Abstract: One variation of a method for fulfilling custom food orders includes: in response to request for a custom food order from a patron through an ordering portal executing on a computing device, retrieving a location of the computing device; identifying a set of food assembly apparatuses within a threshold distance of the location of the computing device; aggregating a list of ingredients currently loaded into the set of food assembly apparatuses; in response to selection of a particular ingredient in the list of ingredients for the custom food order, removing ingredients, from the list of ingredients, unique to a food assembly apparatus not currently loaded with the particular ingredient; selecting a particular food assembly apparatus, from the set, currently loaded with a set of ingredients specified in the custom food order; and inserting the custom food order into a food order queue assigned to the particular food assembly apparatus.

Abstract: A system and method for detecting leaks in a storage tank that includes a stored tank liquid and an immiscible test liquid, and there is an interface formed between the tank liquid and the test liquid. The system includes a transducer and electronic device. The transducer further includes a measuring cell and a standard cell. The level of the interface within the standard cell does not change when the level of the interface changes. The level of the interface within the measuring cell changes according to the level of test liquid in the storage tank. The signal generated by the cells are processed by the electronic device to indicate whether there is leakage in the storage tank.
