摘要:
One subject of this invention is the development of a novel region of interest (ROI) method, or Frame Segmentation Method that can be provided within a video stream, in real-time, or more precisely within a few milliseconds of video frame duration of 30 msec, or even in the sub-millisecond range. This video frame segmentation is the basis of Pre-ATR-based Ultra-Real-Time (PATURT) video compression. Still other subjects of this invention are morphing compression, and watermarking, also based on the PATURT. The applications of the PATURT innovation include ROI-based real-time video recording that has special applications for aircraft pilot/cockpit video recording in “black-box” devices, recording aircraft accidents, or catastrophes. Such black-box devices usually need to pass high impact (3400 g), high temperature (1100° C., in 1 h), and other harsh environmental tests. In this invention, they also have the capability of reporting the last cockpit events up to 0.5 seconds before an accident, including all cockpit sensor readings, as well as pilots' behavior, the latter with fully scrambled and non-recoverable facial information. Further applications include video surveillance. The latter can be also applied to missile defense (recognizing real target or real missile, from false targets (decoys)), or to other Ultra-Real-Time (URT) civilian and military scenarios.

A method and system for label-free detection of pathogenic and antibiotic resistant bacteria is disclosed. The method includes fabricating a G-FET/peptide device having a synthesized peptide probe capable of recognizing and binding to a bacterial target; performing electric-field assisted binding of at least one bacterial cell of the bacterial target to the G-FET/peptide device; and electrically detecting the binding of the at least one bacterial cell to the G-FET/peptide device.
摘要:
The present invention relates to a wave-absorbing metamaterial, comprising a substrate which is provided with two opposite lateral surfaces, wherein a plurality of periodically arranged artificial metal microstructures are attached on at least one of the two opposite lateral surfaces; when an electromagnetic wave having an incident direction vertical to the two opposite lateral surfaces of the substrate is transmitted to the wave-absorbing metamaterial, a relative permittivity of the metamaterial is substantially equal to a relative magnetic conductivity of the metamaterial. A wave-absorbing principle different from that of a conventional wave-absorbing material is employed on the wave-absorbing metamaterial; an ideal wave-absorbing effect is achieved by periodically arranging various artificial metal microstructures on the substrate and adjusting the artificial metal microstructures; and the wave-absorbing metamaterial has the advantages of minor weight, small thickness and simply adjustable electromagnetic parameters.

Embodiments of the present disclosure relate to an impedance matching component and a hybrid wave-absorbing material. The impedance matching component is disposed between a first medium and a second medium, and comprises a plurality of functional sheet layers. Impedances of the functional sheet layers vary continuously in a stacking direction of the functional sheet layers, with the impedance of a first one of the functional sheet layers being identical to that of the first medium and the impedance of a last one of the functional sheet layers being identical to that of the second medium.
