摘要:
A method and computer program for controlling a device in a control area network having a plurality of communication paths. The method and computer program include providing one or more first application programming interfaces, each first application programming interface including one or more first sets of functions, associating a detection algorithm with at least one of the plurality of communication paths, detecting, by the detection algorithm, the device via one of the associated communication paths, and associating one of the first sets of functions with the detected device.
摘要:
A system, method and computer program for controlling devices in a control area network that includes providing a first application programming interface containing a first set of functions in a control area network and coupling one or more functions of the first set of functions with a physical device. The control area network includes a master controller, one or more physical devices, and one or more physical communication interfaces. Coupling one or more functions of the first set of functions with a physical device. Each physical device is coupled using one or more of the physical device communication interfaces

A control system, method and computer program are provided for communicating control information in a control system. The control system includes a master controller and a plurality of devices. Each of the plurality of devices have a number of channels. Each channel has an identifying number and a plurality of channel states. The method includes at least initially directing one or more messages sent to and from each device to the master controller, sending a first type of control message from the master controller to respective devices, and sending a second type of control message and a third type of control message from the master controller to respective devices. A control message of the first type directs the respective device to place one of its channels in a specified channel state. A control message of the second type directs the respective device to set the level of a specified parameter to a certain value, and a control message of the third type comprises a character string of variable length.
摘要:
A system and method is provided for forming annotations for use with a computer that has a desktop for displaying images. Annotations are formed by one or more user interface devices, each located at a different remote location. The computer is provided with an Annotation application that generates a transparent window, or canvas, disposed to overlay all other images displayed on the desktop by other simultaneously running applications. Annotations are transmitted to the computer from respective user interface devices, and are displayed on the transparent canvas, so that the annotations likewise overlay other images displayed on the desktop. User interface devices may include a number of devices, such as other computers or touch sensitive panels.
