Abstract: A reusable container for transporting, inspecting, and/or storing a fuel cell or other item may include a crate or box lined with plurality of cushioning inserts to protect a fuel cell placed within the container, and a plurality of straps that extend inwardly from walls of the container and couplable to the fuel cell. The straps are tensionable to suspend at least a portion of the weight of the fuel cell from the walls of the container while a portion of the fuel cell may rest on top of cushioning inserts at the floor of the container.

Abstract: This disclosure includes plunger pumps having leak detection systems. Some pumps include a housing having a bore, an inlet, and an outlet, a plunger disposed within the bore and a first seal engaged with the plunger to divide the bore into first and second chambers, the plunger configured to reciprocate within the bore to expel liquid from the first chamber out of the outlet, and a sensor for detecting a presence of liquid in at least a portion of the second chamber. Some pumps have a reservoir for collecting liquid that leaks into the at least a portion of the second chamber, where the sensor is for detecting a liquid level in the reservoir. Some pumps include a second seal engaged with the plunger to divide the second chamber into first and second portions, and the sensor is for detecting a presence of liquid in the second portion.

Abstract: An Augmented Reality (AR) wayfinder tracks the current location of a user within an indoor location relative to a path defined through the indoor location for the user. The path is broken into segments, each segment is a straight line between two nodes, and each node represents either a starting point in the path, a turn along the path, or an ending point in the path. As the user traverses the path, a remaining distance between the user device and the next node in the path is calculated. An AR object with attributes that correlate to the remaining distance to the next node is blended into and superimposed into a video that the user is viewing through the user device of the physical environment as the user travels along the path.

Abstract: Support of coexistence of wireless transmission equipment in shared wireless medium environments is disclosed, which is applicable to various types of wireless transmission equipment. For instance, a wireless power transmission system (WPTS) delivers power to wireless power receiver clients via transmission of wireless power signals using one or more frequencies and/or channels within shared wireless medium environments in which other wireless equipment is operating, such as access points and stations in wireless local area networks (WLANs). The WPTS is configured to co-exist with the operations of the other wireless equipment within the shared wireless medium environment by adapting its transmission operations to utilize frequencies or channels that do not interfere with other equipment and/or implementing co-channel and shared channels operations under which access to channels is implemented using standardized WLAN protocols such as PHY and MAC protocols used for 802.11 (Wi-Fi™) networks.

Abstract: Methods and apparatus for detecting and handling evil twin access points (APs). The method and apparatus employ trusted beacons including security tokens that are broadcast by trusted APs. An Evil twin AP masquerades as a trusted AP by broadcasting beacons having the same SSID as the trusted AP, as well as other header field and information elements IE in the beacon frame body containing identical information. A sniffer on the trusted AP or in another AP that is part of a Trusted Wireless Environment (TWE) receives the beacons broadcasts by other APs in the TWE including potential evil twin APs. The content in the header and one or more IEs in received beacons are examined to determine whether a beacon is being broadcast by an evil twin.

Abstract: An indoor location is mapped into a grid comprising grid cells, each cell associated with items or objects detected as being present in the corresponding cell. The grid, grid cells, and linked items and/or objects are generated and updated using an Augmented Reality (AR) algorithm that maps a physical environment into cells and measures distances and directions within the environment relative to each cell. Walking paths (routes) to the items within the indoor location are generated using the grid information. As a user walks a path, the user's position within the indoor location is mapped and tracked to the cells and the path revised based on the user's actual position. A user device provides video via an AR application to track the user's position; a rendering of the position and path are superimposed within the video being viewed by the user on the user-operated device.
