Abstract: A class-D amplifier (10) includes a logic circuit (40) for controlling the operation of a switching bridge (11). The logic circuit (40) transmits the differential mode of a differential pulse width modulation input signal and deletes a central portion of the common mode of input signal, while preserving pulses of a minimum pulse width following a rising edge and preceding a falling edge in common mode of the input signal. Deleting the central portion of the common mode signal improves the efficiency and reduces the electromagnetic interference radiation of the class-D amplifier (10). Preserving the pulses of the minimum pulse width ensures the proper operation of the switching elements (12, 14, 16, 18) in the switching bridge (11), thereby reducing the distortion in the signal amplification.

Abstract: An insulated glass unit (IGU) comprises impact resistant safety films on the inner surfaces of the glass panes, providing an impact resistant, energy-saving IGU for use in windows and doors. A layer of the safety film providing energy savings may be trimmed from the edges of a glass pane; witch may be sealed within the interior of the IGU, preventing corrosion while providing no loss in impact resistance. A scratch-resistant, chemical vapor deposited coating may be added to an interior glass surface (i.e. facing the building interior) in order to prevent heat loss from the building. An IGU may have an Energy Star rating for both summer and winter use.

Abstract: A solar control coating is applied to a first glass pane interior surface and a low-E coating is applied to a second glass pane exterior surface. A safety film is applied over the coating on the interior surface of the first glass pane. The second glass pane has a low-E coating facing the interior of a room. A safety film is applied to the reverse side of the glass. The two glass panes are separated by a spacer and structural silicone is backfilled from each outboard end of the spacer to the coated inside surfaces of the first and second glass panes to form a two-glass pane composite.

Abstract: A film laminating adhesive is formed by admixing a polyester resin and encapsulated metallic flakes. The metallic flakes are encapsulated with a silane in a hydrolyzed condition modified with a surfactant or dispersion agent. A mounting adhesive is applied to an outside surface of a first clear PET film. A silicone liner is adhered to the outside surface. A second PET film is bonded to another side of the first clear film with the film laminating adhesive containing encapsulated metallic flakes to form the spandrel glass film composite adapted for bonding to a glass surface after removal of the silicone liner.

Abstract: This invention relates to window films and more particularly to a low haze colored window film wherein coloration of the window film is effected with a pigment. The invention further is concerned with a process for the manufacture of the pigmented window film. The window film of this invention is pigmented with a pigment having small particle size wherein the particles are coated with a resin binder which encapsulates the pigment particles. The encapsulated pigment particles are blended into an adhesive which is compatible with the resin binder which is used to encapsulate the pigment particles. The resulting adhesive is used to secure one or more film layers of a composite window film structure together. The resulting films have haze levels which approximate the haze levels of dyed window films. The window films of this invention have outstanding light stability.
