Abstract: System and method are disclosed for providing authentication of a terminal device. One embodiment includes a method implemented by a first terminal device. The method may include receiving first location information and receiving a first predetermined signal. The method may also include transmitting status information and the first location information to a server upon receiving the first predetermined signal to allow the server to compare the first location information with second location information received from a second terminal device and to allow the server to transmit the status information to the second terminal device. The status information may indicate that the first terminal device is authenticated and the first location information may indicate a current location of the first terminal device.

Abstract: A camshaft phaser (1) having a stator (2) and a rotor (16), whereby at least one cover (18) is attached to the stator (2) by means of at least one screw (5) that has a head (8), whereby a spring (14) is joined to the rotor (16) and to the screw (5) so as to transmit force, whereby the spring (14) is in contact with a pin (10) that has a polygonal outside shape and that extends lengthenwise from the head (8) of the screw (5).

Abstract: Embodiments of the present invention are directed to improved designs of railroad spikes and improved methods of manufacturing the same. According to one exemplary embodiment, a method for manufacturing a railroad spike may comprise the steps of: preparing a metal blank having a substantially circular cross-section; subjecting the metal blank to at least one cold heading process and at least one cold extrusion process to form a railroad spike having (a) a circular head with a fillet at its bottom side that is angled to engage a railroad tie plate or rail base and (b) a non-threaded shank with a substantially square cross-section and a chiseled tip; and coating the railroad spike with an anti-corrosion material.
