Abstract: A boiler system and methods of operating the system are disclosed. The boiler system, which converts a cryogenic liquid to its gas phase, may be used in various types of space vehicles for various types of missions. Among other sources, the system principally operates using waste heat that is invariably produced during the many functions and processes that occur during space flight. Waste heat may be collected and applied to a heat exchanger in a recirculating loop that includes a boiler tank, where the cryogenic liquid is resultantly heated to a gas, which may be subsequently used or collected in one or more accumulator tanks, for example. If waste heat is used in this liquid-to-gas conversion process, the boiler system consumes relatively low amounts of energy produced by, or stored in, a space vehicle.

Abstract: Architectures and methods of operation for a pump for pumping two-phase magnetic fluids are described. The pump is capable of such pumping and may operate with no moving parts. Instead, the pump operates by selectively activating and deactivating each of a series of electrical circuits to control the presence or absence of magnetic fields applied to the two-phase magnetic fluid. The two-phase magnetic fluid may include liquid phase and gas phase, which may be in the form of bubbles. Though a presence of bubbles in a liquid may lead to cavitation and failure in some pumps, pumps for pumping two-phase magnetic fluids can avoid such a failure mechanism, in addition to avoiding another failure mechanism of wear and tear on moving parts.

Abstract: A medical appliance for the treatment of one or more sleep disorders such as obstructive sleep apnea in a patient, the appliance comprising: a biasing member for inserting behind and exerting a force upon the patient's soft palate or tongue, wherein the biasing member is inserted in a reduced or minimized form and then expanded or firms once in place to exert the force. The appliance may be nasally inserted or be placed through the mouth. In a particular configuration, both the soft palate and tongue are biased to prevent obstruction of the flow of air in the nasopharyngeal airway.

Abstract: A boiler system and methods of operating the system in a low-gravity environment are disclosed. The boiler system, which converts a cryogenic liquid to its gas phase, may be used in various types of space vehicles for various types of missions. The system principally operates using waste heat that is invariably produced during the many functions and processes that occur during space flight. The waste heat is collected and applied to a boiler tank in the system, where the cryogenic liquid is resultantly heated to a gas, which may be subsequently used or collected in one or more accumulator tanks, for example. Because waste heat is used in this liquid-to-gas conversion process, the boiler system consumes relatively low amounts of energy produced by, or stored in, a space vehicle.

Abstract: Techniques and systems involve a magnetically enhanced cryogenic boiler that produces, without requiring pumps, high pressure gaseous oxygen from liquid oxygen for use in a spacecraft or other applications. The boiler heats, using a heat exchanger element, a closed container of liquid oxygen to boil the liquid oxygen at constant volume and increasing the pressure in the container. When a desired target pressure is reached, the boiler may release and transfer the high pressure fluid into a gaseous oxygen accumulator for storage. Magnets may be used to draw low pressure liquid oxygen into the boiler and to keep the liquid oxygen on or near one or more heat exchanger elements in the boiler, by exploiting paramagnetism of oxygen. The magnets produce a magnetic field that maintains relatively strong thermal contact between the heat exchanger elements and the liquid oxygen, even in the absence of gravity.

Abstract: The present disclosure relates to methods for predicting time-to-delivery in pregnant women. The methods include predicting that a pregnant woman will deliver within a predetermined time frame if PAMG-1 is determined to be present at a level above a predetermined detection threshold in a vaginal fluid sample obtained from the pregnant woman. Also provided are methods for determining a patient's risk of preterm labor and/or spontaneous rupture of the chorioamniotic membrane.

Abstract: A drug delivery device includes a housing, a drug delivery assembly disposed within the housing along a longitudinal axis, and a cap defining a shell. At least one electronic component, a power source, and a switch assembly are at least partially disposed in and coupled to the cap. The switch assembly is movable along a plane orthogonal to the longitudinal axis of the drug delivery assembly to cause the power source to provide power to the electronic component. The device further includes an activation mechanism at least partially disposed in the cap. Upon urging the cap along the longitudinal axis in a direction away from the housing, the activation mechanism engages the switch assembly and causes the switch assembly to move, thereby causing the power source to provide power to the at least one electronic component.
