  • Patent number: 8212620
    Abstract: An amplifier device including an amplifier having an input for receiving an audio input signal and an output for sending an output signal to a load. A boosted-rail circuit is connected to a power source and has a single boosted rail connected to the BTL amplifier. Also, a common-mode circuit is coupled to the boosted-rail circuit and the BTL amplifier. The common-mode circuit sends a common-mode signal to the BTL amplifier that will dynamically track the output voltage supplied from the boosted-rail circuit to the BTL amplifier. In operation, the boosted-rail circuit reacts to the BTL amplifier and switches from a non-boost mode to a boost mode to increase the output voltage supplied to the BTL when the BTL amplifier requires additional voltage.

  • Publication number: 20110316627
    Abstract: A switching amplifier including a voltage sensor circuit connected to a high voltage supply rail for measuring the power supply voltage. A current sensor circuit is connected to the high voltage supply rail for measuring the power supply current. An error amplifier is connected to the switching amplifier and receives one or more values based on the measurements taken by the voltage sensor and current sensor, and the error amplifier produces an error signal when a predetermined power limit is exceeded. A signal limiting circuit is connected to the error amplifier and the switching amplifier and limits the output power to rated power at any rated load impedance when the error amplifier produces the error signal. This switching amplifier is capable of automatically limiting output power at rated power into all rated load impedances, and dynamically reacts to the frequency-dependant impedance of a typical audio system.

  • Publication number: 20110237053
    Abstract: A process of forming an electronic device, by forming the source and drain contacts using photolithography, incorporating a self-assembled monolayer (SAM) over the electrical contacts to form an increased work function of the source and drain electrodes and further forming more favorable charge injection properties or within the channel region to improve film morphology and therefore improve charge transport. The SAM material is added to the photoresist stripper during a step of the photolithography process of forming electrical contacts.

  • Patent number: 7504475
    Abstract: A process is presented for the production of high molecular weight polybenzimidazole, in two steps. Step one: provide a first reaction vessel and charge it with at least one aromatic hydrocarbon tetraamine, and a heterocyclic ring making up the dicarboxylic component. Heat the reactants under agitation. Terminate the agitation while continuing to heat the reaction mixture to about 230° C. while allowing the reaction mass to foam. Cool the reaction mass to a friable foamed mass. Crush the friable foamed mass to obtain a ground prepolymer. Step two; provide a second reaction vessel, transferring the ground prepolymer to it. A pressure wash of the first reaction vessel and the means for agitation to obtain a second ground prepolymer. Transfer the second ground prepolymer to the second reaction vessel. Heat the ground prepolymer and second ground prepolymer under agitation to a higher temperature than the first step until the desired degree of polymerization is achieved.

  • Patent number: 7038007
    Abstract: A process for a single-stage melt polymerization for the production of a high molecular weight polybenzimidazole which comprises the steps of: providing a reaction vessel having a means for agitation and a means for vacuum; charging the reaction vessel with reactants selected from: (A) a tetraaminiobiphenyl (TAB), and (B) a diphenyl isophthalate (DPIP); reacting the reactants under constant agitation and under a vacuum with an inert gas sweep; maintaining a reactant temperature which does not exceed 290° C. under constant agitation allowing pressure in the vessel to increase, with an inert gas sweep until a phase change is achieved, when the temperature reaches 250° C. pressure is increased to a slight positive pressure; and increase the reactant temperature and pressure within said reaction vessel while maintaining constant agitation and inert gas sweep, while maintaining a slight positive pressure. Preferably the vessel used in the instant invention is a high intensity reaction vessel.
