Abstract: A system, device and method for deployment of one or more dust accumulation sensors receives a baseline measurement associated with no accumulation of dust in a target environment, receives a time-elapsed measurement associated with positive accumulation of dust in the target environment, determines a quantity of accumulated dust in the target environment based on the baseline measurement and the time-elapsed measurement, generates a spatial dust deposition distribution for the target environment based on the determined quantity of accumulated dust and determines a deployment for one or more dust accumulation sensors for the target environment based on the spatial dust deposition distribution.

Abstract: A continuous dust accumulation monitoring system, device and method monitors and measures dust accumulation via an enclosure and a machine vision subsystem which can include a digital camera. A dirty optics detection subsystem monitors optical clarity and can invoke a cleaning assembly to help maintain clarity of optics for monitoring and measuring dust accumulation.

Abstract: A visual messaging system and device can employ high efficiency LEDs and current driven versus voltage driven circuits to reduce power consumption and enable the device to be powered from IEEE 802.3af (Power over Ethernet (PoE)) standard based power sources. The device can be powered from a local area network (LAN) connection using PoE, and does not require a separate AC power supply. The present invention also uses a 1× yellow algorithm to create the yellow color with one half the instantaneous current of previous circuits. The device can incorporate multiple message inputs for receiving and displaying messages having different priorities, allowing higher priority messages to override lower priority messages.
