20100329230 | Avoiding beacon conflicts in multi-radio platforms - In a multi-radio platform that operates in two networks, both the announced beacon intervals and the actual beacon intervals in one network may be periodically increased and decreased in defined amounts so that the beacons will not overlap scheduled communications with the other network. The determination of how much and how often to adjust these beacon intervals may be based, at least partially, on the minimum increments in which the beacons intervals are permitted to be adjusted, and on the scheduled communications intervals of the other network. | 12-30-2010 |

Some embodiments may provide a method of transmitting/encoding data via modulated LED lighting and other embodiments may provide receiving/decoding data from the modulated LED lighting by means of a device with a low sampling frequency such as a relatively inexpensive camera (as might be found in a smart phone). Some embodiments are intended for indoor navigation via photogrammetry (i.e., image processing) using self-identifying LED light anchors. In many embodiments, the data signal may be communicated via the light source at amplitude modulating frequencies such that the resulting flicker is not perceivable to the human eye. | 10-16-2014 |

The light packets are transmitted at different start-times to establish different phases, one for each of the light packets, to permit a light receiver to sample each message at a different phase of a fixed sample timeline that is asynchronous to the bit period and the frequency. The light receiver samples the multiple light packets based on the sample timeline, to sample each received message at one of the different sample phases, then constructs a best series of bits based on the multiple demodulated messages. | 04-03-2014 |
