Abstract: A device's arrival at a destination location is automatically detected, and notification of such arrival is automatically generated, without any need for a user to specify the destination location in advance. A perimeter, or geofence, is continually or periodically defined around the device's current location. A timer is automatically set, with some pre-specified duration. If the device exits the geofence before the timer expires, the new location of the device is determined, a new geofence around that location is defined, and the timer is reset. If the timer expires before the device exits the geofence, the device is considered to have arrived at a destination; an “arrives” event is generated. Notification of such an event can be output at the device and/or transmitted to one or more subscribers. Various exceptions, conditions, and preferences can be taken into account so as to avoid false positives.

Abstract: Limits are placed on the number of free and/or discounted communications (such as voice calls and text messages) available to a user, based on the number of communications received by the user. A user is given an allotment of credits, each worth one or more free and/or discounted communications. A credit balance is established and is continually adjusted as follows: it is increased whenever qualifying communications of a given type are received, and is decreased whenever free and/or discounted communications of the given type are initiated by the user. Once the credit balance has been depleted, the user may be blocked from initiating additional free or discounted communications, until the credit balance is increased. In at least one embodiment, different types of credits can be earned and/or used for different types of communications. In at least one embodiment, exchanges between the different types of credits may be permitted.

Abstract: A fully integrated email system for a desktop computer with an associated palmtop computer is disclosed. The portable computer has an email client for viewing incoming email messages and composing outgoing email messages. The personal computer has an email synchronization conduit that synchronizes email on the portable computer email client with email for the desktop computer system. The email synchronization conduit ensures that the email state on the portable computer system matches the email state on the desktop personal computer system exactly. Thus, if an email message is deleted on the portable computer system then that email message will be deleted from the desktop personal computer system. Similarly, if an email message is deleted on the desktop personal computer system then that email message will be deleted from the portable computer system.

Abstract: A device for providing wireless Internet access has been described. The device includes an antenna. The antenna is for receiving wireless queries and transmitting wireless responses. The device includes a program. The program is for converting the wireless queries into Internet compatible protocols. The program is for receiving the Internet protocol formatted responses. These responses are then converted in to the wireless responses.
