摘要:
A face portion detection device, a behavior content classification device, a speech content classification device, a car navigation system, a face direction classification device, a face portion detection device control program, a behavior content classification device control program, a face portion detection device control method, and a behavior content classification device control method are provided for appropriately classifying a behavior content of the object person from a captured image including the face of the object person. A speech section detection device 1 includes an image capturing unit 10, a data storage unit 11, an image processing unit 12, a lip region detection unit 13, feature extraction unit 14, and a speech section detection unit 15. The lip region detection unit 13 uses a dedicated SVM to detect a lip region from a captured image, and the speech section detection unit 15 uses features of an image of a detected lip region and a dedicated HMM to detect a speech section.
摘要:
A data communication apparatus is provided with a VoIP processor and a modem that interchangeably executes a standard communication mode and a high-speed communication mode, the standard communication mode exchanging the voice packet at a predetermined transfer rate, the high-speed communication mode exchanging the voice packet at a rate faster than the rate of the standard communication mode. When capability information of an opposing apparatus is obtained, in accordance with a predetermined communication protocol, and it is detected that the opposing apparatus has the high-speed communication mode, the high-speed communication mode is selected for execution.

Robbery of a vehicle-mount electric apparatus can be prevented by only driving an operation panel to turn it upside down. The operation panel is disposed in front of the main body of the vehicle-mount audio apparatus, and is moved while being rotated about its rotary shaft. The operation panel moves between first and second states. In the first state, the normally used surface of the operation panel is used as the front surface of the apparatus, and in the second state, the surface other than the normally used surface is used as the front surface. When the operation panel takes generally a horizontal state during the motion of the operation panel 5, the rotary shaft thereof is positioned at one end of the motion range of the operation panel. A drive mechanism chassis for supporting a mechanism for driving the operation panel is supported by horizontal guide grooves of a fixed chassis movably in the horizontal direction, and the horizontal motion of the rotary shaft of the operation panel is regulated by a horizontal guide groove of the fixed chassis.
摘要:
A hypertext document and anchor sentences of parent documents for the hypertext document are registered with an hypertext document identifier as document information for each of hypertext documents having reference relationships with each other. A user can refer to one hypertext document according to an anchor sentence of another hypertext document functioning as a parent document. Also, occurrence positions of one word in hypertext documents and parent documents are registered as word information for each of words. When a keyword is input, a plurality of particular hypertext documents and particular parent documents in which the keyword appears are specified according to the word information, one particular hypertext document and corresponding particular parent documents are unified to a unified hypertext document for each particular hypertext document, an occurrence frequency of the keyword in each unified hypertext document is calculated according to the document information, importance degrees of the unified hypertext documents are calculated as those of the particular hypertext documents according to the occurrence frequencies, and ranking of the particular hypertext documents are determined according to those importance degrees. Because the occurrence frequency is calculated by considering the parent documents, the particular hypertext documents can be appropriately ranked.
摘要:
There is provided an improved electrophotographic image-forming method in which a image-bearing member is charged by brushing a surface of the image-bearing member with a magnetic brush of a charging material containing a magnetic carrier having a volume specific resistance of less than 10.sup.5 .OMEGA..multidot.cm. The present method causes no air pollution including generation of undesired by-products such as ozone, NOx, etc. The present method provides a toner image having high quality such as high resolution and high density without fogging on a background area of a recording sheet.

A cylindrical permanent magnet suitable for use as the rotor magnet of a stepping motor. The magnet is a sintered cylindrical permanent magnet having a composition expressed by MO.nFe.sub.2 O.sub.3, where M represents Ba, Sr, Pb or mixture thereof, while n represents a value of 5 to 6. The sintered cylindrical permanent magnet is provided on its surface with multipolar anisotropy of more than 8 (eight) magnetic poles. Disclosed also is a method of producing the cylindrical permanent magnet.
摘要:
A sound attenuator has at least one sound absorber composed of a hollow body of a hard porous material and an outer or inner layer of air, and exhibits good sound-absorbing property even in a low frequency range, even if the hollow body has a small wall thickness. The hollow body may be provided with projections or a semicircular or otherwise shaped part or parts, or both, serving to maintain the outer or inner layer of air in proper shape. The device is inexpensive and yet is very reliable in quality. When the device is long, the projections in linear form are particularly useful for restraining any flanking transmission of noise and thereby enabling the device to achieve a higher rate of attenuation per unit length. The sound-absorbing property of the device can be controlled over a wide range of frequencies if the hollow body has a porosity varying continuously in a specific direction. The device exhibits an improved sound-absorbing property particularly in a low frequency range if the hollow body is provided with a skin layer on its wall surface facing an air passage.
摘要:
A coffee mill comprises a coffee bean pulverizing cutter held in a mill casing, a space for catching skin slivers and fine fragments of coffee beans and a cutter receiving space communicated with the catching space. Air flow is produced between these spaces during pulverizing the coffee beans to move the skin slivers to the catching space.
