  • Method and apparatus for reducing the likelihood of losing a portable electronic device
    Patent number: 6836212
    Abstract: A loss prevention system (e.g., 200) employs a method and apparatus for reducing the likelihood of losing a portable electronic device (100, 201) that has been inadvertently removed from its retaining device (e.g., 203, 300, 400). The loss prevention system includes the electronic device and its retaining device. The electronic device includes a proximity detector (103) that operates to detect the absence or removal of the device from the retaining device. The electronic device further includes a lost device detection circuit (102) that determines whether the removal was intentional and, if unintentional, alerts the user of the removal. By so alerting the user, the loss prevention system provides rapid feedback to the user after the user's electronic device has inadvertently fallen out of its retaining device, thereby enabling the user to quickly retrieve the device before it gets damaged or taken by someone else.
