Abstract: A boat used in a chemical vapor deposition (CVD) furnace is configured to hold one or more complex three-dimensional (3D) structures when performing a coating. A platform wafer is placed horizontally in the boat to support the complex 3D structures and a mount is positioned to secure the complex 3D structures on the platform wafer during the CVD process. One or more “witness” wafers may also be placed in the boat for analyzing the thin-film coating. The platform wafer may be positioned between or bracketed by the vertical wafers. Parts with coatings manufactured using LPCVD are further disclosed.

Abstract: In some embodiments, an electronic device displays suggested routes based on the characteristics of respective vehicles. In some embodiments, an electronic device receives data for respective vehicles from a source external to the electronic device. In some embodiments, an electronic device anonymizes a vehicle identifier and determines customized suggested routes using the anonymized vehicle identifier. In some embodiments, Starting Charge Maps and/or Buffer Maps are generated and/or utilized for route generation or suggestion.

Abstract: Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument. The mode-locked laser can produce sub-50-ps optical pulses at a repetition rates between 200 MHz and 50 MHz, rates suitable for massively parallel data-acquisition. The optical pulses can be used to generate a reference clock signal for synchronizing data-acquisition and signal-processing electronics of the portable instrument.

Abstract: Systems and methods are described for detecting and identifying discrepancies of states of objects and/or areas of interest in a space. In some aspects, an autonomous device may collect ground truth data of a space including information identifying objects each associated with a location in the space, and a condition associated with at least some of the objects. A checklist including a set of desired states for at some of objects may be obtained and compared to the ground truth data to produce a set of comparisons, where individual comparisons identify discrepancies between the ground truth data of an object and the desired state of the object. The discrepancies may be compared to a criteria for correction, and upon at least one satisfying the criteria, a notification indicating the at least one discrepancy may generated and/or performance of a corrective action triggered.

Abstract: An interspatial blocker for a thrust reverser system of a turbofan engine, and a thrust reverser system and a turbofan engine incorporating the same. The interspatial blocker includes a first and second flap that rotate from a stored position to a blocking position, and a leading-edge structure rotatably coupling the first flap to the second flap. The leading-edge structure is set up to be installed in a fan nacelle of a turbofan engine in a substantially radial orientation such that the first flap rotates in a first direction about a first axis extending in a substantially radial direction from the stored position to the blocking position, and such that the second flap rotates in a second direction about a second axis extending in the substantially radial direction from the stored position to the blocking position, with the first direction being opposite to the second direction.

Abstract: A fuel storage system has a tank access chamber with improved monitoring, servicing and maintenance capabilities. In particular, the chamber includes a sump monitored by a liquid sensor whose proper function can be automatically checked remotely, e.g., via an electronic controller or remote manual operation. In cases where such a check indicates a need for physical inspection of the sump sensor, the present system provides for sensor removal and installation by service personnel from a location outside the tank access chamber. Thus, the present system facilitates regular inspection and routine or unplanned maintenance without the need for a person to physically enter the tank access chamber.

Abstract: Systems and methods are described for disinfecting a space, such as an interior room. In some aspects, at least one object in the space may be identified, such as by a mobile disinfecting device (device) including an ultraviolet lamp. Next, the object(s) may be categorizing as a certain type based on whether the object allows some light to pass through or around it. A route for the device may be determined, where the route includes a path and speed of the device corresponding to different segments of the path to yield a dosage score (ultraviolet exposure) that meets or exceeds a threshold value for different areas of the space. In some cases, determining the route further includes determining at least one of a speed, a modified path, or an ultraviolet radiation characteristic for at least one segment of the path based on the categorization of the object(s).

The frame includes an outer structural section and an inner structural section configured to at least partially nest with the outer structural section. The outer structural section and the inner structural section sandwich the airframe attachment component and the engine support to form double shear connections between the frame and the aircraft attachment component and between the frame and the engine support.
