Abstract: A method for storing a file containing personal data comprises obtaining a temporary anonymous identifier (AnonID.m) of a person, which temporary anonymous identifier (AnonID.m) is dependent on a token (FileID.m) of the file; extracting personal data items from the file associated with the person; for each personal data item, generating a locator (Loc.m.n), which allows the personal data item to be reinstated into the file, and an item-specific anonymous identifier (AnonID.m.n) of the person, wherein the item-specific anonymous identifier is generated by applying a predefined one-way function to a combination of the temporary anonymous identifier (AnonID.m) and an identifier (n) of the personal data item; storing each personal data item together with the locator and the item-specific anonymous identifier in a first memory; and storing an anonymized version of the file without the personal data items in a second memory.

Abstract: A method for counting a number of moving objects that cross at least one predefined curve in a scene comprises making detections of positions of one or more moving objects in the scene, tracking the positions of the moving objects over time based on the detections to produce one or more corresponding tracks, wherein each track is described by a time dependent probability density function, calculating, for each moving object, a success probability pi that the moving object succeeded to cross the at least one predefined curve in the scene, wherein the success probability is calculated by using the time dependent probability density function describing the track of the moving object, and calculating an expected value and a variance of a number of moving objects that crossed the at least one predefined curve by summing success probabilities pi and summing products pi(1?pi) of success and corresponding failure probabilities, respectively.

Abstract: An impeller includes first and second impeller portions that are secured to one another. An interior cavity is formed between the first and second portions. The first impeller portion supports multiple blades. The first and second impeller portions respectively include first and second surfaces that are secured to one another near a tip of the impeller. Inlet and outlet apertures are provided in the impeller and are in communication with the inner cavity to provide a cooling flow path there through. A circumferential gap is arranged between the first and second impeller portions opposite the tip to permit relative axial movement between the first and second impeller portions during centrifugal loading of the impeller.
