Abstract: Embodiments may provide a way of communicating via an electromagnetic radiator, or light source, that can be amplitude modulated such as light emitting diode (LED) lighting and receivers or detectors that can determine data from light received from the amplitude modulated electromagnetic radiator. 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.

Some embodiments may provide a waveform in the form of chips at a chipping clock frequency that switch a light source between on and off states to communicate via light sources that can be amplitude modulated such as LED lighting. Some embodiments may provide a method of transmitting the waveform via modulated LED lighting. Some embodiments are intended for indoor navigation via photogrammetry (i.e., image processing) using self-identifying LED light anchors.

Abstract: Various embodiments are directed to techniques for employing a camera to receive multiple light transmissions conveying at least identifying data from multiple body-carried devices to enable locations of those devices within a venue to be determined and transmissions to individual ones of those devices to be made. An apparatus to communicate via light transmissions includes an analysis component to analyze a set of consecutively captured frames of a portion of a venue to determine whether a light source present in at least a predetermined number of the consecutively captured frames is a light transmission from a body-carried device located within the portion of the venue, and to demodulate the light transmission to retrieve an identification (ID) data associated with the body-carried device from the light transmission; and a communications component to employ the ID data to wirelessly transmit a command to the body-carried device. Other embodiments are described and claimed.

Abstract: A light array includes lights that transmit modulated light to indicate their unique light identifiers (IDs) and lights that transmit unmodulated light. A light receiver records images of the light array and recovers the light IDs from the modulated light. The light receiver uses the IDs to retrieve a light map representative of the light array. The receiver aligns the retrieved light map with the recorded images of the light array, and accesses real-world positions of all of the light in the light array, as deployed, based on the aligned light map. The light receiver determines a 3-dimensional position of the light receiver relative to the light array.
