The individual machine dynamics are taken into account and the simulation can be carried out more realistically. The measured production data can be fed back into the simulation very easily. This improves the quality of the simulation.

ENGEL claims sim link makes problem-free data exchange between simulation and the injection moulding machine possible. This, in theory saves time consuming co-ordination loops between mould development and production.

Most insurance plans at least partially cover these devices when used for OSA, but not if they're used for simple snoring. Don't be tempted to try one unless you've been formally diagnosed with OSA, says Dr. Javaheri. And even if you have OSA, be sure to call your insurance company so you understand how much is covered before you have a device made.

Time-consuming and error-prone manual input of data at the machine is no longer necessary. sim link fulfils this data exchange between simulation software and injection moulding machine without errors.

Keeping your partner — or yourself — up at night with loud snoring? This might be more than a nuisance. About 25% of men and nearly 10% of women have obstructive sleep apnea (OSA), a serious sleep disorder characterized by explosive snores, grunts, and gasps. Tissue at the back of the throat temporarily obstructs the airway, leading to breathing pauses (apneas) throughout the night. Not only does OSA leave people tired and groggy, but it also puts them at risk for a host of health problems, including high blood pressure, depression, and heart disease.

ENGEL claims by using sim link, the number of repetitions could be significantly reduced. The quality of the simulation has also improved and become more accurate. Difficulties in the coordination could thus be successfully overcome.

Several experts are involved in the creation of a new product. sim link simplifies cooperation between simulation and production staff.

"These devices are supposed to reposition your jaw or tongue to open your upper airway. But they can be really uncomfortable and only work about half the time," Dr. Javaheri says. It's hard to predict who might benefit from using an oral device, and people with very mild OSA and few symptoms may not notice any difference. As a result, she generally doesn't recommend them except for people with mild to moderate OSA or those with severe OSA who can't tolerate PAP.

Thanks to effective simulation of injection moulding, cost-intensive looping is reduced when optimising a new component. Where mould makers had to find the values manually for the initial sampling of the moulds, target values are now automatically transferred from the simulation to the injection moulding machine.

ENGEL says experimental methods such as filling studies are often not sufficient and analytical methods lead to better results. however, the problem often arises of establishing a smooth data exchange between software and production.

The most effective and best-studied treatment is positive airway pressure (PAP), a small bedside machine that blows air through a mask to prevent your airway from collapsing. But people with mild or moderate OSA sometimes find PAP challenging to use, and often wonder about alternatives. Dental devices (also known as oral appliances) are an option for some people. But do your homework before going this route, cautions Sogol Javaheri, MD, MPH, MA, a sleep specialist at Harvard-affiliated Brigham and Women's Hospital.

Tongue-retaining devices. These devices consist of a soft plastic splint placed around your tongue that holds it forward and out of your mouth throughout the night. They tend to make your mouth very dry and can be quite uncomfortable.

Every injection moulder faces challenges in achieving its production targets. The most important factor in the development of new products is a short time to market. At the same time, the costs for the development and the optimisation of the moulds must be kept low.

When you wake up in the morning, are you refreshed and ready to go, or groggy and grumpy? For many people, the second scenario is all too common. Improving Sleep: A guide to a good night's rest describes the latest in sleep research, including information about the numerous health conditions and medications that can interfere with normal sleep, as well as prescription and over-the-counter medications used to treat sleep disorders. Most importantly, you’ll learn what you can do to get the sleep you need for optimal health, safety, and well-being.

Mouth guards. Similar to mandibular advancement devices, these devices also help reposition your lower jaw, although to a lesser degree. Some sleep physicians recommend SnoreRx, which you can purchase online for less than $100. Instead of starting with an impression of your teeth created by a dentist, you use what the company calls the "boil and bite" method. You place the device in a cup of boiling water for a minute and then bite down on the softened plastic so it molds to your teeth.

Mandibular advancement devices. Made of molded hard plastic, these devices snap over your lower and upper teeth, and also feature metal hinges and screws that can be tightened to push your lower jaw forward. Some dentists make custom mandibular advancement devices, but before you consider buying a custom device, be sure to ask whether your dentist has experience in sleep-related breathing disorders and is certified by the American Academy of Sleep Medicine. Some non-certified dentists simply take a mold of your teeth, send it to a company that makes the device, then sell it to you at a large markup — sometimes totaling $4,000 or more. What's more, it's unlikely to be covered by your dental or medical insurance if it's used for snoring.
