Abstract: A storable multi-functional exercise apparatus is provided. The storable multi-functional exercise apparatus includes a main body, a first seat that is disposed on the main body, and at least one resistance mechanism. The resistance mechanism includes a damping module, a fixing sleeve, and a rod body. The fixing sleeve is connected to one end of the rod body, the fixing sleeve has a fixing hole, and the damping module is disposed in the fixing hole. The rod body is movably disposed on the main body, so that the fixing sleeve and the damping module are configured to move out of the main body or be stored in the main body.

Abstract: An unmanned aerial vehicle (UAV) including a vehicle body and an airflow thruster is provided. The vehicle body has a center hub, an airflow guiding structure and an outer circumferential portion. An interior of the airflow guiding structure is interconnected between the center hub and the outer circumferential portion. The center hub has an airflow inlet. The outer circumferential portion has a plurality of lateral guiding outlets facing downward and corresponding to a gravity direction of the gravity direction of the unmanned aerial vehicle. The airflow thruster is disposed inside the center hub for generating a plurality of jet streams, such that the jet streams flow to the lateral guiding outlets through the airflow guiding structure to generate a propulsion.

Abstract: A wearable electronic device includes a host, a wearing member, and a backup power module. The host includes a functional module, a main power module, and an electrical connection port. The main power module is configured to supply power to the functional module. The electrical connection port is electrically connected to the main power module. The wearing member is connected to the host. The backup power module is detachably disposed at an upper region or a surrounding region of the host to electrically couple the electrical connection port, or is detachably disposed on the wearing member and configured to electrically couple the electrical connection port to supply power to the main power module.
