Abstract: Systems and methods are disclosed for selecting offers based on segmentation of users targeted for the offers. To personalize the offer selection for a user while avoiding the processing burden of selecting offers tailored at an individual user level, an offer selection optimizer system divides targeted users into persona segments based on the behavior of the targeted users with enterprises or offers. The system selects an offer based on initial weights applied to respective parameters of candidate offers, where the candidate offers may be scored using a weighting function. The weights may vary depending on the persona segment for which the offer is scored. The system may modify the initial weights to generate exploration weights, which are used to select exploration offers. Users' activities with the generated offers are tracked to update the initial weights. The system can generate subsequent offers using the updated weights.

Abstract: Systems and methods for detecting and measuring cardiac contractile function of a heart using an acceleration sensor unit inserted within the heart, such as within a vein of the cardiac wall are disclosed. The systems and methods involve detecting the occurrence of electrical events within the patient's heart by inserting and positioning an implantable lead having an electrode near a cardiac wall as well as detecting mechanical events within the patient's heart by then inserting and positioning a cardiac motion sensor unit through the inner lumen of the implantable lead. Furthermore, the systems and methods do not require dedicated leads and may be used with preexisting implantable leads.
