  • Patent number: 11774457
    Abstract: Protein biomarkers may be used to rapidly and accurately diagnose stroke. Biomarkers may be utilized in a rapid and inexpensive test that could be used at the bedside or ambulatory setting to definitively indicate the presence or absence of stroke and its severity. Such a test would quickly stratify patients in need of immediate stroke treatment from those who are not having a stroke. The test may aid emergency personnel in the decision for the most appropriate treatment plan and treatment location, thereby minimizing morbidity and mortality of stroke patients.

  • Patent number: 11342482
    Abstract: Gallium nitride based devices and, more particularly to the generation of holes in gallium nitride based devices lacking p-type doping, and their use in light emitting diodes and lasers, both edge emitting and vertical emitting. By tailoring the intrinsic design, a wide range of wavelengths can be emitted from near-infrared to mid ultraviolet, depending upon the design of the adjacent cross-gap recombination zone. The innovation also provides for novel circuits and unique applications, particularly for water sterilization.

  • Publication number: 20210142200
    Abstract: Embodiments of this invention comprise modeling a team's state and the influence of training treatments, or actions, on that state to create a training policy. Both state and effects of actions are modeled as probabilistic using Partially Observable Markov Decision Process (POMDP) techniques. Utilizing this model and the resulting training policy with teams creates an effective decision aid for instructors to improve learning relative to a traditional scenario selection strategy.

  • Patent number: 10575787
    Abstract: A hydration sensor is provided that includes a circulator having a plurality of ports, an amplitude-modulated coherent source connected to a first port of the circulator, a rectifier or other power sensor connected to a second port of the circulator followed by an RF baseband low-noise amplifier, a coupling structure connected to the third port of the circulator, and a demodulator connected to the output of the rectifier. The hydration sensor can include an RF low noise amplifier between the circulator and rectifier, and/or a second amplitude modulator between the circulator and the coupling structure. The coupling structure can be either a guided-wave near-field structure or an interfacial capacitive or inductive element. In the former case, the hydration is determined by measuring the reflectivity of the guided-wave radiation, and in the latter case it is determined by measuring the change of reflectivity (through change of impedance) of the interfacial element.

  • Patent number: 10164609
    Abstract: A digital signal synthesizer for generating a frequency and/or phase modified digital signal output comprises an input buffer, a transform module, a processing module, and an output buffer. The input buffer receives a digital input that is represented in a frequency domain representation. The transform module stores a fractional order control system that models a desired frequency and/or phase response defined by an assembly of at least one filter component. Each filter component is defined by a Laplace function that is modified to include a non-integer control order having a variable fractional scaling exponent. The processing module multiplies or divides the digital input with the fractional order control system stored in the transform module. Moreover, the output buffer stores a synthesized output of the input, which is modified in the frequency domain, the phase domain, or both according to the desired frequency and/or phase response by the processing module.

  • Patent number: 9939394
    Abstract: A method performed by one or more processing devices includes conducting a plurality of tests of a manufacturing process. Each test is conducted at a different combination of at least a first process variable and a second process variable, and each test comprises locally heating a region of a structure, where the local heating results in formation of a thermal field in the structure, and assessing a temperature derivative of the thermal field. Based on results of the plurality of tests, a process map of the temperature derivative of the thermal field is generated, with the temperature derivative based on a function of the first process variable and the second process variable.
