Abstract: Structures including a curved corrugated wall fabricated from a plurality of layers formed of one or more shaped strips and methods of forming the structures are described. A shaped strip used in the fabrication includes a variable profile across the width of the strip with a first edge of a strip defining a series of cell profiles of a first geometric shape and a second, opposite edge of the strip defining a series of cell profiles of a second, different geometric shape, with each cell transitioning from the first profile to the second profile across the width of the strip. The geometry of the cell profiles at either end of each cell can be designed with respect to one another to allow for radial orientation of the strip about an axis with little or no deformation or stress on the strip edges.

Abstract: Passive dehumidifiers for environmental control units (ECUs) are presented. In embodiments, the passive dehumidifier may include a plenum with an intake to receive an airflow with moisture (e.g., water droplets, water vapor, etc.) present. Upon entering the passive dehumidifier, the airflow may experience a reduction in inertia and a change from a first direction to a second direction. The directional change may be sharp enough (e.g., greater than 90 degrees) that the moisture in the airflow are not able to follow the airflow and are instead directed to impinge and be collected on a collector wall, which may include one or more hydrophilic surfaces facilitating the impinged water droplets to form a liquid film upon impact on the collector wall. The film may collapse due to gravity and may be drained out through and/or on a hydrophilic screen mesh (e.g., hydrophilic screen mesh surface) on the collector wall surface(s).

Abstract: In one aspect, a compact augmented permeation system (CAPS) assembly includes a housing defining an interior cavity. The housing further defines a gas inlet for receiving gas within the interior cavity and a gas outlet for expelling the gas from the interior cavity. Additionally, the CAPS assembly includes a gas-permeable membrane positioned within the housing and defining a system boundary across the interior cavity such that gas received within the interior cavity via the gas inlet permeates through the gas-permeable membrane before being expelled from the interior cavity via the gas outlet.

Abstract: Methods and devices to implement mid-wave and long-wave infrared point spectrometers are disclosed. The described methods and devices involve bi-faceted gratings, high-operating-temperature barrier infrared and thermal detectors. The disclosed concept can be used to design flight spectrometers that cover broad solar reflectance plus thermal emission spectral ranges with a compact and low-cost instrument suitable for small spacecraft reconnaissance of asteroids, the Moon, and planetary satellites as well as mass-constrained landed missions.

Abstract: An apparatus such as a network switch includes a power supply device configured to control power supplied through ports such as Ethernet ports to the network devices such as wireless access portions that are part of a local network. The apparatus further includes a second power supply device with one or more switched outlets for providing direct power other devices of the local network. A controller in the apparatus may be programmed to control the power supply devices to execute to a diagnostic procedure or a reset procedure that cycles power, off and then on, to devices of the local network.

Abstract: The disclosure is directed to a blackbody calibration target having a textured silicon substrate comprising a base comprising a plurality of needle like structures extending away from the base and having a total emissivity of greater than 99.5% from an electromagnetic radiation source having a wavelength greater than or equal to about 400 nanometers and less than or equal to about 1 mm. The disclosure is further directed to a blackbody calibration target system, and instrument which includes the blackbody calibration target, and a method of calibrating an instrument.

Abstract: A system and method for web browsing contemporaneously displays multiple web pages, advertisements, or other applications, preferably within a single window, for a user to view. In a preferred embodiment, a current web page, a past web page, a future web page, and/or an advertisement or other application are contemporaneously displayed in a single window. In this embodiment, the present invention tracks a past web page and renders it in a first panel, renders the current web page in a second panel, and identifies a hyperlink in the current web page to retrieve and render the future web page in a third panel. In other embodiments, a host provides a list of web pages that are to be displayed in the panels. In other embodiments, a user selects a list of web pages that are to be displayed in the panels. In other embodiments, hyperlinks are filtered and/or prioritized to determine which web pages are to be displayed in the panels.

Abstract: A protective device such as a seat or helmet contains impact attenuating fluid (e.g., CO2, Air or Water) containing cells, sensors and electrically actuated exhaust valves for cushioning impact and decelerating a user (e.g., the contacting body part of the user) after an impact. Accelerometers and a pressure sensor supply signals to a microcontroller, which opens an exhaust valve if accelerations (or pressure) exceed a threshold. Expelling fluid provides a cushioning and damping effect, decelerating the wearer's head. Acceleration data, fluid pressure data and GPS position data may be wirelessly communicated to a monitor computer system.

Abstract: A probe request from a wireless station can cause the access point to contact a roaming enablement service and alter the services accessible through the access point. The roaming enablement service can identify preferred services of the wireless station and mediate automated negotiations between the access point and a service provider to determine whether the access point may provide a service from the service provider. Upon successful negotiations, the brokerage service can enable the access point to provide access to the preferred services.
