Tishitu explains
New engineering developments offer opportunities to develop speech technology that can improve the lives of many people who use wheelchairs. In our work, we are designing tomorrow's intelligent wheelchairs: we are developing a voice-commandable intelligent wheelchair that is aware of its surroundings so that it can assist its user in a variety of tasks.
The goal of this smart wheelchair project is to enhance an ordinary powered wheelchair using sensors to perceive the wheelchair's surroundings, a speech interface to interpret commands The robotic wheelchair learns the layout of its environment (hospital, rehabilitation center, home, etc.) through a narrated, guided tour given by the user or the user's caregivers. This technology is appropriate for people who have lost mobility due to brain injury or the loss of limbs, but who retain speech. The technology can also enhance safety for users who use ordinary joystick-controlled powered wheelchairs, by preventing collisions with walls, fixed objects, furniture and other people.
We envision that a voice-commandable wheelchair could improve the quality of life and safety of tens of thousands of users. Moreover, considerable health improvements and cost savings could accrue through the reduction or elimination of collision-induced injuries such as wounds and broken limbs. Our faculty, students, and researchers come from several departments human computer interaction and user interface design, speech recognition systems, and the role of technology for people with disabilities and people who are getting older.

$Tishitu #1 biogas short survey Rajasthan Go Seva Sangh Durgapura Jaipur India Tishitu explains Biogas typically refers to a gas produced by breakdown of organic matter in the absence of oxygen. Organic waste such as dead plant and animal material, animal feces, and kitchen waste can be converted into a gaseous fuel called biogas. Biogas originates from biogenic material and is a type of bio fuel. Biogas is produced by the anaerobic digestion or fermentation of biodegradable materials such as biomass, manure, sewage, municipal waste, green waste, plant material, and crops.[1] Biogas comprises primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulphide (H2S), moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel. Biogas can be used as a fuel in any country for any heating purpose, such as cooking. It can also be used in anaerobic digesters where it is typically used in a gas engine to convert the energy in the gas into electricity and heat.[2] Biogas can be compressed, much like natural gas, and used to power motor vehicles. In the UK, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel.[3] Biogas is a renewable fuel so it qualifies for renewable energy subsidies in some parts of the world. Biogas can also be cleaned and upgraded to natural gas standards when it becomes bio methane. The composition of biogas varies depending upon the origin of the anaerobic digestion process. Landfill gas typically has methane concentrations around 50%. Advanced waste treatment technologies can produce biogas with 55 75% methane,[11] which for reactors with free liquids can be increased to 80-90% methane using in-situ gas purification techniques[12] As-produced, biogas also contains water vapor. The fractional volume of water vapor is a function of biogas temperature; correction of measured gas volume for both water vapor content and thermal expansion is easily done via a simple mathematic algorithm[13] which yields the standardized volume of dry biogas. In some cases, biogas contains siloxanes. These siloxanes are formed from the anaerobic decomposition of materials commonly found in soaps and detergents. During combustion of biogas containing siloxanes, silicon is released and can combine with free oxygen or various other elements in the combustion gas. Deposits are formed containing mostly silica (SiO2) or silicates (SixOy) and can also contain calcium, sulfur, zinc, phosphorus. Such white mineral deposits accumulate to a surface thickness of several millimeters and must be removed by chemical or mechanical means. -~-~~-~~~-~~-~- Please watch: Lifi Communication by Arduino UNO Download Project https://www.youtube.com/watch?v=c4gC8dbaiZg -~-~~-~~~-~~-~-$
