A user interface device for a data processing system is provided, which includes a sensor having a surface configured to contactingly receive a pointing device and further configured to detect physical contact by a living human and to differentiate between said physical contact and movement of the pointing device when the pointing device is engaged with the surface. The user interface device is operable to transmit information corresponding to said physical contact to the data processing system.

Abstract: Computer-implemented methods, computer program products and data processing systems for presenting dynamic data pertaining to a process. In one aspect, region information identifying a plurality of user-selected regions of the process, switching information identifying criteria for switching among the user-selected regions, and dynamic data pertaining to the process, are used to generate a dynamic visual representation of the process which emphasizes, at any given time, only one of the user-selected regions. The user-selected region emphasized at any given time is automatically determined according to the criteria for switching. In another aspect, region information identifying at least one user-selected region of the process and dynamic data pertaining to the process are used to generate a dynamic visual representation of at least a portion of the process containing the at least one user-selected region.

Abstract: An EIT system includes a plurality of voltage sources for supplying a corresponding plurality of voltages to a corresponding number of other structures, voltage source calibration means for calibrating each voltage source, and switching means for individually connecting the calibration means to each voltage source in succession during a period when each other structure is in an inactive condition. Calibrating respective voltages and currents for each voltage source compensates for shunt impedance of each voltage source. A method for calibrating the system includes individually connecting the calibration means to each voltage source in succession during a period when each other structure is in an inactive condition for calibrating all of said voltage sources in the same way.
