A system and method for warning a vehicle driver of a potential collision when turning left or right at or near an intersection, where the system and method provide additional analysis to limit false positive and false negative warnings based on specialized circumstances. The method includes determining if the host vehicle is likely to turn at or near the intersection, and obtaining speed, velocity and position data of the host vehicle and any relevant remote vehicles. The method determines a predicted path of the host vehicle and the remote vehicles based on the speed, velocity and position data, and issues a warning to a driver of the host vehicle if the host vehicle and one of the remote vehicles may collide based on the predicted paths. If the host vehicle is in a specialized circumstance, the method provides additional collision analysis to reduce false positive warnings and/or false negative warnings.

Systems and methods for head impact injury prediction. A computer implemented method is provided for event based injury predictions. The computer implemented method receives an indication of sensor data related to an impact of a user. The received sensor data is compared to previously stored sensor data in a data store. Each instance of the previously stored sensor data is associated with a medical diagnosis. If the received sensor data matches any of the previously stored sensor data based on the comparison, then an injury risk indicator is generated based on at least one of the medical diagnosis associated with the matching previously stored sensor data or an impact history of the user.

An integrated golf club and analysis system that measures and analyze the performance characteristics of both: 1) a free golf swing without impact with a golf ball and 2) a golf swing with ball impact analysis. Free swing analysis provides critical information needed to analyze swing style so that dynamics swing characteristics optimization can be evaluated throughout the entire swing without ball impact, while impact analysis provides critical information on ball impact location on the club face, however, they cannot be measured simultaneously since ball impact eliminates the ability to identify the swing metric peaks such as velocity if it were to occur after ball impact. To achieve both, an integrated electronics golf club head comprises multiple types of sensors for measuring club head motion, impact and spatial location information with a weight and balance of a regulation golf club head.
