Abstract: A transparent face mask for enhancing communications while controlling release of respiratory droplets. The mask includes a body formed from a thin flexible plastic material such as polypropylene. The mask body has a center diamond shaped segment that cantilevers the mask body from the bridge of a wearer's nose. The body includes right and left side segments, which each extend outward from one of the four sides of a diamond-shaped center segment to form a segment-to-segment joint between adjacent side segment pairs that flexibly conforms the side portions to the wearer's face. The face mask includes risers formed of an elongate strip of flexible material with a cloth covering for comfort and ease of fit, and the risers each provides a contact point between the mask and the wearer's face adjacent to and inward of the ear from which the mask body is cantilevered away from the wearer's face.

Abstract: An assist device includes: a first brace configured to be worn on at least a waist of a user; an arm configured to extend along a thigh of the user and to rotate with respect to the first brace; an actuator configured to generate torque that rotates the arm; and a second brace provided on the arm and configured to be worn on the thigh. The arm includes an arm body and a holding portion. The holding portion is provided on the arm body such that the holding portion is movable in a longitudinal direction of the arm body. The holding portion holds the second brace such that the second brace is rotatable.
