A micromachined ultrasonic transducer array comprising a multiplicity of cMUT cells built on a substrate. Each cMUT cell comprises a compliant support structure built on the substrate, a membrane supported over a cavity by the compliant support structure, a first electrode supported by the membrane, and a second electrode that forms a capacitor with the first electrode, the cavity being disposed between the first and second electrodes. The compliant support structure uncouples the non-membrane outer surface of each cMUT cell from the supporting substrate.

An eccentric mass (EM) motor in a vibrotactile transducer provides a wide band vibrational stimulus to a mechanical load in response to an electrical input. The eccentric mass and motor may form part of the transducer actuator moving mass, which is in contact with a load, i.e, the skin of a user. The moving mass and the actuator housing may be in simultaneous contact with the load. The moving mass may be guided by a spring between the actuator housing and the moving mass. The load, moving mass, spring compliance, and housing mass make up a moving mass resonant system. The spring compliance and system component masses may be configured to maximize the actuator displacement and/or tailor the transducer response to a desired level. This configuration may be implemented as a low-mass wearable wide-band vibrotactile transducer.

An aerator for mechanically inducing near laminar flow and controlled turbulence in a liquid waste treatment lagoon or pond. A blower, blower mount platform, diffuser modules, aeration manifold, aeration chamber, an adjustable, telescoping aeration chamber extension, baffles, and buoyancy apparatuses attach to a frame. The diffusers are located beneath the surface of the body of liquid at a predetermined, fixed depth. The blower supplies air to the diffusers and liquid-bubble mixture is released into an aeration chamber where artificial aeration is maximized. The mixture then rises through the aeration chamber. Bubble dissipation and flow conditioning baffles force bubbles to coalesce and vertically dissipate into the atmosphere. The liquid flows over the top of the baffles and a flow manipulation rim to radiate outward and parallel to the pond surface with minimum turbulence at an optimum flow discharge rate. The aerator provides optimized oxygen transfer at low energy costs.
