20090039587 | Automatic Paper Feed Device - An automatic paper feed device is disposed in a machine with a plurality of paper feed slots and comprises a paper storing unit having a plurality of inclined paper feed trays or paper feed slots, and a paper stopping unit which is mounted before the joint of a paper feed roller and the inclined paper feed trays or the paper feed slots. A driving member controls the movement of the paper stopping unit, and the paper stopping unit moves at a lower portion of the papers to be fed. By such arrangements, the papers fed at different inclinations and in different orders will be stopped by the paper stopping unit, and then will be released according to the predetermined order of the paper feed trays, so as to avoid the problem of paper jam. | 02-12-2009 |
20100213665 | TORQUE LIMITING ROLLER AND MEDIUM SEPARATING MECHANISM USING THE SAME - A torque limiting roller includes a shaft, a frictional unit, a roller assembly, a fixing unit and an elastic unit. The shaft includes a first end and a second end. The frictional unit is mounted on the first end of the shaft. The roller assembly is rotatably mounted on the shaft and includes a first end and a second end. The first end of the roller assembly is in frictional contact with the frictional unit. The fixing unit is mounted on the second end of the shaft. The elastic unit is mounted on the shaft, disposed between the fixing unit and the roller assembly, and contacts with the second end of the roller assembly and the fixing unit to provide a normal force between the roller assembly and the frictional unit and thus to provide limiting torque. A medium separating mechanism using the torque limiting roller is also disclosed. | 08-26-2010 |
20140178083 | DETECTION DEVICE FOR DETECTING STATE OF WASTE TONER CONTAINER AND IMAGE FORMING APPARATUS USING SUCH DETECTION DEVICE - A detection device for detecting a state of a waste toner container comprises an optical sensor and an actuation member. The optical sensor comprises an emitting unit emitting an optical signal and a receiving unit receiving the optical signal. A space is provided between the emitting and receiving units, and the optical signal travels along an optical path from the emitting unit to the receiving unit. The actuation member is movably disposed between the emitting and receiving units. The actuation member in a first position interrupts the optical path of the optical signal; and the actuation member is moved by the waste toner container to a second position when at least a part of the waste toner container is placed in the space. The actuation member in the second position allows a passage of the optical signal. An image forming apparatus using such a detection device is also provided. | 06-26-2014 |

20090070108 | METHOD AND SYSTEM FOR IDENTIFYING SPEECH SOUND AND NON-SPEECH SOUND IN AN ENVIRONMENT - In a method and system for identifying speech sound and non-speech sound in an environment, a speech signal and other non-speech signals are identified from a mixed sound source having a plurality of channels. The method includes the following steps: (a) using a blind source separation (BSS) unit to separate the mixed sound source into a plurality of sound signals; (b) storing spectrum of each of the sound signals; (c) calculating spectrum fluctuation of each of the sound signals in accordance with stored past spectrum information and current spectrum information sent from the blind source separation unit; and (d) identifying one of the sound signals that has a largest spectrum fluctuation as the speech signal. | 03-12-2009 |
20090322559 | WARNING SOUND DIRECTION DETECTING APPARATUS - A direction detecting apparatus is adapted for installation on a vehicle, and includes a first sound collecting unit, a second sound collecting unit, an identifying unit, a direction estimating unit, and a notifying unit. The first and second sound collecting units collect sounds from roads. The identifying unit identifies the types of the sounds collected by the first and second sound collecting units. The direction estimating unit determines whether a warning sound comes from the front when the sound type identified by the identifying unit is a warning sound. The direction estimating unit estimates the direction of the warning sound when the warning sound comes from the front, and estimates a lane in which the warning sound is located when the warning sound comes from behind. The notifying unit is for providing notification of the estimation result of the direction estimating unit. | 12-31-2009 |
20100290633 | METHOD AND APPARATUS FOR AUTOMATIC NOISE COMPENSATION USED WITH AUDIO REPRODUCTION EQUIPMENT - A method and an apparatus for automatic noise compensation used with audio reproduction equipment are provided. The method comprises: (a) collecting a plurality of mixed audio signals, each mixed audio signal including equipment sound output by the audio reproduction equipment, and background noise; (b) removing the equipment sound from the mixed audio signals to obtain the background noise therein; (c) determining whether or not a plurality of mixed audio signals under inspection include a significant sound; and (d) adjusting the volume of the audio reproduction equipment according to whether or not a significant sound has been generated in the surrounding area and the magnitude of the background noise in the mixed audio signals under inspection to satisfy a plurality of predetermined compensation conditions. | 11-18-2010 |
