1. For use by a time-of-flight (TOF) system that emits and detects infrared (IR) light, a method for substantially reducing interference that the TOF system may cause to at least one other system that is configured to wirelessly receive and respond to IR light signals, the method comprising: emitting IR light having a low frequency (LF) power envelope that is shaped to substantially reduce frequency content within at least one frequency range known to be used by at least one other system configured to wirelessly receive and respond to IR light signals, wherein at least a portion of IR light being emitted is radio frequency (RF) modulated IR light; and detecting at least a portion of the emitted RF modulated IR light that has reflected off one or more objects.
