Numerous mobile devices report their respective locations to a server which collects the location reports to provide real-time pedestrian traffic information, e.g., as a map that shows locations of individual mobile devices. Distribution of mobile devices in a geographic area more closely represents overall population locations and densities. Each device is identified by a digital fingerprint, formed from a number of system and device configuration parameters. Each mobile device is configured to periodically report its location, e.g., at a predetermined time interval and/or whenever the mobile device determines its location for another reason. A known location of a wireless network access point to which a mobile device is connected can serve as an estimated location of the mobile device.

A vehicle spring for a spring system, includes a spring body (20) and is produced, in particular rolled, from a profiled bar (1) made of a flat steel bar, in particular spring steel, in a hot deformation process. The profiled bar (1) or the spring body (20) has at least one material recess (6) which is provided over the length of the profiled bar or the spring body at least in some regions. The cross-sectional shape of the profiled bar (1) can be the same over the entire length of the profiled bar, whereas the cross-sectional shape in the spring body (20) can vary over the length of the spring body.

A flexible sleeve dimensioned for securement to an associated end member for an associated gas spring assembly includes a flexible wall. An annular reinforcement member is embedded within the flexible wall. A retainment element that includes an element surface is disposed along the flexible wall such that at least the element surface is outwardly exposed. At least one gas spring piston, at least one gas spring assembly and at least one method are also included.

A device for the elastic mounting of an engine, in particular an engine transmission unit, on a motor vehicle body, comprising a rigid support with a supporting section and a mounting section, to which the engine can be fastened, a rigid flange ring which can be fastened to the motor vehicle body and surrounds the full circumference of the supporting section, and a spring body which is elastically supported on the supporting section of the support and on an inner side of the flange ring.

A gas spring assembly includes an end member, a piston assembly and a flexible sleeve secured therebetween. An end closure secures an end of the flexible sleeve to the piston assembly. A connector fitting connects the end closure to a support post of the piston assembly. The connector fitting includes a fitting passage and a first annular groove. A jounce bumper assembly is supported on the connector fitting. The jounce bumper assembly includes a bumper body and a bumper mount. The bumper mount includes securement pin having a second annular groove. A retaining member is received within the first and second annular grooves such that the jounce bumper assembly can freely rotate relative to the connector fitting while substantially restricting axial displacement of the jounce bumper assembly relative to the piston assembly during such rotation.

A process for forming a high temperature single crystal canted spring is provided. In one embodiment, the process includes fabricating configurations of a rapid prototype spring to fabricate a sacrificial mold pattern to create a ceramic mold and casting a canted coiled spring to form at least one canted coil spring configuration based on the ceramic mold. The high temperature single crystal canted spring is formed from a nickel-based alloy containing rhenium using the at least one coil spring configuration.
