Abstract: A method for eliminating misjudgment of a reflective light applied to an autonomous robot is provided. The autonomous robot includes a driving system and an optical sensing system that includes a light source and a light sensor. The light source emits a transverse linear light as detection light and the light sensor senses reflective light signals from an object that reflects the detection light. In the method, a frame image including the reflective light signals is captured by the light sensor, characteristics of the reflective light signals are analyzed, and the characteristics of the reflective light signals can be corrected based on the characteristics of previous reflective light signals stored in a memory of the autonomous robot in order to exclude abnormal information. The object can be confirmed based on the corrected characteristics of reflective light signals. The misjudgment caused by the abnormal information can therefore be eliminated.

Abstract: A process for calibrating a distance and range measurement device coupled to an industrial vehicle comprises taking a first measurement of an emission from the device at a first yaw angle relative to a roll axis of the device. A second measurement of the emission at a second yaw angle relative to the roll axis is taken. The second yaw angle is within an angular tolerance of the first yaw angle but in an opposite direction. The device is calibrated relative to the roll axis when the first and second measurements are within a tolerance of each other. A third measurement of the distance and range measurement device beam emitted from the distance and range measurement device at a pitch angle is taken. If the third measurement and a virtual emission length are within a tolerance, then the device is calibrated with respect to the pitch axis.

Abstract: Disclosed are methods that, by not physically touching a material being measured, can measure the material's differential response quite accurately. A collimated light shines on the material under test, is reflected off it, and is then captured by a device that records the position where the reflected light is captured. This process is done both before and after the material is processed in some way (e.g., by applying a coat of paint). The change in position where the reflected light is captured is used in calculating the deflection of the material as induced by the process. This measured induced deflection is then used to accurately determinate the stress introduced into the material by the process. Other characteristics of the material under test, such as aspects of the material composition of a bi-metallic strip, for example, may also be determined from a deflection measurement.
