Abstract: A tomographic imaging method which includes the steps of activating fluorescence in a surface layer of a protein-marked or fluorescent dye-marked biological tissue sample not emitting fluorescence or only emitting specific fluorescence to acquire an activated surface of biological tissue sample; performing fluorescence excitation on the acquired surface biological tissue sample, and imaging the fluorescence to acquire a fluorescence image of the surface layer; cutting off the surface layer; exposing an inactivated new surface layer after cutting the surface layer; repeatedly performing activating, imaging and cutting off steps for the new surface layer to repeat tomographic imaging in such a manner till acquiring a two-dimensional image of each layer of the biological tissue sample; and overlapping the two-dimensional images to acquire a complete three-dimensional image of the biological tissue sample, thus acquiring three-dimensional structure information of the entire sample.

Abstract: A vehicle management system includes an onboard vehicle system and a ground system. The onboard vehicle system includes a compressor exit temperature sensor configured to determine an ECS compressor exit temperature; a data acquisition unit coupled to receive the compressor exit temperature, an altitude of the first vehicle, and an ambient temperature and configured to generate a data report; and a communications system coupled to receive and transmit the data report. The ground system includes a ground data server coupled to receive the data report and determine a fouling condition of an environmental conditioning element of the ECS based on at least the compressor exit temperature, the altitude, and the ambient temperature; and a mobile application module coupled to receive the fouling condition from the ground data server and configured to provide an interface for displaying the fouling condition to a user on a mobile device.

Abstract: A maintenance system is provided for an environmental conditioning element of an environmental control system of a vehicle. The maintenance system includes a data acquisition module configured to determine an ambient temperature, an altitude of the vehicle, and a measured ECS compressor temperature; a fouling module coupled to receive the ambient temperature, the altitude, and the measured ECS compressor temperature from the data acquisition module and configured to generate a fouling condition of the environmental conditioning element based on at least the ambient temperature, the altitude, and the measured ECS compressor temperature; and a reporting module coupled to receive the fouling condition from the fouling module and configured to generate a report for a user that includes the fouling condition.
