- Scanned synthesis
Scanned synthesis represents a powerful and efficient technique for animating wavetable synthesis wavetables and controlling them in real time Citation needed date February 2011 . Developed by Bill Verplank, Rob Shaw, and Max Mathews between 1998 and 1999 at Interval Research, Inc., it is based on the psychoacoustics of how we hear and appreciate timbres and on our motor control haptic abilities to manipulate timbres during live performance Citation needed date February 2011 . Scanned synthesis involves a slow dynamic system whose frequencies of vibration are below about 15 Hz Citation needed date February 2011 . The ear cannot hear the low frequencies of the dynamic system. So, to make audible frequencies, the shape of the dynamic system, along a closed path, is scanned periodically. The shape is converted to a sound wave whose pitch is determined by the speed of the scanning function. Pitch control is completely separate from the dynamic system control. Thus timbre and pitch are independent. This system can be looked upon as a dynamic wave table. The model can be compared to a slowly vibrating string, or a two dimensional surface obeying the wave equation . The following implementations of scanned synthesis are freely available Csound features the scanu and scans opcodes developed by Paris Smaragdis. This was the first publicly available implementation of scanned synthesis. Pure Data features the pdp scan and pdp scanxy objects of the PDP extension. Common Lisp Music in circular scanned.clm Scanned Synth VST from Humanoid Sound Systems was the first Virtual Studio Technology VST implementation of scanned synthesis, first released in March 2006 and still being actively developed.

- Counter-scanned images
Counter scanned images CSI, CSIs ref cite journal author R. V. Lapshin year 2007 title Automatic drift elimination in probe microscope images based on techniques of counter scanning and topography feature recognition journal Measurement Science and Technology volume 18 issue 3 pages 907 927 publisher IOP location UK issn 0957 0233 doi 10.1088 0957 0233 18 3 046 url http www.nanoworld.org homepages lapshin publications.htm automatic2007 format PDF ref are a pair of images obtained during counter scanning . During the counter scanning it is possible to obtain one or two pairs of CSIs see Fig. 1 . Each pair consists of a direct image and the image counter to it. The direct image of the second pair is formed by the retrace lines of the direct image of the first pair. The counter image of the second pair is formed by the retrace lines of the counter image of the first pair. CSIs are intended for correction of distortions caused by drift of the Scanning probe microscopy scanning microscope probe relative to the surface under investigation. As compared to a single CSI pair, the use of two pairs requires twice as much memory and processing time but on the other hand it allows increasing precision of correction and reducing noise level in the corrected image. gallery perrow 2 widths 200px heights 200px File R.

- Converting scanned graphs to data
Converting Scanned Graphs to Data Extracting x,y data from scanned graphs can be useful for analyzing data from published graphs, analog instruments, strip chart recordings, or any other hard copy graph or plot. History Developments of the 20th century computer were fueled largely by the needs of the scientific community to store and analyze large amounts of scientific data. With the later development of the personal computer and graphics printer, scientists were able to easily display and print graphical representations of their data sets. In recent years, hardware and software image scanners and digitizing software have been developed that allow scientists to easily extract and therefore analyze data from printed materials such as strip chart recordings, old graphs, and graphs published in journals ... could be extracted from other types of scanned images.

- Passive Electronically Scanned Array
A passive electronically scanned array PESA , contrary to its active counterpart AESA , is a phased array which has a central radiofrequency source such as a magnetron , a klystron or a travelling wave tube , sending energy into usually digitally controlled phase shift module s, which then send energy into the various emitting elements in the front of the antenna radio antenna . AESA devices, in contrast, have each of their elements contain its own radiofrequency source. A PESA radar is therefore simpler to construct than an AESA. Most phased array radars in the world are PESA. Microwave Landing System uses PESA transmit only arrays.
