Abstract: The invention is notably directed to a method of in-memory processing, the aim of which is to perform matrix-vector calculations. The method relies on a device having a crossbar array structure (15). The latter includes N input lines (152) and M output lines (153), which are interconnected at cross-points defining N×M cells (155), where N?2 and M?2. The cells include respective memory systems, each designed to store K weights Wi,j,k, where K?2. Thus, the crossbar array structure includes N×M memory systems, which are capable of storing K sets of N×M weights. In order to perform multiply-accumulate (MAC) operations, the method first enables N×M active weights for the N×M cells by selecting, for each of the memory systems, a weight from its K weights and setting the selected weight as an active weight. Next, signals encoding a vector of N components are applied to the N input lines of the crossbar array structure. This causes the latter to perform MAC operations based on the vector and the N×M active weights.

Abstract: The present invention is directed to a camera lens filter assembly including a camera lens filter and an included optical component. The optical component is installed on an optic mounting part; and a clamp is mounted on a clamp mounting part, so the clamp can press to tighten against the optical component for the purpose of assembly. The present invention efficiently prevents air, dust and other environmental pollutants from reaching the front surface of the camera lens and will also seal to secure the camera lens filter to the camera lens barrel in a way that it will not dismount itself due to vibration, use or other operating conditions.
