????我們通常不會報道蘋果（Apple）的專利，因為它的專利申請多如牛毛，而被公布的則少之又少。

????但我們要為20130073095號專利申請破例一次。這項專利于上周四發布，由AppleInsider的米奇?坎貝爾發現。

????這項專利描述了一個傳感器和微處理器系統。一旦這個系統探測到iPhone或iPad正在墜落，它將改變設備的重心，防止設備墜地時最易碎的部件著地。

????We don't usually write about Apple's (AAPL) patents because the company files so many and so few ever see the light of day.

????But for Patent Application No. 20130073095, published Thursday and spotted by AppleInsider's Mikey Campbell, we'll make an exception.

????It describes a sensor-and-microprocessor system that can detect when an iPhone or iPad is falling and shift the device's center of balance so that it doesn't land on its most fragile parts.
