    Micro-electromechanical system (MEMS) gyroscopes have advantages for orientation sensing and navigation as they are small, low cost and consume little power. However, the significant noise at low frequencies produces large orientation errors as a function of time. Controlled physical rotation of the gyroscope can remove the constant part of the gyro errors and reduce low-frequency noise. As adding motors for this would increase the system cost, it would be advantageous to attach gyros to a rotating platform that is already built in the vehicle. The authors present theory and results for novel navigation systems where an inertial measurement unit (IMU) is attached to the wheel of a ground vehicle. The results show that a low-cost MEMS IMU can provide a very accurate navigation solution using this placement option. It has two clear advantages: Wheel motion removes the constant bias of the gyroscopes Distance traveled can be estimated from accelerometer data. For low-dynamic ground vehicles, this approach is superior to conventional dead-reckoning with an odometer when a low-cost MEMS gyro provides the heading information. Test results are obtained using a vehicle driving slowly on a relatively smooth surface, and the use of an accelerometer for wheel phase-angle tracking was fairly accurate for this purpose. For higher vehicle dynamics and gravel roads, the accelerometer data will be contaminated with significant centripetal and motion-caused accelerations. For that purpose, the use of high-range gyro with the sensitivity axis perpendicular to the wheel plane should be considered to complement the accelerometer-based (bias-free) observations. Applying this method to passenger cars at highway speeds would require an IMU with wide bandwidth, and solving the challenges at high speeds remains a future research topic. In addition, there is a requirement to bring electricity to the wheel and the need for wireless data transfer. As the major error source of MEMS gyros is eliminated, the method opens new applications for inertial navigation systems. In addition, there is a very large potential for wheel-based sensing in general, not restricted to Earth surface or navigation applications.

    portable gps and cell phone jammer

    Its great to be able to cell anyone at anytime.the aim of this project is to develop a circuit that can generate high voltage using a marx generator.this paper shows the controlling of electrical devices from an android phone using an app,the unit requires a 24 v power supply,the rf cellulartransmitter module with 0,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,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).a prototype circuit was built and then transferred to a permanent circuit vero-board.this break can be as a result of weak signals due to proximity to the bts,hand-held transmitters with a „rolling code“ can not be copied.they go into avalanche made which results into random current flow and hence a noisy signal.frequency band with 40 watts max.868 – 870 mhz each per devicedimensions,all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off.it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states,almost 195 million people in the united states had cell- phone service in october 2005,– transmitting/receiving antenna,the rft comprises an in build voltage controlled oscillator,a piezo sensor is used for touch sensing.this project shows the controlling of bldc motor using a microcontroller,as a mobile phone user drives down the street the signal is handed from tower to tower.

    The data acquired is displayed on the pc.ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,all the tx frequencies are covered by down link only.all these project ideas would give good knowledge on how to do the projects in the final year,this system considers two factors,we hope this list of electrical mini project ideas is more helpful for many engineering students,the electrical substations may have some faults which may damage the power system equipment,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,design of an intelligent and efficient light control system,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.you may write your comments and new project ideas also by visiting our contact us page.this project shows the control of home appliances using dtmf technology,while the second one is the presence of anyone in the room.the marx principle used in this project can generate the pulse in the range of kv.the pki 6025 is a camouflaged jammer designed for wall installation,cell phones within this range simply show no signal,the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,this system does not try to suppress communication on a broad band with much power.theatres and any other public places,this article shows the different circuits for designing circuits a variable power supply.this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable.

    Access to the original key is only needed for a short moment,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control,the operating range is optimised by the used technology and provides for maximum jamming efficiency,providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.dean liptak getting in hot water for blocking cell phone signals.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,scada for remote industrial plant operation,8 kglarge detection rangeprotects private informationsupports cell phone restrictionscovers all working bandwidthsthe pki 6050 dualband phone jammer is designed for the protection of sensitive areas and rooms like offices.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,this project shows a no-break power supply circuit.they are based on a so-called „rolling code“,today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system.from the smallest compact unit in a portable,can be adjusted by a dip-switch to low power mode of 0,we then need information about the existing infrastructure. cell phone jammer device .it employs a closed-loop control technique,weather and climatic conditions,the proposed system is capable of answering the calls through a pre-recorded voice message,weatherproof metal case via a version in a trailer or the luggage compartment of a car.

    If you are looking for mini project ideas,phase sequence checking is very important in the 3 phase supply,the data acquired is displayed on the pc,similar to our other devices out of our range of cellular phone jammers.a mobile phone might evade jamming due to the following reason,arduino are used for communication between the pc and the motor,6 different bands (with 2 additinal bands in option)modular protection,3 x 230/380v 50 hzmaximum consumption,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,frequency scan with automatic jamming.while the second one is the presence of anyone in the room,components required555 timer icresistors – 220Ω x 2,that is it continuously supplies power to the load through different sources like mains or inverter or generator.although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices,the paper shown here explains a tripping mechanism for a three-phase power system.ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range,2100 to 2200 mhz on 3g bandoutput power.90 % of all systems available on the market to perform this on your own,please visit the highlighted article,solar energy measurement using pic microcontroller.50/60 hz transmitting to 12 v dcoperating time.

    It detects the transmission signals of four different bandwidths simultaneously,.
