In cleaning using a self-propelled cleaning device, firstly the cleaning device moves alongside a wall surface and then a reference direction is set. Next, the cleaning device advances alongside the wall surface at a prescribed distance, makes a right-angle turn, and travels in the reference direction. When the cleaning device reaches the surface of an opposing wall, it moves in a spiraling manner. At that time, the orientation angle of the cleaning device, which is estimated using a gyro sensor, is checked and corrected. If an obstacle is encountered while traveling, the cleaning device travels on a path that avoids the obstacle or travels in a spiral manner in a region in front of the obstacle.

The invention provides generally a method and an apparatus for in situ cleaning of a surface in a semiconductor substrate processing chamber which operates quickly and reduces the downtime for chamber cleaning. The apparatus comprises an ultraviolet (UV) radiation plate moveable between a cleaning position and a storage position and at least one UV radiation source disposed on the UV radiation plate. Preferably, the apparatus includes a reflector disposed adjacent the UV radiation source to focus emitted UV radiation and a rotary actuator pivotally attached to a transport arm to move the UV radiation plate between the cleaning position and the storage position. The method comprises: providing a UV radiation plate having at least one UV radiation source disposed thereon, moving the UV radiation plate into a cleaning position, introducing a cleaning gas into the processing chamber and exposing the surface to UV radiation.

Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube. According to some embodiments, a mechanically-actuated non-inflatable cleaning device for scraping debris (e.g., biofilm) from an interior wall of an endotracheal tube is provided. In one embodiment, the cleaning device comprises an elongated member having a proximal end and a distal end and a mechanically-expandable scaffold positioned along the distal end of the elongated member. In one embodiment, the mechanically-expandable scaffold comprises one or more removal members configured to engage an interior surface of an endotracheal tube when the scaffold is in a radially-expanded position and to remove debris from the interior surface of the endotracheal tube when the device is withdrawn from the endotracheal tube.

A high-speed, three-dimensional, gamma-ray imaging method and system as well as a detector and array of such detectors for use therein are provided which characterize radioactivity distributions in nuclear and radioactive waste and materials facilities by superimposing radiation images on a view of the environment using see-through display screens or shields to provide a stereoscopic view of the radiation. The method and system provide real-time visual feedback about the locations and relative strengths of radioactive sources. The method and system dynamically provide continuous updates to the displayed image illustrating changes, such as source movement. A pair of spaced gamma-ray cameras of a detector subsystem function like “gamma eyes”. A pair of CCD cameras may be coupled to the detector subsystem to obtain information about the physical architecture of the environment. A motion tracking subsystem is used to generate information on the user's position and head orientation to determine what a user “sees”. The invention exploits the human brain's ability to naturally reconstruct a 3D, stereoscopic image from 2D images generated by two “imagers” separated by a known angle(s) without the need for 3D mathematical image reconstruction. The method and system are not only tools for minimizing human exposure to radiation thus assisting in ALARA (As Low As Reasonably Achievable) planning, but also are helpful for identifying contamination in, for example, laboratory or industrial settings. Other optically-invisible radiation such as infrared radiation caused by smoldering fires may also be imaged. Detectors are manufactured or configured in curvilinear geometries (such as hemispheres, spheres, circles, arcs, or other arrangements) to enable sampling of the ionizing radiation field for determination of positional activity (absolute or relative amounts of ionizing radiation) or spectroscopy (energy distributions of photons). More than one detector system may be used to obtain three-dimensional information. The detector systems are specifically suitable for direct visualization of radiation fields.

Batch pasteurizers are disclosed for processing milk, colostrum and other dairy products. The pasteurizers comprise inner drums to contain the processed liquid, an outer drum surrounding same and providing an annular space for retaining a heating fluid (heated by an electrical heater), a helical coil to carry cooling fluid through the heating fluid, a motorized pump or impeller to agitate the treated liquid to optimize heat transfer, and a control system to switch the heater on and off, actuate cooling liquid flow and optionally, at least partially drain the heating fluid to provide a temperature/time profile and close temperature tolerance, all of which produce pasteurized products with adequate levels of immunoglobulins to provide newborn animals with sufficient immune function.

A beverage substance for producing a tea beverage is proposed, wherein the beverage substance is intended to be stored in a portion capsule and to be infused in the portion capsule by means of hot water introduced under pressure into the portion capsule, wherein the beverage substance is substantially particulate and at least in part comprises tea, and wherein the beverage substance has a mean particle size of between 500 micrometres and 1,500 micrometres.

Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube for the purpose of increasing the available space for airflow or to prevent the build up of materials that may constrict airflow or be a potential nidus for infection. In one embodiment, a mechanically-actuated endotracheal tube cleaning device is configured to removably receive a visualization member to provide cleaning of the endotracheal tube under direct visualization.

A method of ecological restoration of water bodies containing excess nutrient includes steps of: (a) taming Daphnia magna to be able to eat blue-green algae as an algae eating plankton with a taming composition fermented from spirulina powder, active yeast, and saccharide, so as to digest blue-green algae in the water bodies, and (b) putting the algae eating plankton in the water body polluted by the blue-green algae, wherein the algae eating plankton eats the blue-green algae, so that an eco-system of the water body containing excess nutrient can be restored. The method according to a preferred embodiment further includes a step of: (c) planting submerged plant in the water, wherein the submerged plant includes submerged forest and submerged turf.
