Abstract: A light transmitter to transmit 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: 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: An apparatus for light wave communications is described herein. The apparatus includes an image sensor and a region of interest (ROI) sub-sampler. The image sensor is to receive a first low frequency data stream from a light source. Additionally, data from the ROI sub-sampler is used to configure the image sensor to receive a second data stream from the light source.

Abstract: A light transmitter transmits multiple light packets, each formatted to include a predetermined phase synchronization field (PSF) and a same message comprising a series of bits. The PSF and each bit are each represented as light that is intensity modulated over a bit period at a corresponding frequency. The light packets are transmitted at different start-times to cause a receiver to sample each packet with a different phase of a fixed, asynchronous sample timeline. The PSF and message are demodulated from each of the sampled light packets. If the demodulated PSF matches the predetermined PSF, then the corresponding demodulated message is declared valid.
