Abstract:

A system and method for ADSL USB bandwidth negotiation are presented. The system comprises a modem that is configured to transfer data between an ADSL line and a USB bus and that is further configured to receive an ADSL line rate setting, submit an isochronous bandwidth request to a computer, reduce the isochronous bandwidth request in response to the availability of isochronous bandwidth, modify the ADSL line rate setting in response to the availability of isochronous bandwidth, and modify the USB bus transfer mode in response to the availability of isochronous bandwidth. The method comprises steps of receiving an ADSL line rate setting, submitting an isochronous bandwidth request to a computer, reducing the isochronous bandwidth request in response to the availability of isochronous bandwidth, modifying the ADSL line rate setting in response to the availability of isochronous bandwidth, and modifying the USB bus transfer mode of the ADSL USB modem in response to the availability of isochronous bandwidth.

International Classification:

G06F 1/12

US Classification:

713400

Abstract:

Systems and methods for synchronizing a clock at a customer premises equipment (CPE) location with a master clock at a central office (CO) location are described. One embodiment is a method that comprises receiving, by a time-of-day transmission convergence (ToD-TC) module in the CPE, ToD information relating to the master clock. Based on the received information, time stamps are applied to reference data samples. The method further comprises transporting the ToD information by transporting the reference data samples with applied time stamps and utilizing time stamps of the reference data samples to synchronize the CPE clock with the master clock.

US Classification:

524186

Abstract:

This invention is first, a difunctional poly(glycidyl nitrate) oligomer (PGN oligomer), second, nitrated PGN oligomer and third, the use of the nitrated PGN oligomer as a plasticizer, particularly as a plasticizer for binders used in and/or as energetic formulations. Examples of energetic formulations are propellants, pyrotechnics and explosives and other such compositions. More particularly, this invention is a difunctional poly(glycidyl nitrate) oligomer of the formula ##STR1## where n is 0 to 3, having a M. sub. n of from about 304 to about 994. Another embodiment is the nitrated difunctional poly(glycidyl nitrate) oligomer of the formula ##STR2## where n is 0 to 3, having a M. sub. n of from about 394 to about 1084. This invention also comprises a plasticizer for binder compounds, namely, the nitrated PGN oligomer above; preferably the plasticizer above is used wherein the binder compound is used in energetic formulations; and preferably the binder compound is an energetic compound; more preferably the energetic formulation is selected from the group consisting of propellants, pyrotechnics and explosives.

Abstract:

The energetic salts of 3-nitramino-4-nitrofurazan have a desirable combination of desirable properties such as sufficiently high densities, and low or no hydrogen content. The salts are useful as ingredients in various propellant, explosive, gassifier, and pyrotechnic compositions. 3-Nitramino-4-nitrofurazan is itself a useful energetic compound and is also useful in the synthesis of still further energetic compounds.

US Classification:

149 199

Abstract:

Improved thermoplastic elastomer compositions having improved processing and mechanical characteristics without requiring addition of excessive quantities of plasticizer comprise at least one thermoplastic elastomer loaded with a crystalline modifier having a relatively low melting point. The modifier can be liquid at the processing temperature, resulting in increased ease in handling of the product. An exemplary crystallizable modifier is an alkylated pentacycloundecane dimer.

US Classification:

Abstract:

Isotactic poly(glycidyl nitrate) useful in solid propellants is produced by polymerizing chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate. Chiral (R) glycidyl nitrate or its enantiomer is prepared by sequential treatment of chiral (S) glycidyl tosylate or its enantiomer with nitric acid and sodium hydroxide. Chiral (S) glycidyl tosylate or its enantiomer, (R) glycidyl tosylate, can be produced by Sharpless epoxidation of allyl alcohol or by direct tosylation of commercially available chiral glycidol. Likewise, chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate, can be prepared direcly via nitration of (S) or (R) glycidol, respectively.
