Techniques are provided for resolving ambiguity in natural language speech. The packaging apparatus includes a plurality of independently rotatable rotary slats. In an exemplary embodiment, the handset takes advantage of a priori computed andor measured electromagnetic interference profiles to reduce or minimize interference among components in the device. The base assembly includes a top wall, a bottom wall, and a sidewall that together form or define an inner chamber. In some implementations, the device can transmit the collected data as an email message. The component also includes contacts on a circuit side of the substrate, conductive vias in electrical contact with the contacts, and conductors on a backside of the substrate.
