Portable device emergency beacon

摘要

In one embodiment, an apparatus can include: (i) a location receiver configured to receive position signals, and to derive location information therefrom; (ii) one or more recognition modules configured to receive usage-related inputs, and to provide a pattern therefrom; and (iii) a processor configured to receive the pattern, and to provide the location information and an emergency indication. For example, particular embodiments can advantageously provide an emergency beacon using voice or other usage-related inputs to a cellular telephone.

主权项

1. An apparatus, comprising:
a location receiver configured to receive position signals and to derive location information of the apparatus therefrom; a content-addressable memory (CAM) configured to store a plurality of predetermined emergency patterns and a plurality of programmed emergency keys, wherein each of the plurality of predetermined emergency patterns and the plurality of programmed emergency keys are stored in one or more entries of the CAM; a speech recognizer configured to receive voice inputs, provide a first lookup key therefrom, and monitor the voice inputs; a pattern recognizer configured to receive a plurality of usage-related inputs and to provide a second lookup key therefrom; and a processor configured to:
receive the first and second lookup keys;determine a first match between the first lookup key and at least one of the plurality of programmed emergency keys such that the first match is only determined if the voice inputs match an authorized user voice data stored as the at least one of the plurality of programmed emergency keys;determine a second match between the second lookup key and at least one of the plurality of predetermined emergency patterns;determine an emergency indication that is associated with the second match; andprovide the location information and the emergency indication for transmission from the apparatus.
