A method, apparatus, and computer-readable storage media for managing orphan tokens in a business process system. A trained model-based pattern classification system analyzes the periphery sensor data and makes a probabilistic prediction of the user’s hand size. The tension coil spring pivots together with the bolt and the adjusting and locking nuts relative to the bracket. This greatly simplifies and shortens the implantation protocol while substantially reducing undesirable mechanical stresses within the implant at these attachment points, thereby increasing the useful life of the implanted medical device. When bringing into contact with each other, the restricting members make contact at the outside diameter portions thereof. The device is particularly useful for manoeuvring stakes, such as sheet piles and the like.
