  • Publication number: 20040203928
    Abstract: Systems and methods for binning spatially relevant data and corresponding geographical location information are disclosed. In a preferred embodiment, the system comprises at least one transmission device operable to transmit spatially relevant data and corresponding location information for the data to a server. Preferably, an instruction set is executable by a processor-based device (e.g., the transmission device or the server) for generating a single spatial index value for the location information. Accordingly, the spatially relevant data may be indexed using its corresponding spatial index value.

  • Publication number: 20040149832
    Abstract: This invention is an air direction unit that accepts and holds various types of media in frames that can be wetted with water while passing air through the media for the purpose of introducing water vapor into the air stream. This unit can force the entire air stream through the media and is equipped with control dampers that allow bypass of the media to allow direct control of water vapor capacity. This unit is scalable to encompass a range of air stream capacities.

  • Patent number: 5162723
    Abstract: A sampling signal analyzer in which the frequency of an input signal to be measured is initially ascertained, an appropriate sampling frequency is then determined, data needed to reconstruct the wave form of the input signal is acquired, and the input signal wave shape is reconstructed with a calibrated time axis and preferably displayed. The sampling signal analyzer synthesizes a sampler drive signal to enable continuous sampling of the input signal and therefore has the advantage over known data sampling signal measurement instruments that it is not triggered directly in response to the level of the input signal to be measured. Instead, sample timing is based on numerical analysis of the intermediate frequency (IF) signal produced by the sampler. The IF frequency can be an arbitrarily low frequency, which allows digitizing and digital signal processing for aligning measurement data from sweep to sweep with precision.

  • Patent number: 4928251
    Abstract: Representations of signal edges of a repetitive signal are sampled without triggering, then sorted out based on frequency and sequence and then superimposed along a common time base of one period in order to reconstruct a signal. In a specific embodiment of a method according to the invention, a string of samples of a repetitive, input signal with high frequency components is captured without triggering with relatively low time resolution to determine an approximate waveform from the low resolution samples, then digital signal processing techniques in the form of a fast Fourier transform are applied to a reconstructed time record of the input signal to obtain an accurate frequency for each signal component, and finally the sampled waveform is reconstructed by overlaying sampled components with reference to a common time or phase reference. The FFT is employed to determine the frequency of each signal component very accurately.
