The U.S. manufacturer of car accessories Scosche has introduced the most ingenious remedy while we have seen drastic to eliminate the danger of calls at the wheel: a device that turns off the main functions of your phone as soon as the car begins to move . Only a hammer would be more effective. The device, called Cellcontrol, connects to the OBD diagnostic port of a vehicle-II and then the Bluetooth mobile phone, disabling the function calls, messaging, web browsing and even the use of the camera. The only way to use the mobile is using a hands-free system (detected by Cellcontrol through the phone itself) or to limit their use audio player. Logically, this apparatus is not capable by itself to turn any phone into a brick nearby. To use it you need to install a mobile application available for Android 2.1 or higher, BlackBerry 4.5 or higher, Windows Mobile 5 and 6, Symbian S60 3rd Edition and BREW-based models, which total They are used to analyze the oxygen content of inert gas. These analyzers must be placed before the passage of gas through the cover seals. If the oxygen content of inert gas is greater than 5%, the gas is vented. To measure these teams are based on the paramagnetic properties of oxygen. Oxygen when it is inside a magnetic field tends to move in a direction perpendicular to the field lines. Therefore, if a vessel containing oxygen and magnetic field is applied there will be a movement. Other gases do not exhibit these properties. Within this gas mixture known as inert gas the rest remain motionless. The first analyzer consists of a pipe subjected to a magnetic field that circulates the inert gas. The gas is passed perpendicular to the lines of force. In the center of this line are variable with temperature resistance which has been applied potential difference. The resistance is therefore heated by Joule effect. The gas mixture flowing inside and more oxygen will be a greater movement. This movement will cause greater convection which will cause yield strength heat to cool. Therefore, if a gas is circulated not have oxygen convection is minimal and therefore the temperature of the resistance is maximum. The value of this resistance varies with temperature so that the variation of resistance may result in percent oxygen. To know the value of the resistor is used Wheatstone bridges. This analyzer is also based on the paramagnetic oxygen. The gas is circulated as in the previous case a pipe inside of which is the scale of torque. The magnetic field is applied vertically so that the oxygen flow moves horizontally pushing the torsion pendulum. The pendulum is equipped with a mirror that sunbeam heated throws a beam of light. This light is sent to two photocells. When the pendulum rotates a photocell is illuminated more than the other. The photocell when illuminated transmits a signal to an electric motor that brings back the pendulum to its initial position. To make this work the electric motor has needed an amp, this is the measured and results far Amps, in this case, the percentage of oxygen in the gas following a proportionality. We had the pleasure and privilege to have Javier Jose Amoros Azpelicueta for this inaugural conference, academic hereby solemnly that started tiempla activity and spirits. And I had the strange responsibility to present someone who believes and advocates that speakers should not be presented Due to the needs of consumers, the industry has been evolving projectors to venture to a more casual, more accessible especially common. Therefore, many of the technology empresasde started to launch a series of mini projectors which are noted for their lightness and portability, due to their small size and weight. This time we talk about the BenQ proposed for this segment, it is nothing more and nothing less than the release of GP2 Joybee, a super lightweight projector. It is worth recalling that BenQ is not new to this market and is just a redesign of Joybee mini projector, the new Joybee GP2, which corresponds to the second generation of MiniProyectores BenQ, has a sleek design and features new features and enhancements that will make you decide on the how: Using observations
