Abrégé

The quantum relay and quantum signal source exploit quantum properties of photon streams. A pair of spatially separated and polarization-entangled photon streams is used. The pair collectively exist in a quantum superposition state by virtue of their mutual entanglement. In the relay, an encoder establishes a modulation control signal corresponding to the information to be conveyed. An optical quantum circuit is placed in the path of one of the pair of streams, so that the first stream passes through it. The optical quantum circuit alters the quantum polarization state of the photon passing through it based on the control signal. In this way information is encoded into quantum probability distributions of the superposition state through quantum parallelism and quantum interference, whereby information is conveyed in the photon streams. In the signal source a second information source is used to modulate the other of the pair of streams, thus enhancing the information density of the system, by encoding both in the probability distribution and in the correlation of the photon arrival times.

Abrégé

A reconfigurable sensor network uses continuous-variable (CV) multipartite entangled quantum states for distributed RF sensing with uncertainties below the standard quantum limit. A CV multipartite entangled state is generated with a quantum circuit that splits a squeezed vacuum state into spatially separated optical modes that are entangled. Each optical mode is transmitted to a RF-photonic sensor that imposes, on the corresponding optical mode, a quadrature displacement based on the local properties of an RF signal. A homodyne detector then measures the quadrature displacement. A post-processor combines the measurements to estimate a global property of the RF signal, such as an angle-of-arrival. To enable distributed sensing over large distances, the RF-photonic sensors may be spatially separated by several kilometers, or more. Alternatively, the RF-photonic sensors may be integrated into a single photonic system, such as a photonic integrated circuit.

In the wavelength selective fiber optic switch, an optical fiber with a portion of cladding removed defines a window facilitating access to the radially evanescent field present when optical power is propagating through the optical fiber, defining a first transmission path. The cladding removed optical fiber, a secondary optical waveguide, and a grating structure form a grating assisted coupler. An adjustable positioning fixture changes the relative spacing of the fiber core, grating, and output waveguide between a decoupled position and a coupled position. The switch operates, in the decoupled position, to allow optical power to propagate unperturbed through the first transmission path, including optical power at said optical wavelength, and in the coupled position, to extract and reroute optical power at the optical wavelength to propagate through the second transmission path, while leaving unperturbed other wavelengths propagating through the first transmission path. A tuning mechanism is implemented that alters the periodic properties of the grating to tune to a desired optical wavelength.

Embodiments of the present invention relate to systems and methods for improving the training of machine learning systems to recognize certain objects within a given image by supplementing an existing sparse set of real-world training images with a comparatively dense set of realistic training images. Embodiments may create such a dense set of realistic training images by training a machine learning translator with a convolutional autoencoder to translate a dense set of synthetic images of an object into more realistic training images. Embodiments may also create a dense set of realistic training images by training a generative adversarial network (“GAN”) to create realistic training images from a combination of the existing sparse set of real-world training images and either Gaussian noise, translated images, or synthetic images. The created dense set of realistic training images may then be used to more effectively train a machine learning object recognizer to recognize a target object in a newly presented digital image.

The present invention is directed to systems and methods for detecting objects in a radar image stream. Embodiments of the invention can receive a data stream from radar sensors and use a deep neural network to convert the received data stream into a set of semantic labels, where each semantic label corresponds to an object in the radar data stream that the deep neural network has identified. Processing units running the deep neural network may be collocated onboard an airborne vehicle along with the radar sensor(s). The processing units can be configured with powerful, high-speed graphics processing units or field-programmable gate arrays that are low in size, weight, and power requirements. Embodiments of the invention are also directed to providing innovative advances to object recognition training systems that utilize a detector and an object recognition cascade to analyze radar image streams in real time. The object recognition cascade can comprise at least one recognizer that receives a non-background stream of image patches from a detector and automatically assigns one or more semantic labels to each non-background image patch. In some embodiments, a separate recognizer for the background analysis of patches may also be incorporated.

A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV stores the cable on a spool and releases the cable into the water as the ROV dives away from the support vessel. The ROV detects the tension in the cable and the rate that the cable is released from the ROV is proportional to the detected tension in the cable. After the ROV has completed the dive and retrieved by the support vessel, the cable can be retrieved from the water and rewound onto the spool in the ROV.

Methods and apparatus for interleaving priorities of a plurality of virtual processors are disclosed. A hypervisor assigns a base priority to each virtual processor and schedules one or more virtual processors to execute on one or more physical processors based on the current priority associated with each virtual processor. When the hypervisor receives an indication from one of the virtual processors that its current priority may be temporarily reduced, the hypervisor lowers the current priority of that virtual processor. The hypervisor then schedules another virtual processor to execute on a physical processor instead of the virtual processor with the temporarily reduced priority. When the hypervisor receives an interrupt for the virtual processor with the lowered priority, the hypervisor raises the priority of that virtual processor and schedules the virtual processor with the restored priority to execute on a physical processor so that processor can handle the interrupt.

Abrégé

A cable (205) containing an optical fiber (301) is used to transmit da- ta between an underwater remotely operated vehicle (ROV) (201) and a support vessel (209) floating on the surface of the water. The ROV (201) stores the cable (205) on a spool (553) and releases the cable (205) into the water as the ROV (201) dives away from the support vessel (209). The ROV (201) detects the tension in the cable (205) and the rate that the cable (205) is released from the ROV (201) is proportional to the detected tension in the cable (205). After the ROV (201) has completed the dive and retrieved by the support vessel (209), the cable (205) can be retrieved from the water and rewound onto the spool (553) in the ROV (201).

A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV pulls the cable through the water and as the ROV dives away from the support vessel, the optical fiber is released from the support vessel. Excess tension in the cable can damage the optical fiber and the tension can be highest close to the ROV. To prevent potential damage to the optical fiber, the ROV can store a portion of the cable and release the cable if the detected tension approaches the maximum working load. When the tension drops to a lower safe level, the release mechanism can stop releasing the cable.

The present disclosure provides methods and apparatus for fast context switching in a virtualized system. In the disclosed system, a globally unique application-space identifier is associated with each guest application. No two applications share the same application-space identifier, even if the two applications reside in different virtual machines. Domain identifiers are used to ensure that a guest's mappings are only active when that guest is executing. A unique domain identifier is associated with each virtual machine, and all translation lookaside buffer entries thereby mapping the guest's kernel pages with that domain value. All other mappings are tagged with a predefined domain such as zero. In addition, a virtual memory management unit may be configured to support two virtual page table pointers and a configurable boundary between a virtual user page table and a virtual kernel page table. In such an instance, the two virtual page table pointers are presented to a guest operating system, and two physical page table pointers are associated with the two virtual page table pointers.

Embodiments include methods for determining synchronization/pilot sequences (SPS) to be utilized in conjunction with transmissions by antennas of a multiple-antenna transmitter. The SPS include pilot signals that are positioned at subcarriers that are orthogonal in frequency with subcarriers at which pilot signals of other antennas are positioned. The pilot signals may be unevenly spaced across the in-band subcarriers. The multiple-antenna transmit system generates a plurality of wireless signals, each of which may include an SPS having synchronization information in a first plurality of in-band subcarriers and the pilot signals in a second plurality of in-band subcarriers. The wireless signals are simultaneously radiated over a wireless communication channel using a different antenna. A receiver receives channel-affected versions of the wireless signals, and produces a corrected signal by applying corrections to the received signal based on estimated channel perturbations within the received signal.
