Embodiments describe a receiving element that includes a ferromagnetic structure axially symmetrical around a central axis disposed along a length of the ferromagnetic structure. The ferromagnetic structure includes a groove region defining two end regions on opposing sides of the groove region, where the groove region has a smaller length than the two end regions. The receiving element also includes an inductor coil wound about the groove region of the ferromagnetic structure and in between the two end regions.

An inductive power system including an inductive power transmitter coupled to a non-conductive medium, and a power cord that electrically couples the transmitter to an AC power source. The inductive power transmitter is configured to emit an electromagnetic field based on the received AC power. There is an inductive power receiver coupled to the non-conductive medium and separated from the transmitter, wherein the receiver is configured to receive the electromagnetic field after it has passed through the non-conductive medium and in response develop power. A power cord electrically couples the developed power to a power sink.

A periodic arrangement of magnets are used to form structures that channel the potential energy that a magnet possesses into kinetic energy in a controlled fashion to perform some useful work or function. One function is to create a magnetic chute that converts the potential energy of a magnetic projectile into kinetic energy that is used to channel the projectile to follow a path achieving high velocities along a path. The path is formed by assembling magnets periodically along the path in a certain fashion to create a magnetic chute that allows the magnetic projectile to slide easily along the path since the projectile is confined by the shape of the magnetic chute.

A package structure comprises a backing plate supporting a target object, at least one pad disposed on the backing plate and fixing the target object, a frame disposed on a lower side of the backing plate, bonded to the backing plate, and supporting the backing plate to fix the pad onto the backing plate, and a side enclosing plate disposed around the backing plate and connected to the pad to fix the pad. The package structure further comprises a magnetic component disposed on the backing plate and attracting a magnetic coating on the target object.
