Abstract: A heating, ventilation, and air-conditioning (“HVAC”) system. The HVAC system may include a refrigeration circuit and a blower system. The refrigeration circuit may include a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger. The blower system may include a first direct-drive blower and a second direct-drive blower. The first direct-drive blower may flow air over the indoor heat exchanger. The second direct-drive blower may flow air over the indoor heat exchanger and the second direct-drive blower may operable and positionable relative to the indoor heat exchanger independently from the first direct-drive blower.

Abstract: A heat exchanger cabinet includes a base pallet. A heat exchanger base bracket of a selected fixed height or of an adjustable height bracket provides a support for a bottom of a heat exchanger, such that regardless of a height the heat exchanger, and within a range of different heat exchanger heights, a plurality of top mounted fluid inlets and outlets of the heat exchanger are disposed at about a same height above the base pallet. A set of heat exchanger base brackets, a stackable heat exchanger base bracket, a heat shield for a heat exchanger cabinet, and a heat exchanger cabinet for a vertically mounted heat exchanger are also described.

Abstract: A venous air capture chamber for use in dialysis, includes an upwardly extending fluid inlet terminating in first and second fluid inlet ports (102). The first and second fluid inlet ports (102) are opposedly positioned on the fluid inlet at an angle of about 180°. The venous air capture chamber also includes a fluid outlet (104) at the bottom of the chamber body. The venous air capture chamber provides improved fluid dynamics, reducing both stagnant flow and turbulence. The venous air capture chamber also provides for bidirectional flow of fluid through the chamber.

Abstract: A fuel-fired heater can include a fuel tank; a housing assembly supported by the fuel tank, the housing assembly defining a chamber having an inlet and an air outlet; a fan located within the housing assembly; an air pump located within the housing assembly; an electric motor coupled to at least one of the fan and the air pump; a burner assembly located within the housing assembly, the burner assembly including a burner nozzle in fluid communication with the air pump and the fuel tank via a fuel line, and including an ignitor; and an electronic controller operating the electric motor and ignitor, the electronic controller including a proximity sensor oriented and arranged to sense an object located in front of the air outlet, wherein the electronic controller deactivates the electric motor when an object is sensed by the proximity sensor within a predetermined distance for a predetermined time period.

Abstract: The present invention is directed to a composition that includes an amphiphile, its use in a method of preventing and/or treating cancer, and its use in a method of producing a pharmaceutical composition. In certain embodiments, the amphiphile includes a hydrophilic peptide that binds to a Plenty of SH3 domain (POSH) and inhibits or disrupts a POSH scaffold network, a hydrophobic moiety, and an aptamer. The present invention is also directed to other POSH inhibitor complex biomolecules that do not contain a hydrophobic moiety.

Abstract: A water heater includes a heat exchanger. A controllable three-way proportional valve provides a proportionally controllable flow to the hot water inlet of the heat exchanger and a boiler return water outlet. A mixing tank mixes a cold water and a hot water. The mixing tank provides a time delayed mixed water. A temperature sensor is disposed in or on the mixing tank to measure a temperature of the time delayed mixed water to provide a time delayed mixed water temperature. A feedforward control process running on a processor adjusts a proportional operating position of the controllable three-way proportional valve to regulate a temperature of hot water at the hx domestic hot water outlet based on the temperature of the time delayed mixed water temperature. A method for controlling a hot water temperature of a water heater a water heater using a flowmeter based feedforward control are also described.
