Abstract: The MEMS gyroscope is formed by a substrate, a first mass and a second mass, wherein the first and the second masses are suspended over the substrate and extend, at rest, in a plane of extension defining a first direction and a second direction transverse to the first direction. The MEMS gyroscope further has a drive structure coupled to the first mass and configured, in use, to cause a movement of the first mass in the first direction, and an elastic coupling structure, which extends between the first mass and the second mass and is configured to couple the movement of the first mass in the first direction with a movement of the second mass in the second direction. The elastic coupling structure has a first portion having a first stiffness and a second portion having a second stiffness greater than the first stiffness.

Abstract: An efficient reduction for the time delay during echo correction in a telecommunications network is made possible by a method for reducing an echo in uplink data (19 to 22) that are issued from a terminal (2, 3) of a telecommunications network (6, 8). A copy (25) of downlink data is created from downlink data (13) that are to be transmitted from the telecommunications network (6, 8) toward the terminal (3). Said copy (25) of downlink data is converted (transcoder 18) and used for the reduction (10) of echo in uplink data (21), whereas downlink data (13) are transmitted (6) toward the terminal (2, 3).

Abstract: Disclosed is a method for suppressing (10) echo (z(t)) in uplink data (y(t), 12-16) originating from a terminal (2, 3), said method allowing a delay and a decrease in quality during echo suppression of uplink data originating from a wireless terminal (2, 3). According to the inventive method, original or copied downlink data (12-16) and uplink data (19-21) are analyzed in order to prepare echo suppression (10), and uplink data (19-21) is modified in the compressed state in order to reduce echo (10) by using the results of said analysis (9) of the downlink data (12-16) and uplink data (19-21).
