Electrical leads are placed in the channel. A lens is inserted into the channel over the leads. A replaceable LED module having a circuit board secured to a module base is attached to the leads. The circuit board preferably has a gasket or seal, an LED and two contact teeth that make electrical contact with the leads.

Abstract: The present invention is a soft light fixture. In particular, it is an LED soft light fixture. The preferred embodiment of the soft light fixture has a plurality of light emitting diodes mounted on a perimeter ring aimed to emit light into a light-mixing chamber. The perimeter ring supports a light deflection cap with a lens, preferably translucent. The ring, deflection cap and lens define the light mixing chamber which blends light from the plurality of light emitting diodes into a single light source.

Abstract: The present invention is a ground-embedded, air-cooled lighting device. In particular, the present invention is directed to a floodlight or sealed lamp. A preferred embodiment of the floodlight comprises a sealed casing having an exterior wall and contains air. The sealed casing holds a disc element supporting a translucid material and a tube spaced from the exterior wall. The tube is preferably concentrically mounted within the casing. The tube surrounds an optical reflector, a light source mounted at the reflector's focus and aimed at the disc element, and a power supply for the light source. The sealed casing further contains a fan, preferably aimed a portion of the exterior wall having increased thermal conductivity. The fan circulates air in the casing through the tube and past the disc element for cooling purposes.

Abstract: The present invention is an improved earpiece light. In particular, the present invention is directed to an earpiece having a power supply and a light source mounted on the earpiece. The earpiece light is preferably for use on a person's outer ear. The earpiece light comprises an ear support, preferably for placement behind the user's crest of helix. The ear support is attached to a power supply housing, preferably for placement over the user's external auditory canal. The power supply housing has a power supply and a lamp arm with a distal end extended from the power supply housing. The power supply is connected to a light source mounted on the distal end of the lamp arm. Preferably, the lamp arm is positioned below the ear support and the power supply is connected to a light source, preferably an LED, mounted on the lamp arm.

Abstract: The present invention is an intrinsically safe pneumatically actuated flow controller. A preferred embodiment for the flow controller has a housing assembly defining an inlet port, an outlet port, a pressure signal inlet port, and a main flow path extending between the inlet port and the outlet port. A restriction member is arranged in the main flow path. A first valve assembly and second valve assembly control fluid flow along the main flow path. A first regulator assembly operates the first valve assembly. A pressure signal actuation assembly has an actuation bellows attached to an actuation piston mounted on a flow control piston rod that passes through an isolation plate and is sheathed by an isolation bellows. The flow control piston rod terminates in a flow control piston that engages a second regulator assembly, which operates the second valve assembly based on pressure signals transmitted through the pressure signal inlet to the pressure signal actuation assembly.

Abstract: The present invention generally relates to a lighting fixture where individual light sources can be removed and/or replaced from a strand of light sources. The preferred embodiment of the light fixture comprises a plurality of light sources strung together by a plurality of wire assemblies. Each light source preferably has one end of a tongue and groove connector where the opposing end of the connector is attached to an end of a wire assembly.

Abstract: A flow controller having a first and second stages of regulation. The first stage is a pressure regulation stage that maintains the pressure within an intermediate chamber (formed by a series of interconnected passageways and cavities) within a predetermined range above the pressure in an outlet port. The second stage maintains the flow rate within a predetermined range about a target flow rate. Both stages sample the pressure in the outlet port and automatically adjust the flow of fluid to ensure that fluctuations in pressure at the inlet and outlet ports do not affect the flow rate. The flow rate is set and controlled by a user determined setpoint. The pressure is regulated by one or more feedback systems. The feedback systems used may be mechanical or electromechanical based on a particular operating environment.

Abstract: A flow meter system that calculates mass flow rate based only on a single pressure signal. A flow controller is arranged in parallel with a restriction such that it constant pressure differential is maintained across the restriction. The pressure, and temperature if not controlled, of the fluid flowing through the restriction is measured on either side of the restriction. The pressure is compared to a plot of pressure versus mass flow rate calculated for the specific restriction and fluid being measured. The constant pressure differential maintained across the restriction yields a linear relationship between pressure and flow rate. If temperature is not controlled, the plot or pressure versus mass flow rate will remain linear, but the slope of the curve will be adjusted based on the temperature of the fluid.
