Engineering Contradiction Analysis
1Measurement precision
If raw-sensor-data sharing (RDS) is used to transmit sensor data, then the receiver device can access nearly all information acquired by the sensor for high accuracy processing, but high communication bandwidth is required which may not be satisfied by communication technology particularly in dense sensor networks
Solution Approach 1:
The patent extracts only the essential information needed for object detection from the raw sensor data. Instead of transmitting complete raw sensor data, the system identifies and transmits only the relevant features and parameters required for accurate object detection, thereby reducing communication bandwidth requirements while maintaining detection accuracy.
Solution Approach 2:
The patent applies different processing and transmission strategies to different regions or types of sensor data based on their importance for object detection. Critical regions containing potential objects are processed with higher fidelity and transmitted with more detail, while less critical regions are compressed or aggregated, optimizing the balance between bandwidth usage and detection accuracy.
2Quantity of substance
If object-based sensor data sharing (ODS) is used to transmit extracted objects and their attributes, then communication bandwidth requirements are reduced, but some useful data is lost and cannot be considered by the receiver device
Solution Approach 1:
The patent performs preliminary processing at the sender device to extract and preserve critical object information before transmission. By pre-identifying and encoding essential object attributes and features in advance, the system ensures that all useful data needed for accurate object detection is captured and transmitted, preventing information loss that would occur with simpler ODS approaches.
Solution Approach 2:
The patent introduces an intermediary processing layer that bridges between raw sensor data and final object detection. This intermediary layer at the sender device performs intelligent data selection, feature extraction, and encoding to ensure that all relevant information is preserved in the transmitted data, allowing the receiver to reconstruct complete object information without losing useful data.
3Measurement precision
If object detection technique is applied to sensor data to detect objects and their attributes, then the data can be processed with high accuracy, but additional computational processing is required at the sensor device
Solution Approach 1:
The patent segments the computational workload between the sensor device and the receiver device. The sensor device performs only essential preliminary processing to identify and extract critical object information, while more complex detection and analysis operations are performed at the receiver device. This segmentation reduces the computational burden and complexity at the resource-constrained sensor device while maintaining high object detection accuracy.

AI summary
Sensor data may be encoded for transmission to a receiver by applying an object detection technique to the sensor data to detect an object in the sensor data and to determine one or more attributes of the object, encoding the sensor data to obtain encoded sensor data, wherein the encoding comprises applying a data compression technique to the sensor data, wherein the data compression technique is configurable by one or more compression parameters, wherein applying the data compression technique to the sensor data comprises selecting at least one of the one or more compression parameters based on the one or more attributes of the object, generating object data indicative of the one or more attributes of the object, and sending the encoded sensor data and the object data to the receiver to enable the receiver to select one or more decompression parameters of a data decompression technique based on the one or more attributes of the object.
