    • The present invention relates to a wireless communication device and a method for identifying a container for containing contents such as solid, liquid, or gaseous materials. The device includes a wireless communication device for transmitting information regarding the container. A valve assembly is positioned over an opening in the container for controlling the flow of contents from the container. The wireless communication device is mounted within the valve assembly, and preferably within the ball. The wireless communication device communicates information to an interrogation reader. The temperature associated with the container and/or its contents may be determined by various techniques including thermal contact between the temperature sensor and the container, measuring the discharge rate in a discharge capacitor associated with the wireless communication device, and determining the maximum energy absorption frequency of the wireless communication device. The liquid level of the container may be determined by employing liquid level sensor techniques.

    • A hydrogen storage tank for containing solid-state hydrogen storage media, and method for determining the hydrogen fill level in the tank. The tank has at least one compartment for storing the storage media, passages for transporting hydrogen gas to and from the compartment, and a heat distribution system for establishing a substantially uniform temperature in the storage media. A look-up table is generated for the tank that relates hydrogen pressure changes in the tank versus hydrogen fill levels in the tank as a function of temperature. The tank is filled to full capacity by adsorbing hydrogen on the storage media. Thereafter, hydrogen is released from the storage media for a time period during which there is a substantially constant demand on the tank, the change in pressure of the released hydrogen gas is measured, and the look-up table is applied to determine the hydrogen fill level in the tank.
    • 一种用于容纳固态氢存储介质的储氢罐,以及用于确定罐中氢气填充量的方法。 储罐具有至少一个用于存储存储介质的隔室,用于将氢气输送到隔室的通道和用于在存储介质中建立基本均匀的温度的配热系统。 产生一个查询表,用于将罐中的氢气压力变化与储罐中的氢气填充量作为温度的函数关联。 通过在储存介质上吸附氢气将罐装满容量。 此后,从存储介质中释放氢气一段时间,在该时间段内对罐要求基本上恒定,测量释放氢气的压力变化,并且使用查找表来确定氢气填充 在坦克水平。

    • Methods and systems for controlling processes related to the amount of fluid in a container subjected to externally-excited motions. Fluid level sensor measurements in processing tanks on-board boats are confused by ocean waves and swells. A hydrodynamic model of a fluid in a tank can be constructed using non-linear dynamic model algorithms with inputs such as multi-axis accelerations, fluid viscosity, and apparent level measurements. The model can be used to filter-out boat motion disturbances to obtain a corrected level of the fluid in the tank. The corrected fluid level signal can be further processed using a dynamic model of the tank and associated input and output flow rates in a closed loop observer. The methods and systems are especially advantageous for offshore equipment such as cementing and fracturing ships.
    • 用于控制与经受外部激励运动的容器中的流体量有关的方法和系统。 处理坦克船上的液位传感器测量被海浪和波浪所迷惑。 可以使用具有诸如多轴加速度,流体粘度和表观水平测量等输入的非线性动态模型算法来构建罐中流体的流体动力学模型。 该模型可用于过滤船运动干扰,以获得油箱中液体的校正水平。 可以使用罐的动态模型和闭环观测器中的相关联的输入和输出流速来进一步处理校正的液位信号。 该方法和系统对海上设备如固井和压裂船特别有利。
