Macropads can be as simple as a few buttons hooked up to a microcontroller to do the USB HID dance and talk to a PC. However, ...
Abstract: This work presents a 4x2 optical encoder based on a two-dimensional photonic crystal (2D PhC) structure for fast optical communication. The proposed 4×2 encoder design comprises four inputs ...
Abstract: Incremental optical encoders are widely used as photoelectric sensing components in direct current motor servo systems, but their inherent susceptibility to optical interference ultimately ...
