    Abstract: Described are RF tracking system and method. The RF system may include a shell for holding a plurality of containers which store a material that interferes with RF communications. The shell includes a bottom container supporting surface and a plurality of leg extensions attached thereto; the shell extends away from the bottom surface. The tracking system also includes at least one RF tag attached to a first one of the leg extensions. The tag has a memory arrangement storing data relating to at least one of an identity of the shell, an identity of the containers held in the shell and a material stored in the containers. Furthermore, the tracking system includes at least one RF scanner communicating with the tag to collect the data and a computing arrangement which includes a database and communicating with the scanner to update the database as a function of the collected data. The tag is situated at a predetermined distance away from the containers held in the shell to overcome an electromagnetic dampening effect of the material.

    Abstract: To reduce the size and weight of an optical scanner, the present invention provides a mirrorless beam scanning unit. In some embodiments, the light emitter itself moves back and forth, and in other embodiments the objective lens reciprocates laterally in front of the light emitter. For example, a flexible support structure, such as one or more strips of mylar, movably mounts the objective lens in front of the light emitter. The objective lens is laterally reciprocated in response to a motive force, for example as might be applied by a combination of a permanent magnet coupled to the objective lens and a fixedly mounted electromagnet driven by an alternating current signal. Reciprocation of the objective lens during emission of light by the light emitter causes the light to scan a surface, such as a surface bearing a bar code label.
