Abstract
Driving power for a vibrating device 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 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.
Claims9
A system for gradually increasing power to a vibrating device used on the human body, comprising:
- means for producing driving power to a vibrating device in response to a driving signal;
- means for providing less than full driving power to the vibrating device at a first selected point in time;
- and
- means for increasing the power in successive steps in response to selected successive uses of the device by the user, until substantially full power is achieved.
