In accordance with embodiments, methods for the recovery of security credentials of a Bluetooth mesh network are disclosed. A computing device of the Bluetooth mesh network receives user login information, and generates a network key of the Bluetooth mesh network based on the user login information. The computing device generates an application key of a first node to be provisioned based on user login information. A device key is generated using the unicast address of the first node and part of user credentials. The current sequence number is recovered by one of the four techniques depending on the characteristics of the network. The unicast addresses of the nodes are assumed to be sequential and later validated by sending messages. IV index is recovered using processes defined in the Bluetooth mesh standard. After recovery of the above parameters, the mesh network can operate normally using the aforementioned computing device.

Apparatus and methods to reduce effects of erratic motion input during operation of an instrument via a graphical user interface are described. Spatial motion input received from a user may be filtered using filter parameters obtained during a calibration procedure. The filtered motion input may be used to predict a trajectory of a cursor or object used to select an icon or text. The icon or text may be latched to the approaching cursor or object. The combination of motion smoothing and latching may improve ease-of-use of the graphical user interface for individuals having neuromuscular disorder, or users operating instruments in high-vibration environments.
