Abstract: One or more system, apparatus, method, and computer readable media is described below for conveyance of hidden image data between a display and a camera. In some embodiments, modulating a display pixel refresh rate a predetermined amount relative to a target camera frame rate conveys hidden image data. In further embodiments, a camera module is employed to detect one or more changes in state and/or logic level associated with the pixel refresh rate modulation. The logic levels are then decoded to deduce the hidden image data. In some embodiments, a visually perceptible representation of the hidden image data is then output to a output panel. For example, in one exemplary embodiment the hidden image data includes a pixel value indicative of a color that is to be output to one or more pixel of a camera viewer.

Abstract: A mobile device includes an inertial navigation system (INS) to measure inertial quantities associated with movement of the device, and estimate a kinematic state associated with the movement based on the measured inertial quantities. The device includes a light receiver to record light beams originating from lights at respective image positions in a sequence of images. The device photogrammetrically determines its position relative to the originating lights based on predetermined real-world positions and corresponding image positions of the lights. The device corrects the estimated kinematic state based on the photogrammetrically determined position, to produce a corrected estimated kinematic state.

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 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. 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.

Abstract: A light receiver records images of light beams originating from a neighborhood of lights, and demodulates identifiers (IDs) from them at determined image positions. The receiver retrieves a set of neighbor IDs for each demodulated ID and a real-world position of the corresponding light. The receiver cross-references the demodulated IDs against the retrieved sets of neighbor IDs to reveal errors in the demodulated IDs. The receiver corrects the errors to produce correct IDs each indexing a real-world position that is correctly matched to one of the determined light beam positions. The receiver determines a position of the receiver relative to the light transmitter based on the correctly matched real-world and determined light beam positions.

Abstract: A light transmitter transmits multiple light packets, each formatted to include a same message comprising a series of bits, each bit represented as light that is intensity modulated over a bit period at a frequency indicative of the bit. 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.

Abstract: Optical wireless communication techniques are described and claimed. In one embodiment, the disclosure relates to method and apparatus to provide optical signaling with visible light having variable pulse position modulation (VPPM). The optical signal includes a Start Frame Delimiter (SFD) which indicates beginning of an asynchronous optical signaling. The VPPM signaling includes a lower frequency time varying amplitude component that when subsampled by a low frame rate camera results in alias induced flicker or blinking. Such signals are quickly recognizable as signals with modulated data. In another embodiment, the disclosure provides a system, device and method for decoding a Start Frame Delimiter (SFD) to indicate arrival of incoming VPPM optical data.
