Just like in Mac OS X, you can change the DNS servers on your iPhone. This can significantly speed up Safari and other iPhone apps that use the Internet. For a general introduction to DNS, and to learn why you would want to change the DNS servers on your iPhone, see How to Change Your Mac's DNS Servers.

Before we start, you should know a couple things about how iOS handles DNS. First, these instructions only work for Wi-Fi connections - iOS does not allow you to change the DNS servers when connected to cellular networks. Also, the changes are network specific, so you'll need to change the DNS servers every time you connect to a new wireless network. The good news is that iOS remembers the settings, so you won't have to do anything the second time you connect to a network.

Here's how to change your iPhone's DNS servers:

1. From the iPhone's home screen, tap Settings.
   
   
2. Tap Wi-Fi. The screen shown below appears. The available wireless networks in range of your iPhone appear, as shown below.
   
   
3. Find your wireless network in the list, and then click the arrow. The screen shown below appears.
   
   
4. Tap the DNS field.
   
   
5. Delete the current DNS servers, and enter the new DNS servers. (If you enter more than one DNS server, be sure sure to separate the servers with commas.)
   • To use OpenDNS, enter 208.67.222.222 and 208.67.220.220
   • To use Google DNS, enter 8.8.8.8 and 8.8.4.4
6. Test your new DNS servers to make sure they're working.
   • If you're using OpenDNS, visit the OpenDNS test page.
   • If you're using Google Public DNS, follow these testing instructions.

That's it! You've updated your iPhone's DNS servers!

'It can happen to you anywhere, at any moment, and just change your world'

Replacing the background of a photo can be useful at times if you want to superimpose the subject into a different setting, create a transparency, and so on. In fact it can be extremely helpful if you’ve snapped a photo where the subject looks great, but the background leaves a lot to be desired. Although it might sound fairly complicated to remove and replace the background of a photo, with Movavi Photo Editor it isn’t anywhere near as difficult as you imagine. To be honest even if you have absolutely no experience editing photos, you should be able to change background in a photo in a matter of minutes. To get started, launch Movavi Photo Editor and click on the ‘Browse for Images’ button located right in the middle of the main window. If you prefer you could drag and drop the photo that you want to edit into that area ... Read more

Inspired by Bitcoin, many different kinds of cryptocurrencies based on blockchain technology have turned up on the market. Due to the special structure of the blockchain, it has been deemed impossible to directly trade between traditional currencies and cryptocurrencies or between different types of cryptocurrencies. Generally, trading between different currencies is conducted through a centralized third-party platform. However, it has the problem of a single point of failure, which is vulnerable to attacks and thus affects the security of the transactions. In this paper, we propose a distributed cryptocurrency trading scheme to solve the problem of centralized exchanges, which can achieve trading between different types of cryptocurrencies. Our scheme is implemented with smart contracts on the Ethereum blockchain and deployed on the Ethereum test network. We not only implement transactions between individual users, but also allow transactions between multiple users. The experimental result proves that the cost of our scheme is acceptable.

There is provided an automatic tool changer which, in a precision roll turning lathe which feeds a tool post at a high speed, can automatically change a tool, such as a cutting tool, without stopping the machine, thereby enabling highly efficient ultra-Precision machining of a roll mold for molding of a large-sized plastic sheet. The automatic tool changer includes: a change device including a vertically movable pivot arm having a pivot axis and which pivots in a horizontal plane, a hand portion, mounted at the front end of the arm, for detachably gripping a tool holder, a pivot drive section for pivoting the pivot arm, and a lifting drive section for vertically moving the pivot arm; a tool holder stocker, having a plurality of circumferentially-arranged stages disposed at a predetermined distance from the pivot axis, each stage detachably holding a tool holder; a holder base, mounted to the tool post, for fixing and unfixing a tool holder through the rotation of a clamp shaft; and a clamp shaft operating device including an operating portion for clamping/unclamping the tool holder by rotating the clamp shaft.

A robotic tool changer removably attaches a robotic tool to a robotic arm. The changer includes a tool module connected to the robotic tool, and a master module connected to the robotic arm. To attach and detach the robotic tool, the changer couples and uncouples the tool module and the master module. A master electrical signal module (ESM) affixes to the master module and a tool ESM affixes to the tool module. In accordance with design requirements, the changer applies the same power supply to both the master ESM and the tool ESM. The changer, however, selectively suppresses application of the power supply to the tool ESM, while maintaining application of the power supply to the master ESM, during the coupling or uncoupling of the master module and the tool module. In doing so, the changer enables such coupling and uncoupling, while also preventing the formation of transient electric arcs.

A combination trimming/flame treatment end effector adapted for mounting to the end of a robotic arm. A trimming blade extends from a main body portion of the end effector for performing a trimming operation. The trimming blade may be mounted in an exchangeable cartridge to facilitate blade changing. Also extending from the main body portion is a flame treatment element for performing a flame treatment operation. The flame treatment element generally comprises a torch or burner. Because both the trimming blade and the flame treatment element are part of the same end effector, the robot simply manipulates the end effector such that the desired one of the trimming blade or the flame treatment element is properly positioned for use. As such, a tooling change can be avoided. While not restricted thereto, it is contemplated that an end effector of the present invention may be used to process vehicle bumper fascias.

The tool changer and mated selected removable tool are moved outward toward an outer boundary of the housing and the tool changer extended at least partially outside the housing outward towards a predetermined tool working position. The tool changer is then pivoted to position the selected removable tool to its predetermined tool working position.

Ink in an ink tank is fed through a dissolved gas control filter to a printer head. A gas pressure changing mechanism reduces pressure in a gas pressure control tank. In response, the dissolved gas control filter removes gas dissolved in the ink. The gas pressure control tank is placed under pressure corresponding to a sum of the pressure reduced by the gas pressure changing mechanism and the pressure of the gas having been removed from the liquid. A gas pressure measuring part measures the sum of these pressures as pressure in the gas pressure control tank. Then, a controller determines when time of exchange of the dissolved gas control filter has come based on the magnitude of a gradient of gas pressure variation in the gas pressure control tank.

The building heat exchange system is suited for installation in areas having warmer seasonal climates. The system can include an external solar heated water supply, and an indoor water heater. An enclosure extends around the water heater, with indoor air flowing between the enclosure and water heater to a duct for distribution. During cooler conditions the water heater heats incoming water from the relatively cool external water supply, with the warmth of the water heater warming the air for distribution into the bathroom or other area as desired. In warmer times, the water supplied from the water supply can be sufficiently hot that additional heating is not needed, and can be hotter than desired. In such warmer conditions, the water heater can serve as a radiator, with heat radiated from the water heater being absorbed by air flowing past the water heater and expelled to the external environment.
