Apple's new patent: let your iPhone send out a distress signal even when there is no signal


According to a report on January 9, according to foreign media reports, Apple has applied for a new patent. Even when the iPhone has no mobile phone signal, it can still send emergency distress signals in other ways until the rescue team comes.


Apple's new patent: let your iPhone send out a distress signal even when there is no signal


It is reported that Apple's latest patent application in the US Patent and Trademark Office shows that iPhone or iPad can be turned into a distress device at critical times, especially in areas without cellular network service coverage, which can turn the device into a UE device, in other words , The user can send a broadcast emergency distress signal through the device (using the broadcast channel base station in his area).


In addition, if there is no broadcast channel base station in the area, these UE devices can even actively connect to those wireless networks and actively access them, so as to insert emergency distress signals.


It is worth mentioning that if your device has the distress function turned on, then there is a super battery life saving mode to choose from, which can help you delay the device's battery life to the maximum extent until you are successfully rescued.


Of course, Apple also mentioned in the patent application that if it is not the case that the device has a particularly low battery, it is still not recommended that the user manually turn on the emergency power saving mode, because after turning on this feature, your device only retains the most basic RF signals. At the same time, the screen is also turned off. In short, all useless power is turned off.


Compared to the software's help function, the above-mentioned patents applied by Apple are more adaptable to the environment and more effective. In the future, they are likely to be equipped with these functions as standard on iOS terminals such as iPhone and iPad.
