Mobile Door Knocker Apparatus and Method of Operation

Abstract

A mobile door knocker causes a portal to open for an authenticated user. A physical access control system actuates upon receiving a wireless request triggered by a pattern of indicia in the vicinity of a portal. A hand-held communication device transmits a portal access control signal when it recognizes a pattern of bursts in signal amplitude. A mobile device has a sensor package, communication circuits, and a processor. Upon determining proximity to a controlled portal, the sensor package enables a pattern recognition circuit. Upon receiving a success indicia from the pattern recognition circuit, the communication circuits authenticate with the controlled portal. A sensor package may be enabled by accelerations from tapping the device against a door, wall, or table. A pattern may be related to a number, or a sequence, or combination of slows, pauses, and quicks, or a curvilinear acceleration.
