Thus, a highly-accurate automatic fall detection system is likely to be a significant part of the living environment for the elderly to expedite and improve the medical care provided while allowing people to retain autonomy for longer.

The above is the long sentence.

(1) what's the meaning of 'expedite' here?

(2) 'and improve the medical care', what's it before 'and'? I mean which part is and to 'improve the medical care'

(3) what's the meaning of 'while' here?

  • Basic meaning: The system is likely to be a part, in order to e&i the care, while allowing longer autonomy. Inserting commas after elderly and after provided is necessary; leaving them out of the written version is the cause of the problem. "Expedite X" means 'make X happen faster'. The and connects the two verbs expedite & improve, which both take the medical care provided as direct object. While here means 'and at the same time.' – John Lawler Jun 29 '14 at 18:14
  • The whole sentence needs a rewrite, since the first and second halves are at syntactic cross purposes, as if (what often happens) the writer began with one syntactic plan, switched to another, and never fully followed through with the change. From "to expedite and improve" forward we have a perfectly good statement of the purpose of the action (as @JohnLawler clarifies by inserting "in order" above); but the main clause preceding has no action at all. – Brian Donovan Jun 29 '14 at 18:24

    I'd be at least as likely to use whilst as while there, but I think all three sub-questions are effectively General Reference. – FumbleFingers Jun 29 '14 at 18:25

Consider:

Thus, a highly-accurate automatic fall detection system is likely to be a significant part of the living environment for the elderly. Such a system can expedite and improve the medical care and allow people to retain autonomy for a longer period.

  • -1 Sorry, I down voted this because it's NOT an analysis of the sentence which is what the author asked for. Had he asked for a rewrite I would have up voted. – Frank Jun 30 '14 at 7:25

    @Frank ...........That is O.K. ............I felt the analysis could be avoided by the re-write. – Gary's Student Jun 30 '14 at 11:15
