Interacting with objects just looking at them has always been a dream for humans. Eye of Horus is an open source platform to control any device just looking at them. The project (hardware & software) was built from scratch in Zaragoza to solve the a Global Wearables challenge. This device could help physically handicapped people on their tasks. The system combines eye tracking with a frontal camera to know where you are looking. The target devices are identified using light beacons (similar to LiFi technology) and controlled with wireless protocols.

Physically Handicapped people can not control the objects that surround them freely , sometimes can not interact with them. Normal people doing lab and field work often need to ...

Generally a communication system is made-up of “transmitter, channel and receiver.” The architecture of narrowband receivers has had many changes since the beginning of the 19th century, but in recent years (2002~2019), design of multistandard receivers has become very important for designers because users prefer to receive all RF signals (such as Radio, TV, etc.) by one device. Commercial multistandard devices (e.g. Cellphones) are composed of many Surface-Acoustic-Wave (SAW) filters and receiver-circuits in one RFIC package for picking-up and demodulating signals, but recent studies have been focused on wideband Low Noise Amplifier (WB LNA) that these efforts will lead to have a SAW-less multistandard receiver with one WB LNA.

Water is the most important resource, it connects every aspect of our lives. But due to increased population, deforestation, industrialization the water sources are being contaminated, depleting. Today, 1 in 9 people lack access to safe water.

Our proposed solution is a sustainable system which powers itself, monitors the water sources (gathering live data and analysis of the data from livers, lakes, ponds) and alerts officials if any of the parameters are above the standard threshold.

The bot will move through different locations collecting the data. The data is then analyzed to find water quality index. This can prevent contaminated water reaching the consumers and the data gathered can be utilized for further development.

The project proposes a model of variable rate automatic microcontroller based irrigation system. Solar power as known is used as a clean source of energy that can be used in any system and also it is used in this system. Sensors are placed on the paddy field and these sensors continuously sense the water level and give the message to the farmer informing the water level. Without visiting the paddy fields, farmers can get the information about the water level. Based on the water level, a farmer can control the motor by sending a message from his cellular phone even from a remote place. However, if the water level reaches to the danger level; the motor will automatically start ...

Life without a cell phone? Cannot imagine! They are so important that it's as if they are part of our body. But many times cell phone batteries gets discharged while doing some urgent work, call, doing business over a long time etc. Power bank is a solution but again it needs charging and carrying. We made a circuit by which a cell phone battery gets charged while we are working on the phone either by calling or similar work. A copper wire loop and germanium diode along with dc booster and lithium charging modules are used. When the cell phone is used to make a call that time strong cell phone signal radiation gets trapped in wire loop and ...

This project is about building a low cost personal computer or a laptop damper to prevent damage when the laptop falls to the ground. This is done by installing four small structures as seen in the diagram. The four structures are fixed in all four edges of the laptop. The structures have very low weight and each has a small spring that will absorb the force of impact when the laptop falls to the ground. As seen in the figure when the laptop is closed, it cannot be damaged if it falls on any side because all spring dampers cover all the 10 possibilities of falling on the laptop. Also, note that the damper structures have minimal height and ...

Attochron's i-AIR(TM) Fiberless 5G Backhaul: the world's first and only ultrashort pulse laser-based optical wireless telecommunications link -- all others have used 'continuous wave' (CW) lasers. This technology space is generally known as 'free-space-optical communications' (FSOC). Past attempts to beam a CW telecommunications laser through the air (to extend the reach of fiber-optics networks) have been blocked by weather (fog, clouds and separately: clear air 'scintillation'). Attochron's i-AIR solution represents the first time a FSOC system can safely beam through any weather and finally solve this 'propagation' problem over meaningful distances known as 'backhaul' (the No. 1 challenge facing the $T telecommunication market: typically 2 to 5 kilometer high-capacity commercial 'links'). i-AIR is a complementary technology (and not a ...

Write Once, Read Forever (WORF) is a unique, optical data storage media, especially formulated and patented by Creative Technology, LLC, of Hockessin, Delaware (CTech). The media is designed to be resistant to the hostile space environment and is currently being tested by NASA on the International Space Station (ISS).

1. How WORF works.

WORF media stores data in the form of metallic silver halide (AgX) “standing waves” of individual wavelengths of light embedded in a stable, hardened suspension on a substrate, an emulsion specially formulated by CTech. These wavelengths, representing multiple data bytes, can be combined at each data location — defining the next generation for archival and massive, big data storage.

2. What makes WORF novel.

A mm wave soil moisture sensor that can accurately measure moisture quantity in soil avoiding the effect of salt influence on the measurement.

Salt in soil disrupts the accuracy of moister measurement in soil in almost all type of high and low cost sensor in todays market (except TDR type of sensor who are very high cost). This type of low cost sensor can measure the quantity of moisture in a designated field area and transmit moisture data to irrigation hub system for accurate irrigation of the planted field.

Sensor works in a mesh network using very low power where the sensor battery can provide power for several years before its need to be replaced. This type of sensor ...
