Tuned Feedforward Lms Filter With Feedback Control

View page
US Patent:
20040264706, Dec 30, 2004
Filed:
May 10, 2004
Appl. No.:
10/842714
Inventors:
Laura Ray - Hanover NH, US
Alexander Streeter - Rochester NY, US
International Classification:
A61F011/06
G10K011/16
H03B029/00
US Classification:
381/071110, 381/071120
Abstract:
A method to automatically and adaptively tune a leaky, normalized least-mean-square (LNLMS) algorithm so as to maximize the stability and noise reduction performance in feedforward adaptive noise cancellation systems. The automatic tuning method provides for time-varying tuning parameters and that are functions of the instantaneous measured acoustic noise signal, weight vector length, and measurement noise variance. The method addresses situations in which signal-to-noise ratio varies substantially due to nonstationary noise fields, affecting stability, convergence, and steady-state noise cancellation performance of LMS algorithms. The method has been embodied in the particular context of active noise cancellation in communication headsets. However, the method is generic, in that it is applicable to a wide range of systems subject to nonstationary, i.e., time-varying, noise fields, including sonar, radar, echo cancellation, and telephony. Further, the hybridization of the disclosed Lyapunov-tuned feedforward LMS filter with a feedback controller as also disclosed herein enhances stability margins, robustness, and further enhances performance.

N. Christopher Perry - Manchester NH, US
Assignee:
DEKA Products Limited Partnership - Manchester NH
International Classification:
A61F 5/00
US Classification:
602 5
Abstract:
A control unit system. The system includes a control unit which includes a control unit charging interface, at least one magnet located proximate to the control unit charging interface, at least one actuator, a detachable manifold including at least one magnet, fluidly coupled to the at least one actuator, a pump connected to the at least one actuator for causing actuation thereof, and a control system for controlling the pump, wherein the control system controls the pump to actuate the at least one actuator at least in response to a signal received by the control system. The system also includes a recharging device configured to receive the control unit, the recharging device including a reed switch, wherein when the magnet in the control unit is located proximate to the reed switch, the switch is activated.
