Prevent Fly-A-Ways check your DJI Spark Wi-Fi Interference and Sensors State
 
06:57
Today we’re going to be talking about how to check your DJI Sparks Wi-Fi Interference and Sensors State to Prevent Fly-Aways. The newest latest and greatest firmware update, and what kind of signal interference the DJI Spark can be susceptible too. If you notice I have the Spark set up here on the dresser facing me. Also I have an eero TrueMesh Wi-Fi system that offers tri-band Wi-Fi signals that cover the same spectrum as the spark we’re going to use this as interference to show what the spark can do. So whenever you go to a new flying field you’re definitely going to want to check interference. Not only IMU and Compass which you can find here in sensor state. To find sensor state you can click the 3 dots go into general settings then MC settings and scroll down to advanced settings at the bottom. From here you can see where it says sensor state. You have 4 color options that are used to show the state of the sensors. Blue- Channel In Use Green- Excellent Yellow- Good or Red- Poor It is my personal opinion that red should be labeled do not fly, but that’s just me. DJI uses this color scheme through the spark to show either signal strength or sensor state as stated previously. We’re going to go down here to Wi-Fi channels…. Pay attention to this… This is important! You have your 2.4 Ghz and your 5.8Ghz this is referencing which Wi-Fi channels you are using. The Wi-Fi channels which connect your remote control to your drone or your phone to your drone. If you notice I am using the 5.8Ghz range right now and it has available the 149, 153, 157, 161, and 165. Notice 161 and 165 are fluctuating between green and red… This is going to make me NOT use these channels its going to make me stay away from these channels. Right now I am on the 149 band. If you are ever going to change these channels you want to do it on the ground and never in flight. The Spark Disconnects while changing channels and to avoid the risk of fly away you want to be grounded. I have my propellers off on the spark right now just in case anything were to happen. So I am going to choose channel index 153 and hit apply, and you will see the channel get “busy” and settle back down once the channel change has completed. RSSI or Recieved Signal Strength Indicator is a common name for the received radio signal power level in a wireless network. It is often measured in either decibels (db), or simply numbers between 0 and 100. RSSI can be expressed as either a negative or positive value, however, in both instances smaller values closer to zero indicate a stronger signal. In this case as it relates to the spark the rssi is measuring the interference in the channels from -60 to -100 and the lower the interference is towards the -100 scale the better quality the controller is to the spark The point I’m trying to drive home is 1 be aware of your surroundings, 2 monitor your Wi-Fi channels, and 3 If you fly in a new area check double check and triple check all you sensor states and wifi channel congestions.

Remote sensing
 
26:32
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to in situ observation. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). It may be split into active remote sensing, when a signal is first emitted from aircraft or satellites) or passive (e.g. sunlight) when information is merely recorded.

"Remote sensing" is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on site observation. Remote sensing is a sub-field of geography. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth by means of propagated signals . It may be split into active remote sensing or passive when information is merely recorded. Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas. Reflected sunlight is the most common source of radiation measured by passive sensors. Examples of passive remote sensors include film photography, infrared, charge-coupled devices, and radiometers. Active collection, on the other hand, emits energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target. RADAR and LiDAR are examples of active remote sensing where the time delay between emission and return is measured, establishing the location, speed and direction of an object. Remote sensing makes it possible to collect data of dangerous or inaccessible areas. Remote sensing applications include monitoring deforestation in areas such as the Amazon Basin, glacial features in Arctic and Antarctic regions, and depth sounding of coastal and ocean depths. Military collection during the Cold War made use of stand-off collection of data about dangerous border areas. Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed.

Signals and systems-Introduction
 
05:15
In this session we will discuss what is a signals ,what is a system and applications of signals. Signal is a function of one or more variables that conveys some information. If a signal is a function of single variable it is called one dimensional. E.g Audio signal. The signal which is a function of more than one variable is known as multi-dimensional. E.g Image signal. A system is an entity that process the input signals and produces a new signal. E.g: Communication systems Signals are closely associated in our day-to-day life.Following are few examples of signal and systems: 1.)Communication system 2.) Control Systems 3.) Microelectromechanical systems 4.) Remote sensing 5.) Biomedical signal Processing 6.) Auditory systems

Understand the Active and Passive Satellites
 
01:56
Active and Passive Satellites Active and Passive Satellites are communication satellites. A communication satellite is a spacecraft that orbits the earth and relays messages, radio, telephone and television signals. Stations on ground called earth station transmit signals to the satellite and the satellite in turn relays the signal to our earth stations. The first satellite to relay messages from one earth station to another was SCORE. It was launched on December 18, 1958. Communication through satellites are either passive or active. The first communication satellites were passive. Passive Satellites nearly reflect the signal received from the earth station. In 1960, the United States launched the Echo satellite, a metallic balloon that reflected signals. Active communication satellites received signal received from earth amplify the signals and transmit hem back to earth. Now days we use only Active communication satellites.

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. Remote sensing is used in numerous fields, including geography and most Earth Science disciplines (for example, hydrology, ecology , oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications. In current usage, the term "remote sensing" generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth, including on the surface and in the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). It may be split into "active" remote sensing (i.e., when a signal is emitted by a satellite or aircraft and its reflection by the object is detected by the sensor) and "passive" remote sensing (i.e., when the reflection of sunlight is detected by the sensor). Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas. Reflected sunlight is the most common source of radiation measured by passive sensors.

Military collection during the Cold War made use of stand-off collection of data about dangerous border areas. Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed. Orbital platforms collect and transmit data from different parts of the electromagnetic spectrum, which in conjunction with larger scale aerial or ground-based sensing and analysis, provides researchers with enough information to monitor trends such as El Nino and other natural long and short term phenomena. Other uses include different areas of the earth sciences such as natural resource management, agricultural fields such as land usage and conservation, and national security and overhead, ground-based and stand-off collection on border areas.

How is LiDAR remote sensing used for Autonomous vehicles?
 
03:02
Self-driving cars are now a reality. Take a look around. Cars are already driving themselves on the roads of California, Texas, Arizona, Washington, Pennsylvania, Michigan and many more cities. Though, currently they are restricted to specific test areas and driving conditions. But how exactly do they work? Just like humans they also face issues of traffic congestion, rash driving, potholes, trees and other obstacles on the road. But again…How do they change lane, keep a safe distance from other vehicles passing by and how do they identify roadblocks. Let’s take a closer look at how they handle such situations smoothly? You might have noticed a rotating device installed on top of this autonomous vehicle. Sometimes these devices are mounted on the bonnet. This device is called LiDAR. It acts as the eye of self-driving vehicles providing a 360-degree view of its surroundings in order to enable safe driving. Continuously rotating LiDAR system sends thousands of laser pulses every second. These pulses collide with the various objects around the vehicle and reflect back the signals. These light reflections are then used to create a 3D point cloud. An onboard computer records each laser’s reflection point and translates this rapidly updating point cloud… into an animated 3D representation. #Lidar #Autonomous #gis

Types of Sensors│ Different types of sensors│ Classification of sensor│ Hi everybody, today I will share about Types of Sensor. This video you learn following about Types of Sensor. Sensors are classified based on the nature of quantity they measure. Following are the types of sensors with few examples. 1. Acoustic and sound sensors. A sensor is used to measure sense an environment and converts this information into a digital or analogue data signal that can be interpreted by a computer or observer. An acoustic wave sensor is an electronic device that can measure sound levels. For Example, Microphone, Hydrophone. 2. Automotive sensors. Automotive sensor is one of the largest sensor companies in the world, with innovative sensor solutions that help customers transform concepts into smart, connected creations. For example, Speedometer, Radar gun, Speedometer, fuel ratio meter. 3. Chemical Sensors. A chemical sensor is a device that transforms chemical information composition, presence of a particular element or ion, concentration, chemical activity, partial pressure into an analytically useful signal. For example, Ph sensor, Sensors to detect presences of different gases or liquids. 4. Electric and Magnetic Sensors. Magnetic sensors differ from most other detectors in that they do not directly measure the physical property of interest For example, Galvanometer, Hall sensor measures flux density, Metal detector. 5. Environmental Sensors. Environmental sensors include barometric pressure sensors as well as integrated environmental sensors. These integrated sensors combine barometric air pressure, humidity, ambient air temperature sensing functions as well as air quality measuring. For example, Rain gauge, snow gauge, moisture sensor. 6. Optical Sensors. Optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications, For example, Photo diode, Photo transistor, Wave front sensor. 7. Mechanical Sensors. Mechanical sensors are used for positioning and limit switch tasks on machine tools and presses, flexible production centers, robots, assembly and conveying equipment, and in machine and plant construction. For decades, they have proven their worth as the traditional strongmen of automation. For example, Strain Gauge, Potential meter measures displacement. 8. Thermal and Temperature sensors. The thermal response of a temperature sensor is the speed at which it responds to a sudden change in temperature. Thermal response time is the time taken for the sensor to react to this change in temperature. For example, Calorimeter, Thermocouple, Thermostat, Gordon gauge. 9. Proximity and Presences sensors A proximity or presences sensor is the one which is able to detect the presences of nearby objects without any physical contact. They usually emit electromagnetic radiations and detect the changes in reflected signal if any. For example, Doppler radar, Motion detector. Thanks for watching my tutorial videos.

Multivariate probability model for 3-layer remote sensing
 
20:36
We develop a multivariate probability model for a 3-layer radiative transfer equation, which can be used to predict the stochastic nature of measured signals for multispectral and hyperspectral remote sensing applications. A multivariate 3-layer model is particularly important because the remote sensing problem is typically clutter limited, meaning that variability from the scene - temporal or spatial changes in environmental parameters collectively called “clutter” - is greater than sensor noise and thus is the limiting factor in determining whether a particular target of interest can be detected. Our model is derived from physical considerations regarding expected statistics for blackbody radiation, transmission, and radiance, and is described by the Johnson system of distributions. With the model we obtain pdfs of the target radiance, background radiances, and thermal contrast, and obtain new physical insights on the remote sensing scenario.

What is DATA ACQUISITION? What does DATA ACQUISITION mean? DATA ACQUISITION meaning - DATA ACQUISITION definition - DATA ACQUISITION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS or DAQ, typically convert analog waveforms into digital values for processing. The components of data acquisition systems include: 1. Sensors, to convert physical parameters to electrical signals. 2. Signal conditioning circuitry, to convert sensor signals into a form that can be converted to digital values. 3. Analog-to-digital converters, to convert conditioned sensor signals to digital values. Data acquisition applications are usually controlled by software programs developed using various general purpose programming languages such as Assembly, BASIC, C, C++, C#, Fortran, Java, LabVIEW, Lisp, Pascal, etc. Stand-alone data acquisition systems are often called data loggers. There are also open-source software packages providing all the necessary tools to acquire data from different hardware equipment. These tools come from the scientific community where complex experiment requires fast, flexible and adaptable software. Those packages are usually custom fit but more general DAQ package like the Maximum Integrated Data Acquisition System can be easily tailored and is used in several physics experiments worldwide. In 1963, IBM produced computers which specialized in data acquisition. These include the IBM 7700 Data Acquisition System, and its successor, the IBM 1800 Data Acquisition and Control System. These expensive specialized systems were surpassed in 1974 by general purpose S-100 computers and data acquisitions cards produced by Tecmar/Scientific Solutions Inc. In 1981 IBM introduced the IBM Personal Computer and Scientific Solutions introduced the first PC data acquisition products. Data acquisition begins with the physical phenomenon or physical property to be measured. Examples of this include temperature, light intensity, gas pressure, fluid flow, and force. Regardless of the type of physical property to be measured, the physical state that is to be measured must first be transformed into a unified form that can be sampled by a data acquisition system. The task of performing such transformations falls on devices called sensors. A data acquisition system is a collection of software and hardware that lets you measure or control physical characteristics of something in the real world. A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software. A sensor, which is a type of transducer, is a device that converts a physical property into a corresponding electrical signal (e.g., strain gauge, thermistor). An acquisition system to measure different properties depends on the sensors that are suited to detect those properties. Signal conditioning may be necessary if the signal from the transducer is not suitable for the DAQ hardware being used. The signal may need to be filtered or amplified in most cases. Various other examples of signal conditioning might be bridge completion, providing current or voltage excitation to the sensor, isolation, linearization. For transmission purposes, single ended analog signals, which are more susceptible to noise can be converted to differential signals. Once digitized, the signal can be encoded to reduce and correct transmission errors.

Getting The Best Signal To Your Aftermarket Car Amplifier | Car Audio Q&A
 
04:02
In this Q&A we answer the question: 'what is the best method for getting signal to your amplifier, high level or low level inputs?' Shop Line-Out Converters: http://www.sonicelectronix.com/cat_i331_line-out-converters.html?utm_source=YouTube&utm_medium=Youtube%20Description&utm_campaign=Q%26A&utm_term=Best%20Signal Depending on the equipment in you system you will have different options available to you. If you have a factory headunit you will not have RCA (low level) outputs, so unless your aftermarket amplifier has speaker level (high level) inputs you will need to use a Line Out Converter (LOC/High-Low Adapter) to get signal to your amp. Similarly, if you have an aftermarket car stereo but it only has one set of RCA outputs you may have to use an LOC depending on what signal you are trying to get to your amplifier, or use an equalizer that gives you the required outputs. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Sonic Electronix always strives to be the premiere online shopping destination for car electronics and other consumer electronics.

Remote Sensing Laboratory Helicopter Pilots' Wildland Fire Training at the NNSS
 
01:34
Another wildland fire season is upon us, and nowhere is the threat of a wildland fire more prevalent than the Nevada National Security Site (NNSS). The 1,365 square miles of NNSS have high terrain, thick vegetation in more rugged, inaccessible areas, and a consistent threat of lightning strikes from erratic weather that highlights the summer months. It makes sense, then, that the NNSS Fire and Rescue (F&R) department would rely on the quick-responding expertise of some of our own airborne assets, namely the pilots of the Aerial Measuring program at the Remote Sensing Laboratory (RSL). When RSL pilots at Nellis Air Force Base aren’t traveling the country conducting aerial survey missions, they are on standby to assist F&R with water drops on potential fires anywhere on the NNSS. Last week, those pilots underwent extensive flight training to get ready, mastering skills in dipping water from a large bladder, or pumpkin, positioned at Desert Rock Airstrip, and dumping 144 gallons on random targets called in by first responders positioned around far corners of the runway. “The training at Desert Rock went extremely well,” says Capt. Bill Nixon, lead member of the F&R helitack crew that working with the Bell 411 helicopter, coined “Energy 11.” “The pilots are mastering new techniques for attaching and detaching the bucket, and they conducted multiple dips and drops, which included drops on slope targets.” The RSL support is part of a Memorandum of Understanding with F&R that also includes aerial observation during wildland fire events. These observation flights provide situational awareness that is necessary for effectively position resources and planning tactics. The helicopter also can be used to haul crews and equipment, dropping them in the vicinity of a fire. Early control of a wildfire avoids both expending significant resources to manage a later stage fire and also can minimize or eliminate fire damage to facilities and infrastructure. The pumpkin water drop operations can be one of the most challenging aspects of wildland fire support. Pilots must position the Bell 411 directly over the large bladder, which from the air seems quite small, dip the bucket into the water, and withdraw it straight up into the air as to not spill or topple the bucket. The pilots then fly out to a specific location as designated by firefighters on the ground. Although a real, raging fire might be visible from the air, locating a specific target for ground support can be harder. Ground crews vector in the helicopter using a radio, calling out clock-like coordinates, and requesting drops sometimes within less than 100 yards of their position. During last week’s training, pilots worked to perfection, sometimes missing their marks, but always return to give it another shot. By the end of the 3-day training cycle, all four RSL pilots were scoring direct hits with skill and precision. When the RSL aircrews participate in wildland firefighting support, they not only gain flight proficiency, but also valuable experience working within the command structure established to manage the fire emergency. Their integration into the planning, tactics, operations, and effectiveness evaluation provides actual experiences that reinforce and cement the skills learned during drills and exercise involving radiological emergency response.
