LEDs have swept the conventional lighting marketplace for a variety of reasons, most notably their extended lifespans, reduced energy consumption and lower maintenance requirements. By 2030, the DOE estimates that LED lighting could save 190 terawatt hours of electricity per year, which equates to a whopping $15 billion. As the purchase price of lamps and fixtures continues to fall, more and more facility managers are looking to upgrade their lighting systems with LEDs http://www.goldenstarsigns.com/led-lighting/

When you think of a robot, what do you see? A machine that looks a bit like you and me? The reality is that robots can come in many different shapes and sizes. They don't need to look like humans—in fact, most don't. What a robot looks like depends on its purpose. Flying robots might look like helicopters, or have wings like insects or birds. Cleaning robots often look like little vacuums. Robots that are meant to interact with people often have a face, eyes, or a mouth—just like we do! http://www.haofengcncmachine.com/machine-tool-accessories/robots/

Helps maintain a cleaner room and environment. Shoe covers prevent tracking of substances around the building or workspace, which could otherwise damage flooring, pose as a fall hazard, or impair the sterility and cleanliness of the rooms. Even the spread of ordinary dirt and grime can be prevented by contractors such as electricians and plumbers when walking in and out of a customer's home with the help of disposable shoe covers. http://www.hbmurs.com/disposable-shoe-cover/

An indoor playground is an indoor commercial venue packed with play equipment, usually over multiple levels. The idea of an indoor play venue was born in the 1980s and remains extremely popular in the UK today. Most indoor playgrounds are used by children to climb, run, crawl through obstacles and have fun with other kids. There are many hidden benefits when children use an indoor playground, which we will come back to later. http://www.meshalook.com/indoor-playground/

Fast charging cable is designed to do one vital thing — spend less time charging. Nobody wants to wait around tethered to the wall, and Qualcomm does its best to help out. The company’s famed Quick Charge is now on version 5, but you need a powerful cable to achieve peak speeds. Here are the fastest charging cables you can buy right now. It may seem like all cables are the same, but some offer more features and speeds than others. http://www.mobilefieldbrand.com/fast-charging-cable/

Since the introduction of ergonomic guidelines in the design of office chairs, a lot of effort has been put in designing these office chairs accordingly. Because these features all have to be adjusted in different ways (mostly a knob underneath the seat surface), and because every office chair offers different solutions, often users do not use all of the adjustments, and thus do not use the office chair an the optimal ergonomic way. http://www.newtral-chair.com/office-chair/

Silica bricks is a refractory product regarding silicon dioxide as a main component and its content is above 93%. It is made of quartzite as a raw material, and a small amount of mineralizer is added to be fired at a high temperature. It belongs to acidic refractory,which has strong resistance to acid slag erosion, but it is strongly eroded by alkaline slag. It is easily destroyed by oxides containing Al2O3, K2O and Na2O,but it has good resistance to oxides such as CaO, FeO and Fe2O3. http://www.runjinrefractories.com/silica-bricks/

Ball screws are made up of a nut and threaded shaft with hardened steel ball bearings that move on a helical pathway to drive the motion. This use of ball bearings negates much of the friction associated with other screws such as roller and acme, and this lack of friction means that ball screws are 90% efficient or higher, and therefore one of the most effective ways of turning rotary motion into linear motion. http://www.xbrtballscrew.com/ball-screw/

The machine concept differs from the single-twist system in that one rotor turn generates two cable twists / turn. The braid is given the first twist at the stranding point of the system feed. At this point, the stranding material still has twice the length of lay of the desired final geometry. The final braid length of lay with the second stranding twist is only completed at the second turning point, before being introduced back into the static coil former. http://www.jslmet.com/tube-stranding-machine/horizontal-pipe-stranding-machine/double-twist-stranding-machine.html

Common types of beam splitter are either cube beam splitters or plate beam splitters (such as mirrors), as described below. Cube beam splitters are made from two triangular glass prisms glued together, as seen in Fig.2A-C. The thickness of the glue is carefully adjusted so that, for certain wavelengths of light, half the light that enters the cube is reflected 90° and the other half is transmitted through the cube in the same direction as it entered, as seen in Fig.2A. http://www.jxzb-mechanical.com/splitter/
