    • A pair of mating connectors includes a receptacle having an insulative housing and at least one conductive receptacle contact with a pair of spaced walls forming a plug contact receiving space. The plug connector has an insulative housing and at least one conductive contact having a pair of spaced walls which converge to form a projection engageable in the plug receiving space of the receptacle contact. In each case, the spaced walls are joined by a bridging structure that unites the walls. The plug and receptacle contacts are retained in the respective housings by engagement of opposed lateral edge portions of the contacts with the housings in a manner to enhance heat dissipation by convection by maintaining substantial portions of the contacts spaced from the housing walls and from each other. The bridging structure may include a retention element for engaging respective connector housings to retain the contact in the housings. The open structure of both the receptacle and plug contacts enhances heat dissipation and allows flexibility in achieving desired contact normal forces. The contact construction is especially useful for electronic power connectors.
    • 一对配合连接器包括具有绝缘外壳的插座和至少一个与一对间隔开的壁形成插头接触空间的导电插座触点。 插头连接器具有绝缘壳体和至少一个导电触头,该导电触头具有一对间隔开的壁,其汇合以形成可接合在插座触头的插头接收空间中的突起。 在每种情况下,间隔开的壁通过使壁连接的桥接结构连接。 插头和插座触头通过将触头的相对的侧边缘部分与壳体接合,以通过将接触件的大部分保持与壳体壁彼此隔开的方式通过对流来增强散热性而保持在相应的壳体中。 桥接结构可以包括用于接合相应的连接器壳体以将接触保持在壳体中的保持元件。 插座和插头触点的开放结构增强了散热性,并且允许实现期望的接触法向力的灵活性。 接触结构对于电子电源连接器特别有用。

    • A method of performing a frequency correction of a radio module. Multiple samples of frequency data during a quiescent portion of the base station transmission is taken to estimate the amount of frequency correction needed. An embodiment applies the frequency data to a median filter to eliminate invalid data. Next, a new reference frequency is applied to a radio transceiver in the radio module to provide the frequency correction. If the frequency was corrected by greater than a pre-determined amount, the process performs a large shift frequency correction, including verifying that the first frequency correction was satisfactory and verifying that the radio transceiver is able to receive data after the frequency correction has been performed. If the frequency was corrected by smaller than a pre-determined amount, the process performs a small shift frequency correction, including updating a total of all frequency corrections made since a stored reference frequency was updated.
    • 执行无线电模块的频率校正的方法。 采用在基站传输的静止部分期间的频率数据的多个样本来估计所需的频率校正量。 一个实施例将频率数据应用于中值滤波器以消除无效数据。 接下来,将新的参考频率应用于无线电模块中的无线电收发器以提供频率校正。 如果频率被校正大于预定量,则该处理执行大的移位频率校正,包括验证第一频率校正是令人满意的并且验证无线电收发机能够在执行频率校正之后接收数据 。 如果频率被校正小于预定量,则该处理执行小的移位频率校正,包括更新从存储的参考频率更新以来所做的所有频率校正的总和。

    • The removable fireplace cleanout facilitates the chore of cleaning ash and/or other residue from a fireplace. The cleanout device is a relatively wide, low pan or tray configured for placement within a fireplace hearth. Wheels and/or other rolling supports extend beneath the device to facilitate its installation in and removal from the fireplace hearth. One wall of the device includes a dump door, with the weighted door being held closed by gravity until the unit is tilted to dump ash and residue therein. Fillets may be provided to preclude trapping of ash in the corners of the device. An integral grate may be permanently installed atop the floor of the device, thereby precluding need for grate removal and soiling of the area where the grate is placed during conventional fireplace cleanout.
    • 可拆卸的壁炉清洁方便了清洁灰和/或壁炉其他残留物的烦恼。 清洁装置是相对较宽的低盘或托盘,其配置用于放置在壁炉炉床内。 车轮和/或其他滚动支撑件在装置下方延伸,以便于其安装在壁炉炉床中并从壁炉炉床移除。 设备的一个墙壁包括倾倒门,重物门被重力保持关闭,直到该单元倾斜以将灰渣和残渣倒出来。 可以提供圆角以防止灰尘在装置的角落中被捕获。 整体式格栅可以永久性地安装在设备的地板上,从而排除了在常规壁炉清理期间放置炉排的区域的炉排去除和污染的需要。
