Pressure measuring plates are useful for quantifying the pressure patterns under a foot over time but cannot quantify horizontal or shear components of the applied forces. [ 2 ] The measurements from a force platform can be either studied in isolation, or combined with other data, such as limb kinematics to understand the principles of locomotion.
A typical gait analysis laboratory has several cameras (video or infrared) placed around a walkway or a treadmill, which are linked to a computer. The patient has markers located at various points of reference of the body (e.g., iliac spines of the pelvis, ankle malleolus, and the condyles of the knee), or groups of markers applied to half of ...
Terrain contour matching, or TERCOM, is a navigation system used primarily by cruise missiles. It uses a contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter. A TERCOM system considerably increases the accuracy of a missile compared with inertial navigation systems (INS). The increased ...
The AM/FM/GIS system data model allow GIS architects to define a relationship model which consists of all the database tables and their dependencies. This is often combined with business rules to make the system more intelligent so that it can be utilized in running various analysis on the data. E.g. a gas pipeline GIS system can let the users ...
These include water, sand, crushed glass, dry ice and soda. High-pressure water blasting method uses 30,000 psi (210 MPa) water jet system on a truck equipped with vacuum heads to blast out the markings and suction up the water and debris back to the storage area of the truck. The method can remove markers at speeds of 2 mph (3.2 km/h).
The Central–Mid-Levels escalator and walkway system in Hong Kong is the longest outdoor covered escalator system in the world. The system covers over 800 m (2,600 ft) in distance and traverses an elevation of over 135 m (443 ft) from bottom to top. It opened in 1993 to provide an improved link between Central and the Mid-Levels on Hong Kong ...
The Cincinnati Skywalk was a series of walkways, primarily indoors and elevated, that allowed pedestrians to traverse downtown Cincinnati, Ohio, United States. [ 1 ] Built in segments starting in 1971, the 1.3-mile (2.1 km) skywalk was completed in 1997 at a total cost of more than $16 million. [ 1 ]
The Commercial Joint Mapping Toolkit, or CJMTK is the DoD standard mapping toolkit for DoD C2I Programs of Record. It is a replacement for the previous United States Department of Defense (DoD) Joint Mapping Toolkit (JMTK) that utilizes commercial off-the-shelf (COTS) components.
