A phased array antenna comprises a plurality of unit cells arranged in an array. Each of the plurality of unit cells comprises: at least one radiating element receiving a feed signal and radiating a signal; and two path changeover switches for transmitting the applied feed signal as it is or as a distribution to the at least one radiating element, or at least one unit cell disposed adjacent, under control of an antenna control circuit.

Scalable and reconfigurable phased array antenna and method for manufacturing the same

The present invention discloses a pump for measuring a pressure of fluid to be transferred, a fluid transport system using the same, and a method for operating the system. The pump includes a pumping portion alternately generating a positive pressure and a negative pressure; a first diaphragm which is provided on one side of the pumping portion and of which a shape is changed as the positive pressure and the negative pressure are alternately generated; a transport chamber which sucks and discharges a transport target fluid corresponding to the deformation of the first diaphragm; a second diaphragm which is provided on the other side of the pumping portion; a monitoring chamber which is provided on one side of the second diaphragm and of which a pressure changes corresponding to the deformation of the second diaphragm; and a pressure measuring portion measuring a pressure change of the monitoring chamber.

A near field communication (NFC) device includes a communications module and a controller. The communications module includes a receiver to receive a wireless signal, a transmitter to transmit data by superimposing the data on the wireless signal, and a signal detector to compare the wireless signal with a predetermined reference signal. The communications module operates in at least one of a wakeup mode and a sleep mode, the receiver and transmitter are activated to operate in wakeup mode, and the receiver and transmitter are deactivated in sleep mode. The controller adjusts the sensitivity of the signal detector based on a magnitude of the wireless signal and an operating condition of the communications module when the communications module enters the wakeup mode from the sleep mode.

Near field communication device

Disclosed herein is an image display apparatus including a storage unit storing a plurality of images, an input unit receiving a selection command for selecting one or more images from among the plurality of images, and a display unit displaying at least one image of the selected images in a first zone and at least one second image of the selected images in a second zone.

Apparatus and method for displaying images

The invention provides a multilayered device and the method for fabricating the same. The multilayered device comprises a substrate, a first layer deposited on the substrate, a second layer deposited on the first layer, and a third layer deposited on the second layer. The coverage of the second layer is determined by a rate of crystallization of the third layer. The rate of crystallization of the third layer is determined by measuring X-ray diffraction of the device.

Device having a multilayered structure and method of fabricating thereof

Micro-mirror device and an optical pick-up system of the same, the optical pick up system including a light source module for emitting a light, a first and a second focusing parts for focusing the light emitted from the light source module onto a surface of an optical recording medium, and a micro-mirror device between the first and second focusing parts for fine adjustment of a position of the light incident through the first focusing part, reflecting to the optical recording medium through the second focusing part, sensing the light re-reflected at the optical recording medium, and converting into an electrical signal, thereby permitting fabrication of a micro optical system by integrating/packing optical components, such as the mirror, the optical signal detecting photodiode, and the beam positioning device, saving a production cost by using silicon semiconductor fabrication process and micro-machining, and enhancing a positioning preciseness of the light by coupling micro actuator for driving the mirror.
