An immersive experience system is provided. The immersive experience system has a processor that determines a position of a first head-mounted display. Further, the processor determines a position of a second head-mounted display. The processor also generates a first image for a first immersive experience corresponding to the position of the first head-mounted display. Moreover, the process encodes the first image into a first infrared spectrum illumination having a first wavelength. In addition, the processor generates a second image for a second immersive experience corresponding to the position of the second head-mounted display. Finally, the processor encodes the second image into a second infrared spectrum illumination having a second wavelength. The first wavelength is distinct from the second wavelength.

A drone network including a first drone including a first receiver, a first transmitter, and a first processor, and a second drone positionable at a distance from the first drone. The second drone includes a second receiver, a second transmitter, and a second processor. The first transmitter is configured to emit a signal towards the second drone for reception at the second receiver, and the second processor is configured to determine a minimum signal power for the signal to be processed at the second drone. The second transmitter is configured to emit a return signal towards the first drone for reception at the first receiver. The return signal contains minimum signal power data as determined by the second processor, and the first processor is configured to modulate the power of signals to be emitted towards the second drone from the first transmitter based on the minimum signal power data.

The disclosure provides for a method for reacquiring a communication link between a first communication device and a second communication device. The method includes using one or more processors of the first communication device to receive historical data related to the first communication device and an environment surrounding the first communication device. The one or more processors are then used to determine one or more trends in the historical data related to fading of the communication link. Based on the one or more trends, the one or more processors are used to determine a starting time and an initial search direction for a search for the communication link. The one or more processors then execute the search at the starting time from the initial search direction.

For example, an apparatus may include a computing device housing configured to house a motherboard of a computing device, the computing device housing including a base surface, a top surface opposite to the base surface, and a side-wall surface between the base surface and the top surface; and a light communicator configured to extend outward from the side-wall surface of the housing to communicate modulated light of a Visible Light Communication (VLC) transmission in a range of VLC directions.

An inter-vehicle optical network a plurality of lights, a plurality of optical sensors arranged around the perimeter of the vehicle configured to gather light data regarding a light intensity and gradient of incoming light, a controller communicatively coupled with the plurality of lights and the plurality of optical sensors. The controller configured to receive the light data from the plurality of optical sensors, detect in the light data a second flashing light pattern emitted by an adjacent vehicle with a rhythm, a color, and/or a light intensity, adjust the light level of each light of the plurality of lights based on the light data, adjust the first flashing light pattern in response to the second flashing light pattern, and adjust the first flashing light pattern to synchronize the first flashing light pattern with the second flashing light pattern.

An apparatus and method arbitrates bidirectional optical communication across optical link ends of independent controller area network buses. A mobile device has a battery management system and a first controller area network bus having a first optical link end, and a charging station has a second controller area network bus having a second optical link end. When the mobile device aligns with the charging station for charging, the optical links ends align to allow communication between the battery management system and the charging station regarding charging the battery. The arbiter apparatus is operationally interposed between the optical link ends and arbitrates the bidirectional communication by delaying a subsequent communication from one of the battery management system and the charging station until a dominant bit of a prior communication is released, thereby preventing the controller area network buses from transmitting simultaneously across the optical link ends.
