摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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. CSAM utilizes the CSA position and a 4D sound speed field derived from an ocean 4D General Circulation Model (GCM) constrained using Ocean Acoustic Tomography (OAT) in the ocean area of operation and further includes (1) computing a modeled result with an acoustic propagation modeling code that is compared with the received acoustic data using a known procedure called “bulk shifting” and/or (2) a new proposed procedure that uses calculated group speeds from the 4D sound speed field, to provide a higher accuracy estimate of the receiver position.

摘要： 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 red-absorbing filter, a microlens array, an infrared-filter, 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.

摘要： A system of modular components can be used with existing sensor suites to fuse data and determine the operating environment (surface contacts/tracks) for an autonomous marine vehicle and feed an autonomy decision engine to improve the vessel arbitration process in deciding which way to turn, how fast to go, obstacle avoidance, and mission monitoring. The system includes the ability to obey the set of navigation rules published by the International Maritime Organization, generally referred to as COLREGS (collision regulations).

摘要： A process for selecting an optimal individual user solution including an optimal rate allocation and associated price for a predetermined bandwidth of cellular network resources includes application of an iterative process and selection from multiple proposed user solutions. The inputs to the iterative process include at least an initial user bid, an initial network rate allocation, a generated user utility function and the cost data. The user utility function includes multiple application user functions. Optimal solution selection includes comparing each multiple proposed user rate allocation with the initial network rate allocation for the user and selecting the closest multiple proposed user rate allocation to the initial network rate allocation. The process may be applied to aggregated cellular carrier scenarios.
