Abstract:
The present invention relates to a sound-transmitting display panel for outputting a sound corresponding to the coordinates of an object in a scene. The display panel according to the present invention comprises: a plurality of pixels; a plurality of holes formed with a uniform density on the display panel to transmit the sound generated by a speaker arranged behind the display panel; and a driving circuit for driving the display panel.
Abstract:
A method is provided for fabricating a nanochannel. The method comprises providing a microchannel and controlling collapse of the microchannel so that it collapses to form a nanochannel of desired dimensions. The method employs a collapsible, flexible material such as the elastomer polydimethylsiloxane (PDMS) to form the nanochannel. A master is provided that is configured to have geometric conditions that promote a desired frequency of microchannel collapse. A collapsible material having a stiffness that also promotes a desired frequency of microchannel collapse is molded on the master. The molded collapsible material is removed from the master and bonded to a base, thereby forming the microchannel, which then collapses (or is collapsed) to form the nanochannel of desired dimensions. Nanofluidic and microfluidic devices comprising complex nanochannel structures and micro to nanochannel transitions are also provided.
Abstract:
The present invention relates to an acupuncture device and to a therapeutic method using the same, and more particularly relates to a medical acupuncture device which smoothly regenerates skin tissue by rapidly and easily introducing a cosmetic liquid or drug as far as the dermic layer in the skin of the face or the like and relates to a therapeutic method using the same. More specifically, the medical acupuncture device according to the present invention comprises: a housing having a bolt hole formed to pass through vertically, and a receiving part which is formed at the lower part of the bolt hole and is linked to the bolt hole; an adjusting bolt which is provided inserted into the bolt hole and can be rotated forwards and backwards, and of which the length projecting from the bottom part of the housing can be adjusted; and a fine needle coupled to the bottom part of the adjusting bolt.
Abstract:
The invention relates to a display device with object-oriented stereo sound coordinate display, which outputs sound, in cooperation with the content of an object being displayed on the screen of the display device, from a speaker corresponding to the coordinates of the object, the speaker being one of a multiplicity of small speakers at the back of the display that constitute a matrix speaker system. In an embodiment of the invention, a display device equipped with a surround speaker system, a player for outputting an image and a display monitor comprises: a center channel decoder which receives audio corresponding to the center channel speaker among audios that are output from a surround decoder of the surround speaker system and which divides the audio into sound sources by object; a center channel matrix which sets coordinates for the sound sources having been divided by object through the center channel decoder; a matrix amp which amplifies the output sound of the speaker in response to each coordinate of the sound sources by object; and a multiplicity of speakers arranged in a matrix form at the back of the display monitor.
Abstract:
The present invention relates to an apparatus for controlling the moving force of cone paper which propagates sound to enhance tone quality of a visual speaker and a flexible OLED covering the cone paper. The visual speaker includes a voice coil, a magnet, an edge, a unit enclosure, a flexible OLED for displaying video images, and speaker cone paper. The speaker cone paper for propagating sound, the flexible OLED covering the speaker cone paper, the edge and the unit enclosure are configured into a closed structure filled with compressed gas. The visual speaker further includes a compression piston and a compressed gas regulator for regulating the pressure of the compressed gas in the closed structure, thereby controlling the moving force of the flexible OLED and the speaker cone paper.
