摘要： 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.

摘要： 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.

摘要： 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.

摘要： A light transmitter receives a low-rate data signal having a low data rate and a high-rate data signal having a high data rate that is greater than the low data rate. The transmitter includes a light source and a light modulator to modulate the light source based on logic levels of the high-rate data signal and logic levels of the low-rate data signal, to produce modulated light that concurrently conveys the logic levels of the low-rate data signal and the logic levels of the high-rate data signal.

摘要： Embodiments relate to communicating data by varying a frequency of an amplitude modulated light source. Embodiments may comprise logic such as hardware and/or code to vary a frequency of an amplitude-modulated electromagnetic radiator such as a visible light source, an infrared light source, or an ultraviolet light source. For instance, a visible light source such as a light emitting diode (LED) may provide light for a room in a commercial or residential building. The LED may be amplitude modulated by imposing a duty cycle that turns the LED on and off. In some embodiments, the LED may be amplitude modulated to offer the ability to adjust the intensity of the light emitted from the LED. Embodiments may receive a data signal and adjust the frequency of the light emitted from the LED to communicate the data signal via the light. In many embodiments, the data signal may be communicated via the light source at frequencies that are not perceivable via a human eye.
