    • A system, computer-readable medium, and method of operating a dual-mode 4G and 3G communications device capable of operating in a 3G mode or a 4G mode includes receiving a first base station (BS) location message from the BS and storing the received location as a current BS location. The BS location is compared to stored region coordinates for the different regions, and the comparison is used to determine a particular region in which the dual-mode device is currently located. Analysis determines whether a 4G market is located within the particular region. If no 4G markets are located, the dual-mode device is operated in the 3G mode. If one or more 4G markets are located within the particular region, a determination is made as to whether the BS location is within a 4G market and, if so, the dual-mode device is placed in a 4G mode of operation. Battery power is conserved by avoiding 4G transmission when 4G service is not available at the current BS location. The 4G device may operate either as a WiMAX device and/or as an LTE device.
    • 能够以3G模式或4G模式操作的双模式4G和3G通信设备的系统,计算机可读介质和方法包括从BS接收第一基站(BS)定位消息并存储所接收的 位置作为当前的BS位置。 将BS位置与不同区域的存储区域坐标进行比较,并且使用比较来确定双模设备当前所在的特定区域。 分析决定了4G市场是否位于特定地区。 如果没有4G市场,则双模设备以3G模式运行。 如果一个或多个4G市场位于特定区域内,则确定BS位置是否在4G市场内,如果是,则将双模设备置于4G操作模式。 当4G服务在当前的BS位置不可用时,通过避免4G传输来节省电力。 4G设备可以作为WiMAX设备和/或作为LTE设备操作。

    • A wave energy converter (WEC) includes a float and a spar for guiding the up and down movement of the float in response to the waves. A power take off (PTO) device coupled between the float and the spar and mounted within one of the float and spar such that the PTO includes apparatus responsive to the mechanical interaction of the float with the portion of the spar in proximity to the float for converting their relative motion into useful energy. In one embodiment the PTO includes a linear rack extending along an external portion of the spar and a linear to rotary converter, mounted within the float, including a double sided toothed belt for engaging the rack and causing rotation of the rotary converter to drive an electric generator. In another embodiment the PTO includes tires mounted within the float which rotate as the float moves up and down. In another embodiment the PTO includes a rack and pinion arrangement with one of them connected to the spar and the other mounted in the float.
    • 波浪能转换器(WEC)包括浮子和翼梁,用于响应于波浪来引导浮子的上下运动。 耦合在浮子和翼梁之间并且安装在浮子和翼梁之一内的动力输出(PTO)装置,使得PTO包括响应于浮子与靠近浮子的翼梁的部分的机械相互作用的装置, 将其相对运动转化为有用能量。 在一个实施例中,PTO包括沿着翼梁的外部部分延伸的线性齿条和安装在浮子内的线性到旋转转换器,包括用于接合齿条的双面齿形带,并引起旋转转换器的旋转以驱动电动 发电机。 在另一个实施例中,PTO包括安装在浮子内的轮胎,其随着浮子上下移动而旋转。 在另一个实施例中,PTO包括齿条和小齿轮装置,其中一个连接到翼梁,另一个安装在浮子中。
