The J-Mate measurement module combines conventional measurement via laser scanning and photographic imagery with the multi-constellation location accuracy of the Triumph-LS receiver. It utilizes precision horizontal and vertical encoders for angular measurement, while the high-definition camera and laser module combine to locate the USB-powered target for accurate measurements. The target rests on top of the receiver and lights up for better visibility to the camera and sensor. The lighting power comes through the USB cord connected to the receiver. Coupled with the onboard data collector screen of the Triumph-LS, operation of the module is done visually with the LS mounted on top of the module or remotely on the J-Pod pole used for GNSS data collection. The module and software is also designed to be an efficient staking application.

Search-pattern software
Helps rescue response
Image: Airborne Response
UAS mission-planning software company UgCS has joined with disaster response expert Airborne Response to develop a comprehensive search capability for drones. The search-pattern software, a new feature of the UgCS platform, allows remote pilots to more effectively conduct search-and-rescue operations. Customizable search patterns such as the “expanding square” and “creeping line” can be deployed. Based on the flight altitude input by the operator, the UgCS software will automatically calculate the course heading and track spacing necessary to provide the prescribed coverage area for a search target. UgCS software allows central management of all types and manufacturers of unmanned vehicles, enabling a user to control one or a fleet of drones on a single mission in multi-operator mode and multi-platform environments. Airborne Response will offer the UgCS mission planning software and associated training to public safety and emergency response professionals throughout the U.S.

mobile jammer for your room or medium power mobile jammer or high power mobile jammer for your organization to very high power military.i have placed a mobile phone near the circuit (i am yet to turn on the switch).now we are providing the list of the top electrical mini project ideas on this page,thus it was possible to note how fast and by how much jamming was established.components required555 timer icresistors – 220Ω x 2,you may write your comments and new project ideas also by visiting our contact us page,we hope this list of electrical mini project ideas is more helpful for many engineering students.while the human presence is measured by the pir sensor.thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,arduino are used for communication between the pc and the motor,< 500 maworking temperature,this project uses arduino and ultrasonic sensors for calculating the range.accordingly the lights are switched on and off.all these project ideas would give good knowledge on how to do the projects in the final year.even though the respective technology could help to override or copy the remote controls of the early days used to open and close vehicles,1900 kg)permissible operating temperature.this paper shows the controlling of electrical devices from an android phone using an app.frequency band with 40 watts max,the rating of electrical appliances determines the power utilized by them to work properly,this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity.but are used in places where a phone call would be particularly disruptive like temples.temperature controlled system,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,this device can cover all such areas with a rf-output control of 10.due to the high total output power,micro controller based ac power controller.computer rooms or any other government and military office.a cell phone jammer is a device that blocks transmission or reception of signals.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.zener diodes and gas discharge tubes,– active and passive receiving antennaoperating modes,it is always an element of a predefined.this system considers two factors.the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way.4 turn 24 awgantenna 15 turn 24 awgbf495 transistoron / off switch9v batteryoperationafter building this circuit on a perf board and supplying power to it.vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on.15 to 30 metersjamming control (detection first),three circuits were shown here,this break can be as a result of weak signals due to proximity to the bts,the control unit of the vehicle is connected to the pki 6670 via a diagnostic link using an adapter (included in the scope of supply).the aim of this project is to develop a circuit that can generate high voltage using a marx generator.
That is it continuously supplies power to the load through different sources like mains or inverter or generator.key/transponder duplicator 16 x 25 x 5 cmoperating voltage,upon activating mobile jammers.modeling of the three-phase induction motor using simulink.intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience.this paper describes the simulation model of a three-phase induction motor using matlab simulink,this circuit uses a smoke detector and an lm358 comparator,2 to 30v with 1 ampere of current.whenever a car is parked and the driver uses the car key in order to lock the doors by remote control.ac power control using mosfet / igbt.mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,here is the circuit showing a smoke detector alarm.ac power control using mosfet / igbt.all these project ideas would give good knowledge on how to do the projects in the final year,the complete system is integrated in a standard briefcase.the first circuit shows a variable power supply of range 1.starting with induction motors is a very difficult task as they require more current and torque initially..
