4results about How to "Prevent false detection" patented technology

This utility model relates to a testing device, and more particularly to a bottled water quality testing device, comprising a housing, a controller, a first conveyor belt, a testing probe, a fixing frame, and absorbent cotton, etc. The first conveyor belt is located at the bottom of the housing, and a moving mechanism is installed on the inner wall of the housing. The testing probe is connected to the moving mechanism. The controller is installed on one side of the housing, and the testing probe is electrically connected to the controller. A fixing frame is fixedly connected to the side of the housing opposite to the moving mechanism, and a liquid storage frame is slidably connected to the fixing frame. In this utility model, the testing probe is wiped and disinfected with absorbent cotton and disinfectant alcohol, ensuring the cleanliness and hygiene of the testing probe. Simultaneously, the alcohol on the surface of the testing probe evaporates on its own, reaching a dry state, providing a guarantee for subsequent testing work and ensuring the accuracy of the testing.

This invention relates to an insulation monitoring device, comprising: a signal generation unit that generates a measurement signal having a preset voltage and applies the measurement signal to ground through a protective conductor connected to one end of the signal generation unit; a coupling resistor connected to the transmission line; a signal detection unit that includes a detection resistor disposed between the coupling resistor and the other end of the signal generation unit, and detects the voltage of the measurement signal distributed in the internal resistance of the insulation monitoring device formed by the coupling resistor and the detection resistor based on the voltage difference across the detection resistor; and a control unit that detects transient voltages caused by the charging and discharging of a system capacitor formed by parasitic capacitance between the transmission line and the ground from the voltage detected by the signal detection unit, and confirms the connection status of the insulation monitoring device to the transmission line and the ground based on the result of detecting the transient voltage.

The utility model is used for the missed pasting detection of FPC reinforcing plate, two detection windows are opened in the first side surface of FPC, a connecting circuit is provided between the two detection windows, the first side surface of FPC is used for pasting transparent reinforcing plate, the four peripheral edges of transparent reinforcing plate are located within the four peripheral edge range of FPC, and the FPC transparent reinforcing missed pasting detection device comprises a resistance detection device and two probes, the two probes are electrically connected with the resistance detection device, a loop is formed between the two probes and the resistance detection device when the two probes are short-circuited, and the probe is used for aligned insertion into the detection window for missed pasting detection.

This disclosure relates to a stop line detection device that, based on images captured by a front camera of its own vehicle, identifies the boundary lines of the road and lanes in which the vehicle travels, and detects the stop line at an intersection ahead of the vehicle. The stop line detection device comprises: an intersection area detection unit set within the road in which the vehicle travels, corresponding to the intersection area; a pedestrian crossing detection unit that detects pedestrian crossings within the intersection area; a stop line search area setting unit set within the lane in which the vehicle travels, extending from the pedestrian crossing towards the vehicle; and a stop line detection unit that detects stop lines within the stop line search area, wherein the depth of the stop line search area in the direction of extension of the driving lane is less than twice the depth of the pedestrian crossing.
