Abstract: An electronic device includes a host, a display, a sliding plate, and a keyboard. The host has an operating surface. The display is pivoted to the host. The sliding plate is slidably disposed in the host, where the display is mechanically coupled to the sliding plate, and the sliding plate includes a plat portion and a recess portion that are arranged side by side. The keyboard is integrated to the host. The keyboard includes a key structure, where the key structure includes a key cap and a reciprocating element, and the key cap is exposed from the operating surface of the host. The reciprocating element is disposed between the key cap and the sliding plate and has a first end connected to the key cap and a second end contacting the sliding plate. The second end is located on a sliding path of the plat portion and the recess portion.

Abstract: An optical lighting device includes an optical element having a light incident surface and a light emitting surface, wherein at least one first anamorphic asphere is deployed on either of the light incident surface or the light emitting surface. A first light source being square deployed on one side of the optical element and opposite to the light incident surface.

Abstract: An interface chip with a built-in self-test mechanism. An electrical physical layer (EPHY) provides a signal to a transmission terminal of the interface chip, and gets a signal from a reception terminal of the interface chip. A digital code generator generates a source code to be scrambled as a scrambled code and then encoded by an encoder and conveyed to the EPHY to be converted into the signal that is provided to the transmission terminal by the EPHY. The EPHY further converts the signal received from the reception terminal into a receiving code to be decoded by a decoder as a decoded code and then descrambled by the descrambler as a restored code. When the transmission terminal is coupled back to the interface chip via the reception terminal, the code checker checks whether the restored code matches the source code.

Abstract: A dynamo hub includes a magnet module and a yoke module. The magnet module includes first magnetic pole sections and second magnetic pole sections on opposite sides thereof. The yoke module includes first yoke irons and second yoke irons located on the opposite sides of the magnet module. The first and the second yoke irons are not parallel to the first and the second magnetic pole sections, so that the first and the second magnetic pole sections always cross the first and the second yoke irons in an tilted matter while the magnet module is driven to rotate to reduce the cogging torque when the dynamo hub is running.

Abstract: A laser pen includes a laser diode and a plug. The plug is received in an earphone jack of a portable electronic device. The laser pen obtains power from the portable electronic device to turn on the laser diode.

Abstract: A hub including an up-stream port, at least one down-stream port, a state-determining unit, and a control unit is provided. The up-stream port is configured to be coupled to a host device. The down-stream port is configured to be coupled to at least one peripheral device. The state-determining unit is coupled to the down-stream port and generates a determination result according to a level of a pin of the down-stream port. The control unit is coupled between the up-stream port and the state-determining unit. When the host device sends a sleep request, the control unit determines whether the peripheral device is operating in a specific mode according to the determination result. When the peripheral device is operating in the specific mode, the control unit provides an unready response to the host device.

Abstract: A concealed-type retractable extension cord organizing structure includes a junction box having a front cover plate provided with a fixed socket and a rewinding control button; and at least one movable socket movably mounted on the front cover plate and connected at an inner end to a reel via a power cord. The power cord is normally invisibly wound up in a space provided in the reel. The movable socket and power cord can be pulled out with fingers to an extended position and locked thereto for use. When the rewinding control button is pushed, the power cord is retracted into the junction box and rewound around the reel, so that the movable socket becomes flush with the front cover plate again and the power cord is concealed behind the front cover plate and neatly wound up without occupying extra space.
