摘要： The method and system uses ultrasound (US) transducers in contact with an inboard surface underwater portions of marine vessels or structures. By first digitally generating disruptive, multi-frequency, interfering US waveform signals (complex waveforms, typically replicating a Bessel function) and then converting the signals into analog, the transducers generate disruptive, multi-frequency, interfering US waveforms through the underwater portions of the marine vessels and structures which waveforms disrupt unwanted marine growth on the water-side of the vessel or structure. The digital signals, and also the analog signals, are complex waveform signals, typically produced with a Bessel function. The US transducers are either circular membrane transducers or surface transducers. A computer processor coupled to a memory, generates the complex waveform signals fed to the US transducers.

摘要： A vibrating device includes a dome-shaped cover, a cylindrical or substantially cylindrical vibrating body, and a piezoelectric element. The dome-shaped cover is disposed so as to include a detection field of an optical detector element, and the cylindrical or substantially cylindrical vibrating body is fixed to the cover. The piezoelectric element is fixed to the vibrating body and vibrates the cover via the vibrating body. The vibrating body includes a cylinder portion, a first connection portion connected to a first end portion of the cylinder portion, a first ring-shaped portion connected to the first connection portion at a position near the cover, a second connection portion connected to a second end portion of the cylinder portion, and a second ring-shaped portion connected to the second connection portion at a position opposite to a surface to which the cylinder portion is connected.

摘要： A terminal device and a method for removing dust in a sound outlet hole of a loudspeaker are provided. The method includes the following: measuring a natural frequency of the loudspeaker, generating an audio file for removing dust according to the natural frequency, and prestoring the audio file for removing dust, wherein a vibration amplitude of a vibration diaphragm of the loudspeaker is at a maximum when the vibration diaphragm is driven to vibrates by an exciting current having the natural frequency; reading the prestored audio file for removing dust; and controlling the loudspeaker to play the audio file for removing dust, to generate air flow in the sound outlet hole, wherein when the loudspeaker plays the audio file for removing dust, a wind speed of the air flow through the sound outlet hole is at a maximum.

摘要： The present disclosure relates to an apparatus for removing industrial powder from a shaped body manufactured generatively using the industrial powder. The apparatus includes at least one container for holding the shaped body having a vertically adjustable construction platform, a vibrating screen, a tilting device for tilting the container, and at least one catching unit adjoining a transfer end of the vibrating screen for catching the shaped body. In one form, the vibrating screen, tilting device, and catching unit are arranged within a housing. In another form, the vibrating screen and catching unit are arranged within the housing and the tilting device is at least partially arranged in the housing. At least one opening in the housing is closed in an airtight manner by a glove such that a user can use the glove to grasp the shaped body caught by the catching unit.

摘要： According to some aspects, a de-powdering subsystem for an additive fabrication system is described. The de-powdering subsystem may comprise a bath subsystem. The bath subsystem may comprise a reservoir configured to contain a liquid and to accept objects to be de-powdered into the liquid, and an agitation facility configured to cause currents within the liquid. The agitator facility may be at least one of (i) a pump configured to circulate the liquid within the reservoir, (ii) a heating element configured to generate convection currents in the liquid, and (iii) a stirrer driven through a linkage to a motor. The bath subsystem may comprise at least one ultrasonic transducer configured to apply ultrasonic vibrations to the liquid within the reservoir.

摘要： The application relates to a cleaning system configured for cleaning of cavities filled with a liquid, including fragmentation, debridement, material removal, irrigation, disinfection, and decontamination. The cleaning system includes an electromagnetic radiation system and a liquid. A treatment handpiece irradiates the liquid within a cavity with a radiation beam, producing a first vapor bubble using first pulse, and, at a different location, a second vapor bubble using a second pulse. The pulse repetition time is adjusted to ensure efficacy, for example such that an onset time of the second vapor bubble is within the first contraction phase of the first vapor bubble, when the first vapor bubble has contracted from its maximal volume to a size in a range from about 0.7 to about 0.1 of the maximal volume.
