Abstract: Embodiments of the disclosure describe data transmission via a touchscreen display of a mobile computing device. The mobile computing device includes a peripheral component, integrated into a touchscreen display surface housing, and a plurality of photonic pulse transmitters and receivers disposed on edges of the touchscreen display surface. One or more receivers receive pulses from the photonic pulse transmitters for detecting user touch inputs on the touchscreen display surface. A photonic pulse modulator modulates a pulse to be transmitted from one of the photonic pulse transmitters based, at least in part, on peripheral component data. A photonic pulse demodulator demodulates the modulated pulse received by the pulse detector(s) to retrieve the peripheral component data. By utilizing these pulse transmitters/receivers, used for user touch input detection, to also exchange data via modulated light, the bezel area around the touchscreen display surface may be reduced.

Abstract: Aspects of the disclosure include vehicle positioning. In at least certain aspects, light sources can be disposed around a vehicle providing 360-degree coverage. Each of the light sources can be referred to as a beacon and can be configured to emit modulated light conveying information that can permit vehicle positioning. In addition, 360-degree camera coverage about the car can be provided by functionally coupling a respective camera with each of such beacons. In other aspects, the embedded beacons can be operated in various modes, including a mode in which at least one of the embedded beacons can emit light in order to augment existing ambient light in order to assist with driving under certain environment conditions; and a second mode in which several of the embedded beacons can emit modulated light that can be accessed by other vehicles in order to determine cooperatively the relative position of the vehicles.

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: Examples are disclosed for a mobile device to wirelessly dock to a device. In some examples, a mobile device may receive an indication to identify a device for wirelessly docking. The mobile device may gather identification for possible devices to wirelessly dock. A ranging technique may be implemented using a given frequency band to identify a device within a shortest distance from the mobile device from among the possible devices. The device having the shortest distance may be selected and a wireless dock may then be established. Other examples are described and claimed.

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 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.

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: Embodiments may communicate via an electromagnetic radiator, or light source, that can be amplitude modulated such as light emitting diode lighting via receivers that can determine data from light received from the radiator. Some embodiments decode data of a packet transmitted from modulated lighting by means of a device with a low sampling frequency such as a relatively inexpensive camera. Many embodiments determine locations of start frame delimiters in packets. Several embodiments implement repeat decoding on packets of the same data to reduce packet error rates. Some embodiments are intended for indoor navigation via photogrammetry using self-identifying light anchors. In many embodiments, the data signal may be communicated via the light source at frequencies causing flicker that is not perceivable to the human eye.

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.

Abstract: Methods and systems to determine at multi-dimensional coordinates of an object based on propagation delay differences of multiple signals received from the object by each of a plurality of sensors. The signals may include optical signals in a human visible spectrum, which may be amplitude modulated with corresponding frequency tones. An envelope may be detected with respect to each of the sensors, and signals within each envelope may be separated. A phase difference of arrival may be determined for each of the signals, based on a difference in propagation delay times of the signal with respect to multiple sensors. The phase differences of arrival may be converted to corresponding distance differences between a corresponding transmitter and the corresponding sensors. A linear distance and a perpendicular offset distance may be determined from a combination the distance differences, a distance between the corresponding transmitters, and a distance between the corresponding sensors.

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.

Abstract: A Multiple-Input-Multiple-Output (MIMO) data transmit-receive protocol that can be used with an arbitrary light array, including one or more lights, that transmits light to a light receiver having an image sensor, including a large number of light sensing pixels. The protocol supports two primary protocol or coding modes in which the light array may transmit: spatial coding and space-time coding. The protocol is constructed upon the use of efficient start-frame-delimiters (SFDs) and data-delimiters (DDs). The lights may be implemented to transmit the SFDs, the data delimiters, and data bits as modulated light. The light may be modulated in accordance with a modulation technique referred to as frequency shift on-off keying (FSOOK).
