WiFi-based device localization is a key technology for smart applications, while most of which rely on LoS signals to work. However, in real-world indoor environments, very few are usable accurate localization. This paper presents Bifrost , novel hardware-software co-design cope with this practical problem. The core idea reinvent WiFi provide sufficient signals. Specifically, we present low-cost plug-in design leaky wave antenna (LWA) that can generate orthogonal polarized signals: On one...
In this work, the dynamic response of clamped sandwich beams with fibre-metal laminate face-sheets under low-velocity impact is analytically and numerically studied. Analytical solutions for FML heavy-mass are developed based on modified rigid-plastic material approximation. results compared numerical ones, there a good agreement between two. The effects foam strength, strength ratio metal layer to composite layer, volume fraction structural discussed in detail. It shown that has substantial...
