Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Cam phaser

Hydraulik-Ring's camshaft adjustment systems offer increased power and torque, reduced fuel consumption, and improved capability to meet emissions requirements. Whether a chain- or belt-driven system, the company's solutions accommodate all types of cylinder heads and any number of cylinders. Hydraulik-Ring also is developing new lightweight designs to meet future requirements for reduced weight and inertia.


Fastening system

The AKH Fas-ner solves problems inherent with other joining methods. Benefits of the system include the ability to join precoated metals as well as dissimilar metals, electrical continuity at the joint, visual joint quality confirmation, elimination of plating bleed-out, a vibration-resistant solid joint, quality consistency from joint to joint, and high corrosion resistance throughout the joint. The system is a simple punch and die operation that automatically feeds, punches, inserts, and locks the self-piercing, flush-mounted Fas-ner to produce a solid joint in one high-cycle operation.


Emissions control

Legislation calls for a dramatic decrease in emissions, especially NOx from heavy-duty diesel engines. The SINOx system from Siemens Ceramics and Hydraulik-Ring GmbH (a Siemens company) represents the technology to reduce NOx and HC emissions by approximately 80%, and PM emissions by 20-40%, thereby fulfilling the expected European NOx emissions requirements of 2008 even with today's engine technology and calibration. The companies combine their expertise to provide the major components of the SINOx system: the SCR catalyst, catalyst housing, urea dosing control unit, and SCR system electronic unit with control logic software.


Crash wall

BIA offers a turnkey measurement system that helps quantify the structural integrity of vehicles in full-frontal, frontal-offset, and side-impact crash test conditions. The system consists of a load cell matrix of 64 independent tri-axial cells that is installed to a frontal barrier face (FMVSS 208) or movable barrier (FMVSS 214). The load cells are capable of impact forces of up to 400 kN (89,900 lb) in the x-axis and 150 kN (33,720 lb) each in the y- and z-axis, with a total accuracy of 0.5% across the measurement range. Test parameters such as load-cell range and auto or manual calibration are easily configured using a Windows-based PC. The data-acquisition system is installed on top or inside of the load-cell structure to minimize complex cabling and associated losses in accuracy. Communication with the control system is made via fiber-optic cable using IEEE or Ethernet communications protocol.


Optical sensor

The Correvit HS-CE optical sensor system from Corrsys-Datron Sensorsystems, Inc. simultaneously measures roll angle, pitch angle, longitudinal speed or vectoral velocity, transverse speed, and drift angle. The sensor is the first measurement device to incorporate the Correvit pupil-splitting technology that allows measurement of movement in three axes with a single optical path. This capability provides increased accuracy, a measurement field diameter of 30 mm (1.2 in), and a local resolution of up to 0.5 mm (0.02 in).
