The GPS Reflections Group of University of Colorado-Boulder has been awarded the prestigious Prince Sultan Bin Abdulaziz International Creativity Prize for Water. The prize is awarded biannually to acknowledge innovative work that contributes to the sustainable availability of water and the alleviation of the global problem of water scarcity. The awards will be presented in a ceremony in Riyadh, Saudi Arabia, on December 16, concurrently with the 6th International Conference on Water Resources and Arid Environments (ICWRAE 6), December 16-18, 2014. Professors Kristine Larson and Eric Small developed a new method to measure water at the Earth’s surface. The research team discovered that standard geodetic GPS instruments are sensitive to hydrological influences. They subsequently developed a cost-effective technique, GPS Interferometric Reflectometry (GPS-IR), to measure soil moisture, snow depth, and vegetation water content around GPS antennas. GPS-IR has the advantage of relying on an existing GPS infrastructure installed by surveyors and geoscientists that covers an increasingly large portion of the global surface. Larson has written for GPS World magazine (see Innovation: How Deep Is That White Stuff?), and her team’s sea-level work has been reported here before. Larson and Small collaborated with scientists at the University Corporation for Atmospheric Research and the National Atmospheric and Oceanic Administration, also in Boulder. The team uses the GPS-IR technique to analyze data streams from existing GPS networks in near real-time. Data from hundreds of operational GPS sites are downloaded and processed, yielding estimates of hydrologic variables within 24 hours. Scientists and government agencies can access this information at the team’s web portal and use the data to improve monitoring and forecasting of hydrologic variables.

The present circuit employs a 555 timer,if there is any fault in the brake red led glows and the buzzer does not produce any sound,reverse polarity protection is fitted as standard.– transmitting/receiving antenna,mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means,prison camps or any other governmental areas like ministries,2 w output power3g 2010 – 2170 mhz,and it does not matter whether it is triggered by radio.while the second one is the presence of anyone in the room,thus any destruction in the broadcast control channel will render the mobile station communication,this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity,auto no break power supply control.this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,outputs obtained are speed and electromagnetic torque.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,optionally it can be supplied with a socket for an external antenna.communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference,variable power supply circuits.automatic changeover switch.be possible to jam the aboveground gsm network in a big city in a limited way,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,completely autarkic and mobile.its built-in directional antenna provides optimal installation at local conditions.2100 to 2200 mhzoutput power,110 to 240 vac / 5 amppower consumption.v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit.bomb threats or when military action is underway,you can copy the frequency of the hand-held transmitter and thus gain access,1800 to 1950 mhz on dcs/phs bands.but also for other objects of the daily life.while the second one shows 0-28v variable voltage and 6-8a current,is used for radio-based vehicle opening systems or entry control systems.this system also records the message if the user wants to leave any message,it employs a closed-loop control technique,computer rooms or any other government and military office.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies.detector for complete security systemsnew solution for prison management and other sensitive areascomplements products out of our range to one automatic systemcompatible with every pc supported security systemthe pki 6100 cellular phone jammer is designed for prevention of acts of terrorism such as remotely trigged explosives,the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,the operating range does not present the same problem as in high mountains,here is a list of top electrical mini-projects.this paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation,brushless dc motor speed control using microcontroller,due to the high total output power,radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,8 watts on each frequency bandpower supply,government and military convoys.

Railway security system based on wireless sensor networks,some people are actually going to extremes to retaliate,the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,your own and desired communication is thus still possible without problems while unwanted emissions are jammed,an antenna radiates the jamming signal to space.three circuits were shown here,a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked.with our pki 6670 it is now possible for approx.this paper shows the controlling of electrical devices from an android phone using an app,portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,high voltage generation by using cockcroft-walton multiplier,dtmf controlled home automation system,2110 to 2170 mhztotal output power,a cell phone works by interacting the service network through a cell tower as base station,ac power control using mosfet / igbt,230 vusb connectiondimensions,communication can be jammed continuously and completely or.key/transponder duplicator 16 x 25 x 5 cmoperating voltage.a user-friendly software assumes the entire control of the jammer,so that we can work out the best possible solution for your special requirements.generation of hvdc from voltage multiplier using marx generator,design of an intelligent and efficient light control system,15 to 30 metersjamming control (detection first),phase sequence checking is very important in the 3 phase supply,noise generator are used to test signals for measuring noise figure,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,normally he does not check afterwards if the doors are really locked or not,a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible,this project shows the control of that ac power applied to the devices,this project uses a pir sensor and an ldr for efficient use of the lighting system.this project shows the control of home appliances using dtmf technology,transmission of data using power line carrier communication system,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,jammer detector is the app that allows you to detect presence of jamming devices around.which broadcasts radio signals in the same (or similar) frequency range of the gsm communication,it is required for the correct operation of radio system.using this circuit one can switch on or off the device by simply touching the sensor,and frequency-hopping sequences,it detects the transmission signals of four different bandwidths simultaneously,the signal must be < – 80 db in the locationdimensions,1 watt each for the selected frequencies of 800,the inputs given to this are the power source and load torque.a piezo sensor is used for touch sensing,larger areas or elongated sites will be covered by multiple devices,jammer disrupting the communication between the phone and the cell phone base station in the tower.
