A laser projection system including a system controller, a visible light source, and a light disrupting element is provided. The SEN includes a connection end adapted to attach to a slide gate mechanism, a discharge end including a bifurcated port, a tapered bore extending between the connection end and the discharge end, and a flow control structure positioned within the discharge end. The gated RF receiver is configured and arranged to receive RF energy reflected by objects within the sensor field. Also described are speed up techniques for reaching target data levels more quickly, using more aggressive memory programming operations.
