Patent number: 11190857Abstract: 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.Type: GrantFiled: September 17, 2019Date of Patent: November 30, 2021Assignee: Leidos, Inc.Inventors: Mitchell Eric Boler, Steven Michael Johnson

Publication number: 20210341596Abstract: 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.Type: ApplicationFiled: September 30, 2020Publication date: November 4, 2021Applicant: Leidos, Inc.Inventor: John R.

Patent number: 11041754Abstract: 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.Type: GrantFiled: April 15, 2020Date of Patent: June 22, 2021Assignee: Leidos, Inc.Inventors: Augie Ifarraguerri, Brian Gorin, J.

Patent number: 11033622Abstract: 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.Type: GrantFiled: May 25, 2018Date of Patent: June 15, 2021Assignee: Leidos, Inc.Inventors: Gabriel M. Gutierrez, Vinayaka Kotraiah, Timothy W. Phares, James Pannucci

Patent number: 10955523Abstract: 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.Type: GrantFiled: November 6, 2017Date of Patent: March 23, 2021Assignee: Leidos, Inc.Inventor: Peter N. Mikhalevsky

Publication number: 20210073637Abstract: 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.Type: ApplicationFiled: October 29, 2020Publication date: March 11, 2021Applicant: Leidos, Inc.Inventor: Hanna Elizabeth Witzgall

Publication number: 20210021339Abstract: 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.Type: ApplicationFiled: October 6, 2020Publication date: January 21, 2021Applicant: Leidos, Inc.Inventors: James Charles Lundberg, Christopher Hochuli Fisher, Mark Edwin Krepel

Publication number: 20200277643Abstract: 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.Type: ApplicationFiled: April 10, 2020Publication date: September 3, 2020Applicant: Leidos, IncInventors: John Dresios, Richard Holmes Griffey, Challise J.
