Patent number: 11879735Abstract: Systems and methods related to gyroscope related applications. A platform having at least one torus shaped channel that is filled with a liquid is used in conjunction with at least one marker to determine the direction of forces applied to the platform. Each marker is neutrally buoyant within the liquid and a marker tracking system is used to determine the displacement of the marker from its resting place after a force has been applied to the platform. The tracking system may be based on at least one digital camera in conjunction with suitable image processing software to determine the marker's position before, during, and after the force has been applied. A gyroscope can be constructed using three such platforms with each platform being orthogonal to the other two. Each platform may have multiple concentric channels with a common center with each channel having a different sensitivity to the applied forces.Type: GrantFiled: January 23, 2020Date of Patent: January 23, 2024Assignee: UTI LIMITED PARTNERSHIPInventors: Ahmed Youssef, Naser El-Sheimy

Patent number: 11754590Abstract: Systems and methods relating to sensors for measuring acceleration. Two attached containers are each filled with different liquids. At each junction of the two liquids, an indicator is placed. When acceleration forces are applied to the sensor, the indicator moves when the boundary between the two liquids similarly move. The amount of movement of the boundary and of the indicator is proportional to the amount of acceleration for applied. A tracking subsystem tracks the position of the indicator and, by determining the amount of movement of the indicator, the amount of acceleration force applied can be calculated. The indicator can be a particle or it can be a beam-like element that deflects when the boundary between the two liquids move.Type: GrantFiled: January 24, 2020Date of Patent: September 12, 2023Assignee: UTI LIMITED PARTNERSHIPInventors: Ahmed Youssef, Naser El-Sheimy

Publication number: 20230254003Abstract: Certain aspects of the present disclosure provide techniques and apparatus for calibrating radio frequency (RF) circuits using machine learning. One example method generally includes calibrating a first subset of RF circuit calibration parameters. Values are predicted for a second subset of RF circuit calibration parameters based on a machine learning model and the first subset of RF circuit calibration parameters. The second subset of RF circuit calibration parameters may be distinct from the first subset of RF circuit calibration parameters. At least the first subset of RF circuit calibration parameters is verified, and after the verifying, at least the first subset of RF circuit calibration parameters are written to a memory associated with the RF circuit.Type: ApplicationFiled: March 22, 2023Publication date: August 10, 2023Inventors: Lindsey Makana KOSTAS, Rishubh KHURANA, Ahmed YOUSSEF, Francisco LEDESMA, Sergey MURASHOV, Viral RANPARA, Enrique DE LA ROSA, Ming LEUNG, Gurkanwal Singh SAHOTA, Shahnaz SHIRAZI

Patent number: 11444376Abstract: Systems and methods for performing calibration of antenna arrays with dual-polarization antenna elements are disclosed. An example system includes an antenna array and a calibration circuitry. The antenna array includes a plurality of antenna cells arranged in K rows and L columns, each cell including a plurality of dual-polarization antenna elements. Antenna cells in columns 1 through Y form a first sub-array, while antenna cells in columns Y+1 through L form a second sub-array. The calibration circuitry is configured to perform calibration by individually calibrating each column of antenna cells of the first sub-array, calibrating different columns of antenna cells of the first sub-array with respect to one another, individually calibrating each column of antenna cells of the second sub-array, calibrating different columns of antenna cells of the second sub-array with respect to one another, and calibrating antenna elements of the first and second sub-arrays with respect to one another.Type: GrantFiled: June 5, 2020Date of Patent: September 13, 2022Assignee: ANALOG DEVICES INTERNATIONAL UNLIMITED COM PANYInventors: Mohamed Ahmed Youssef Abdalla, Islam Eshrah, Ahmed Ibrahim, Ahmed Mehana

Patent number: 11349208Abstract: An antenna apparatus for calibrating one or more of a plurality of antenna elements of an antenna array using one or more probes is disclosed. The apparatus includes an upconverter and/or downconverter (UDC) circuit and a calibration arrangement that includes a switching circuit. The switching circuit is configured to enable operation of the UDC in a first mode or in a second mode.

Patent number: 11277108Abstract: An example VGA includes a transistor arrangement having a plurality of transistors configured to realize one or more gain step circuits of the VGA, and a cross-couple switching arrangement having a plurality of switches configured to selectively change the coupling of the terminals of at least some of the transistors depending on whether a given gain step circuit is supposed to be in an ON state or in an OFF state. Using the cross-couple switching arrangement advantageously allows keeping all of the transistors ON at all times during operation and changing the coupling of some transistor terminals to either realize an in-phase addition of currents flowing through various transistors to apply the maximum gain or realize a subtraction of currents to apply the minimum gain. Such a VGA may be inherently wideband, enabling a highly linear, wideband operation without having to resort to significant trade-offs with other performance parameters.Type: GrantFiled: December 28, 2020Date of Patent: March 15, 2022Assignee: ANALOG DEVICES INTERNATIONAL UNLIMITED COMPANYInventors: Yahia Z.
