Latest Patents

Yearsley's latest patents include the "Collinear Terminated Transmission Line Structure" and the "Active Trim Method and Apparatus." The collinear terminated transmission line structure presents a method for producing a structure that comprises a plurality of conductors electrically connected to resistors. The predetermined spacing between the conductors ranges from 2 mils to 7 mils, allowing for greater spacings with the current method. The process involves screen-printing a resistor swath onto a substrate, followed by dipping the substrate into a solution and laser trimming the resistor swath.

The active trim method and apparatus features an electronic probe circuit with AC and DC amplifiers. This circuit is enclosed within a trim housing that replicates the electrical effect of the probe housing. The calibration factors are determined by measuring voltage differences at specific time intervals, and the circuit components are laser trimmed to achieve precise values.
