  • Patent number: 10293287
    Abstract: In the water filter assembly, the flow path could be changed to the bypass flow path or the purified water flow path, when the inner moves upwardly and downwardly in the filter head by combining or separating of the filter body and filter head. The inner is movably inserted to the filter head. The elastic member changes the flow path to bypass flow path when the filter body is separated by elastic biasing the inner between the filter head and the inner to downward direction of the filter head. If the user pushes the inner to the inside of the filter head by mistake when the filter body is separated from the filter head, the inner is pushed out to be the original position, so that the filter body can be rapidly combined to the filter head including the inner.

  • Patent number: 9261555
    Abstract: To measure an inner temperature of a chamber included in a test handler, self-refresh currents of semiconductor memory devices under test are measured. The semiconductor memory devices are disposed in the chamber and have a function of linear temperature compensated self-refresh (Li-TCSR). Local temperature values are generated based on the self-refresh currents, where each local temperature value indicates a temperature near the corresponding semiconductor memory device of the semiconductor memory devices under test.
