A common mode choke apparatus includes a first bus bar forming a first plurality of loops about a first segment of a ferrite core, the first bus bar having a plurality of first upper surfaces, and a second bus bar forming a second plurality of loops about a second segment of the ferrite core, the second bus bar having a plurality of second upper surfaces.

A wireless speaker system may include a primary speaker including a first transceiver and a second transceiver and programmed to receive audio data from a user device at the first transceiver, and at least one secondary speaker including a receiver and programmed to receive a wireless signal including the audio data from the primary speaker at the receiver, each speaker configured to transmit audio signals consistently there between based on the received audio data.

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.

A fiber optic transducer is provided for use in remote monitoring of the position of mechanical devices, such as the position of valves used in the petroleum and chemical industries and the like. The fiber optic transducer includes a transducer frame supporting an optical fiber under conditions of predetermined bending and tension. Cam apparatus is coupled between a mechanical device to be monitored and a bending pin having a cylindrical surface bearing against the fiber to control further bending thereof in response to position changes of the mechanical device. Changes in light transmission through the fiber as a result of bending can be detected and correlated with the position of the mechanical device.

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. The axle is readily removable from the thumb wheel and ratchet wheel, and is rotatable with them by a non-circular part formed in the central portion thereof, which non-circular part mates with the non-circular openings in each of the thumb wheel and ratchet wheel.
