An example playback device includes a housing having a front side, a back side, a first end, and a second end. The playback device also includes an IR receiver positioned on the front side of the housing, a first IR emitter positioned on the back side of the housing and oriented such that a first IR signal emitted from the first IR emitter is directed toward the second end of the housing, and a second IR emitter positioned on the back side of the housing and oriented such that a second IR signal emitted from the second IR emitter a) is directed toward the first end of the housing and b) crosses the first IR signal emitted from the first IR emitter. The first and second IR emitters are communicatively coupled to the IR receiver within the housing and configured to retransmit an IR control signal received by the IR receiver.

In a system that reduces interference between devices that transmit infrared signals, a first device transmits a first infrared signal to a second device during a first time period. The second device determines a command encoded by the first infrared signal. When the first time period has elapsed, the first device ceases transmission during a second time period. The second device transmits the second infrared signal to a third device during the second time period. As a result, transmissions from the second device to a third device are not affected by interference from transmissions by the first device. Selected signals from the first device may be permitted during the second time period, such as signals to cancel previous commands or to queue additional commands.

A display method includes capturing, by an imaging sensor, a still image lit up by a transmitter that transmits a signal by luminance change of light as a subject to obtain a first captured image with a first exposure time. The still image is captured to obtain a second captured image with a second exposure time which is longer than the first exposure time. The display method further includes decoding the signal form the first captured image, and determining whether identification information included in each of a plurality of sets is identical to the decoded signal. Further, the method also includes reading the video included in each of the sets with the identification information identical to the decoded signal, and superimposing the video on a target region corresponding to the subject in the second captured image for display on a display.

The present disclosure provides an optical tag-based information apparatus interaction method and system. The method includes: using a terminal device to perform image acquisition on an optical tag at a relative fixed position to an information apparatus so as to determine a position and an attitude of the terminal device relative to the optical tag; determining, in conjunction with a predetermined position of each information apparatus relative to the optical tag, the position of the terminal device relative to each information apparatus; acquiring an imaging position of each information apparatus on a display screen of the terminal device, and displaying an interactive interface of each information apparatus at the imaging position thereof on the display screen, such that an interactive operation can be performed on each information apparatus. The disclosure allows a user to control an information apparatus in a field of view anytime and anywhere, and interact with the device as What You See Is What You Get (WYSIWYG).

An optical interconnect computing module having free space optical interconnects that form communication links with other systems with like optical interconnects and with computer blades contained within the computing module. The computing module adapts to changes in the position and orientation and other factors of the optical interconnects. The optical interconnects utilize solid-state electronic and optoelectronic components and optical components. The ability to adapt is controlled by an algorithm implemented in software, firmware and logic circuits. Computing modules within an equipment rack and between equipment racks as well as blades contained within a computing module may experience changes in position and orientation due to installation misalignment, servicing of equipment, vibrations, floor sagging, thermal expansion and contraction, earthquakes, line-of-sight obstructions, manufacturing imperfections and other sources.

A wireless communication system comprises a base station and one or more relay docks and transmits directional wave signals between components using high frequency waves, such as millimeter waves. A beam forming decision engine utilizes position information collected from one or more position or motion sensors of a user device to determine a direction in which to form a directional wave signal being transmitted between components of the wireless communication system.
