Methods, apparatuses, and systems for wireless power transfer (WPT) in ball-and-socket type structures are provided. A ball and ball-socket structure can include conductive windings and conductive plates having a variety of shapes to optimize WPT over different angles as the ball moves or rotates within the ball-socket. One or both of capacitive coupling and inductive coupling can be incorporated.

A transformer device includes a transformer circuit having a shape arranged to be connected to another transformer device, and a connector provided on one side of the transformer circuit such that the transformer circuit is connected to a cable connected with another transformer device where the transformer circuit is configured to be connected to a transformer circuit of another transformer device through the cable to increase a voltage or current provided to a load.

An individualized vehicular charging mat includes a body defining two tire channels terminating at respective channel ends, and a wireless charging element arranged within or on top of the body. The two tire channels include respective entrances at a side edge of the body, and are separated by a track width for a particular vehicle make, model and model year(s). The wireless charging element is arranged at a location where the wireless charging element is configured to optimally charge a vehicle of the particular vehicle make, model and model year(s) when tires of the vehicle come to rest at the channel ends.

A mobile object apparatus includes an electric power reception unit that receives electric power transmitted in a non-contact manner from, out of a plurality of power feed apparatuses that are allocated to a plurality of small areas within a predetermined area and are capable of transmitting electric power in a non-contact manner, the power feed apparatus allocated to the small area adjacent to the mobile object apparatus, a drive unit that executes a movement operation on the predetermined area, and an electric power storage unit that stores an electric power amount requisite for the movement operation to the small areas located next to the adjacent small area.

A current transformer includes a first housing including a first handle portion and a first distal portion, a second housing including a second handle portion and a second distal portion, a first core mounted in the first distal portion, a second core mounted in the second distal portion, and a lock attached to the second handle portion at a pivot point, wherein the first housing is rotationally coupled to the second housing about a fulcrum point and the lock is rotatable about the pivot point into a closed position wherein the lock engages the first handle portion and prevents the first handle portion and the second handle portion from rotating towards each other.
