The unit includes a vibration activated switch which initially activates a blinking LED display. If, after some 15 seconds, the unit is not switched off, a built-in acoustic noise generator (7) is activated. The 15 second period is provided by a timing circuit associated with the watch ...
The circuit shown in Fig. 1 can automatically switch off any device connected to the AC mains supply after a period ranging from one to over four hours. Extending the delay period is possible by adjusting the values of the resistors used in the circuit. ...
The 74C926 is used here as a four digit counter, The transitions of temperature from earlier circuit, that is the number of times the Process value goes above the Setpoint is recorded in this. A Display switch is given to save power. A reset pushbutton can bring the counter to zero. ...
circuit selectively energizes the inner concentric electrode 14 and one bar electrode to simulate an hour hand as at B1, both the concentric electrodes and a bar electrode to simulate a minutes hand as at A1, A2, and the outer electrode 15 and a bar electrode to give a seconds display as...
