Abstract: The operation of a conventional cellular telecommunications transceiver that forms part of a vehicle's telematics system can be selectively changed in order to provide telephone calls by providing the transceiver with a second and different SIM card. Providing a second SIM card, however, will disable telematics service that can include stolen vehicle tracking. A personal identification number or PIN is thus required in order for the information that is stored in an external, user-provided SIM card to be used by a telematics system transceiver rather than the information stored in a built-in SIM card that is provided by a telematics system operator/provider.

The system identifies when a serving utensil is removed from a serving utensil holster or a serving utensil rest and initiates the clocking circuit. The system monitors the status of the serving utensil and the passing time. When the passing time exceeds a predetermined allowable “in-use” time period, the system initiates an alert. The alert can be a visual alert, an audible alert, or any other alert. The alert can escalate if the serving utensil is not returned to the holster/rest in a timely manner. The system can associate a specific serving utensil with the respective monitoring system to avoid cross contamination. The system can additionally include a sterilization component. The system can be integrated into a utensil status and data acquisition system.
