Patent number: 10749495Abstract: An apparatus for acquiring a desired response to an electromagnetic signal includes an adaptive network that receives a feedback signal and dynamically adjusts an electrical characteristic of the adaptive network in response to the feedback signal, the adaptive network electrically cooperating with an electrical component. A measurement device measures a parameter indicative of a combined response by the electrical component and the adaptive network to an impinging electromagnetic signal. A processor identifies, in accordance with the measured parameter, the feedback signal that reduces the difference between a predetermined response and the combined response to the electromagnetic signal. A feedback generator generates the identified feedback signal and conveys the generated feedback signal to the adaptive network.Type: GrantFiled: August 17, 2015Date of Patent: August 18, 2020Assignee: Keysight Technologies, Inc.Inventor: Douglas Baney

Publication number: 20050156100Abstract: An optical position-tracking system comprises an optical device for generating an incident light beam and a reference light beam from a light beam. Moreover, the optical position-tracking system further comprises a light beam steering device for sweeping the incident light beam through an angular range to cause a reflection of the incident light beam by a target, whereas the reflection of the incident light beam is directed to interfere with the reference light beam to form an interference light beam. Additionally, the optical position-tracking system enables determination of a position of the target using an interferometric technique utilizing an angular value of the incident light beam and the interference light beam, whereas the angular value depends on the reflection. If the light beam has a plurality of wavelengths, either due to the existence of these wavelengths simultaneously, or over a time interval having multiple wavelengths, the absolute position of the target can be determined.Type: ApplicationFiled: January 16, 2004Publication date: July 21, 2005Inventors: Tong Xie, Marshall Thomas DePue, Douglas Baney
