A linear motor is-simply speaking-an electric motor that uses a linear force mechanism to generate the power needed for a said application. In contrast to a rotational electric motor (found in automobiles, appliances, and commonly-used electrical equipment), a linear motor generates its energy output through exclusively linear scientific principles; i.e. there is no torque or rotation to produce accelerated force through the electrical current magnetic field relationship. Linear motors are used for a variety of purposes, which include high velocity trains, military weaponry, spacecraft exploration, robotic technologies, medical advancement, and automated engineering systems whose job is to produce mass amounts of a specified product.

There are two basic types of linear motors: low-acceleration and high-acceleration. Low-acceleration motors are typically used for applications in which endurance is favored over high bursts of electromechanical power or energy. These types of linear motors are engineered for Maglev trains, automated applications systems, etc. High-acceleration motors are the more common of the two, and produce higher velocity outputs for shorter amounts of time; such as used in firearms, military equipment, spacecraft propulsion, and the like. Low-acceleration linear motors are designed to accelerate an object up to a continuous stabile speed, while high-acceleration linear motors will accelerate an object up to a very high speed and then release the object. Typically, the low-acceleration linear motor will be engineered with one winding system on one side of the motor and magnets on the other side to create the electromagnetic repulsion necessary for successful application force; this is called linear synchronous design. The high-acceleration linear motor will generally be constructed of a three-phase winding on one side and a conductor plate on the other side of the motor to meet the intended engineering objective; this is called linear induction design.

Linear motors offer a number of advantages in this ever-evolving technological world. Whether the high power application your company or organization requires necessitates a low- or high-accelerated lateral motor system, linear motors assure faster acceleration and higher velocities as well as higher success rates in automated accuracy, repeatability, and long-term reliability.

Computer Aided Manufacturing (CAM) is the software automation process that directly converts an object into code and enables the machine to manufacture the product. It is used in various machines like lathes or milling machines for product manufacturing purposes. It allows the computer work instructions to communicate directly to the manufacturing machines.

CAM Resources provide you with various information regarding the actual system, applications, areas of CAM, software used and the detail information of the providers. In the early 1950’s, the technology evolved from the Computer Numerical Control (CNC) machines, which were directed by a set of coded instructions in a punched paper tape. The technology now has more advanced features for quick and reliable manufacturing processes.

CAM software helps you in many ways during the manufacturing of the product. It guides you with much quicker and easier steps to follow. The software is designed and developed with user-friendliness and compatibility. Fully integrated CAD and CAM software is also used to perform various processes within the CAM system. The 2D dimensional constraints also can be used using the software. TurboCADCAM3 software is available with more user-friendliness at reasonable prices. EDC, PTC, AutoDesk and CamSoft are the major software providers in the industry.

The major applications that are used by the CAM system are machines like lathes, welding machines, and robotic milling machines. Other applications that are used by the CAM system are in fields such as mechanical engineering, industrial engineering, aerospace engineering and electrical engineering. The system is considered to be very expensive as it ranges more than $18,000 along with the software.

CAM system mostly works as the integrated unit with the CAD system. A 3D environment is used for the integrated working, which provides you a better and faster manufacturing process. The manufacturing mechanisms that are handled within the system are Computer-Integrated Manufacturing (CIM), Integrated Computer-Aided Manufacturing (ICAM), Flexible Manufacturing System (FMS), Direct Numerical Control (DNC), and Manufacturing Process Management (MPM). The CAM system also controls different factors that involve data verification during manufacturing; panelizing the design to fit in the raw material; and editing and adding manufacturing information.

One of the most important considerations for outdoor security cameras is the power source. Quite often, building codes don’t require many outdoor, electrical connections, which means that if you require an outdoor security camera you’re going to have to deal with that situation. In most cases, there are power sources in the garage that can be utilized for this purpose with a simple bit of concealed wiring. However, if your home or apartment does not have a convenient power source, you may have to create one where you intend the camera equipment to be placed.

Once you’ve solved the power requirements for your outdoor security cameras, you have to do some research on the best equipment for the geographical area that you live in. The system has to be protected from the weather and that means a different system will function best in Tucson, Arizona where the summer temperatures quite often reach and sometimes exceed 120 degrees Fahrenheit, and another system will be used in Maine where winter weather can drive temperatures down as low as -20 degrees Fahrenheit. One system could never function all year around, twenty-four hours a day without being designed especially for the weather.

An additional consideration for outside security cameras is the light source. All cameras require adequate light to properly photograph a subject and video cameras are no exception. This ability to use light is measured as a lux rating. The lower the lux rating of a camera, the less light it needs to deliver a useable image. If you intend to mount your camera in a spot with little or no available light you have to get the lowest lux rated camera you can find that will allow you to see the person in front of the camera.

If this is not possible you have to provide a light source either near or actually on the camera. Finally, if you are not able to provide additional light, you may want to consider infra-red cameras that can deliver a decent enough image in the absence of light.

Cystic fibrosis, which affects 30,000 American children and adults, is a multisystem disease caused by a defective gene. Presently only symptomatic management is possible, but there are very promising gene-therapy trials under way.

In the respiratory system the thin mucus lining becomes thick and sticky. In cystic fibrosis management, the primary treatment of the system is to thin or clear this mucus. Bronco dilators like albuterol are used to clear the clogged airways. Mucus thinning drugs delivered by aerosol, like pulmozyme, are helpful. The most effective way of clearing this mucus is by mechanically dislodging it. Clapping on the chest and back, with the head tilted on the edge of a table, is quite effective. There is an electrical clapper that does the job safely. There is an electrical inflatable vest that vibrates and dislodges the mucus. Infection is an ever-present risk with cystic fibrosis patients. Regular shots for pneumonia and influenza are very important. Bacterial infection is fought with newer antibiotics like TOBY, which delivers the medicine directly into airways with aerosols.

Because of the blocked ducts of the pancreas and liver, the enzymes and bile do not reach the intestine. Though the patient eats normally or even in excess, the fats and proteins are not digested. So the cystic fibrosis patient needs to have the enzymes supplemented with oral pancreatic enzymes. There is also the need to take vitamins, especially the fat-soluble ones. If lung function is completely damaged, the only alternative would be lung transplantation. This would involve many factors, like the availability of a donor and the patient’s present health, prior to undergoing major surgery.

The Cystic Fibrosis Foundation has 115 centers all over America, and provides guidelines and advice. They support many studies to find gene therapy to cure cystic fibrosis. The target is to add normal genes to the cells of the airways to prevent further damage. Biotech laboratories produce healthy genes, which need to be delivered to the appropriate cells. These vectors, or delivery systems, are the key areas of research to combat cystic fibrosis. One method that is actively pursued is to modify the common cold virus to carry the healthy genes into the correct cells. On another track, the DNA molecules are compacted to their minimum size and delivered directly to the relevant cells without the need for a carrier such as a virus. This technology is called PLAS min.

Multi-Contact's range of special test accessories is currently being widely adopted for use with insulation testing instruments up to 5kV.

Proving particularly popular with manufacturers looking to extend the level of inbuilt safety associated with test processes, Multi-Contact's range of special test accessories is currently being widely adopted for use with insulation testing instruments up to 5kV. The Multi-Contact range is characterised by an innovative insulation design promoting the complete compliance of test leads with the demands of IEC/EN 61010-031. By employing a high resistance TPE (thermoplastic elastomer) for lead insulation, the test leads are well equipped to deliver high ohm resistance measurements.

In addition, the inherent safety benefits allow operators to handle the leads in the knowledge that they will consistently withstand intensive energy levels during the measurement stage.

The 5kV product range features three different products, each designed to meet precise manufacturing requirements for optimal operator flexibility.

The XHM-5000 is an extremely flexible test lead incorporating an extended in-line 4mm Multilam plug and rigid insulating sleeve on each end.

In addition, featuring a prod or plug-in facility, the XHL-5000 test probe lead assembly ensures safe handling through an enhanced level of internal and external creepage and clearance.

The range also includes the XHB-5000 socket, easily mounted on panels of various materials and engineered to withstand high voltages.

The socket is specifically designed to accept the extended in-line 4mm Multilam plug fitted on both leads in the 5kV range.

The unique design of the XHB-5000 socket ensures that it is not compatible with standard 4mm safety plugs, significantly enhancing operator safety to eliminate the possibility of lower rated leads or probes being plugged into a high voltage source.

'Building on the advantages of Multi-Contact's unique Multilam interconnect technology, the range is ideal for forming highly efficient connections in HV environments where safety is paramount,' explains Multi-Contact's Selwyn Corns.

'Where high energy levels are present, it is imperative that manufacturers use test accessories that will uphold the highest levels of operator safety.

Our range of accessories for insulation testing devices up to 5kV achieves exactly this, in addition to meeting the demands of the very latest international technical standards.'

Electronic servo AC voltage stabilisers and power conditioners avoid low supply voltage causing malfunction or a high supply voltage causing serious damage.

Watford Control provide leading-edge design with their EMS range of electronic servo ac voltage stabilisers and power conditioners. By combining a process of continuous evolution and technological development with prices that have fallen in real terms, their products are now claimed to offer unrivalled value for money with the highest levels of quality, reliability and performance. All mains powered equipment requires a supply that is maintained within certain limits.

A low supply voltage can cause malfunction and affect the performance and reliability of equipment, while a high supply voltage will cause serious damage.

Microprocessor and computer based equipment requires not only a stable voltage but also a supply that is free of transient spikes and other electrical noise.

Equipment malfunctions or even damage induced by these conditions can be catastrophic for financial institutions (ie banks, insurance companies and building societies).

The operation, quality and performance of production machines can also be affected, with safety and security severely compromised in many other areas including hospitals, supermarkets and other establishments, both large and small.

The Watford range of EMS units extends to over six thousand models with output ratings from 1KVA to 8MVA, covering single or three phase supply applications and incorporating full spike and interference suppression if required.

Output voltage accuracy of +/-0.5% can be maintained over the full range of input voltage variations up to +/-40%, from zero to full load, irrespective of power factor, frequency variations or ambient temperatures from -15deg to +45degC.

Three phase stabilisers will in addition maintain the accuracy of each phase, both line-to-line and line-to-neutral, even in the event of a totally unbalanced supply, load and power factor conditions.

The EMS range provides an ultra fast speed of response, efficiencies up to 99.5%, low internal impedance and the capability of sustaining high surge currents, with negligible waveform distortion.
