Orbiter Boom Sensor System
The Orbiter Boom Sensor System (OBSS) was a 50-foot (15.24 m) boom carried on board NASA's Space Shuttles. The boom was grappled by the Canadarm and served as an extension of the arm, doubling its length to a combined total of 100 feet (30 m). At the far end of the boom was an instrumentation package of cameras and lasers used to scan the leading edges of the wings, the nose cap, and the crew compartment after each lift-off and before each landing. If flight engineers suspected potential damage to other areas, as evidenced in imagery captured during lift-off or the rendezvous pitch maneuver, then additional regions could be scanned. The OBSS was introduced to the shuttle fleet with STS-114, the "Return to Flight" mission executed by ''Discovery'', and was flown on every mission after that until the retirement of the Space Shuttle fleet in 2011. It was used to inspect the shuttle for damage to the heat shield, officially called the Thermal Protection System (TPS), that could jeopar ...

Overlapping Basic Service Set
In IEEE 802.11 wireless local area networking standards (including Wi-Fi), a service set is a group of wireless network devices which share a ''service set identifier'' (''SSID'')—typically the natural language label that users see as a network name. (For example, all of the devices that together form and use a Wi‑Fi network called ''Foo'' are a service set.) A service set forms a logical network of nodes operating with shared link-layer networking parameters; they form one logical network segment. A service set is either a ''basic service set'' (''BSS'') or an ''extended service set'' (''ESS''). A ''basic service set'' is a subgroup, within a service set, of devices that share physical-layer medium access characteristics (e.g. radio frequency, modulation scheme, security settings) such that they are wirelessly networked. The basic service set is defined by a ''basic service set identifier'' (''BSSID'') shared by all devices within it. The BSSID is a 48-bit label that confor ...
