These workloads saturate the<br>CPU\/GPU, causing excessive heat, elevated power draw and<br>eventual thermal throttling, which in turn collapse situational<br>awareness (SA) in safety-critical missions. Dynamic voltage and<br>frequency scaling (DVFS) is a well-known technique that adjusts<br>voltage\u2013frequency levels at runtime to reduce heat generation<br>and power consumption [1]. However, conventional DVFS governors are application-agnostic and often fail to prevent thermal<br>throttling on mobile devices [1]. Moreover, virtual and augmented<br>reality tasks can push smartphone components past their thermal<br>design power by 20\u201380 % and raise CPU\/GPU temperatures<br>beyond 70 \u25e6C, leading to degraded performance and discomfort<br>[2].<br>This paper introduces ThermoGuard, a power\u2013thermal control<br>framework tailored for AR RF operations on wearables. ThermoGuard combines application-aware DVFS with an overlay throttling module that dynamically reduces the density of rendered<br>overlays to maintain mission utility while staying within thermal<br>budgets. Through step-load and hot-ambient experiments, we<br>show that ThermoGuard prevents thermal throttling on Jetson<br>Xavier NX and Pixel-8 hardware, sustaining median SA latencies<br>under 50 ms at &lt;1W while CPU temperatures remain below<br>70 \u25e6C. Compared with baseline governors, ThermoGuard improves end-to-end utility by 27 % under sustained high loads.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"623\" height=\"555\" src=\"https:\/\/neurosphere-2.tail52f848.ts.net\/wordpress\/wp-content\/uploads\/2025\/09\/image-81.png\" alt=\"\" class=\"wp-image-3563\" srcset=\"https:\/\/neurosphere-2.tail52f848.ts.net\/wordpress\/wp-content\/uploads\/2025\/09\/image-81.png 623w, https:\/\/neurosphere-2.tail52f848.ts.net\/wordpress\/wp-content\/uploads\/2025\/09\/image-81-300x267.png 300w\" sizes=\"auto, (max-width: 623px) 100vw, 623px\" \/><\/figure>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Augmented reality (AR) and radio-frequency (RF)sensing pipelines demand high frame rates and continuousinference on mobile hardware.
