A water quality detection device including a detection tank, a sensor, the cleaner and a processor is provided. The sensor is disposed on the detection tank and is configured to sense a to-be-detected liquid within the detection tank. The cleaner is configured to clean the sensor. The processor is electrically connected to the sensor and the cleaner and is configured to: execute an initialization procedure, which includes driving the sensor to sense the to-be-detected liquid to obtain a number of initial sensing values and calculating a threshold value according to the initial sensing values; drive the sensor to sense the to-be-detected liquid to obtain a sensing value of the to-be-detected liquid, and determine whether the sensing value of the to-be-detected liquid reaches the threshold value; drive the cleaner to operate when the sensing value of the to-be-detected liquid reaches the threshold value.

A thermal image-based temperature measurement calibration method applicable to a thermal image device is provided. The method includes a capturing stage, a processing stage and a calibration stage. During the capturing stage, the thermal image device captures a monitored environment to obtain a measured thermal image. During the processing stage, a processor processes on the measured thermal image to obtain a target information, wherein the target information corresponds to a target in the monitored environment, and the target information includes a target image block and a target measured temperature corresponding to the target image block. During the calibration stage, the processor obtains a distance compensation value according to a pixel number of the target image block, and the processor performs a calibration operation to the target measured temperature at least according to the distance compensation value to obtain a calibrated temperature value corresponding to the target.

A frame timing acquisition system and method are provided including a correlator for comparing a first fixed length subsequence of bits of a received bitstream to a predetermined sync word. A CRC check circuit is provided for, in response to the correlator determining that the first fixed length subsequence of bits matches the predetermined sync word, if a third fixed length subsequence of bits of the bitstream is a cyclical redundancy code parity word formed from a second fixed length subsequence of bits of the bitstream. A decision circuit is also provided for identifying boundaries of a frame of the received bitstream in response to the CRC check circuit determining that the third fixed length subsequence of bits is a cyclical redundancy check parity word of the second fixed length subsequence of bits. According to the inventive method and system, a sync word need be identified in only a single slot of the frame in order to acquire the frame timing.
