摘要： A device and method for efficient computation of statistical information, such as a mean, co-variance, or histogram of the image pixels, over discrete image regions. The computation employs integral computations to determine the statistical information over image regions of arbitrary shape, including irregular polygonal shaped regions. The integral computations are simplified by categorizing corner points of boundaries of image regions. The computation can be applied to calculate descriptors or signatures of persons or objects within an image. The computation also has a low computational cost enabling fast calculation of image statistics.

摘要： A system for detecting and counting individuals in a stationary or moving crowd based on a digital or digitized image captured from a single camera. Initial information is assumed based on a foot-to-head plane homology, where a geometric construct is developed to best enclose image features with a high probability of being an individual within a crowd. These geometric constructs are then subjected to further probabilistic analysis to determine individuals. The vector track of each individual is determined to validate the determination of a group of features as individuals, thereby compensating for occlusion of an individual within any given frame image. A virtual gate is then employed to count the individuals moving past the virtual gate. Also, by weighting portions of the individual, events near the gate can be predicted.

摘要： A valve for metering a flowing, e.g. gaseous or liquid, medium, in particular a fuel injection valve for internal combustion engines, is described, which valve comprises a valve housing having an inflow for the medium, a valve body having a metering opening for the medium, a join present between the valve housing and valve body, and a seal sealing the join. In order to ensure a seal that is reliable and not susceptible to cracking, in which context the material of the valve housing and valve body can be selected without restriction, the seal has a clamping ring, covering the join, that sits with a press fit on end portions, facing toward one another at the join, of the valve housing and valve body.

摘要： A system and method for vehicle-centric infrastructure monitoring system includes an inspection system mountable on a vehicle configured to travel over an expanse of rail track having a plurality of track blocks. The inspection system acquires track data for at least some track blocks along the expanse of rail track. The monitoring system also includes a positioning system to determine a location of the vehicle and generate location data indicative of an associated track block location, a communications device to transmit the track/location data to a remote location, and a centralized computing system positioned at the remote location to receive the transmitted track/location data. The centralized computing system is programmed to determine a current probability of a track condition for a track block and combine the current track condition probability with a previously determined cumulative track condition probability to provide an updated track condition probability for the track block.

摘要： A fuel injection valve for fuel injection systems of internal combustion engines includes a core which serves as the internal pole is made of a soft magnetic powder composite material. This powder composite material is an iron powder provided with a polymer additive, where the individual iron particles are coated with an electrically insulating layer. Such a powder composite material ensures a substantial minimization of eddy currents in the magnetic circuit in comparison with materials known previously, such as chromium steel, which are usually used as magnetic materials. The core which is mechanically sensitive and is sensitive to fuel is encapsulated at least with respect to the parts of the injection valve carrying the fuel. A sleeve passes through an internal longitudinal opening in the core which permits fuel flow in its interior and is fixedly attached to a pole part which seals the core toward the bottom. The core and the magnetic coil are thus not exposed to any wetting by fuel. This fuel injection valve is especially suitable for use in fuel injection systems of internal combustion engines with mixture compression and external ignition.

摘要： A valve for metering a fluid (liquid or gaseous medium), in particular, a fuel injector for internal combustion engines, having a valve housing, an actuator accommodated in the valve housing and acting on a valve member, an electrical connector accessible on the outside of the valve housing, and an electrical supply lead that produces an electrical connection from the connector to the actuator and has two lead strands, each having a flexible strand section. To optimize the electrical supply lead to lower production costs, simplified valve assembly and anti-twist protection for the actuator, each lead strand is made of an electrical conductor provided with a plastic sheathing and having a front and rear, in each case elongated conductor section and a middle conductor section in between that has at least one meander-shaped curvature for realizing the flexible strand section, and a plastic bridge member, in one piece with the plastic sheathings in the area of the middle conductor sections of both electrical conductors, connects the two lead strands to form a torsionally stiff supply-lead module.
