    • A bidirectional power converter circuit is controlled via a hysteresis loop such that the bidirectional power converter circuit can compensate for variations and even changes in transmit and receive coil locations without damaging components of the system. Because the bidirectional power converter is capable of both transmitting and receiving power (at different times), one circuit and board may be used as the main component in multiple wireless power converter designs. A first bidirectional power converter is employed in a sealed battery unit having no external electrical contacts. A second bidirectional power converter is employed in a corresponding cart bidirectional power converter assembly. The battery unit and the cart bidirectional power converter assembly cooperate to wirelessly transmit power from the battery unit to a load of the cart bidirectional power converter assembly and from a power source to the battery unit via the cart bidirectional power converter assembly.
    • 双向功率转换器电路通过磁滞回线来控制,使得双向功率转换器电路可以补偿发射和接收线圈位置的变化甚至变化,而不损坏系统的部件。 由于双向功率转换器能够发送和接收功率(在不同时间),所以可以在多个无线功率转换器设计中使用一个电路和电路板作为主要组件。 在没有外部电触点的密封电池单元中采用第一双向功率转换器。 第二双向功率转换器用于相应的小车双向功率转换器组件。 电池单元和小车双向功率转换器组件协作,以将电池从电池单元无线传输到购物车双向功率转换器组件的负载,并且经由购物车双向功率转换器组件从电源向电池单元进行无线传输。

    • A method and apparatus for scanning, by an asset tag manager during a scanning window, for wireless broadcasts from beacon devices. The method further filters the wireless broadcasts to generate a subset of the wireless broadcasts. The method continues by identifying, within the subset of the wireless broadcasts, a first wireless broadcast with a first data packet in view of an indication that a first beacon device is within a specified distance from the asset tag manager. The method proceeds by parsing the first data packet to locate a first beacon identifier associated with a first beacon device. The method also creates a second data packet with the first beacon identifier and an asset tag identifier associated with the asset. The method transmits a second wireless broadcast comprising the second data packet, the second wireless broadcast to be received by a hub.
    • 一种用于在扫描窗口期间由资产标签管理器扫描来自信标设备的无线广播的方法和装置。 该方法进一步过滤无线广播以生成无线广播的子集。 考虑到第一信标设备与资产标签管理器在指定距离内的指示,继续在无线广播的子集内识别具有第一数据分组的第一无线广播。 该方法通过解析第一数据分组来定位与第一信标设备相关联的第一信标标识符。 该方法还创建具有与资产相关联的第一信标标识符和资产标签标识符的第二数据分组。 该方法发送包括第二数据分组的第二无线广播,由集线器接收的第二无线广播。
