A piezoelectric substrate attachment structure including a press section pressed by contact, a piezoelectric substrate provided adjacent to the press section, and a base section provided adjacent to the piezoelectric substrate on an opposite side from the press section. The following relationship Equation (a) is satisfied:

da/Ea<db/Eb(a) wherein da is a thickness of the press section in a direction of adjacency to the piezoelectric substrate, Ea is a storage modulus of the press section from dynamic viscoelastic analysis, db is a thickness of the base section in the adjacency direction, and Eb is a storage modulus of the base section from dynamic viscoelastic analysis.

A knee brace is provided that having a foot support assembly, a knee support assembly, and a calf engagement assembly. The foot support assembly is adjustable relative to the knee support assembly. The calf engagement assembly has a calf brace and is connectable to the foot support assembly and the knee support assembly with adjustment straps. The foot support assembly includes a foot adjustment plate that is connected to a shoe engagement component. The knee support assembly has a knee adjustment plate and has a multilayer pad, and a knee pad connector component connects the multilayer pad and the knee adjustment plate. The knee pad connector component can be connected such that the multilayer pad is in line with or offset relative to the knee pad connector, or the knee pad connector component can be replaced with right and left offset knee pad connector components.

A support frame for a knee pad has three major components that interlock with each other to form a rigid and strong frame capable of supporting the weight of a person who is working on knees. The three components are molded of a rigid plastic material. The upper component has a knee seat and a strap for wrapping around the leg of the wearer; the lower component has a cuff for wrapping around the wearer's ankle. Fastener devices for attaching the knee pad and the straps to the support frame are either incorporated into or provided on the support frame.

Disclosed is a garment comprising a hooded-coat and overalls designed for improved durability and comfort. The garment is waterproof throughout. The coat has an outer layer of Kevlar fabric in the abdominal region, the outer edges of the sleeves, and along the hem. The overalls have an outer layer of Kevlar fabric on the front of the legs and on the seat. The hood and coat sections each have light reflective stripes for greater visibility and safety. There are also built in knee pads, pockets, and openings for comfort, storage, and ventilation. The garment is particularly well suited for outdoor workers exposed to weather extremes and hard, abrasive contact with the environment.

A protective clothing equipment is provided that is comfortable, stabilizing, and compatible with varying types of surfaces. One embodiment of the protective clothing equipment includes a shell, padding disposed in front of the knee of the wearer, the padding including a non-uniform stiffness.

An apparatus for applying a support/compression sleeve in embodiments of the present disclosure may have one or more of the following features: (a) a first sleeve applicator body for placement between the sleeve and a user's body, (b) an upper strap extending from upper strap receptors located at an upper portion of the first sleeve applicator body, (c) a lower strap extending from lower strap receptors located at a lower portion of the first sleeve applicator body, (d) a second sleeve applicator body for placement between the sleeve and the user's body, (e) an upper strap extending from upper strap receptors located at an upper portion of the second sleeve applicator body, and (f) a lower strap extending from lower strap receptors located at a lower portion of the second sleeve applicator body.

A clothing article having a support member is provided. The clothing article includes an outer shell, a portion of the outer shell being dimensioned to fit loosely on a body of a wearer. A support structure has a support member supporting the body of the wearer when positioned thereon, and fits snugly on the body of the wearer, At least one tether portion extends between the support member and at least one connection region that is secured to the outer shell. At least a part of the at least one tether portion is dimensioned to enable the outer shell to move substantially freely relative to the support member when the clothing article is worn by the wearer.

An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

An improved kneepad system for removably attaching a pair of kneepads to pair of pants. The improved kneepad system includes one or more external kneepad assemblies to be disposed along an outer surface of the pants. A fastening assembly is designed for removably attaching the one or more external kneepad assemblies to the pants. Each of the kneepad assemblies includes a pocket which houses a corresponding kneepad insert. Finally, the kneepad assemblies include a protective layer which is attached to the pocket.

An apparatus for applying a support/compression sleeve in embodiments of the present disclosure may have one or more of the following features: (a) a first sleeve applicator body for placement between the sleeve and a user's body, (b) an upper strap extending from upper strap receptors located at an upper portion of the first sleeve applicator body, (c) a lower strap extending from lower strap receptors located at a lower portion of the first sleeve applicator body, (d) a second sleeve applicator body for placement between the sleeve and the user's body, (e) an upper strap extending from upper strap receptors located at an upper portion of the second sleeve applicator body, and (f) a lower strap extending from lower strap receptors located at a lower portion of the second sleeve applicator body.
