Abstract: Systems and apparatus for monitoring physiological electrical activity of an individual include a first electrode unit for receiving a first signal indicative of electrical activity at a first location on a body of the individual and a second electrode unit for receiving a second signal indicative of electrical activity at a second location on the body of the individual. Each of the first and second electrode units may be operated in a field-sensing mode wherein the electrode unit is placed on or in proximity to the individual's skin. The first and second electrode units comprise a capacitive sensor element, and the capacitive sensor element of each of the electrode units comprising an electrodynamic sensor which is sensitive to electromagnetic waves; and an antenna comprising an electrically conductive radiating element for receiving electromagnetic waves.

Abstract: Systems and apparatus for monitoring heart muscle activity of an individual include a first electrode unit, for receiving a first signal indicative of electrical, activity at a first location on a body of the individual and a second electrode unit for receiving a second, signal indicative of electrical activity at a second location on the body of the individual. Each of the first and second electrode units is configurable to operate in a field-sensing mode wherein the electrode unit is placed on or it! proximity to the individual's skin, and a current-sensing mode wherein the electrode unit is coupled to a resistive sensor sensing element placed directly on the individual's skin. The field-sensing mode can be either non-contact field-sensing mode.

Abstract: A system and method for creating a watchlist and selectively providing this information to a user are provided. The system permits a user to access a website and identify items of the website that are of interest. The system stores the identified items in a watchlist for later retrieval, review, transmission or action by the user. The system may periodically inform the user of any changes to the items of interest. Items may alternatively be added from multiple websites, multiple emails or automatically by the system.

Abstract: A system and method for creating a watchlist of products relating to any type of item/service/event for which any type of purchase may be made by a user. The system permits a user to access a website and identify items of the website that are of interest and other users (or friends) and associate one or more users with one or more items in the watchlist. The system stores the identified items and friends in a watchlist for later retrieval, review, transmission or action by the user. The system may periodically inform the user of any changes to the items of interest or any changes in purchases made by the users friends to items in the watchlist. Items may alternatively be added from multiple websites, multiple emails or automatically by the system.
