A recognition system recognizes and prevents the unlawful use of a firearm. The present invention also provides a means for tracking and tracing the history of a firearm movement and registered ownership. The recognition system may include a variety of scanning devices that may be adapted to scan for a firearm and/or may scan for a special component formed into the firearm material. The scanning devices may be made visible to people to act as a deterrent, or may be hidden in various everyday items, such as in exit signs, advertisement displays and the like. The scanning devices may not only detect firearms, but other items that may be restricted in their carry, such as knives, narcotics, explosives, or the like.
A data backup device is built into a device charging mechanism to provide automated data backup when a device is charged. Such a system results in regular data backups, as most users consistently charge their devices, such as their cell phones, smart phones, tablet computers, and the like. The charger/data backup device can integrate into a wireless network to provide remote access and additional backup options. The charger/data backup device can be configured to move data between electronic devices from multiple manufacturers or between electronic devices having different operating systems.
A listening device can be configured to receive an audio signal from a specific source. For example, the listening device may be configured to receive commentary at a sporting event or may be configured to receive audio from a television transmission. The listening device may be part of a system adapted to send the audio signal, and may also be configured to insert advertising into the audio stream where appropriate. For example, at a baseball game, the stadium may send an audio signal that with game stats, commentary and the like. Many fans may desire to receive such commentary and may, rent or buy a listening device specifically designed to receive the audio signal from the stadium. The stadium may then insert advertising in between innings, for example. This may permit the stadium to gain revenue through advertising, while also provide the fans with advertising that may be of interest.
