  • Publication number: 20200265256
    Abstract: A device for analyzing a worker's work state, the analysis involving generation of determination data for determining whether worker's manual work is performed in a predetermined work order. This device includes imaging and setting units. The imaging unit images, a work video, a worker's manual working state in which the worker repeatedly performs predetermined work. This predetermined work is performed by repeating a plurality of fundamental work operations by hand. Based on a predetermined motion which is previously set for each of the fundamental work operations, the setting unit sets delimitation information to delimit the work video every fundamental work operation at a timing when the predetermined motion is detected. In the device, a generation unit generates determination data which includes both the imaged work video and the set delimitation information. Based on the determination data, the worker's manual work can be analyzed in various ways.

  • Patent number: 10671074
    Abstract: A control system for a work vehicle includes a sensor and a controller. The sensor outputs a signal indicating an actual traveling direction of the work vehicle. The controller communicates with the sensor. The controller is programmed so as to execute the following processing. The controller acquires the actual traveling direction of the work vehicle. The controller sets the actual traveling direction as a target traveling direction when a condition that indicates that the work vehicle has started straight travel has been met. The controller calculates a bearing difference between the target traveling direction and the actual traveling direction. The controller moves the work implement at a target tilt angle corresponding to the bearing difference so as to reduce the bearing difference.

  • Patent number: 8605792
    Abstract: A coding apparatus is for performing a deblocking filter process by dividing input moving image data into frames, and coding the moving image data by dividing the frames into macroblock lines and by shifting and changing, for each frame, a refresh area in which an amount of coding information allocated to a specific macroblock line is larger than that of another macroblock line. The coding apparatus includes a determining unit that determines that a refresh area in a current frame as well as a macroblock line in the current frame corresponding to a macroblock line that will become a refresh area in a frame being subsequently subjected to the coding process becomes a next refresh area. The coding apparatus includes a coding unit that codes the refresh area and the next refresh area by allocating a larger amount of coding information than an amount allocated to the other macroblock line.

  • Patent number: 8150171
    Abstract: In a moving picture decoding apparatus, a variable-length decoding circuit decodes motion vectors for each macroblock from a bit stream and stores the motion vectors. An error correction circuit calculates a reference vector for an error macroblock using the motion vectors to generate a corrected picture from a reference picture. An inverse-orthogonal transform circuit stores a difference value between direct-current (DC) components after Inverse Discrete Cosine Transform (IDCT) is performed thereon, in the memory for each macroblock. The error correction circuit further calculates a difference value of the DC component of the error macroblock using the difference values of DC components stored in the memory, to add the difference value calculated to the corrected picture generated from the reference picture.

  • Patent number: 8036266
    Abstract: Each of a plurality of encoders calculates a first time by adding an encoding delay time commonly determined between the encoders to a value of an STC counter, and transmits a system stream generated by including the calculated first time to a decoder associated with the encoder in one-to-one correspondence, of a plurality of decoders constituting a decoding system. Each of the decoders calculates a second time by adding the first time to an estimated maximum value commonly determined between the decoders by adding a decoding delay time to a value of stream fluctuation of an output time occurring between the encoders, and outputs the divided image data decoded from the system stream to a synthesizer that synthesizes the image data at the calculated second time.

  • Patent number: 7395679
    Abstract: Molten glass is press-molded by a metallic die in which a cylindrical body is provided in a vertically standing manner at a central part of a bottom surface of a bottomed hole and a molding surface corresponding to a chamfering shape of an outer peripheral edge surface of a glass substrate is consecutively formed in an inner peripheral wall, and a glass substrate precursor provided with the chamfering shape axially consecutive on an outer peripheral surface thereof and a through hole formed at a central part thereof is thereby formed. The glass substrate precursor is cut perpendicular to an axial direction to be separated into respective glass substrates. Next, the respective glass substrates are subjected to a lapping process and a polishing process, if necessary, to produce a glass substrate as a final product. According to the manufacturing method, a glass substrate for information recording medium whose inner and outer peripheral edge surfaces are chamfered can be manufactured with an improved efficiency.
