Smart lighting system for office buildings from Philips

07.04.2014

Philips has announced an innovative smart lighting system for large office buildings that will help reduce energy costs and improve worker comfort.

The presented platform is based on the use of light-emitting diode lighting (LED) devices and Power-over-Ethernet (PoE) technology, which allows the transmission of electrical energy and data exchange over a standard twisted pair cable in an Ethernet network. In other words, Philips proposes to integrate the lighting system with computer infrastructure, which will allow collecting additional information and optimizing the operation of climate complexes.

Thus, LED lamps can be equipped with sensors to measure temperature, humidity and detect people in the room. This will allow the computer program to calculate on which days of the week and hours some rooms are empty, while others, on the contrary, are occupied. Based on this information, you can optimize the operation of heating and air conditioning systems, change the operating mode of LED lamps and adjust the cleaning schedule.

Lighting fixtures can also be equipped with wireless communication chips. In this case, employees using an application for a smartphone or tablet will be able to change the mode of operation of individual lamps in their work area, creating the most comfortable conditions.

Finally, the "smart" lighting system can play the role of a local navigation system: by receiving data on the position of the LED lamps, the mobile application will tell you how to find the right room in a large office building or get to the nearest conference room.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Samsung Galaxy S6 and Galaxy S6 Edge smartphones 04.03.2015

Samsung Electronics has introduced a new flagship smartphone Galaxy S6, as well as its companion - Galaxy S6 Edge with a display curved on both sides.

The front and back panels of both models are made of Corning Gorilla Glass 4, while the side frame is made of metal. The frame is rounded, with holes for the speaker, audio jack and cable connector at the bottom. Thus, the assumptions that the case design will be similar to the Apple iPhone 6 were confirmed, but the information of those sources that reported on the solid metal case was not confirmed.

Almost all the specifications of the Galaxy S6 and Galaxy S6 Edge are the same. Minor differences are present only in battery capacity, dimensions and weight.

The display diagonal is 5,1 inches, the resolution is 2560 x 1440 pixels. Technology - Super AMOLED.
Chipset - 8-core, consisting of two processors with four cores each (architecture ARM big.LITTLE). The frequency of the first processor is 2,1 GHz, the second - 1,5 GHz.

The amount of RAM is 3 GB, built-in - 32, 64 or 128 GB, depending on the model.

The resolution of the front camera is 5 MP. The main camera has a 16 MP sensor and - for the first time in the Galaxy line - is equipped with optical stabilization. There is still a heart rate sensor next to the camera (it is also responsible for white balance). The main camera is easy to launch by double-clicking on the Home button. The camera app launches in 0,7 seconds, according to the company. There is a tracking autofocus function for moving objects.

A fingerprint sensor is hidden under the mechanical button located under the screen. Now his work is more reminiscent of how Touch ID functions in the Apple iPhone and iPad.

The Galaxy S6 and Galaxy S6 Edge support Samsung Pay contactless mobile payments. Communication with the terminal is carried out using NFC or MFT (LoopPay) technology. In addition, the devices received support for wireless charging at once according to two industrial standards - Qi and PMA. Technologies are built into the devices, no additional devices, except for the charging itself, are needed.

As for charging by cable, the company has reduced the time required to fully replenish the charge in the battery by one and a half times compared to the Galaxy S5.

Among other improvements, it is necessary to note the speaker, the volume of which has also been increased by one and a half times compared to the flagship of the previous generation.

New devices were not only purchased, but also lost. Now their case is ordinary, without moisture and dust protection. There is no support for microSD memory cards, the battery cannot be replaced.

The devices are based on Android 5.0 Lollipop.
