    • A magnetic resonance technology is used to implement front and back proximity sensing capability for wireless devices such as a laptap device. For example, a high quality (Q) factor coil antenna may be embedded in a display, such as a liquid crystal display, of a first laptap device to detect other wireless devices (e.g., a second laptap) that are within coupling distance of the first laptap device. In this example, the second laptap device induces a sine wave signal to the first laptap device if the second laptap device is physically located at backside of the first laptap device. Otherwise, the second laptap device may induce a cosine wave signal to the first laptap device if the second laptap device is physically located at the front side of the first laptap device.
    • 使用磁共振技术实现诸如laptap设备之类的无线设备的前和后接近感测能力。 例如,高质量(Q)因子线圈天线可以被嵌入在第一搭接装置的显示器(例如液晶显示器)中,以检测处于耦合距离内的其它无线装置(例如,第二搭载器) 第一个laptap设备。 在该示例中,如果第二搭扣装置物理地位于第一搭扣装置的后侧,则第二搭扣装置向第一搭扣装置引发正弦波信号。 否则,如果第二牵引装置物理上位于第一牵引装置的前侧,则第二搭扣装置可以向第一牵引装置感应余弦波信号。
