Title: Christopher John Leskiw: Innovator in Imaging Systems

Introduction

Christopher John Leskiw is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of imaging systems, holding a total of 2 patents. His work focuses on advanced technologies that enhance imaging capabilities and improve transmitter performance.

Latest Patents

Leskiw's latest patents include an "Imaging system and method using improved modulated excitation." This innovative imaging system utilizes deterministic bit sequences modulated onto an in-phase component of a carrier frequency. The system continuously transmits signals via a transducer, which are then received for imaging a medium or environment. The received signal is demodulated by both an in-phase demodulator and a quadrature demodulator. The processed demodulated components provide a spatial mapping of the medium or environment being imaged.

Another significant patent is the "Adaptive controller for linearization of transmitter." This invention employs a bank of complex gain elements to create a step-wise approximation of an arbitrary complex-gain predistortion function for a nonlinear transmitter. The adaptive loop is closed between the input of the gain bank and the output of the transmitter through a linear receiver. The adaptive controller consists of a bank of proportional-integral (PI) controllers that manage the real and imaginary parts of each predistortion gain element.
