I'm having trouble finding the best translation for "poised".  Which of these meanings is best:

1. (of a person) composed, dignified, and self-assured. 
2. being in balance or equilibrium: a balloon poised on the nose of a seal. 
3. teetering or wavering: to be poised on the brink of disaster. EXPAND
4. hovering or suspended in or as in midair: a bird poised in flight; a helicopter poised overhead. 
Is there any other meaning not included here?
