Methods and system for cycle recognition in repeated activities by identifying stable and repeatable features
A system and method for monitoring performance of a repeated activity is described. The system comprises a motion sensing system and a processing system. The motion sensing system includes sensors configured to measure or track motions corresponding to a repeated activity. The processing system is configured to process motion data received from the motion sensing system to recognize and measure cycle durations in the repeated activity. In contrast to the conventional systems and methods, which may work for repeated activities having a high level of standardization, the system advantageously enables recognition and monitoring of cycle durations for a repeated activity, even when significant abnormal motions are present in each cycle. Thus, the system can be utilized in a significantly broader set of applications, compared conventional systems and methods.

Telematics devices and methods for vehicle ignition detection
Exemplary embodiments are provided of telematics devices and exemplary corresponding methods. In an exemplary embodiment, a telematics device generally includes a controller, a wireless communication module to transmit ignition information to a remote station, a power input terminal to sense a voltage of the battery, and an ignition input terminal to couple to an ignition line of the vehicle. The controller determines whether the ignition input terminal is coupled to an ignition line of the vehicle, and when the terminal is coupled to an ignition line, the controller determines vehicle ignition turn on and ignition turn off events by detecting voltage changes on the ignition line. When the ignition input terminal is not coupled to an ignition line of the vehicle, the controller senses the voltage of the battery of the vehicle to determine vehicle ignition turn on and turn off events based on sensed voltage changes of the battery.
Telematics devices and methods for vehicle speeding detection
Exemplary embodiments are provided of telematics devices and exemplary corresponding methods. In an exemplary embodiment, a telematics device generally includes a controller and a wireless communication module for transmitting data to a remote station. The controller is configured to periodically obtain the speed of a vehicle, determine when the speed of the vehicle has exceeded a first speed threshold, store the monitored speed as a max speed value, and compare each successive monitoring interval speed to a previous monitoring interval speed. When the successive monitoring interval speed is greater than the max speed value, the max speed value is updated. A speeding event occurs when each successive monitoring interval speed is above the first speed threshold for a speed duration, and/or when any successive monitoring interval speed exceeds a second speed threshold.
