A point of contact (POC) or single point of contact (SPOC) is a person or a department serving as the coordinator or focal point of information concerning an activity or program. A POC is used in many cases where information is time-sensitive and accuracy is important.
While landing under a parachute canopy, the jumper's feet strike the ground first and, immediately, they let their legs collapse, with the body following sideways to distribute the landing shock sequentially along five points of body contact with the ground: the balls of the feet; the side of the calf; the side of the thigh
Point contact diode, a type of semiconductor diode; Point of contact, a person serving as the focal point of information concerning an activity; Point-contact transistor, the first type of solid-state electronic transistor ever constructed, in 1947; Quantum point contact, a narrow constriction between two wide electrically conducting regions
Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines. The switch is automatically operated by a cam driven by the engine.

The first visual contact occurred at 11:30 am, April 25, in the village of Leckwitz, when First Lieutenant Arnold Kotzebue, from the 69th Infantry Division, saw a horseman, named Aitkali Alibekov, [2] riding into the courtyard of one of the houses on the central street. The patrol was on the west bank of the Elbe at 12:05, and across by 12:30.
Contact force or pressure increases the size of the a-spot which decreases the constriction resistance and the electrical contact resistance. [11] When the size of contacting asperities becomes larger than the mean free path of electrons, Holm-type contacts become the dominant transport mechanism, resulting in a relatively low contact ...
While point-contact transistors usually worked fine when the metal contacts were simply placed close together on the germanium base crystal, it was desirable to obtain as high an α current gain as possible. To obtain a higher α current gain in a point-contact transistor, a brief high-current pulse was used to modify the properties of the ...
