprotected domain 1011. Further, a payment-processing company, which judges whether it is possible or not to use a service such as electronic payment-processing, provides the information security apparatus with an immediate value to be used as the decoy key input value when performing an authentication. Accordingly, a person who attempts to eavesdrop on the input from a key input unit acquires the decoy key input value. If the decoy key input value is used when requesting payment-processing company to perform an authentication, the payment-processing company recognizes the person who requests the authentication as an eavesdropper.

Abstract: In a display control circuit for controlling a display of a display device, data which is stored in a memory is inputted to a FIFO circuit by a DMA controller, and the FIFO circuit transmits the stored data to the display device at a rising edge of an inputted clock PCLK. A clock mask circuit transmits the inputted clock PCLK to the display device as a display clock PCLK? while the FIFO circuit is not underflow. On the other hand, the clock mask circuit masks the inputted clock PCLK while the FIFO circuit is underflow, and transmits the display clock PCLK? whose level is kept high to the display device. As a result, a display position of display data does not shift even if underflow occurs in the FIFO circuit.

Abstract: Provided are an information security apparatus and a security system which prevent eavesdropping on input information input by an input device and identify eavesdroppers. In information security apparatus 1, key input interface unit 106 which is an interface for inputting secret information returns a decoy key input value when receiving a read access from unprotected domain 1011. Payment-processing company 4, which judges whether it is possible or not to use a service such as electronic payment-processing, instructs, to the information security apparatus 1, an immediate value to be used as the decoy key input value when performing an authentication. Accordingly, a person who attempts to eavesdrop on the input from key input unit 107 acquires the decoy key input value. If the decoy key input value is used when requesting payment-processing company 4 to perform an authentication, payment-processing company 4 recognizes the person who requests the authentication is an eavesdropper.

Abstract: A line image which comprises one line parallel to the juxtaposing direction of light-emitting elements is extracted from a three-time image, and a work region is determined, in which, in the juxtaposing direction, an M sub-pixel is added to the front side of the line image and an N sub-pixel is added to the rear side thereof. A background image of a region corresponding to the work region is read out from the frame memory. The read out background image whose precision is made the same as that of the three-time image in a pseudo state, and the line image are blended to obtain a blend image. Image data resulting from the blend image are written in a region corresponding to the work region of the frame memory. The above process is repeated for all lines of the three-time image.

Abstract: An image data is filtered to output filtered image data, the filtered image data is stored to a frame memory, and each of a plurality of light emitting elements of a display device is controlled according to the filtered image data in the frame memory to make the display screen display the image data. When a first figure and a second figure are drawn adjacently, the first figure and the second figure are extended such that the first figure and the second figure have an overlap area. Thanks to the overlap area, a background image does not affect in the overlap area, thereby a front of discontinuity, which is not expected, does not appear.

Abstract: A decryption unit decrypts encrypted content to generate content. An instruction execution unit outputs a transfer destination address showing a position in a content output unit to an address detection unit. The address detection unit judges whether the transfer destination address matches a pre-stored permitted address, and outputs the generated content only when the transfer destination address and the permitted address match, to the position in the content output unit shown by the transfer destination address. The content output address receives the content and outputs the received content to an external device.
