  • Publication number: 20240163957
    Abstract: A method performed by an apparatus in a non-radio resource control (RRC) connected state includes performing a first RRC connection resume procedure for a radio access network-based notification area update in response to a first preset condition being met. The first preset condition includes determining that a first timer does not run and a second timer expires, or the first preset condition includes determining that the apparatus receives a system information block 1 of a first serving cell, the first serving cell does not belong to a configured radio access network-based notification area, and the first timer does not run, and the first timer is started in response to the apparatus initiating a second RRC connection resume procedure for small data transmission, and the second timer is started in response to the apparatus receiving a RRC release message comprising a duration of the second timer.

  • Publication number: 20240110933
    Abstract: Provided is a method for detecting ammonia nitrogen content by using a nitrification biological reaction. In the present disclosure, the nitrifying microorganisms have high specificity for ammonia nitrogen, a metabolism and oxygen consumption capacity closely related to the ammonia nitrogen concentration, high accuracy and high sensitivity of ammonia nitrogen detection, and are not easily disturbed by water body chromaticity, suspended matters, and the like. In addition, the activity of the nitrification microorganism membrane reactor can be kept stable for a long term, and the stability of a sensor is good for long-term use. In the present disclosure, with a mono-component or multi-component solution containing inorganic nitrogen and inorganic carbon as a nitrification nutrient solution, a nitrification microorganism membrane with strong adaptability to the environment, a stable structure, a high selectivity for ammonia nitrogen, and an ability of efficiently degrading ammonia nitrogen can be obtained.

  • Patent number: 11914515
    Abstract: A cache memory device is provided in the disclosure. The cache memory device includes a first AGC, a compression circuit, a second AGC, a virtual tag array, and a comparator circuit. The first AGC generates a virtual address based on a load instruction. The compression circuit obtains the higher part of the virtual address and generates a target hash value based on the higher part of the virtual address. The second AGC generates the lower part of the virtual address based on the load instruction. The virtual tag array obtains the lower part and selects a set of memory units. The comparator circuit compares the target hash value to a hash value stored in each memory unit of the set of memory units. When the comparator circuit generates the virtual tag miss signal, the comparator circuit transmits the virtual tag miss signal to the reservation station.
