  • Publication number: 20260065624
    Abstract: The display device includes an acquisition processing unit, a rectangle candidate detection processing unit, and a one-character extraction processing unit. The acquisition processing unit acquires image data including characters. The rectangle candidate detection processing unit detects a rectangle candidate of a character from the image data, and calculates a reliability of the detected rectangle candidate. The one-character extraction processing unit corrects, in a case where a first rectangle candidate and a second rectangle candidate detected by the detection processing unit at least partially overlap each other, a reliability of a rectangle candidate to be corrected out of the first rectangle candidate and the second rectangle candidate by using a calculation method for a degree of overlap selected according to a relationship between a type of a first detection target corresponding to the first rectangle candidate and a type of a second detection target corresponding to the second rectangle candidate.

  • Patent number: 9581992
    Abstract: In a conventional CAM apparatus, cutting regions and a tool axis angle by which the cutting time is minimized cannot be automatically set for a finish shape having a free formed surface shape. Accordingly, the CAM apparatus generates quadrangle-shaped patterns of cutting regions using coordinate data of a finish shape and an initial shape. Triangle-shaped cutting regions are generated for concave-convex faces of the finish shape. For cutting regions generated by subtraction by boolean operation with a subtract shape calculated by subtraction by boolean operation between the initial shape and the finish shape, the tool axis angle is set so that the tool does not interfere and the face is maximized. For other regions, the tool axis is set so as to satisfy a remainder standard and to minimize a tool path length.

  • Patent number: 9547301
    Abstract: In order to easily verify an operation of the machine tool, a machining support apparatus includes a machining monitoring unit 112, a simulation processing unit 113, and a display unit 150. The machining monitoring unit 112, upon receiving a notification indicating detection of a simulation start code programmed in a machining program from a machine tool controller controlling a machine tool via a communication device 130, renders the machine tool controller to stop the machine tool. The simulation processing unit 113 simulates instructions from the simulation start code to a simulation end code in the machining program, while the machine tool is stopped. And the display unit 150 displays a simulation performed in the simulation processing unit.

  • Patent number: 8542835
    Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover.
