Abstract:
The invention relates to an illumination-induced multispectral imaging system comprising a digital handheld camera; an illumination device integrated to or mountable on the digital handheld camera, the illumination device comprising a plurality of LEDs wherein each LED is configured to emit light within a single spectral band, said single spectral band being characterized by a central wavelength comprised between 400 nm and 1500 nm, wherein said plurality of LEDs is arranged to emit light in at least two different non-overlapping spectral bands; the imaging system further comprising a control unit configured to sequentially activate the LEDs such that only one spectral band is emitted at a time, wherein the control unit is further adapted to sequentially activate the LEDs during a sequence of image acquisitions by the digital handheld camera, wherein the acquisition of each image is synchronized with the sequential activation of the LEDs, such that each image is acquired during an emission period of only one spectral band. The invention further relates to a method for the acquisition of a multispectral image using an illumination-induced multispectral imaging system and to a multispectral illumination device.

Abstract:
In one scenario, a computer system wirelessly receives an image from a mobile device. The computer system identifies an available paint color closest to the color of the received image, and further identifies available paint colors that color coordinate with the paint color determined to correspond to the image. The computer system then displays to the user the paint color determined to correspond to the received image and the color coordinated paint colors, receives user input selecting the displayed colors, determines a tint formula corresponding to the selected color and produces a paint code corresponding to the selected color based on the tint formula.
Abstract:
According to an example embodiment, a detector assembly (210) for use in analysis of elemental composition of a sample (229) by using optical emission spectroscopy is provided, the detector assembly (210) comprising a rotatable element (222) that is rotatable about an axis (A) and that has attached thereto a laser source (221) for generating laser pulses for invoking optical emission on a surface of the sample (229), the laser source (221) arranged to generate laser pulses focused at a predefined distance (r) from said axis (A) at a predefined distance (L) from a front end of the detector assembly (210), and a detector element (227) for capturing optical emission invoked by said laser pulses.
Abstract:
A disposable measurement tip for an instrument for measuring at least one parameter of a sample, the measurement tip comprising; a tip body; a filling channel in the tip body for holding the sample to be analyzed and having an opening on one end of the tip body to receive the sample; a population of micro-particles held within the tip body filling channel and which can be mixed with the sample when the sample is received in the filling channel; wherein in use the sample in the tip is illuminated by the instrument and the illumination which impinges on the micro-particles is directed back, by the micro-particles, to the instrument to be detected and to thereby enable the at least one parameter to be determined.
Abstract:
There is provided a laser event recorder (100) comprising an image sensor, a processing unit coupled to the image sensor, and a wireless transceiver coupled to the processing unit. The processing unit is configured to identify when the image sensor is illuminated by a laser (16); in response to the identification, record a laser event comprising at least one characteristic feature of the laser (16); and send the recorded laser event to a central server (300) using the wireless transceiver. There is further provided an application software for configuring a smartphone as the laser event recorder, and a laser event recording system comprising the laser event recorder and the central server.
Abstract:
Portable analytical equipment, systems, methods, and techniques related thereto is disclosed. Portable analytical equipment can comprise a controller and a probe. The probe can interrogate a sample and receive a response to the interrogation. The controller can select and/or initiate an analysis related to interrogating the sample via the probe. The analysis can be selected from a portfolio of analyses stored on the controller. The controller can analyze the response to the interrogation based on reference data stored on the controller. The controller can determine an indication based on the analyzing the response for presentation via a low-power interface, which can comprise an LED or electrophoretic element. The controller can further be connected to an external device, e.g., a smartphone or remote PC, to present collected data and the analyzing of the response to the interrogation. The disclosed subject matter can be employed in hand-held analytical equipment, e.g., a hand-held Raman spectrometer.
