Abstract: Provided is an energy harvesting device, comprising a first shell having a longitudinal axis, wherein the first shell defines a cavity, and a second shell, wherein the second shell is mechanically connected to the first shell via a flexible cord, wherein the cavity comprises therein a bearing, an electrical generator, and a battery, wherein the bearing is mechanically coupled to a rotor of the electrical generator at a first end and an end of the flexible cord at a second end, such that rotation of the flexible cord about the longitudinal axis rotates at least a portion of the bearing to generate electrical power, and wherein the rotor is in electrical communication with the battery, such that the battery stores at least a portion of the electrical power generated by the electrical generator.

Abstract: A system and method for incentivizing charitable giving based on physical activity includes a computer and a sports ball associated with a first participant identifier. The sports ball includes a sensor that detects and logs activity data. The activity data is received by the computer, and in further transmitted to a server. The server stores the received activity data in a participant record associated with the first participant identifier and assigns a plurality of credits to the participant record associated with the first participant identifier based on the activity data stored in the participant record. Software executing on the server generates a report based on the credits assigned to the participant record associated with the first participant identifier and transmits the report to a participant computer associated with the first participant identifier.

Abstract: A ball includes a shell defining a spheroid. The shell includes an opening and a panel to close the opening. The panel has a sleeve that extends radially inward. A generation module is disposed in a cavity defined by the shell. The generation module includes a housing. A pendulum, an electric generator, and a battery are disposed in the housing. The pendulum is mechanically coupled to a rotor of the electric generator at a first axis of rotation of the pendulum and the electric generator is electrically coupled to the battery. An acceleration of the ball causes the pendulum to rotate about the first axis of rotation. The rotation of the pendulum rotates the rotor of the electric generator. The rotation of the rotor of the electric generator generates electricity, and at least a portion of the generated electricity is stored by the battery.

Abstract: A jump rope includes a first handle and a second handle. A rope connects the first handle and the second handle. The first handle defines a cavity. A generation module is disposed in the cavity and is fixed relative to the handle. The generation module includes a bearing, an electric generator, and a battery. A rotor of the electric generator is mechanically coupled to the bearing and an end of the rope is also coupled to the bearing. The electric generator is electrically coupled to the battery. Rotation of the rope relative to the handle causes at least a portion of the bearing to rotate relative to the handle. The rotation of the bearing rotates the generator which generates electric energy, at least a portion of which is stored in the battery.
