Abstract:
An embodiment of a system for treating sleep apnea includes a collar, a pump, and a motor. The collar has a vacuum surface and has a sealing surface that is configured to form a seal with a region of a neck of a subject having an airway. The pump is secured to the collar, and is configured to maintain the airway open by drawing a vacuum between the vacuum surface of the collar and a region of a throat of the subject. And the motor is secured to the collar and is configured to drive the pump. As compared to existing systems (e.g., a Continuous Positive Airway Pressure (CPAP) system) for treating sleep apnea, the above-described system may be more portable, more comfortable, may be less likely to require adjustment while a subject using the system is asleep, and, therefore, may be less likely to awaken the subject.

Abstract:
An apparatus comprising a device suitable for retention in a nasal passage of a ruminant, the device is arranged to pass a ruminant exhalation. The device includes a first structure configured to oxidize methane gas in the ruminant exhalation and to pass products of the oxidized methane gas toward a nasal passage exit.
Abstract:
A system is described generally for a water capture structure that is configured to capture wave water lapping over at least one wall of the water capture structure. The at least one wall extends at least above a nominal surface water level and at least one conduit extends downward from the water capture structure. The at least one conduit has a length extending to a depth at which at least one property of water at the depth differs substantially from that of water at the surface. The at least one conduit is configured to provide thermal energy to water outside of the at least one conduit. The at least one conduit has at least one conduit wall.

Abstract:
A system is described generally for providing a structure or structures for altering water surface temperature. The system includes a holding vessel configured to hold water. The holding vessel has at least one wall coupled to a lowermost portion. The at least one wall extends above the water level and the lowermost portion is configured to be submerged. At least one conduit extends from the lower side of the holding vessel. The at least one conduit has a length extending to a depth at which a property of water at the depth is substantially different from that of the water at the surface.
Abstract:
Methods and articles are provided for reducing the amount of water consumed by a plant over a period of time, sequestering CO 2 , and producing electricity, where each method includes providing the plant with a composition including at least about 0.1 (wt./wt. or vol./vol.) % CO 2 and/or at least about 0.1 wt./wt.% of a composition that generates CO 2 . An apparatus is also disclosed for providing the plant with a composition including CO 2 and/or a composition that generates CO 2 .
Abstract:
A dryer including a housing, a drying chamber disposed within the housing, and a heating element coupled to the housing. The dryer further includes an intake configured to supply intake air to the drying chamber and an exhaust vent configured to vent exhaust air out of the drying chamber. The intake, the drying chamber, and the exhaust vent define an air flow path from the intake through the drying chamber and out the exhaust vent. The dryer includes a heat exchanger and a heat pump having a condenser. The heat exchanger and the heat pump are each configured to absorb thermal energy from the exhaust air and transfer the thermal energy to the intake air. The air flow path is configured such that the intake air is heated directly or indirectly by the heat exchanger prior to the intake air being further heated directly or indirectly by the condenser. The air flow path is configured such that the intake air is further heated directly or indirectly by the condenser prior to the intake air entering the drying chamber.
