Implementing Color Machine Vision Inspection Systems

Color provides critical information that can improve the reliability of many machine vision inspection applications and make it possible to inspect many products that cannot be inspected in grayscale. Typical examples include ensuring that a tan rather than a taupe automotive interior component is installed, and checking the position of a black label on a black single-serving coffee cup.

Motion Solutions for Electric Expansion Valves

Expansion valves are flow-restricting devices present in any refrigeration system. The valve needle remains open during steady state of operation. The size of the opening, or position of the needle, is related to the pressure and temperature of the evaporator. When set and controlled properly, an expansion valve will keep the evaporator active throughout its operation.

Hamburg Airport Relies on Drive Technology to Keep Bags Moving

Hamburg Airport in Germany handles nine million pieces of baggage every year. For the baggage handling staff, the reliability of the conveyor system and the prevention of faults are the highest priorities. The breakdown of even a single component of the system would result in a backlog and unacceptable delays.

Servo Motors Help Launch Vehicles Optimize Fuel

Servo motors MICROMO (the FAULHABER Group) Clearwater, FL 800-807-9166 www.micromo.com Space Exploration Technologies (SpaceX) builds economical launch vehicles like the Falcon 9 to carry a range of payloads into orbit. One way to control cost is by optimizing fuel burned during launch to minimize waste. The SpaceX team ensures top performance with the help of a special fuel-trim valve, powered by servo motors from MICROMO. Rockets like the Falcon 9 and Falcon 1 at SpaceX burn a fuel known as RP-1, a highly refined form of kerosene that must be mixed with oxygen in order to burn. On the launch vehicle, 4" pipes run from tanks of RP-1 and liquid oxygen (LOX) to combine prior to entering the combustion chamber. RP-1 fuel won’t burn without oxygen, but as long as oxygen is present, the two do not need to be combined in a precise ratio. The problem is that if the ratio of LOX to RP- 1 varies from the optimum mix, either the oxygen will run out before the fuel, or the fuel before the oxygen. Once combustion stops, the material left becomes dead weight, turning from propellant to liability. To ensure this doesn’t happen, the fuel-trim valve adjusts the mixture in real time.

The Increasing Use of Electrical Actuators in the Aerospace and Defense Industry

Hydraulic and pneumatic systems have traditionally been the market leader in providing power in the aerospace and defense industry because of their low cost and high power density. But in recent years, attention has been focused on the limitations of hydraulic actuators, including their weight, performance, and high maintenance requirements, as well as concerns over their vulnerability due to security issues and other risks.
