A lidded semiconductor device has a first layer applied to the lid, which first layer is chosen of a material which fluoresces upon application of non-visible electromagnetic waves thereto, for example, ultraviolet light. The battery comprises a battery device, wherein a cathode and an anode are wound with a separator in between. An end of the magnetic core includes a curved or bent portion curved toward the circuit substrate. Strap retaining means, each interacting with a strap, are place separately along the first arm shaft. In one embodiment, the folding arms include a coupling device for coupling the arms to a base in a sliding arrangement to enable the arms to slide along the base to a folded position. Pharmaceutical compositions, methods of preparing the compounds, and methods of using the compounds and compositions to treat viral infections are also provided.
