A method, system and computer program is provided for protecting against one or more security attacks from third parties directed at obtaining user credentials on an unauthorized basis, as between a client computer associated with a user and a server computer is provided. The server computer defines a trusted Public Key Cryptography utility for use on the client computer. The Public Key Cryptography utility is operable to perform one or more cryptographic operations consisting of encrypting/decrypting data, authenticating data, and/or authenticating a sender, decrypting and/or verifying data. The user authenticates to the Public Key Cryptography utility, thereby invoking the accessing of user credentials associated with the user, as defined by the server computer. The Public Key Cryptography Utility facilitates the communication of the user credentials to the server computer, whether directly or indirectly via an authentification agent, the server computer thereby authenticating the user. In response, the server computer providing access to one or more system resources linked to the server computer to the user. The present invention also provides a series of methods enabling the server computer to authenticate the user by operation of the Public Key Cryptography utility and/or based on enrolment of the user and providing the Public Key Cryptography utility to the user.
摘要:
An interferometric antenna array for use with a wireless communications device in reducing electromagnetic energy in a region proximate to the antenna array. The antenna array comprises two or more radiating elements coupled through circuitry to the wireless communications device. The circuitry operates to appropriately divide a signal from the communications device into a plurality of signals and to phase-shift the plurality of signals such that the electromagnetic wave pattern formed proximate to the antenna array by the two or more radiating elements, which are fed by the phase-shifted plurality of signals, includes a spatial null. The spatial null is located at a region where sensitive electronic equipment, or some portion of a user of the communications device is also located.

A light-weight suction base unit (10) for an upright cleaning apparatus includes a suction base body (20), a left base support (80) associated with the suction base body (20), so that there is a first gap (18) between a portion of the left base support (80) and a portion of the suction base body (20), a right base support (85) associated with the suction base body (20), so that there is a second gap (19) between a portion of the right base support (85) and a portion of the suction base body (20), and a brush roll cavity body (65)associated with the suction base body (20) to form a brush roll cavity (60) having a brush roll cavity intake (70) and a brush roll cavity discharge opening (75). A user is permitted to view a surface being cleaned through the first gap (18) and the second gap (19).
摘要:
A signal processor and method for receiving a digital signal and providing an output signal to a signal receiving device includes a receiver for receiving a digital signal from an antenna and a control circuit for adjusting signal attenuation of the digital signal and generating an output signal. The control circuit includes a variable signal attenuator. The control circuit is operable to sample the output signal and to adjust the variable signal attenuator to adjust signal attenuation and the output signal toward a target output level. The adjusted output signal is communicated to the signal receiving device. The signal processor may include a splitter that receives the output signal of the variable signal attenuator and provides two output signals, one of the output signals being communicated to the signal receiving device and another of the output signals being sampled by the control circuit.

摘要:
Quickly dissolving carrier granule made of wood fibers, mineral filler, and starch-based or dextrin-based adhesive binder. The wood fibers range in length from about 10 microns to about 2 mm. At least about 35 weight-% of the fibers are retained on a 50-Mesh screen. The wood fibers are substantially free of resins such as urea-formaldehyde resin and of diphenylmethane diisocyanate resin. Binders include soluble dextrin binders or viscous corn starch, wheat starch, rice starch, tapioca starch, potato starch, or sago starch binders. The granules have a Resistance to Attrition of at least 90%. Also disclosed is a method of making such granules, and carrier granule compositions made up of from 10 to 90 weight-% of carrier granules wherein the binder is a dextrin binder and from 90 to 10 weight-% of carrier granules wherein the binder is a food-based or industrial-based native starch.

摘要:
The present invention relates to a system and method for authenticating client device (102) users without providing user secrets (316) until a sufficiently high level of assurance of the authenticity of the server (104) is achieved. The user provides identifying information (202) to the server in a series of secure communications. The server responds to the user with a series of stimuli (302, 306, 310, 314) that is known to the user. Only once a sufficient number of rounds of communications are exchanged to authenticate the server does the user send the server a secret (316) which then authenticates the user.
摘要:
Method for manufacturing carrier granules with bulk density less than 40 lbs/ft3 and Resistance to Attrition of at least 95% from mixtures comprising fibers, mineral filler, and binder. The cellulose fibers have bulk density less than 20 lbs/ft3 and moisture content less than 15 weight-%. At least 35 weight-% of the fibers are retained on a 50-Mesh U.S. Sieve Series screen. The mineral filler has moisture content of less than 12 weight-% and bulk density of less than 65 lbs/ft3. The mixture is agglomerated by conditioning and agglomerating it in a pin mixer to form small particles followed by agglomerating it in a disc or pan pelletizer to form substantially spherical granules, which are then dried to a moisture content of less than about 5 weight-% and screened to select granules that pass through a 10-Mesh U.S. Sieve Series screen but are retained on a 40-Mesh U.S. Sieve Series screen.
