Abstract: A computing system, method, and computer-readable medium includes a fatigue tracking service that assists with monitoring fatigue damage in a subsea wellhead system. The fatigue tracking service uses historical environmental data to determine a fatigue damage rate. The fatigue tracking service determines a fatigue allowance based upon the fatigue damage rate, a number of days assigned to a well operation, and a total allowable fatigue damage. The fatigue tracking service compares the fatigue allowance to measurements providing an accumulated fatigue damage to facilitate the monitoring of fatigue damage in the subsea wellhead system.

Abstract: An adapter connects to a valve to convert the valve to a uniform configuration for connection to a pump. In one application, a conventional Schrader or Presta valve has an adapter to convert the valve to a uniform configuration for connection to a pump. An attachment head of a pump engages and creates a seal with the adapter and has a release mechanism to disengage the attachment head from the adapter.

Abstract: A helmet buckle having magnetic alignment reduces pinching caused by typical bicycle helmet buckles. The helmet buckle having magnetic alignment includes magnets in a base and a clip that align the parts to each other and help secure the buckle.

Abstract: An adapter connects to a valve to convert the valve of a type, such as but not limited to Schrader or Presta, to a uniform configuration. An attachment head for engages and creates a seal with the adapter and has a release mechanism to disengage the attachment head from the adapter.

Abstract: A connector system for attaching accessories to a bicycle or other sporting good includes a base and a platform. The base is attached to a bicycle and the platform is attached to the accessory, and the base and the platform are held together by mechanical or magnetic forces.
