A video device controller (101) and method for generating a key code enable key code generation by a single instance of manipulation of the controller by a user The video device controller (101) includes a touch pad (110) having a predetermined touch pattern; a coordinate recognition unit (120) for recognizing coordinate values corresponding to a touch trajectory executed with respect to the touch pad (110); a key signal input unit (130), having a plurality of keys, for generating a key signal according to a user selection, the plurality of keys including at least one hotkey corresponding to a set of video device functions; a system controller (140) for generating, in response to a user operation of the hotkey, an OSD command signal for displaying an OSD keypad having a set of menu items corresponding to the video device functions, the OSD keypad being configured according to the predetermined touch pattern, for calculating values of at least one of a direction, speed, and distance of the touch trajectory using the recognized coordinate values, and for outputting a movement command signal based on the calculated values and the key signal, the movement command signal shifting an object among the OSD menu items displayed on the video device; and a key code generator (150) for respectively generating a key code corresponding to the OSD command signal and a key code corresponding to the movement command signal.

Method of generating key code in coordinate recognition device and video device controller using the same

The invention relates to a module arrangement of safety switching devices, comprising at least one input module (18) for processing the signals of a transmitting safety device (20) and for generating output signals; and at least two output modules (19; 19.1, 19.2) for controlling an actuator (21) according to the output signals. The input module (18) and the output modules (19) are arranged in a series, forming a module series, and the input module (18) is allocated to an output module (19). The inventive module arrangement is characterized in that the input module (18) is allocated to the first, second or both output modules (19) according to the position of the input module (18) in the module series.

Safety switching device module arrangement

The invention relates to a modular automation system, whereby a central automation device (1.1, 1.2, 1.3) may be installed and upgraded by the application of several optional base boards (2.1, 2.2, 2.3) permitting various upgrades. The automation device (1.1, 1.2, 1.3) may be upgraded by the application of one of several central units (3.1, 3.2, 3.3), which have differing data processing power and data storage capacity with uniform external dimensions. At least one I/O device (7) may be directly coupled to the central unit (3.1, 3.2, 3.3). Each of the optional base boards (2.1, 2.2, 2.3) may be fitted with at least one communication coupler (4.1, 4.2, 4.3) for a field bus connection to a remote I/O unit (6).

The present invention relates to an information processing apparatus allowing proper communication with a communication partner in accordance with a communication time of the communication partner.

Information processing apparatus and method, recording medium and program

The invention releases to a kind of programming logic control, specially a kind of programming logic control, the expansion module and the hardware expansion method of it. The characteristic of the expansion module of programming logic control is that it comprises an address transfer unit which is used to extend the address signal of the bus based on some rules and than to continue passing on along the bus. At least one part of the address signal is put to the mainly control unit through the signal line. The invention also published a kind of programming logic control and the hardware expansion method of it. The invention can make the exemption address design between the conterminous main module and the expansion module come true. It also supports the directly interview from the main module to the expansion module. The main module can remove the addressing signal at any moment based on the need of itself and start up a new link or rebuild a link, which can effectively support the interview to the expansion module.

Programmable logical controller, its expanded module and its hardware expanding method

A universal expansion module interfaces a logic controller to a plurality of types of input/output expansion modules that communicate input/output data between the controller and automated devices. A communication interface establishes communication between the controller and at least one of the plurality of types of an input/output expansion module. An expansion module having a physical configuration accommodates signals from the plurality of types of input/output expansion modules.
