Inventions On Using Ldap For Different Purposes-Part-1, Umakant Mishra

Umakant Mishra

The objective of this article is to know how is LDAP used for applications in e-commerce and Policy Management. The analysis of patents shows which Inventive Principles have been used to solve those inventions. Unlike other parts of the study which have tried to improve certain aspect of LDAP technology and application, this article includes the inventions that use LDAP for various different purposes. This article is divided into 3 parts for convenience of size. The first part of the article includes 6 patents using LDAP for “e-commerce” and “Policy Management”. The second part includes 10 patents using LDAP for …

Inventions On Ldap Data Management- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The data model of LDAP is same as X.500 data model. The LDAP protocol assumes there are one or more servers, which jointly provide access to a Directory Information Tree (DIT). The tree is made up of entries. Entries have relative distinguished name (RDN), which must be unique among all its siblings. The concatenation of the relative distinguished names from a particular entry to an immediate subordinate of the root of the tree forms the Distinguished Name (DN) for that entry. (IETF, RFC 2251).

LDAP provides add, delete and modify operations for data modification. Each of these LDAP update operation …

Inventions On Integrating Ldap With Other Directories - A Triz Based Analysis Of Us Patents, Umakant Mishra

Umakant Mishra

Thus the LDAP architecture allows multiple LDAP servers work together on the same directory tree or multiple directory trees. Besides, LDAP being built on an open architecture, it is quite possible to integrate with other directory servers. LDAP can be mapped onto any other directory system so long as the X.500 data and service model as used in LDAP is not violated in LDAP interface. LDAP server may store data in a Flat file, in RDBMS or in any other database. The LDAP client applications can use LDAP directory interface without having knowledge on the underlying data storage mechanism. However, …

Evolution Of User Interfaces For The Visually Impaired- Part 2, Umakant Mishra

Umakant Mishra

Physically or mentally challenged people cannot use a computer in the same way a normal people can. For example, a person with disability in hands cannot use a standard keyboard or mouse efficiently. People having hearing problem, visual challenge etc. cannot interact with a computer like a normal person. So it is necessary to specially design the computers, interfacing devices and software interfaces, which can be used by the physically challenged people.

This article analyses the types of visual disabilities, different assistive technologies for different visual disabilities, guidelines for developing user interfaces for the visually impaired, software products available for …

Physically or mentally challenged people cannot use a computer in the same way a normal people can. For example, a person with disability in hands cannot use a standard keyboard or mouse efficiently. People having hearing problem, visual challenge etc. cannot interact with a computer like a normal person. So it is necessary to specially design the computers, interfacing devices and software interfaces, which can be used by the physically challenged people.

There are many special devices like mouse, keyboard, pointers, and touch screens etc. to assist the visually challenged users. It is a challenge for the inventors and manufacturers …

Inventions On Expressing Emotions In Graphical User Interface, Umakant Mishra

Umakant Mishra

The conventional GUI is more mechanical and does not recognize or communicate emotions. The modern GUIs are trying to infer the likely emotional state and personality of the user and communicate through a corresponding emotional state. Emotions are expressed in graphical icons, sounds, pictures and other means. The emotions are found to be useful in especially in communication software, interactive learning systems, robotics and other adaptive environments. Various mechanisms have been developed to express emotions through graphical user interfaces. This article illustrates some interesting inventions selected from US patent database.
