  • Patent number: 11009534
    Abstract: Embodiments of the present invention relate to water leakage detection. Data obtained by a smart electricity meter during a predefined time period is collected, where the smart electricity meter is associated with a water-consuming unit. Usages of certain electric appliances in the water-consuming unit during the predefined time period are determined based on the collected data. The electricity consumption of those appliances is correlated to water consumption. The legitimate water consumption of the water-consuming unit during the predefined time period is then determined based on the usages of the electric appliances.

  • Patent number: 10316356
    Abstract: Provided is a method of constructing a sequencing library using an adaptor element in a bubble shape. The bubble-shaped adaptor is ligated to a DNA fragment respectively at the 3?-terminal and the 5?-terminal i.e., two bubble-shaped adaptors with same sequences are ligated in one step. The bubble-shaped adaptor-ligated product is then amplified with a primer complementary to the 3?-terminal of the long-chain nucleic acid of the bubble-shaped adaptor, so as to replace the non-paired sequence in the short-chain nucleic acid.
