Abstract: A cover with an angle adjustable standing slot is used to place an electronic device. The cover includes a keyboard, a cradle with a standing slot, a torque structure, and an elastic structure. The electronic device can be placed to the standing slot. A user can push the electronic device to rotate the cradle and the cradle would force the torque structure and the elastic structure to move. The electronic device can be stopped at an appropriate viewing angle, because the force between the electronic device, the torque structure, and the elastic structure are balanced. Additionally, the user can use the keyboard on the cover to type or edit documents anytime and anywhere.

Abstract: A self-alignment filling level detecting device has a reflector and a sensor detachable from each other. The sensor has a light emitter, a light sensor, and a controller. The light sensor receives different light intensities when the reflector is assembled to the sensor and when the reflector is not assembled to the sensor. Thus, the controller determines whether the reflector has been accurately engaged and aligned with the sensor or not based on sensing results of the light sensor. Since the reflector and the sensor are detachable from each other, either the reflector or the sensor can be replaced individually if any one of them malfunctions.
