The invention relates to encoded surfaces that are read by a three-dimensional radar imaging system. The reader scans different zones in a pre-determined area of the encoded surface, each of said zones comprising projections or indentations, similar to Braille. The image obtained can be used to estimate the position of the camera relative to the known pattern. The relative movement between the reader and the encoded surface allows other areas of the surface to be scanned and, in this way, the sensor can decode a message etched along the path followed by the imaging sensor.

Disclosed are systems for continuous production of ozone strong water, the systems comprising an injection device that injects an acidification agent into a pressurized feed liquid, a diffuser device that injects ozone into a body of the acidic pressurized feed water, and injection nozzles each controlled by a valve that adjust a flow rate of the ozone strong water discharged from a dissolution column to match a flow rate of the acidic pressurized feed water fed to the dissolution column, thereby maintaining a start-up mode in an upper portion of the dissolution column that favors a high efficiency of ozone mass transfer and a steady-state mode in a lower portion of the dissolution column that favors a high dissolved ozone concentration coexistent in the body of the acidic pressurized liquid, wherein a concentration gradient of dissolved ozone is formed along a height of the body of the acidic pressurized liquid.

An evaporation system including a reservoir, for receiving a liquid mixture to be reduced through evaporation; and a tray, for being received in the reservoir, the tray defining a heating chamber into which the liquid from the reservoir may flow, the heating chamber configured to heat the liquid therein to increase evaporation of the liquid.

Techniques are disclosed for forming group III material-nitride (III-N) microelectromechanical systems (MEMS) structures on a group IV substrate, such as a silicon, silicon germanium, or germanium substrate. In some cases, the techniques include forming a III-N layer on the substrate and optionally on shallow trench isolation (STI) material, and then releasing the III-N layer by etching to form a free portion of the III-N layer suspended over the substrate. The techniques may include, for example, using a wet etch process that selectively etches the substrate and/or STI material, but does not etch the III-N material (or etches the III-N material at a substantially slower rate). Piezoresistive elements can be formed on the III-N layer to, for example, detect vibrations or deflection in the free/suspended portion of the III-N layer. Accordingly, MEMS sensors can be formed using the techniques, such as accelerometers, gyroscopes, and pressure sensors, for example.
