Abstract: An electronic ballast and ballast housing having an integral ground for a circuit board positioned within the housing. A ‘snap in’ capture means holds circuit board under flexion so as to press a circuit grounding means in electrical contact with an integral grounding device attached to the ballast housing and providing electrical continuity between the circuit grounding means and the ballast housing. The coupler includes a grounding tab with a fulcrum extension extending from the housing and holding a ground plane surface of the circuit board by means of serrated teeth. An alignment tab disposed on a housing wall receives an alignment slot disposed in the circuit board so as to provide proper alignment of the electrical contacts. The coupler includes an overhead extension that engages a jumper wire in the circuit of the circuit board.

Abstract: A particle detection system to identify and classify particles is programmed to capture digitized images of the particle generated by directing a light source through a fluid that includes the particle. The particle scatters the light and the scattered light is detected using a detector. The detector creates a digital signal corresponding to the particle, which is used by the system to generate Bio-Optical Signature. This Bio-Optical Signature can then be used to classify the event, or particle. Count rate and trends of the classified particles are monitored to detect a change that is representative of the overall health safety of the water or by knowing the levels of bacteria in process water, such as Reverse Osmosis (RO) feed water, reject brine, and product water, the operator may better monitor the life and condition of the RO membrane.
