The present invention provides a portable handheld security device. The security device comprises a central processing unit in communication with a memory storage device, a video display screen, at least one camera, a transmitting device, a receiving device, an input device, and a power supply. The security device further comprises a device for generating ultra wide band ground penetrating radar and/or millimeter wave radar for identifying objects of interest in closed containers. In addition, the transmitting device and the receiving device are ideally capable of selecting between available communication network signals, determining which network signal is the best signal at a given time, and automatically switching between the available signals to maintain optimum reception and transmission quality. The input device has a first set of user-interface controls and a second set of user-interface controls, wherein the first and second sets of user-interface controls are selectively operable by users either independently or simultaneously.

Portable handheld security device

A pen-based portable computer, or pen-tablet computer, for use with a vehicular docking station that allows for the exchange or replacement of components thereof without the need for returning the computer to the manufacturer. The computer utilizes a main or primary housing for the major components of the computer, and a separate, independent, auxiliary expansion unit having its own housing for mounting a replaceable radio module that is connected to the main computer via a multi-pin connector, whereby the replacement or exchange of the radio module for a different one is easily and readily achieved, and where auxiliary or expansion devices may be connected to the main computer thereby, and where the auxiliary device itself serves as a handle for holding the main computer. Also provided is a vehicular docking station for the combined main computer and auxiliary unit, which vehicular docking station is provided with a multi-pin connector for receiving thereby a multi-pin connector of the auxiliary unit when the computer is connected to the auxiliary unit.
