An acoustic transmission line is the use of a long duct, which acts as an acoustic waveguide and is used to produce or transmit sound in an undistorted manner. Technically it is the acoustic analog of the electrical transmission line , typically conceived as a rigid-walled duct or tube, that is long and thin relative to the wavelength of sound ...
Endress+Hauser (Endress and Hauser) is a Swiss-based globally operating process and laboratory instrumentation and automation supplier. [2] In 2023, the family-owned business employed over 16,500 people and generated revenue of €3.72 billion. [1] In the field of measurement technology, the group is regarded as a global market leader.

In a transmission line speaker, the transmission line itself can be open ("vented") or closed at the far end. Closed designs typically have negligible acoustic output from the enclosure except from the driver, while open ended designs exploit the low-pass filter effect of the line, and the resultant low bass energy emerges to reinforce the ...
The telegrapher's equations then describe the relationship between the voltage V and the current I along the transmission line, each of which is a function of position x and time t: = (,) = (,) The equations themselves consist of a pair of coupled, first-order, partial differential equations. The first equation shows that the induced voltage is ...
In electrical engineering, transmission-line pulse (TLP) is a way to study integrated circuit technologies and circuit behavior in the current and time domain of electrostatic discharge (ESD) events. The concept was described shortly after WWII in pp. 175–189 of Pulse Generators , Vol. 5 of the MIT Radiation Lab Series.

In the documentary Dangerous Days: Making Blade Runner, Hauer, director Ridley Scott, and screenwriter David Peoples confirm that Hauer significantly modified the speech. . In his autobiography, Hauer said he merely cut the original scripted speech by several lines, adding only, "All those moments will be lost in time, like tears in rain".
