2. Ping test (engineering) - Wikipedia

   en.wikipedia.org/wiki/Ping_test_(engineering)

   A ping test is a physical test to determine the natural frequency of an object or assembly. [1] The test consists of instrumenting the object or assembly with measuring devices and then tapping it with another metallic object (usually a hammer.) The undamped system will then vibrate at its natural frequency.

3. Host controller interface (USB, Firewire) - Wikipedia

   en.wikipedia.org/wiki/Host_controller_interface...

   Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.

4. Drive shaft - Wikipedia

   en.wikipedia.org/wiki/Drive_shaft

   A drive shaft system weighs more than a chain system, usually 0.5–1 kg (1–2 lb) heavier. Many of the advantages claimed by drive shaft's proponents can be achieved on a chain-driven bicycle, such as covering the chain and sprockets. Use of lightweight derailleur gears with a high number of ratios is impossible, although hub gears can be used.

5. Spline (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Spline_(mechanical)

   A spline is a ridge or tooth [1] [2] [3] on a drive shaft that matches with a groove in a mating piece and transfers torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear.

6. Dunkerley's method - Wikipedia

   en.wikipedia.org/wiki/Dunkerley's_Method

   When an element of mass is offset from the axis of rotation, centrifugal force will tend to pull the mass outward. The elastic properties of the shaft will act to restore the “straightness”. If the frequency of rotation is equal to one of the resonant frequencies of the shaft, whirling will occur. In order to save the machine from failure ...

7. Automatic test pattern generation - Wikipedia

   en.wikipedia.org/wiki/Automatic_test_pattern...

   The logic values observed at the device's primary outputs, while applying a test pattern to some device under test (DUT), are called the output of that test pattern. The output of a test pattern, when testing a fault-free device that works exactly as designed, is called the expected output of that test pattern. A fault is said to be detected by ...
