Abstract: A speaker assembly is provided having a plurality of transducers disposed on a speaker body and configured to produce an audio beam being steerable based on at least one audio beam parameter. A light assembly is arranged on the speaker body and configured to produce a light output that varies based at least one audio beam parameter. The light output varies to provide a visual reference as the audio beam is steered.

Abstract: An insert (510) comprising a core (532) and one or more extensions (530) extending from the core. The insert is adapted to be inserted into a cavity of a hollow tube-shaped member (512). The hollow member can be a motorcycle handlebar or footrest. The insert can be made of metal or a polymer and can be an extrusion product.

Abstract: A panel structure and a method of forming the panel structure are disclosed. The panel structure typically includes at least one panel associated with a material. The panel structure has been found particularly advantageous for use as an interior panel of an airplane.

Abstract: A device charging system application to track one or more batteries configured to supply power to at least one load device and a central charging station in communication with the battery and including a transceiver and an electronic processor configured to define a virtual boundary within an area proximate to the central charging station, determine a proximate location of the battery, determine, based the location of the battery, whether the battery is within the virtual boundary, and transmit a command to the battery causing the battery to stop supplying power to the load device when the battery is not within the virtual boundary.

Abstract: A battery management system including a battery center and a controller. The battery center includes one or more battery receptacle. The battery center is configured to: receive one or more batteries, identify one or more batteries, and charge one or more batteries. The controller includes a memory and an electronic processor. The controller is configured to: receive, from the battery center, a status of one or more batteries, receive, from a user, an unlock request, and output, to the battery center, an unlock command. Wherein, the battery center unlocks one or more batteries from the one or more battery receptacle upon receiving the unlock command.

Abstract: The present teachings contemplate a method comprising providing a first and second substrate, locating an initiator onto a surface of the first or second substrate, the initiator including a substance for initiating polymerization of a polymerizable adhesive, locating the polymerizable adhesive onto a surface of the first and second substrate, the adhesive including a monofunctional, difunctional, or multifunctional methylene malonate, or cyanoacrylate, and contacting first and second substrate.

Abstract: A health and safety unit according to the present disclosure can include a vertically arranged panel having a first side and a second side opposite the first side and a mounting structure for movably mounting the panel to a housing. The panel can define a plurality of pockets extending through the first and second sides. Each of the plurality of pockets can be dimensioned to receive and support one or more items for storing within the housing. The panel, when movably mounted to the housing by the mounting structure, can be movable between a first position and a second position, wherein the panel and any items received therein are enclosed within the housing in the first position, and wherein the panel and any items received therein are accessible in the second position such that the one or more items can be removed from the plurality of pockets for use.

Abstract: A device charging system including a battery module and a central charging station. The battery module is configured to supply a type of power to at least one load device. The central charging station is in communication with the battery module. The central charging station includes an electronic processor configured to define a virtual boundary, determine a location of the battery module, determine, based the location of the battery module, whether the battery module is within the virtual boundary, and transmit a command to the battery module causing the battery module to stop supplying power to the load device when the battery module is not within the virtual boundary.

Abstract: A method for sealing a spring comprising providing a spring device, locating an activatable material within the spring device activating the activatable material, and installing the spring device into a desired location after activating the activatable material.

Abstract: A system and method is provided that facilitates controlling and monitoring environmental conditions in buildings. The system may include at least one rack including: a plurality of slidable field panels mounted in a housing. The slidable field panels may be in side-by-side relation in a horizontal direction and may be configured to independently slide at least partially out of a front side opening of the housing via a plurality of slides. The slidable field panels may include a plurality of components mounted to vertical walls thereof, including: transformers and building control modules. The rack may also include a terminal panel including a plurality of connection terminals facing a back side opening of the housing. The connection terminals may be respectively wired to respective terminals of the transformers and building control.

Abstract: One or more embodiments set forth include a personal aural device that includes an expandable eartip. The expandable eartip has a contracted state and an expanded state. The expandable eartip includes an insertion sensor configured to receive an indication that the eartip has been placed in an ear of a user. The expandable eartip further includes a controller configured to, in response, actuate a first device to inflate a first chamber to conform to a first portion of the ear. At least one advantage of the described techniques is that eartips in a set of earphones automatically inflate to provide an optimal fit for any listener's ears.

Abstract: The present teachings relate generally to a one-part epoxy-based adhesive paste composition, comprising: at least about 20% by weight of a liquid epoxy resin component; an amount of a halogen-free flame retardant sufficient so that the resulting cured adhesive composition exhibits sufficient flame retardancy for a vertical burn length of less than 6 inches according to FAR 25,853; at least two curing agents; and a lightweight low-density filler.
