Abstract: A device (12) for interfacing an external peripheral unit (18) to a store controller (16) and store terminal (14) of a point of sale (POS) system has been provided. The interface device includes an MPU (50) for passively monitoring the data coming from the store terminal without causing any interruption to the POS system. When a specific key sequence indicative of a request for use of the peripheral unit has been detected, the device interrupts the flow of data between the store controller and store terminal and enables the MPU to now send data to the store controller and store terminal. Additionally, the device provides a plurality of data paths for allowing the MPU to read data from the store terminal, for storing and reading data from the store controller, and for transferring data between the MPU and the peripheral unit.

Abstract: The disclosure herein describes a plant assembly that includes a pot and a saucer adapted to be nested together in similarly constructed assemblies; the pot consists of an inverted frusto-conical body with an elongated hollow conically-shaped central part upwardly extending from the bottom wall thereof; the saucer consists of a cylindrical body that includes also a frusto-conical central part that extends upwardly from the bottom wall. Both central parts have enlarged lower areas defining supports allowing similarly constructed pot and saucer assemblies to be nested one within the other.
