An emergency readiness verification system includes a housing, a secure weight-sensing mechanism, a vertically-actuated switch assembly, a vertically-adjustable calibration mechanism, and an alert device in communication with the vertically-actuated switch assembly. The vertically-adjustable calibration mechanism fixes a vertical position of the vertically-actuated switch assembly such that an engagement tab of the attachment extension engages an actuator of the vertically-actuated switch assembly when a weight of the fire extinguisher supported by an extinguisher attachment falls is within an alert threshold, and disengages the actuator when the weight of the fire extinguisher falls below the alert threshold or when the fire extinguisher is not supported by the extinguisher attachment.

An active foodware system senses food characteristics, such as weight, calories, and other nutrition. Dining dishes are removably mated with dish holders supported by a mechanical structure having visual stimulating, sensing, and wireless communication components. A visual stimulating component emits light from a dining dish. The mechanical structure protects the components and circuitry from liquid. The system may include a camera. Other components may provide data processing, auditory and haptic stimuli, wireless power, temperature sensing, and heating of food. Data related to the food is displayed on a visual stimulating component of a computer or mobile communication device, such as a mobile phone or tablet computer. The data may also be sent to the internet. Computer software displays nutrition information on the visual stimulating component, which may be displayed before, during, and/or after dining. Computer software may also provide visual and auditory encouragement for children to eat.

Systems and methods of detecting, identifying, and classifying objects positioned on a shelf are provided. In one exemplary embodiment, a sensor pad comprises a plurality of electrical contacts disposed in the pad as a matrix of rows and columns of electrical contacts. Further, each contact corresponds to a different surface area of the pad and has a first electrical conductor positioned on a first layer and a second electrical conductor positioned opposite to the first conductor on a second layer. Also, at least one of the first and second conductors is operable to vary in resistance or capacitance based on an amount of pressure applied to that conductor. In addition, each contact is configured to enable an electrical connection between the first and second conductors with a resistance or capacitance that varies based on an amount of pressure applied to a corresponding area of the pad when an object is positioned on that pad.
