A variation measurement device for a physical activity includes a display element that displays a variation amount of a weight data from a benchmark of the weight data, which varies depending on the physical activity of the measurement subject.

A pressure-sensitive device and a computing device are configured to register various steps of a meal lifecycle, including one or more of food purchasing, meal preparation, the serving and consumption of a meal, use of leftovers, management of food inventory, the transferring of a food item from one container to another, the transferring of a food item into a container, the transferring of a portion of a food item into a container. A food item may be automatically identified based on a weight and footprint of the food item. In some instances, a database associates a food item with multiple footprints such that a food item may be identified regardless of its orientation on the pressure-sensitive device.

A stock management method and system utilizes a mat that includes a plurality of sensors corresponding to a plurality of sensing areas, each of sensors is configured to sense an item placed on a certain sensing area. Partitions define a plurality of lanes on the mat. A controller receives sensing results of the plurality of the sensors and calculates a stock level of remained items on the mat based on the sensing results. One of the sensing areas is located in both of two lanes of the plurality of lanes.

A printing apparatus communicates with a weight measuring apparatus and a mobile terminal. The weight measuring apparatus transmits measuring data of weight of a measurement object, and the mobile terminal transmits a data acquisition command requesting for transmission of the measuring data. The printing apparatus includes a head to execute printing on a print medium, and a controller. The controller is configured to: receive the data acquisition command from the mobile terminal; change a state of the printer from an instruction waiting state to a data reception waiting state; receive a second measuring data transmitted from the weight measuring apparatus; transmit the second measuring data to the mobile terminal; receive a print command corresponding to the second measuring data from the mobile terminal; and control the head based on the received print command to perform the printing, on the print medium, corresponding to the second measuring data.

A weighing machine includes a weighing unit that measures the weight of a product placed on a weighing table, a calculation unit that calculates the price of the product based on the weight of the product measured by the weighing unit, and a control unit that sets the price calculated by the calculation unit when the product is removed from the weighing table.
