Abstract:

Methods and apparatus for evaluating the quality of an environment or process by measuring light emitted from a bioluminescent sample containing ATP, ADP, or alkaline phosphatase. The apparatus comprises a sample collection and analysis system used to collect a sample, mix reagents, react the sample, and collect it in a measurement chamber. The system includes an instrument having a photon detection assembly for use with the sample testing device and one or more probe assemblies that optically cooperate with the instrument. The instrument includes a dark chamber with a reflective interior surface which may be concave or preferably spherical, and a photon detection sensor such as a multi-pixel photon counter sensor. A substantially transparent portion of the probe assembly, and liquid contained therein, focus bioluminescence toward the photon detection sensor.

H05B 6/10
B05B 11/02

Abstract:

In various embodiments, a fluid delivery pod includes a first surface, a second surface that opposes the first surface, a reservoir body, an outlet port, a heating structure, and a valve assembly. The reservoir body is between the first and the second surfaces. The reservoir body is configured to house a fluid. The outlet port is positioned on a surface of the pod. The surface is between the first and the second surfaces. The heating structure is thermally coupled to the fluid housed within the reservoir body. The heating structure wirelessly receives energy from an energy source that is external to the fluid delivery pod. The wirelessly received energy heats the fluid housed within the reservoir body. In response to an application of compression forces on the first and the second surfaces, the valve assembly dispenses the heated fluid through the outlet port and out of the fluid delivery pod.

Abstract:

A portable device heats a fluid within a reservoir. The device includes a housing, a cavity, and an energizing element. The housing includes a first longitudinal end, a second longitudinal end, and outer surfaces of the device. The outer surfaces extend from an outer portion of the first longitudinal end to an outer portion of the second longitudinal end. The cavity extends from a cavity port that is positioned on an inner portion of the first longitudinal end to a cavity terminal positioned intermediate the first and second longitudinal ends. Inner lateral surfaces are adjacent the cavity and extend from the inner portion of the first longitudinal end to an outer portion of the cavity terminal. The energizing element is around the cavity. The cavity is positioned intermediate a first energizing element portion and a second energizing element portion. The energizing element provides energy to the cavity.

International Classification:

B05C 5/00

Abstract:

A fluid reservoir includes a reservoir body, a heating structure, a piston, and an outlet port. The reservoir body includes a cross section, and a translation axis. The cross section is uniform along the translation axis. When fluid is housed in the reservoir, the heating structure is thermally coupled to the fluid. The heating structure energizes the fluid housed in the reservoir. The piston translates along the translation axis. An available volume of the reservoir to house the fluid is defined by a distance between the piston and an end of the reservoir body. When the piston is translated along the translation axis toward the end, a volume of the fluid that has been energized by the heating structure flows from the reservoir and through the outlet port. The volume of energized fluid is linearly proportional to a length of the translation of the piston.

International Classification:

B67D 3/00

Abstract:

A dispenser includes a housing, an aperture, a receptacle, a heating element, and an actuator. When a reservoir is received within the receptacle, an outlet port of the reservoir is exposed through the aperture. The heating element heats fluid housed within the reservoir. The actuator provides a dispensing force that induces a flow of the heated fluid. In some embodiments, the heater is an inductive heater. In other embodiments, the heater is a resistive heater. The dispenser dispenses the fluid through the aperture. Another embodiment of a dispenser may include a housing, an aperture, a receptacle within the housing, an actuator configured to receive a fluid reservoir, and a power source. The power source provides power to the actuator. The power source includes an alternating current source.
