According to one embodiment, a first capacitive element may be provided and associated with a surface where a fouling layer is to be detected. A second capacitive element may also be provided, and a capacitance between the first and second capacitive elements may be used to detect formation of the fouling layer. According to another embodiment, a thermal device is provided proximate to a surface where a fouling layer is to be detected. A detector (e.g., a thermometer or vibration detector) may detect a condition associated with the surface, and formation of the fouling layer may be determined based at least in part on the condition.

Early fouling detection

According to some embodiments, an apparatus includes a substrate that defines a plane. The apparatus also includes a first conducting plate that is substantially normal to the substrate and a second conducting plate that is (i) substantially normal to the substrate and (ii) deformable in response to a pressure.

Microelectromechanical system pressure sensor and method for making and using

A system for monitoring and controlling activation of a warning system includes a sensor module locally coupled to the warning system for sensing and controlling a flashing light of the warning system, a transceiver responsive to a microcontroller, and a power line interface for interfacing between the transceiver and the power line servicing the warning system. The sensor module includes a sensor arranged for sensing the flashing light, the microcontroller coupled to the sensor, and a power supply for providing power to the sensor module.

Method and apparatus for monitoring and controlling warning systems

A system for modulating a carrier frequency to support nondestructive bitwise arbitration of a communication medium. The system comprises a first sensor module coupled to a power supply line via a first power line coupling circuit. The first sensor module comprises a first micro-controller and a first transceiver. The first transceiver includes a first transmitter for converting a digital signal received from the first micro-controller into a first analog signal for transmission over the power supply line. The first transmitter includes a first oscillator operating within an allowable frequency deviation to provide a first predetermined onset phase. The system further comprises a second sensor module coupled to the power supply line via a second power line coupling circuit. The second sensor module comprises a second micro-controller and a second transceiver. The second transceiver includes a second transmitter for converting a digital signal received from the second micro-controller into a second analog signal for transmission over the power supply line. The second transmitter includes a second oscillator operating within the allowable frequency deviation to provide a second predetermined onset phase. The second analog signal is different from the first analog signal and the second predetermined onset phase is different from the first predetermined onset phase. The difference between the first predetermined onset phase and the second predetermined onset phase is within a limit.
