Abstract: A braille reading-writing device includes a body and a plurality of braille buttons. The body has a first surface and a second surface. The braille buttons are disposed through the body. Each of the braille buttons includes a pressing portion located at the same side with the first surface and a touching portion located at the same side with the second surface. The touching portion protrudes from the second surface when the pressing portion is pressed. The braille reading-writing device allows the blind people to write braille on the first surface and to touch to read the written braille on the second surface, thereby integrating the functions of writing and reading braille.

Abstract: A movable touch module and an electronic device using the same are provided. The movable touch module is disposed at a main body. The movable touch module includes a movable element, a touch unit, a plurality of elastic elements, at least four movement sensing elements, and at least two rotation sensing elements. The movable element is disposed at the main body and is movable relative to the main body on a plane. The touch unit is fastened to movable element. The elastic elements are fastened to the main body and are against the periphery of the movable element. The movement sensing elements are fastened to the main body and are located around the movable element. The rotation sensing elements are fastened to the main body.

Abstract: This invention provides a light emitting device with variable volume. The light emitting device includes a main body with variable volume, a sensor, a light emitting element, and a controller. The sensor is disposed in the main body for generating a volume measuring signal. The light emitting element is disposed in the main body. The controller is coupled with the light emitting element and the sensor. The controller controls brightness of the light emitting element according to the volume measuring signal.

Abstract: A portable electronic device having an illuminated keyboard includes a display having a recessed portion and a main body pivotally connected with the display. The main body includes a casing, a keyboard, a fastening element, and a plurality of light-emitting elements. The keyboard is disposed at the casing and includes a plurality of keys made of a first light-transmitting material. Each key has a light incident surface and a light output surface. The fastening element is fastened to the casing and has a first portion made of a second light-transmitting material. The fastening element corresponds to the recessed portion. The light-emitting elements are disposed in the fastening element. The light emitted by the light-emitting elements passes through the first portion of the fastening element to directly enter into the key through the light incident surface and to be outputted from the key through the light output surface.

Abstract: This invention provides a connector socket and a portable electronic device using the same. The connector socket is disposed at a casing for connecting a connector. The connector socket includes a rotatable element and an elastic element. The rotatable element is pivotally connected to the casing. The elastic element is coupled to the casing and the rotatable element. The rotatable element has a protrudent portion. When the connector is connected to the connector socket, the connector presses the protrudent portion to allow the rotatable element to automatically rotate from a storage position to an open position. When the connector is separated from the connector socket, the rotatable element automatically rotates from the open position to the storage position via the elastic element.

Abstract: This invention provides an electronic device capable of being connected with an external device. The electronic device includes a first connecting port, an adapting element, and a casing. The first connecting port is disposed at the casing. The adapting element has a second connecting port and a connector. The size of the second connecting port is greater than that of the first connecting port. The casing has a containing space for containing the adapting element. When the electronic device is connected with the external device, the adapting element is separated from the containing space, the connector is connected with the first connecting port, and the second connecting port is connected with the external device.
