Definitions
- the present invention relates generally to electrical and electronic hardware, computer software, wired and wireless network communications, and computing devices. More specifically, techniques for component protective overmoldmg using protective external coatings are described.
- Conventional devices typically lack capabilities that can record, store, analyze, communicate, or use data in a contexrually-meaningful, comprehensive, and efficient manner. Further, conventional solutions are often limited to specific individual purposes or uses, demanding that users invest in multiple devices in order to perform different activities (e.g., a sports watch for tracking time and distance, a GPS receiver for monitoring a hike or run, a cyclometer for gathering cycling data, and others). Although a wide range of data and information is available, conventional devices and applications generally fail to provide effective solutions that comprehensively capture data for a given user across numerous disparate activities.
- conventional devices such as fitness watches, heart rate monitors, GPS-enabied fitness monitors, health monitors (e.g., diabetic blood sugar testing units), digital voice recorders, pedometers, altimeters, and other conventional data capture devices are generally manufactured for conditions that occur in a single or small groupings of activities and, subsequently, are limited, in terms of commercial appeal to consumers.

- a final test may also evaluate an item coated with an outer molding for other purposes. If the final test is not passed, then the item may be rejected and. in some examples, the outer molding may be removed and re-applied (i.e., reformed) (610). In other example, a failed final test may also result in the item being rejected and destroyed, recycled, or otherwise handled as unacceptable. Finally, after a final test is performed a visual inspection may be performed to determine whether an item has been covered by the formed outer molding as desired (618). In other examples, process 600 may be implemented differently in the order, function, configuration, or other aspects described and is not limited to the examples shown and described above,
