20110142451 | Optoelectronic Switch Transmitter Using Millimeter Wavelength - An optoelectronic switch using millimeter wavelength (MMW) is provided. An r voltage pulse is applied to a device under test (DUT) for switching the photo-generated MMW power The DUT is operated under reverse bias. An optical light source with modulated MMW envelop is injected on to DUT for MMW power generation. Thus, based on change of the reverse bias, speed is violently changed and the MMW optoelectronic switch is thus obtained. | 06-16-2011 |
20110309269 | Photonic Generator of Ultra-Wide Band Millimeter Wave - A photonic generator is provided. The photonic generator uses ultra-wide band millimeter wave (MMW) for generating a high-power ultra-broad band white noise. Thus, the present disclosure can be used for failure detection of instantaneous all-band device, noise detection of instantaneous all-band amplifier and mixer, wide-band cipher transmission, pseudo-random bit generation, ADC dithering of analog-digital converter, saturation power test of wide-band optical communicator, system noise detection of MMW receiver, and gain and phase detection of MMW interferometer. | 12-22-2011 |
20110309459 | Multi-Cascaded Photodiode - The present disclosure uses at least two cascaded photodetectors. Device area is increased to provide a bigger current than a single photodetector under the same bandwidth. Hence, bandwidth efficiency (BRP) and saturation current-bandwidth product (SCBP) are improved for a high speed, a high responsivity and a high bandwidth with simple structure and low cost. | 12-22-2011 |
20120153417 | Laser Power Converter for Data Detection and Optical-to-Electrical Power Generation - The present disclosure provides a high-speed laser power converter (LPC). The LPC is able to be cascaded. The LPC has a high-speed photodiode (PD) performance even operated under a forward bias operational voltage. Thus, the present disclosure can generate power (instead of consume power) during high-speed data transmission in an optical interconnect (OI) system using 850 nano-meters (nm) wavelength vertical cavity surface-emitting laser (VCSEL). | 06-21-2012 |

20080212790 | SOUND EFFECT PROCESSING SYSTEM APPLIED TO COMPUTER - A sound effect processing system applied to a computer includes a sound quality processing unit provided on the computer for processing and modifying sound quality as a signal frequency characteristic of sounds being input to or output from the computer, and a hardware sound quality adjustment control interface, via which a user may directly control the sound effect processing system to adjust sound signal frequencies and improve the sound quality without the need of using any software or driver. | 09-04-2008 |
20080279404 | Surround Sound Headphone - A surround sound headphone has a plurality of sound-producing planes provided in each of the earpieces of the headphone, and at least one diaphragm arranged on each of the sound-producing planes for producing sounds in directions toward a user's ear, such that the sounds produced by the diaphragms converge at a user's ears, enabling the user to experience a stereo and surround sound effect. | 11-13-2008 |
20080304683 | Stereo Sound Image Forward Headphone - A stereo sound image forward headphone is provided. The stereo sound image forward headphone utilizes a speaker provided on the ear hanger, which is spaced apart from a user's ear by a distance, such that sound from the speaker is on the front side of the user's ear. The stereo sound image forward headphone not only creates a natural impression of sound heard from various directions as in natural hearing, but also protects the user's ear from hearing loss which might otherwise result from long use of a headphone. | 12-11-2008 |
20080310658 | Headphone for Sound-Source Compensation and Sound-Image Positioning and Recovery - A headphone for sound-source compensation and sound-image positioning and recovery is provided, including a left speaker device for playing to a left ear of a user left channel sound and right channel sound originating from at least a sound signal, and a right speaker device for playing to a right ear of the user left channel sound and right channel sound originating from the sound signal. A user wearing the headphone of the invention perceives stereo sound field and sound image positioning seemingly provided by a loudspeaker. | 12-18-2008 |
20090252346 | METHOD OF PROCESSING AUDIO FILES - A method of processing audio files includes the steps of providing an audio frequency adjusting section, via which one or more first audio files may be changed in the frequency property thereof to create one or more second audio files without the need of opening the first audio files. In this manner, a plurality of audio files may be easily and quickly modified at one time via the audio frequency adjusting section to shorten the time needed to optimize the tone quality of the audio files. | 10-08-2009 |

20110097611 | BATTERY AND METHOD FOR GENERATING ELECTRICAL POWER USING THE BATTERY - A battery includes: a container; an electrolyte received in the container; and first and second electrodes disposed in the electrolyte and having different electrical potentials upon exposure to the electrolyte. | 04-28-2011 |
20110156381 | STICKY NOTE PAD - A sticky note pad includes at least two stacks of sticky note sheets. Each sticky note sheet has a note-writing region, an index tab region projecting from a right lateral edge thereof, and a removable pressure sensitive adhesive layer provided on a bottom face thereof in proximity to a left lateral edge thereof. The index tab regions of the sticky note sheets of one of the stacks are staggered with respect to the index tab regions of the sticky note sheets of the other stack in a top-to-bottom direction, and are aligned to the same in a direction parallel to the lateral edges of the sticky note sheets. A glue layer binds the left lateral edges of the sticky note sheets of all the stacks. A partition sheet is adhered to the bottom face of a lowermost sticky note sheet of an upper stack. | 06-30-2011 |
20120015174 | NOTE PAD CONTAINING CARBONLESS COLOR-DEVELOPING MATERIAL - A note pad includes: a stack of carbonless note sheets each of which includes: a substrate; and a color-developing coating layer formed on an upper surface of the substrate, and including a plurality of microcapsules and a carbonless color-developing material, each of the microcapsules encapsulating a reactive dye and being breakable, when subjected to a pressure, to release the reactive dye to react with the carbonless color-developing material for color development. | 01-19-2012 |
