System and method for identifying, measuring and analyzing food nutritional values and consumer eating behaviors is disclosed. A food container, having weight sensors and food identification sensors, identifies weight, type, and preparation status of the food item being consumed by the user from the food container. Based on the identified information, the nutritional value of the food item is determined and observed. The food container in communication with the system components may provide the user a recommended meal plan to improve the user's health condition. In addition, the food container issues an alert to the user when the user puts too much, too less, or the right amount of food items in the food container or eats the food items too fast.

A landing pad receptacle receives and stores a package delivered by an unmanned vehicle, comprising: a housing; a storage compartment in the housing; and a validation device that detects a presence of a package delivered by a unmanned vehicle in the storage compartment and authenticates a package for return by a unmanned vehicle.

A sensor device is utilized to perform a first measurement of a first content fill level of a first container at a first instance. The same sensor device is utilized to perform a second measurement of a second content fill level of a second container at a second instance. Based at least in part on an analysis of both the first measurement and the second measurement, it is automatically identified that the sensor device has been moved from the first container to the second container. Based at least in part on the identification, an inventory record tracking a number of remaining full containers is automatically updated.

An eating utensil (100) is provided which comprises a handle (120) and a food area (110). The eating utensil (100) comprises an accelerometer sensor a gyroscope sensor (150). With the accelerometer sensor the gyroscope sensor (150), the movement of the eating utensil (100) as well as its orientation is detected. The orientation as well as a movement of the eating utensil (100) can be compared with a predetermined ideal traversal path and orientation of an eating utensil (100) and the user may receive corresponding feedback if the detected path or orientation of the eating utensil (100) differs from the ideal utensil traversal path or orientation.

An illuminated coaster comprising a plurality of light emitters, and a control unit associated with the illuminated coaster are provided. The control unit comprises a memory configured to store computer-executable instructions. The control unit comprises a processor in communication with the memory, the processor being configured to execute the computer-executable instructions, which when executed, cause the processor to detect presence of a container on the coaster, estimate a volume of liquid within the container present on the coaster, and activate a plurality of light emitters to emit one of a light of first color, a light of second color, or a light of third color based on the estimate volume of liquid.
