Patent number: 10744695Abstract: Disclosed are compositions of a fused filament fabrication (FFF) composite filament having embedded functional materials in a thermoplastic matrix. Methods of making the composite filaments are also disclosed. In one example, a FFF composite filament incorporates a MOF, in an amount greater than 10% by mass, dispersed in a matrix polymer. One example of a method of synthesizing FFF composite filaments involves mixing a suspension that has a MOF with a matrix polymer solution to yield a polymer-MOF mixture. The mixture is cast and dried into a solid composite material, which is formed a FFF composite filament having the MOF in an amount greater than 10% by mass.Type: GrantFiled: January 18, 2018Date of Patent: August 18, 2020Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Rebecca L. Erikson, Josef F. Christ, Zachary C. Kennedy, Kent A. Evans, Christopher A. Barrett, Satish K. Nune

Paintable hydrophobic and lubricant-infused surface coatings and processes for making and using same
Patent number: 10221321Abstract: Compositions and processes are disclosed for forming hydrophobic coatings and lubricant-infused surface coatings. Coatings may be applied to various substrates without prior chemical or temperature treatment of the substrates and over large and irregular surfaces. Coatings are self-healing, anti-fouling, and have enhanced lifetimes.Type: GrantFiled: August 28, 2015Date of Patent: March 5, 2019Assignee: Battelle Memorial InstituteInventors: Raymond S. Addleman, Curtis J. Larimer, Christopher A. Barrett, George T. Bonheyo, Robert T. Jeters, Eric M. Winder -
Patent number: 10051650Abstract: Methods, systems, and devices are described for wireless communication. A method may include maintaining a plurality of conflict entries, each conflict entry indicating a first frequency range associated with interference by a first radio access technology (RAT) and a second frequency range associated with interference by a second RAT. Each conflict entry may indicate a first frequency range of component carriers of a RAT operating in carrier aggregation mode. Active coexistence conflicts may be identified between the first and second RATs based in part on the conflict entries and current radio conditions. The method may also include selecting one of the active coexistence conflicts for conflict mitigation. In some examples, a subset of the conflict entries are organized into an intermodulation group. The method may also include determining a conflict priority for each conflict entry associated with an active coexistence conflict. In some examples, conflict priorities may be aggregated.Type: GrantFiled: May 12, 2016Date of Patent: August 14, 2018Assignee: QUALCOMM IncorporatedInventors: Chetan Khosla, Brian Theodore Lubars, Christopher A. Barrett, Temitope Akinsipe

Publication number: 20170144373Abstract: Methods and systems for three-dimensional printing of conductive materials are disclosed. A molten filament containing a conductive material is extruded from a print head of a three-dimensional printer. A magnetic field is applied to the print head. The magnetic field may be a magnet or an electromagnet. The magnetic field may be applied at the tip of the extruder, nozzle, or nozzle tip of the print head.Type: ApplicationFiled: November 23, 2015Publication date: May 25, 2017Applicant: BATTELLE MEMORIAL INSTITUTEInventors: Rebecca L.

Patent number: 9235251Abstract: The aspects enable a computing device or microprocessor to determine a low power mode that provides the most system power savings by placing selected resources in a low power mode while continuing to function reliably, depending upon the resources not in use, acceptable system latencies, dynamic operating conditions (e.g., temperature), expected idle time, and the unique electrical characteristics of the particular device. Aspects provide a mechanism for determining an optimal low power configuration made up of a set of low power modes for the various resources within the computing device by determining which low power modes are valid at the time the processor enters an idle state, ranking the valid low power modes by expected power savings given the current device conditions, determining which valid low power mode provides the greatest power savings while meeting the latency requirements, and selecting a particular low power mode for each resource to enter.Type: GrantFiled: December 10, 2010Date of Patent: January 12, 2016Assignee: QUALCOMM IncorporatedInventors: Norman S. Gargash, Andrew J. Frantz, Brian J. Salsbery, Christopher A. Barrett

Publication number: 20130120010Abstract: A measurement instrument includes selectable channels for simultaneously measuring current on a power rail/load of a device under test. Multiplexor circuitry can be controlled to select power rails/loads for measurement and to couple unselected power rails to bypass the measurement circuitry. Active loads are provided in the measurement circuitry to compensate for loading by the measurement circuitry. The active loads cause current on a source side of a selected power rail/load to match current measured on a load side of the selected power rail/load during power measurements.Type: ApplicationFiled: May 21, 2012Publication date: May 16, 2013Applicant: QUALCOMM IncorporatedInventors: Clement B. Edgar, III, Brett L. Christensen, Christopher A. Barrett, Lakshmi P. Baskaran, Christopher F. Einsmann, Karthik N. Moncombu Ramakrishnan, Alfonso T. Trujillo, Alejandro Trujillo
