Latest Patents

One of his latest patents is a digital radio communication system utilizing quadrature modulation. This invention aims to achieve spectrum economy while reducing power consumption in transmitters. It also addresses the error rate at receivers and simplifies receiver circuitry. The system quadrature modulates at least one bit stream in a way that the signal points do not trace a path on a complex amplitude plane that passes through the origin. The received signal undergoes hard limiting and frequency discrimination to determine the instantaneous angular velocity. This process allows for the detection of phase variations between consecutive received signals, which are then evaluated against decision threshold levels.

Another notable patent is a rail fastening device. This device features a curved tapered spring with free ends designed to engage a rail flange, preventing lateral and tilting motion of the rail. The spring is secured by a fastening element that includes a detent, which is rotated and slid into a shaped hole in an anchor embedded in the tie supporting the rail.
