    • An improved bio-medical telemetry apparatus for programming an implanted medical device includes a large substantially planar and concentrically wound first telemetry coil. The coil is disposed inside a thin flexible housing including layers of insulative materials to prevent electrical contact between loops of the first telemetry coil and to hold the first telemetry coil formed shape in place. The apparatus further includes a communication lead coupled to the first telemetry coil for communicating with a medical device programmer. During a telemetry session the first telemetry coil including the flexible housing is disposed at a posterior location of the torso and an implanted medical device disposed subcutaneously on an anterior location of the torso. During programming the first telemetry coil is inductively coupled to the implanted medical device for wireless data communication with the implanted medical device. The large, substantially planar design of the first telemetry coil permits more even and large flux paths, which allow for less precise positioning of the apparatus with respect to the implanted medical device. Also, the flexible housing conforms to irregular surface of patient's and supporting furnishing providing comfort to patients lying upon the first telemetry coil during telemetry sessions.
    • 用于编程植入式医疗装置的改进的生物医学遥测装置包括大的基本平面和同心缠绕的第一遥测线圈。 线圈设置在包括绝缘材料层的薄柔性壳体内,以防止第一遥测线圈的环路之间的电接触并且将第一遥测线圈形成的形状保持在适当位置。 该装置还包括耦合到第一遥测线圈的通信引线,用于与医疗装置编程器通信。 在遥测会话期间,包括柔性壳体的第一遥测线圈设置在躯干的后部位置处,并且植入医疗装置皮下设置在躯干的前部位置。 在编程期间,第一遥测线圈感应耦合到植入的医疗装置,用于与植入的医疗装置的无线数据通信。 第一遥测线圈的大的基本上平面的设计允许更大的平均和大的通量路径,这允许装置相对于植入的医疗装置的精确定位较少。 此外,柔性壳体符合患者的不规则表面和支撑装置,为在遥测期间躺在第一遥测线圈上的患者提供舒适感。

    • An improved ammunition data transmission system includes alternately applied parallel sources of high frequency of alternating current (AC) voltage and direct current (DC) voltage. The high frequency AC voltage is applied first to provide updated data and to activate the electronic control package for the round in the projectile. the DC voltage then activates the electric primer system for igniting the propellant charge to fire the round. Both the electronics control package and the electric primer system are connected in parallel with the source of AC voltage and, in the preferred embodiment, the parallel connected circuitry contains a capacitor to prevent DC voltage from reaching the electronics control package and an inductor for preventing AC voltage from reaching the electric primer system.
    • 改进的弹药数据传输系统包括交替施加的交流(AC)电压和直流(DC)电压的高频并联源。 首先施加高频交流电压以提供更新的数据,并激活用于抛射体的圆的电子控制包。 直流电压然后激活电引燃系统,用于点燃推进剂装药以射击。 电子控制封装和电底漆系统都与AC电压源并联连接,在优选实施例中,并联电路包含用于防止直流电压到达电子控制封装的电容器和用于防止AC的电感器 电压达到电动底漆系统。
