Abstract: A humidification system can include a heater base, a chamber, and a breathing circuit. The heater base includes a heater plate positioned in a recessed region, and a heat conductive portion of the chamber is configured to contact the heater plate. The heater base includes a guard configured to control movement of the chamber into and out of the recessed region. The guard includes an anti-racking mechanism. The chamber includes an inlet port, an outlet port. A downward extension extends into the chamber from the inlet port, and a baffle is disposed at a lower end of the downward extension. A component of the breathing circuit can include a conduit hanging end cap for shipping and storage. The end cap can include a hanging component to allow the breathing circuit component to be hung from a medical stand. The system can detect when breathing circuits are connected in reverse.

Abstract: A Reconfigurable, Flexible Multi-User (RFMU) electronically steered antenna (ESA) includes a top panel and a number of side panels that enable many contacts simultaneously with varying gain requirements from a single, in situ, installation. The top panel includes multiple subarrays and can communicate with flyover satellites, and the side panels can communicate with satellites flying past a side of the ESA. The top panel and the side panels can achieve a beam steering that covers a full or partial, variable gain, hemispheric field-of-view (FoV). The RFMU ESA terminal top and side panels are scalable using flexible modular building blocks. This enables increased contacts, increased gain or a combination thereof sized to meet desired performance.

Abstract: A rotary device includes a shaft, a rotor coupled to the shaft, and a stator having a cam surface. Vanes reside within slots of the rotary device and engage with the cam surface. A first seal couples to the rotor and includes first grooves that extend in a direction substantially parallel to a rotational axis of the shaft. A second seal couples to the stator and includes second grooves extending in the direction substantially parallel to the rotational axis. A third seal couples to the rotor and includes third grooves extending in the direction substantially parallel to the rotational axis. A fourth seal couples to the stator and includes fourth grooves extending in the direction substantially parallel to the rotational axis. The first grooves and the second grooves, as well as the third grooves and the fourth grooves, from labyrinth seals for the chambers of the rotary device.

Abstract: A modified two-phase refrigeration cycle compresses a working fluid, condenses the working fluid into a saturated or supercooled liquid, expands the saturated or supercooled liquid into a two-phase fluid, and evaporates the two-phase working fluid. The modified two-phase refrigeration cycle reduces irreversibilities imposed by conventional refrigeration cycles and extracts energy from the working fluid during the expansion process. For instance, a system that employs the modified two-phase refrigeration cycle includes a two-phase expander to reduce irreversibilities during an expansion process and extract energy. In some instances, the system includes a two-phase compressor to compress two-phase fluids for varying loads and environmental conditions of the system.

Abstract: Described herein are methods of determining energy balance in individuals such as exercising individuals, individuals consuming a 13C-enriched test composition and individuals consuming a fixed diet with a known ?13C. The ?13C pre- and post-exercise, or pre- and post-consumption of the test beverage or fixed diet indicate whether the individual is in neutral or positive energy balance, or in energy deficit. The methods are particularly useful for individuals participating in weight management programs, and individuals under the care of health care professionals.
