Provision is made for a method of monitoring an immersion fluid in a microscope having a lens which images a sample located on a sample carrier. In a step a), a camera is positioned which has an image field which is oriented in such a way that it captures the sample carrier and a space between the sample carrier and the lens and adjoining the sample carrier towards the lens, which space is used to receive the immersion fluid. In a step b), the immersion fluid is applied into the space between the sample carrier and the lens. In step c), an image with the immersion fluid being in the space between the sample carrier and the lens is recorded, and in a step d), the position, the area and/or the contour of the immersion fluid on the sample carrier from the image recorded in step d) are/is determined.

A method for visualizing biofilm on a solid surface. The method comprises steps of:

(a) providing a solid surface which has been in contact with an aqueous medium and at least a portion of the solid surface potentially is covered with biofilm,
(b) maintaining the solid surface in a horizontal position and covering the solid surface with an aqueous dispersion of carbon particles,
(c) tilting the solid surface at an angle of at least 5° from horizontal to allow excess aqueous dispersion of carbon particles to flow from the surface,
(d) detecting any biofilm present on the solid surface by determining whether there are areas not covered by aqueous dispersion of carbon particles.

An illuminator comprising more than one set of ultraviolet radiation sources. A first set of ultraviolet radiation sources operate in a wavelength range of approximately 270 nanometers to approximately 290 nanometers. A second set of ultraviolet radiation sources operate in a wavelength range of approximately 380 nanometers to approximately 420 nanometers. The illuminator can also include a set of sensors for acquiring data regarding at least one object to be irradiated by the first and the second set of ultraviolet radiation sources. A control system configured to control and adjust a set of radiation settings for the first and the second set of ultraviolet radiation sources based on the data acquired by the set of sensors.

A contaminant detection system includes a light source configured to emit excitation light on an object to be inspected; a detector configured to detect fluorescence emitted from a contaminant adhering to the object to be inspected; and a processor. The fluorescence is caused by emission of the excitation light from the light source onto the object to be inspected. The processor is configured to perform a determination of a location of the contaminant and a type of the contaminant, based on the fluorescence emitted from the contaminant; and output a result of the determination.

An electronic device and a method for predicting water ingress employ a water damage indicator including a water-dispersible coating layer which includes a water-dispersible, radiation-cured polymer. Electronic components of the device, which may be susceptible to water damage, are disposed within a casing. The water damage indicator may contact the casing of the electronic device and/or the electronic components. When water enters the casing, the water dispersible coating layer is at least partially removed, revealing the surface beneath, thereby providing an indication of potential water damage to the electronic components. The water damage indicator is not readily replaceable after manufacture, making it more difficult for a customer to disguise potential water damage to the device.

Systems and methods are described, and one method includes passing an optical beam through a volume of the gas to a reception surface, applying spectroanalysis to the optical beam received at the reception surface, and determining from the spectroanalysis whether a liquid is carried by the volume of the gas.

A method for determining a cleaning strategy for a soiled textile is provided. The method includes obtaining intensity information representative of a spectral image resulting from soiling of a textile. Further, the method includes determining at least one output variable that is dependent on the composition of the soiling on the basis of the intensity information. Also, the method includes outputting or triggering the output of the at least one output variable. Also provided are corresponding devices for carrying out such a method.

The present invention relates to mobile devices for disinfecting an object. The mobile device includes: one or more light sources for generating a disinfection light; a display; one or more processors coupled to the one or more light sources and display; and a non-transitory computer-readable medium comprising one or more sequences of instructions which, when executed by the one or more processors, causes steps to be performed including: determining a required dosage of the disinfection light; determining an exposure time of the disinfection light that corresponds to the required dosage of the disinfection light; illuminating the disinfection light on the surface; and displaying a disinfection map on the display to report a result of a disinfection process performed by the illumination of the disinfection light.
