US Patent 7355928 Mobile wakeup device

A mobile wake-up device responds to a snooze-button in an alarm clock. The mobile wakeup device includes a mechanism for making the device mobile, a controller for directing the movement of the device and responding to input, and an alarm off input. When the alarm clock's alarm goes off and an individual activates the snooze button, the mobile wake-up device moves forward, drops from a table to the floor, and moves to a remote location. While moving, the device may use sensors to avoid objects in its path. After the mobile wake-up device has reached the remote location, the alarm signals again. To turn off the alarm, the individual must get out of bed and locate the mobile wake-up device.
