  • Patent number: 11190857
    Abstract: A system for collecting data from multiple sensors at a central node is described. The system includes multiple pairs of sensor array multiplexers (SAMs) and sensors connected in series along the length of two cables each having a twisted wire pair. A first end of the length of the two cables is connected to the central node for receiving data from each of the multiple pairs. The multiple pairs include sensors of at least two different types, which may have different sampling rates. The first cable carries timing data between the multiple pairs and the central node and the second cable carries sensor data between the multiple pairs and the central node.

  • Publication number: 20210341596
    Abstract: A process and systems for constructing arbitrarily large virtual arrays using two or more collection platforms (e.g. AUX and MOV systems) having differing velocity vectors. Referred to as Motion Extended Array Synthesis (MXAS), the resultant imaging system is comprised of the collection of baselines that are created between the two collection systems as a function of time. Because of the unequal velocity vectors, the process yields a continuum of baselines over some range, which constitutes an offset imaging system (OIS) in that the baselines engendered are similar to those for a real aperture of the same size as that swept out by the relative motion, but which are offset by some (potentially very large) distance.

  • Patent number: 11041754
    Abstract: A system and process scans a target area at a distance of 3-30 m for one or more materials. Scanning is performed by a coherent transmit beam aimed with the help of a thermal camera. The active source of the beam is a supercontinuum (SC) laser. The transmitted source beam is modulated by a high-speed Fourier-transform spectrometer prior to interaction with the target. Target reflected source beam is detected by an infrared detector, along with a reference portion of the transmitted source beam, as a series of interferograms; passed through a digitizer for digitizing the interferograms; and processed to producing spectrograms, wherein the spectrograms are indicative of one or more materials on the target.

  • Patent number: 11033622
    Abstract: This disclosure provides peptides which have a strong affinity for the checkpoint receptor “programmed death 1” (PD-1). These peptides block the interaction of PD-1 with its ligand PD-L1 as well as the interaction of CTLA4 with CD86 and can therefore be used for various therapeutic purposes, such as inhibiting the progression of a hyperproliferative disorder, including cancer; treating infectious diseases; enhancing a response to vaccination; treating sepsis; and promoting hair re-pigmentation or lightening of pigmented skin lesions.

  • Publication number: 20210109044
    Abstract: A scan head design uses 1:1 (one-to-one) imaging micro-lens arrays to transfer the object plane X-ray image from a CR-plate onto a linear photosensor. The scan-head includes a housing having therein, an array of red light emitting diodes (LEDs), a microlens array, and a sensor. The housing faces the CR-plate and the scan-head is translated across the CR-plate to read out the X-ray image therein. The scan head is compact and provides for improved spatial resolution and reduced power requirements.

  • Patent number: 10955523
    Abstract: An underwater navigation algorithm (UNA) uses acoustic signals transmitted in the ocean from sources at known positions to compute a position underwater for a vehicle that requires no initial a priori position or any ocean sound speed information or any initial GPS position that would require surfacing. The UNA consists of two parts, (1) the Cold Start Algorithm (CSA) and (2) the CSA with Modeling (CSAM). The underwater vehicle needs to be equipped with only a single hydrophone acoustic receiver and an onboard processor. The CSA requires only measuring the travel time of the end of the arrival coda (EOC) from each of the sources to compute a position. The CSAM is a post CSA procedure to calculate a higher accuracy position using the CSA position.

  • Publication number: 20210073637
    Abstract: Deep RCA uses a modified recursive least squares (RLS) optimization method and a novel null-class vector that together allow the algorithm to remember prior classes as it learns the new class. Deep RCA only has to be trained on the new class data which results in a significant improvement in training speed and almost no memory requirements to achieve the goal of near, real-time class augmentation for deep neural networks.

  • Publication number: 20210021339
    Abstract: Apparatus for detecting pulse optical position modulated signals with high background noise by detection of quantum arrival rate at the detector are described. Pulse signals at the detection limit are characterized by the arrival of clusters of individual photons at an optical receiver. The receiver has embedded shot noise that interferes with the detection of the signal of interest. The apparatus distinguishes the signal of interest by a measurement of the rate of arrival of the photons of the signal of interest from the ambient shot noise rate of the receiver. The apparatus determines the optimal signal detection criteria and calculates the expected bit error rate of the decoded data.

  • Patent number: 10801465
    Abstract: Wave energy conversion systems are provided utilizing a mass of water entrained in a collapsible water mass enclosure that is suspended beneath a float (e.g., a vehicle, buoy, platform, etc.) to provide an inertial force in opposition to the rising heave-induced acceleration of the float. The water mass enclosure is communication with a generator, such as by tethering one end of a tethering means to the generator and the other to the enclosure. The enclosure may be placed in communication with an intermediary hydraulic system, which is also in communication with the generator. In certain embodiments, the system will include a reel system for deploying and retrieving the water masse enclosure.

  • Publication number: 20200277643
    Abstract: A portable fluidic platform for rapid and flexible end-to-end production of recombinant protein biologics includes a bioreactor system hosting stable and robust cell-free translation systems that is fluidically integrated with modular protein separation functionalities (e.g., size exclusion, ion exchange or affinity chromatography systems) for purification of the cell-free expressed product and which are configurable for process-specific isolation of different proteins, as well as for formulation. The bioreactor utilizes lysates from engineered eukaryotic (e.g., yeast) or prokaryotic (e.g., bacterial) strains that contain factors for protein folding and posttranslational modifications. Combination of various purification modules on the same fluidic platform allows flexibility of re-routing for purification of different proteins depending on specific target requirements.
