Abstract: The present invention is to provide an inflatable bag comprising an airtight container, a cavity and a light-emitting unit. The cavity is formed at a top of the container. The cavity comprises a top opening flush with the top of the container, the opening being in communication with the container and the external. The light-emitting unit is mounted in the cavity by inserting through the opening. The light-emitting unit comprises a battery, a light-emitting member provided at a bottom in the cavity distal the opening, and a switch provided at a top projecting from the cavity. The battery is not electrically connected to the light-emitting member after inflating the container to a predetermined shape. The bag is adapted to emit light only by pressing the switch projected from the container to electrically connect the battery to the light-emitting member.

Abstract: An intuitive image navigator is described. The intuitive image navigator comprises a direction control device and a rotational control ring. The image direction control device moves an image shown on a display of an electronic device, for example, an electronic map on a display of a portable electronic device. The rotational control ring is configured around the image direction control device to control the display condition of the image on the display. The image direction control device provides an intuitive omni-directional variable-speed scrolling function and the rotational control ring provides a stepless variable-speed changing function for browsing the image.
