A method of reading a coupon channel that displays a test section pattern after being exposed to a target substance, the method uses a device having a computer readable memory, digital camera, logic assembly and user interface; providing a pixel target intensity profile; placing the coupon in the device and exposing the coupon channel to a test fluid mixture; automatically using the digital camera to take a digital image of the coupon channel test section after the exposure. The improvement in the method includes finding the contiguous set of pixels from the test section of the coupon channel that best matches the intensity profile of the target pattern representation and determining if this best match set of pixels exceeds a similarity threshold and in response to a best match set of pixels passing the similarity threshold, automatically providing a human perceptible indication that the target substance has been detected.

A device for photometric qualification of lateral flow quick tests by means of camera imaging includes an arrangement which manages with a pinhole aperture with a slot-shaped opening, which has been integrated into the basic housing body, in which the imaging has been optimized with a view to diffraction, imaging scale and integration behavior and in which the illumination and all the components are arranged in a housing which can be produced at a reasonable price, with the result that the quantifiability of customary LFA quick tests is made possible for the user with a sufficient precision. The device can transmit test-specific data automatically and contact-free with the help of electromagnetic waves via a transponder (RFID) and is thus suited for various tests and for quantification of LFA's. The device may work autonomously with an internal microcontroller (embedded system). The figures can be stored and optionally transmitted to a computer via an interface.

An active-source-pixel, integrated device capable of performing biomolecule detection and/or analysis, such as single-molecule nucleic acid sequencing, is described. An active pixel of the integrated device includes a sample well into which a sample to be analyzed may diffuse, an excitation source for providing excitation energy to the sample well, and a sensor configured to detect emission from the sample. The sensor may comprise two or more segments that produce a set of signals that are analyzed to differentiate between and identify tags that are attached to, or associated with, the sample. Tag differentiation may be spectral and/or temporal based. Identification of the tags may be used to detect, analyze, and/or sequence the biomolecule.

Apparatus and methods for analyzing single molecule and performing nucleic acid sequencing. An integrated device includes multiple pixels with sample wells configured to receive a sample, which, when excited, emits radiation; at least one element for directing the emission radiation in a particular direction; and a light path along which the emission radiation travels from the sample well toward a sensor.

The instrument includes an excitation light source for exciting the sample in each sample well.

A repair welding inspection device includes a memory that stores instructions and a processor that executes the instructions. The instructions cause the processor to perform acquiring a second threshold, which is different from a first threshold which is a determination threshold for inspection of welding performed before performing repair welding, and the second threshold being a determination threshold for inspection of the repair welding, and performing inspection after the repair welding by using the second threshold.
