Fingers with dual slope and three distinct sections: gas–liquid separation, intermediate and storage sections. This is used in the AD7550 13-bit A/D converter manufactured by Analog Devices. d) 1000 This increased immunity stems from the fact that errors introduced during the positive slope will be largely offset by similar errors during the negative slope. Methods of Distribution of Superelevation and Side Friction 5 methods y Methods #2 and #5 are the most common Method #2: Side friction is such that a vehicle has all lateral acceleration sustained by side friction. For instance, the capacitance may change due to temperature variation. In fact, if more liquid is brought in than the slug catcher can handle, the plant normally shuts down. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Figure 2. At high slopes, pulling generated more compression and shear forces than that of pushing (p < 0.01). The positive slope of a dual-slope converter is determined by the value of analog input voltage. The output of the op amp will have a slope that is linear but twice as great, since the amplifier has a voltage gain of 2. c) no effect Knowing a vehicle’s approach angle and departure angle clearances will make negotiating obstacles off-road a lot easier. Figure 1-1. This integration takes place at a set slope since the magnitude of the reference voltage is set. This “oversampling” (a sampling clock of several MHz used for input bandwidths of a few kHz) allows for extremely high resolution and low distortion. Figure 6-81:. With the counter reset, the MSB will be 0 and the analog switch will be connecting the analog input to the ramp generator circuit. • Modification of both the area and the trench method and utilizes certain technique of both 25. At the start of conversion a voltage-to-current converter is switched to the integrator, causing it to ramp up a slope which is proportional to Vin. Explore thousands of free applications across science, mathematics, engineering, technology, business, art, finance, social sciences, and more. In the first method, the ADC runs continuously and interrupts the processor whenever a conversion result is available; the processor then has a defined time to read the result and act on it, before the next result appears. For faster analogue-to-digital conversion, the ‘successive’ or ‘counter’ type are generally employed. What is the significance of the name dual slope method? Although the actual saturation voltage of Q1 may be a few millivolts, let us assume it is truly 0 volts for simplicity. This is just one of many examples of electronic system design where good overall performance is obtained at a reasonable cost by eliminating sources of error. Charles J. Fraser, ... (Sections 3.5.1–3.5.8), in Mechanical Engineer's Reference Book (Twelfth Edition), 1994. Figure 6-82:. FIGURE 8.15. “If the slope begins with a sharp edge, the boom and bucket may be lowered over the side to control the machine and prevent a quick tip over the edge,” says Lumpkins. But it is hard to work with. Slug catchers may be either of the vessel or of the manifold pipe type. This type is simple in design and maintenance. Be aware of the pavement cross slope, wind conditions and other considerations for the route. Sanitary sewer lines are usually installed at a 2% slope so that the water doesn't outrun the solids resulting in a clogged sewer line. The slope of the edge of pavement relative to the axis of rotation is referred to as “the relative The slope of the negative ramp is determined by VREF. a) no effect The maximum recommended slope of ramps is 1:20. Flash: in which the conversion is performed almost instantaneously by a parallel group of comparators fed from a resistive ladder network voltage divider, which provides each comparator with a reference spaced one least significant bit from the next. An answer to this calibration drift dilemma is found in a design variation called the dual-slope converter. In such cases the high accuracy that can be achieved with this approach is of primary importance. d) it has two outputs This is the purpose of transistor Q1—as long as it is saturated, capacitor C cannot accumulate a charge. During this interval the counter is again allowed to run up from zero. In a properly designed triple-slope converter, a significant increase in speed can be achieved while retaining the inherent linearity, differential linearity, and stability characteristics associated with dual-slope ADCs. b) ten The slope must be graded to a maximum of no more than a one foot vertical rise for every 1.5 feet of horizontal distance. or 2-in. Analog Devices has a patented improvement on the basic dual-slope converter called Quad-Slope conversion. One step that can be taken to speed up the process is to use a triple-ramp approach. Since time t2 is dependent on the value of analog input voltage, the number of counts registered in the counter will also be a function of the analog input voltage. 1250.02 Roadway Cross Slope 1250.02(1) Lanes The cross slope on tangents and curves is a main element in roadway design. For a mild slope, such as the 1-in-20 slope required for a wheelchair ramp, a 3-in. The voltage reached at the end of the first phase of integration VI is given by. 2.6 Dual Slope A/D Converter A popular method for converting an analog voltage into a digital value is the dualslope method. the capacitor voltage is zero). We will compute the current through the capacitor at several times. Michael J. Demler, in High-Speed Analog-to-Digital Conversion, 1991. Figure 5. where N is the number of pulses counted and fclock is the clock frequency. Sanfoundry Global Education & Learning Series – Electrical Measurements. Separation of gas and liquid phases is achieved in the first section of the fingers. This is followed by the first phase of integration when the input is integrated for a predetermined, set timetin. We can divide spectroscopy into two broad classes of techniques. Integreting ADC's, using ramp or slope techniques, perform an indi-rect conversion, by first converting the signal to a function of time, and then converting from the time function to a digital number using a counter. The heart of the circuit is an op amp, linear ramp generator circuit. Then a known reference voltage of opposite polarity is applied to the integrator and is allowed to ramp until the integrator output returns to zero (the run-down period). In the second phase, a reference voltage is integrated until the output of the integrator is returned to zero. View Answer, 2. We covered some aspects of A-D conversion in Section 6.2.1. The time taken for the discharge process is recorded using a digital counter. The Americans with Disabilities Act (ADA) sets and enforces regulations with design criteria such as the slope of parking lots, sidewalks, and ramps. Figure 2. The slope of the ramp is given by the basic capacitor charge equation: For the present case, the slope of the ramp across C is computed as. Note that it has been assumed that all liquids (condensate and water) are collected and sent to an inlet three-phase separator, although it is possible to separate condensate and water at the fingers directly. Dual slope A–D converters can provide 10−18 bits of resolution. Therefore, slug sizing results should always be treated with caution, and slug catchers should be designed with an ample design margin (Burke and Kashou, 1996; Xiao and Shoup, 1998). Explanation: During the process of integration, noise is canceled out by the positive and negative ramps in the dual slope method. Resistor R2 will have 0 volts on both ends, which means it has no current flow through it. Pipe-type slug catchers are frequently less expensive than vessel-type slug catchers of the same capacity due to thinner wall requirements of smaller pipe diameter. We hypothesized that α and β band suppression will be greatest for stair walking followed by ramp walking. Sheet draining is the least preferred grading method because water must travel the furthest distance across the skin. At t<0, S 1 is set to ground, S 2 is closed, and counter=0. ... 3.4 Slope . q Zone one – cellular confinement methods (Table 1, p. 5), with a control section adjacent to the test sections. When the floating triangle signal is equal to the analog, input signal, a comparator generates and output which is sensed by the microcontroller. Dual-slope integration. If high resolution is desired, then the dual slope conversion technique can be employed. The minimum width should be 0.90 m. 3.4 Slope . Figure shows a block diagram of the basic dual-slope converter. So, this process is normally reserved for high resolution, low sampling frequency ADCs. b) charging effect As I'm sure you know, the slope of the ramp affects how the trucks will "seat" against the dock door. There are several different techniques for taking an analogue signal and creating a series of digital words from it, which you will select based on the desired speed and resolution, as well as cost. The deep roots of these plants bind the earth together while their foliage and branches protect from the erosion caused by rainfall and winds. The common methods for the analysis of a slope’s stability are Culmann Method, Ordinary Method of Slices and Bishop Method of Slices. The major elements comprising a dual-slope ADC are illustrated in Figure 3.17. It is designed such that the charging current for capacitor C will always be constant. a constant slope). Meanwhile, the reference current causes the integrator to ramp down at a slope which is proportional to Vref (i.e. When the ramp gradient increased, the L4/5 compression forces increased in both pushing and pulling (p < 0.001) Shear forces increased in pulling and decreased in pushing in all tasks. Noise present on the input voltage is reduced by averaging. One counter can be used at higher speed for the coarse conversion to determine the MSBs, crossing over to a slower speed counter for the fine resolution required in the LSBs. In the first phase a feedback loop is closed around the analog signal path while the input is set to zero. Maybe you're wanting to figure the slope of a drive way, a sanitary sewer pipe, a parking lot, a handicap accessible ramp, or maybe even the slope of a ditch. c) 500 Some applications wish to measure the time interval between two events rather than some notion of an absolute time. Various materials are used depending on the desired or necessary characteristics of your site. In the second phase of conversion the analog signal is switched to the input of an integrator while the counter, which is cleared in the autozero phase, is allowed to count up to full scale. Eventually, the decreasing ramp will pass through 0 volts, causing the comparator to switch states and disabling the counter. View Answer, 8. Three-dimensional rendering of finger-type slug catcher. So, though you don't plan to use a dock leveler, you should use dock bumpers. d) maximum noise Because the slug catcher is the first element in the gas processing plant, determining its proper size is vital to the operation of the entire plant. For the dual-slope A/D, quantization of the input signal proceeds in three phases. b) it integrates the input twice Fortunately this situation does not preclude the use of laser grading: enter the dual-slope laser.

The major elements comprising a dual-slope ADC are illustrated in Figure 3.17. Shell DEP 31.40.10.12-Gen (1998) specifies requirements and gives recommendations for the design of multiple-pipe slug catchers. Complete dual-slope converter systems are available in integrated form. For alterations (when the curb ramp was altered after January 26, 1991), the slope must not exceed 10 percent for a 6-inch rise or 12.5 percent for a 3-inch rise. Figure 3.18. b) partial noise View Answer, 6. Since the charge gained is proportional to VIN × T, and the equal amount of charge lost is proportional to VREF × tx, then the number of counts relative to the full-scale count is proportional to tx/T, or VIN/VREF. A slope increases the risk of the lawn tractor, or riding mower, tipping -- either to one side or end-over-end. slump. Recall that the input voltage to the ramp circuit determines the slope of the ramp. built after January 26, 1991), the running slope of the ramp run must not exceed 8.33 percent. As the counter counts up, the capacitor voltage (and the op amp output) will be linearly ramping up in a positive direction. Slug catchers are used at the terminus of large gas–condensate transmission pipelines to catch large slugs of liquid in pipelines, to hold these slugs temporarily, and then to allow them to follow into downstream equipment and facilities at a rate at which the liquid can be properly handled. During normal operations, the normal liquid level is kept at around the top of the riser from each finger into the main liquid collection header, which is equivalent to approximately 5 min operation of the condensate stabilization units at maximum capacity. The high degree of accuracy in the quantization process results because, at least in this ideal case, the digital output is directly proportional to the integrated input signal. Adjust speed to avoid casting snow over bridges or overpasses or too far onto sidewalks. This action will continue until the counter reaches one-half of its maximum count. • Control of inflowing water from hill side slopes is a critical factor in design of such landfills. d) voltage becomes zero with clock input The increase in conversion speed is achieved by accomplishing the reference integration (ramp-down) at two distinct rates: a high speed rate, and a “vernier” lower speed rate. When the comparator input reaches the autozeroed level, where the conversion began, its output switches off the clock to the counter and terminates the conversion. Only needs an integrator, comparator, reference, and a few analogue switches, the rest of the work can be done by the processor. A column-parallel dual-gain single-slope ADC comprises an input for receiving a signal V in, a sample-and-hold stage which receives V in and outputs sampled signal V in,samp, a comparator, a counter, and a ramp generator which generates high-gain (HG) and low-gain (LG) ramps, with the ratio of the LG ramp slope to the HG ramp slope being greater than 1. Linearity is very good and extremely high-resolution measurements can be obtained. Ohm's Law tells us that resistor R1 will have a current of. At the instant of switching the integrator output voltage is proportional to Vin, a counter is enabled and counting begins at a rate set by the internal clock. A basic dual-slope analog-to-digital converter circuit. mode control methods, and the most popular method is fixed-frequency peak-current-mode control with fixed-slope compensation ramp. Errors caused by bias currents and the offset voltages of the integrating amplifier and the comparator as well as gain errors can be canceled by using additional charge/discharge cycles to measure “zero” and “full-scale” and using the results to digitally correct the initial measurement, as in the quad-slope architecture. A spectroscopic measurement is possible only if the photon’s interaction with the sample leads to a change in one or more of these characteristic properties. Now, since 2.5 milliamperes of current is flowing through R1, but no current flows to the op amp or through R2, we can apply Kirchhoff's Current Law to conclude that the entire 2.5 milliamperes must be flowing into capacitor C as a charging current. However, vendors should be requested to provide detailed design guidelines. Ramp slopes between 1:16 and 1:20 are preferred. Working. View Answer, 5. The maximum recommended slope of ramps is 1:20. b) capacitance Peter Wilson, in The Circuit Designer's Companion (Fourth Edition), 2017. Ramp Slope Calculators for Motorcycles, Mobility Scooters, Lawnmowers & More! The value of the capacitor and conversion clock do not affect conversion accuracy, since they act equivalently on the up-slope and down-slope. In either case, the slope of the ramp is determined by the charging current of C, which is determined by the value of input voltage. Disadvantages. A simplified diagram is shown in Figure 6-80, and the integrator output waveforms are shown in Figure 6-81. If liquidity is tight, rates will go up, and if it’s loose, rates would go down or stay flat. A microcontroller generates the pulse width modulated digital signal which is converted into a floating triangle. Sheet draining is the least preferred grading method because water must travel the furthest distance across the skin. Ramp up Tv is directly proportional to the counter output and with Tmax, Tv and Tref all known, the input voltage, Tin, is determined by proportion. • Waste is placed along the sides of existing hill slope. A dual-slope ADC (DS-ADC) integrates an unknown input voltage (V IN) for a fixed amount of time (T INT), then "de-integrates" (T DEINT) using a known reference voltage (V REF) for a variable amount of time. In this study we seek to identify the neural dynamics of over-ground walking on level ground, ramps, and stairs using non-invasive mobile brain-body imaging (MoBI) EEG devices. Vegetative stabilization methods are preferred on flatter slopes and that the use of stone rip-rap should generally be limited to slopes greater than one vertical to three horizontal, where vegetative stabilization methods are not as effective. D.I. This section comprises of a change in elevation between the gas risers and the storage section that allows a clear distinction between liquid and gas phases. More specifically, if the MSB is low, then the switch will connect the analog input to the ramp generator. But since the charging and discharging processes are done through the same capacitor, the net effect of this capacitance variation is negligible. ADC output can be sent over long distances. The accuracy of the conversion only depends on the accuracy of the reference voltage. We know that negligible current flows in or out of the (+) terminal of the op amp. drain water away from the roadway and 2% is a commonly used slope rate. b) multiple of the input Integrator voltage variation, From this figure it can be seen that there are two similar triangles such that. The length of this section will promote a stratified flow pattern and permit primary separation to occur. But now they will either fly up and down. To understand the operation of the ramp generator circuit, let us assume that the capacitor is initially discharged (i.e., 0 volts). The fixed input signal integration period results in rejection of noise frequencies on the analog input that have periods that are equal to or a sub-multiple of the integration time T. Proper choice of T can therefore result in excellent rejection of 50 Hz or 60 Hz line ripple as shown in Figure 6-82. slump will work. Dual-slope ADC integrator output waveforms. Ramp Method • Used in the case of flat or slightly undulating areas. Similar principles apply to digital inputs. The most widely used integrating ADC is called a dual slope converter, a considerable improvement over the earlier single-slope version. A counter determines the time to complete the process, and the count is the digital conversion value. © 2011-2021 Sanfoundry. The dual slope A–D converter: (a) the schematic diagram; (b) the variation of the integrator output voltage during a cycle of conversion. The manifold nature of multiple pipe-type slug catchers also makes possible the later addition of additional capacity by laying more parallel pipes. With a negative input voltage applied to the ramp generator, the capacitor will begin to discharge. The installation of a trafficable solids trap is common practice and may be a preferred option when yard flood washing systems are used. If the MSB of the counter is high, then the switch connects the negative reference voltage to the ramp generator input. An analog-to-digital converter utilizing pulse width modulation and ramp and count techniques. These ADC's are suitable for use in digital voltmeters and those applications in which a relatively long time may be taken for conversion. The gas then exits the top of the slug catcher and flows to the plant inlet separator via a pressure control valve, which reduces the pressure of the gas, and further condenses water and some of the heavier hydrocarbons. large errors possible due to noises. What is the effect of clock on the voltage? What is the counter value at the beginning? That limits how often a measurement can be made (dead time). Push snow away from traffic lanes whenever possible to make sure there is no impede of the traffic flow. or 2-in. All Rights Reserved. A flat curve and an inverted curve would imply falling short rates. But the yield premium that a long term bond commands should increase to make the curve upward slope soon. Dual slope conversion is very much preferred in precise digital multi-meters, and also in 10-bit to 18-bit conversion modules. A lower input voltage (VC2) charges C to a lower voltage during the fixed time period t1, so the discharge time (t3) is shorter and the counter will have a smaller count. They are commonly used in digital voltmeters (DVMs) where their resolution is measured in display digits (4-1/2 digits = ±19999 counts or approximately 15 bits). If you aren’t sure, just describe the job to the concrete dispatcher, and they will tell you what slump to use. A key element of the dual slope ADC is a capacitor. In electronic instrumentation and signal processing, a time to digital converter (TDC) is a device for recognizing events and providing a digital representation of the time they occurred. This set of Electrical Measurements & Measuring Instruments Multiple Choice Questions & Answers (MCQs) focuses on “Dual Slope Integrating Type DVM”. High-resolution conversion can be achieved by simply using a more accurate counter, which is relatively easy to implement. slump. Dual-slope integration has many advantages. View Answer, 3. What is the output voltage in a dual slope integrating type DVM? • Control of inflowing water from hill side slopes is a critical factor in design of such landfills. View Answer. Frequency response of integrating ADC. For a mild slope, such as the 1-in-20 slope required for a wheelchair ramp, a 3-in. Liquid header collecting liquid from each finger. These methods are developed on the assumption that the plane of failure is circular arc, apart from the Culmann method that assumes a plane surface of failure through the toe of the slope. ATV, UTV, and Golf Cart Products Learn how to easily and safely load your golf cart, ATV, or UTV into the back of your truck or trailer using our golf, ATV, or UTV ramps. At the same time, the counter is again counting from zero. The converter is initialized by setting the output of the integrator, the voltage across the capacitor, to zero. The trigger slope, as the name indicates, determines whether the time-base sweep is triggered on a positive or negative going edge or slope. Often used for audio applications for this reason and because of its good match with digital signal processing architectures. d) zero slump will work. Slope-Area Method . The integration of this DC reference voltage will cause the integrator output to decrease linearly, as in the ramp shown in Fig. The selection of components for the integrator and oscillator in a dual slope converter is much less critical than for the single-slope unit. VC1 is the result of a higher input voltage. Typically used for video conversion and digital oscilloscopes. Let us examine the circuit at one more point. Hybrids of these methods are also possible, for instance, a combination of flash and successive approximation, to achieve both faster speeds and higher resolution. The control circuit provides the overall timing of circuit operation. 2. The number of clock cycles doubles with each additional bit of resolution. Suppose we let capacitor C accumulate a charge of 4 volts. Good question Lets start with the method of double integration. Over 15% and the grade is too steep for many vehicles to pull the boat and trailer out of the water. The invention is particularly useful for ramping magnetic recording bias or erase signals by providing a relatively slow slope within the non-linear region of the magnetic medium characteristic while providing a relatively steep slope in the linear region to reduce recording of disturbing "pop" signals. Its main disadvantage is a slow conversion rate, often in the range of 10 samples/second. For steeper slopes, you will have to go to a 1-in.
