Abstract: A pair of glasses includes a frame and a pair of temples. The frame can hold lenses in front of a person's eyes while the pair of temples can rest over the person's ears. A tester for endurance testing of the pair of glasses, includes: a frame holder disposed vertically on a horizontal base plate, the frame holder configured to secure the pair of glasses in a test position with the pair of temples extending from the frame holder horizontally in a space above the base plate, the pair of temples having an inter-temple separation distance; and a pair of motorized pushers configured to contact and displace each of the pair of temples simultaneously toward or away from the other temple in the pair of temples.

Abstract: This disclosure is directed to a test fixture to test a robustness of a connection port of an electronic device, a cable connector coupled to the connection port, or both. The test fixture may enable repeatable testing using predetermined test parameters. The test fixture may secure the electronic device using a clamp. A pendulum may be mounted in the test fixture and rotatable to cause an impact of a weight against a cable connector coupled to the connection port of an electronic device. After the impact, the integrity and/or functionality of the cable connector, the connection port, or both may be inspected. In accordance with one or more embodiments, the test fixture may be under at least partial control of a controller. The controller may enable creation or control of test parameters, repeat testing, cycle testing, and/or inspection (e.g., determining whether the connection is maintained and/or functional, etc.).

Abstract: Some examples include an energy harvester for use in an electronic device to convert mechanical energy associated with vibrations of the electronic device into electrical energy. For instance, an energy harvester including rows of piezoelectric cantilevers may be arranged around a proof mass and may be utilized to convert the vibrations into electrical energy. In some examples, the energy harvester may include an electromagnetic energy harvester in addition to, or in place of the piezoelectric energy harvester.
