Solution Approach 1:

The patent designs optical transceivers that integrate multiple functions including data transmission, reception, and processing capabilities within single modular units. These universal transceiver modules can be configured for different applications and scenarios, reducing overall system complexity despite the advanced functionality they provide.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent divides the optical communication system into separate functional modules including transceivers, beam steering mechanisms, and signal processing units. This segmentation allows each component to be optimized independently and facilitates modular deployment, reducing the complexity burden of implementing secure optical communication.

Inventive Principle:

If beam steering is implemented to maintain line-of-sight communication, then communication reliability is improved, but device complexity and power consumption increase

Engineering Contradiction:

Improvecommunication reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic beam steering mechanisms that automatically adjust the direction of optical beams to maintain line-of-sight communication as XR devices move. This dynamic adaptation ensures continuous reliable communication without requiring manual intervention or complex mechanical structures, as the system dynamically tracks and adjusts beam directions based on real-time device positions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs feedback mechanisms where the system continuously monitors the position and orientation of XR devices and adjusts beam steering accordingly. This closed-loop feedback control maintains optimal line-of-sight communication links while minimizing the complexity of beam steering implementation by using software-based control rather than complex mechanical systems.

Inventive Principle:

AI summary

An extended reality headset has light-based communication transceivers coupled to the extended reality headset. The relative position of a remote transceiver with respect to the current position and orientation of the extended reality headset is determined. A line-of-sight is calculated from the light-based communication transceivers to the remote transceiver. The light-based communication transceivers emit a light-based communications beam in accordance with the calculated line-of-sight. The light-based communications beam is adjusted in response to changes to the relative position of the remote transceiver with respect to the current position and orientation of the extended reality headset.
