Abstract:
A method of contactless detection of indications of psychoactive components in a liquid (6) is disclosed and an apparatus therefor, the method comprising the steps of emitting substantially monochromatic light at least at two different wavelengths (La, Lb) and detecting the reflection in a free surface (12) of said liquid (6) by means of a photo detector (5), analysing an output signal from the photo detector (5) to identify output parts caused by light emitted from the first (3a) and second emitter (3b), respectively, and determine whether the liquid (6) contains at least one psychoactive component.
Abstract:
A fluorescence detection system includes a light source for coupling with a mobile device and software, having machine readable instructions loadable into memory of the mobile device and executable by a processor of the mobile device, capable of: activating the light source in coordination with capturing one or more images using a camera of the mobile device; analyzing an image captured with the light source on with an image captured with the light source off, to detect a shift of intensity within a predetermined color range within the images; and identifying and authenticating objects by measuring the intensity shift within the images.
Abstract:
A method or process for intra-operatively providing anatomical guidance in endocrine surgery. In one embodiment, the process includes the steps of illuminating human tissues (407) in the neck area of a human being in operation with a beam of light (211, 454), obtaining fluorescent data from the light scattered (428, 405) from the human tissues, finding fluorescent signatures from the obtained fluorescent data, and identifying tissues that are corresponding to the fluorescent signatures that represent thyroid or parathyroid tissues.
Abstract:
The present disclosure relates to a method and apparatus for testing materials. More particularly, but not exclusively, this invention concerns a method and apparatus for testing materials using infrared spectrometry. The invention also concerns the calibration of an infrared spectrometer for use in testing materials using infrared spectrometry. The invention provides a method of calibrating an infrared spectrometer for testing composites in the aerospace industry, comprising the steps of, selecting a plurality of variables which have the potential to influence the physical characteristics of a composite used in the aerospace industry, selecting a plurality of values for each variable and inputting the variable and values into a design of experiments model, thereby obtaining a sample test matrix.
Abstract:
Hand-held optical thromboelastographic sensor and method of using the same for simultaneous assessment of multiple parameters of blood coagulation at a point-of-care. The sensor includes an optical system registering laser speckle intensity associated with a stationary blood sample and data-processing circuitry programmed to derive the multiple parameters from speckle intensity. The circuitry may be part of a mobile device configured to operate without communication with a central server and/or data storage.
Abstract:
Methods and apparatus for evaluating the quality of an environment or process by measuring light emitted from a bioluminescent sample containing ATP, ADP, or alkaline phosphatase. The apparatus comprises a sample collection and analysis system used to collect a sample, mix reagents, react the sample, and collect it in a measurement chamber. The system includes an instrument having a photon detection assembly for use with the sample testing device and one or more probe assemblies that optically cooperate with the instrument. The instrument includes a dark chamber with a reflective interior surface which may be concave or preferably spherical, and a photon detection sensor such as a multi-pixel photon counter sensor. A substantially transparent portion of the probe assembly, and liquid contained therein, focus bioluminescence toward the photon detection sensor.
Abstract:
Chlorophyll fluorescence may be studied in response to a variety of environmental cues or conditions by growing phototrophic organisms under actinic illumination. Such illumination may be punctuated or disrupted to gain information about the photosynthetic properties or performance of the phototrophic organism. Instruments or devices for carrying out the method are also described.
