    Patent number: 11226502
    Abstract: A high-brightness squeezed light source includes a plurality of light squeezing elements and a photonic summing device. The light squeezing elements each output respective squeezed light responsive to receipt of unsqueezed light. The photonic summing device receives the squeezed light output by each of the light squeezing elements and coherently adds the squeezed light to generate a high-brightness squeezed light output. The high-brightness squeezed light output has a greater brightness than the outputs of the light squeezing elements, and a same degree of squeezing as one or more of the outputs of the light squeezing elements.

    Patent number: 11222950
    Abstract: A layered heterostructure, comprising alternating layers of different semiconductors, wherein one of the atom species of one of the semiconductors has a faster diffusion rate along an oxidizing interface than an atom species of the other semiconductor at an oxidizing temperature, can be used to fabricate embedded nanostructures with arbitrary shape. The result of the oxidation will be an embedded nanostructure comprising the semiconductor having slower diffusing atom species surrounded by the semiconductor having the higher diffusing atom species. The method enables the fabrication of low- and multi-dimensional quantum-scale embedded nanostructures, such as quantum dots (QDs), toroids, and ellipsoids.

  • Probe for operando in situ electrochemical nuclear magnetic resonance spectroscopy
    Patent number: 11215686
    Abstract: Electrochemical devices with metal casings have been considered incompatible with nuclear magnetic resonance (NMR) spectroscopy because the oscillating magnetic fields (“rf fields”) responsible for excitation and detection of NMR active nuclei do not penetrate metals. According to the present invention, rf fields can still efficiently penetrate into nonmetallic layers of electrochemical cells (such as a coin cell battery configuration) provided the magnetic field is oriented tangentially to the electrochemical cell electrodes in a “skimming” orientation. As an example, noninvasive high field in situ 7Li and 19F NMR of an unmodified commercial off-the-shelf rechargeable coin cell was demonstrated using a traditional external NMR coil setup. The in operando NMR measurements revealed that irreversible physical changes accumulate at the anode during electrochemical cycling.

  • Systems and methods for electronic communication with a device using an unknown communications protocol
    Patent number: 11196611
    Abstract: Various technologies for communicating with systems that communicate using an unknown communications protocol are described herein. A transceiver intercepts a plurality of communications exchanged between two or more transceivers on a communications network. Pattern-recognition algorithms are executed over the plurality of communications, and features of an unknown communications protocol that governs the communications between the two or more transceivers are inferred based upon output of the pattern-recognition algorithms. A communication is formatted based upon the inferred features of the unknown communications protocol, and the communication transmitted to one or more systems on the communications network by way of the transceiver. The communication at least partially conforms to the unknown communications protocol, and so may be interpreted by systems on the network.

  • Multi-frame moving object detection system
    Patent number: 11188750
    Abstract: A plurality of remote sensing images of a scene are received. A potential target object can be identified in one of the images, wherein the target object has a low signal-to-noise ratio (SNR). A candidate motion path of the target object can be generated based upon the images. A predicted position of the target object along the candidate motion path is determined for each of the remote sensing images. An image chip is extracted from each of the images, where each image chip is centered about the predicted position of the target object in its corresponding image. A sum image chip is generated based upon the image chips. An indication that the potential target object is an actual object in the images is output based upon a value of a center pixel of the sum image chip.
