Abstract
Driving power for a vibrating device (10) is provided at less than full level when the device is initially used. Power is gradually increased in successive steps after a selected number of uses in each step until full power is achieved.
Also, a battery-energized driving signal for a vibrating device has a selected characteristic, such as duty cycle, which is set initially at less than an optimum value, when the battery which is contained within the driver assembly (22) is at full strength. As the battery discharges, the selected characteristic is adjusted toward optimum so as to compensate for reduction in the battery voltage and ensure full power output.
Also, a battery-energized driving signal for a vibrating device has a selected characteristic, such as duty cycle, which is set initially at less than an optimum value, when the battery which is contained within the driver assembly (22) is at full strength. As the battery discharges, the selected characteristic is adjusted toward optimum so as to compensate for reduction in the battery voltage and ensure full power output.
Claims (5)
1. A system for maintaining adequate power to a battery-powered vibrating device, which is to be used on the human body, as battery voltage decreases, comprising:
means, energized by a battery, for generating a driving signal to operate a vibrating device, wherein a selected characteristic of the driving signal is initially set at less than optimum value when the battery is at full voltage;
means for monitoring the battery output to determine when the battery has discharged to a first selected level; and means for adjusting said characteristic toward an optimum value when the battery voltage decreases below said first level, so as to maintain normal operation of the device.
means, energized by a battery, for generating a driving signal to operate a vibrating device, wherein a selected characteristic of the driving signal is initially set at less than optimum value when the battery is at full voltage;
means for monitoring the battery output to determine when the battery has discharged to a first selected level; and means for adjusting said characteristic toward an optimum value when the battery voltage decreases below said first level, so as to maintain normal operation of the device.
2. A system of claim 1, including means for changing the characteristic toward said optimum value each time the battery value decreases below selected successively lower levels.
3. A system of claim 1, including means for stopping operation of the apparatus when said characteristic is at an optimum value and the battery voltage thereafter decreases below a selected minimum level.
4. A system of claim 1, wherein said characteristic is duty cycle.
5. A system of claim 1, wherein said characteristic is frequency.
