Abstract: A handheld light assembly for eradicating pathogens includes a housing. A processor and a lamp are disposed inside the housing. The lamp irradiates surfaces with disinfecting ultraviolet light having a peak wavelength of 222 nm filtered to restrict illumination to between 200 nm and 230 nm within an irradiation zone. A distance measuring system includes a secondary light source generating secondary light and a photodetector for measuring distance of the secondary light to a surface being irradiated by the lamp light being reflected from the surface to the photodetector. The secondary light source is offset at an angle from the lamp thereby projecting the light beam to a central area of the irradiation zone generated by the lamp. The photodetector signals the processor to calculate a vertical distance between the lamp and the central area of the irradiation zone on the surface being irradiated from an angular projection of the secondary light.

Abstract: Some disclosed embodiments are directed to methods and systems for performing pair-wise delta compression. For example, systems obtain a set of files to be compressed into a single compressed file. The system identifies different attributes related to the set of files. For each file in the set of files, the system predicts an optimized set of candidate compression files and calculates a delta between each file in the optimized set and the target file corresponding to the optimized set. After identifying the smallest delta, the system compresses the selected pair of files associated with the smallest delta in order to generate the single compressed file for the set of files.

Abstract: In response to an initiation of a lane-change, a speed of a host vehicle in a current lane can be adjusted to establish a forward longitudinal distance from a lead vehicle in a target lane. The host vehicle is then moved from a first lateral position to a second lateral position in the current lane based on determining that a rear longitudinal distance of the host vehicle from a trailing vehicle in the target lane is less than a rear distance threshold, and then is additionally moved the host vehicle from the second lateral position to a third lateral position in the current lane based on determining that the rear longitudinal distance is increasing. When the forward longitudinal distance exceeds a forward distance threshold and the rear longitudinal distance exceeds the rear distance threshold, the vehicle is moved from the current lane to the target lane.

Abstract: A method for use in a material decomposition procedure applied to dual-energy CT projection data. Material decomposition is often done using pre-computed lookup tables (LUTs) for mapping input projection data, acquired with particular X-ray source parameters, to material data values. However, the X-ray source parameters can vary over the course of a scan, making the results inaccurate. Embodiments are based on determining in advance a plurality of sets of basis LUTs for each of a plurality of different possible ranges of values over which the X-ray source parameter may vary during a scan. The basis LUTs in each set are devised as being LUTs which represent the majority contribution to the overall material decomposition function for the time-varying energy spectrum.

Projection data of an object are acquired, wherein the projection data comprises a first subset of data to be used for reconstruction of a first image, and a second subset of data comprising projection data not to be used for the construction of the first image, wherein the second subset of data comprises projection data not comprised in the first subset of data. A first and a second image are reconstructed using the first and the second subset of data, respectively. A second pass artefact reduction method is performed using the second image as input image of the second pass artefact reduction method, thereby reducing artefacts in the first image.
