Abstract: A dynamic digital filtering system for detecting electrical noise in a discrete I/O circuit. The dynamic digital filtering system has a controller for monitoring the logic signal produced by a logic device monitoring a remote I/O device. The logic device includes a circuit for dynamically adjusting the impedance across a power terminal and a terminal receiving a binary signal from the I/O device. Upon a change of state of the monitored logic signal the controller commands the impedance adjusting circuit to momentarily change its input impedance to determine if the binary signal responsible for the monitored change of state of the logic signal was true or false. If the monitored logic signal does not change state during the momentary change in impedance the binary signal will be verified as “true”. If the monitored logic signal does change state during the momentary change in impedance the binary signal will be considered as “false”.

Abstract: Systems and methods for driving optical sources operating at different wavelengths within a smoke sensor are described herein. Multiple optical sources such as light emitting diodes may be used in a photoelectric smoke sensor to detect particles of different sizes. Photoelectric smoke sensors can operate by pulsing the LEDs and measuring a response in a light sensor. The signal measured at the light sensor changes based on the quantity of particles existing in a smoke chamber. Each optical source may have different operational characteristics and thus require different drive currents to operate. LED driving circuitry according to embodiments discussed herein provide a consistent and reliable drive current to each optical source, while maximizing efficiency of power consumption across a range of possible voltages provided by different power sources.
