Abstract: A system for managing a list of products in an inventory includes a plurality of addressable LEDs, each for positioning adjacent a product storing position that includes an identification code; at least one code reader; and at least one controller coupled to both the plurality of addressable LEDs and the at least one code reader for i) receiving from the code reader a command indicative of the list of products; and ii) as a result of the command, controlling the addressable LEDs so as to energize LEDs therefrom corresponding to the list of products. A method for managing the list of products further includes verifying an identity of each product from the list by reading and comparing the identification code thereof to the identification code associated to the corresponding addressable LED.

Abstract: A method for cleaning a septic tank provided with at least two successive fermentation and decantation compartments connected to each other by a lateral opening. According to this method, the light and/or heavy sludges contained in each compartment are pumped and discharged in a waste tank whereas the bacteriological liquid medium of both compartments is pumped out and stored in a storage tank. The liquid medium kept in the storage tank is reintroduced into the septic tank after the same has been cleaned, to reactivate said tank thereby making it immediately operative. A tanker especially designed for carrying out this method is also disclosed.
