  • Publication number: 20220142566
    Abstract: Articles, systems, and methods for rapid administration and active pharmaceutical compositions to subjects exposed to radiation and/or toxins are provided by this disclosure. There are currently few interventional technologies to protect against long-term morbidity and mortality from exposure to radiation and chemical warfare. Furthermore, as commercially available technologies such as additive manufacturing and small-scale chemical reactors have become more prevalent, the risk of misuse of such technologies by terrorists and rogue nation states to manufacture nuclear, radiologic, and chemical weapons continues to increase. Articles, systems, and methods described herein combine sensing technologies with drug release components, in order to provide an approach for rapid diagnosis of and response to exposure to radiation and toxic agents.

  • Patent number: 11329211
    Abstract: An active three-terminal superconducting device having an intersection region at which a hot spot may be controllably formed is described. The intersection region may exhibit current crowding in response to imbalances in current densities applied to channels connected to intersection region. The current crowding may form a hot spot, in which the superconducting device may exhibit a measurable resistance. In some cases, a three-terminal superconducting device may be configured to sense an amount of superconducting current flowing in a channel or loop without having to perturb the superconducting state or amount of current flowing in the channel. A three-terminal superconducting device may be used to read out a number of fluxons stored in a superconducting memory element.

  • Patent number: 11324611
    Abstract: A prosthesis, including a prosthetic foot, a prosthetic talocrural joint, a prosthetic ankle pivotally coupled to the prosthetic foot and a four-area bending beam. The four-area bending beam includes a U-shaped or other spring. One end of the spring is mechanically coupled via two of the four areas to the prosthetic foot. The other end of the spring is mechanically coupled via the other two areas to the prosthetic ankle. The spring resiliently resists pivoting of the prosthetic ankle about the prosthetic talocrural joint. The four-area bending beam exhibits an at least approximately constant moment along its length to maximize strain energy density, storing about four times as much elastic energy as a comparable cantilevered beam, thereby providing high stiffness and high range of motion to the ankle. The spring is modular, being easily replaced with another spring exhibiting a different stiffness, ex., to tailor the prosthesis to a user.

  • Publication number: 20220137169
    Abstract: Chemical-shift nuclear magnetic resonance (NMR) spectroscopy involves measuring the effects of chemical bonds in a sample on the resonance frequencies of nuclear spins in the sample. Applying a magnetic field to the sample causes the sample nuclei to emit alternating current magnetic fields that can be detected with color centers, which can act as very sensitive magnetometers. Cryogenically cooling the sample increases the sample's polarization, which in turn enhances the NMR signal strength, making it possible to detect net nuclear spins for very small samples. Flash-heating the sample or subjecting it to a magic-angle-spinning magnetic field (instead of a static magnetic field) eliminates built-in magnetic field inhomogeneities, improving measurement sensitivity without degrading the sample polarization.

  • Publication number: 20220138608
    Abstract: An all-to-all coupled, high-fidelity, error-correctable quantum computer can scale to hundreds of qubits within a single cavity of moderate cooperativity with existing neutral atom technology. This quantum processor can enact teleported gates among any pair of qubits using a local Rydberg interaction between each qubit and a separate network of atoms that distribute entanglement via a cavity mode. Small atomic ensembles at network nodes allow for ultrafast, nondestructive readout with high fidelity by substantially shifting the resonance of even a poor-quality cavity. Fast readout enables near-deterministic entanglement distribution among network atoms despite cavity losses as well as syndrome measurements of qubit atoms for error correction.

  • Publication number: 20220136949
    Abstract: Systems and methods for flowing particles, such as biological entities, in a fluidic channel(s) are generally provided. In some cases, the systems described herein are designed such that a single particle may be isolated from a plurality of particles and flowed into a fluidic channel (e.g., a microfluidic channel) and/or collected e.g., on fluidically isolated surfaces. For example, the single particle may be present in a plurality of particles of relatively high density and the single particle is flowed into a fluidic channel, such that it is separated from the plurality of particles. The particles may be spaced within a fluidic channel so that individual particles may be measured/observed over time. In certain embodiments, the particle may be a biological entity. Such article and methods may be useful, for example, for isolating single cells into individual wells of multi-well cell culture dishes (e.g., for single-cell analysis).

  • Publication number: 20220136974
    Abstract: Disclosed herein are systems and methods of obtaining a derivative Raman spectrum using an excitation or Raman pump beam whose wavelength is modulated in any suitable manner such as, for example, stochastically. Shifting the wavelength of the input excitation by a small amount in approaches like SERDS can isolate the Raman scatter from other spectral artifacts and reduce the false detection rate. For example, an input excitation sequence can be correlated with the response of an individual pixel of a detector. From this, pixels that have captured Raman scattered photons can be separated from pixels capturing non-Raman photons. These techniques can be expanded to other fields and/or types of spectroscopies that utilize a dispersive element detector with time-dependent spectral features.

  • Patent number: 11320647
    Abstract: Alloys of GeSbSeTe (GSST) can be used to make actively tunable infrared transmission filters that are small, fast, and solid-state. These filters can be used for hyperspectral imaging, 3D LIDAR, portable bio/chem sensing systems, thermal emission control, and tunable filters. GSST is a low-loss phase-change material that can switch from a low-index (n=3), amorphous state to a high-index (n=4.5), hexagonal state with low loss (k<0.3) over a wavelength range of 2-10 microns or more. The GSST thickness can be selected to provide pure phase modulation, pure amplitude modulation, or coupled phase and amplitude modulation. GSST can be switched thermally in an oven, optically with visible light, or electrically via Joule heating at speeds from kilohertz to Gigahertz. It operates with reversible and polarization independent transmission switching over a wide incident angle (e.g., 0-60 degrees).

  • Patent number: 11318278
    Abstract: A neuromodulator may output stimuli that causes a user to fall asleep faster than the user would in the absence of the stimuli. Alternatively, the stimuli may modify a sleep state or behavior associated with a sleep state, or may cause or hinder a transition from a waking state to a sleep state or from a sleep state to another sleep state. The neuromodulator may take electroencephalography measurements. Based on these measurements, the neuromodulator may detect, in real time, instantaneous amplitude and instantaneous phase of an endogenous brain signal. The neuromodulator may output stimulation that is, or that causes sensations which are, phase-locked with the endogenous brain signal. In the course of calculating instantaneous phase and amplitude, the neuromodulator may perform an endpoint-corrected Hilbert transform. The stimuli may comprise auditory, visual, electrical, magnetic, vibrotactile or haptic stimuli.

  • Patent number: 11322426
    Abstract: The present invention generally relates to a microjet array for use as a thermal management system for a heat generating device, such as an RF device. The microjet array is formed in a jet plate, which is attached directly to the substrate containing the heat generating device. Additional enhancing features are used to further improve the heat transfer coefficient above that inherently achieved by the array. Some of these enhancements may also have other functions, such as adding mechanical structure, electrical connectivity or pathways for waveguides. This technology enables higher duty cycles, higher power levels, increased component lifetime, and/or improved SWaP for RF devices operating in airborne, naval (surface and undersea), ground, and space environments. This technology serves as a replacement for existing RF device thermal management solutions, such as high-SWaP finned heat sinks and cold plates.
