Abstract: A method and device for determining whether a product is in condition to be used or consumed, this product being intended to be preserved under temperature conditions and for a period of time which limit its degradation includes an indicator combined with the product, to provide a signal indicating that the product can be used or consumed, and then, after the expiration of a preservation period of time, a signal indicating a change in the condition of possible use or consumption of the product. The period of time depends on the preservation conditions of the product. The indicator provides information enabling the product to be used or consumed for a longer period of time if the product has been preserved under conditions better than recommended conditions or for a shorter period of time if the product has been preserved under conditions worse than recommended conditions.

Abstract: To relieve a user of a first fixed or mobile terminal from consulting messages deposited in a voicemail server, the voicemail server notifies the first terminal of the presence of a deposited message associated with the identifier of a second terminal, immediately after off-hooking and transmission of the identifier. The message is transmitted to the first terminal only if the user wishes to listen to it so as to decide whether or not to hold the call to the second terminal. Otherwise, it proceeds with the setting up of the call to the second terminal.
