  • Patent number: 9188395
    Abstract: The method of manufacturing heat pipe is disclosed to insert a center bar into a metal tube such that the center bar contacts a clearance area of the inner sidewall of the metal tube. Then, the method is to fill the interval between the center bar and the metal tube with powder for sintering. At last, the method is to perform a sintering, extract the center bar, inject working fluid, and close the metal tube. A heat pipe is therefore formed. Because of no sintered powder on the clearance area, the heat pipe can be bent at the clearance area without damaging the capillary structure formed by the sintered powder. The flow path of the working fluid is not interrupted or influenced, so the heat transfer efficiency can be maintained, which overcomes the decrement of the heat transfer efficiency of a bent heat pipe in the prior art.

  • Publication number: 20150276670
    Abstract: The present invention related to an electrochemical biosensing meter, a system and a measuring method for analyte measurement incorporating filled sample detection. The method comprises detecting a third electrical signal obtained from a second electrode pair on a test strip and detecting a second electrical signal obtained from a first electrode pair on the test strip. The second electrode pair is close to a sample entrance of a sample chamber and the first electrode pair is far away from the sample entrance of the sample chamber. The third electrical signal is used for detecting the state of the sample chamber when sufficiently filled. Compare the second electrical signal and the third electrical signal to determine the distribution state of the sample in the sample chamber. Therefore, it increases the credibility for the entire sample chamber sufficiently filled with the sample.

  • Patent number: 9082496
    Abstract: A bit line, which is coupled to a resistive element of a memory cell is set to a first voltage level. The memory cell may be an MRAM cell or an RRAM cell. The resistive element is configured to have a first resistance in a first state of the memory cell and a second resistance in a second state of the memory cell. A source line, which is selectively coupled to the memory cell by an access transistor, is set to a second voltage level. A word line signal is asserted to apply a first bias voltage across the resistive element. The applied first bias voltage initiates a write operation at the memory cell. The word line signal is deasserted after a variable time duration based on a detection, during the write operation, of a current through the resistive element.
