An information processing apparatus is configured to repeatedly perform, within a predetermined period, a meal managing process of generating meal management data including data indicating an extra calorie within a predetermined period, and an exercise managing process of generating exercise management data including data indicating an amount of deficient exercise within the predetermined period. The extra calorie is calculated based on a total intake calorie of a user for a period from a start point of time of the predetermined period to a point of time when the extra calorie is calculated and total calorie consumption of the user for the period, and the amount of deficient exercise is calculated as an amount of exercise required to consume the extra calorie.

An adhesively coupled power-meter measures one or more of force, torque, power, and velocity of a mechanical arm. The power meter includes a plate with a first surface prepared for adhesively coupling to the mechanical arm. At least one strain gauge is physically coupled with a second surface, opposite the first, of the plate and with an orientation corresponding to an orientation of the adhesively coupled power meter such that mechanical forces are transferred from mechanical arm to the at least one strain gauge when the plate is adhesively coupled to the mechanical arm. The power meter also includes electronics for receiving a signal from the at least one strain gauge and for determining one or more of force, torque, power and velocity from the signal, and a wireless transmitter for transmitting one or more of force, torque, power and velocity to a receiving device.

Methods and systems are disclosed to detect whether a treadmill user is in the danger of falling off the treadmill and to accordingly warn the user via, e.g., audio and haptic feedback. In the event the runner falls off the treadmill and becomes hurt or unresponsive, the system can automatically notify emergency contacts, e.g., via phone calls or text messages.
