    • The present invention relates to a hearing instrument which comprises: (a) a housing; (b) an RF receiver; (c) plurality of conductive elements, each conductive element has the form of a plate, is positioned on said housing so it provides coupling with the device wearer's skin while the instrument is in use, thereby forming an antenna element together with the wearer's body; (d) a switch for each conductive element, for connecting or disconnecting the respective antenna element from the receiver; (e) a controller for periodically initiating a testing cycle wherein during said cycle: (e.1) the controller sequentially scans said switches by closing each time another switch, thereby to connect each time a respective antenna element to said receiver; (e.2) each time said antenna switching is performed and a specific antenna element is connected to the receiver, the controller samples and stores a respective quality indication signal which is indicative of the quality of the received signal by said receiver via said respective antenna; (e.3) the controller inspects all said stored indications, determines from all said stored indications the one that relates to a best quality signal, and connects the antenna element which corresponds to said best quality signal to said receiver for a time duration which is substantially longer than the duration of said testing cycle, until performance of a next testing cycle.
    • 本发明涉及一种听力仪器,其包括:(a)壳体; (b)RF接收机; (c)多个导电元件,每个导电元件具有板的形式,位于所述壳体上,从而在仪器使用时提供与设备佩戴者皮肤的联接,从而与佩戴者的身体一起形成天线元件; (d)用于每个导电元件的开关,用于将相应的天线元件与接收器连接或断开; (e)用于周期性地启动测试循环的控制器,其中在所述循环期间:(e.1)控制器通过每次关闭每个另一个开关来顺序地扫描所述开关,从而每次将相应的天线元件连接到所述接收器; (e.2)每次执行所述天线切换并且将特定天线元件连接到接收机时,控制器通过所述相应天线采样并存储指示所述接收机的接收信号质量的相应质量指示信号 ; (e.3),控制器检查所有存储的指示,从所有所存储的指示中确定与最佳质量信号相关的指示,并将对应于所述最佳质量信号的天线元件连接到所述接收器一段持续时间, 比所述测试周期的持续时间长得多,直到执行下一个测试周期。
