Abstract: A method of an embodiment of the invention is disclosed that comprises detecting a turn-off event for an device. The device has an on mode, a sleep mode in which the device consumes less power than in the on mode, and an off mode in which the device consumes less power than in the sleep mode. In response to detecting the turn-off event, the method causes the device to enter the turn-off mode, by turning off power to all components of the device except to one or more components thereof that monitor detection of a turn-on event to cause the device to subsequently exit the off mode.

Abstract: A pen controller in a thermal printer generates a pulse width modulated (PWM) signal based on a reference voltage. The PWM signal is passed through a filter, resulting in a first voltage that varies with the duty cycle of the PWM signal. Additionally, a temperature sensing resistor on a pen of the printer generates a second voltage that varies with the temperature of the pen. A comparator is used to compare the first and second voltages to determine when the pen is at a proper temperature for printing. As the actual reference voltage in a printer may vary from its intended value due to variations in the fabrication process used to create the components of the printer, the printer is calibrated to account for such variations. The printer is calibrated by the pen controller changing the duty cycle of the PWM signal (thereby changing the first voltage) while the second voltage remains relatively constant.

Abstract: A variable rate defibrillator charging circuit includes a power transformer that accepts an internal battery output and the output from an AC-to-DC converter on separate primary windings. The secondary winding of the transformer is coupled through a rectifier to a storage capacitor. The transformer operates in a fly-back mode whereby energy is discharged into the storage capacitor when the power supplies discontinue charging the transformer. After energy in the transformer is discharged into the storage capacitor, the power supplies are reactivated, recharging the transformer. The separate primary windings of the transformer provide a fast, reliable, low cost means for charging the storage capacitor with multiple power supplies. The AC power source feeding the AC-to-DC converter is detachable allowing the defibrillator to be operated remotely whereby the storage capacitor is charged solely from the internal battery.
