Title: Allen K Lo: Innovator in Noise Cancellation and Tracking Technologies
Introduction
Allen K Lo is a distinguished inventor based in Diamond Bar, CA (US). He has made significant contributions to the fields of noise cancellation and tracking technologies, holding a total of 7 patents. His innovative work has advanced the capabilities of various detection and noise reduction systems.
Latest Patents
Among his latest patents is the "Multiple Adaptive Filter Active Noise Canceller." This invention is an active adaptive noise canceller that operates without requiring a training mode and functions over an extended noise bandwidth. The canceller partitions the noise bandwidth into frequency sub-bands, employing multiple adaptive filter channels to cancel noise energy in each respective sub-band. Each channel includes bandpass filters to restrict its operation to a specific sub-band, with delays inserted for filter weight updating. This design ensures stability over each sub-band, allowing the canceller to effectively operate across the entire extended noise bandwidth.
Another notable patent is the "Three-Dimensional Maximum A Posteriori (MAP) Tracking." This automatic detection apparatus utilizes the Short and Toomey algorithmic processing procedure to analyze a time, frequency, and beam direction windowed set of Fast Fourier Transform (FFT) magnitude detected data. The invention enhances tracking capabilities from two dimensions to three dimensions, providing spatial tracking alongside spectral tracking. This advancement is achieved by processing individual target tracks associated with each beam direction concurrently, resulting in improved detection of targets.
