A lens structure system with a lens structure and a multi-segmented transducer coupled to the lens structure. Each segment in the plurality of segments has a first conductor and a second conductor, wherein the first conductor and the second conductor are electrically coupled to the segment. The system also has circuitry for applying a voltage to selected segments in the plurality of segments with standing wave signals and traveling wave signals.

A self-vibrating pH probe comprise a housing containing an electronic assembly to which is coupled a vibration source element so that at least a portion of vibrations caused by the vibration source element propagate to the electronic assembly, the vibration source element being controllable for at least on/off operation. The self-vibrating pH probe further comprising a pH probe member having a probe tip at a first end, the probe member extending from the housing and mechanically and electrically coupled by a second end to the electronic assembly so that at least a portion of vibrations propagating to the electronic assembly further propagate to the probe tip; and further including a processor coupled to the electronic assembly for coordinating operation of the vibration source element and operation of the pH probe member.

The present invention relates to a recycling process for a laminate and a solution used in such a process. The present invention finds particular application in the removal of an adhered overlay from an underlying substrate material such as plastic. The process includes subjecting the laminate to an impact frictional striking force, thereby substantially separating the substrate layer from the one or more surface layers of the overlay and then washing the substrate layer with a washing solution to remove the remaining surface layers of the overlay and glue from the substrate layer. The washing solution may be an aqueous solution including a surfactant, a solvent and a base.

A system for use on a planetary surface includes ridges arranged parallel to each other. The ridges support a weight of an extraterrestrial vehicle rolling over the ridges. The system also includes a base to maintain a relative position of the ridges to each other and a controller to control one or more of the ridges to vibrate.

The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

In a method for operating a system, a first vibration is imparted to a component of the system and the first vibration of the component is detected by a sensor. The sensor generates a sensor signal for transmission to a control device, which analyzes the sensor signal and determines whether a buildup is present on the component based upon the analysis of the sensor signal. A second vibration is imparted to the component to remove the buildup when the buildup has been detected.
