TrafFix Devices, Inc. v. Marketing Displays, Inc., 532 U.S. 23 (2001), was a landmark United States Supreme Court decision in the field of trademark law. The case determined that a functional design could not be eligible for trademark protection, and it established a presumption that a patented design is inherently functional.
An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy.

An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...
A T-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers. A T pad can be viewed as being two L sections back-to-back as ...
There also exist optical attenuators that decrease the signal in a fiber optic cable intentionally. Attenuation of light is also important in physical oceanography . This same effect is an important consideration in weather radar , as raindrops absorb a part of the emitted beam that is more or less significant, depending on the wavelength used.
A Π-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers.

The Kh-80 Meteorit-A (GRAU-code: 3M25A, NATO: AS-X-19 Koala), the RK-75 Meteorit-N (GRAU: 3M25N, NATO: SS-NX-24 Scorpion) and the P-750 Meteorit-M (Russian: П-750 Гром, GRAU: 3М25, NATO: SSC-X-5) was a Soviet cruise missile which was supposed to replace subsonic intermediate range missiles in Soviet inventory.
