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 …

Inventions On Gui For Eye Cursor Controls Systems, Umakant Mishra

Umakant Mishra

Operating a GUI through eyeball is a complex mechanism and not used as often as mouse or trackball. But there are situations where eye-mouse devices can play a tremendous role especially where the hands of the user are not available or busy to perform other activities. The difficulties of implementing an eye-cursor control system are many. The article illustrates some inventions on eye-cursor control system, which attempt to eliminate the difficulties of the prior art mechanisms.

Impact Of Interconnection Photovoltaic/Wind System With Utility On Their Reliability Using A Fuzzy Scheme, Dr. Adel A. Elbaset

Dr. Adel A. Elbaset

Reliability analysis has been considered as an important step in any system design process. a reliable electrical power system means that the system which having sufficient power to feed the load demand during a certain period or in other word, having small Loss of Load Probability (LOLP). LOLP is defined as an expected fraction of load not met by its needed power from electrical power system during its lifetime. Photovoltaic (PV) / Wind Energy System (WES) hybrid electric power system (PV/WES HEPS) differs considerably from the utility grid (UG) in their performance and operating characteristics. With the interconnection of PV/WES …

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 …

Mil-Std-188-125-1, High-Altitude Emp Protection For Fixed Ground-Based Facilities

George H Baker

MIL-STD-188-125-1 establishes minimum requirements and design objectives for high-altitude electromagnetic pulse (HEMP) hardening of fixed ground-based facilities that perform critical, time-urgent command, control, communications, computer, and intelligence (C4I) missions. The standard prescribes minimum performance requirements for low-risk protection from mission-aborting damage or upset due to HEMP environments. It also addresses minimum testing requirements for demonstrating that prescribed performance has been achieved and for verifying that the installed protection subsystem provides the operationally required hardness for the completed facility. Covered fixed ground-based facility types include subscriber terminals and data processing centers, transmitting and receiving communications stations, and relay facilities. Use of …

10 Inventions On Reducing Keyboard Size, Umakant Mishra

Umakant Mishra

A conventional computer keyboard consists of as many as 101 keys. The keyboard has several sections, such as text entry section, navigation section, and numeric keypad etc. and each having several keys on the keyboard. The size of the keyboard is a major inconvenience for portable computers, as they cannot be carried easily. Thus there are certain circumstances which compels to reduce the size of a keyboard. Reducing the size of a keyboard leads to several problems. A reduced size keyboard may not contain all the keys available on a full size keyboard; a reduced size keyboard may not be …

Advances In High Resolution Imaging From Underwater Vehicles, Hanumant Singh, Christopher Roman, Oscar Pizarro, Ryan Eustice

Christopher N. Roman

Large area mapping at high resolution underwater continues to be constrained by the mismatch between available navigation as compared to sensor accuracy. In this paper we present advances that exploit consistency and redundancy within local sensor measurements to build high resolution optical and acoustic maps that are a consistent representation of the environment.

We present our work in the context of real world data acquired using Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs) working in diverse applications including shallow water coral reef surveys with the Seabed AUV, a forensic survey of the RMS Titanic in the North Atlantic …

Grams: A Grid Resource Analysis And Monitoring System, Hong-Ning Dai, Minglu Li, Linpeng Huang, Yi Wang, Feng Hong

Hong-Ning Dai

In this paper we propose GRAMS which is a resource monitoring and analysis system in Grid environment. GRAMS provides an infrastructure for conducting online monitoring and performance analysis of a variety of Grid resources including computational and network devices. Based on analysis on real-time event data as well as historical performance data, steering strategies are given for users or resource scheduler to control the resources. Besides, GRAMS also provides a set of management tools as well as services portals for user not only accessing performance data but also handling these resources. Moreover, a preliminary system prototype is presented.

10 Inventions On Keyboard Attachments: A Triz Based Analysis, Umakant Mishra

Umakant Mishra

Although the primary objective of the keyboard to input data into the computer, the advanced keyboards keep various other things in mind, such as, how to use the same keyboard for various other purposes, or how to use the same keyboard efficiently by using various other attachments to the keyboard. This objective led to various inventions on keyboard attachments, some of which are illustrated below in this article. This article illustrates 10 inventions on various keyboard attachments from US patent database. Each different attachment improves the usability of the keyboard in some way or other. Some attachments illustrated are template …
