Various examples are provided related to hyperspectral imaging of moving microscopic sample elements. In one example, a method for hyperspectral imaging includes acquiring a series of optical images and corresponding hyperspectral data of a sample; compiling a movie comprising a series of frames each including one of the series of optical images and a slit line indicating a location of a slit for acquisition of the hyperspectral data; identifying a frame comprising an element of the sample located on the slit line; and analyzing the hyperspectral data corresponding to the optical image in the identified frame. Each optical image and its corresponding hyperspectral data are acquired simultaneously and identified by a time stamp or sequence number. The analysis can generate hyperspectral information about the element. In another example, a system for hyperspectral imaging includes a hyperspectral imaging device; an optical imaging device; and a computing device.

Hyperspectral imaging of moving microscopic sample elements

In general, an imaging system to synchronously record a spatial image and a spectral image of a portion of the spatial image is described. In some examples, a beam splitter of the imaging system splits an optical beam, obtained from a viewing device, into a first split beam directed by the imaging system to a spatial camera and a second split beam directed by the imaging system to the entrance slit of an imaging spectrograph that is coupled to a spectral camera. An electronic apparatus synchronously triggers the spatial camera and the spectral camera to synchronously record a spatial image and a spectral image, respectively.

Disclosed are various embodiments for methods and systems for three-dimensional imaging of subject particles in media through use of dark-field microscopy. Some examples, among others, include a method for obtaining a three-dimensional (3D) volume image of a sample, a method for determining a 3D location of at least one subject particle within a sample, a method for determining at least one spatial correlation between a location of at least one subject particle and a location of at least one cell structure within a cell and/or other similar biological or nonbiological structure, a method of displaying a location of at least one subject particle, method for increasing the dynamic range of a 3D image acquired from samples containing weak and strong sources of light, and method for sharpening a 3D image in a vertical direction.

An oil leak scavenger apparatus for collecting oil drippings of automobile vehicles which is mounted externally to engine crankcases, transmission housings, and other oil containing units is provided. The scavenger apparatus comprises: (a) an oil collector; (b) a reservoir in fluid communication with the oil collector; (c) a vacuum source in fluid communication with the reservoir; and (d) a vacuum metering valve positioned intermediate the vacuum source and the reservoir. In one embodiment the reservoir is also in fluid communication with the oil containing unit of the automobile, and a check valve is positioned intermediate the reservoir and the oil containing unit of the automobile thus allowing the collected oil to return to its source when the engine is not running.
