摘要： One embodiment of the present invention sets forth a technique for emulating left, right, and center mouse button functionality for a multi-touch input device to provide end-users with full mouse functionality. Various finger to mouse button mapping techniques are used to specify the left, right or middle mouse buttons. A single finger is used for tracking while a second finger or thumb is used to activate or deactivate one of the mouse buttons. Multi-finger mouse emulation enables more precise cursor control, while avoiding occlusion of the cursor and end-user fatigue, thereby improving the overall end-user experience.

摘要： A two-wire process variable transmitter for use in an industrial process, including a process variable sensor configured to sense a process variable of a fluid of the industrial process. Output circuitry is configured to provide an output on a two-wire process control loop which is related to the sensed process variable. Loop current measurement circuitry measures a loop current flowing through the two-wire process control loop and terminal voltage measurement circuitry measures a voltage related to a terminal voltage of the process variable transmitter. The terminal voltage can be a voltage measured across an electrical connection of the two-wire process variable transmitter to the two-wire process control loop. Input circuitry is configured to receive a diagnostic command from the two-wire process control loop. A microprocessor configured to perform loop diagnostics on the two-wire process control loop based upon the measured loop current and terminal voltage in response to receipt of a diagnostic command from the two-wire process control loop.
