Abstract: A head-mounted display (HMD) determines whether a set of criteria is satisfied based on eye-related readings collected by a camera of the HMD and wirelessly transmits a set of messages in response to a determination that the set of criteria is satisfied. An attachment includes a set of light-emitting diodes (LEDs) and activates the set of LEDs to emit the light at the bleaching intensity in response to receiving the set of messages.

Abstract: One variation of a system for power distribution of a trailer includes: a trailer chassis; a driven axle suspended from the trailer chassis; and a motor coupled to the driven axle. The system further includes a battery assembly coupled to the trailer chassis and configured to supply electrical energy to the motor to drive the driven axle and source electrical energy from the motor to slow motion of the driven axle. The system also includes a charging panel coupled to the trailer chassis and configured to couple to an external charging element. The system further includes a panel actuator configured to advance the charging panel from the trailer chassis to an open position to form a target gap between the external charging element and the charging panel and to retract the charging panel to a closed position to decouple the charging panel from the external charging element.

Abstract: A compact, mask-mountable powered air purifying respirator (“PAPR”) includes a housing and an impeller driven by a motor to draw air in through an inlet in the housing and direct the air to an outlet at an opposite end of the housing. The impeller comprises S-shaped fan blades that direct the air radially outward from the bottom of the impeller. The radial airflow meets S-shaped fins on a flow straightener that redirect the airflow downward through the PAPR housing outlet. The fan blades and flow straightener drive the airflow directly and efficiently, without unnecessary travel of air through the PAPR assembly, thus providing an improved airflow efficiency.

Abstract: An exoskeleton system, the exoskeleton system comprising one or more actuator units that include a fluidic actuator, one or more sensors and an exoskeleton device. The exoskeleton device includes a fluidic system, and a processor and memory, the memory storing instructions, that when executed by the processor, are configured to control the exoskeleton system to introduce fluid to the fluidic actuator of the one or more actuator units to cause actuation of the fluidic actuator of the one or more actuator units. The exoskeleton system may be configured to operate in, on or around a body of water and can be water and/or corrosion resistant.

Abstract: A method of configuring a treatment regimen of one or more exoskeleton systems in an exoskeleton network, the method comprising: receiving exoskeleton data from one or more exoskeleton systems that are operably connected to a network; storing the exoskeleton data from the one or more exoskeleton systems; generating a configuration input for configuring at least one of the one or more exoskeleton systems the configuration input including a replacement for or update to a current medical treatment regimen being implemented by the at least one of the one or more exoskeleton systems; and sending the generated configuration input to the at least one of the one or more exoskeleton systems via the network to cause replacing or updating the current medical treatment regimen being implemented by the at least one of the one or more exoskeleton systems.

Abstract: An exoskeleton system comprising a leg actuator unit that is configured to be coupled to a leg of a user. The leg actuator unit includes: an upper arm and a lower arm that are rotatably coupled via a rotatable joint, the rotatable joint configured to be positioned at a knee of the user with the upper arm coupled about an upper-leg portion of the user above the knee and with the lower arm coupled about a lower-leg portion of the user below the knee. The upper arm is configured to be coupled to the upper-leg portion above the knee via a first set of couplers that includes a first upper-leg coupler, the lower arm is configured to be coupled to the lower-leg portion below the knee via a second set of couplers that includes one or more lower-leg couplers associated with a lower-leg brace, and an actuator extends between the upper arm and lower arm, the actuator configurable to move the upper arm and lower arm.

Abstract: A container assembly includes a container body, a container capable of being received within the container body, and a collar. The container body includes an upper end having a first compression surface. The container includes a first flange configured to engage the first compression surface. The collar is capable of being releasably secured to the container body. The collar includes a second compression surface. A dispensing portion includes a second flange configured to engage the second compression surface. When securing the collar to the container body, the first compression surface engages the first flange and the second compression surface engages the second flange to cause the first flange to sealingly engage the second flange.

Abstract: A dual-purpose assault ladder and bridging apparatus includes a right frame and a left frame both including upper and lower frame tubes. Assault steps are connected between the right and left frames. Spanning supports connect upper frame tubes. Truss brackets secure one end of an assault step to the frame elements. Assault step support tubes are located to support the assault steps. Bridging steps are connected between the right and left frames and the assault steps. A top portion is mounted at an oblique angle slanting the top portion to position the angled assault steps substantially parallel to the ground when the ladder is leaned against a wall.
