Abstract: Disclosed are a filter element for liquid filtration and a filter. The filter element includes a ring filter medium, first and second end caps connected to the ring filter medium, and a ventilation assembly, where the ring filter medium has a central cavity formed around a central axis thereof; the ventilation assembly is disposed in the central cavity; and an intercepting ring groove is formed at a ring seal. In this technical solution, a sealing O-ring at a sealing part of the filter element and the housing assembly is replaced with the ring seal with a self-sealing function, which has a better sealing effect under an oil pressure and can reduce a compression amount; and while oil dirt is intercepted, the disassembly of the filter element is not affected, and especially under effective exhaust of the ventilation assembly, the disassembly is more labor-saving.

Abstract: Disclosed are techniques for positioning. A receiver receives complementary timing information associated with the positioning reference signals (PRS) of a repetition of a PRS sequence. The complementary timing information distinguishes a repetition of a PRS sequence from remaining repetitions of the PRS sequence. Based on the complementary timing information associated with different PRS from different non-terrestrial vehicles indicating that the PRS were transmitted during the same radio frame, the receiver can determine an observed time difference of arrival (OTDOA) between the PRS received from the respective non-terrestrial vehicles.
