He worked on this device while living in Yonkers, New York in 1852, and had a finished product in 1854.

Herzstark worked hard to move his invention from his knowing how to build the device " in principle " to concise working drawings for a manufacturable device.

Jeff Tanner ( programmer ), a former Macromind employee who worked for John Thompson ( inventor ) in developing and testing initial Lingo for Macromedia Director 2. 2 and 3. 0, created custom XObjects for various media device producers, language extension examples using XFactory including the XFactory API, and wrote the initial tutorials on how to use Lingo.

A height gauge is a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on.

Others had worked on using jets, particularly Bourdon who patented a very similar device in 1857.

After carrying out some experiments, he came up with a new device that worked well and used less power than the one it replaced.

Although the Taylor Scale was designed as a group testing device, in this study it was individually administered by psychologically trained workers who established rapport and assisted the children in reading the items.

Babbage's first attempt at a mechanical computing device, the Difference Engine, was a special-purpose calculator designed to tabulate logarithms and trigonometric functions by evaluating finite differences to create approximating polynomials.

The Expansion module is designed as a pass-through device that sits on top of the console and requires no system modding.

A beacon is an intentionally conspicuous device designed to attract attention to a specific location.

Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range ( power-class-dependent, but effective ranges vary in practice ; see table below ) based on low-cost transceiver microchips in each device.

To gain some of the advantages afforded by both lower and higher bit lengths, many CPUs are designed with different bit widths for different portions of the device.

When a device is designed to perform without the need of human inputs for correction it is called automatic control ( such as cruise control for regulating a car's speed ).

Consider a car's cruise control, which is a device designed to maintain vehicle speed at a constant desired or reference speed provided by the driver.

Device mirroring and typical RAID are designed to handle a single device failure in the RAID group of devices.

Device mirroring and typical RAID are designed to handle a single device failure in the RAID group of devices.

The first electrical engineer was probably William Gilbert who designed the versorium: a device that detected the presence of statically charged objects.

* Filter ( chemistry ), a device ( usually a membrane or layer ) that is designed to physically block certain objects or substances while letting others through

This is not usually a problem after the device has been installed in a properly designed circuit.

He designed the first instruments used in satellites to measure cosmic radiation and ozone, and in 1951 or 1952 designed the MOUSE (" Minimal Orbital Unmanned Satellite, Earth "), a proposed satellite that would contain Geiger counters for measuring cosmic rays, photo cells for scanning the Earth, telemetry electronics for sending data back to Earth, a magnetic data storage device, and rudimentary solar energy cells.

Some magazines, such as that of most centerfire hunting rifles and all revolvers, are internal to and inseparable from the firearm, and are loaded by using a clip, which is a device that holds the ammunition by the rim of the case and is designed to assist the shooter in reloading the firearm's magazine.

A land mine is an explosive device, concealed under or on the ground and designed to destroy or disable enemy targets as they pass over or near the device.

Note the yellow main charge wrapped around a red explosive booster | booster charge, and the secondary fuze well on the side of the mine designed for an anti-handling device

After a certain period of time, either the charge dissipates, leaving them effectively inert or the circuitry is designed such that upon reaching a low level, the device is triggered, thus destroying the mine.

Often, single mines are backed by a secondary device, designed to kill or maim personnel tasked with clearing the mine.
