  • Publication number: 20260194441
    Abstract: A digital detection method for suspended particulate matter is disclosed and includes following steps: providing a particle sensor, wherein the particle sensor includes an airflow channel, a miniature pump, a laser emitter and a photodiode (PD). The miniature pump guides air having suspended particles toward a measuring region, and the laser emitter positioned orthogonal to the measurement region emits a laser beam, so as to generate scattered light. The scattered light is captured by the photodiode (PD) and transformed into an electrical signal. The photodiode uses a built-in digital algorithm to divide the electrical signal into N energy intervals. Numbers of the suspended particles are recorded cumulatively for each energy interval. A fine data distribution is formed for data processing and accumulation to calculate size of particles, total number of particles and concentration of the suspended particles for each particle size range (PM1, below PM2.5, and below PM10).

  • Patent number: 12659059
    Abstract: A method to perform beam management (BM) and/or synchronization (Sync) with interference cancellation on synchronization signal block (SSB) is proposed. A UE determines interference level and/or pilot contamination level. The UE can then perform BM or Sync, with or without interference cancellation, adapt to the determined interference and pilot contamination level. If interference level is high, UE applies interference cancellation for BM and Sync. If interference level is low, UE does not apply interference cancellation for BM and Sync. If the pilot contamination level is high, then UE follows the 3-symbol mode, e.g., uses only PECH0 SSS, and PBCH2 symbols for BM or Sync. If the pilot contamination level is low, then UE follows the 4-symbol mode, e.g., uses PSS as an extra symbol for BM or Sync to improve system performance.

  • Patent number: 12647233
    Abstract: A method to perform beam management (BM) and/or synchronization (Sync) using primary synchronization signal (PSS) when pilot contamination is low to improve system performance is proposed. A UE first determines pilot contamination level on PSS of a synchronization signal block (SSB), depending on different network deployment scenarios. The UE then adaptively perform BM or Sync, by dynamically adjusting to the pilot contamination level on PSS. If the pilot contamination level is high, then the UE follows a 3-symbol mode, e.g., uses only PBCH0, SSS, and PBCH2 symbols for performing BM or Sync. Otherwise, if the pilot contamination level is low, then the UE follows a 4-symbol mode, e.g., uses PSS as an extra symbol for BM or Sync to improve system performance.
