Abstract
This disclosure relates to a let calling system and method, which is configured to determine that a let has occurred based on ball flight characteristics, as opposed to, for example, monitoring for changes in the net. In an example method, following a serve of a tennis ball, the method indicates that contact between the tennis ball and a tennis net has occurred when a flight characteristic of the tennis ball changes by a predetermined threshold amount in an area adjacent the tennis net.

A method, comprising:
- following a serve of a tennis ball, indicating that contact between the tennis ball and a tennis net has occurred when a flight characteristic of the tennis ball changes by a predetermined threshold amount in an area adjacent the tennis net.
A system, comprising:
- a sensor configured to generate signals indicative of a flight characteristic of a tennis ball;
- and
- a controller configured to interpret signals from the sensor and, based on the signals from the sensor, to indicate that contact between a tennis ball and a tennis net has occurred when the flight characteristic of the tennis ball changes by a predetermined threshold amount in an area adjacent the tennis net.
