The present invention is directed to a device consisting of a portable and multi-band UV light device that uses a combination of UVA, UVB, and UVC wavelength band of UV emitters. For detection, UV emitters are energized to a particulate collector that will fluoresce and glow when there is the presence of a wide range of different harmful aerosol droplet particles in the air that may be collected. This instant and positive visual detection with an available audio alarm alert indicates the presence of harmful aerosol droplet particles in the vicinity of this Instant Particulate Detector or IPD device, allowing the user to take immediate and corrective action. The user can also subsequently select disinfection utilizing UVC wavelength light to sterilize the particulate collector and Instant Particulate Detector or IPD device.

An apparatus and method are provided for differentiating multiple detectable signals by excitation wavelength. The apparatus can include a light source that can emit respective excitation light wavelengths or wavelength ranges towards a sample in a sample retaining region, for example, in a well. The sample can contain two or more detectable markers, for example, fluorescent dyes, each of which can be capable of generating increased detectable emissions when excited in the presence of a target component. The detectable markers can have excitation wavelength ranges and/or emission wavelength ranges that overlap with the ranges of the other detectable markers. A detector can be arranged for detecting an emission wavelength or wavelength range emitted from a first marker within the overlapping wavelength range of at least one of the other markers.

An inspection system for detecting defects in a workpiece can include an illumination source for illuminating a first section of the workpiece with a patterned light, wherein the illumination source does not illuminate a second section of the workpiece. The inspection system further includes a feedback camera for imaging the first section and producing a first output, and a background camera for imaging the second section and producing a second output. A processor compares the first output with the second output, and a controller alters the patterned light that is output by the illumination source based on the comparison. This feedback control continues until the background is suitably homogeneous or camouflaged compared to the defect, such that the visibility and/or detectability of the defect is increased.

A method for determining a hair colouring result of a hair dye for dyeing hair involves determining, for each partial area of a hair region of hair to be dyed, a value for a first initial state parameter and for a second initial state parameter in the particular partial area. The first initial state parameter contains information concerning a hair state and the second initial state parameter contains information regarding a hair colour. The first initial state parameter and the second initial state parameter describe an initial colour state of the hair to be dyed in the partial area. The method further involves determining the initial colour state of the hair to be dyed for the hair region and computer-assisted determination, for a particular hair dye, of a forecast hair colouring result for the hair in the hair region, taking into consideration the determined initial colour state of the hair in the hair region.
