A signaling of the layer ID for packets of a multi-layered video signal is described. In particular, an efficient way of signaling this layer association is achieved, with maintaining the backward compatibility with codecs according to which a certain value of the base layer-ID field is restricted to be non-extendable such as base layer-ID value 0 in the base layer-ID field. Instead of circumventing this restriction specifically with respect to this non-extendable base layer-ID value, the layer-ID of portions of the multi-layer data stream is signaled in an extendable manner by sub-dividing the base layer-ID field into a first sub-field and a second sub-field: whenever the first sub-field of the base layer-ID field fulfills a predetermined criterion, an extension layer-ID field is provided, and if the first sub-field of the base layer-ID field does not fulfill the predetermined criterion, the extension layer-ID field is omitted. |

Turbulence-free camera system and related method of image enhancement
A turbulence-free CCD camera system with nonclassical imaging resolution, for applications in long-distance imaging, such as satellite and aircraft-to-ground based distant imaging, utilizing an intensity-fluctuation correlation measurement of thermal light. The proposed camera system has the following advantages over classic imaging technology: (1) it is turbulence-free; (2) its spatial resolution is mainly determined by the angular diameter of the light source. For example, using sun as the light source, this camera may achieve a spatial resolution of 200 micrometer for any object on Earth. 200-micrometer resolution is insignificant for short distance imaging, however, taking a picture of a target at 10-kilometer, a classic camera must have a lens of 90-meter diameter in order to achieve 200-micrometer resolution. Unlike a classic camera, the proposed turbulence-free CCD camera system has adequate spatial resolution zoom a long distance and still distinguish the objects within a small area, even with a small lens. |

Method for a dynamic perpetual encryption cryptosystem
A dynamic computer communication security encryption method or system using an initial seed key and multiple random number generators of a specific design, whereby a sequence of independent random entropy values is produced by one set of random number generators and encrypted along with the message stream using the initial seed key, or the output of a second set of random number generators initialized with the initial seed key, and following the subsequent transmission of the variable encrypted entropy/message block, the entropy values are used to symmetrically or identically augment or increase the current uncertainty or entropy of the cryptosystem at both the sender and the receiver, prior to the next encryption block operation. The encryption process effectively entailing the use of multiple encryption ciphers, and the entropy augmentation process entailing the encryption or application of various logical mathematical operations on the already dynamic but deterministic internal state values of the second set of random number generators, effectively altering their deterministic outputs in a random probabilistic manner.Random length message value sequences from one or more data sources is combined with one or more random length entropy value sequences from an independent source, following which the entropy “updates” may also be used to alter, or change any cryptosystem variable, value or component in a randomly determined manner. In addition, while ensuring synchronization, the random entropy sequences also serve to “pollute” the cipher-stream and thereby hinder most current forms of cryptanalysis, while simultaneously injecting additional entropy into the cryptographic system and allowing for its propagation to affect any connected system nodes, and thereby introducing unpredictable entropy into the system pseudorandom number generator outputs, and thereby ensuring the perpetual generation of unpredictable random numbers.Super-encryption mechanics are independent of the user data, simple, fast and efficient, and can incorporate compression, error correction and asymmetric encryption authentication routines. But most importantly, super-encryption ensures resistance to brute force attacks (not possible to verify if a message was even sent), an ability to exceed “perfect secrecy” requirements, and an improvement on previous super-encipherment design, since overhead can be dramatically reduced from 100% overhead.Communication links previously established by system nodes with central authorities may be used for secure node authentication and registration, while allowing the central authority to broker and synchronize communication channels and providing mutual authentication and other security functions between the system nodes. |

Reservoir capacitor based analog-to-digital converter
Techniques to use reservoir capacitors in ADC to supply most of the charge to bit-trial capacitors as bit-trials are performed. An accurate reference voltage source, e.g., a reference buffer circuit, only needs to supply the difference, e.g., an inaccuracy, in the charge supplied by the reservoir capacitors. Instead of having to resettle for each bit-trial, the accurate reference voltage source has only to deliver the initial charge to the reservoir capacitors during acquisition and once more when the ADC is ready to sample onto the residue amplifier. These techniques can ease the demands on the reference buffer circuit and requirement of external decoupling capacitors, for example. |

Wafer-scale integration of vacancy centers for spin qubits
Embodiments of the present disclosure propose two methods for integrating vacancy centers (VCs) on semiconductor substrates for forming VC-based spin qubit devices. The first method is based on using a self-assembly process for integrating VC islands on a semiconductor substrate. The second method is based on using a buffer layer of a III-N semiconductor material over a semiconductor substrate, and then integrating VC islands in an insulating carbon-based material such as diamond that is either grown as a layer on the III-N buffer layer or grown in the openings formed in the III-N buffer layer. Integration of VC islands on semiconductor substrates typically used in semiconductor manufacturing according to any of these methods may provide a substantial improvement with respect to conventional approaches to building VC-based spin qubit devices and may promote wafer-scale integration of VC-based spin qubits for use in quantum computing devices. |
