Abstract: An electronic device and item information providing are provided. The electronic device includes a communication module configured to receive item information of at least one item from a management server, a display configured to display a user interface including the item information, an input module configured to receive a user input selecting an item from among the displayed item information, a sensor module configured to collect motion data of the electronic device, and a control module configured to check a mission corresponding to the selected item and to transmit mission performance information, obtained based on the motion data, to the management server through the communication module.

Abstract: An apparatus which holds an optical fiber in alignment to an optical device includes a fiber holder having a first plurality of indentations, an optical fiber held within one of the first plurality of indentations, a base substrate having a second plurality of indentations formed in a top surface of the base, a plurality of spacers, each of the plurality of spacers held within one of the second plurality of indentations and an optical device mounted on the base. The fiber holder is mounted on the base with the plurality of spacers within the first plurality of indentations.

Abstract: An actuator for controlling a pitch angle and a yaw angle of a mirror in a fiber-optic switch includes a piezoelectric strip having a first and second arm. The first arm extends from a substrate in a first direction. The second arm, which is for attachment to the mirror, extends from the first arm in a second direction different from the first direction. A pitch-electrode, in electrical communication with the first arm, controls pitch angle by causing deflection of the first arm. A yaw-electrode, in electrical communication with the second arm, controls the yaw angle by deflecting the second arm.
