Patent ID: 7881710

Claim:
A portable communication device comprising: a speed detection controller for detecting a first speed of travel at a first time and at least one subsequent speed of travel at at least one subsequent time of said portable communication device independent of any vehicle temporarily transporting said portable communication device; a speed based setting controller for comparing a change in speed from said first speed to said at least one subsequent speed and an amount of time from said first time to said at least one subsequent time with a plurality of emergency thresholds each specifying a sequence of speed changes over a separate specified period of time for controlling at least one call notification feature if said change in speed over said amount of time indicate a particular sequence of speed changes over a particular specified period of time as an emergency when compared with said plurality of emergency thresholds; said speed based setting controller for automatically assigning a separate speed based setting for a particular emergency threshold from among said plurality of emergency thresholds to a separate current setting for each of said at least on call notification feature, responsive to said change in speed over said amount of time exceeding said particular emergency threshold from among said plurality of emergency thresholds; and a device feature controller for controlling an operability of each of said at least one call notification feature according to each said separate current setting for each of said plurality of features.
