Yes, this is not a joke. It was hard to believe at first, but this is an absolute fact. This is due to the Electronic Communications Protection Act (ECPA) of 1986, which is why large companies and privacy advocates have made this law a legislative priority. Federal judge Stephen Smith conducted his own research on this issue. According to his findings, in 2006, according to ECPA, there were 30,000 sealed surveillance orders nationwide. Although all these electronic surveillance commands are unsealed (in fact, most commands are still unsealed), we cannot say that this is good. Conversely, any electronic surveillance order will be unsealed only if someone commits a crime. If there is no crime, then the order will remain closed and monitoring may continue. Whether it’s access to emails, Internet activities like social networks or browser history, thousands of innocent people don’t even suspect that they are being monitored every day, cell phone tracking, eavesdropping, etc., and the jammer is not very good Solved this problem?
You may already know that the home pigeons can fly a long distance, but there are other animals, such as lobsters, that can complete with the local. Studies have shown that these marine organisms can retrieve position information from azimuth clues caused by many local anomalies in the earth’s magnetic field. With a compass built into all Android and iPhone devices, a group of engineers at the University of Oulu, Finland, recently developed a new indoor positioning technology or Bluetooth tag that does not require Wi-Fi hotspots, but it uses A specific signal processing technique discovered an interesting thing: the large amount of steel inside the building distorted the magnetic field of our planet, so each location in the building produced a unique model. Project manager Janne Haverinen explained: “Every building, its floor and corridors will generate specific portable jammer in the magnetic field. This interference can be measured to easily identify this location and generate interesting maps.”
Last year, law enforcement agencies in the United States made more than 1.3 million phone registration requests to mobile phone company customers. In addition, based on information collected by Congress ’investigations on cell phone surveillance, these requirements are increasing. On behalf of Edward Markey (Edward Markey) on Monday released the data of nine wireless operators. It shows the number of all mobile phone record requests made in 2011, but there is also a part of the phone record blocked by the jammer. Law enforcement agencies and companies do not need to report these requests, thus conducting the process of investigation and dissemination of data accounting. Massachusetts Democrat Edward Markey sent a letter to nine mobile operators last month asking them to provide data on the number and scope of these requests. In April. The companies that responded to Markey’s survey are: American Cellular Phone Company, TracFone, Cricket Communications, C Spire Wireless, MetroPCS Communications, T-Mobile America, Sprint Nextel, AT & T, and Verizon Wireless.
Robot technology is one of the cornerstones of modern technological development and global progress. In this field, not only amateurs, but also professionals, have many innovative ideas and enthusiasts. One of them is the famous iRobot company, which has made many cool robots, such as iRobot Warrior or iRobot Roomba. Therefore, IEEE visited the video of its headquarters and found a lot of interesting information about iRobot robot technology and development. These robots can be autonomous or remotely controlled, but there must be some methods to restrain them, such as jammers, jamming equipment, etc. They also have many different skills and characteristics. For example, many robots were created under the inspiration of nature. They have a crab shape and can move on different terrain to suit the surface. Or there is a worm-like iRobot that can operate inside the rig, move in narrow places and reach places where humans cannot enter.
