  2. Receiver (firearms) - Wikipedia

    en.wikipedia.org/wiki/Receiver_(firearms)

    A disassembled Mauser action showing a partially disassembled receiver and bolt. In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing for internal action components such as the hammer, bolt or breechblock, firing pin and extractor, and has threaded interfaces for externally attaching ("receiving ...

  3. AC adapter - Wikipedia

    en.wikipedia.org/wiki/AC_adapter

    Switched-mode power supplies (SMPSs) are much more efficient; a good design can be 80–90% efficient, and is also much smaller and lighter. In 2002 most external plug-in "wall wart" power adapters commonly used for low-power consumer electronics devices were of linear design, as well as supplies built into some equipment.

  4. Arado Ar 80 - Wikipedia

    en.wikipedia.org/wiki/Arado_Ar_80

    The design, now known as the Ar 80, was completed without the aid of Rethel; he left the company in 1934 to join BFW leaving Blume in charge of the project. The plane was designed to mount the Jumo 210 engine, driving a wooden two-blade fixed-pitch propeller.

  5. McDonnell Douglas F/A-18 Hornet - Wikipedia

    en.wikipedia.org/wiki/McDonnell_Douglas_F/A-18...

    McDonnell filled in 80% of the gap, leaving a small slot to bleed air from the engine intake. This may have contributed to early problems with fatigue cracks appearing on the vertical stabilizers due to extreme structural loads, resulting in a short grounding in 1984 until the stabilizers were strengthened. Starting in May 1988, a small ...

  6. Universal asynchronous receiver-transmitter - Wikipedia

    en.wikipedia.org/wiki/Universal_asynchronous...

    The "stop bit" is actually a "stop period"; the stop period of the transmitter may be arbitrarily long. It cannot be shorter than a specified amount, usually 1 to 2 bit times. The receiver requires a shorter stop period than the transmitter. At the end of each data frame, the receiver stops briefly to wait for the next start bit.

  7. DisplayPort - Wikipedia

    en.wikipedia.org/wiki/DisplayPort

    DisplayPort cables up to 2 meters in length are required to support the full 10.8 Gbit/s bandwidth. [8] DisplayPort 1.1 allows devices to implement alternative link layers such as fiber optic , allowing a much longer reach between source and display without signal degradation, [ 9 ] although alternative implementations are not standardized.

  8. Spectrum analyzer - Wikipedia

    en.wikipedia.org/wiki/Spectrum_analyzer

    This is commonly used in conjunction with a receiver and analog-to-digital converter. As above, the receiver reduces the center-frequency of a portion of the input signal spectrum, but the portion is not swept. The purpose of the receiver is to reduce the sampling rate that the analyzer must contend with.

  9. Receiver operating characteristic - Wikipedia

    en.wikipedia.org/wiki/Receiver_operating...

    A classification model (classifier or diagnosis [7]) is a mapping of instances between certain classes/groups.Because the classifier or diagnosis result can be an arbitrary real value (continuous output), the classifier boundary between classes must be determined by a threshold value (for instance, to determine whether a person has hypertension based on a blood pressure measure).
