A protected electrical device having at least one electrical sub-assembly to be protected comprises on at least one of upper and lower surfaces, at least a screening layer against the electromagnetic and radiofrequency fields emitted by the electrical sub-assembly. The lactic acid bacteria and compositions containing the bacteria are capable of providing excellent mucosal immunostimulation effects and are useful for reinforcing the host defense system. The second end includes a proximal end and a distal end, wherein the distal end includes a blunt distal tip shaped and dimensioned for dissecting tissue without unduly causing trauma to the tissue. The data input is automatically stored within a specified memory unit. More particularly, the present application describes internal components configured to fit within a relatively thin outer enclosure, wherein the internal components comprise at least one external interface, such as, for example, a track pad interface.
