Abstract: Therapy patches are disclosed which are designed to deliver vibration and heat (or cold) to human skin so as to provide muscle relief. These patches have a chemical pouch that generates heat or cold upon initiation. They also have a motor and battery to provide a vibration source. Forms of the invention have an adhesive so that the patch can be attached to the skin (and thus need not be manually held in place during use). Kits are also provided in which the motor and battery can be used with a string of linked, severable replacement pouches. Methods of using these patches are also disclosed.

Abstract: A sprayer is disclosed that may be attached to a garden hose for cleaning exterior surfaces such as windows. By turning a flow selector in a single direction tap water from the hose first flows through the sprayer to rinse the surface to be cleaned. The flow selector can then be set to spray a mixture of cleaner (e.g., one or more surfactants) and surface modifier (e.g., one or more polymers) and water on the surface. The flow selector can then be set to an off position to allow for scrubbing of the surface with a scrubbing tool. The flow selector can then be set to rinse the surface with untreated water, and the flow selector can be turned further to rinse the surface with filtered tap water produced by a filter in the sprayer. Also disclosed are unitary cartridges providing a combined replacement of the cleaning surfactant and a filtering system for deionizing the water.

Abstract: A manual advance floss holder which is simple and inexpensive to construct, comfortable to grasp, convenient to use in one hand and presents floss for flossing under uniform and proper tension while protecting the supply of unused floss from contamination including a body with a fork located at its distal end, a floss control mechanism within the body of the manual advance floss holder, a floss control mechanism including supply and take-up reels and means for advancing the floss therebetween under tension, and different compartments within the body for isolating spent and fresh floss.

Abstract: A method and apparatus for detecting a restricted or bypassed transmission oil filter by providing pressure transducers on both sides of the oil filter whereby the pressure differential will indicate the extent of filter restriction. A first alarm is activated at a first pressure differential to indicate a restricted filter and the need for filter replacement. A second, higher level, alarm is activated to indicate the filter is bypassed and the engine is reduced in speed to allow the pressure and the pressure differential to drop to the point that the filter is no longer bypassed. This enables the vehicle to be operated with limited capabilities to allow the vehicle to be driven to the shop for filter replacement. If the lowered engine speed is insufficient to reduce the pressure differential to stop the bypass, then the engine speed is further reduced to a low idle and the transmission shifted to neutral.
