摘要： An acoustic wave device system with its piezoelectric layer originating from a single crystal piezoelectric wafer/substrate is invented along with sets of detailed process steps to fabricate such a device using wafer-to-wafer and/or die-to-wafer bonding technologies. The proposed device system is particularly good to make bulk acoustic wave (BAW) devices. Methods allowing the single crystal piezoelectric wafer/substrate to be re-used are also given. The proposed methods include detailed process steps to allow heterogeneous integration of electrical chips into the system in a very cost efficient manner. The invention provides a practical and low-cost approach to fabricate the radio frequency (RF) front end chip incorporating RF filters and electronic components integrated into a small footprint which is particularly useful for mobile device and RF stations.

摘要： Fall detection method and systems with its unique designed sensors are disclosed. The capacitive sensing based systems use the abrupt changes of the capacitance value to detect whether a real fall event happens, while the reed sensor/or reed switch based systems work in power saving passive mode to detect the real fall event by analyzing the binary “on/off” signal available from the reed sensor/or reed switch. Both rely on the orientation change of the host body respects to local gravity direction during the falling process. The system can present either as a standalone system or a built-in component with supporting software installed on other devices.
