A sensing system comprising a sensor for generating an analog electrical signal indicative of a sensed physical property and an AD converter for converting the analog electrical signal into a digital electrical signal. The waveform signal from the sensor is converted into digital form. The lateral opening can be closed by a cover, which is additionally shaped on its inside in such a way as to promote flow distribution or heat dissipation. The molding encapsulates the die, the bonding wire, and the top surfaces of the first and second plated areas, such that the bottom surfaces of the first and second plated areas are exposed exterior to the package. Thus, in one embodiment, the universe of people to whom the license server can issue licenses can be expanded by adding new identity servers to the list of trusted identity servers.
