Abstract: A method and an apparatus for detecting a relative location between devices is disclosed. The detection method includes: obtaining a first target audio signal obtained by a first microphone of a device B; determining a first audio segment and a second audio segment based on a first target moment and the first target audio signal, where the first target moment is a moment determined in the first target audio signal based on a target amplitude; separately searching for the first audio segment and the second audio segment to obtain a first arrival moment and a second arrival moment; and determining a relative location between a device A and the device B based on the first arrival moment and the second arrival moment.

Abstract: Methods of producing compounds and combinatorial compound libraries, the compounds and libraries produced via the methods are provided, and methods of using the libraries to identify compounds having a desired property, such as a desired biological activity and the compounds identified using these methods are provided.
