  • Publication number: 20200375270
    Abstract: Active fabrics can be created by combining active and passive materials. Active materials with shape memory or other actuation characteristics can generate compression or dynamic fit, and the level of compression and/or change in fit can be determined by setting a knit index, wire diameter, and garment ease, or fit in relation to the body. Maximum compression can be set not only by varying physical properties of the knit structure but by built-in circuit breaking technologies, or by segmentation and control of the garment by a controller. In some embodiments, additive manufacturing can be combined with traditional textile equipment (e.g., circular knitting machine). Uniquely functional or active textiles can be made from additively manufactured, heterogeneous filaments. Yarn-like filament with varying properties (such as elasticity, stiffness, conductivity, activation, or surface properties) can be additively manufactured.

  • Patent number: 10815465
    Abstract: Provided are compositions comprising recombinant DNA polymerases that include amino acid substitutions, insertions, deletions, and/or exogenous features that confer modified properties upon the polymerase for enhanced single molecule sequencing. Such properties include increased resistance to photodamage, and can also include enhanced metal ion coordination, reduced exonuclease activity, reduced reaction rates at one or more steps of the polymerase kinetic cycle, decreased branching fraction, altered cofactor selectivity, increased yield, increased thermostability, increased accuracy, increased speed, increased readlength, and the like. Also provided are nucleic acids which encode the polymerases with the aforementioned phenotypes, as well as methods of using such polymerases to make a DNA or to sequence a DNA template.

  • Publication number: 20200100896
    Abstract: A delivery system and method for delivering a prosthetic heart valve to the aortic valve. The system includes a delivery catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve to the aortic valve through an introducer passing into the left ventricle through its apex. The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall while preserving good operating field stability. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.

  • Patent number: 10603957
    Abstract: A tire tread is provided that in an unworn state includes one or more tread features having a layer of a relatively softer, higher grip rubber material. This layer is formed from a first rubber composition that is provided as a skim or relatively thin layer at the contact surface of the tread feature. This skim provides the grip needed as the tire starts to warm up but can then wear away after an initial period of use so that the contact surface is eventually formed from a second rubber composition. This second rubber composition, in turn, provides the desired level of grip and acceptable wear at the higher temperatures that occur as the tire heats up from use. The layer of skim can be profiled depending upon the application and performance characteristics needed.

  • Publication number: 20200060822
    Abstract: A method of delivery a prosthetic heart valve includes inserting a delivery apparatus and a prosthetic heart valve into a patient's vasculature. The delivery apparatus includes a steerable guide catheter, a balloon catheter, and a flex indicator. The balloon catheter extends coaxially through the guide catheter, the prosthetic heart valve is mounted on a distal end portion of the balloon catheter, and the flex indicator is movably coupled to a handle of the guide catheter. The method further includes adjusting flexion of a steerable section of the guide catheter to position the prosthetic heart valve. The flex indicator moves relative to the handle of the guide catheter as the flexion of the steerable section is adjusted, and the handle comprises one or more visual indicators adjacent the flex indicator to provide visual indication of an amount of flexion of the steerable section of the guide catheter.

  • Patent number: 10385387
    Abstract: Methods for adding sequence tags during amplification of a nucleic acid target are provided. The target is amplified using two sets of primers that are modified such that only tagged targets can ligate to hairpin adapters that protect them from subsequent exonuclease treatment. Methods of making circular nucleic acids are also provided. Specific overhangs are created by exonuclease trimming with a polymerase such that only desired targets can ligate to sticky ended hairpin adapters that protect them from subsequent exonuclease treatment. Compositions, kits, and systems related to or useful in the methods are also described.

  • Patent number: 10348102
    Abstract: An energy module includes a capacitance-based power source structure, charging circuitry, a DC-to-DC conversion system, and an energy control module. The capacitance-based power source structure is operable to supply a voltage when the energy module is in a voltage supply mode, wherein, when substantially fully charged, the voltage is at least 48 volts and to receive a charge when the energy module is in a charge mode. The charging circuitry is operable to provide a regulated charge voltage to the capacitance-based power source structure when the energy module is in the charge mode. The DC-to-DC conversion system is operable to convert the voltage into one or more regulated supply voltages when the energy module is in the voltage supply mode. The energy control module is operable to determine the voltage supply mode and the charge mode.

  • Patent number: 10275593
    Abstract: A computing device includes central processing resources, memory, a network interface, and a security control module. The security control module determines when to change operation of a program of the computing device. When the operation of the program is to be changed, the security control module identifies a first processing resource of the central processing resources that is currently assigned to execute the program and selects a second processing resource of the central processing resources for subsequent execution the program. The security control module then ascertains first execution settings of the program as used by the first processing resource and facilitates conversion of the first execution settings into second execution settings for the second processing resource. The security control module then de-assigns the first processing resource from executing the program and assigns the second processing resource to execute the program.
