摘要： A bi-directional comparator compares two input signals and applies a hysteresis level to the smaller input signal only after the output signal switches logical states and when the two input signals are within a predetermined range of each other. In one embodiment, the hysteresis applied to the smaller input signal is removed when the two input signals are no longer within the predetermined range of each other.

摘要： Automated optical inspection of a wearable device and/or sub-assemblies of the wearable device in-situ in an ambient environment where temperature and ambient lighting are need not be controlled are described. A key gold unit for the wearable device or a subassembly of the wearable device may be mounted to an automated optical inspections system that captures images of the key gold unit, converts the image from a color space it was captured in to a Hue, Saturation and Value/Brightness color space. Units under test are imaged while stationary or while being rotated (e.g., 360 degrees) and are imaged. Image data is converted into the Hue, Saturation and Value/Brightness color space and compared with the data from the key gold unit to determine if the unit under test is color matched with the key gold unit. Functionality such as near field communications, capacitive touch, display functionality and others may be tested.
