Publication number: 20200047879Abstract: Embodiments are directed to systems and methods for creating a tubular composite structure. In one embodiment, a device comprises multiple layers of cured composite fabric bonded together to form a tubular composite structure, wherein alternating groups of the multiple layers comprise on-axis fabric and off-axis fabric. The tubular composite structure may form a spar for an aerodynamic component. The composite fabric may comprise one or more of carbon, fiberglass, or other composite materials, or a combination of materials. One or more stacks of the fabric wrap completely around the tubular composite structure, and other stacks of fabric may not wrap completely around the tubular composite structure.Type: ApplicationFiled: August 7, 2018Publication date: February 13, 2020Applicant: Bell Helicopter Textron Inc.Inventors: Christopher Edward Foskey, Jared Mark Paulson, Michael Christopher Burnett, Mark Mays

Publication number: 20200031086Abstract: Embodiments are directed to systems and methods for two or more cured composite assemblies that are bonded together to form a tubular composite structure, wherein each of the cured composite assemblies do not have a tubular shape. The tubular composite structure may form a spar for an aerodynamic component, for example. The two or more cured composite assemblies may comprise carbon or fiberglass composite materials or a combination of materials. Each of the cured composite assemblies may further comprise axial edges that are configured to be bonded to another of the cured composite assemblies, wherein the axial edges have a sloped shape. An adhesive agent may be applied on the axial edges for bonding two cured composite assemblies. Alternatively, or additionally, one or more fasteners may be used to attach the axial edges of at least two cured composite assemblies.Type: ApplicationFiled: July 30, 2018Publication date: January 30, 2020Applicant: Bell Helicopter Textron Inc.Inventors: Jared Mark Paulson, Mark Mays, Michael Christopher Burnett

Publication number: 20180335458Abstract: Sensing electronics may be used to measure capacitance of components, such as speakers in mobile devices. A sensing circuit may include a charge-sense front end with sine wave excitation, an analog-to-digital conversion block, and a digital demodulator. The component being measured by the sensing electronics may be excited by a high-frequency sine wave excitation. The digitization of the output from the component may be performed using a bandpass filter synchronized with the excitation signal by centering the bandpass filter near (e.g., within 5% of) the frequency of the excitation signal.Type: ApplicationFiled: May 18, 2017Publication date: November 22, 2018Applicant: Cirrus Logic International Semiconductor Ltd.Inventors: John L. Melanson, Anindya Bhattacharya, Axel Thomsen, Eric Smith, Vamsikrishna Parupalli, Mark May, Johann Gaboriau, Junsong Li

Publication number: 20180112510Abstract: A downhole intelligent reamer controller detects the difference between rotary drilling and sliding drilling, responds appropriately and quickly to multiple changes between rotary drilling and sliding drilling that may occur several times each stand of pipe. Additional controls prevent deployment of reamer members at inappropriate times such as when drilling out cement, testing, and running in and out of the wellbore. In one embodiment, a separate modular control sub is disclosed that may be utilized with and/or removably secured to an expandable reamer and/or other types of downhole tools.Type: ApplicationFiled: December 20, 2017Publication date: April 26, 2018Inventor: MARK MAY
