An approach for monitoring a sleeping subject includes receiving an input for specifying an attachment position of a monitoring device attached to a subject, calibrating a resting positioning of the subject based on the attachment position, analyzing sensor information collected from the monitoring device to determine a movement of the subject into a potentially dangerous position with respect to the calibrated resting position, wherein the monitoring device includes an array of sensors including an accelerometer, one or more biometric sensors, or a combination thereof.

Systems, methods, and devices are disclosed for predictive shimming of large structures. Systems may include a remote device configured to move along a first path relative to a first vehicle structure. The remote device may be configured to move a sensor device along a plurality of measurement points included in the first path. A base device may be configured to identify a position of the sensor device at each measurement point. The base device may be configured to generate measurement data including a first plurality of measurements identifying at least one structural dimension of a first surface of the first vehicle structure. A controller may be configured to control operation of the base device and the remote device based on engineering data associated with the first vehicle structure. The controller may be further configured to determine at least one shim dimension associated with the first surface.
