Abstract: A multi-module wearable device. According to an embodiment of the present disclosure, there is provided a system, including: a first wearable instrument; a second wearable instrument including a biometric sensor; an electrical connection between the first wearable instrument and the second wearable instrument; and a strap, sized and dimensioned to be disposed about a wrist. The electrical connection may be capable of connecting the first wearable instrument to the second wearable instrument when the second wearable instrument is at a first position on the strap relative to the first wearable instrument, and of connecting the first wearable instrument to the second wearable instrument when the second wearable instrument is at a second position on the strap relative to the first wearable instrument.

Abstract: An improved portable solar-powered generator is disclosed herein. Specifically, an improved portable solar-powered generator comprises a plurality of solar panels capable of absorbing and converting photons into direct current energy, wiring attached to solar panels capable of outputting direct current energy from solar panels, and a controller capable of receiving direct current energy by wiring transferred from solar panels, as the controller can be capable of receiving, measuring and distributing the electrical load of the direct current. The improved portable solar-powered generator further comprises a battery receiving direct current energy from the solar panels by way of controller, as the battery can be capable of storing and transferring direct current energy. Additionally, an improved solar powered generator comprises an analog to digital converter capable of converting the direct current energy received from the battery into alternating current.

Abstract: A simplistic low cost circuit that generates the necessary drive voltage for use in a source follower totem pole power switching circuit is described where the simplified gate drive circuit may have a dual charge pump and a complementary pair of low-power switching Mosfets.

Abstract: A device for storing dental floss and paying the floss out is disclosed, which device provides three separately-usable strips of dental floss for use to floss teeth. The three strips form a U-shaped loop, and are tightened, or tensioned, for use by a tensioning means made up of an axle with a slot formed at each end, through which portions of the first and third strips of floss pass, which first and third strips are parallel to each other. The axle is mounted for conjoint rotation with a ratchet wheel which is allowed rotation in only one direction by an associated pawl. A thumb wheel mounted for rotation with the ratchet wheel and axle is rotatable by the user of the device to continually tension the strips of floss for use, which rotation of the thumb wheel is easily done by one hand of the user.
