Patent number: 12007472Abstract: A digital direct line-of-sight (DLOS) intermediate frequency (IF) signal of a DLOS component of an RF carrier signal transmitted by a transmitter located above the surface of the earth and a digital reflected IF signal of a reflected component of the carrier signal that is reflected from a specular point (SP) on the surface of the earth are received. Modeled reference signal parameters are generated using the digital DLOS IF signal and known locations of one or more receiving antennas, the transmitter, and the SP. A reference signal is generated based on the modeled reference signal parameters and feedback of a previously estimated ??. The reference signal is correlated with the digital reflected IF signal to produce in-phase (I) and quadrature-phase (Q) correlation results. An estimated C/N0 and an estimated ?? for the digital reflected IF signal are calculated from the correlation results.Type: GrantFiled: June 21, 2023Date of Patent: June 11, 2024Assignee: The Regents of the University of ColoradoInventors: Yang Wang, Yu T.

Patent number: 12003175Abstract: A hybrid converter achieves high efficiency with an inductor positioned at the lower current path that significantly decreases inductor loss by having the DC component of inductor current reduced. The circuit also features reduced inductance requirement by reducing the voltage swing blocked by the inductor. As a result, it turns to benefit of both efficiency improvement and better integration. Less voltage stress for switches is also an important advantage to switching loss reduction and switching frequency increase which in turns enables passive component size reduction. The circuit in this invention can be realized for both step-down and step-up power conversion as well as bidirectional power flow is available. For simplicity and cost, some of switches can be replaced with passive switches such as diodes which highly simplifies the converter circuit implementation.Type: GrantFiled: May 31, 2017Date of Patent: June 4, 2024Assignee: The Regents of the University of Colorado, a body corporateInventors: Gabsu Seo, Hanh-Phuc Le

Patent number: 11994533Abstract: Infrared (IR) vibrational scattering scanning near-field optical microscopy (s-SNOM) has advanced to become a powerful nanoimaging and spectroscopy technique with applications ranging from biological to quantum materials. However, full spatiospectral s-SNOM continues to be challenged by long measurement times and drift during the acquisition of large associated datasets. Various embodiments provide for a novel approach of computational spatiospectral s-SNOM by transforming the basis from the stationary frame into the rotating frame of the IR carrier frequency. Some embodiments see acceleration of IR s-SNOM data collection by a factor of 10 or more in combination with prior knowledge of the electronic or vibrational resonances to be probed, the IR source excitation spectrum, and other general sample characteristics.Type: GrantFiled: November 25, 2020Date of Patent: May 28, 2024Assignee: The Regents of the University of Colorado, a body corporateInventors: Rafael Piestun, Simon Labouesse, Markus B.

Patent number: 11993635Abstract: This invention relates to the field of genetic engineering. Specifically, the invention relates to the construction of operons to produce biologically active agents. For example, operons may be constructed to produce agents that control the function of biochemical pathway proteins (e.g., protein phosphatases, kinases and/or proteases). Such agents may include inhibitors and modulators that may be used in studying or controlling phosphatase function associated with abnormalities in a phosphatase pathway or expression level. Fusion proteins, such as light activated protein phosphatases, may be genetically encoded and expressed as photoswitchable phosphatases. Systems are provided for use in controlling phosphatase function within living cells or in identifying small molecule inhibitors/activator/modulator molecules of protein phosphatases associated with cell signaling.Type: GrantFiled: August 2, 2022Date of Patent: May 28, 2024Assignee: THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATEInventors: Jerome Fox, Ankur Sarkar, Akarawin Hongdusit, Edward Kim

Patent number: 11986963Abstract: Systems and methods for human-robot communication are proved. More particularly, some embodiments use augmented reality to facilitate communication of robot intention and teleoperation in human-robot cooperative environments. Various embodiments of the present technology provide a middleware that integrates augmented reality (AR) with novel teleoperation interfaces to increase operation effectiveness, support the user in conducting concurrent work, and decrease stress. Various embodiments provide predictive graphical interfaces such that a teleoperator controls a virtual robot surrogate, rather than directly operating the robot itself, providing the user with foresight regarding where the physical robot will end up and how it will get there. In accordance with various embodiments a user may select between two AR interfaces using such a surrogate: one focused on real-time control and one inspired by waypoint delegation.Type: GrantFiled: March 5, 2019Date of Patent: May 21, 2024Assignee: The Regents of the University of ColoradoInventors: Daniel Szafir, Michael E.
