  • Publication number: 20210185592
    Abstract: This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.

  • Patent number: 11039364
    Abstract: Methods and apparatus allow a mobile device to proactively switch to a new network by using quality of connection information and the rate of change of the received signal strength indication (RSSI) to proactively switch from a first network, such as a WiFi network, to the new network, such as another WiFi network or a cellular network. For example, the mobile device determines a rate of change of the RSSI for the first network. Based on the rate of change of the RSSI, the mobile device predicts when the RSSI of the network is beyond a quality threshold. Based on the prediction, the mobile device switches from the first network to a second network. In another example, the method and device uses a quality of connection of the first network connection to determine when to switch from a first network connection to a second network connection.

  • Patent number: 11024058
    Abstract: Disclosed are methods for encoding information in a graphic image. The information may be encoded so as to have a visual appearance that adopts a particular style, so that the encoded information is visually pleasing in the environment in which it is displayed. An encoder and decoder are trained during an integrated training process, where the encoder is tuned to minimize a loss when its encoded images are decoded. Similarly, the decoder is also trained to minimize loss when decoding the encoded images. Both the encoder and decoder may utilize a convolutional neural network in some aspects to analyze data and/or images. Once data is encoded, a style from a sample image is transferred to the encoded data. When decoding, the decoder may largely ignore the style aspects of the encoded data and decode based on a content portion of the data.

  • Patent number: 10992259
    Abstract: An oscillator comprising an RC oscillator and a bandgap reference source, wherein the bandgap reference source provides a reference current for the RC oscillator, and a temperature coefficient of the reference current is adjustable. Since the oscillation frequency of the RC oscillator has less dependency on a power supply, a clock source having a relatively precise frequency thus can be obtained; and based on the RC oscillator, the bandgap reference source having a temperature compensation function is added, the reference current generated by the bandgap reference source with an adjustable temperature coefficient is used for temperature coefficient compensation to the inherent temperature coefficient of the oscillation frequency of the RC oscillator, thereby reducing the effect of the temperature on the oscillator, so that the output frequency of the oscillator does not change with the temperature as far as possible, which improves the oscillation frequency precision of the oscillator.
