发明名称 MULTIDIRECTIONAL COMMUNICATION SYSTEM
摘要 Various of the disclosed embodiments incorporate wavelength-shifting (WLS) materials to facilitate high data rate communication. Some embodiments employ a waveguide incorporating such WLS materials to receive a wireless signal from a source. The signal may be, e.g., in the optical or ultraviolet ranges, facilitating a ˜10 Gbps data rate. Because the WLS material is sensitive in all directions, the source may be isotropic or wide-angled. The WLS material may be shaped into one or more “bands” that may cover an object, e.g., a head-mounted display. A detector may be coupled with the bands to receive the wavelength-shifted signal and to recover the original signal from the source. The WLS material may be modified to improve the waveguide retention, e.g., by incorporating layers of material having a different reflection coefficient or a Bragg reflector.

主权项 1. An apparatus for communicating with a host system, comprising: a wavelength-shifting (WLS) material configured to at least partially: absorb electromagnetic radiation in a first wavelength band transmitted from athe host system;emit electromagnetic radiation in a second wavelength band;confine the electromagnetic radiation in the second wavelength band to travel within the WLS material; anddirect the electromagnetic radiation in the second wavelength to a detector coupled to the WLS material.
