  • Publication number: 20210344361
    Abstract: A method is shown that is operable to transform and align a plurality of fields from an input to an output data stream using a multilayer butterfly or inverse butterfly network. Many transformations are possible with such a network which may include separate control of each multiplexer. This invention supports a limited set of multiplexer control signals, which enables a similarly limited set of data transformations. This limited capability is offset by the reduced complexity of the multiplexor control circuits.

  • Publication number: 20210342730
    Abstract: A novel and useful system and method of quantum enhanced accelerated training of a classic neural network (NN). The quantum system implements an optimizer that accelerates training of the classic NN by exploiting the properties of quantum mechanics and manipulating the quantum system into a state that represents the complete state of the classic NN, including the loss function. The quantum system is then allowed to transition to its “optimum state” and the minimum energy state is read out from detectors and weight updates are calculated and fed back to the classic NN. Mapping and detection helper neural networks learn the characteristics of the quantum system structures. By averaging this over a number of images the learning weight or gradient of descent can be controlled to yield optimum neural network parameters. The time and energy required for training the classic NN as well as for inference is drastically reduced.

  • Publication number: 20210344725
    Abstract: A device may include a communication component that may communicatively couple to a first network. The device may also include a processor that may transmit a first signal via the communication component to a network address translation (NAT) system, the first signal including a first request to discover a server device. The NAT system may communicatively couple to the first network and a second network, such that the first network is inaccessible to the second network. The processor may then receive location data associated with the server device and transmit a second signal addressed to the server device based on the location data. The second signal is transmitted to the NAT system, such that the second signal may include a second request for a security policy from the server device. The processor may then receive the security policy via the NAT system and adjust one or more communication operations based on the security policy.

  • Publication number: 20210343293
    Abstract: Described herein is essentially a high-efficiency, hybrid fluid aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency than is possible in conventional blade-type wind turbines.
