    • A panel having a magnetic mounting that utilizes a plurality of magnets in a magnet structure that allows high magnetic force when the panel is installed and the magnet structure is aligned while permitting removal using relatively light force applied to misalign the magnet structure to allow removal. In one embodiment, the magnet structure can provide precision positioning of the panel to a position on the order of the width of a single component magnet of the magnet structure. In another embodiment, the magnet structure may be misaligned for removal by a rotation of the magnet structure. In a further embodiment, the misalignment may be achieved by a lateral shift of the magnet structure. The invention may be adapted to a wide variety of panels including but not limited to doors, window coverings, storm coverings, seasonal covering panels, baby gates, white boards, and green house panels.
    • 一种具有磁性安装件的面板,其利用磁体结构中的多个磁体,当安装面板时允许高磁力并且磁体结构对准,同时允许使用相对较轻的力去除磁体结构以使其移除以取消对准。 在一个实施例中,磁体结构可以将面板精确地定位到磁体结构的单个部件磁体宽度的位置上。 在另一个实施例中,磁体结构可能不对准,以通过磁体结构的旋转来移除。 在另一实施例中,可以通过磁体结构的横向偏移来实现未对准。 本发明可以适用于各种面板,包括但不限于门,窗帘,风暴覆盖物,季节性覆盖板,婴儿门,白板和温室板。

    • Time is transferred from an ultra wideband (UWB) transmitter to UWB receiver by transmitting a signal structure having an associated timing reference point together with a time value for the timing reference point. The UWB receiver receives the timing signal structure by synchronizing a receiver time base to the signal structure, demodulating the time value information, and using the demodulated time value information to set a receiver clock value. Propagation delay information is used to adjust the receiver clock value by advancing the receiver clock value to account for the propagation delay. In one embodiment, propagation delay is determined from a known distance between the transmitter and receiver. In another embodiment, the transmitter and receiver are part of a two-way link wherein propagation delay is measured by round trip timing measurements.
    • 通过发送具有相关联的定时参考点的信号结构以及定时参考点的时间值,将时间从超宽带(UWB)发射机传送到UWB接收机。 UWB接收机通过将接收机时基同步到信号结构,解调时间值信息,并使用解调时间值信息来设置接收机时钟值来接收定时信号结构。 传播延迟信息用于通过提高接收机时钟值来考虑传播延迟来调整接收机时钟值。 在一个实施例中,从发射机和接收机之间的已知距离确定传播延迟。 在另一个实施例中,发射机和接收机是双向链路的一部分,其中通过往返定时测量来测量传播延迟。
