PHYSICAL OBJECT DROP AND IMPACT ALARM DEVICE

摘要

The present invention comprises a device which emits an audible sound when it is dropped and impacts upon the ground or other surface. The device is small enough to be easily placed in a user's wallet, on a keychain, or other valuable and will alert the user when these valuables are dropped. The device is comprised of a low power MEMS accelerometer and a low power microcontroller so that the device will stay powered “on” for an extended amount of time, even while using thin, low energy batteries such as coin cells. The audible sound emitting functionality is comprised of a small, low-power piezoelectric buzzer. In normal operating conditions the device will stay “on” and provide maintenance and worry-free operation for many years.
