The anode system includes a self-cleaning anode having a titanium body with a catalytic coating thereof. The anode includes at least one piezoelectric transducer for producing ultrasonic vibrations and coupling those vibrations to the catalytic coating on the anode to displace or dislodge any fouling deposits that may have accumulated on the anode during normal its normal operation in cathodically protecting the tank.

This invention relates to the technology of sterilizing medical ultrasonic probes, and discloses a portable ultraviolet sterilization case for ultrasonic probe, which includes a sterilization container for disinfecting and storing the ultrasonic probe, and a fixing clamp set configured to the interior of the sterilization container, wherein pairs of clamps trap the ultrasonic probe stably by an elastic structure. Hence the ultrasonic probe can be placed without colliding with the inner wall of the container.

One of the problems is the reduction in interior areas and surfaces where various types of devices can be mounted. To address this issue more and more of these devices are being integrated with the glazing. Laminated glazing is especially suitable for thin devices. Today, laminated glazing is produced with heating elements, antennas, lighting, touch sensors, RFID, electronic blinds and other types of devices integrated as a permanent part of the glazing. The invention comprises an automotive laminate with a thin integrated electroacoustic transducer integrated in the glazing.

Aspects of the disclosure relate to cleaning rotating sensors having a sensor housing with a sensor input surface. For instance, a first signal indicating that there is a contaminant on the sensor input surface may be received. In response to receiving the first signal, a second signal may be sent in order to cause one or more transducers to generate waves in order to attempt to remove the contaminant from the sensor input surface.

A cleaning method includes controlling an unmanned aerial vehicle (UAV) to fly to a region of a wall body according to a path to be cleaned, determining a distance between the UAV and a wall surface of the region of the wall body based on a cleaning mode, and controlling the UAV to clean the wall surface via the cleaning mode and at the determined distance away from the wall surface.

A modular sonic vibration buffer system includes an adapter assembly that can be attached to a sonic vibration device. The adapter assembly includes a body with apertures and a plate with arms that are received in the apertures of the body to couple the plate to the body. A cleaning tool is secured between the body and the plate to couple the cleaning tool to the adapter assembly. The sonic vibration device is operable to vibrate the cleaning tool via the adapter assembly. The system also includes additional adapter assemblies and cleaning tools with different characteristics that are attachable to the sonic vibration device in a modular nature for different cleaning or buffering applications.

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.

A method for decontaminating a low-temperature article, the method comprising: an applying step including applying a decontamination agent to external surfaces of a low-temperature article and supplying a mist of decontamination agent to a first external surface of said low-temperature article to form a condensed film of the decontamination agent on said first external surface; and a drying step including ultrasonically vibrating vibration boards disposed on a periphery of the low-temperature article to generate sound flows from board surfaces by an ultrasound in a vertical direction, irradiating with ultrasonic waves the low-temperature article with the decontamination agent applied thereto, subjecting said first external surface of the low-temperature article to ultrasonic vibration and acoustic radiation pressure, supplying dry air to the first external surface and drying said first external surface.

A system for removing a coating from an underlying layer can include a wave-based weakening system configured to weaken the coating by decreasing a coupling force between the coating and the substrate, a coating removal mechanism configured to remove the weakened coating from the underlying layer, and a sensor configured to determine a property associated with the coating. A method for removing a coating from an underlying layer can include generating a weakened coating and removing the weakened coating.

A device and method for protecting an optical sensor of a vehicle are disclosed, wherein the sensor is protected from environmental pollutants which may adhere to an optical surface of the sensor if the sensor is exposed to them, and wherein the environmental pollutants are kept away from the sensor by an ultrasonic cleaning of the sensor surface using an ultrasonic field. The ultrasonic field of the ultrasonic cleaning is emitted by a protection device into the air to provide a protection zone around the optical surface of the sensor such that a contact of the optical surface with the environmental pollutants is avoided, wherein the environmental pollutants are moved and/or destroyed in the air away from the sensor if they enter the protection zone), and wherein the protection zone provides a contactless cleaning of the sensor.
