Abstract: A wrist-worn device includes a main body having one of a retention recess and a retention projection and a bezel configured to cover at least a portion of the main body. The bezel has one other of the retention recess and the retention projection. The at least one retention projection engages with the at least one retention recess to removably attach the bezel to the main body.

Abstract: Methods and systems for accurately tracking medical devices using a two-dimensional (2D) matrix code are disclosed. Scan data, location data, and status data may be received by a processor. The scan data may comprise identification information corresponding to a medical device; the location data may comprise location information corresponding to the medical device; and the status data may comprise status information corresponding to the medical device. Once the scan data, location data, and status data has been received, the scan data, the location data and the status data may be stored. Next, at least one medical-device characteristic may be determined, based on at least the scan data and the status data, and once the medical-device characteristic is determined, the medical-device characteristic may be displayed on a graphical display.
