Abstract:
1. An apparatus for at least one of sensing and emitting energy along an apparatus line of sight (LOS) with respect to said apparatus, comprising: at least two sensing/emitting units, each said unit adapted for at least one of sensing and emitting energy along a respective unit line of sight (ULOS); each sensing/emitting unit having an operative state, wherein the respective ULOS is pointed along said LOS for at least one of sensing and emitting energy, and a corresponding inoperative state, where the ULOS is pointed along a direction different from said LOS; a switching mechanism for switching between said units to selectively bring a desired unit exclusively into its respective operative state while concurrently bringing a remainder of said units each to a respective non-operative state; wherein a first said sensing/emitting unit is configured for at least one of sensing and emitting energy when an operational parameter associated with operation of said device is greater than an operational threshold and wherein a second said sensing/emitting unit is configured for at least one of sensing and emitting energy when said operational parameter is at or less than said operational threshold.
