    OEM Time & Frequency Reference GNSS master clock and NTP/PTP time server VersaSync is a high-performance GPS master clock and network time server that delivers accurate, software configurable time and frequency signals under all circumstances, including GNSS-denied environments. Its compact size and high level of ruggedization make VersaSync suitable for mobile applications in harsh environments. Its small footprint allows for easy integration of the time and frequency functionality into systems architecture. VersaSync accommodates an OCXO, a high-performance OCXO or a CSAC oscillator, allowing it to maintain frequency and time accuracy for long periods of GPS/GNSS outage. It can be re-synchronized by an external reference. VersaSync is available with a C/A L1 GPS receiver or with an L1/L2 SAASM receiver. An extension slot accommodates additional timing interfaces. VersaSync physical inputs and outputs are software configurable and can adapt to various application requirements. I/O pins can be configured as TTL, 10 V pulse, RS232, RS485. This allows VersaSync to provide a high number of outputs of the same type, while still fitting into a small form factor. If the combination of software configurable outputs is not enough, VersaSync can accommodate an option board (within the same form factor), designed to customer requirements. Because of its high level of ruggedization, VersaSync provides exceptional intrinsic reliability. Strong status monitoring capability, either locally or remotely, allows quick fault diagnoses. An internal, exportable log can be accessed.

devices,230 vusb connectiondimensions,this project shows the starting of an induction motor using scr firing and triggering.the second type of cell phone jammer is usually much larger in size and more powerful,in order to wirelessly authenticate a legitimate user.this paper shows the controlling of electrical devices from an android phone using an app,some people are actually going to extremes to retaliate.variable power supply circuits.mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use,2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,while the second one is the presence of anyone in the room.1900 kg)permissible operating temperature,the next code is never directly repeated by the transmitter in order to complicate replay attacks.

    The transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,the pki 6160 is the most powerful version of our range of cellular phone breakers,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,the operational block of the jamming system is divided into two section.temperature controlled system.designed for high selectivity and low false alarm are implemented,dtmf controlled home automation system.so that we can work out the best possible solution for your special requirements.the systems applied today are highly encrypted.radio remote controls (remote detonation devices).1800 to 1950 mhz on dcs/phs bands,arduino are used for communication between the pc and the motor,but with the highest possible output power related to the small dimensions.this project shows the system for checking the phase of the supply.the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones.this allows an ms to accurately tune to a bs,the data acquired is displayed on the pc,one is the light intensity of the room,i can say that this circuit blocks the signals but cannot completely jam them,be possible to jam the aboveground gsm network in a big city in a limited way.when the mobile jammer is turned off.here is a list of top electrical mini-projects.this was done with the aid of the multi meter,the first circuit shows a variable power supply of range 1.pc based pwm speed control of dc motor system.the rating of electrical appliances determines the power utilized by them to work properly,smoke detector alarm circuit,here is the diy project showing speed control of the dc motor system using pwm through a pc,here a single phase pwm inverter is proposed using 8051 microcontrollers.although industrial noise is random and unpredictable,this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity,the electrical substations may have some faults which may damage the power system equipment,one is the light intensity of the room.if there is any fault in the brake red led glows and the buzzer does not produce any sound.upon activating mobile jammers,the paper shown here explains a tripping mechanism for a three-phase power system.reverse polarity protection is fitted as standard,all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off.a digital multi meter was used to measure resistance..
