International Classification:

G10K 11/04
G05B 13/02
G10K 11/00

US Classification:

Abstract:

Methods for modeling the secondary path of an ANC system to improve convergence and tracking during noise control operation, and their associated uses are provided. In one aspect, for example, a method for modeling a secondary path for an active noise control system is provided. Such a method may include receiving a reference signal, filtering the reference signal with an initial secondary path model to obtain a filtered reference signal, calculating an autocorrelation matrix from the filtered reference signal, and calculating a plurality of eigenvalues from the autocorrelation matrix. The method may further include calculating a maximum difference between the plurality of eigenvalues and iterating a test model to determine an optimized secondary path model having a plurality of optimized eigenvalues that have a minimized difference that is less than the maximum difference of the plurality of eigenvalues, such that the optimized secondary path model may be utilized in the active noise control system.

International Classification:

G01F 174

US Classification:

7386104, 73592

Abstract:

A non invasive method and apparatus is provided to measure the mass flow rate of a multi-phase fluid. An accelerometer is attached to a pipe carrying a multi-phase fluid. Flow related measurements in pipes are sensitive to random velocity fluctuations whose magnitude is proportional to the mean mass flow rate. An analysis of the signal produced by the accelerometer shows a relationship between the mass flow of a fluid and the noise component of the signal of an accelerometer. The noise signal, as defined by the standard deviation of the accelerometer signal allows the method and apparatus of the present invention to non-intrusively measure the mass flow rate of a multi-phase fluid.

International Classification:

A47C 21/00
A61M 21/02

Abstract:

A system for introducing vibrational waves into a body of a subject to treat sleep disorders is provided. The system includes a bed frame having a first vibration contact and a second vibration contact. The first vibration contact is in mechanical communication with a first location of the body of the subject, and the second vibration contact is in mechanical communication with a second location of the body of the subject. A first vibration source is connected to the first vibration contact and configured to cause a first vibration of the first vibration contact. A second vibration source is connected to the second vibration contact and configured to cause a second vibration of the second vibration contact. The location or orientation of the first vibration contact and the second vibration contact are configured such that the first vibration combines with the second vibration to generate a super-imposed vibration.

International Classification:

A61H 15/02
A61H 23/02

Abstract:

A spherical manual and electromechanically-operated spherical massage implement is disclosed which facilitates the even application of pressure to the body tissue of a client during massage therapy, including tendons, ligaments, and muscles (e.g. the gluteus maximus, gluteus medius, and the like). Variations of the disclosed implement comprise vibrating and heating functions. The disclosed invention relieves sore and achy muscles, helps blood circulation, relieving muscle cramps, loosening tight and knotted muscles, and relieving pressure from the massage therapist's hands.
