Abstract: Consumption of safe beverages improves health, physical performance, and prevents disease. A system includes a device that monitors a beverage within a vessel to determine if the beverage is safe to drink. The device may include a pH sensor to determine a pH value of the beverage. This pH value is compared to a pH range that is deemed safe. A comparison between the pH value and the pH range may be made, and the results presented to a user. The system may include a mixing device to automatically mix the beverage, or the system may prompt a user to manually mix the beverage. Data from other sensors may also be used to assess the beverage. The device may be implemented in various form factors such as a cup, lid, straw, stirrer, and so forth. The device may communicate with other devices, such as a phone, tablet, or server.

Abstract: A system may use a sensor device affixed to the user or an article of clothing of the user to provide information on performance of an activity. For example, a sensor device may be affixed to a portion of the laces on footwear of the user. Acquired data from the sensor device may be processed to provide analysis information to the user about the performance.
