Patent ID: 8909190

Claim:
A portable compatibility detection device comprising a microcontroller, a radio frequency communication means operably coupled to the microcontroller, a first nonvolatile memory in which user data is stored, said first memory being operably coupled to the microcontroller, a second nonvolatile memory in which a data comparison instruction set is stored, said second memory being operably coupled to the microcontroller and said data comparison instruction set being executable by the microcontroller, a visual display operably coupled to the microcontroller, said user data including a dataset describing the user and a first dataset describing a personal preference of a user, said radio frequency communication means being configured to receive radio frequency signals directly from and send radio frequency signals directly to a compatible remote portable device within communication range, said compatible remote portable device being controlled by a second user, said microcontroller executing the data comparison instruction set to determine an extent to which the dataset describing the personal preference of the user is met by second user based upon a second dataset extracted from the radio frequency signals received from the compatible remote portable device within communication range via the radio frequency communication means, said second data set including personal preference data of the second user, and said microcontroller being configured to cause the visual display to present a visible indicator of the extent to which the dataset describing the personal preference of the user is met by second user.
