A soft physiotherapy instrument includes a flexible sheet and a controller. The flexible sheet includes a first flexible layer, a second flexible layer, a plurality of functional layers located between the first flexible layer and the second flexible layer, and a plurality of electrodes electrically connected with the plurality of functional layers. The functional layer includes a carbon nanotube layer including a plurality of carbon nanotubes uniformly distributed. The flexible sheet is electrically coupled with the controller via the plurality of electrodes.

Provided herein is are multilayer damping laminates comprising alternating damping and constraining layers. The materials and configurations of the damping layers are selected such that the damping layers have a decreasing glass transition temperature profile beginning at the first damping layer, allowing the laminates to effectively dissipate vibrations over a wider range of operating temperatures and/or frequencies. Also provided are systems and methods using the multilayer damping laminates.

Fireworthy sealants may have a variety of compositions and be made by a variety of techniques. In certain implementations, a fireworthy sealant may include a body comprised of a cured, tacky, soft, deformable non-adhesive gel. The gel body may have an upper surface, a lower surface, and a perimeter, wherein the upper and lower surfaces of the gel body, in an uncompressed state, define a body thickness. The sealant may, in an uncompressed state, be dimensioned to fit in a first opening between a wall and an aircraft component surface and deformable when under compression to fit in a second opening, smaller than the first opening. The sealant may be flame retardant and produce low smoke density and low smoke toxicity.

Present embodiments relate to assemblies for and methods of manufacturing laminate foam mattresses including, but not limited to, cushions and other mattress. More specifically, the embodiments pertain to, without limitation, a glue bridge assembly used to form laminate mattresses and the methods of using the glue bridge assembly.

An anti-fatigue mat is disclosed including a foam member and a gel member that each exhibit a different durometer. The foam member includes a support surface that supports the gel member atop the foam member. The foam member includes a foam ramp that extends outwardly downward from the gel member to a bottom surface of the foam member. A flexible cover layer is situated above the gel member and extends over the foam ramp so that the foam member and the flexible cover layer together encapsulatively seal the gel member therein. The flexible cover layer includes an indentation region situated substantially adjacent a gel/foam interface between the gel member and the foam member and further situated a predetermined distance from the peripheral edge of the mat in one embodiment. The bottom surface of the mat may include a non-slip surface to stabilize the mat on the particular surface that the mat covers.

A non-slip cushion includes a layer of a honeycomb gel for diminishing high pressure areas to reduce pressure ulcers.

The present invention relates to a double glazed window of a polycarbonate layer and, specifically, to a double glazed window of a polycarbonate layer, comprising an outer glass layer and an inner polycarbonate layer so as to have improved heat insulation and earthquake resistance. The double glazed window of a polycarbonate layer comprises: a glass layer forming an outer layer; a polycarbonate layer forming an inner layer; a vacuum layer (VL) formed between the glass layer and the polycarbonate layer; and sealing means for sealing the VL while coupling the glass layer and the polycarbonate layer.

A helmet comprises a protective shell, a first energy absorbing layer, a second energy absorbing layer and multiple displace devices. The protective shell forms an outer surface of the helmet. The first energy absorbing layer has a first outer surface and a first inner surface. The first inner surface is configured to couple the helmet to a wearer's head. The second energy absorbing layer has a second outer surface and a second inner surface. The second inner surface faces the first outer surface. The multiple displacement devices are positioned at multiple locations between the first energy absorbing layer and the second energy absorbing layer. The displacement devices allow displacement between the first and second energy absorbing layers in response to an oblique impact to the helmet.

An impact force dampening and defusing structure includes a plurality of components arranged in a grid array. A component has a three-dimensional geometric shape that includes an impact receiving surface area and an impact defusing surface area. The impact defusing surface area is larger than, and a distance d from, the impact receiving surface area. The component includes a material composition and, when an impact force strikes the impact receiving surface area of the component and the impact force dampening and defusing structure is in position to protect a body part, the component contributes to reducing pressure on the body part based on the material composition, the distance d, the impact receiving surface area, and the impact defusing surface area.

Provided herein is a vibration reducing sheet comprising a damping patch, a stiffening patch, and a substrate. The substrate is connected to the damping patch and the stiffening patch, and in some embodiments, the damping patch and the stiffening patch do not contact one another. The sheet can be connected to a base structure that is prone to vibrations. Because the damping patch and the stiffening patch can thus be applied to different locations of the base structure, the two patch types can independently be positioned to provide enhanced vibration reduction and mitigation.
