Typical pulse as measured with THz-TDS. In physics, terahertz time-domain spectroscopy (THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation.
A tornadic debris signature (TDS), often colloquially referred to as a debris ball, [1] is an area of high reflectivity on weather radar caused by debris lofting into the air, usually associated with a tornado. [1] [2] A TDS may also be indicated by dual-polarization radar products, designated as a polarimetric tornado debris signature (PTDS).
The Ranger Reconnaissance Company has been known to have a very small number of troops, organized into recon teams. As follows: Each team is headed usually by a Master Sergeant, known as the TL. It is usually staffed by 11Bs, 13Fs, and 25 series. There are six teams within the company. All six maintain a general number of men of around six men.
Transderivational search (often abbreviated to TDS) is a psychological and cybernetics term, meaning when a search is being conducted for a fuzzy match across a broad field. In computing the equivalent function can be performed using content-addressable memory .
RPM Ranger Scott Truman followed Professor Cog to the Samurai Rangers' reality. When Professor Cog attacks Scott, the Samurai Rangers joined the fight. Professor Cog then sends the other Samurai Rangers into a vortex leading to Professor Cog's reality while Professor Cog's Hypno-Bolts start to kick in on both Red Rangers causing them to fight.

This technology has significantly more false alarms because many other harmless compounds also have an abundance of nitro groups. For example, most fertilizers have nitro groups which are falsely identified as explosives, and the sensitivity of this technology is also fairly low. A popular detector using this technology is Scintrex Trace EVD 3000.
The Range-R is a hand-held radar device manufactured by L-3 Communications capable of detecting motion through solid walls. The device operates as a finely tuned motion detector, using radio waves to detect the presence of people and movements as small as human breathing at a distance of 50 feet or more.
