  • Publication number: 20190036504
    Abstract: A method of manufacture for an acoustic resonator or filter device. In an example, the present method can include forming metal electrodes with different geometric areas and profile shapes coupled to a piezoelectric layer overlying a substrate. These metal electrodes can also be formed within cavities of the piezoelectric layer or the substrate with varying geometric areas. Combined with specific dimensional ratios and ion implantations, such techniques can increase device performance metrics. In an example, the present method can include forming various types of perimeter structures surrounding the metal electrodes, which can be on top or bottom of the piezoelectric layer. These perimeter structures can use various combinations of modifications to shape, material, and continuity. These perimeter structures can also be combined with sandbar structures, piezoelectric layer cavities, the geometric variations previously discussed to improve device performance metrics.

  • Publication number: 20170264256
    Abstract: A method of manufacture for an acoustic resonator device. The method includes forming a nucleation layer characterized by nucleation growth parameters overlying a substrate and forming a strained piezoelectric layer overlying the nucleation layer. The strained piezoelectric layer is characterized by a strain condition and piezoelectric layer parameters. The process of forming the strained piezoelectric layer can include an epitaxial growth process configured by nucleation growth parameters and piezoelectric layer parameters to modulate the strain condition in the strained piezoelectric layer. By modulating the strain condition, the piezoelectric properties of the resulting piezoelectric layer can be adjusted and improved for specific applications.

The method may include providing an incremental latency adjustment to the circuit model by determining one or more end-points that are candidates for adjustment of a respective end-point's clock skew schedule. And, for each end-point that is associated with a negative front slack, adjusting a clock skew schedule of an end-point by a quantized amount. Further, for each end-point that is associated with a negative back-slack, adjusting the clock skew schedule of an end-point that is associated by a quantized amount. The method may also include repeating, the step of providing an incremental timing update. The method may include performing a timing evaluation upon the circuit model.

  • Patent number: 8091388
    Abstract: The present invention provides improved cooling of a veil of glass fibers by using a combination of nozzle assemblies. The nozzle assemblies include air caps of differing configurations to control the penetration of the spray into the veil. One suitable spray configuration is a nozzle assembly having punch air cap that creates a narrow exit angle, high velocity flow of droplets to penetrate the veil to cool the fibers at the interior. Another suitable configuration is a nozzle assembly having a flat air cap that creates a wide exit angle, low velocity, dispersed spray pattern to cool the exterior of the veil. Preferably, the flat air cap creates a very fine particle size to increase the cooling efficiency of the spray. By using the cooling ring of the present invention, lower levels of binder to be applied to the fibers and environmental emissions from the plant may be reduced.

  • Patent number: 7251959
    Abstract: A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system falls below about 8.5, thereby substantially reducing the corrosion rate of the components of the equipment associated with acidic polyacrylic acid binder, maleic acid cobinder or maleic anhydride cobinder and washwater solution. A closed-loop hoodwall washwater recovery system may also be introduced in addition to the neutralization system that allows for the recovery and reuse of polyacrylic acid binder and maleic acid cobinder or maleic anhydride cobinder with a minimal amount of base solution, thereby minimizing degradation of insulation properties of polyacylic acid bound glass fiber products.

  • Patent number: 7074200
    Abstract: This invention is an improved medical device for non-invasive pulsation, including counterpulsation or simultaneous pulsation, treatment of heart disease and circulatory disorder through external cardiac assistance. The device is a cuff which is affixed on a patient's lower body and extremities, and which constricts or expands by electromechanical activation, thereby augmenting blood pressure for treatment purposes. The cuff contains preferably fixed volume fluids such as gel, air, or water. The cuff envelops and is affixed to the patient's lower body and limbs. In an alternative embodiment, the cuff creates a fixed volume of air between the cuff and the patient such that the cuff creates a vacuum when expanding, thereby stimulating return of blood to the constricted region, permitting better and/or faster responses.

The device is comprised of cuffs which are affixed on a patient's lower body and extremities, and which constrict by electromechanical activation, thereby augmenting blood pressure for treatment purposes. Cuffs contain preferably fixed volume fluids such as gel, air, or water. Cuffs wrap around and are affixed to the patient's lower body and limbs. Computer or electronic means automatically correlate constriction of electromechanical actuators in the cuffs variably with the patient's measured physiological indicators, including diastolic and systolic heart functions, thereby augmenting blood pressure and optimizing benefit of counterpulsation treatment.
