    • A method of optimizing log truck productivity utilizing technology allowing the entry of log truck orders from the field. The present invention generally seeks to improve productivity by (1) minimizing the distances log trucks drive with empty loads and (2) improving coordination between groups of log truck drivers and groups of log loaders to allow for more efficient cross-servicing between the parties. Using the load input device, a loader operator in the field enters a “load ticket” that specifies a mill destination, a desired pickup time for the truck to arrive at the logging site and a desired trailer configuration type. This order is transmitted to a server where it is a received into a centralized application or server. A computer running optimization software can match the load with available trucks or trucks about to become available.
    • 一种利用允许从现场进入卡车订单的技术优化日志卡车生产效率的方法。 本发明总体上旨在通过以下方式来提高生产率:(1)尽量减少卡车在空载时驱动的距离;(2)改善日志卡车司机和对数装载机组之间的协调,以允许双方之间更有效的交叉维修。 使用装载输入装置,本领域的装载机操作员输入指定轧机目的地的“装载单”,卡车到达采伐地点的期望取货时间和期望的拖车配置类型。 该命令被发送到服务器,它被接收到集中的应用程序或服务器中。 运行优化软件的计算机可以将货物与可用的卡车或卡车相匹配。

    • A security shield device is provided in two embodiments. One embodiment includes a front cover, a rear base and a connector member connecting the front cover to the rear base. The front cover is mounted to a slidebolt latch for movement between a covered position shielding a padlock shackle coupled to a latch portion of a slidebolt latch and an uncovered position displaced from the latch portion of the slidebolt latch. The rear base mates with the latch portion of the slidebolt latch so as to attach the rear base to the slidebolt latch when the padlock shackle is coupled to the slidebolt latch. The connector member prevents movement of the front cover relative to the slidebolt latch away from the rear base which would expose the shackle of the padlock. The other embodiment includes a front cover, a rear base connected to the front cover, and apertures defined therein aligned with openings in stationary and movable latch portions of a slidebolt latch. The aligned apertures and openings receive a padlock shackle to couple the security shield device and stationary and movable latch portions together with upper edge portions of the front cover and rear base disposed on opposite sides of the latch portions shielding the latch portions of the slidebolt latch and padlock shackle coupled thereto.
    • 在两个实施例中提供安全屏蔽装置。 一个实施例包括前盖,后底座和将前盖连接到后底座的连接器构件。 前盖安装到滑动闩锁上,用于在屏蔽耦合到滑动闩锁闩锁的闩锁部分的挂锁钩环与从滑动闩锁闩锁的闩锁部分偏移的未覆盖位置的覆盖位置之间移动。 后座与滑动闩锁的闩锁部分配合,以便当挂锁钩环联接到滑动闩锁时,将后底座连接到滑动闩锁闩。 连接器构件防止前盖相对于滑杆闩锁远离后底座的移动,这将使挂锁的钩环暴露。 另一个实施例包括前盖,连接到前盖的后基座和限定在其中的孔,其与滑动闩锁的固定和可移动闩锁部分中的开口对准。 对准的孔和开口接收挂锁钩环,以将安全屏蔽装置和固定和可移动的闩锁部分连接在一起,前盖和后基座的上边缘部分布置在闩锁​​部分的相对侧上,从而屏蔽滑动闩锁闩锁的闩锁部分, 挂锁钩环联接到其上。

    • System(s) and method(s) for compensation of propagation delay offsets of wireless signals. Compensation is accomplished through determination of an effective wireless signal propagation delay that accounts for signal path delay and propagation delay over the air. Such determination is based at least in part on statistical analysis of accurate location estimates of reference positions throughout a coverage sector or cell, and location estimates of the reference positions generated through time-of-flight (TOF) measurements of wireless signals. Determination of propagation or signal path delay offset also is attained iteratively based at least in part on reference location estimates and TOF location estimates. High-accuracy location estimates such as those obtained through global navigation satellite systems are employed as reference location estimates. Position of probes or wireless beacons, deployed throughout a sector or cell, also are employed as reference locations. Compensation of propagation delay offset improves accuracy of conventional TOF location estimates and radio network performance.
    • 用于补偿无线信号的传播延迟偏移的系统和方法。 通过确定考虑到空中信号路径延迟和传播延迟的有效无线信号传播延迟来实现补偿。 这种确定至少部分地基于整个覆盖扇区或小区中的参考位置的精确位置估计的统计分析以及通过无线信号的飞行时间(TOF)测量产生的参考位置的位置估计。 至少部分地基于参考位置估计和TOF位置估计,迭代地获得传播或信号路径延迟偏移的确定。 通过全球导航卫星系统获得的高精度位置估计值被用作参考位置估计。 探测器或无线信标的位置,部署在整个扇区或单元中也用作参考位置。 传播延迟偏移的补偿提高了常规TOF位置估计和无线网络性能的准确性。
