Abstract: A method for detecting an object includes providing respective spatial coordinates relating to a multiplicity of reflection signals of a frame of a radar sensor system and providing a measurement attribute of a first portion of the multiplicity of reflection signals. The respective spatial coordinates of the multiplicity of reflection signals are transformed into an occupancy grid. An occupancy grid is generated with the multiplicity of reflection signals being spatially represented in the occupancy grid by mapping the respective spatial coordinates of the multiplicity of reflection signals in the occupancy grid and assigning the respective first measurement attribute of the multiplicity of reflection signals to the spatial representation of the multiplicity of reflection signals. An input tensor is generated using the occupancy grid for a trained neural network for detecting the at least one object. The object is detected using the input tensor and the trained neural network.

Abstract: A refrigerator includes a box body, a hinge assembly, and a door body. The hinge assembly includes a plate body, a locking hook, and a blocking portion. A free end of the locking hook extends in a direction away from the plate body and is bent in a direction proximate to the plate body, so as to form an opening toward the plate body. In a case where the door body is in a closed state, the blocking portion is located in the opening. During a process from closing to opening of the door body, the locking hook is deformed under force to be disengaged from the blocking portion and unlocked.

Abstract: A matrix storage method and apparatus are provided. In the method, a plurality of first sub-blocks corresponding to a to-be-stored original matrix are obtained. The plurality of first sub-blocks are obtained after blocking is performed on the original matrix by using a sub-block with a scale of M1×N1 as a unit and a non-zero element in each submatrix obtained through blocking is compressed in a specified direction, where M1 and N1 are positive integers. Blocking is performed on each first sub-block by using a sub-block with a scale of M2×N2 as a unit to obtain a plurality of second sub-blocks, where M2 is a positive integer not greater than M1, and N2 is a positive integer not greater than N1. Data of the plurality of second sub-blocks is sequentially stored by using a second sub-block as a unit.
