Abstract: A device for the detection of a food allergen includes a sensor having a printed circuit board and a chip comprising a molecularly imprinted polymer (MIP) and a non-imprinted polymer (NIP); a reservoir comprising a liquid; and a chamber for mixing the liquid with a food.

Abstract: A device for detecting an ingredient in a food sample includes a cap having a first piercer member and a collar that receives the food sample and couples to the cap. The collar includes a first frangible barrier and a grinding assembly, which includes a second piercer member, disposed between the first frangible barrier and a second frangible barrier spaced therefrom. The collar further includes a sensor disposed below the second frangible barrier. The first and second frangible barriers form a first chamber containing a buffer solution, and the second frangible barrier and the sensor form a second chamber. Responsive to coupling the cap and collar, the first piercer member pierces the first frangible barrier and the second piercer member pierces the second frangible barrier. After the first and second frangible barriers are pierced, the food sample passes through the first and second chambers to be received by the sensor.

Abstract: A device worn or carried by a user includes a subsystem including a processor, memory, wireless communication interface configured for communication over a maximum range between 1 and 10 meters, indicator(s), and electrical power source. The memory stores first profile data characterizing trait(s) of the user and second profile data characterizing interest(s) of the user. The first profile data is communicated by the wireless communication interface to at least one other device located within its maximum range. The processor receives and processes profile data wirelessly communicated from one other device located within the limited range of the wireless interface. The received profile data characterizes a person or group or entity or product or service associated with the other device. The processor processes the received profile data by matching the received profile data and the locally stored second profile data, and controls the at least one indicator based upon such processing.
