AN APPARATUS FOR USE IN INDUCTIVE SENSING

An apparatus (20) for use in inductive sensing includes a loop antenna (26) and a signal generator (24) for driving the antenna, these forming a resonator circuit (22). The resonator circuit is drivable in a drive state in which the antenna is driven at resonance to thereby generate electromagnetic...

More Information
Summary:An apparatus (20) for use in inductive sensing includes a loop antenna (26) and a signal generator (24) for driving the antenna, these forming a resonator circuit (22). The resonator circuit is drivable in a drive state in which the antenna is driven at resonance to thereby generate electromagnetic signals. The arrangement further includes a switching means (28) for switchably inhibiting the drive state of the antenna. This allows in use controllable switching of the antenna in and out of the drive state to thereby control switching signal generation on and off. 一种在感应式感测中使用的装置(20)包括：环形天线(26)和用于驱动所述天线的信号生成器(24)，这些形成谐振器电路(22)。所述谐振器电路可在驱动状态中驱动，在所述驱动状态中，所述天线在谐振下被驱动，从而生成电磁信号。布置还包括用于可切换地禁用所述天线的所述驱动状态的切换模块(28)。这允许在使用中可控地切换所述天线进出驱动状态，从而控制将信号生成开启和关闭。
