Abstract: A method and system are provided in which a device, such as an acoustic echo canceller, may reduce the residual echo that may be heard at the far end of a conversation when an external speaker volume is changed. The device may compute a gain based on an echo estimate produced by a filter and on a near-end signal comprising audio information. The gain may be based on a correlation of the echo estimate and the near-end signal that tracks the changes in volume. Once computed, the gain may be validated to ensure that it is being applied when appropriate. The echo estimate may be adjusted by first applying the gain to an output of the filter and subsequently scaling a value of each of the coefficients of the filter based on the gain. The gain may be smoothed out over consecutive frames based on several adaptation schemes.

Abstract: The present invention relates to a gripping and transport clamp mounted at an end of a robotic arm. The clamp has a support member mounted at the end of the robotic arm and two lower pressing plates and one upper pressing plate mounted on the support member. A sensor is used to detect a reaction force being exerted on the first pressing plate upon displacement thereof. An actuator inserts the first lower pressing plate under the object to be gripped in response to a detection of the reaction force by the sensor. The second lower pressing plate under the first pressing plate moves between a retracted position and an extended position by means of an actuator mounted between the second lower pressing plate and the support member. It is also inserted under the object to be gripped. An actuator moves the upper pressing plate towards the object for gripping it between the plates. A controller receives detection signals from the sensor and operates the actuators.
