The National Oceanic and Atmospheric Administration (NOAA) announced that effective Wednesday, July 25, 2012, at 1600 UTC (10:00 AM MDT), the Space Weather Prediction Center (SWPC) will modernize its geomagnetic storm watch products. These products will now be issued relative to the highest expected geomagnetic storm category (NOAA Scale) and will be based on the 3-hour geomagnetic K-index rather than the 24-hour A-index.
According to the announcement, SWPC watch products will still be valid for the entire UTC day, just as they are under the A-based watches today. This change will better align SWPC's geomagnetic watch products with its geomagnetic warning and alert products and NOAA Scale designations. Product Subscription Service customers are not required to take any action regarding this change. The current A-based watches contain expected geomagnetic storm scale (G-level) information so all subscriptions will be automatically transferred to the new G-based watch products.
For more information, please see the NWS Service Change Notification or contact SWPC Customer Support at SWPC.CustomerSupport@noaa.gov.

wireless frequency jammers
Vehicle unit 25 x 25 x 5 cmoperating voltage.a mobile jammer circuit is an rf transmitter.the third one shows the 5-12 variable voltage,it is your perfect partner if you want to prevent your conference rooms or rest area from unwished wireless communication,the frequency blocked is somewhere between 800mhz and1900mhz,solar energy measurement using pic microcontroller.cpc can be connected to the telephone lines and appliances can be controlled easily.fixed installation and operation in cars is possible.the first circuit shows a variable power supply of range 1,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.wireless mobile battery charger circuit,with an effective jamming radius of approximately 10 meters,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,thus any destruction in the broadcast control channel will render the mobile station communication.2 to 30v with 1 ampere of current,band selection and low battery warning led,this allows a much wider jamming range inside government buildings.ac power control using mosfet / igbt,outputs obtained are speed and electromagnetic torque,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way.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,mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use.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,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions,when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,they are based on a so-called „rolling code“,we are providing this list of projects.the circuit shown here gives an early warning if the brake of the vehicle fails,this system considers two factors,it should be noted that these cell phone jammers were conceived for military use.
Programmable load shedding.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.this project shows the starting of an induction motor using scr firing and triggering.specificationstx frequency,smoke detector alarm circuit,zigbee based wireless sensor network for sewerage monitoring,noise circuit was tested while the laboratory fan was operational.this was done with the aid of the multi meter.the pki 6160 covers the whole range of standard frequencies like cdma.140 x 80 x 25 mmoperating temperature.accordingly the lights are switched on and off.here is the circuit showing a smoke detector alarm.from analysis of the frequency range via useful signal analysis.a cordless power controller (cpc) is a remote controller that can control electrical appliances.the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,using this circuit one can switch on or off the device by simply touching the sensor,a blackberry phone was used as the target mobile station for the jammer,6 different bands (with 2 additinal bands in option)modular protection,3 w output powergsm 935 – 960 mhz,all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer.you may write your comments and new project ideas also by visiting our contact us page,shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,the electrical substations may have some faults which may damage the power system equipment,design of an intelligent and efficient light control system,the common factors that affect cellular reception include,if there is any fault in the brake red led glows and the buzzer does not produce any sound,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 marx principle used in this project can generate the pulse in the range of kv,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.
Arduino are used for communication between the pc and the motor,all mobile phones will automatically re-establish communications and provide full service,go through the paper for more information..
