Abstract: A telematics platform including a telematics service and a telematics device interfacing with an on-board electronic system of a vehicle, performs a compatibility workflow with respect to the vehicle-telematics device compatibility and data accuracy. The compatibility workflow may include multiple phases in which telematics data is assessed for compatibility or inaccuracies based on pre-established compatibility data obtained from a population of other vehicle-telematic device interactions, user-reported compatibility data, and vehicle-specific compatibility data. Incompatibility or inaccuracies in telematics data may be used to activate/deactivate or continue/discontinue interactions between the vehicle and the telematics device, and to inform users of the incompatibility of the vehicle-telematics device pair, or inaccuracies in the telematics data.

Abstract: A walking stick includes a body (10), a handle (20) formed at one end of the body and configured to be grasped by a hand of a user, and a balance structure (60). The balance structure is mounted to a distal end of the handle via screws or hooks or other means. In use, the walking stick acts as a lever in which the hand of the user acts as a fulcrum and the balance structure is pulled downward because of the pull of gravity to facilitate lifting the body of the walking stick. The balance structure may be made of metal, plastic or any other material. The weight of the balance structure may be desired according to demand. The walking stick has a simple structure with low cost and is convenient to users.
