ST Microelectronics’ free fall detection solution prevents data damage in notebooks

Supplier News

ST Microelectronics ’ complete free-fall detection solution, which consists of a 3-axis motion sensor and software application, has been chosen to protect users’ data stored on hard-disk drives in the new ESPRIMO Mobile family of professional notebooks from Fujitsu Siemens Computers.

ST Microelectronics’ MEMS motion sensor instantly detects any abnormal movement of the PC and prompts the system to stop all reading and writing operations, and to quickly move the magnetic head on the hard-disk drive to a safe position, before the laptop hits the ground.

Security, including data protection, is one of the features in Fujitsu Siemens Computers’ new ESPRIMO Mobile series of professional notebooks. Combining a micro-machined silicon sensor with an electronic interface and system software, ST Microelectronics’ free-fall detection solution helps secure sensitive data integrity, an important aspect of mobile computing in enterprise environments.

According to Barbara D’Introno, Director Product Marketing, Fujitsu Siemens Computers, they were looking for a motion sensor that can respond immediately to any significant changes in direction, speed and acceleration. ST Microelectronics’ MEMS accelerometers represent a combination of these elements. She added that ST Microelectronics also deliver a complete turn-key solution that has significantly reduced time-to-market for advanced hard disk drive data protection.

ST Microelectronics’ sensor meets stringent drop-test criteria required in portable electronic devices. Its mechanical design provides high immunity to vibration and shock resistance up to 10,000g. The sensor provides acceleration values at a low noise level with minimised power consumption, which is critical in battery-operated portable systems, such as smart phones, PDAs and laptops.

ST Microelectronics’ MEMS motion sensors target a wide array of applications in computer peripherals, consumer, telecommunications and automotive markets.
