Abstract: A system and method pairs devices in a gym environment. The system includes: a server computer; a plurality of data collector devices, each of the plurality of data collector devices being associated with a gym device or an exercise spot of a gym, wherein each data collector device includes a wireless communication unit, and a memory configured to store training data of a user; one or more time-of-flight positioning units configured to be disposed at fixed locations in the gym and conduct time-of-flight positioning; one or more mobile tag devices, each mobile tag device comprising a time-of-flight positioning unit configured to conduct the time-of-flight positioning together with the time-of-flight positioning units at the fixed locations; and one or more wearable devices, wherein each wearable device is associated with one of the one or more mobile tag devices.

Abstract: A bicycle computer for monitoring performance of a user of a bicycle includes a processing circuitry; a user interface; an attaching unit for arranging the bicycle computer in an attached position; and at least one integrated proximity sensor arranged and dimensioned to measure, in the attached position, proximity data being indicative of a distance to a body part. The processing circuitry is configured to obtain the proximity data from the at least one integrated proximity sensor and to process the proximity data into one or more cycling metric. The user interface is configured to output the one or more cycling metric.

Abstract: A system for monitoring performance of a user includes at least one processor, and at least one memory including a computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the system to perform operations including obtaining force data measured by at least one force sensor coupled with one or more poles and velocity data measured by at least one sensor for measuring velocity of the user, determining poling power based on the force data and the velocity data, and outputting a poling power indicator based on the determined poling power.
