Provided is a fluid transportation device and a fluid transportation method in which a transported fluid such as a gas or a liquid can be ejected into a space from an ejection unit and transported locally to a target location distant from the ejection unit while minimizing scattering. The transporting fluid is ejected from an ejection port into a space and thereby forms vortex rings, and the transported fluid is fed to the outside of the transporting fluid at a speed that is lower than that at the center of the transporting fluid, whereby the transported fluid is directly accommodated in the vortex rings formed by the transporting fluid moving in a rolling motion at the ejection port, and transported together with the vortex rings.

A speech is recognized using ACF factors extracted from running autocorrelation functions calculated from the speech. The extracted ACF factors are a W(width of ACF amplitude around zero-delay origin), a W(maximum value of the W), a &#x3c4;(pitch period), a &#x3c6;(pitch strength), and a &#x394;&#x3c6;/&#x394;t (rate of the pitch strength change). Syllables in the speech are identified by comparing the ACF factors with templates stored in a database.

A workspace system includes a working region and a plurality of work surfaces or desktops placed in the working region. The working region provides a first environment suitable for a right hemisphere-dominant job, a second environment suitable for a left hemisphere-dominant job, a third environment different from the first and the second environments, and a seating area in which a job performer takes a seat. Accordingly, the desktops may include a first desktop for the first environment, a second desktop for the second environment, and a third desktop for the third environment. The three working environments are arranged about the seating area. The first, the second and the third desktops are different in e.g. feel, material, shape and color from each other.

A system and method (and storage media) for identifying the category of the source noise and sound by using the physical factors derived from the autocorrelation function (ACF) and the interaural crosscorrelation function (IACF) which are ever changing in the time domain based on the model of human auditory brain function system. A method for evaluating a sound comprises the steps of: using the sound recorder to capture and record the acoustic signal; calculating the ACF from the acoustic signal using a CPU; calculating ACF factors extracted from the calculated ACF using the CPU; and identifying the kinds of the noise based on the ACF factors. Thereby the unknown noise source can be identified what it is (such as automobile noise, and factory noise), and can be identified its type such as type of cars or type of machines.

Method for evaluating sound and system for carrying out the same

A sound reproducing apparatus is capable of reproducing a stereo or a voice signal and adding thereto effect sounds, such as an initial reflected sound, and reechoed sound during the reproducing. Each of the effect sounds is added with a delay time depending on a change of the sound source signal. To obtain the delay time, the sound source signal is converted into a three-value signal, and then the time in which the auto-correlation of the three-value signal decreases to a predetermined value is determined. Thus the effect sounds can be added automatically with a desired delay time due to the sound source signal. Therefore manual adjustments are unnecessary, and the circuit structures of the entire apparatus can be simplified.
