  Medical Device Link - The Online Information Source for the Medical Device Industry
From simple drainage catheters to complicated neurological and cardiovascular catheters, catheter designs must be robust, they must be able to be produced reliably, and their quality must be reproducible.
In the medical device industry, blazing a successful trail into uncharted technological and clinical areas sometimes takes a couple of tries.
End-users voiced complaints that sterile device packaging often lacks an intuitive design and, consequently, attempting to open such a package incorrectly could compromise device sterility.

  Medical Device Use--Safety: Incorporating Human Factors Engineering into Risk Management
Devices that can be used safely under conditions of low stress (i.e., low workload) could be difficult or dangerous to use under conditions of high stress.
Users will expect devices and device components to operate in ways that are consistent with their experience with other similar devices or device interface components.
For example, some devices include "interlocks," or mechanisms that prevent a critical process from being initiated without users verifying their intent to initiate it or necessitating extra control steps to be performed before proceeding.

 Device driver - Wikipedia, the free encyclopedia
The function of the device driver is then to translate these OS mandated function calls into device specific calls.
Writing a device driver is considered a challenge in most cases, as it requires an in-depth understanding of how a given platform functions, both at the hardware and the software level.
All of this means that the engineers most likely to write device drivers come from the companies that develop the hardware - since they have more complete access to information about the design of their hardware than most outsiders.

 DEVICE - Definition
A device usually has reference to something worked out for exhibition or show; a contrivance usually respects the arrangement or disposition of things with reference to securing some end.
Devices were worn by knights-errant on their shields; contrivances are generally used to promote the practical convenience of life.
The word device is often used in a bad sense; as, a crafty device; contrivance is almost always used in a good sense; as, a useful contrivance.

 device - a Whatis.com definition
2) In the context of computer technology, a device is a unit of hardware, outside or inside the case or housing for the essential computer (processor, memory, and data paths) that is capable of providing input to the essential computer or of receiving output or of both.
The units of a computer to which the term device is not applied include the motherboard, the main processor and additional processors such as numeric coprocessors, and random access memory (RAM).
The term peripheral (a truncation of peripheral device) is sometimes used as a synonym for device or any input/output unit.

 Device Polling support for FreeBSD
"Device polling" (polling for brevity) refers to a technique for handling devices which does not rely on the latter to generate interrupts when they need attention, but rather lets the CPU poll devices to service their needs.
The latency for processing device events is thus upper bounded by one clock tick (that is, when the system is not overloaded).
The system replaces interrupt-based handling of network devices with a mixed interrupt-polled mode ("polling" for brevity), where polling-enabled network cards will be polled at every clock tick, in the idle loop, and optionally at each system call.

 The Enterprise Mission - Anti-Gravity
Measuring about 12in across, the device is said to reduce significantly the weight of anything suspended over it.
By using the devices to raise fluids against gravity, and then conventional gravity to pull them back to earth against electricity-generating turbines, the devices could also revolutionise power generation.
In recent years, many so-called "anti-gravity" devices have been put forward by both amateur and professional scientists, and all have been scorned by the establishment.

For miscellaneous character devices a second step is required: there is a scan for the driver entry with the same minor number as the file that was opened, and the appropriate minor open method is called.
The devfs solution allows a device driver to "tag" certain device files so that when an unopened device is opened, the ownerships are changed to the current euid and egid of the opening process, and the protections are changed to the default registered by the driver.
