Abstract: An automatic display system for a gaze area has a video input unit, an object detection unit and a gaze area setting unit that sets an area containing a part or the whole of the object detected by the object detection unit, or a predetermined area in the entire video as the gaze area. A control signal corresponding to the set gaze area information is received, and a gaze area acquisition unit acquires the gaze area from the entire video according to the control signal. A video output unit outputs a video of the acquired gaze area. The video input unit, a control signal receiving unit, and the gaze area acquisition unit are disposed in the input terminal; the gaze area setting unit and the video output unit are disposed in the output terminal; and information is transmitted between the input terminal and the output terminal by wireless communication.

Abstract: The operational continuity of a programmable device, and a controller using the same is enhanced. A programmable device is configured with: an error check mechanism that detects, and notifies an error from redundantized user logic blocks; a previous value retaining section that is connected to an output terminal of a last user logic block, and takes in, and outputs an output value of the user logic blocks in each control period; a CRAM check section that receives a scan interrupt due to an error occurrence notification received from the error check mechanism, reads a scan region on the CRAM, implements error detection, and error correction, and notifies a success or failure of the error correction; and an error handling section that transmits an instruction for retaining a previous output of the user logic blocks to the previous value retaining section when the error occurrence notification is received, transmits an instruction for cancelling previous-value retention to the previous value retaining section, and also transmits a logical reset instruction to a user logic block relevant to an error when a notification of a success of the error correction is received from the CRAM check section.

Abstract: A modulation method has a high encoding rate for generating a pattern having a lower limit for the number of successive pixels in a spatial light modulator. An information recording device includes: an encoding unit that performs error correction encoding of input data; an interleaving unit that switches the output sequence of the error correction encoding unit; and an modulation unit that performs RLL modulation of the output of the interleaving unit on the basis of an RLL modulation trellis. A corresponding information reproducing device includes: a demodulation unit that uses a posteriori probability decoding based on the RLL modulation trellis, to perform RLL demodulation for reproducing recorded information; a deinterleaving unit that reverses the sequence switching; and a decoding unit that performs error correction code decoding using a posteriori probability decoding on the basis of the error correction encoding on the output of the deinterleaving unit.

Abstract: The time-series signal of the sensor is transformed to the spectral intensity by fast Fourier transform (FFT) or the like, and the one-dimensional data of the spectral intensity is generated. A pseudo image is generated, for example, by repeatedly arranging the one-dimensional data in the vertical direction, or by arranging the one-dimensional data for a plurality of sensors in the vertical direction. The state of the facility is identified by analyzing the pseudo image with an image analysis unit such as a convolutional neural network.

Abstract: Three-dimensional sensing data is transferred efficiently by applying compressed sensing using dictionary learning. Conventional image-based lossy compression improves a feature according to which power is concentrated on low-frequency components and deterioration of three-dimensional information increases. By changing the decimation rates for the depth information and the color information and using a dictionary vector created from the other restoration result for restoration, the original result is reconstructed using a small data volume.
