  • Patent number: 10441550
    Abstract: The present invention is a bioactive, nanofibrous material construct which is manufactured using a unique electrospinning perfusion methodology. One embodiment provides a nanofibrous biocomposite material formed as a discrete textile fabric from a prepared liquid admixture of (i) a non-biodegradable durable synthetic polymer; (ii) a biologically active agent; and (iii) a liquid organic carrier. These biologically-active agents are chemical compounds which retain their recognized biological activity both before and after becoming non-permanently bound to the formed textile material; and will become subsequently released in-situ as discrete freely mobile agents front the fabric upon uptake of water from the ambient environment.

  • Patent number: 10402709
    Abstract: Devices, systems, and methods provide direct digitization and encoding of a parameter to be sensed or measured. Digitized readings are encoded into binary bits, which are acquired and handled by digital devices. An all-digital sensing device can be implemented in passive, active, or semi-passive forms, and in some embodiments includes a transducer, digitizer/encoder, reader, and transmitter. A transducer converts the parameter to be measured into a digitizable quantity, based on such as mechanical deformation, dielectric properties, or electromagnetic wave or acoustic-wave properties. A piezoelectric material transducer converts stress/pressure into resistance or voltage. A fiber-optic interferometer transducer converts pressure/temperature/PH into irradiation amplitude or wavelength shift in spectrum domain. Encoded binary or quasi-binary states are identified by a reader. Binary states have resolutions arranged according to a 2N format.

  • Patent number: 10269525
    Abstract: A liquid sampling, atmospheric pressure, glow discharge (LS-APGD) device as well as systems that incorporate the device and methods for using the device and systems are described. The LS-APGD includes a hollow capillary for delivering an electrolyte solution to a glow discharge space. The device also includes a counter electrode in the form of a second hollow capillary that can deliver the analyte into the glow discharge space. A voltage across the electrolyte solution and the counter electrode creates the microplasma within the glow discharge space that interacts with the analyte to move it to a higher energy state (vaporization, excitation, and/or ionization of the analyte).

  • Patent number: 10244818
    Abstract: Orthotics and methods for forming orthotics are described. The orthotics can be designed with a patient-specific design and can include variation in hardness across the orthotic so as to satisfy clinical need. An orthotic can be a custom-designed orthotic formed according to an additive manufacturing process such as a 3-D printing methodology. Through utilization of on-site formation methods such as 3-D printing, an orthotic can be designed, formed and fit at the point of care in a much shorter time period than traditional orthotics. The orthotics can include a layer that includes a plurality of cells across the layer. The layer can exhibit variable hardness across the layer through variation in cell void volume and optionally material of formation across the layer.
