Solving Problems Of Virus Definition Files - A Triz Perspective, Umakant Mishra

Umakant Mishra

Signature scanning is the most popular method of virus scanning and is adopted by all anti-virus programs. Signature scanning is capable of detecting more than 80% of viruses. It uses a simple logic and uses less memory and system resources. Although it has a lot of advantages, it has one big disadvantage. It requires the virus signature to be extracted by the experts and stored in a database called “virus signature database”. This virus signature database has to be updated by the anti-virus developers and the end users periodically in order to deal with the latest viruses.

A typical virus …

Inventions On Ldap Data Storage- A Study Based On Us Patents, Umakant Mishra

Umakant Mishra

Lightweight Directory Access Protocol (LDAP) is an IETF open standard to provide directory services in the network. LDAP was initially developed at the University of Michigan with an objective to include most of the features of X.500 directory structure, while eliminating the burdens and difficulties of the same.

As LDAP does not provide any specification on the data storage, different venders can implement different mechanism for data storage as found suitable to the specific vender or environment. Although underlying data storage system between different LDAP servers can differ, this disparity does not affect the functionality or interaction of LDAP clients. …

Inventions On Ldap Security- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The specifications of LDAP v.3 provide facilities for simple authentication using a cleartext password as well as any SASL mechanism.SASL allows for integrity and privacy services to be negotiated (RFC 2251, www.ietf.org/rfc/rfc2251.txt). Use of cleartext password is strongly discouraged where the underlying transport service cannot guarantee confidentiality and may result in disclosure of the password to unauthorized parties. The protocol allows other security mechanisms like SASL to be implemented in LDAP. The protocol also permits that the server can return its credentials to the client, if it chooses to do so. This article is a TRIZ based study on patents …

Umakant Mishra

A keyboard is the most common and widely used input device for a computer. Using the keyboard is often vital to interact with a computer. There are several aspects of a keyboard such as size, key layout, convenience and ergonomic features etc., which are continuously under improvement by keyboard designers and manufacturers. TRIZ is an efficient methodology in product designing. Using IFR and Trends we can well predict the directions of the future keyboards and using Contradictions and Principles we can overcome the current limitations. This article analyses the critical features of a keyboard, does a functional analysis, derives the …

Inventions On Drag And Drop In Gui, Umakant Mishra

Umakant Mishra

Drag and drop operation is one of the key capabilities of any Graphical User Interface. The user can do quite complex operations simply by visually dragging and dropping objects from one location to another. It saves user from remembering and typing a lot of commands. The result of a drag and drop operation may vary depending the type of source object and type of destination object. For example dragging a file and dropping on a folder may copy or move the file to the destination folder, dropping that file to a remote ftp location may upload that file using internet, …

Inventions On Using Sound And Speech In Gui, Umakant Mishra

Voice recognition facilitates a human interaction with the machine. VR may be used to replace the manual task of pushing buttons on a wireless telephone keypad. This is particularly useful when the hands of the user are busy with other activities like driving a car.

However, the VRS system has several limitations. The VRS requires lot of training and customization in order to be effectively used by individual users as each individual falls into different voice patterns. Besides the voice interface is complex and is not as reliable as the keyboard or mouse. This article illustrates some interesting inventions on …

The article illustrates some inventions on eye-cursor control system, which attempt to eliminate the difficulties of the prior art mechanisms.

Keyboards For Inputting Japanese Language: A Study Based On Us Patents, Umakant Mishra

Umakant Mishra

The most commonly used Japanese alphabets are Kanji, Hiragana and Katakana. The Kanji alphabet includes pictographs or ideographic characters that were adopted from the Chinese alphabet. Hiragana is used to spell words of Japanese origin, while Katakana is used to spell words of western or other foreign origin.

Two methods are commonly used to input Japanese to the computer. One, the “kana input method” that uses a keyboard having 46 Japanese iroha (or kana) letter keys. The other method is “Roma-ji input method”, where the Japanese letters are composed of English input from a standard QWERTY keyboard. Both the methods …
