Abstract: A rooftop air conditioning unit (RTU) is disclosed. The RTU comprises an absorber configured in a supply airstream, a desorber configured in a regeneration airstream, wherein the desorber is fluidically connected to the absorber via a liquid desiccant system and an interchange heat exchanger. The RTU further comprises a first heat exchanger configured upstream of the absorber in the supply air stream, a second heat exchanger configured upstream of the desorber in the regeneration airstream, wherein the first heat exchanger is fluidically connected to the second heat exchanger via a vapor compression system, and one or more secondary heat exchanger configured between the vapor compression system and the liquid desiccant system, wherein the one or more secondary heat exchangers are operable to control temperature of a desiccant associated with the liquid desiccant system into the absorber and/or into the desorber.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a housing, a plurality of compressors, a condenser, a reheater, and an evaporator arranged in fluid communication. The condenser and the reheater are arranged in parallel and the plurality of compressors are arranged in parallel. A fluid management system is operable to actively manage a flow of a fluid within the HVAC system provided to the reheater.

Abstract: A waist belt for load bearing applications, comprising a downward facing conically shaped sacral plane fitter segment having a first and second ends, the sacral plane fitter segment being configured so as to rest on the sacral region of the lower back of a wearer, a first sub-iliac crest segment issuing from the first end of the sacral plane fitter segment and a second sub-iliac crest segment issuing from the second end of the sacral plane fitter segment the first and second sub-iliac crest segments being configured so as to rest on the sub-iliac regions of the pelvic bone and a first abdominal relief cut segment issuing from the first sub-iliac crest segment and a second abdominal relief cut segment issuing from the second sub-iliac crest segment, the first and second abdominal relief cut segments being configured so as to curl under the abdomen.

Abstract: An ear canal flushing device includes a main body with a cavity for storing a liquid and a temperature sensor for indicating when the liquid is within a selected temperature range that will not adversely affect the patient when the liquid contacts the tympanic membrane. A nozzle is removably attachable to the main body where the nozzle includes a distal portion adapted for insertion into the ear canal and an internal nozzle lumen in fluid communication with the opening in the main body. The nozzle also includes at least one discharge port in fluid communication with the internal nozzle lumen wherein when pressure is applied to the main body a volume of the cavity decreases and liquid is forced out of the at least one discharge port such that the ear canal can be rinsed.

Abstract: A port for providing access to a surgical site in a patient's body includes a plurality of segments that when positioned substantially adjacent to each other form a substantially uninterrupted outer perimeter and an internal access portal to the surgical site The port also includes a locking mechanism for retaining the plurality of segments substantially adjacent to each other.

Abstract: A hemostatic sealing assembly comprises a valve housing and a two-stage hemostatic gasket. The gasket is disposed in an enlarged recess within a shell component of the housing and held in place by a terminal plug. The front and rear faces of the gasket are conically tapered as are the mating surfaces and the housing shell and terminal plug, respectively. In this way, the gasket can be radially compressed to provide a desired degree of both sliding seal and static seal.
