Active two-phase cooling systems incorporate a cooling medium that changes phase as it absorbs heat dissipated by a heat source and a pump or a compressor that urges the cooling medium through a cooling loop. Operation of some heat sources, e.g., electronic devices, can improve if maintained at a substantially uniform operating temperature. A cooling medium can enter a node for cooling such a heat source at or near a saturation state and can exhaust from the node as a saturated mixture, providing a substantially uniform temperature across the node while taking advantage of the cooling medium's relatively high latent-heat of phase-change to provide a high rate of cooling to the heat source. Although counterintuitive, a cooling loop can pre-heat a sub-cooled flow of the cooling medium to provide the medium to the node in a saturated state. Such pre-heating can be achieved by the saturated mixture of the cooling medium after exhausting from the node. |

Control and use of chroma quantization parameter values
Innovations in control and use of chroma quantization parameter (“QP”) values that depend on luma QP values. More generally, the innovations relate to control and use of QP values for a secondary color component that depend on QP values for a primary color component. For example, during encoding, an encoder determines a QP index from a primary component QP and secondary component QP offset. The encoder maps the QP index to a secondary component QP, which has an extended range. The encoder outputs at least part of a bitstream including the encoded content. A corresponding decoder receives at least part of a bitstream including encoded content. During decoding, the decoder determines a QP index from a primary component QP and secondary component QP offset, then maps the QP index to a secondary component QP, which has an extended range. |

Bandwidth estimation adaption for network stalls
This disclosure describes, in part, techniques for adapting bandwidth estimation algorithms to account for local network stalls (e.g., Wi-Fi stalls). For instance, an electronic device may use a pacer component and/or a network socket buffer to detect Wi-Fi stalls. The pacer component and/or the network socket buffer may both be configured to store packets. The pacer component may determine a number of bytes to send to the network socket buffer based on a current bandwidth (or bitrate) estimation value and may move packets from the pacer component to the network socket buffer. If the second queue reaches capacity at a first time and is no longer at capacity at a second subsequent time, a Wi-Fi stall may be detected, and the electronic device may transition from a first state to a second state causing the electronic device to determine whether to update a current bandwidth estimation value. |

Orthogonal time frequency space modulation techniques
Orthogonal Time Frequency Space (OTFS) is a novel modulation scheme with significant benefits for 5G systems. The fundamental theory behind OTFS is presented in this paper as well as its benefits.

We model the time varying delay-Doppler channel in the time-frequency domain and derive a new domain (the OTFS domain) where we show that the channel is transformed to a time invariant one and all symbols see the same SNR. We explore aspects of the modulation like delay and Doppler resolution, and address design and implementation issues like multiplexing multiple users and evaluating complexity. Finally we present some performance results where we demonstrate the superiority of OTFS. |

DC/DC converter using a differential geometric controller
Systems and methods relating to the conversion of DC power to AC power suitable for an AC power grid. DC power is received from one or more PV panels and is converted into DC power useful for charging an energy storage subsystem. The energy storage subsystem feeds into a DC/DC converter that converts the low voltage DC power into high voltage DC power suitable for a DC/AC inverter. The DC/AC inverter then converts the high voltage DC power into AC power suitable for an AC grid. A low voltage DC/DC converter can be used that is based on a differential geometry approach such that adjustable parameter values for components within the converter converge to nominal values as system parameters evolve. |
