Abstract

A compact, low-power, high image rejection sideband separation receiver is provided. The receiver observes an input radio frequency (RF) signal of multiple spectral lines (spectral observation), then downconverts the signals to intermediate frequency (IF), and then separates the signals to be observed simultaneously in multiple channels. An embodiment is used to observe a signal (G-band) with two spectral lines and utilizes a two stage Weaver architecture to downconvert the signal's frequency, including a combination of mixers in the second stage that achieves the separation of two different channels.

Systems and Methods for Transmitting Streaming Symbols using Instantaneous Encoding

  • Guo, Nian

Abstract

Systems and methods for performing real-time feedback communication in accordance with various embodiments of the invention are disclosed. In many embodiments, instantaneous encoding is utilized for transmitting symbols from a streaming source over a DMC with feedback. In certain embodiments, instantaneous encoding is performed during the arriving period of the symbols. At time t, the encoder and the decoder calculate the priors of possible symbol sequences using the source distribution and the posteriors at time t−1. In a number of embodiments, the encoder and decoder then partition the evolving message alphabet into groups, so that the group priors are close to the capacity-achieving distribution. In contrast to the SED rule for symmetric binary-input channels, partitioning processes in accordance with several embodiments of the invention utilize group priors instead of group posteriors for the partitioning. In many embodiments, once the groups are partitioned, the encoder determines the index of the group that contains the true symbol sequence it received so far and uses the group index to determine the appropriate channel input.

Abstract

A method, system, and apparatus for an unmanned aerial vehicle (UAV) to autonomously reconstruct overflown terrain and detect safe landing sites. A UAV autonomously acquires on-board pose estimates from an on-board visual-inertial-range odometry method during flight. The on-board pose estimates are utilized as a pose prior and to regain metric scale during three-dimensional (3D) reconstruction. The on-board pose estimates are corrected based on a bundle adjustment approach using previously acquired images. 3D reconstruction is performed based on multiple captured images taken from an on-board camera. Range data from the multiple captured images is fused into a multi-resolution height map. A safe landing site on the terrain is detected based on the multi-resolution height map.

Abstract

A system provides descriptor-based feature matching during terrain relative navigation (TRN). A scale and orientation (SO) module acquires a source image, image and slope pixel windows, and ring mask. The SO module combines corresponding pixels from the image pixel window and the slope pixel window to generate intermediate values, accumulates the intermediate values into ring accumulators, sums the accumulated values to generate a final ring value, and determines an orientation stability measure, and final scale and orientation values. An extract descriptors (ED) module acquires the source image, the image and slope pixel windows, final scale and orientation values, sector values, and a rink mask value. The ED module identifies pixels of interest, reorients the sector values. combines corresponding pixels from the image pixel window and the slope pixel window, accumulates and normalizes the intermediate values, and generates an image feature descriptor per coordinate.

Abstract

A synchronization system for synchronizing photons in a quantum teleportation network. The synchronization system includes a multiplexer combining a clock pulse with a signal photon (carrying a qubit) in an optical fiber, the optical fiber connecting a transmitter node (including the multiplexer) and a receiver node (comprising a demultiplexer). The signal photons have signal wavelengths red shifted as compared to clock wavelengths of the clock pulses. The clock pulses have an intensity below a threshold, such that Raman scattering of the clock pulses by the fiber (shifting the clock wavelengths into the signal wavelengths) is negligible.

Abstract

A two-dimensional lattice or mesh scaffold for therapeutic cell implants is disclosed as well as methods for manufacture and use. The lattice is constructed of crisscrossing capillaries of hydrophobic parylene, such as parylene AF4, that may be coated with a hydrophilic polymer, such as parylene C, for cell adhesion. At each intersection of the crisscross, the intersecting capillaries are internally connected so as to allow oxygen to flow freely within. The walls of the capillaries are thin enough to be permeable to oxygen, on the scale of a micron thick, so that oxygen can flow through the lattice and permeate through the capillary walls. For some implants, cells are sandwiched between two or more lattices, the cells being slightly held apart from aggregation with each other by the lattice holes. The implants may then be surgically implanted within a subject.

Abstract

Communication systems and methods in accordance with various embodiments of the invention utilize modulation on zeros. Carrier frequency offsets (CFO) can result in an unknown rotation of all zeros of a received signal's z-transform. Therefore, a binary MOCZ scheme (BMOCZ) can be utilized in which the modulated binary data is encoded using a cycling register code (e.g. CPC or ACPC), enabling receivers to determine cyclic shifts in the BMOCZ symbol resulting from a CFO. Receivers in accordance with several embodiments of the invention include decoders capable of decoding information bits from received discrete-time baseband signals by: estimating a timing offset for the received signal; determining a plurality of zeros of a z-transform of the received symbol; identifying zeros from the plurality of zeros that encode received bits by correcting fractional rotations resulting from the CFO; and decoding information bits based upon the received bits using a cycling register code.
