Electrical components and vacuums. In some aspects, the invention provides an electrical component including a housing defining a passageway, a motor supported by the housing, the motor being selectively electrically connectable with a power source, a fan connected to the motor and operable to generate an airflow through the passageway, an electrical circuit supported by the housing, the electrical circuit being selectively electrically connectable with the power source, and a power-tool battery electrically connectable with the electrical circuit such that power is selectively transferred between the battery and the electrical circuit, the battery being connectable to the housing. In some aspects, the invention provides a vacuum.

An electronic cigarette has two tubes that resemble a cigarette: an electronic inhaler and an electronic atomizer. The two tubes are connected through one or more electric connectors to form an electronic cigarette. Inside the inhaler is a rechargeable or non-rechargeable power source such as a battery, which supplies electric power to the electronic inhaler and atomizer and ensures that both work together like a cigarette. In addition to the power source, the inhaler also includes other major components: an electric airflow sensor to detect air movement generated by a user's inhaling or puffing act and a Single Chip Micyoco which controls the atomization process. The sensor's role is to collect an airflow signal that triggers the Single Chip Micyoco, which in turn instructs the electronic cigarette to supply electric power to the inhaler and atomizer connected through an electric connector. Inside the electronic atomizer are an electric connector, electric heating wire, liquid container, and atomizer cap with an air-puffing hole. The user inhales through the air-puffing hole at an end of the electronic cigarette to create an air inflow, which triggers the atomization process. The Single Chip Micyoco driven by a software program controls the electronic cigarette in an on / off manner according to the signal detected by the electric sensor on the airflow and completes a cycle of atomization, which converts a solution of a liquid form inside the liquid container to a gas form. This entire process achieves the emulated smoking process of a user, who is satisfied with scent taste that mimics cigarette smoking.

An exhaust port assembly comprising a conduit carries a flow of gas. A vent assembly having a fixed exhaust area is provided on the conduit for venting a flow of exhaust gas from within the conduit to ambient atmosphere. The vent assembly is configured so as to minimize noise associated with the flow of exhaust gas passing to atmosphere, diffuse the flow of exhaust gas passing to ambient atmosphere over a relatively large area, and minimize the area occupied by the venting assembly on the conduit.

A system for applying suction to a wound uses a reference airflow for monitoring system operation. A reference airflow (or “controlled leak”) to the suction source is provided when the system is in operation, such that deviation from the reference airflow can be monitored as an indication of a change in operation, such as a leak in the seal of the wound cover, a blockage of airflow from crimping of the suction conduit or overfill of the waste collector, or an inadvertent turn off or disconnect from the suction source.

Embodiments of the present invention generally provide apparatus and methods for supporting a gas distribution showerhead in a processing chamber. In one embodiment, a gas distribution showerhead for a vacuum chamber is provided. The gas distribution showerhead comprises a body having a first side and a second side opposite the first side, and a plurality of gas passages formed through the body, the gas passages comprising a first bore formed in the first side that is fluidly coupled to a second bore formed in the second side by a restricting orifice, and a suspension feature formed in the first bore of at least one of the gas passages.
