摘要： A clamshell device having a dual accelerometer detector includes a first keyboard portion including a first accelerometer, a second display portion including a second accelerometer, a hinge for coupling the first portion to the second portion, and circuitry coupled to the first and second accelerometers for providing an output signal in response to the position of the first and second portions of the clamshell device. The output signal is provided to indicate a shutdown or standby mode, tablet operation mode, a partially shut or power savings mode, a normal operating mode, or an unsafe operating mode.

摘要： In an integrated free-fall detection device for a portable apparatus an acceleration sensor generates acceleration signals correlated to the components of the acceleration of the portable apparatus along three detection axes. A dedicated purely hardware circuit connected to the acceleration sensor generates a free-fall detection signal in a continuous way and in real-time. The free-fall detection signal has a first logic value in the event that the acceleration signals are simultaneously lower than a respective acceleration threshold, and is sent to a processor unit of the portable apparatus as an interrupt signal to activate appropriate actions of protection for the portable apparatus. Preferably, the acceleration sensor and the dedicated purely hardware circuit are integrated in a single chip and the acceleration sensor is made as a MEMS.
