Zero position, directional and dead-man contacts In order to be able to electrically monitor the direction of lever movement and the zero position, a contact can be fitted per half axis. This contact closes when the lever is moved out of its neutral position within the range of ±5 % to ±0 % (referred to the output signal of ±0 V). The transducer can also be fitted with a dead-man switch. This is operated by pressing the upper half of the hand lever (at right angles to the plane of installation). When these functions are required, they are connected via a 2nd non-screened cable.

  • Lecture 11 : Discrete Cosine Transform Moving Into the Frequency Domain
    Lecture 11 : Discrete Cosine Transform Moving into the Frequency Domain Frequency domains can be obtained through the transformation from one (time or spatial) domain to the other (frequency) via Fourier Transform (FT) (see Lecture 3) — MPEG Audio. Discrete Cosine Transform (DCT) (new ) — Heart of JPEG and MPEG Video, MPEG Audio. Note : We mention some image (and video) examples in this section with DCT (in particular) but also the FT is commonly applied to filter multimedia data. External Link: MIT OCW 8.03 Lecture 11 Fourier Analysis Video Recap: Fourier Transform The tool which converts a spatial (real space) description of audio/image data into one in terms of its frequency components is called the Fourier transform. The new version is usually referred to as the Fourier space description of the data. We then essentially process the data: E.g . for filtering basically this means attenuating or setting certain frequencies to zero We then need to convert data back to real audio/imagery to use in our applications. The corresponding inverse transformation which turns a Fourier space description back into a real space one is called the inverse Fourier transform. What do Frequencies Mean in an Image? Large values at high frequency components mean the data is changing rapidly on a short distance scale. E.g .: a page of small font text, brick wall, vegetation. Large low frequency components then the large scale features of the picture are more important. E.g . a single fairly simple object which occupies most of the image. The Road to Compression How do we achieve compression? Low pass filter — ignore high frequency noise components Only store lower frequency components High pass filter — spot gradual changes If changes are too low/slow — eye does not respond so ignore? Low Pass Image Compression Example MATLAB demo, dctdemo.m, (uses DCT) to Load an image Low pass filter in frequency (DCT) space Tune compression via a single slider value n to select coefficients Inverse DCT, subtract input and filtered image to see compression artefacts.

  • Signal Shorts
    Signal Shorts Bill Fawcett Director of Engineering The Problem WMRA has published a coverage map which shows where we expect our signal to reach, based on formulas devised by the FCC. Yet even within our established coverage area, there are locales in which the signal sounds "fuzzy". In most cases, the topography of the area is causing "multi-path" interference, that is, reflections of the signal off of nearby mountains adds to the direct signal, but delayed somewhat in time, and scrambles the received signal. This is the same phenomenon that causes "ghosts" on your TV (shadow- images on your screen, not the "X-Files"). Multipath is a significant problem along the I-81 corridor North of Harrisonburg to Strasburg. Also at Penn Laird along Route 33. Multipath problems are so site-specific that moving a radio a few feet may make a difference. The next time you get a fuzzy signal at a traffic light you may note that it clears up by advancing a few feet (watch out for the car in front of you, or you may have other, more serious, problems). Switching to mono, if possible, will also help. Other areas suffer from terrain obstructions. This may be noted at Massanutten Resort, and in the UVA area of Charlottesville. For those outside of the predicted coverage area, signal strength (the lack of) may be a problem, as may interference. North of Charlottesville this is a big problem, with interference from a high-power station in Washington D.C. causing problems. Lastly, the downtown Charlottesville area suffers from interference from WCYK's 105.1 translator.

  • Telecommunication Facilities
    N. Telecommunication Facilities 1. Purpose The purpose of this section is to provide a uniform and comprehensive set of standards for the development and installation of telecommunications towers, antennas and facilities. The regulations contained herein are designed to protect and promote public health, safety, community welfare and the aesthetic quality of Watonwan County as set forth within the Watonwan County Zoning Ordinance and Watonwan County Comprehensive Plan, while at the same time not unduly restricting the development of needed telecommunications facilities. It is intended that Watonwan County shall apply these regulations to accomplish the following: (a) Minimize adverse visual effects of telecommunications towers, antennas and facilities through design and siting standards. (b) Maintain and ensure that a non-discriminatory, competitive and broad range of telecommunications services and high quality telecommunications infrastructure consistent with the Federal Telecommunication Act of 1996 are provided to serve the community, as well as serve as an important and effective part of the Watonwan County law enforcement, fire and emergency response network. (c) Provide a process for obtaining necessary permits for telecommunications facilities while at the same time protecting the interests of Watonwan County citizens. (d) Protect environmentally sensitive areas of Watonwan County, including the protection of migratory birds, by regulating the location, design and operation of telecommunications towers, antennas and facilities. The following aspects of this ordinance are promoted based on recommendations contained within U.S. Fish and Wildlife Service Guidelines on the Siting, Construction, Operation and Decommissioning of Communication Towers (September 14, 2000): the commitment to exhausting co-location opportunities before allowing new towers, the placement of a maximum height limitation on new towers, the effective prohibition of guyed tower structures, and the prohibition of towers in key habitat areas such as wetlands, shorelands and floodplains.

  • Chapter 3 – Signal and Telecommunication
    Chapter 3 Report No.11 of 2013 (Railways) Chapter 3 – Signal and Telecommunication The Signalling Department is responsible for Safe Train operations and maximizing the utilization of fixed and moving assets such as train rakes, locos and tracks etc. The Telecommunication Department caters for safety related and operational communication needs of the Indian Railway network. The Signal and Telecommunication Organization is headed by Member- Electrical and is assisted by Additional Member (Signal) and Additional Member (Telecommunication). At Zonal level the organization is headed by Chief Signal & Telecommunication Engineer (CSTE) who is assisted by Chief Signal Engineer, Chief Communication Engineer, CSTE (Planning), CSTE (Projects) and CSTE (Construction). Maintaining signalling assets is the primarily the responsibility of the Signalling Department. A thematic study on 'Performance efficiency of Signalling assets – Indian Railways' was conducted by audit covering a period of four years from 2008-09 to 2011-12. The study examined the implementation of the targets laid down in the Corporate Safety Plan (2003- 13) which special focus on monitoring of signal failures and performance efficiency of signal assets. The audit methodology included scrutiny of documents, analysis of data at the S&T branch of Zonal Headquarters (except Metro Railway) and Divisional Headquarters. The related records of 179 Railway stations were test checked for assessing age profile and maintenance schedules of S & T equipments. This chapter contains the audit findings of the above thematic study. 54 Report No.11 of 2013 (Railways) Chapter 3 Performance efficiency of Signalling assets – Indian Railways Executive Summary Modern signalling systems play a key role in enhancing safe and reliable train operations.
