A processing system includes processors and dynamically configurable communication elements (DCCs) coupled together in an interspersed arrangement. A source device may transfer a data item through an intermediate subset of the DCCs to a destination device. The source and destination devices may each correspond to different processors, DCCs, or input/output devices, or mixed combinations of these. In response to detecting a stall after the source device begins transfer of the data item to the destination device and prior to receipt of all of the data item at the destination device, a stalling device is operable to propagate stalling information through one or more of the intermediate subset towards the source device. In response to receiving the stalling information, at least one of the intermediate subset is operable to buffer all or part of the data item.

A system and method for estimating a channel spectrum. The method includes: (a) receiving an input signal from a channel, where the input signal includes one or more major echoes and zero or more minor echoes introduced by the channel; (b) identifying the one or more major echoes present in the input signal; (c) identifying the minor echoes from a filtered autocorrelation function of the input signal in response to a determination that there is only one major echo; (d) identifying the minor echoes from a filtered power spectrum of the input signal in response to a determination that there is more than one major echo; (e) computing a channel spectrum estimate from the major echoes and minor echoes; where the channel spectrum estimate is usable to remove at least a portion of the one or more major echoes and one or more minor echoes from the input signal.

Frequency domain equalization of communication signals

Systems and methods for detecting corrosion are provided. In one embodiment, a luminescent material coupled to a cladding of an optical fiber may be altered when exposed to corrosion. The backscatter emission of the luminescent material, which includes the altered optical properties, may be used to determine properties of the corrosion including, for example, thickness, or location of the corrosion.

The present invention additionally comprises a method and apparatus for generating and mixing signals for frequency-domain lifetime and spectral fluorometry. The present invention comprises a plurality of signal generators that generate a plurality of signals where the signal generators modulate the amplitude and/or the frequency of the signals. The present invention uses one of these signals to drive an excitation signal that the present invention then directs and transmits at a target mixture, which absorbs the energy from the excitation signal. The property of fluorescence causes the target mixture to emit an emitted signal that the present invention detects with a signal detector. The present invention uses a plurality of mixers to produce a processor reference signal and a data signal. The present invention then uses a processor to compare the processor reference signal with the data signal by analyzing the differences in the phase and the differences in the amplitude between the two signals. The processor then extracts the fluorescence lifetime and fluorescence spectrum of the emitted signal from the phase and amplitude information using a chemometric analysis.

Signal generation and mixing electronics for frequency-domain lifetime and spectral fluorometry

A method and system for measuring optical scattering characteristics includes coupling a continuous wave laser excitation signal to an optical fiber. Radiation backscattered by the optical fiber in response to the coupled excitation signal is detected to produce a backscattered radiation signal. The backscattered radiation signal is mixed with the excitation signal to produce a mixed signal. The mixed signal is filtered to reduce the magnitude of frequencies other than conjugate mixing frequencies relative to the conjugate mixing frequencies. The filtered signal is digitized and the magnitude of backscattered radiation from a specific portion of the fiber is calculated based on the digitized signal. The temperature of a specific portion of the fiber can be determined from the magnitude of the backscattered radiation.
