Abstract: Methods for generating one or more atmospheric pressure plasma jets that can be used to deposit various types of conductive traces, coatings, and micro/nano-sized particles/structures on two or three dimensional body surfaces. The method includes generating atmospheric pressure plasma, nebulizing a precursor to generate an aerosol; receiving the aerosol from the nebulizer in a chamber; mixing the atmospheric pressure plasma with the aerosol from the chamber at a nozzle; and printing the plasma-exposed aerosol onto the surface of a substrate.

Abstract: A system and a method are disclosed for tracking user activity with products in an environment. In an embodiment, a processor detects that a user has entered an environment, and responsively uniquely identifies the user. The processor determines that the user interacts with a product of a plurality of products within the environment, and responsively updates a profile of the user with indicia of the product. The processor determines whether the user is attempting to exit the environment, and, in response to determining that the user is attempting to exit the environment, prompts the user to confirm that the user intends to remove the product from the environment based on the updated profile. The processor receives input from the user confirming that the user intends to remove the product from the environment, and responsively further updates the profile based on the input.

Abstract: A system and a method are disclosed for disambiguating between anonymous users associated with multiple transactions. In an embodiment, a system receives information about a transaction and generates a profile of the anonymous user associated with the transaction. In response to another transaction, the system compares the transactions to determine whether the same anonymous user is associated with both transactions. Upon determining that the same anonymous user is associated both transactions, the system adds information about the new transaction to the profile of the anonymous user.

Abstract: A system includes an input to receive at least one electrophysiological signal representing cardiac electrical activity measured from a body surface of a patient. The system also includes a signal processor to analyze the at least one electrophysiological signal and compute a score having a value to indicate a likelihood of arrhythmogenic activity, the score being computed as a function of at least two of cycle length, amplitude and polarity of the at least one signal.
