A chemical vapor deposition system for coating one or more workpieces is described herein. The deposition system includes a plurality of processing chambers which may be operated independently to increase throughput of the deposition system. Each chamber includes a modular fixture that is configured to maintain the workpieces in a predetermined arrangement which allows for a hollow cathode effect to be maintained in an Interior space of the chamber. The deposition system achieves significantly faster, higher-quality deposition and more complete, conformal coverage.

Systems and methods for coating surfaces

Rapid plasma nitriding is achieved by harnessing the power and increased density of plasma discharges created by hollow cathodes. When opposing surfaces are maintained at the proper voltage, sub atmospheric pressure, and spacing, a phenomenon known as the hollow cathode effect creates additional hot oscillating electrons capable of multiple ionization events thereby increasing the number of ions and electrons per unit volume (plasma density). The present invention describes the harnessing of this phenomenon to rapidly plasma nitride metal surfaces and optionally rapidly deposit functional coatings in a continuous operation for duplex coatings.

Plasma nitriding with PECVD coatings using hollow cathode ion immersion technology

An ultrasonic pool occupant sensing device capable of using ultrasonic pulses to analyze the occupancy level of a swimming pool. An ultrasonic transducer sends and receives ultrasonic pulses. A front end electronics has a driver for controlling the transducer, a pre-amplifier, band-pass filter, and amplifier combination for filtering received signals. The digital processing unit contains a timer unit for generating pulses, an AD converter for digitizing received pulses, a signal processor for determining data about the return pulse, and an I/O unit for transmitting data to the central processing unit. The data may be an estimate of the number of people in the sensor range, or it may be data about the return pulse that can be analyzed by the central processing unit.
