Abstract: A tool system for installing a parking pawl includes a tool that includes a base, a plate, and an actuator. The base includes a base surface configured to support a parking pawl in a predetermined position. The plate includes a protrusion that extends upward from a front portion of the plate. A rear portion of the plate is coupled to a front portion of the base. The plate is movable relative to the base between a retention position in which the protrusion is positioned to retain a pawl spring loaded on the parking pawl in a pretensioned state, and a release position in which the protrusion is configured to release the pawl spring. The actuator is operably coupled to the plate such that activation of the actuator moves the plate between the retention position and the release position.

Abstract: A system can include an axial field rotary energy device with an axis of rotation and a rotor coaxial with the axis and having a shaft, bearings, rotor disks that are coaxial and permanent magnets on each rotor disk. A printed circuit board (PCB) stator is located between the rotor disks to define an air gap on each side of the PCB stator. An enclosure has two enclosure sections with an inspection port. Bearing caps and bearings are mounted to the rotor. A variable frequency drive (VFD) assembly is coupled to the axial field rotary energy device. The VFD has a flexible conduit that extends between the VFD housing and the axial field rotary energy device. The flexible conduit can adapt to different sizes of axial field rotary energy devices.

Abstract: A system for harvesting solar energy on a spacecraft includes a stiff substrate layer and a working layer disposed on the substrate layer to provide at least one of a photovoltaic or a reflective function. In a first operational state, the substrate layer is arranged as a tape spring to store potential energy which causes the substrate layer to uncoil and provide, in a second operational state, a photovoltaic module and/or a solar concentrator.

Abstract: A system has an axial field rotary energy device with a housing, an axis and a rotor with a shaft, bearings, rotor disks and permanent magnets. A printed circuit board (PCB) stator is between the rotor disks to define an air gap on each side thereof. A variable frequency drive (VFD) assembly has a VFD housing and first pads coupled to inductors to facilitate heat removal from the inductors. A concave cradle is coupled to a ferromagnetic core and has a same contour as an outer surface of the ferromagnetic core. A second pad is coupled to a rectifier module. A third pad is coupled to switching devices and has pins to align the switching devices with the third pad. Standoffs are coupled to the VFD housing to support a first printed circuit board assembly (PCBA). A second PCBA is mounted to a shield plate above the first PCBA.

The merchandiser may include a product area with either a number of shelves or a number of columns with the packages therein and a package sanitation system. The package sanitation system may include one or more ultraviolet lights positioned within the product area so as to sanitize the packages therein.

Abstract: A radar cloaking apparatus configured for positioning on a radar target and corresponding methods are provided. The radar cloaking apparatus comprises a radio signal emitter and computational circuitry. The computational circuitry is configured to cause the radar cloaking apparatus to at least reference a model encoding scattering properties of the radar target; determine a predicted reflection signature of the radar target from a selected interrogation angle based at least in part on the model encoding the scattering properties of the radar target; and cause transmission, by the radio signal emitter, of a cloaking radio signal along the selected interrogation angle. The cloaking radio signal is actively generated based on the predicted reflection signature of the radar target shifted in phase such that the cloaking radio signal is configured to destructively interfere with a reflected signal formed by an interrogating radar signal scattering off of the radar target.

Abstract: A method for managing propellant in a spacecraft is disclosed. The method includes storing liquid propellant in a tank under an operating pressure controlled using a product of chemical decomposition of the propellant. The method may include transferring the liquid propellant out of the tank and chemically decomposing a portion of it using, for example electrolysis. Thus generated one or more gas components may be introduced to the tank to control the operating pressure in the tank.

Abstract: Fastener systems and methods of attaching one or more layers of materials to a roof deck of a roof structure for forming a roof are disclosed. In embodiments, the fastener systems can include a plate having first and second surfaces with an aperture extending between the first surface of the plate and the second surface of the plate and configured to receive a fastener therein. A cover portion is provided to substantially enclose the first end of the aperture so as to cover a head of the fastener received within the aperture and protect the fastener from impacts due to objects striking the roof structure.

Abstract: A low profile brooder is provided, comprising a venturi, a burner base, a burner cap, and a baffle. The burner base and the burner cap reside adjacent to each other, with the burner cap disposed above the burner base and with a distribution chamber between them. A central axis is defined. A venturi resides below the burner base and is in fluid communication with the distribution chamber at the central axis. The venturi defines a fuel flow path between its upstream and downstream ends. The fuel flow path resides at least partially at one or more of an acute angle, a perpendicular angle, and an obtuse angle to the central axis. A baffle resides in the distribution chamber between the central axis and the periphery.
