    • A multifunctional multichip system can operate in a passive mode by using at least one antenna to receive electromagnetic energy and using that energy to perform system functions. The system includes a sensor, an impedance matching circuit and an RFID module. The sensor produces a sensor signal containing a measurement. The RFID can produce an identification signal containing identification information. Alternatively, the RFID chip can be used in an addressing mode wherein the system only produces a signal in response to an addressing signal containing addressing information. The addressing signal is received from the electromagnetic field. In either mode, the sensor signal is coupled from the antenna into the electromagnetic field from which a receiver can obtain it. The signal can contain the identification information as well as the measurement. A matching network minimizes the effects of impedance mismatches between the system elements.

    • A fluid pumping system that includes a motor and a pump, wherein an output shaft of the motor is directly coupled to an input shaft of the pump. This coupling between the output shaft of the motor and the input shaft of the pump may be the primary mechanism for coupling the motor to the pump. Such a configuration may be called a “floating pump mount”, because the pump is primarily coupled to the motor via the shaft connection. As a result of this connection, the output shaft of the motor may be naturally “aligned” with the input shaft of the pump. To help prevent the pump from freely rotating with the output shaft of the motor during operation, a rotational stop mechanism may be provided. The rotational stop mechanism may include at least one resilient member for absorbing or substantially absorbing at least some of any relative movement between the pump and the motor.
    • 一种包括马达和泵的流体泵送系统,其中马达的输出轴直接联接到泵的输入轴。 马达的输出轴与泵的输入轴之间的这种耦合可以是用于将马达耦合到泵的主要机构。 这种配置可以被称为“浮动泵安装座”,因为泵通过轴连接主要耦合到电动机。 作为这种连接的结果,马达的输出轴可以与泵的输入轴自然地“对准”。 为了在操作期间防止泵与电动机的输出轴自由旋转,可以设置旋转停止机构。 旋转停止机构可以包括至少一个弹性构件,用于吸收或基本上吸收泵和马达之间的任何相对运动中的至少一些。

    • Sensor systems and methods are disclosed herein, including a sensor chip, upon which at least two surface acoustic wave (SAW) sensing elements are centrally located on a first side (e.g., front side) of the sensor chip. The SAW sensing elements occupy a common area on the first side of the sensor chip. An etched diaphragm is located centrally on the second side (i.e., back side) of the sensor chip opposite the first side in association with the two SAW sensing elements in order to concentrate the mechanical strain of the sensor system or sensor device in the etched diagram, thereby providing high strength, high sensitivity and ease of manufacturing thereof.

    • Disposable pressure sensor methods and systems are disclosed. A substrate can be provided, along with a capacitor and an inductor fixed to the substrate to form a pressure sensor thereof. In a variable L configuration, the inductor can be configured to comprise an inductor surface and a diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the inductor surface, thereby resulting in an increase in the inductance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. In a variable C configuration, the capacitor can be configured to comprise one electrode on the surface and one on the diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the capacitor surface, thereby resulting in an increase in the capacitance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. Such increase and/or decrease data are detectable by external interrogation.
