Abstract
Systems and methods for sensing capacitances that are applicable to proximity sensor devices are provided. The systems and methods provide decreased implementation costs by reducing the number of output terminals required. Specifically, the systems and methods for sensing capacitances provide the ability to selectively activate indicating transducers, such as LEDs, with the same output terminals used for sensing capacitances. This reduces the need for additional, dedicated output terminals for activating the indicating transducers. As such, the system and method provides for efficient use of resources in proximity sensor devices.
