Abstract: The present invention provides a micro biosensor for reducing a measurement interference when measuring a target analyte in the biofluid, including: a substrate; a first working electrode configured on the surface, and including a first sensing section; a second working electrode configured on the surface, and including a second sensing section which is configured adjacent to at least one side of the first sensing section; and a chemical reagent covered on at least a portion of the first sensing section for reacting with the target analyte to produce a resultant. When the first working electrode is driven by a first working voltage, the first sensing section measures a physiological signal with respect to the target analyte. When the second working electrode is driven by a second working voltage, the second conductive material can directly consume the interferant so as to continuously reduce the measurement inference of the physiological signal.

The first electrode is disposed on the substrate and used as a counter electrode. The second electrode is disposed on the substrate and spaced apart from the first electrode. The third electrode is disposed on the substrate and used as a working electrode. The chemical reagent layer at least covers a sensing section of the third electrode so as to permit the third electrode to selectively cooperate with the first electrode or the first and second electrodes to measure a physiological signal in response to the physiological parameter of the analyte.

Abstract: A method to avoid over-rebooting of a power supply device comprises Step 1: receiving a power-good signal generated by a power supply device working normally; Step 2: checking whether the power-good signal is received; if no, demanding the power supply device to reboot; and Step 3: recording a count of rebootings of the power supply device; after the power supply device reboots, checking again whether the power-good signal is received; if yes, letting the power supply device keep on working and resetting the count of rebootings; if no, demanding the power supply device to reboot again, accumulating the count of rebootings, and checking whether the count of rebootings is greater than a limited count of rebootings; if yes, forbidding the power supply device to reboot. Thus is solved the problem that a power supply device whose abnormality cannot be removed by rebooting may damage the information device.

Abstract: A damage identification method for a redundant power supply system is disclosed. The redundant power supply system comprises a plurality of power supply devices and a control unit. In application of the method, the control unit respectively sends switching signals to the power supply devices to boot every power supply device. The control unit checks whether each of the power supply devices sends back a power state signal. If at least one power supply device does not sends back the power state signal, the control unit resends the switching signal to the power supply device to compulsorily reboot the power supply device, which does not output the power state signal. Thereby is solved the problem that the conventional technology cannot instantly exclude temporary abnormalities and causes the user to misjudge the failure of a power supply device.

Upon receiving the power-off signal, the power supply device deactivates the main power supply module, but reactivates the standby power supply module so that the standby power supply module outputs the standby power to the motherboard.
