An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

A breathing system includes a tank for pressurized breathing gas, at least one regulator comprising a connection to which the tank is attachable, a universal air connector in fluid connection with the connection, and at least one light source, the light source, when illuminated, providing a guide to connect a connector in fluid connection with a secondary tank to the universal air connector to supply breathing gas to the tank.

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

A plumbing fitting includes a housing and a missing valve. The housing includes a first aperture, a second aperture, a third aperture, and a mixing chamber in fluid communication with the first aperture, the second aperture, and the third aperture. The mixing valve is disposed within the housing. The mixing valve includes a first flow control valve that is configured to control a first flow of fluid from the first aperture to the mixing chamber.

An electrical module for use within a fuel injector for delivering fuel to an internal combustion engine is described. The electrical module has a variable length. The electrical module comprises electrical contacts for operatively connecting the electrical module to a power plug of a fuel injector. The electrical module also comprises an actuator for operatively controlling a control valve disposed within the fuel injector. The electrical module also comprises electrical conductors arranged within a protective housing. These electrical conductors provide an electrical connection between the electrical contacts and the actuator in order to provide electrical power to the actuator when the electrical contacts are operatively connected to the power plug of the fuel injector. The body of the electrical module is comprised of a compressible elastic element, such that the length of the module is variable by compressing the elastic element. Injectors including such electrical modules are also described.

An assembly for adjusting gas flow patterns and gas-plasma interactions including a toroidal plasma chamber. The toroidal plasma chamber has an injection member, an output member, a first side member and a second side member that are all connected. The first side member has a first inner cross-sectional area in at least a portion of the first side member and a second inner cross-sectional area in at least another portion of the first side member, where the first inner cross-sectional area and the second inner-cross-sectional area being different. The second side member has a third inner cross-sectional area in at least a portion of the second side member and a fourth inner cross-sectional area in at least another portion of the second side member, where the third inner cross-sectional area and the fourth inner-cross-sectional area being different.

The fuel flow rate to a gas turbine is measured using an inert gas. The inert gas is injected into the fuel flow and the concentration of the inert gas in the fuel/inert gas mixture is later measured. The concentration of the inert gas in the fuel/inert gas mixture is then used to calculate the mass flow rate of the fuel.

A shower control system includes a water subsystem, a steam subsystem, and a controller in communication with the water subsystem and the steam subsystem. The water subsystem includes one or more electronic valves configured to control a flow rate and a temperature of water dispensed from one or more shower outlets within a shower enclosure. The steam subsystem is configured to generate and dispense steam from one or more steam outlets within the shower enclosure. The controller is configured to control the water subsystem and the steam subsystem to provide a spa experience including a predetermined and coordinated sequence of water outputs from the shower outlets and steam outputs from the steam outlets.

A pet drinking fountain assembly having a pump forming part of a fountain mounting arrangement that includes a lift tube coupling a cover to the pump coupled to a lower basin by a mount. The mount and lift tube attenuate pump noise and vibration by providing isolation from the basin and cover and can function as dampeners. In a preferred embodiment the pump is part of a pump module that includes a module housing to which the pump is attached by another noise-attenuating mount. Each mount is formed by one or more suction cups with the cups and lift tube made of vibration dampening material, such as a resilient vibration dampening or isolating material that can be an elastomeric material. The module includes a lift tube coupling discharge that registers in fluid flow communication with a pump outlet and can include a ring or bushing therebetween providing additional noise attenuation.

A mixing valve includes a mixing chamber, a first flow control valve having a first flow control opening, and a second flow control valve having a second flow control opening. The first and second flow control openings each have a diameter of approximately six millimeters and the mixing valve has a flow coefficient of approximately 2.5 when both flow control valves are in a mid-open position.
