Abstract: A variable temperature electronic faucet water supply system provides a plurality of preset water temperature settings from which the user may select a desired water temperature by pressing a temperature selection button. If no water temperature is selected by the user, the faucet automatically delivers water at a default temperature setting. The faucet water supply system includes a motion detector mounted in the head of the faucet which will detect motion near the faucet head. The water is delivered from the faucet head at the preselected temperature when motion is detected near the faucet head. Water is delivered at the preselected temperature for up to two seconds after motion is last detected near the faucet.

Abstract: A system for providing a plurality of timers to perform the timing of event occurrences wherein, for each event, there corresponds a timer control block which stores in its time-flag field (Tf) an indication of whether the timer control block is chained or unchained, running or stopped, in its time-out field (Tv) the expiration time interval and in its time-stamp field (Ts) the current time as a reference at each interruption. The timer control blocks are chained by a one-way link according to their expiration times in such a way that each timer chain contains the timer control blocks whose events will occur at the same time. A cyclic table of index values classifies the timer chains according to their expiration times.
