    摘要: Spectroscopic measurements of stable isotopes are performed using a tunable lead salt diode laser. The design of the system is based upon the optimization of isotopic spectral lines from two different path lengths in an absorption cell using a single gaseous sample. A short path cell to measure the more abundant species and a long path cell to measure the less abundant species are used. A micrometer adjustment of a path length is used for equalizing spectral line intensities to obtain a measure of isotope enrichment or of absolute isotopic concentration.

    摘要: A method is provided for precisely and concurrently measuring dynamic engine oil consumption and fuel consumption within an internal combustion engine on a real-time basis. Nonradioactive organo- bromine or chlorine compounds are added to the oil in small amounts in their natural isotopic abundance or enriched. Upon complete combustion, the bromine or chlorine is converted into hydrogen bromide (HBr) or hydrogen chloride (HCl), respectively. A tunable diode laser spectrometer is used to determine the trace amounts of the resultant HBr or HCl in the exhaust gases, which continuously flows through a sample cell by the use of a sample line that allows the unimpeded transport of samples, reduces the pressure of the exhaust gas and maintains it at a suitable level for analysis, and prevents the condensation of water vapor in the exhaust gas so as to prevent the dissolution of the tracer compounds in the water condensate.

    摘要: A method is provided for precisely and concurrently measuring dynamic engine oil consumption and fuel consumption within an internal combustion engine in an automotive environment on a real time basis. Nonradioactive tracer compounds, such as bromine or chlorine in the form of organic bromo- or chloro-compounds are added to the engine oil in small amounts. Upon complete combustion, the bromine or chlorine is converted into either hydrogen bromide or hydrogen chloride. A sample of the exhaust gases generated by the internal combustion engine and comprising the hydrogen bromide or hydrogen chloride is collected and maintained at a pressure where distinction between an absorption line of the tracer specie and the absorption lines of a related isotopic species is discernible. Monochromatic radiation is then transmitted through the gaseous sample at the frequency of an absorption line particular to the tracer specie. Because of the high spectral power density and spectral resolution of the preferred tunable diode lasers, tunable diode laser spectroscopy may be used to measure the amount of tracer isotope within the resultant HCl or HBr gases in the exhaust gases. Corresponding fuel consumption may also be determined from the CO.sub.2 in the exhaust gases by similar methods.

    摘要: Aspects for providing tunable parameters to control distribution in a digital media distributor system are described. A digital media distributor (DMD) with tunable control of digital media data transmission aspect includes a distribution network, a central site system, and a plurality of remote site systems. The central site system utilizes a plurality of designated control parameters, including uplink parameters, scheduler parameters, and storage parameters, for controlling distribution of digital media data. The plurality of remote site servers receive digital media data transmissions from the central site server via the distribution network according to the designated control parameters.

    摘要: A multimedia search and indexing system automatically selects scenes or events of interest from any media, i.e., video, film, sound for replay, in whole or in part, in other contexts. The entire audio track of a recorded event in video, film, sound, etc., is analyzed to determine audio levels within a set of frequency ranges of interest. Audio clip levels within the selected frequency ranges are chosen as audio cues representative of events of interest in the track. The selection criteria are applied to the audio track of the recorded event. An Edit Decision List (EDL) is generated from the analysis of the audio track. The list is representative of scenes or sounds of interest as clips for reuse. The clips are reviewed and accepted or rejected for reuse. Once selected, the clips are edited using industry standard audio and video editing techniques.

    摘要: A simplified TV viewer response system coupled to a telephone system enables a viewer/subscriber to respond to television displays by dialing a special code less than six digits. The code is routed to an enhanced services server. The server captures the dial string including the caller ID, checks the caller ID against a subscriber/viewer profile and maps the caller ID to the cable company providing service to the viewer/subscriber. The server delivers the response to the cable television company which processes the response according to the selected items or choices in the TV screen. Several special dialing codes of limited digits expedite viewer/subscriber selections. Each code includes a special character to route the dialing string to the server. The system provides sound recognition of viewer/subscriber selections.

    摘要: A multi-media search and indexing system for automatic selection of scenes or sounds recorded in media for replay in other context by analyzing the media for a set of frequency ranges of interest for replay. The media is analyzed to select desired frequency ranges of interest within the media, the selected frequency ranges being indicative of a scene or sound of interest. The granularity or length of the selected frequency ranges is selected for analysis. A number of analysis intervals are determined in the selected frequency ranges. The media is filtered for the selected frequency ranges and the audio level is measured for each interval. An audio clip level is established for each frequency range as indicative of a scene or sound of interest. The interval frequency range and audio level are recorded for subsequent replay.
