A multi-functional adjustable base for a sun shading umbrella having a supporting stem includes a base support, a stem rotary member rotatably supported by the base support and securely holds the supporting stem, and a controlling arrangement mounted on the base support and communicated with the stem rotary member for selectively rotating or locking up the stem rotary member. The controlling arrangement includes a transmission member, which is supported by the base support, having an engaging end adapted for engaging with the stem rotary member, and a paddle pivotally and integrally connected to the transmission member and extended outside the base support for switching the stem rotary member into one of the two states--a freely rotating state and a locked state, wherein in the freely rotating state, the stem rotary member is free to rotate with respect to the base support, while in the locked state, the stem rotary member is locked in position.

The apparatus for remote inspection of claim 3, wherein said electronic circuit comprises at least one detector for the at least one predetermined internal condition, said at least one detector for the at least one predetermined internal condition being adapted to initiate a signal to the remote central station upon detection of the at least one predetermined internal condition. 5. The apparatus for remote inspection of claim 4, wherein said at least one detector for the at least one predetermined internal condition comprises said fire extinguisher gauge for detecting the out-of-range pressure condition of fire extinguishing material contained within the volume of the fire extinguisher tank of the fire extinguisher at the fire extinguisher station. 6. The apparatus for remote inspection of claim 5, wherein said fire extinguisher gauge comprises a gauge pointer and a gauge scale, said gauge pointer being moveable relative to said gauge scale for indication of pressure, and said apparatus further comprises a magnet mounted to said gauge pointer and at least one sensor responsive to proximity of said magnet as the tank approaches an out-of-range pressure condition. 7. The apparatus for remote inspection of claim 6, wherein said at least one sensor comprises at least one Hall Effect sensor. 8. The apparatus for remote inspection of claim 7, wherein the out-of-range pressure condition comprises a low-pressure condition, and said at least one detector comprises at least one Hall Effect sensor positioned to detect the low-pressure condition. 9. The apparatus for remote inspection of claim 7, wherein said out-of-range pressure condition comprises a low-pressure condition and a high-pressure condition, and said at least one sensor comprises at least one Hall Effect sensor positioned to detect the low-pressure condition and at least one Hall Effect sensor positioned to detect the high-pressure condition. 10. The apparatus for remote inspection of claim 7, claim 8, or claim 9, wherein said at least one Hall Effect sensor is mounted generally in a plane of said gauge scale. 11. The apparatus for remote inspection of claim 10, wherein said at least one Hall Effect sensor is mounted at a rear surface of said gauge scale. 12. The apparatus for remote inspection of claim 3, wherein the predetermined out-of-range pressure condition comprises a low-pressure condition. 13. The apparatus for remote inspection of claim 3 or claim 12, wherein said out-of-range pressure condition comprises a high-pressure condition. 14. The apparatus for remote inspection of claim 3, wherein said electronic circuit comprises at least one detector for the at least one predetermined external condition, said at least one detector for the at least one predetermined external condition being adapted to initiate a signal to the remote central station upon detection of the at least one predetermined external condition. 15. The apparatus for remote inspection of claim 14, wherein the at least one predetermined external condition comprises movement of the fire extinguisher relative to its installed position at the fire extinguisher station. 16. The apparatus for remote inspection of claim 15, wherein the at least one predetermined external condition comprises removal of the fire extinguisher from its in
