Embodiments are directed to portable infusion devices, systems, and methods of using the same for dispensing materials. In some cases, the devices, systems and methods may be used for infusing a material such as medicament, e.g., insulin, into a body in need thereof.

Infusion pump system with disposable cartridge having pressure venting and pressure feedback

A dispenser (10) for use with an air-treating composition to be emitted includes a base having a container support and a mounting surface (50) separate from the container support. A container (30) is coupled to the base container support and adapted to receive the air-treating composition, and a diffuser element (26) is coupled to the base and positioned to disperse the air-treating composition from the container into the surrounding environment. A cover (16) is adapted for attachment to the base mounting surface (50). The container support remains intact when the cover (16) is removed therefrom. The cover (16) may include a frame for holding one of a plurality of substrates carrying different images. In addition, the base may be formed of a plastic material while the cover is formed of a ceramic material.

A full coverage fluidic oscillator (2) includes a fluidic circuit member preferably having an oscillation inducing internal chamber, at least one inlet (8) or source of fluid under pressure, at least a pair of output nozzles (14, 16) connected to the source of fluid for projecting at least first and second impinging fluid jets into free space, where the first and second impinging jets collide or impinge upon one another at a selected jet angle to generate a substantially omni-directional sheet jet having selected thickness. The first and second jets are aimed at a pre-selected intersection point in free space where impingement is to occur. The sheet jet's thickness Δy is determined by the time-varying path or oscillation of each of the first and second impinging jets. The first and second impinging jets can be made to oscillate or pulsate by use of vortex generating amplifier structures (68, 70, 72, 149) within the internal chamber's fluid flow paths.

A motorized toilet bowl cleaning device includes a main body having a frame that attaches to a rim of a toilet bowl; a container coupled to the main body capable of holding a cleaning solution; a dispenser coupled to the container to spray the cleaning solution; an electric motor coupled to the main body; at least one brushing arm attached to the main body, a power source for powering the electric motor; and at least one moving wheel driven by a motor such that when the main body is attached to the rim, the wheel is in engaging contact with a surface of the rim. The dispenser is positioned and angled in a manner to spray the cleaning solution onto an inside wall of the toilet bowl.

Toilet bowl self-cleaner

An automatic cleaning assembly having an outer body and an inner lid which, when attached to each other, may define an inner chamber and an outer chamber. Refill water may enter the inner chamber through a fluid flow path of an inlet. A cleaning agent disposed within the inner chamber may be partially dissolved upon contact with the water. The water with the dissolved cleaning agent begins to fill the outer chamber and exit out of the outlet of the automatic cleaning assembly. The outlet of the automatic cleaning assembly is positioned above the inlet of the automatic cleaning assembly such that water is retained within the outer chamber to prevent gas caused by the cleaning agent from escaping into the environment. Moreover, the automatic cleaning assembly may have a check valve to prevent water from back flowing into a ball cock of the toilet.

Automatic cleaning assembly for a toilet bowl

A device for spraying an inner surface of a toilet bowl with a cleaning and/or deodorizing chemical is disclosed. The device includes a container for the chemical, a spray nozzle through which the chemical can be sprayed laterally around a perimeter of the nozzle, a conduit in fluid communication with the container and the spray nozzle, fluid delivery means for delivering chemical from the container through the conduit and to the spray nozzle, and means for attaching the spray nozzle near a rim of the toilet bowl. The spray nozzle of the automatic or manual toilet bowl cleaning device can operate such that the chemical is applied to the entire circumference of the inner surface of the toilet bowl whereby the entire toilet bowl is cleaned around the inner circumference of the toilet bowl.
