Techniques for Raster Line Alignment in Light-Based Communication
Techniques are disclosed for providing proper raster line alignment of a camera or other light-sensing device of a receiver device relative to a transmitting light-based communication (LCom)-enabled luminaire to establish reliable LCom there between. In accordance with some embodiments, proper alignment can be provided automatically (e.g., by the receiver device and/or other suitable controller). In accordance with some embodiments, proper alignment can be provided by the user. In some instances in which a user is to be involved in the alignment process, the receiver device may be configured, for example, to instruct or otherwise guide the user in the process of properly aligning the receiver device relative to a given transmitting LCom-enabled luminaire.

Multiple panel luminaires for light-based communication
Multiple panel luminaires for light-based communication (LCom) and related techniques of use are disclosed. Each luminaire panel may comprise at least one solid-state light source, where the light sources are configured to output light. The luminaire may also include at least one modulator configured to modulate the light output of the light sources to allow for emission of LCom signals. The luminaire may also include a controller configured to synchronize timing of the LCom signals. In some cases, one panel may be configured to emit an LCom signal that is the inverse or duplicate of the LCom signal emitted from another panel. Panel signal inversion may be used to maintain a relatively constant level of light output from the luminaire and/or to create a virtual fiducial to provide orientation information. Using a multiple panel luminaire to transmit data may also result in improved data transmission rates and transmission reliability.
System and method for improved location accuracy
Systems and methods for improved location accuracy are provided. For example, some systems can include a location engine, and a plurality of location anchors. In some embodiments, each of the plurality of location anchors can transmit or receive signals to or from an object for determining an angular orientation of the object with respect to the plurality of location anchors, and based on the angular orientation, the location engine can estimate a location of the object. In some embodiments, each of the plurality of location anchors can transmit first signals to the location engine, the location engine can receive a second signal from an object, based on the first signals and the second signal, the location engine can determine a differential pressure between the plurality of location anchors and the object, and based on the differential pressure, the location engine can estimate an altitude of the object.
