  • Patent number: 10512381
    Abstract: A system comprising a vacuum cleaner and a base station, wherein the vacuum cleaner has a suction opening for sucking up dirt and/or dust from a floor by a suction air flow, a fan for producing the suction air flow, a dust chamber for holding dirt and/or dust, and an air outlet opening such that air sucked in together with the dirt and/or dust can be discharged again. The base station can be connected to the vacuum cleaner in such a way that the dust chamber can be emptied into the base station by means of an air flow. The air flow used to empty the dust chamber can be produced and blown into the dust chamber by the fan for producing the suction air flow. The base station has a return channel, through which the air flow exiting the dust chamber can be guided back into the vacuum cleaner.

  • Patent number: 10471539
    Abstract: A laser containment device, adapted to be mounted to a laser head, has an outer shell and an inner wall defining a peripheral chamber there in-between. An inner seal and an outer seal, respectively mounted to the outer shell and to the inner wall, are adapted to contact a workpiece. The peripheral chamber, encircling an opening in the laser containment device for letting a laser beam reach a workpiece, may be connected to a differential pressure generator operative to generate a differential pressure therein. A pressure sensor is located within the peripheral chamber to read the differential pressure. In use, the laser head, mounted to a computer-controlled manipulator, emits its laser beam. The pressure sensor sends its pressure readings to a controller which compares their values with a predetermined pressure threshold. If the pressure readings cross this threshold, the controller stops the emission of the laser beam.

  • Patent number: 10420600
    Abstract: An ablation device having an electrode control system configured to adjust an output of an active electrode and a variable aspiration control system configured to control aspiration in an aspiration system based upon the output of the active electrode is disclosed. In particular, the variable aspiration control system may adjust the aspiration within the aspiration system between at least a zero aspiration setting corresponding to a low ablation power setting and a high aspiration setting corresponding to a high ablation power setting, whereby a plasma field developed at the active electrode at the high ablation power setting is greater than a plasma field developed at the active electrode at the low ablation power setting. By reducing, if not, ceasing the aspiration provided by the aspiration system for the low ablation power setting, the variable aspiration control system is able to reduce the likelihood that the plasma field will be disturbed.

  • Patent number: 10413144
    Abstract: A vacuum cleaner attachment generally includes a cleaning element that floats relative to a suction conduit of the vacuum cleaner attachment. The cleaning element is supported on a support structure that is movably coupled to a housing and is biased towards a floor, for example, as a result of the weight of the cleaning element support structure. The cleaning element may be permanently attached to the support structure or may be a removable or disposable pad or sheet attached to the support structure. The floating cleaning element may be supported between the suction conduit and one or more wheels of the vacuum cleaner attachment. The vacuum cleaner attachment may be removably attached to a vacuum cleaner, for example, to be used interchangeably with other surface cleaning heads.

  • Patent number: 10299654
    Abstract: A fluid suction device includes an elongate handle having a suction head at its distal end. The suction head extends in opposing directions substantially perpendicularly to the handle. The suction head includes an elongate longitudinal aperture in its outer wall in fluid communication with a suction pump. An absorbent panel covers the longitudinal aperture. When the suction head is applied to a spilled fluid, the wicking action of the absorbent panel and the negative air pressure from the suction pump allows rapid and efficient cleaning of an area affected by a fluid spill. The device also allows for safe and efficient removal of potentially dangerous objects such as broken glass. The device collects fluid in a waste reservoir so that it is easily disposed of.
