  • Publication number: 20160176052
    Abstract: A robot control device comprises a mass parameter setting unit which sets a mass parameter, and a stop command unit which sends a stop command of a robot. A first upper limit value regarding external force and a second upper limit value smaller than the first upper limit value have been set.

  • Publication number: 20160165255
    Abstract: A video encoding device (2) includes a side information determination section (21) and a side information encoding section (22). The side information determination section (21) sets a quantization parameter for each macroblock in such a manner that a difference between quantization parameters for each pair of macroblocks with successive encoding orders is equal to one of n difference values, and transforms the difference into one of n indices with respect to each pair. The side information encoding section (22) generates a binary sequence having a length corresponding to the size of the absolute value of the index. The total of absolute values of the n indices is smaller than the total of absolute values of the n difference values.

  • Patent number: 9357219
    Abstract: While maintaining a high degree of freedom in choosing partition sizes and transformation sizes adapted for local characteristics of videos, the amount of metadata is decreased. A video encoding apparatus (10) divides an input video into blocks of a prescribed size and encodes the video block by block. The video encoding apparatus is provided with: a prediction parameter determining portion (102) that decides the block partition structure; a predictive image producing portion (103) that generates predictive images, partition by partition, as prescribed by the partition structure; a transform coefficient producing portion (107) which applies one of the frequency transformations included in a prescribed transformation preset to prediction residuals, i.e. the differences between predictive images and the input video; a transform restriction deriving portion (104) which generates the list of transform candidate, i.e.

  • Publication number: 20160031077
    Abstract: A robot controller for ensuring safety of an operator, which is capable of reducing operational cost by avoiding unnecessary emergency stop of a robot. A teaching pendant has an emergency stop button for interrupting drive power for the robot, and a main body of the controller has a signal part which receives an emergency stop signal from the teaching pendant when the emergency stop button is pushed, and a power interrupting part which interrupts the drive power for the robot when the signal part receives the emergency stop signal under a predetermined condition. Until a first predetermined period of time has passed after a connection/disconnection switch is operated, the power interrupting part does not interrupt the drive power when a connection-recognition signal representing that the teaching pendant is connected to the main body is not generated, even when the emergency stop signal is input from the teaching pendant.
