Abstract:
The present disclosure provides an inspection system and method for inspecting an optical surface of a laser scanner, the system including a directional optical source and an optical detector. The method includes moving one of the laser scanner or the inspection system to a position in which a beam axis of the directional optical source extends across but does not intersect the optical surface, between the optical surface of and the optical detector. The method further includes emitting a light beam from the directional optical source, across the optical surface so that light from the light beam is incident on debris disposed on the optical surface. The method further includes collecting the light at the optical detector to form an image that indicates presence of the debris on the optical surface of the laser scanner; and generating feedback to alert a user of the presence of the debris.
Abstract:
A water quality sensor includes a housing including a light transmissive bucket mounted in an electrical washing appliance and a light transmissive inner barrel mounted in the bucket, an actuation module mounted in the inner barrel for detecting a water quality of a washing solution in the electrical washing appliance. Thus, if the bucket is cracked during manufacturing or due to a collision, the contact actuation module can still be well protected by the inner barrel, so that the washing solution in the electrical washing machine does not directly flow into contact with the actuation module to cause an accidental short circuit of the circuit substrate of the actuation module, improving the water resistance and service life of the water quality sensor.

Abstract:
Microplate reader has a housing, at least one optical measuring/detection device, a microplate support, a moving unit and an integrated lid holding apparatus. The lid holding apparatus moves the microplate in one respective, at least approximately vertical direction for moving the microplate lid away from the microplate. The lid holding apparatus is arranged inside the housing as a magnetic lifter and comprises a non-array arrangement of at least one permanent magnet, or at least three electro magnets, or at least one switchable permanent magnet. Each microplate lid to be moved away from the microplate comprises magnetizable material with a physical area. A projected area of the at least one permanent magnet, electro magnet, or switchable permanent magnet is smaller than the physical area of the magnetizable material of the microplate lid.
Abstract:
A gas cell assembly and applications of the gas cell assembly in absorption spectroscopy. An example gas cell assembly includes a gas cell body with an inlet for receiving a gas sample from a gas source; a first and a second end portions that allow optical transmission into and out of the body, the second end portion being substantially opposite from the first end portion; and a channel providing a path for the gas sample and optical beam(s) between the first end portion and the second end portion. The gas cell assembly also includes reflective surfaces outside the body to receive versions of the optical beams from the body and to reflect each version of the incident beam towards the body. A detector, then, receives a last reflected beam and transmits a corresponding data signal to a processing unit for analyzing the gas sample based on the data signal.
Abstract:
A system for collecting gas samples emitted from skin and detecting concentrations of specified components therein. The system includes a collection chamber housing defining an interior space, the collection chamber housing having a gas inlet, a gas outlet, and an opening. The opening is configured for enclosing a skin portion from which to receive an emitted gas sample and sealing the interior space against the skin portion. An inert gas source is connected to the gas inlet, which is capable of allowing inert gas from the inert gas source to flow into the interior space. A gas cell is connected to the gas outlet, which is capable of allowing the inert gas and the gas sample to flow from the interior space into the gas cell. As a laser travels through the gas cell, power and optoacoustic signals are measured and used to determine a concentration of the specified component.
Abstract:
Various systems and methods of analyzing one or more properties of a sample are provided. The system includes a self-contained purging device having a sample holder and one or more analyzers for analyzing one or more properties of the sample. The purging device is configured to remove sample contained within the sample holder when an analysis is complete. In one embodiment the purging device is configured via an air pump having a tube in fluid communication with an air inlet of the sample holder, wherein the air pump is configured to deliver pressurized air to the air inlet and thereby purge the sample. The pressurized air is localized ambient air, and substantially free of contaminants. Methods and other systems are also described and illustrated.
