In a battery pack 10 control section 5 low-power mode, a comparator 81 is used to detect the voltage across a 2.5 m[Omega] current detection resistor 2 connected in the battery 1 charging and discharging path. When the detected voltage exceeds a voltage (2.4 mV) that is lower than the voltage (50 mV) for detecting a 20 A first over-current in the non-low-power mode, that occurrence is recorded in a register 82. When the register 82 holds occurrence of the voltage being exceeded and when a CTRL signal indicating the load device 20 is in the low-power mode is input to an I / O port 55, the control section 5 CPU 51 detects a second over-current of approximately 1 A, switches OFF the cut-off devices 7, and sends advisory data from a communication section 9 to a control and power source section 21 in the load device 20.

The invention relates to a detection method for compatibility of latex paint, in particular to a detection method for compatibility of water-based color paste in the latex paint. The detection method includes the steps that the water-based color paste is added into the latex paint and uniformly stirred to prepare standard sample paint, three standard sample paint samples equal in weight are sampled at will and processed, chromatism values are obtained through card making, detection and calculation, and when all the chromatism values meet the requirement and namely are smaller than 0.5, it is judged that the compatibility of the water-based color paste in the latex paint is up to the standard. The detection method can accurately measure the compatibility of the water-based color paste in the latex paint, and the phenomena of flooding and floating of the latex paint are prevented, and use cost is saved. The detection method is easy to operate, short in time and high in accuracy and eradicates missing detection in a prior use detection method.

The invention relates to the field of unmanned intelligent ships, in particular to a multi-sensor decision-level fusion intelligent ship surface target perception and identification method, comprising an optical camera and a plurality of sensors. Any two or more of , including the following steps, firstly calibrate the internal and external parameters of the sensor; then, according to the target results detected by the navigation radar ARPA target, the AIS target and the lidar, a matching fusion method of multi-sensor target decision-level fusion is designed. The position of the water surface target in the world coordinate system is obtained; finally, the azimuth angle coincidence degree of the image recognition result of the forward-looking camera is used to match the recognition result of the fusion target and the forward dangerous target category. Through the complementary advantages of each sensor, highly robust environment perception and obstacle detection and recognition can be obtained, which provides guarantee for the autonomous navigation of smart ships, collision avoidance and target tracking.

The invention relates to the field of biomedical engineering and provides a method for calibrating an R wave of an electrocardiosignal. The method comprises the following steps: figuring out a difference between a front R wave position and a back R wave position which are adjacent to each other in original electrocardio data, so as to obtain an R wave interval value sequence; figuring out a forward different parameter and a backward difference parameter of the difference between the R wave positions according to the R wave interval value sequence; detecting whether the position of the R wave fails to detect or not according to the size relation of the difference between the front R wave position and the back R wave position which are adjacent to each other; supplementing the position of the R wave failing to detect; detecting whether the position of the R wave is virtually detected or not; and deleting the virtually detected position of the R wave. The invention further provides a device for calibrating the R wave of the electrocardiosignal. According to the invention, through the adoption of a relation between the originally detected R wave positions and an electrocardio data value position relation between the two R waves, leaked detection and virtual detection of the R wave are effectively eliminated.
