Architecture for detecting and removing obfuscating clutter from the subject and / or body of a message, e.g., e-mail, prior to filtering of the message, to identify junk messages commonly referred to as spam. The technique utilizes the powerful features built into an HTML rendering engine to strip the HTML instructions for all non-substantive aspects of the message. Pre-processing includes pre-rendering of the message into a final format, which final format is that which is displayed by the rendering engine to the user. The final format message is then converted to a text-only format to remove graphics, color, non-text decoration, and spacing that cannot be rendered as ASCII-style or Unicode-style characters. The result is essentially to reduce each message to its common denominator essentials so that the junk mail filter can view each message on an equal basis.

This feature provides the host the ability to simultaneously erase any combination of sectors in a single erase group, or any combination of the entire erase groups. Another feature feature provided by this novel method of partitioning the memory storages is the ability to write protect any combination of memory groups in the card.

An object of the present invention is to provide a method for encoding signals by separating a signal by using a common multiplier so as to improve the efficiency of compression of audio signals and a method for calculating a common multiplier of a set of numeric values including errors. A common multiplier A, of the input signal samples x(i) in each frame is estimated. Each sample x(i) is divided by A, the quotient is rounded to the number of significant digits, and the rounded quotient y(i) is encoded. The quotient y(i) is multiplied by A and the product is subtracted from x(i) to obtain an error signal z(i), which is then encoded. The multiplier A is encoded and the code of y(i), the code of z(i), and the code of A are combined together and outputted. To estimate the common multiplier, each numeric value is divided by a determined representative value. Irreducible fractions between the maximum positive error and the maximum negative error are obtained by dividing each numeric value by a correct representative value using rational approximation. Among the obtained irreducible fractions, the one having the smallest common denominator of the numeric values is obtained and the common denominator is corrected using the representative value to obtain a common multiplier.

Embodiments herein are designed to counteract the negative effects of an attendee join in a remote session by employing several techniques. One technique maintains and determines maximum decoding capabilities of viewers, which are then used to determine, e.g., a least common denominator of encoding available. As such, a sharer can dynamically modify (either up or down) the encoding of the graphics stream without having to renegotiate decoding capabilities for each viewer upon a join / disjoin. In order to assist in resetting viewer state based on the above encoding technique, other embodiments provide for: context reset for delta and / or other types of order encoding; reset for all sharer and viewer caches; and reset of history for compression context. Another technique provides for delaying the joiner of attendees (and thus the reset of the graphics stream) based on a myriad of static and dynamic policy factors.

Access management techniques have been developed to specify and facilitate mappings between I / O and host domains in ways that provide flexibility in the form, granularity and / or extent of mappings, attributes and access controls coded relative to a particular I / O domain. In some embodiments of the present invention, operation translations coded relative to a particular logical I / O device, domain or sub-window seek to optimize functionality, isolation or some other figure of merit without regard to needs or limitations of another. In this way, operation translations need not be uniform and need not reduce supported operation semantics to correspond to that of a lowest common denominator I / O device. In some embodiments, the form of mappings (e.g., of operation translations) may be specialized on a per-logical-device basis (or even a per-sub-window basis), thereby offering individual logical I / O devices (or sub-windows thereof) immediate, indexed, and / or untranslated operation mapping frameworks appropriate to their individual requirements or needs. In general, flexibilities and efficiencies afforded in some embodiments of the present invention can be desirable, particularly as the diversity of I / O device types and richness of transaction semantics supported in interconnect fabrics increase. Some embodiments may be leveraged in support of sophisticated system partitions or I / O virtualizations.

A random number that is co-prime with a set of prime numbers is generated, without having to calculate the greatest common denominator of the numbers. The value of 1−xλ(mod π), where x is a randomly generated value and λ is the Carmichael function, is tested to determine whether it is non-zero.

Due to the minimal amount of computation resources required to select x, the process is particularly well suited for generating cryptographic keys in portable electronic devices, such as smart cards.

Wireless devices communicate (using SMS messaging) with a proxy server (e.g., a wireless messaging gateway) to generate network initiated requests. In this way, a wireless device which might not otherwise be able to, can now participate in advanced applications such as location based services (LBS) communities, thus extending LBS presence type information to non-programmable wireless devices. Short messaging system (SMS) functionality is implemented as a least-common-denominator means enabling standardized communication between a wireless device and a wireless device application.
