Abstract: A method and system for electrical energy transfer and allocation that includes a blockchain systems for identifying and tracking energy demands and requests by geographical and coordinates and other characteristics through a usage and/or consumption chain that includes consumers and producers (prosumers). A microgrid identifier can be used to tag a consumer and relate the consumer to a producer by geography or demand. Based on demand and location data an energy factor can be calculated and thereby serve to match consumers and producers. A federated learning model can be used to accommodate an energy sharing stage on the blockchain and thereby facilitate, by a server computer, the transport of excess available energy from one energy producer in a first microgrid to either an energy consumer in the first microgrid or an energy storage unit of a second microgrid.

Abstract: Methods and techniques are described for increasing data rate at a high error performance in wireless transmission. A plurality of groups of p bits, wherein p is an integer greater than 1, is obtained. A transmission signal is generated, which includes, for a group of p bits dividing the group of p bits into a first subgroup of p1 bits and a second subgroup of p2 bits, wherein p1 and p2 are integers greater than zero. Based on the p1 bits, a sequence of modulation schemes is selected from a plurality of predetermined sequences of modulation schemes. The predetermined sequences are mutually different, and each of the predetermined sequences has length R, wherein R is an integer greater than 1. The p2 bits onto R subcarriers are mapped respectively by means of the R modulation schemes of the selected sequence. Finally, the generated transmission signal is transmitted.

The present invention also relates to a method used to initialize empty buffers in a storage of a system.

Abstract: Systems and methods for operating a quantum Otto cycle, including a superconducting LC resonator circuit electrically coupled to an input control unit with a reservoir source and a waveform generator configured to generate a bias current. A superconducting flux qubit is coupled to the LC resonator via a superconducting quantum interference device (“SQUID”). The SQUID generates a flux in the presence of the bias current, and the flux generated by the SQUID mediates a coupling rate between the flux qubit and the LC resonator. The waveform generator alternates the bias current to adiabatically change the coupling rate between the flux qubit and the LC resonator during adiabatic stages of the quantum Otto cycle. The reservoir source sends pulses to thermalize the flux qubit and the LC resonator system during isochoric stages of the quantum Otto cycle.

Abstract: A transparent screen includes a microlens array. The microlens array includes microlenses that are individually rotated to reflect a projected image to a common eyebox. The microlenses may have a dichroic coating to reflect narrowband light. An automotive windshield may include an embedded microlens array as part of a head up display. Eyewear includes an eyepiece with a rotated microlens array and a projector to project content on the microlens array.
