摘要: An electro-acoustic transducer (1) is disclosed, comprising a substrate (2) that comprises conducting paths (3), a cover (4) attached to said substrate (2) thus forming an inner chamber (A) and a space (B) outside said chamber (A), wherein said cover (4) comprises one or more ports (5). A MEMS sensor (6) of said transducer (1) has at least one hole (7) extending from a first side (C) to a second side (D). A membrane (8) is arranged in said hole (7) transverse to the hole axis (E) thus forming a first hole space (a) and a second hole space (b). The sensor (6) furthermore has electrical connectors (9) designed to carry electrical signals representing sound acting on said membrane (8), which connectors (9) are connected to said conducting paths (3). According to the invention, said MEMS sensor (6) is arranged inside said chamber (A) in such a way that said second hole space (b) is connected to said outside space (B) via said port or ports (5) and said first hole space (a) is connected to said inner chamber (A).

摘要: Systems and methods for compressive image sensor techniques based on sparse measurement matrices are disclosed. A method to perform compressive sensing (CS) measurement operations for image sensors limits pixel summation to be within neighboring pixels and hence dramatically simplifies CS image sensor circuits and reduces their power consumption while providing better image quality compared to conventional random measurement matrix based methods. A sparse measurement matrix is applied to pixel data to generate a desired number of summation groups, each summation group consisting of outputs from an equal number of pixel cells. Each pair of summation groups contains the same number of shared outputs from pixel cells. From the summation groups, an image captured by the pixel cells is recovered.
