Abstract: The present application is applicable to the technical field of image processing, and provides a method and an apparatus for face detection, a terminal device, and a non-transitory computer-readable storage medium. The method includes: obtaining an image to be detected, where a first facial image is contained in the image to be detected; performing an initial detection on the image to be detected to obtain an initial detection result; comparing the first facial image in the image to be detected with a target facial image to obtain a comparison result, if the initial detection result indicates that the initial detection is passed; and determining a final face detection result of the image to be detected according to the comparison result. An accuracy of face detection can be effectively improved by performing the method for face detection.

Abstract: The present solution provides a method for card reading, the method includes: turning on a read head of the magnetic stripe card, a read head of the contact IC card, and a coil of the non-contact IC card; detecting card reading actions; turning off, if the card inserting action is detected, the coil of the non-contact IC card; powering on the card when the card reaches a bottom of a card slot of the payment terminal; controlling, if the card is successfully powered on, the read head of contact IC card to read the card; controlling, if the card fails to be powered on, the read head of the magnetic stripe card to read the card when the card swiping action is detected; and controlling, if the card waving action is detected, the coil of the non-contact IC card to read card.

Abstract: A monitoring method based on the detection of human ingested substances, comprises: acquiring the mass spectrum in the terminal of each matrix assisted laser ionization analysis time-of-flight mass spectrometer, and storing each mass spectrum and its corresponding identity information, sampling time and residence information when sampling in the database; obtaining the mass spectrum characteristic ion peaks of known substances and/or unknown substances in each mass spectrum; and counting the frequency of the mass spectrum characteristic ion peak of the known substance and/or the unknown substance, and early warning of the mass spectrum characteristic ion peak whose frequency is greater than the first threshold.

Abstract: A method for detecting ingestion times comprises the following steps: obtaining hair samples or nail samples; sampling hair samples or nail samples per unit length, and judging whether the target ingested substance and its metabolites are present in each sample; and counting times of detected target ingested substance and its metabolites as the ingestion times.

Abstract: Disclosed are a device and a method for detecting compression and reposition performance of a hydraulic buffer for an elevator. The device includes a laser displacement sensor, a battery charge and power supply circuit and a controller, where the laser displacement sensor is connected to the controller through a signal conditioning and acquisition circuit and a laser emission control circuit; and where the controller is also connected to a memory and a configuration screen, respectively. It can realize the automation of multi-parameter measurement functions of a buffer, such as compression stroke measurement, reposition time measurement and reposition process monitoring (which can reflect whether the reposition process is jammed), and has a high measurement accuracy.
