A real-time, or synchronous, sensor data acquisition system acquires physical characteristics or properties associated with a structure or physical system using a plurality of sensors coupled in series to a single cable. The sensors may sense vibration, noise, temperature, acceleration, pressure, strain, force, etc. The sensors transmit data along the cable at greater than 100 dB dynamic range, with a bandwidth between about 5 to 20 KHz, and in a digital, single bit wide data stream. The sensors include modulators to code the data signals with distinct codes. A receiver has a demodulator to decode and separate the data signals.

A method for detecting extent of cross-linking of a high impedance polymer material during a pre-cure state, the method including: placing an insulated ground plane adjacent to the polymer material and substantially parallel to a sensor; applying a test signal through a sensor to the material and through a reference resistance; determining a voltage difference between the test signal applied to the material and the reference resistance as the reference voltage; and correlating the voltage difference as a relative indicator of the extent of cross-linking which has occurred within the polymer material. Also disclosed is a device for implementing the subject method.

The present invention is embodied in a method and apparatus for utilizing inherently insulative material, such as the glass and epoxy resins used in construction of printed circuit boards, for construction of components in a time of flight mass spectrometer. By using printed circuit board materials, the present invention can take advantage of fabrication techniques for providing circuit traces on surfaces, from one side to another as a via, or embedded within the printed circuit material so as to be covered except where necessary to be exposed to make contact with other electrical devices. Embedded circuit traces also enable capacitive coupling to AC energy while maintaining electrical and physical isolation. Consequently, the present invention enables both invasive and non-invasive access to pressure and vacuum chambers.

An intensity acoustic calibrator is disclosed including at least two wave guide channels. A speaker adjacent each wave guide channel emits sound to develop a standing wave pattern at the opposing end of the channel. The test microphone is positioned in the calibrator so as to be in acoustic communication with the wave guide channel so that the microphone can be calibrated respective to the standing wave pattern. By having two separate wave guide channels and speakers, the test microphones can be subjected to arbitrary magnitude changes and phase differentials. Additionally, a reference microphone may be positioned adjacent each wave guide channel to monitor the sounds generated by the speakers to ensure that the speakers are emitting sounds at the desired magnitude, phase, etc.
