Abstract: An oral irrigator including a reservoir, a handle, and a tip connected to the handle and in fluid communication with the reservoir. The oral irrigator also includes a base unit including an operating assembly configured to selectively provide a first fluid from the reservoir to the tip. The operating may include, an some examples, a motor and a pump. The oral irrigator further includes a fluid pressure trigger connected to the handle and including a second fluid. Based on a pressure of the second fluid, the fluid pressure trigger closes an electrical contact to the operating assembly causing the operating assembly to selectively vary at least one characteristic of the first fluid flow from the reservoir to the tip.

Abstract: An auto-sensing, automatic adjusting exhaust baffle; for reducing noise emissions produced by internal combustion engines, while improving overall engine performance, i.e., torque and horsepower. The design uses a spherical shape to evacuate spent exhaust gas, thus scavenging the surrounding exhaust gases to adjust the backpressure, while reducing the noise exiting the exhaust pipe at lower rpm's. The device uses a sphere with an internal bearing; sliding linearly on a shaft and said sphere and bearing being acted upon by exhaust gasses and a compression spring mounted axially over the diameter of the shaft. The purpose of this device is to reduce noise while improving tuning of the air/fuel intake system, by adjusting backpressure of the exhaust system. The lesser amount of exhaust pressure, the less the sphere moves, as in idle to just off of idle, this results in a quiet operational mode of the invention.

Abstract: A handle housing that is modular and easily assembled and disassembled for maintenance and cleaning. The handle housing has an integrally-formed orientation shape (e.g. S-shape) to keep it from tipping onto the flossing tip. The handle housing also includes the rocker arm, cam drive (together the drive train), motor, power supply and bobbin for full functionality, with linear, reciprocating motion created by the drive train for effective cleaning.

Abstract: A flosser tip holding cartridge including one or two internal storage rails having a base for supporting the rails upright on a support surface. A housing surrounding and protecting the storage rails and a slot in the front portion of the housing for accessing each rail. A tip removal slot on the top side for facilitating the removal of a flossing tip from the flossing device. Each rail includes a longitudinally-oriented recess having side walls that define a shape that closely receives individual flosser tips for storage and access.
