The present disclosure relates to a multi-layer thermal insulation blanket, designed to protect the upper body, having as characteristics retaining the heat emitted by the patient and reusing it to keep the patient warm, namely to control or prevent Inadvertent Perioperative Hypothermia during surgery proceedings in the operating room.

A polyimide film, a method of manufacturing the same, and a flexible metal foil clad laminate including the same. The polyimide film includes: a first imide bond unit having a glass transition temperature of 400° C. or higher; and a second imide bond unit having a glass transition temperature of less than 400° C., wherein the first imide bond unit is present in an amount of about 39 mol% to about 90 mol% in the polyimide film.

A vehicle or other system may have windows. The windows may be formed by laminating together molded sheets of polished float glass. Sheets of float glass may be polished on one side, leaving an opposing side unpolished. Following polishing, the sheets may be placed in a molding tool. The molding tool may mold the polished sheets into a desired shape such as a shape characterized by curved surfaces. The curved surfaces may include surfaces of compound curvature. Lamination equipment may use polymer to laminate first and second molded sheets of polished glass together with their polished sides facing outwardly away from each other. Light modulators and/or other electrically adjustable layers may be incorporated into the windows.

The present application discloses interlayers comprising novel polyesteramides comprising diols with tunable properties based on the monomers and monomer ratios used to prepare the polyesteramides and varying the reaction conditions. The interlayers have improved properties and can be used in many different applications.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth.
