Title: Innovations of Leo Laughlin
Introduction
Leo Laughlin is a notable inventor based in Bristol, GB. He has made significant contributions to the field of signal processing and interference cancellation. With a total of four patents to his name, Laughlin's work showcases his expertise and innovative spirit.
Latest Patents
Among his latest patents are the "Active interference cancellation apparatus" and "signal isolation control apparatus and method of actively cancelling interference." This apparatus includes a receiver chain with an input node and a transmitter chain comprising a tap and output nodes. An auxiliary transmitter chain is also included, which features an auxiliary input node coupled to the tap node, an adaptive filter unit, and a signal output linked to the input node. The filter unit consists of an interpolation processor, an adaptive filter, and a coefficient processor connected to the receiver chain and the adaptive filter. The transmitter chain generates a first waveform that comprises a plurality of frequency-separated signals. Simultaneously, the auxiliary chain applies a second waveform that includes another set of frequency-separated signals at the input node. The receiver chain then receives a composite waveform that combines a waveform from the output node and the second waveform. Notably, the first waveform lacks signals necessary for determining the coefficients of the filter whose frequencies coincide with the second waveform's signals.
Another significant patent is the "Methods and apparatus for duplexing signals." This duplexing apparatus features a reference of impedance settings and corresponding calibration measurements. A controller is designed to set a variable impedance to a first impedance setting, transmit a first signal at a first frequency, and measure the resulting signal at an output node of a hybrid circuit. The controller subsequently selects a second impedance setting, transmits a second signal at a second frequency, and measures the resulting second signal. The controller then determines a balancing result using a system of equations that associate the first and second measured signals with the first and second calibration measurements from the reference.
