Abstract

The disclosure deals with system and method for image gradient and derivative computation image processing. Noise, image sharpness, orientation, empirical parameters, and computational complexity are examples of image gradient and derivative computation challenges. Many traditional kernel-based operators excel at tackling one of these problems, but trade off their ability to handle others. Two new gradient detection kernels based on two-dimensional high order Taylor Series expansion tackle many such problems. The first kernel uses a wide range of the pixels in view to suppress noise, thereby improving the gradient intensities of edges. The second kernel builds on the first to leverage its noise suppression benefits while tackling an additional problem of degraded and low contrast edge boundaries. It can detect smooth lines in the presence of discontinuities and poor quality. The filter architecture allows for precise gradient calculation, edge detection, and orientation determination to less than one degree of the true value even when faced with signal to noise ratios that exceed 0.75.

Described herein is a method for packaging electrochemical reagents and enzymes into a low cost and compact ruggedized probe, suitable for use in harsh field conditions.

Abstract

Described herein is the preparation of a series of Cy5 phosphoramidites whereby the linker was shortened (n = 2) or lengthened (n = 4) to afford aggregates of dramatically different properties despite utilizing an identical DNA Holliday Junction or DNA duplex as the scaffold. Through the use of numerous spectroscopic methods (absorption, emission, circular dichroism, transient absorption, fluorescence lifetime) and molecular dynamics simulation, it was found that when n = 2, J- like aggregation is unexpectedly preferential and when n = 4, H- like aggregation is preferential. The shortened linker is of particular interest as the majority of previous aggregates formed by molecular scaffolding are H-like, or mixtures of H-like and J-like components, where these constructs can exhibit nearly pure J-like behavior. Conversely, the strength of the H-like behavior can be increased with incorporation of the longer, n = 4, linker.

Abstract

Quantum dots (QDs) and nanoplatelets (NPLs) are two types of nanoparticles used as scaffolds for enzymes operating in enzymatic cascades. Combinations of QDs and NPLs were surprisingly found to operate synergistically to create a greater enhancement than either alone when operating as scaffolds for enzymatic cascade reactions. A process involves providing an enzymatic cascade including a cluster of nanoparticles including both QDs and NPLs and having a plurality of enzymes bound thereto, the enzymes configured as an enzymatic cascade, such that the product of a first enzyme is a substrate of a second enzyme; contacting the cascade cluster with a substrate of the first enzyme; and allowing a reaction to proceed so that each of the plurality of enzymes acts in succession to produce an end product. The enzymes are bound to the nanoparticles via metal affinity coordination between histidine tags on the enzymes and zinc-containing surfaces of the nanoparticles.

Abstract

A method for using a single-pixel camera to reconstruct images of objects obscured by fog or other dynamic scattering media. A pseudo-random phase or intensity pattern is imposed on illumination beams directed at a target. The beam with the imposed pattern forms a pseudo random pattern on the target. Information regarding the pattern imposed on each pulse is entered into a data processor/controller. The illumination beams with the pseudo random patterns are reflected off the target, collected by receiving optics and a bucket detector and converted into electronic signals fed into the data processor/controller. The data processor/controller applies a high-pass filter to remove slower signal variations produced by dynamic changes in the scattering medium over time. The filtered bucket values are then used together with their corresponding speckle patterns to generate the images using any appropriate reconstruction algorithm such as CGI or CSI.

Abstract

Described herein is a one-pot, four-enzyme cascade of enzymes, three bound to quantum dots with one enzyme free in solution, for the conversion in vitro of fumarate to 1,3-diaminopropane. The cascade operates via two distinctly different enzymatic channeling mechanisms which simultaneously function to increase the overall rate. The first three enzymes of the pathway (AspB->LysC->Asd) were able to engage in channeling in a nanoparticle displayed format, but addition of the last two enzymes to this pathway in this format (AspB->LysC->Asd->Dat->Ddc) did not result in complete channeling through the entire pathway to the final diaminopropane product. Surprisingly, replacement of the last two enzymes (Dat->Ddc) with a naturally occurring fused Dat-Ddc hybrid (Daba) provided for full channeling in this system (AspB->LysC->Asd->Daba).

Abstract

A method of preventing photodegradation of dyes and pigments used in textiles and paints by surrounding photosensitive molecules with metal clusters that can absorb the damaging ultraviolet photons before they reach and damage the photosensitive molecules. A photosensitive dye or pigment is incorporated into a metal organic framework, which provides a scaffold to offer protection from ultraviolet degradation either by preferentially absorbing the ultraviolet light or by reflecting it before it reaches the dye. Isolating the dyes inside of the metal organic framework also sharpens the spectral features of the dye molecules.

Abstract

The invention provides a system for generating spatially explicit auditory cues for a recipient. It includes a processor to receive real-time location data of multiple physical entities relative to the recipient's spatial position and visual orientation. An audio generation module transforms this data into distinct audio signals using Head-Related Transfer Functions (HRTFs) to simulate perceived direction and distance. The output device, such as a headset or vehicle speakers, presents these audio signals spatially to allow perception of entities' relative locations. The system can adjust volume based on entity distance, integrate Doppler effects to indicate motion, and mute entities outside predefined distance boundaries. It also supports above-ground and ground assets, with altitude information converted to audible cues. The system monitors the recipient's orientation in real-time to adjust the HRTFs accordingly.

Abstract

Disclosed herein are systems and methods related to a capsule endoscopy, where a patient can swallow an ingestible capsule that records images of digestive tract, and a new in-body positioning system can precisely localize the capsule's position. Implementations include a new frequency-division multiplexing-based magnetic localization (FDMML) approach which leverages a higher frequency carrier in the low MHz range. The approach significantly reduces the reference excitation coil sizes and decreases the required excitation current by three orders of magnitude compared to prior work, making it practical for wearable systems. A fully integrated wireless receiver prototype is implemented in 180 nm bulk CMOS and packaged in an ingestible pill form factor. The new scheme achieves the best experimentally demonstrated tracking accuracy in both 2D and 3D localization experiments, achieving a sub-mm mean absolute position error and consuming only 247 pW while running at 100% duty cycle.
