Abstract
An apparatus including a removable modular insert disposed within a housing of a host device, the housing including one or more magnets, and one or more conductive contacts disposed on the removable modular insert to magnetically couple to the one or more magnets and secure the modular insert within the housing of the host device, and electrically couple the modular insert to the host device. A conductive coil can be coupled to the modular insert to electromagnetically receive power from a base device having a surface, where the host device moves and operates along the surface of the base device. The apparatus can include a communication device and a processor to control the communication device for communication between the modular insert and the host device, and control operation of the conductive coil. The communication device further controls the electromagnetic coupling between the modular insert and the base device.
