Window Blinds Offer Shade and Electricity

Everyone is looking for clean energy, because awareness is growing of the problems the use of fossil fuels is creating. Although alternate forms of energy from wind and waves is viable now, solar energy is more accessible to all, since it needs only a solar cell placed in the sun to start generating energy. SolarGaps from Ukraine offers a new type of window blinds that do double duty. You can control the smart shades by an app on your smartphone, and while they screen your house from the fierce rays Read more [...]

What is an i-Robot?

The level of CO2 in our atmosphere is increasing at alarming levels, affecting all life on Earth either directly or indirectly. For instance, it is related to global warming risks, reducing the quantity of ice in the polar regions, which in turn changes the level of seas all around as the ice melts. This has significant consequences on several human activities such as fishing. It also affects the submarine environment adversely, together with the associated biological sphere. For long, scientists Read more [...]

Cloud Storage and Alternatives

Ordinarily, every computer has some local memory storage capacity. Apart from the Random Access Memory or RAM, computers have either a magnetic hard disk drive (HDD) or a solid-state disk (SSD) to store programs and data even when power is shut off—RAM cannot hold information without power. The disk drive primarily stores the Operating System that runs the computer, other application programs, and the data these programs generate. Typically, such memory is limited and tied to a specific computer, Read more [...]

What is a Wireless Router?

Most of the electronic gadgets we use today are wireless. When they have to connect to the Internet, they do so through a device called a router, which may be a wired or a wireless one. Although wired routers were very common a few years back, wireless routers have overtaken them. Routers, as their name suggests, direct a stream of data from one point to another or to multiple points. Usually, the source of data is the transmitting tower belonging to the broadband dealer. The connection from the Read more [...]

What Are PhotoRelays?

Classification of relays include two main groups—contact type or electromechanical relays and contactless type or semiconductor relays. While sub-groups of the mechanical type include signal relays and power relays, those of the contactless type include the solid-state relays and photorelays. Solid-state relays generally use semiconductor photo triacs, phototransistors, or photo thyristors as the output device, and such relays are limited to AC loads alone. On the other hand, photorelays preferably Read more [...]

Nano-Diamonds Help Prevent Lithium Battery Fires

Last year, airline flights banned Samsung Galaxy Note 7s because of its battery-related fires and explosions. Scientists researching the source of the runway beat buildup found the culprit to be small dendrites forming between the anode and cathode of the battery. A materials specialist from the Drexel University at Philadelphia has proposed a low-cost easy solution to preclude dendrite formation. According to Drexel professor Yury Gogotsi, this simply requires mixing nanodiamonds with the regular Read more [...]

What is Better for Quality — Visual or Machine Inspection?

Although the human eye is a wonderfully complex instrument, it has its limitations. For instance, when inspecting objects on the production line, human eye cannot compete with machine vision, as the latter is not only faster, but also accurate to a larger extent. The human eye works in tandem with the brain, allowing us to realize our surroundings. We can recognize things within split seconds, even with their exact shape varying. We can analyze our environment keenly, and although we have a wide Read more [...]

Why Panic Buttons are Going Wireless

Panic buttons or emergency stop switches are extremely important for protecting workers, machinery, and products from catastrophic failures. Traditionally, manufacturers include them with their machinery, and most are hard-wired. However, things are changing and now, these red emergency switches are finally going wireless. When a machine malfunctions, or a critical incident occurs, operators often have to press these last resort switches to bring the system or the entire machine to a halt quickly Read more [...]

Raspberry Pi Drives the Oton Glass

Imagine standing in front of several road signs but unable to locate the one you want, because they are all written in a foreign language. This is the job for the OTON GLASS, a device to capture the image, translate it to a language of your choice, and read it to you in your ear. Not only will this help travelers abroad, but also help people with poor vision and those suffering from dyslexia. Oton Glass is the effort of Keisuke Shimakage, who says he was inspired to develop the device by his father’s Read more [...]

What Are Super-Junction MOSFETs?

Switching power-conversion systems such as switching power supplies and power factor controllers increasingly demand higher energy efficiencies. For such energy-conscious designers, super-junction MOSFETs are a favored solution, as the technology allows smaller die sizes when considering key parameters such as on-resistance. This leads to an increase in current density while enabling designers to reduce circuit size. With increasing market adoption of this new technology goes up, other challenges Read more [...]
