摘要:
A system and method for monitoring degradation of a device having a metal layer and a composite layer, such as a vehicle-mounted boom arm. The system can include a collar mounted on an outer surface of the device, a radiography device movably coupled to the collar, and a monitor. The radiography device can include a source of radiography signals positioned to direct radiography signals through at least a portion of the device and a detector to detect radiography signals that have passed through the device. The monitor can be connected to the detector to display an image of the device generated from the detected radiography signals. Anomalies in the device image can represent degradation in the device.

Methods and devices for correcting sensing device signals, e.g., for point of care immunoassay devices. In one embodiment, the invention is to a method of correcting a signal in a sensing device, comprising the steps of: providing a sensing device comprising a sensor, a first electrical pad, a second electrical pad, and a continuous polymer layer contacting at least a portion of the first and second electrical pads; applying a potential across the first and second electrical pads; measuring an electrical property associated with the continuous polymer layer; determining a correction factor associated with the measured electrical property; and applying the correction factor to a signal generated by the sensor to produce a corrected signal.
摘要:
A multi-sensor apparatus for monitoring a fluid is described. The apparatus includes a plurality of sensors, wherein each sensor is configured to be exposed to a fluid, and includes at least one membrane that covers the plurality of sensors. A mechanical member or a heating element can be used to selectively expose a particular sensor to the fluid leaving another of the sensors unexposed to the fluid.

Various sensor unit configurations are disclosed within the context of a fluid quality monitoring system. The distribution of sensor units can be accomplished using existing product distribution channels to sell, distribute and install sensor units so that a fluid distribution monitoring system can be established at relatively low cost, on a wider basis, and by locating sensor units at the most desirable location from problem detection standpoint, the location of the end user.
