Abstract: A physically compact, wideband signal activity identification, demodulation and characterization, and direction finding device incorporates multiple and cascadable digital signal processing modules operating in asynchronous real time. The digital signal processing modules include a device for data buffering, a device for digital signal processing (DSP), and a device for high-speed data routing. The module device for data buffering is composed of, among other memory devices, a First In Tap Out (FITO) data buffer that may be accessed at any point for delay or faster than real time resynchronization by the DSP module device. The module device for digital signal processing function incorporates a general purpose digital processor for respective module calculation of overlapped hyperchannelization Fast Fourier Transforms (FFT).

Abstract: A sundial gnomon including a first surface having a plurality of parallel first surface apertures transmissive to light and through which a plurality of sunbeams pass, and a second surface having a plurality of second surface segment apertures for regulating the passage of sunbeams passing through the plurality of first surface apertures. The plurality of second surface segment apertures are arranged in a plurality of stencil patterns, each stencil pattern including a plurality of second surface segment apertures. The plurality of second surface segment apertures are configured to cause sunbeams passing through the plurality of first surface apertures to be incident upon second surface segment apertures of only one stencil pattern at a given time. Thus, sunbeams passing through the two surfaces will display the hour of the day. Preferably, the gnomon includes a second set of surfaces having apertures therein through which sunbeams pass to respectively display portions of an hour such as 10 minute intervals.

Abstract: A computer implemented method for providing a diagnosis for automotive engine malfunctions using collected vehicle emissions data. The concentration levels of gases within exhaust emitted from a vehicle engine being determined and compared to a plurality of predetermined concentration level data sets stored in a database to find a matching data set. Each predetermined concentration level data set having corresponding engine diagnosis data for identifying engine malfunction. The engine diagnosis and concentration level data being printed on a testing diagnosis form to be filled out by mechanics upon repair of the malfunctioning engine. Upon return of a previously tested vehicle that has been repaired, the same test is performed on the vehicle and the newly collected concentration level data is compared with the prior failing concentration level data to determine the accuracy of the repair performed.

Abstract: Fabric pieces or panels are releasably mounted in a unique materials handling clip or cartridge to facilitate handling, identification, storage, transportation, and registration during subsequent sewing operations. The clips are mechanically assembled onto a magazine where both the clips and fabric panels are maintained in spaced relation to each other. A plurality of magazines are mounted on a loader/feeder apparatus which enables the clips to be automatically and sequentially unloaded and fed to a subsequent processing operation, then reloaded into the magazine. The clips permit easy handling and automatic registration of the separate fabric pieces into sewing fixtures for automated sewing and/or assembly operations while maintaining a prescribed sequence.
