The UE sends downlink location measurements, such as Reference Signal Time Differences, for a plurality of base stations (BSs) to a serving BS at a layer 1 or layer 2 protocol level and at first periodic intervals. The UE and the plurality of BSs send additional location measurements, such as receive time-transmission time differences, to the serving BS at second periodic intervals, which are longer than the first periodic intervals. The serving BS uses the additional location measurements and downlink location measurements to determine timing information, such as Real Time Differences, for the plurality of BSs. The serving BS determines the location of the UE using the downlink location measurements and the timing information at the first periodic intervals and sends the location to the external client using user plane signaling to reduce delay. |

Radio circuitry controls wireless transmit power to User Equipment (UEs). The radio circuitry receives wireless signals generated using different Quadrature Amplitude Modulation (QAM) constellation sizes.

The encoder performs a detailed video analysis and selection of encoding parameters that using a machine learning algorithm improves over time. The encoding process is done using a multi-pass approach. During a first pass, the entire video file is scanned to extract video property information that does not require in-depth analyses. The extracted data is then entered into an encoding engine, which uses artificial intelligence to produce optimized encoder settings. The video file is into a set of time-based chunks and, in a second pass, the encoding parameters for each chunk are set and distributed to encoding nodes for parallel processing. These encoder instances probe-encode each chunk determine the level of complexity for the chunk and to derive chunk-specific encoding parameters. Following completion of the second pass, the results of both passes are then merged to obtain the necessary information for the encoder to achieve the best possible result. |

Introduced here are security management platforms configured to identify, assess, and monitor organizational vulnerability to security threats.

Technologies for long-lived 3D multimode microwave cavities
Technologies for a long-lived 3D multimode microwave cavity are disclosed. In the illustrative embodiment, a series of overlapping holes are drilled into a monolithic block of aluminum forming a cavity. The dimensions of the cavity formed by the overlapping holes can be made long by drilling a long series of holes in a row and can be made high by drilling holes a certain depth into the cavity. If two dimensions of the cavity are bigger than the diameter of the holes used to create the cavity, then the cavity can support electromagnetic waves that cannot propagate through the holes, leading to a long lifetime in the cavity. A superconducting qubit or other non-linear element can be inserted into the cavity, which can controllably interact with each of several modes of the cavity. In this way, the modes of the cavity can act as components in a quantum memory. |
