An electrical connector apparatus includes an electrically insulating base, and a conductor extending through the base. This sensor array may also contain ground penetrating radar and EMI coils. These regions are synthesized after error diffusion processing is applied to each region. The concave surface and the inner surface of the substantially cylindrical section conjointly define a cavity. A method in accordance with an embodiment of the present invention includes: retrieving information from a user associated application; dynamically generating a message button based on the retrieved information and a user policy; and rendering the dynamically generated message button on the IM interface.
