How to choose a multifunction printer

Multifunction printers can usually function as a scanner and a copier and are becoming more and more popular in both homes and offices. 

Comparison of mobile operating systems

When choosing a smartphone, the operating system (OS) is the very first important parameter you get to decide, followed by its hardware, functions or design. To help you decide which one to choose, this article offers an overview of the available operating systems and their strengths and weaknesses.

Haptic feedback

A modern control element used mainly in apps and games. Haptic technology is extremely touch-sensitive — modern devices with this technology can detect the degree of pressure you are applying. Different levels of pressure result in different effects. In the settings you can turn on the so-called tactile feedback, which means the system feeds you information on your actions. For example, in car racing, you have no pedals, but you have a steering wheel you can turn. If you strongly press the right side, the car speeds up; if you press the left side, the car slows down. If you press the steering wheel with enough force to trigger the brake function, the steering wheel gently vibrates to let you know it worked.

VoLTE

VoLTE (Voice over LTE) is an LTE technology that enables voice service over LTE. The standard must be supported by both your phone operator and the phone itself in order to work. Its advantages are high call quality and faster network connection.

ZigBee

The ZigBee protocol is the perfect tool for automating the management of smart home appliances, and it plays an important role in the Internet of Things (IoT) world. Its key benefit is the ability to use the devices of different manufacturers while maintaining their mutual compatibility and ease of operation.

Climate Class

Climate classes (T, ST, N, SN) indicate the optimal outdoor temperature in which a freezer will operate. If the outdoor temperature is outside of the recommended range, the freezer's energy consumption increases, which may affect its performance. If a freezer is designated two or more climate classes, this means it will function throughout the whole temperature range. For example, a freezer designated SN-N-ST will operate in an ambient temperature of 10-38 °C.

How to choose an IP camera

Installed in both businesses and households, IP cameras are designed for surveillance of indoor and outdoor spaces. Unlike CCTV, IP cameras can transmit data via a computer network and the internet.

Philips Ambilight

Ambilight ist ein einzigartiges System, das nur Philips in seinen Fernsehern anbietet. Die LED-Lampen an den Seiten des Bildschirms beleuchten die Wand hinter dem Fernseher und um ihn herum in Reaktion auf das aktuelle Bild.

How to Choose a Tablet

With such a wide range of models available, each with a variety of equipment and features, choosing the right tablet can be a tricky process. To help make it easier, we've prepared this handy guide to choose a tablet, which provides a summary of the most important tablet features and parameters.

IPS display

IPS, or In-Plane Switching, often also known as Super TFT, is a type of LCD display technology. It offers an excellent quality-price ratio, natural colours, low power consumption, and wide viewing angles up to almost 180 degrees.

AMOLED display

AMOLED, or Active Matrix Organic Light-Emitting Diode, belongs to the OLED family of display technologies. This is the most advanced display technology on the market. Compared with competing technologies, it boasts faster response times, lower energy consumption, and sharper colours. You can also enjoy perfect black colour reproduction, which results in better readability in direct sunlight. AMOLED displays also offer wide viewing angles, which in the case of IPS displays reach almost 180 degrees. However, the disadvantage of AMOLED technology is its higher price and shorter lifespan.

OLED Display

Often dubbed the display of the future, OLED displays are usually found on premium products. They offer high quality, a broad range of colours, low power consumption, high brightness, and excellent black colour reproduction. As a result, OLED displays are easy to view even in bright sunlight. Another advantage is the wide viewing angle, which reaches nearly 180 degrees.

Mondopoint

Mondopoint drückt die längste Abmessung des Fußes aus. Damit kann geprüft werden, ob der Schuh richtig passen wird.

Ein mögliches Messverfahren ist ein Blatt Papier auf den Fußboden an die Wand zu legen. Barfuß auf das Papier stellen, damit die Ferse die Wand berührt und mit einem Filzstift die längste Zehe des Fußes (in der Regel die große Zeh) markieren. Danach einfach mit dem Meter die Entfernung von der Wand bis zur Markierung messen.

TFT display

A method of rendering LCD-display images. In this case, the image is formed by a thin film of transistors. A thin part of the display consists of small transistors that control individual picture points, or pixels. Unlike previous technologies, it has brought high image quality, high contrast, lower power consumption and smaller size. Today, the biggest advantage of TFT displays is the price. Compared with premium OLEDs, they also have a significantly longer life.

Bluetooth

Bluetooth is the communication tool used by a huge amount of electronics. Learn how the frequency signal is generated and how it's used. In a simple overview of the different versions, we will show how Bluetooth has evolved and been refined. You can also learn something about the specifications and security of this communication standard.

Battery Capacity

A laptop battery's size, along with the efficiency of the components used and software optimisation, determines battery life.

Display Technology

There are currently two main display technologies used - LCD and OLED - which are further divided into different subcategories.

Display Type

Each type of display is suitable for different purposes.
