Abstract: Eyewear including a sensor integrated into frame of eyewear. In one example, the sensor comprises a strain gauge, such as a metallic foil gauge, that is configured to sense and measure distortion of the frame when worn by a user and under different force profiles, by measuring a strain in the frame when bent. The measured strain by strain gauge is sensed by a processor, and the processor performs dynamic calibration of image processing based on the measured strain. The distortion measured by the strain gauge is used by the processor to correct calibration of the cameras, and the displays.

Abstract: A ladder includes a first rail. The ladder includes a second rail. The ladder includes a step attached to the first rail and the second rail. The ladder includes a first brace attached to the first rail. The ladder includes a second brace attached to the second rail. Each brace is attached at least at two distinct points to the step and at least at two distinct points to a respective rail. A brace for supporting a step to first and second rails of a ladder includes a central portion. The brace includes a rail portion extending from the central portion which attaches to a respective rail. The brace includes a step portion extending from the central portion which attaches to the step. A method for using a ladder. The method includes the steps of placing a load on a step. There is the step of distributing the load to the rails from the step through a first and second brace attached to the first and second rails, respectively.
