Abstract
Systems and methods are described that relate to measuring relative positions of, or distance between, a helmet-mountable device and a head-mountable device. The helmet-mountable device includes a radio frequency (RF) source of a millimeter wave signal comprising millimeter wave radiation. The head-mountable device includes a plurality of rectenna devices. Each rectenna device of the plurality of rectenna devices converts millimeter wave radiation emitted by the RF source into a direct current (DC) electrical signal. The head-mountable device includes a memory and at least one processor. The at least one processor executes instructions stored in the memory so as to carry out operations, which include receiving, from each rectenna device of the plurality of rectenna devices, a respective DC electrical signal. The operations also include storing, in the memory, information indicative of the respective DC electrical signals.
