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.

An avionics data storage device and data transfer system are provided. The data storage device, has a slanted, “shark-like” door, which provides an environmental seal when not installed in the data transfer system. The storage device and data transfer system maintain environmental seals at all times other than installation. The storage device and transfer system can implement a variety of identification and authentication methods, including electrical, physical, and optical authentication or identification.

A multifacet mirror comprises a catoptric structure configured to reflect light from a first field of view onto an image plane comprising a plurality of sensors, the catoptric structure having a surface comprising a plurality of facets separated by a plurality of catoptric regions; wherein a facet of the plurality of the facets has a second field of view that is smaller than the predetermined field of view; and wherein a catoptric region of the plurality of catoptric regions between two facets of the plurality of facets is configured to reflect light from a world point within the first field of view onto two of the sensors of the plurality of sensors.
摘要:
A system and method that will improve QoS (Quality of Service) of wireless video transmission systems. This is done by “in-fly” monitoring of BER by periodically transmitting “test images”, which images are known to the RF-receiver (Rx). BER can be automatically computed, within a related BIT (Built-in-Test) procedure that is also the subject of this invention. This allows predictions of a proper increasing, or decreasing of bandwidth OVH-level, in order to compensate for a BER-change. BER computation is facilitated by distinguishing video frames based on whether they depict new spatial events or related temporal events. Another subject of this invention is a motion-based pre-ATR method that is an introduction to common ATR, or pattern recognition methods. Yet another subject of this invention is a process of implanting error correcting bits into a payload, in the form of imperceptible watermarks. Still other aspects hereof, relate to such networks as: MAN, WAN, Tactical Internet, and others, to provide extra protection of headers, by implanting them into payloads, with a high level of Bit-Selective-Error Correction. Also included herein is a novel compression concept for still images which applies the spatial or meaningful frame technique to still imagery in a wavelet compression format.

A carton-centric security system that uniquely combines a low-cost version of the rugged connector technology and a novel smart skin is provided. The carton-centric security system includes RF electronics for communication. The system can fully meet the homeland security need to autonomously seal, secure, and monitor the integrity of shipping cartons/parcels below the ISO intermodal shipping container level. The system can seal the contents of a shipping carton within a “smart skin/wrapper,” which physically surrounds the contents, monitors the physical integrity of the shipping carton and detects any intrusion into the carton. In case of an intrusion, the system provides notification of the intrusion of the carton or tampering with the carton security system, including alteration of the carton contents, theft or unauthorized removal of the entire carton.
摘要:
An entirely wearable electrical connector for power/data connectivity. The principal element of a modular network is the wearable electrical connector, which is integrated into a personal area network with USB compatibility. Several wearable connector embodiments are disclosed. An enhancement to the wearable connector includes OSI Layer 2 (and potentially Layer 3) functionality. Data Link layer functionality is supported by including electronic serial numbers at wearable snap-connector points.

An improved stacked rotary connector assembly wherein each connector comprises a pair of rings and the rings of each rotary connector thereof are individually split and mechanically separable. Because the input and output rings are each split and separable, any one rotary connector may be removed from the stack without requiring removal of any other rotary connector and without disturbing the input/output buses of the assembly.
