Abstract: A thermoelectric power generation system includes a solar panel array on a first side of a tower to absorb solar radiation and generate electrical energy and waste heat and a panel on a second side, opposite the first side, of the tower. A plurality of thermoelectric elements of the tower are interposed between the solar panel array and the panel. The plurality of thermoelectric elements converts conductive heat flow of the waste heat from the solar panel directed toward the panel to electrical energy. A conductive base supports the tower and to conduct heat away from the panel.

Abstract: A system includes a vibration detector to detect a location of vibration and identify a frequency of the vibration. The system also includes a controller to generate audio corresponding to the frequency of vibration detected by the vibration detector and one or more speakers configured to provide the audio as directional sound.

Abstract: A sublimation generator including a sublimation tank configured to receive ice including at least carbon dioxide. The sublimation generator also includes a first heat exchanger in thermal communication with the sublimation tank. The first heat exchanger being configured to expel heat from a coolant into the sublimation tank to sublimate the carbon dioxide into a gaseous state. The sublimation generator also includes a gas turbine generator fluidly connected to the sublimation tank and configured to receive the carbon dioxide in the gaseous state.

Abstract: A system to perform multi-stage cleaning of material from a space suit worn by an astronaut in a deep space environment includes one or more discharge units installed external to an interior volume of a facility in the deep space environment. Each of the one or more discharge units releases one or more substances. The one or more substances includes water or air and the interior volume of the facility is defined by an interior hatch that is separated from an exterior hatch leading to the deep space environment by an airlock. One or more collection units installed external to the interior volume. Each collection unit traps released material that is released from a space suit based on the multi-stage cleaning to prevent the released material from entering the interior volume.

Abstract: An extraplanetary habitat system includes a habitat located on a site including a layer of regolith material and one or more heat-generating systems located in the habitat. A heat exchanger is operably connected to the habitat. The heat exchanger is located beneath the layer of regolith material and is configured to conduct the heat from the habitat into the layer of regolith material. A method of cooling one or more heat generating components of an extraplanetary habitat includes directing a flow of fluid from the habitat to a heat exchanger located beneath a layer of regolith material, exchanging thermal energy between the flow of fluid and the regolith material, thereby cooling the volume of fluid, and directing the flow of fluid from the heat exchanger to the habitat, thus cooling the habitat.

Abstract: A modular, multi-crew life support system and a method of assembling the system involve a fan to draw in ambient air. The system includes one or more assemblies that produce conditioned air from the ambient air, and a housing to support an oxygen source. The system also includes a port configured as an inlet from the oxygen source to augment the conditioned air, and a duct to disperse a result of augmenting the conditioned air as output air to support two or more occupants of an enclosure.

Abstract: A system includes a first communication system and a second communication system, each with a microphone, an array of speakers arranged to encircle a user of the communication system, a controller, and an array of antenna elements. In each communication system, the array of antenna elements transmits and receives over 360 degrees together, a positional correspondence between the array of speakers and the array of antenna elements is fixed, and the controller controls audio to be output only by speakers among the first array of speakers that correspond to antenna elements among the first array of antenna elements that receive communication.

Abstract: A helmet with an integrated microphone includes a first portion to attach to a mating ring. The first portion is shaped to create a volume for a head of a wearer. The helmet also includes a second portion to attach to the mating ring. The first portion is entirely surrounded by the second portion without being in contact with the second portion and the second portion is farther from the volume than the first portion. One or more vibration sensors are attached to the first portion. The one or more vibration sensors output an electrical signal and the microphone is formed by the one or more vibration sensors and the first portion.

Abstract: A generator includes a main cavity and a shaft located in the main cavity. The shaft is configured to be connected to an auxiliary power unit (APU) and rotated by the APU. The generator is configured to generate power based on the rotation of the shaft. A fluid system is configured to receive a fluid from the APU, flow the fluid through the main cavity and return the fluid to the APU through a fluid scavenge channel. A filter is configured to filter the fluid from the main cavity to the fluid scavenge channel and a sensor is configured to detect a characteristic of the fluid at the filter.
