In extreme climates, air conditioners can get a huge workout. Summers can be really hard on our system – when air conditioner is operating, dust, dirt and other debris can be drawn in and adversely affect the performance of your unit. So, what happens, and what do you do?

However, no one is looking forward to the high cost of running an air conditioner. During summer, air conditioning accounts for approximately 30% of all energy bills. Since you still have a few weeks before it gets hot, this is the ideal time to be strategic about your air conditioner efficiency.

The biggest problem with a dirty system is that dust can collect on both condenser coil and evaporator. Then ...

The idea of this project is solving the problem of natural user-interaction with Augmented Reality and Virtual Reality (AR/VR) objects through creation of mid-air tactile sensations for related industries (e.g. Microsoft Hololens).

When we hold a “real” object, visual and haptic feedback allow us to feel and interact with it. Current AR/VR 3D-objects can be seen but cannot be touched, which makes the interaction inefficient and awkward. Ultrasound waves can excite haptic sensors of human body. Our solution uses an array of Piezo-electric transducers to create high-resolution ultrasonic patterns. The higher frequency of operation (300 kHz) compared with existing solutions (40 kHz), increases the resolution while reducing the form factor, making it a candidate for mobile applications. Customized ...

Our team at NASA’s Armstrong Flight Research Center developed a highly accurate method for measuring liquid levels using optical fibers. Unlike liquid level gauges currently on the market that rely on discrete measurements to give broad approximations of liquid levels, Armstrong’s innovative fiber optic method provides precise and accurate measurements. Specifically, this novel method is capable of providing measurements at ¼-inch intervals within a tank. This significant leap forward in precision and accuracy in liquid level sensing offers significant benefits to many industries. Dubbed CryoFOSS because it was originally designed to monitor cryogenic fuel levels in rockets using fiber optic sensing system (FOSS) technology, this innovation can be used in many industrial, medical, and pharmaceutical applications.

The sensing system ...

Revolutionary Digital Stepper Device

The Cerfite digital stepper device can travel at two or more speeds, precisely variable or steady, stop in place and hold position while power is off. It uses little power allowing it to operate wirelessly. Due to same material interface, there is no known appreciable wear. There are not any gears or chains required. It may be made in any size, any configuration. Lightweight, non conductive ceramic won't cause sparks. Small dots are made on the base at varying angles signifying the odd and even precise steps. Another odd even row of dots allows larger steps for accurate skewing.

The device may operate in any environment it requires no cooling or batteries. Power may be ...

NASA’s Jet Propulsion Laboratory has developed a next generation, direct-feed fuel cell that is cleaner, cheaper, and more efficient than existing fuel cells. Methanol fuel cells use an oxidation/reduction reaction to generate electrical power without polluting the air or burning non-renewable fossil fuels. This reaction requires equal amounts of methanol and water, which makes conventional fuel cell vehicles impractically heavy. JPL’s methanol fuel cell is able to recycle the water that is used during its reaction, so a vehicle powered by JPL’s fuel cell would be lighter and more efficient. In addition, while state-of-the-art fuel cells use an expensive platinum catalyst to drive their chemical reactions, JPL’s fuel cell uses a more efficient catalyst that almost entirely eliminates the ...

The objectives of this research is to design and test a suitable set of drip irrigation powered by solar cell. Solar panel is used to charge the battery which helps to run the motor in irrigation field. Soil moisture sensor measure the moisture level in the soil. If the moisture level drops below 40%, then motor is switched ON automatically to pump the water to irrigation field, until the moisture level reaches to 40%. Then the motor is switched OFF.

In this project as designed for drip irrigation powered by solar cell for dry rain fed and no electricity area. In the solar power panel get energy from renewable source of sun. This energy can be stored and ...

My submission for the contest is an Expandable cell phone which has a feature of expanding its physical size from a cell phone to that of a tablet. This feature will enable the user to carry a small cell phone which is easy to handle but it can be stretched and transform into a tablet whenever required. It sounds good and can serve a lot to the user.

The feature can be enabled in two ways:

1. We can make an extra frame for the expansion, inside or backside of the phone by making some precise electro-mechanical adjustment, which will come out when the user wants to expands his phone for watching a movie or playing a game.

2. ...

FED / Fast, - ergonomic display design technology /.

Machine operator reaction on the information signal change is a complex process. Electronics consumer while perform the operator work, require the full information on the screen, successful ergonomic time capacity to read, to react on the environment that may change the situation. Digital value in an electronics design often lose the parameters in a favor of the reasons of the better fashion design, economic, poor modeling. Universal process value displaying ergonomically substitute locomotion or vision nature.

Three positions display is better ergonomically resolve operator receiving data. Direction of process is the main portion of information signal delivered by Fast Ergonomic Display. Effectiveness was tested in a reaction measure single and ...

Over the last few decades, the use of public transportation has been attractive to most of the people. The increase in passenger count has made ticket vending and vehicular monitoring a complex task. In addition to this, frequent accidents occur due to overload of passengers and these accidents are not cognizant to the rescuers. The main objective of the Fingerprint Based Smart Pay and Accident Alert System is to design an automatic ticket vending system by Fingerprint access. This is also aimed at creating an alerting system when the vehicle is met with an accident.

Fingerprint Based Smart Pay and accident alert System would be an excellent replacement to the existing traditional ticketing system by a simpler biometric scan that ...

The main objective of this project is to make life comfortable and easier for disabled and elderly people by using a handheld smart controller device. The smart controller device which is designed suits all types of disabled people such as the deaf, dumb and physically challenged.

The project demonstrates a system that can be integrated as a single portable unit and allows one to wirelessly control lights, fans, air conditioners, television sets, security cameras, electronic doors, computer systems, audio/visual equipment, etc. and turn on or off any appliance that is plugged into a wall outlet, get the status of different sensors and make decisions accordingly. The overall system is controlled from a microphone, FLEX Sensor and PIC. This chip sends the voice ...
