    • A method for performing Time Difference Of Arrival (TDOA) that eliminates the need for a common time base or clock calibration and a system for implementing the method. The method relies on a packet transmitted from a reference wireless device (first wireless device) with a known propagation delay between the first wireless device and a second device, which serves as a common reference point for all TDOA estimates. When a packet is received from a wireless device by the first wireless device and the second wireless device, the time difference of arrival is computed based on when the signal was received by the first device and the second device, using the known propagation delay to compensate for differences in clocks and frequencies between the first wireless device and the second wireless device.
    • 用于执行到达时差(TDOA)的方法,其消除了对公共时基或时钟校准的需要以及用于实现该方法的系统。 该方法依赖于从第一无线设备和第二设备之间具有已知传播延迟的参考无线设备(第一无线设备)发送的分组,其用作所有TDOA估计的公共参考点。 当通过第一无线设备和第二无线设备从无线设备接收到分组时,基于第一设备和第二设备何时接收到信号,使用已知的传播延迟来补偿到达时间差 用于第一无线设备和第二无线设备之间的时钟和频率的差异。

    • An integrated process and system for producing electricity for stationary purposes or for electric-powered vehicle using any of multiple hydrocarbon input fuels, a fuel cell, and a thermoelectric reformer that allows quick response to transient loads. Optional high-temperature and low-temperature water-gas shift reactors are used to convert carbon monoxide to carbon dioxide in the reformate stream; a hydrogen separator is used to remove carbon dioxide, carbon monoxide, and trace hydrocarbons; and a condenser is used to remove moisture from the reformate stream. Hydrogen gas not consumed in the fuel cell is stored or recycled for subsequent input to the fuel cell. H2O produced in the fuel cell is recycled for use in the reformer and water-gas shift reactors and is heated with waste heat from the fuel cell and carbon dioxide, carbon monoxide, and hydrocarbons from the hydrogen separator. A mixer is used to vaporize the input fuel prior to entering the thermoelectric reformer. Some of the electricity produced in the fuel cell is used for powering the thermoelectric reformer and is also stored for subsequent startup and peak load purposes.
    • 用于固定目的生产电力的集成过程和系统,或者使用任何多种烃输入燃料,燃料电池和热电重整器的电动车辆,其允许对瞬态负载的快速响应。 使用可选的高温和低温水煤气变换反应器将一氧化碳转化为重整产品流中的二氧化碳; 使用氢气分离器去除二氧化碳,一氧化碳和微量碳氢化合物; 并且使用冷凝器从重整产品流中除去水分。 在燃料电池中未消耗的氢气被储存或再循环用于随后输入燃料电池。 在燃料电池中产生的H 2 O再循环用于重整器和水煤气变换反应器中,并且用来自燃料电池的废热和来自氢气分离器的二氧化碳,一氧化碳和烃加热。 在进入热电重整器之前,使用混合器来蒸发输入燃料。 在燃料电池中产生的一些电力用于为热电重整器供电,并且还存储用于随后的启动和峰值负载目的。
