Abstract: Methods for measuring crosstalk in an electronic circuit having multiple ports comprises determining two ports of interest of the electronic circuit, in which crosstalk will be measured between. Furthermore, the method includes determining one or more ports of the electronic circuit to be terminated, independent from the ports of interest, so that signals of these ports do not interfere with measuring crosstalk between the two ports of interest. To terminate the ports determined to be terminated, a piece of absorber sheet is used to cover the ports determined to be terminated. Pressure is applied to the piece of absorber sheet such that the piece of absorber sheet makes a good contact and absorbs signals traveling into the ports determined to be terminated, thereby terminating the ports determined to be terminated so that crosstalk between the two ports of interest may be effectively measured.

Abstract: The present invention is broadly concerned with mineralization methods that assist in permanent carbon storage. The methods provide a storage mechanism for oxalic acid generated by existing or future-developed carbon capture and conversion methods that convert CO2 to oxalic acid. That oxalic acid can be injected into a subsurface rock formation containing non-carbonate rock to form oxalates or oxalate hydrates. Alternatively, oxalic acid can be mixed with mine tailings, well drilling dirt, crushed rocks, etc., that contain desired non-carbonate rock minerals, to promote mineralization.

Abstract: A mobile robot system and method for determining the stiffness of a human arm while moving with a user during overground interaction as the user holds the robot's handle and exchanges forces with it. A mobile base moves with the user, a robot arm interacts with the user, and a controller determines the stiffness. The robot arm includes servomotors driving a linkage mechanism, an end effector including the handle supported by the linkage mechanism, and a force transducer measuring a force applied by the user to the handle. The controller causes the robot arm to generate a force perturbation at the handle, measure a peak velocity achieved by the human arm, determine the stiffness of the human arm as a function of force and displacement, and control operation of the system based on the determined stiffness. A robot body may allow for adjusting the height of the robot arm.
