  • Publication number: 20200220674
    Abstract: A wireless device performs spatial reuse in a wireless local area network. When receiving a packet, the wireless device measures a received signal quality from a first portion of the packet, and determines a required signal quality for correctly decoding a payload of the packet based on information in a packet header. The wireless device compares the received signal quality with the required signal quality. If the received signal quality is lower than the required signal quality, the wireless device transmits a signal that overlaps in time and in frequency with a second portion of the packet. Alternatively, a wireless device may identify a Basic Service Set Identification (BSSID) of a received packet. If the BSSID indicates that the packet is an inter-BSS packet, the wireless device transmits a signal overlapping in time and in frequency with the packet before reception of a frame check sequence (FCS) in the packet.

  • Patent number: 10233509
    Abstract: The present invention disclose a method for detection CPV 2a, 2b, and 2c in a sample by detecting VP2 gene. The signals can be detected by both fluorescent detection system and lateral flow immunochromatographic assay. The second object of this present invention is to provide a method to discriminate the wild type from the vaccine type. The first approach to achieve this object is discriminating wild type from vaccine type by SNP 36, which could be used on both fluorescent detection system and lateral flow immunochromatographic assay. The second approach to achieve this object is discriminating wild type from vaccine type by SNP 899 and SNP 963.

  • Publication number: 20170288852
    Abstract: A communication method is to be performed by a secondary transceiver. The secondary transceiver is operatively associated with a primary transceiver. The primary transceiver is configured to transmit an orthogonal frequency division multiplexing (OFDM) signal that has consecutive OFDM symbols. The OFDM symbol has a fixed OFDM symbol length and includes a cyclic prefix that has a fixed prefix length. The communication method includes steps of: A) upon receipt of the OFDM signal, determining a starting position of the cyclic prefix; and B) transmitting a to-be-transmitted signal during a time corresponding to the cyclic prefix of the one of the OFDM symbols or another one of the OFDM symbols subsequent to the one of the OFDM symbols.

  • Publication number: 20140328233
    Abstract: A portable device for receiving broadcast information is provided. A mixer down-converts a radio-frequency signal with a local oscillation clock to provide an intermediate frequency signal. A filter is arranged to filter the intermediate frequency signal. An analog-to-digital converter converts the filtered intermediate frequency signal into a digital signal according to a sampling rate. The broadcast information is obtained according to the digital signal. The local oscillation clock has a first frequency in a normal mode and a second frequency in a power-saving mode, and the second frequency is lower than the first frequency.
