A dental floss device comprises an elongated handle with a U-shaped flossing head projecting from one end of the handle. A strand of dental floss originated from a supply spool containing pre-wound fresh floss passes through the flossing head and emerges back to a take-up spool for containing spent floss. Dispensing floss and providing tension on the floss are controlled by the fingers of the holding hand on both supply spool and take-up spool which are rotatably mounted on the handle. The spools are also detachably mounted on the handle so that spent floss can be discarded and the take-up spool can be cleaned at will with ease and exhausted supply spools can easily be replaced with new, pre-wound spools like cartridges thus making the device reusable.

A buck regulator circuit provides a low voltage, e. g. , about 15 V, power source, directly from a variable high-voltage dc bus voltage that varies from 250 V to about 450 V. A monolithic gate driver circuit is used to drive the switching device, e. g. , a MOSgate transistor, which delivers the high voltage dc to the load output node via a charging inductor for controlled time periods. The control principle for controlling the on and off times of the transistor (with the monolithic gate driver circuit) relies on turning on the transistor for fixed time periods that are equal to the intrinsic delay of the gate driver circuit. In contrast, the off period of the switching device is varied to regulate and maintain the output voltage at a constant value, independent of the input dc bus voltage or of the output current.

A laser. In some embodiments, the laser includes an optical amplifier, and an output reflector. The output reflector may be configured to receive light from the optical amplifier and to reflect light at a first wavelength back toward the optical amplifier. The output reflector may include a wavelength-selective element, and a coupler configured to receive the light from the optical amplifier and to couple a portion of the light to the wavelength-selective element.
