Abstract: The present invention provides a foamed and/or aerated substrate for transmucosal and/or transdermal applications. The foamed and/or aerated substrate may be in the form of a film, sheet, strip or wafer. The foamed and/or aerated substrate is suitable for use in applications such as, for example, adhesive denture liners, tooth whitening, and smoking control/cessation. The foamed and/or aerated substrate is polymeric in nature and comprises one or more polymers and one or more foaming agents. Additionally, the foamed and/or aerated substrate may include, but not limited to, one or more plasticizers, hydrophobic barrier agents, tooth whitening agents, antioxidants, preservatives, super-disintegrants or absorbents, flavorants, deodorants, breath freshening agents, colorants, surfactants, film modifiers, cross-linking agents, antimicrobial agents, control release agents, other therapeutic agents, or any combinations thereof.

Abstract: A high-performance piston core including a first piston cylinder and a second piston cylinder, with a piston center longitudinally disposed between and magnetically coupling the first piston cylinder and the second piston cylinder. The piston center is made of high-performance magnetic material, such as Cobalt steel (CoFe), Silicon steel (SiFe), Vanadium/Cobalt steel (Permendur), alloys thereof, or the like. The high-performance magnetic materials exhibit high magnetic permeability and reduce the magnetic reluctance of flux bottlenecks. In addition, high-performance magnetic materials typically saturate at a higher flux density than the conventional magnetic materials. The first piston cylinder and the second piston cylinder can be made of conventional magnetic material, such as low-carbon steel. The first piston cylinder can include a ring disposed about an end, where the end is longitudinally attached and magnetically coupled to the piston center.
