Embodiments of the disclosure provide structures for sensing, activation, and signal networking in a composite textile. According to one embodiment, a composite textile can comprise an activation layer of a reactive yarn knit into a fabric. The reactive yarn can have at least one physical property that changes in response to a stimulus. A signaling layer of a first conductive yarn can be knit into the fabric with the activation layer. The first conductive yarn provides the stimulus to the reactive yarn. A sensing layer comprising second conductive yarn can be knit into the fabric with the activation layer and signaling layer. The second conductive yarn can provide a feedback signal corresponding to the stimulus provided by the first conductive yarn of the signaling layer.

Composite textile structure for sensing, activation, and signal network

A measurement system measures various PCB panel characteristics, such as PCB panel thickness, surface feature thickness (height), surface feature width and length, and warpage. Various techniques are also described for steadying the PCB panel for measurement, whether the PCB panel is positioned horizontally or vertically. Z-height measurements as well as light intensity measurements can be used to determine the various PCB panel characteristics. Either the determined light intensity values, the determined Z-height values, or both can be used to determine pixel transition from one region, or material type, to another. Techniques are also provided to reduce PCB panel vibration and/or automatically adjusting a Z-height of the sensor to ensure a sampling point on the PCB panel is within an allowable Z-height range.
