Abstract: A computer system displays a first user interface object and detects a first input directed to the first user interface object. If the first input does not meet a first input threshold and includes less than a threshold amount of movement, the computer system changes a mode of a control function corresponding to the user interface object from a first mode to a second mode; if the first input meets the first input threshold and includes less than the threshold amount of movement, the computer system displays a second user interface object that includes information corresponding to the control function; and if the first input meets the first input threshold and includes more than the threshold amount of movement after meeting the first input threshold, the computer system adjusts a respective control value of the control function in accordance with a movement of the first input.

Abstract: A data switching node includes a plurality of data lines including high speed data (link) lines and low speed data (port) lines and a switch connected to the data lines. The switch is a distributed multiplexer comprising a number of switching modules connected in common to a data bus. The switching modules are arranged to communicate data with the common data bus. A control module is also connected to the bus and arranged to control the addressing of the switching modules so that data received by a switching module connected to one data line is transmitted directly via the common data bus to a switching module connected to a selected other one of the data lines in response to a control signals from the control module identifying the said switching module, the data being transmitted in association with a logical channel number associated with the switching module connected to the selected other one of the data lines.
