7. A portable processing unit capable of engaging in data updates with a base processing unit, comprising:
-
a receiver operable to receive an update request signal from the base processing unit over a wireless communication channel, the update request signal indicating that a data update between the base processing unit and the portable processing unit is advisable; and
an alarm circuit operable to produce an alarm, that is perceivable by a user of the portable processing unit, in response to the update request signal indicating that a data update routine between the base processing unit and the portable processing unit should be initiated by the user, wherein;
the one or more portable processing units include a universe of portable processing units and the update request signal includes a code from among a plurality of codes unique to one of the portable processing units of the universe; and
the receiver is further operable to determine whether the code of the update request signal corresponds with the portable processing unit such that the alarm circuit issues the alarm only when the correspondence exists. - View Dependent Claims (8, 9, 10, 11)
the one or more portable processing units include a universe of portable processing units and the update request signal includes a code from among a plurality of codes unique to a subset of the portable processing units of the universe;
the receiver is further operable to determine whether the code of the update request signal corresponds with the portable processing unit such that the alarm circuit issues the alarm only when the correspondence exists.
