Microwave heating device
The present invention has a configuration of controlling a motor so as to stop a radiation antenna when the radiation antenna faces in a direction in which a reflected wave detection amount is minimized and to stop the radiation antenna when the radiation antenna faces in a different direction different from the direction in which the reflected wave detection amount is minimized. According to this configuration, first, the radiation antenna stops when facing in the direction in which the reflected wave detection amount is minimized. This extends a heating time under the most efficient condition, improving a heating efficiency in comparison with when the radiation antenna constantly rotates. Second, the radiation antenna stops when facing in the different directions. This causes uneven heating when the radiation antenna faces in the direction in which the reflected wave detection amount is minimized as well as when the radiation antenna faces in the different directions. As a result, the uneven heating is cancelled out by the uneven heating each other caused at different locations. In this way, it is possible to achieve the even heating. |

Traffic-priority based silencing techniques for interference mitigation
Techniques are described herein to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic.

To mitigate interference between different traffic types, a user equipment (UE) may transmit a device-to-device silencing message to other UEs. Upon receiving the silencing message, the other UEs may release any scheduled communication resources that at least partially overlap with the semi-persistent resources. |

The steering logic may be built around the capability of the device or its information in various registers or other information that indicates which networks are preferred for the device. This logic may be part of a roaming agreement that is negotiated between a home MNO and foreign MNOs. In this manner, IoT devices may be steered to a specific network or first foreign network provider, voice-over-long-term-evolution (VoLTE) devices may be steered to a second foreign network partner, and non-VoLTE devices may be steered to a third foreign network partner. In this way, a network operator may preserve their network bandwidth for devices that require or may use particular network technologies while others do not. |

Power-efficient discovery process for nodes within a wireless mesh network
A wireless network includes a plurality of nodes configured to implement an improved discovery process to efficiently and reliably pair with one another with low power consumption. A given node divides time into slots and then performs discovery operations during designated discovery windows. The discovery windows occur periodically but at different times of day. During a given discovery window, nodes attempt discovery using a reduced set of channels that varies from one window to the next, thereby increasing the likelihood that nodes operate on the same channel. Nodes also implement a pairing protocol to coordinate pairing, potentially avoiding situations where all nodes attempt to pair simultaneously. The discovery process may be completed expeditiously, thereby conserving power and extending the operational lifetime of nodes which rely on battery power. |

Techniques for determining an upper bound on visual quality over a completed streaming session
In various embodiments, a hindsight application computes a hindsight metric value for evaluation of a video rate selection algorithm. The hindsight application determines a first encoding option associated with a source chunk of a media title based on a network throughput trace and a buffer trellis. The hindsight application determines that the first encoding option is associated with a buffered duration range. The buffered duration range is also associated with a second encoding option that is stored in the buffer trellis. After determining that the first encoding option is associated with a higher visual quality than the second encoding option, the hindsight application stores the first encoding option instead of the second encoding option in the buffer trellis to generate a modified buffer trellis. Finally, the hindsight application computes a hindsight metric value associated with a sequence of encoded chunks of the media title based on the modified buffer trellis. |

Systems and methods for scalable network modeling
Embodiments of the present invention can use a protocol-independent, vendor-independent, efficient and scalable abstraction model for representing the forwarding functionality of networks. Such a model can be used for systematic analysis and verification of networks.

This representation can describe many combinations of packets in a space-efficient way, enables more efficient tracing and transformation operations, and can even represent traffic from large internet routing tables efficiently. As a result of the scalability benefits of this more effective way to store and operate on packet collections, network modeling can scale to some of the largest, most complicated networks—those where the benefits are the greatest. |

Adaptive speculative decoding
Examples herein relate to decoding tokens using speculative decoding operations to decode tokens at an offset from a token decoded by a sequential decoding operation. At a checkpoint, a determination is made as to whether tokens to be decoded by the sequential and speculative decoding operations align. If there is alignment, the speculatively decoded tokens after a discard window are committed and made available for access. If there is not alignment, the speculatively decoded tokens are discarded. A miss in alignment and a fullness level of a buffer that stores speculatively decoded tokens are assessed to determine a next offset level for a start of speculative decoding. A size of a discard window can be set using a relationship based on the offset level to improve buffer utilization and to attempt to improve changes of alignments. |
