Abstract: The present invention provides new devices, systems, and methods for delivering enriched oxygen to recipients (e.g., chronically ill patients, such as COPD patients). One aspect is a more efficient portable oxygen concentrator that is configured to deliver an enriched oxygen airflow having a significantly lower overall oxygen concentration and greater overall volume administered as compared to currently marketed or known portable oxygen concentrators. Administering the lower oxygen concentration at higher volumes allows for the present portable oxygen concentrators to deliver an equivalent number of moles of oxygen as administered by traditional portable concentrators while increasing the efficiency of the system and the ability of the system to maintain the therapeutic level of oxygen concentration for a longer period.

Abstract: The invention provides new systems/methods for providing oxygen to chronically ill patients, such as COPD patients, through a more efficient portable oxygen concentrator (“POC”) that at least sometimes delivers an enriched airflow having a significantly lower overall oxygen concentration than that administered by typical POCs. In aspects, the methods/systems of the present invention are configured to automatically switch from pulse delivery to continuous delivery, from continuous delivery to pulse delivery, or any combination thereof, at least once per day, when certain conditions occur. Methods/system can comprise the ability to switch between mode(s) comprising delivery of a moderately enriched oxygen airflow (MEOA) and mode(s) comprising delivery of intensively enriched oxygen airflow, highly enriched oxygen airflow, or both, and back again, based on one or more parameters.

Abstract: A portable washbasin system for providing clean water for washing hands and maintaining appropriate hygiene, the system including a housing structure with an upper compartment and a lower compartment spaced apart from one another, and a sink supported on the housing structure between the upper and lower compartments. A water storage tank is housed in the upper compartment, where the sink receives water from the water storage tank and dispenses the water for use. The system further includes a water receptacle housed in the lower compartment for collecting wastewater from the sink for subsequent disposal.

Abstract: The invention described herein provides new devices suitable for effectively converting temperature differences, including relatively low temperature differences, into useful work (e.g., for generating electrical power), related systems, and methods of using and developing such devices/systems. The devices are characterized in, inter alia, comprising an at least partially enclosed moveable component (e.g., a piston), an enclosed/isolated pressurized gas, and an enclosed temperature modifying liquid or energy transfer fluid system having portions which obtain temperature characteristics from two sources, which portions are alternatingly dispensed (e.g.

Abstract: The disclosure relates to a portable waste collection and sanitation system designed to handle liquid and solid waste, and while conserving water and minimizing odors. The sanitation system is also designed with modular components adapted for in-home installation, where the system can be quickly disassembled and relocated as needed, such as for moving the components to a new location based on environmental conditions.

Abstract: The invention described herein provides new devices suitable for effectively converting relatively low temperature differences into useful work (e.g., for generating electrical power), related systems, and methods of using and developing such devices/systems. The devices are characterized in, inter alia, comprising an at least partially enclosed moveable component (e.g., a piston), a closed pressurized gas system comprising sizeable void spaces, and a closed temperature modifying liquid system having portions that obtain temperature characteristics from two sources, which are alternatingly dispensed as droplets into the pressurized gas, creating a pressure/temperature difference in the gas which causes the moveable component to move back and forth along a stroke distance that does not include the void spaces, the pressure of the gas and liquid being at substantially balanced when the device is ready for operation.

Abstract: An electrical equipment cabinet has a standby battery to supply current when a mains connection is not available. In normal operation the battery is maintained charged by the mains supply. In order to test the condition of the battery, a measuring system is arranged to operation in co-operation with a test of a residual current detection device, which temporarily disconnects the mains supply, thus measuring the condition of the battery, when under load.

Abstract: An apparatus sizes an exhaust component that includes an outer shell that surrounds first and second substrates. At least one sensor hole is formed in the outer shell at a location between the first and second substrates. A first end of the outer shell is surrounded with a plurality of first fingers to size the first end around the first substrate to a first cross-section. At least one first finger has a protruding portion at a first finger distal end that is longer than first finger distal ends of the other first fingers. A plurality of second fingers surrounds the second shell end to size the outer shell about the second substrate to a second cross-section. At least one second finger has a recess portion at a second finger distal end that receives the protruding portion of the at least one first finger.
