The bridge should be fitted to increase surface contact using rigid nose support if possible.

The footpad of each landing gear contained a 67in cm-long surface contact sensor probe, which signaled the commander to switch off the descent engine.

The stud contact system or surface contact system was used with some tramway systems.

As it descends, it warms again through surface contact or conductivity and the cycle repeats.

Each cell of the morula, called a blastomere, increases surface contact with its neighbors in a process called compaction.
