Multijurisdictional Co Location SAR Evaluation Limits for Portable Host Devices
Multijurisdictional co-location SAR evaluation requires host-level total exposure ratio analysis and spatial decoupling to ensure global market clearance.
DASY Robotics System
Meaning
Automated precision instrumentation provides the positioning accuracy required to map electromagnetic energy absorption in humanoid models. The dasy robotics system employs high resolution probes attached to a multi axis mechanical arm to measure field strength within a phantom shell. Integration into a laboratory environment ensures that the probe tip maintains a constant distance from the internal surface during the scanning process even when the geometry is complex.
Data acquisition occurs at high speeds to allow for the completion of full three dimensional scans within a standard test window.
Movement Precision
Calibration routines ensure the mechanical arm follows a programmed path with sub millimetre repeatability. This dasy robotics system relies on optical sensors to detect the proximity of the probe to the enclosure walls. Stable positioning prevents physical contact that might damage the delicate sensors.
Hardware Interface
Connection points between the controller and the robotic arm use shielded cables to prevent interference with the measurement data. A dedicated controller manages the dasy robotics system by executing pre programmed scan patterns based on the device under test geometry. Real time feedback loops correct for any deviation in the expected path.
Compliance Reporting
Final data sets produced by the assembly allow engineers to verify that a product meets safety limits for human exposure to radio frequency energy. The dasy robotics system generates a detailed plot of energy distribution across the sampled area. Certification bodies rely on these results to issue market access approvals.
