Abstract: A method including receiving, at a first computing system from a second computing system, a first key and encrypted online interaction data, receiving, at the first computing system from a third computing system, a second key and encrypted offline action data encoding data indicating one or more offline actions, receiving, at the first computing system from the third computing system, executable code comprising a third key, and executing, by the first computing system, the executable code. The executable code causing the first computing system to decrypt the encrypted online interaction data and the encrypted offline action data using the first key, the second key, and the third key, correlate one or more of the offline actions in the offline action data to one or more online interactions in the online interaction data, and generate aggregate data indicating a number of offline actions correlated to the online interactions.

Abstract: A method disclosed herein may include receiving, at a first computing system, encrypted identifiers and encrypted values, performing, by the first computing system, a concealing operation on the encrypted identifiers to produce concealed encrypted identifiers, wherein the concealing operation conceals the encrypted identifiers from the first computing system and a second computing system but enables matching between the concealed encrypted identifiers, decrypting, by the second computing system, the concealed encrypted identifiers to produce concealed identifiers, and performing, by the second computing system, an aggregation operation using the concealed identifiers and the encrypted values to produce an encrypted aggregate value without accessing personally identifiable information associated with the encrypted values.

Abstract: A device that mounts onto the front of a kayak to assist in righting the kayak after it rolls over. It consists of a small mast that is attached to a hinged base. An inflatable bag is attached to the top of the mast along with equipment to inflate the bag. A lanyard is attached to the inflation equipment and to the top of the mast. In a rollover, the user pulls the lanyard, which causes the bag to inflate and the mast to rotate 90 degrees. This places the mast perpendicular to the kayak with the inflated bag at the far end of the mast. The inflated bag acts like an outrigger that causes the kayak to roll back upright automatically. In this way, the kayak is turned upright with minimal problems and difficulties for the user.
