Abstract:
A method and system for mutually authenticating a client and a server is provided in accordance with an aspect of the present invention. The method commences with transmitting a token from the server to the client. Thereafter, the method continues with establishing a secure data transfer link between the server and the client. A server certificate is transmitted to the client during the establishment of the secure data transfer link. The method continues with transmitting a response packet to the server, which is validated thereby upon receipt. The system includes a client authentication module that initiates the secure data transfer link and transmits the response packet, and a server authentication module that transmits the token and validates the response packet.
Abstract:
A method and system for secured network access is provided in accordance with the present invention. The method begins with receiving a login request from a client on a router. Thereafter, a certificate transfer instruction for the router to an authentication appliance is generated where the client lacks a copy of a client certificate. The client is authenticated with a challenge-response sequence, the response to which is deliverable through an out-of-band communications channel. Upon authentication, the client certificate and the client private key are transmitted to the client, which are used to authenticate the client to the network.
Abstract:
A method of providing synchronization of the clocks of all of the media gateways of an Ethernet, or equivalent, IP network used in the transmission of audio data between media gateways using a clock provided by the PSTN. The selection of one of the media gateways connected to the PSTN, termed the master CoHub (Central Office Hub), is used as a clock master. This CoHub derives its clock from its TDM-interface's frame-synchronization with the PSTN to which it is connected. Utilizing this gateway-synchronization method, all MG's are synchronized to this PSTN clock-source.

Abstract:
An energy system is formed of a plurality of battery cells, and has an application associated therewith that draws power from the energy system, thereby creating a load profile that is presented to the energy system. As the application is being used, voltage and current measurements are taken at a predetermined rate, and stored in a history table to create a series of time-based measurements. The measurements stored in the history table are then processed to produce an energy spectra and a power spectra corresponding to the load profile presented to the energy system by the application. A charging strategy in accordance with this energy spectra and power spectra is then defined and used to charge the energy system appropriately.
Abstract:
An apparatus and method for consolidating a composite workpiece are provided. The apparatus includes an electromagnetic field generator for inducing a current and thereby heating a susceptor in thermal communication with the workpiece. The workpiece is supported by one or more support tools, each of which transmits the electromagnetic field so that the support tools are not substantially heated by the electromagnetic field. Thus, the time and energy required for heating the workpiece are reduced relative to conventional consolidation techniques.
Abstract:
A process for preparing a compound of formula (I, I) or a tautomeric form thereof or a pharmaceutically acceptable salt thereof or a pharmaceutically acceptable solvate thereof, wherein: J represents O or S; T represents a substituted or unsubstituted aryl group and T1 is O or S; which process comprises reducing a compound of formula (II, II) or a tautomeric form thereof or a salt thereof or a solvate thereof, wherein T and T1 are as defined in relation to formula (I), with a complex hydride reducing agent or a source of a complex hydride reducing agent; and thereafter, as required, preparing a pharmaceutically acceptable salt or a pharmaceutically acceptable solvate of the compound of formula (I) or a tautomeric form thereof.
Abstract:
A sliding and height-adjustable tray shelf unit of a display apparatus has a shelf that slides inward and outward relative to the display apparatus is also adjustable vertically relative to the slotted standard of the display apparatus. Each sliding shelf can also incorporate a removable modular tray in order to allow one tray to be replaced with another tray, perhaps already pre-stocked with items to be displayed. Each sliding shelf also has a support frame that is mounted to the display apparatus or standard by way of hooked prongs or flanges that interact with the slots within the standard. A tray support base or a display tray is mounted to the support frame by any of several ways such that the tray support base “slides” relative to the support frame, such as by wheels that rotate within tracks, pegs or detent tabs that slide forward and backward within tracks cut into a flat surface, and a molded section that slides along an upstanding edge or rail. A display tray can optionally be removably placed into the tray support base for display of merchandise, and the display tray could be pre-stocked with merchandise.
Abstract:
A method of preparing a poly(arylene ether ketone) by a Friedel-Crafts polymerization wherein a gelled reaction mixture is produced, comprising the steps of:(A) forming, in a first reactor, a reaction mixture for polymerization comprising(I) a monomer system comprising(a) (i) phosgene or an aromatic dicarboxylic acid dihalide and (ii) a substantially stoichiometric amount of a polynuclear aromatic comonomer having two active hydrogen atoms or(b) a polynuclear aromatic carboxylic acid halide having an active hydrogen atom; and(II) a Lewis acid in an amount of at least one equivalent per equivalent of carbonyl groups in the monomer system, plus an amount effective to act as a catalyst for the polymerization;(B) permitting the reaction mixture to polymerize in the first reactor until substantial partial polymerization has occurred, but before substantial gelation of the reaction mixture;(C) transferring the partially polymerized reaction mixture into a second reactor having a nozzle at one end thereof and a piston which, in its retracted position, is at the other end of the second reactor and has a stroke substantially equal to the length of the second reactor;(D) permitting polymerization to continue in the second reactor until a gelled, polymerized reaction mixture containing polymer of the desired molecular weight has been obtained;(E) discharging the gelled, polymerized reaction mixture from the second reactor through the nozzle by stroking the piston the length of the second reactor; and(F) recovering and purifying the polymer.
