Abstract: A helmet may include a shell defining a cavity to receive a user's head. The shell may include a shell outer surface and a receiving area recessed into the shell outer surface. A liner may be within the cavity and coupled to the shell. A facemask may be coupled to the shell. A front bumper may be coupled to the shell and the liner. The front bumper may extend from within the cavity to an exterior of the shell. The front bumper may be positioned at least partially within the receiving area of the shell.

Abstract: A catering box with active climate control is configured to transport “delicate” foods, such as grilled cheese sandwiches, hot dogs, and hamburgers, without inducing substantial sogginess in the bread of those food items. The catering box includes a heat mass configured to retain heat generated by a hot plate and to then radiate that heat, during transport, after the hot plate has been disconnected from a power source. In addition, the catering box includes an exhaust fan that actively controls internal specific humidity levels in order to prevent moisture from settling within the bread of stored food items. A microcontroller within the catering box monitors temperature and absolute humidity levels, computes the current specific humidity level, and then selectively engages or disengages the exhaust fan in response. With his approach, the catering box may limit the degree to which humidity settles within the bread of delicate food items stored within.

Abstract: A method of operating a modular exoskeleton system, the method comprising: monitoring for one or more actuator units being operably coupled to or removed from the modular exoskeleton system, the modular exoskeleton system comprising at least a first actuator unit configured to be operably coupled and removed from the modular exoskeleton system; determining that the first actuator unit has been operably coupled to the modular exoskeleton system; determining the first actuator unit has been associated with a first body portion of the user; determining a first new operating configuration based at least in part on the determination that the first actuator unit has been operably coupled to the modular exoskeleton system and the determination that the first actuator unit has been associated with the first body portion of the user; and setting the first new operating configuration for the modular exoskeleton system.

Abstract: A shock absorber includes a bottom rim, a top wall comprising a raised central portion and a top rim, a side wall extending between the top and bottom rims, and a corrugation surrounding a periphery of the raised central portion that (i) connects the raised central portion to the top rim, (ii) descends to a depth below half a height of the side wall, and (iii) is separated by a distance from a surface. Impact forces imparted on the shock absorber are attenuated by a first amount in a first stage by resistive yielding of the side wall; by a second amount in a second stage by depression of the central portion and resistive yielding of the corrugation associated therewith; and by a third amount in a third stage by resistive yielding of the corrugation in response to a force applied to the top rim upon contact with the surface.

Abstract: A cover includes a receiver having a concave-shaped inner surface and a flap including a first side coupled to the receiver and a second side including a fastener. The flap may be movable relative to the receiver from an open position to a closed position. The fastener may be configured to be coupled to the receiver when the flap is in the closed position.

Abstract: A cap for a reusable bottle and a compound-containing container is provided. The container is a separate, replaceable structure with a base (well/bowl) section containing the compound and a hinged or otherwise removable cap. The container is secured in a cavity in the top of the cap using appropriate detents that flex based upon the materials inherent resilient (e.g. a polymer material) to selectively engage with and disengage from the cap cavity. The cap can include a (unitary or integral) hook or ring that extends from the edges of the cap and can provide a stop that the lid of the secured container hinges against when placed in an open position. The hinge includes a detent adjacent to its front edge (opposite the side containing the hinge). This detent retains the lid in a closed position, but can be overcome by pressure applied by the user to open the lid.

Abstract: A sleeve for a glass bottle includes a first opening, a rounded shoulder below the first opening, a second opening counterposed to the first opening, a rounded shoulder above the second opening, a cylindrical body between the rounded shoulder below the first opening and the rounded shoulder above the second opening when the resides on a bottle. The sleeve is comprised of an elastomeric material and contracts at a point equidistant from the first and second openings when removed from the bottle. The sleeve contraction creates a pinch at the point equidistant from the first and second openings. The pinch is omnidirectional around the circumference of the sleeve. The diameter of the sleeve at the pinch is less than at least one of the diameter of the sleeve at the rounded shoulder below the first opening and the diameter of the sleeve at the rounded shoulder above the second opening.

Abstract: A device for receipt in a user's mouth includes a tongue engagement element having a front region, a rear region, and side regions that define an opening for receiving a user's tongue, means for retaining the user's tongue in a forward position, and means for changing the size of the opening. The tongue engagement element is shaped such that when placed in a user's mouth, the rear region extends over the user's tongue and the front region extends under the user's tongue. A method of securing a tongue engagement element in a user's mouth includes moving an expanded tongue engagement element under a front region of a tongue and over a rear region of the tongue, and allowing the tongue engagement element to return toward a non-expanded state. The tongue engagement element acts to resist rearward motion of the tongue.
