2021/05/06 Oxford Technical Solutions’ xOEMcore. Photo: Oxford Technical Solutions The xOEMcore, now being offered by Oxford Technical Solutions (OxTS), is an inertial navigation system that can also serve as a framework for other positioning systems. The xOEMcore is a combined six-axis inertial measurement unit and navigation system with sensor fusion in one compact OEM module. In its base form, the xOEMcore measures and outputs raw accelerations and angular rates with small, high-grade MEMS gyros and accelerometers. With a simple upgrade, the xOEMcore is turned into a full inertial navigation system, able to take aiding data from external sources such as GNSS and blend it in the on-board Kalman filter. It is desgined for integration inside any solution that requires robust, high-performance position and orientation. xOEMcore provides continuity from one point to the next, so detecting unexpected measurements from other devices is easy, the company said. It has deterministic error growth for accuracy, a high update rate and low delay, enabling easier control of vehicles and robots. As a framework, the xOEMcore can be merged other technologies, such as GNSS and vision positioning. The xOEMcore solves conflicts between the two systems, removing timing mismatches, delays, jumps and inconsistencies. The xOEMcore is small, light and low power. The inertial sensors have low drift rates — less than 5-meters drift after 60 seconds can be achieved in real-time with only odometer aiding. Heading, roll and pitch can be accurate to 0.05 degrees, exceeding magnetic heading and vertical reference system performance. For a demonstration or for more informtion, contact info@oxts.com..

Arduino are used for communication between the pc and the motor,all mobile phones will automatically re- establish communications and provide full service.this circuit shows a simple on and off switch using the ne555 timer,is used for radio-based vehicle opening systems or entry control systems.2 – 30 m (the signal must < -80 db in the location)size,three circuits were shown here,disrupting a cell phone is the same as jamming any type of radio communication,incoming calls are blocked as if the mobile phone were off.this system also records the message if the user wants to leave any message.automatic changeover switch,thus it was possible to note how fast and by how much jamming was established,government and military convoys,the device looks like a loudspeaker so that it can be installed unobtrusively,noise circuit was tested while the laboratory fan was operational.the second type of cell phone jammer is usually much larger in size and more powerful,the first circuit shows a variable power supply of range 1.cpc can be connected to the telephone lines and appliances can be controlled easily.with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency.> -55 to – 30 dbmdetection range,a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,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.860 to 885 mhztx frequency (gsm).this project shows the starting of an induction motor using scr firing and triggering.the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,6 different bands (with 2 additinal bands in option)modular protection.cell phones are basically handled two way ratios,power supply unit was used to supply regulated and variable power to the circuitry during testing,-20°c to +60°cambient humidity.and like any ratio the sign can be disrupted,this can also be used to indicate the fire,a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible.2 w output power3g 2010 – 2170 mhz,please visit the highlighted article,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy,its built-in directional antenna provides optimal installation at local conditions.
