Abstract: Provided are a method and device for recognizing hook effect in immune turbidimetry, and a computer readable medium. This method generates a reaction curve using light signals measured in a predetermined time period by immune reaction of analyte in a sample, and uses distribution information of the reaction curve in the predetermined time period to determine whether the sample has hook effect. This method only uses measurement information of a small predetermined time period in entire reaction time to determine whether a sample has hook effect, and terminates the test in time, thus accelerating the speed of immune turbidimetry detection of samples with hook effect.

Abstract: An object attribute inference method, a storage medium and an electronic device. The method includes the following steps: training a preset neural network by using a training sample comprising an action sequence and a target object attribute tag; where the action sequence is an interactive action sequence of a human body and an object. In this way, the object attribute inference model obtained through training can recognize the object attributes from the interaction action of the human body and the object, the object attributes include and are not limited to the weight, the shape, the hardness degree and the like of the object, and therefore the inference module obtained through training has the advantages of being universal in object attribute inference and wide in application range.

Abstract: A biological identification safe deposit box includes a lock. The lock includes a first elastic lock catch, a first connecting rod, a second elastic lock catch, a second connecting rod, a transmission rotating disc, a driving motor, and a motor controller. A movable groove is defined in a center of the transmission rotating disc. A movable end of the driving motor extends into the movable groove. A driving block is disposed on a side surface of the movable end of the driving motor. A semi-annular adjusting groove, with respect to the driving block, is defined on an inner wall of the movable groove. An idle stroke exists when the driving block moves in the semi-annular adjusting groove. The lock further includes an emergency unlocking assembly. The emergency unlocking assembly drives the transmission rotating disc to rotate. The emergency unlocking assembly and the transmission rotating disc are separately disposed.
