Abstract: The present disclosure involves continuous measurement of the likelihood of a semiconductor-process chemical to form wafer defects composed primarily of particle-precursor material. Specifically, this disclosure details methods to estimate the effects of terminal size and contact angle for droplets remaining on a wafer following a spin-dry process. In some examples, the methods involve tuning a liquid-to-aerosol-based measurement device to correlate the measurement value with the tendency of a chemical to form such defects.

Abstract: A glass-based assembly includes a glass or glass-ceramic substrate comprising a surface. The surface has flaws, such as a population of small cracks extending into the surface, whereby the substrate is weakened relative to ideal strength thereof. The assembly further includes a coating coupled to the substrate and overlaying at least some of the flaws. Ultimate strength of the substrate with the coating coupled thereto is greater than that of the substrate alone, without the coating.

Abstract: Disclosed is a window for a sensing system comprising a substrate, a first layered film comprising alternating layers of higher and lower index materials, and a second layered film comprising alternating layers of higher and lower index materials. The window comprises a maximum hardness, measured at the first layered film and by the Berkovich Indenter Hardness Test, of at least 8 GPa. The first and second layered films are configured so that the window has favorable antireflective and transmission attributes in an infrared wavelength range of interest, while providing relatively low reflectance and transmittance in the visible spectrum to provide a dark appearance and low signal noise.

The coating comprises a multilayer interference stack.

Abstract: A window for a sensing system includes a first layered film and a second layered film. The first and second layered film each include alternating layers of lower and higher refractive index materials. The first layered film includes a scratch resistant layer such that the window exhibits a maximum nanoindentation hardness of greater than or equal to 10 GPa when indented on the first layered film. The materials and thicknesses of the layers of the first and second layered films are selected such that the window exhibits relatively high transmittance and low reflectance in two distinct wavelength ranges of interest.

Abstract: Systems and methods for charging an electric bus having a charging interface on its roof may include determining that an approaching bus is supposed to be charged at the charging station, lowering the charging head of the charging station to land on the roof of the bus, and moving the bus with the charge head on its roof to engage the charging head with the charging interface.

Abstract: A hybrid three-layer system is presented. The hybrid three-layer system includes a two-layer composite system and an additively manufactured third layer comprising a lattice structure. The composite layer system includes a metallic substrate, a structured surface, and a thermal protection system. The structured surface may be additively manufactured onto the metallic substrate and includes structured surface features formed to project above the metallic substrate. Each of the structured surface features are separated from adjacent structured surface features by grooves. The thermal protection coating may be thermally sprayed onto the structured surface and is bonded to each of the structured surface features. The lattice structure is in contact with a surface of the metallic substrate of the composite layer system.

Abstract: A battery assembly for a local use vehicle has outer walls, electrical contacts, and a communication connection, the battery providing a quantity of energy to power the local use vehicle, the electrical contacts of the battery configured and located for electrical contact with the first electrical contacts within the battery compartment when the battery is in a fully-inserted position within the battery compartment, the communication connection of the battery configured and located for wireless non-contact communication with the communication connection within the battery compartment when the battery is in a fully-inserted position within the battery compartment. The battery further includes a grasping point extending from one of the outer walls of the battery, the grasping point configured for being grasped by the end effector of the robotic device to thereby move the battery back and forth between the fully-inserted position and a removed position outside of the local use vehicle via the opening.

Abstract: A system and method for selectively charging removable batteries used for powering a fleet of local use vehicles may include placing and selectively charging batteries in a charging repository. Batteries are charged to an at least threshold charge level at which the batteries may be used to power a vehicle in a duty cycle. Charging can be managed based on at least one of fleet battery replacement needs and electrical cost optimization. The repository includes at least one rack in which batteries may be charged and a robotic device for moving batteries back and forth between the rack and the vehicles. Charging batteries within the repository and supplying them to vehicles that drive to the repository for battery exchange provides efficient spatial usage.
