ABSTRACT:
A portable device includes a location detector, a time detector, and an alarm module to generate alarms based on both time-based and location-based criteria. A current time provided by the time detector is compared to a time-based criterion, and a current geographical location provided by the location detector (e.g., global positioning system or GPS receiver) is compared to a location-based criterion to determine whether or not to generate an alarm.
