  • Patent number: 12021829
    Abstract: The invention relates to discovering and clustering Internet protocol addresses. For example, the invention can include discovering an IPv6 address of an Internet-facing device on a network, where the IPv6 address is associated with a wide area network (WAN) media access control (MAC) address and a WiFi basic service set identifier (BSSID), identifying an associated BSSID in WiFi geolocation databases based on the WAN and WiFi BSSID, and geolocating the Internet-facing device by retrieving a location record in the WiFi geolocation databases for the associated BSSID.

  • Patent number: 12020985
    Abstract: Methods for obtaining a free-standing thick (>5 ?m) epitaxial material layer or heterostructure stack and for transferring the thick epitaxial layer or stack to an arbitrary substrate. A thick epitaxial layer or heterostructure stack is formed on an engineered substrate, with a sacrificial layer disposed between the epitaxial layer and the engineered substrate. When the sacrificial layer is removed, the epitaxial layer becomes a thick freestanding layer that can be transferred to an arbitrary substrate, with the remaining engineered substrate being reusable for subsequent material layer growth. In an exemplary case, the material layer is a GaN layer and can be selectively bonded to an arbitrary substrate to selectively produce a Ga-polar or an N-polar GaN layer.

  • Patent number: 12012187
    Abstract: Provided is a maritime overboard locator system for use in locating and rescuing a person or asset that has fallen overboard into a body of water. The system includes a locator attached to a person or asset that is activated manually or automatically upon immersion in water. The apparatus emits light, sound, radio, or any combination thereof. The locator is detected by one or more detectors onboard a boat, ship, vessel, or structure. The detectors detect a unique signal that is assigned to each person/asset. Once detected, the detector sends an overboard alert and deploys an unmanned aerial or underwater drone. The drone can include an inflatable life preserver or life raft and a tether cord that helps the person to remain afloat until rescue can be accomplished.

  • Patent number: 12015824
    Abstract: An apparatus for passive coherent location includes a forecaster, an evaluator, a receiver, and a correlator. The forecaster generates a prediction of a radio-frequency signal transmitted from an antenna of a broadcasting service. The evaluator generates an effectiveness metric from the prediction of the radio-frequency signal. The receiver receives the radio-frequency signal that an object reflects from the antenna to the receiver. The correlator determines, from the radio-frequency signal reflected from the object as received at the receiver, an ambiguity function having a maximum at a temporal offset and a Doppler shift. The temporal offset and the Doppler shift at the maximum partially determine at least a position of the object. The apparatus optionally includes a selector for tuning the receiver to the radio-frequency signal in response to the effectiveness metric.

  • Patent number: 12006069
    Abstract: A method and apparatus uses a VLF transmitter, a VLF receiver, and/or a low earth orbit satellite including a rocket engine. A VLF wave transmitted into space is converted to an ambient wave. The ambient wave acts as a signal wave for a whistler traveling wave parametric amplifier. Rocket exhaust is generated in atmospheric plasma. The rocket exhaust includes kinetic energy acting as a Lower Hybrid wave source. The Lower Hybrid wave source produces a Lower Hybrid wave, which acts as a pump wave for the parametric amplifier. Nonlinear mixing of the signal wave and the pump wave in the atmospheric plasma simultaneously parametrically amplifies the ambient wave and generates an idler wave and a parametrically amplified wave. The parametrically amplified wave (1) reduces the density of energetic protons or killer electrons in the Van Allen radiation belt, and (2) improves communications between the VLF transmitter and VLF receiver.

  • Patent number: 12007271
    Abstract: Systems and methods are provided for interrogating a moving acoustic source using radar and processing data using a selection of motion compensation techniques adapted from synthetic aperture radar (SAR) to remove the effects of linear and nonlinear target motion so that the range-Doppler map retains only vibration information in the Doppler dimension. Vibration and sound waveforms can thus be selectively reproduced at specific ranges directly from the radar baseband waveform, without the need for additional complex analysis or audio processing.

  • Publication number: 20240183964
    Abstract: Provided is a test fixture for testing sonar transducer isolation rings. The fixture includes a stand, a pair of interchangeable isolation ring mounting bases, a mounting post, an actuator mounting bracket, a linear actuator, an actuator controller, a pair of weight alignment shafts, a weight, and an electrical test unit comprising a positive and a negative test lead. An Isolation Ring can be placed on the base for electrical and mechanical testing in order to detect dimensional tolerances and for voids or other area of insulating weakness caused during manufacturing. Additionally, the weight reduces strain and risk of injury to the operator while providing a repeatable pressure on the Isolation Rings during testing. The precise locating provided by the weight shafts and dowel pin eliminates operator error and accurately and consistently locates mating parts.

  • Patent number: 11993615
    Abstract: Tunable thermochromic materials comprise a metal salt with a varying proportion of two different anions and an organic ligand. Partial substitution via doping during the initial synthesis with a macro-structurally similar (generating an isostructural material) yet chemically different anion creates a material with altered thermochromic properties. For example, in bromide-doped bis(N,N?-diethylethylenediamine)nickel(II)) tetrafluoroborate; both the tetrafluoroborate (BF4-) and bromide (Br—) derivatives are isostructural. Substitution of BF4- for Br— causes a decrease in the materials' thermochromic transition temperature by approximately 10° C.
