Abstract: An exoskeleton system comprising an inflatable actuator configured to be worn by a user. The inflatable actuator includes a fluid-impermeable member that defines a fluid chamber at least in part by a membrane material and a first and second interface that each define sidewalls, the membrane material is coupled to the sidewalls of the first and second interfaces.

Abstract: A method of operating an exoskeleton system that includes obtaining a first set of sensor data from one or more sensors associated with one or more leg actuator units of an exoskeleton system during a user activity, the first set of sensor data indicating a first configuration state of the one or more actuator units; determining, based at least in part on the first set of obtained sensor data, to change configuration of the one or more leg actuator units to a second configuration state to support a user during the user activity; and introducing fluid to one or more fluidic actuators of the one or more leg actuator units to generate the second configuration state by causing the one or more fluidic actuators to apply force at the one or more actuator units.

Abstract: An exoskeleton system having an actuator unit configured to be coupled to a leg of a user. The actuator unit includes an upper arm and a lower arm that are rotatably coupled via a joint, the joint 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; a fluidic actuator that extends between the upper arm and lower arm; and one or more fluid lines coupled to the fluidic actuator to introduce fluid to the fluidic actuator that causes force to be applied to the upper arm and lower arm.

Abstract: A fluidic exoskeleton system. The system can include one or more fluidic actuator units that have: a joint; a first and second arm coupled to the joint; an inflatable bellows actuator extending between a first and second plate associated with the joint, the inflatable bellows actuator defining a bellows cavity, the inflatable bellows actuator configured to extend along a length of the bellows actuator when inflated by introducing fluid into the bellows cavity; and one or more constraint ribs extending from the joint and surrounding portions of the bellows actuator along the length of the bellows actuator.

Abstract: The disclosure includes an exoskeleton network. The exoskeleton network includes an exoskeleton system that has one or more sensors and a memory; a user device that is local to the exoskeleton system and that operably communicates with the exoskeleton system; and a classification server that operably communicates with at least one of the exoskeleton system and the user device. The exoskeleton network performs feature extraction on sensor data obtained from the one or more sensors to generate feature-extracted sensor data and performs label derivation on the feature-extracted sensor data to generate labeled sensor data.

Abstract: A fluidic actuator unit that includes a joint, a first arm coupled to the joint, a second arm coupled to the joint; and an inflatable bellows actuator extending between a first and second plate associated with the joint, the inflatable bellows actuator defining a bellows cavity, the inflatable bellows actuator configured to extend along a length of the bellows actuator when inflated by introducing fluid into the bellows cavity.

Abstract: Methods are provided for reducing noise, sticking, and/or friction using a dry lubricant. The methods provide for application of a friction- and/or noise-reducing composition. The methods reduce friction, and/or noise for multiple applications. The methods also provide for reducing adherence of undesirable materials to articles.

Abstract: The disclosure includes a method of operating an exoskeleton system. The method includes determining a first state estimate for a current classification program being implemented by the exoskeleton system; determining a second state estimate for a reference classification program; determining that a difference between the first and second state estimate is greater than a classification program replacement threshold; generating an updated classification program; and replacing the current classification program with the updated classification program based at least in part on the determining that the difference between the first and second state estimates is greater than the classification program replacement threshold.

Abstract: A pipeline identification and calibration apparatus coupled to a pipe communicates with an in-line inspection tool to help a user to determine an extent of damage suffered by the pipe is provided. The apparatus includes a communication sheet coupled to the pipe and having a pipe calibration area and a pipe identification area, the pipe calibration area having a plurality of etchings, voids or magnetic inserts having variable dimensions and spacing between adjacent members of either the etchings, voids or the magnetic inserts. The user compares data generated by the in-line inspection tool to the etchings, voids or magnetic inserts on the pipe calibration area of the communication sheet to determine the extent of damage to the pipe.

Abstract: A process for dyeing keratinous fibers such as hair which comprises reacting the hair with a dyestuff of the general formula ##EQU1## where X is a chromophoric group, such as a group formed by coupling a phenylene diazonium salt with a diazo coupling compound, and where R has the formula --R'COOH, --R'COOCH.sub.3, --CH.sub.2 CH.sub.2 OH or --CH.sub.3 in which R' is an alkylene group containing 1,2 or 3 carbon atoms. The process gives good coloring of hair without damaging the condition.The invention also relates to novel dyes for use in the process and to processes for their production, and to dyeing compositions containing the dyes.
