A hand-held device includes an audio transducer (i.e., speaker) for delivering acoustic test stimuli to a test subject within the direct sound field range of the device. The device accurately delivers multi-level and multi-frequency test stimuli for the subjective response by the test subject holding the device. An ultrasonic position sensor within the device determines the position of the device with respect to the head or a portion of interest of the head of the test subject while the device is being held. The acoustic test stimuli are controlled and regulated based on the position of the device with respect to the test subject so that accurate levels of test stimuli are presented only when the device is within a proper range and irrespective of its exact position with respect to the test subject's head.

The present invention discloses a method of rating the fruit according to surface colors. Red fruit samples and orange fruit samples are selected respectively to form a red fruit sample unit and an orange fruit sample unit, a fruit sample image without background is obtained, the weighted histogram of the H weight and area of the fruit sample image is calculated and then the principle component is analyzed; the principle components whose variance contribution ratio are before K are selected; when the accumulated variance contribution ratio is larger than 85 percent, the sample central points of the red fruit sample unit and the orange fruit sample unit are calculate respectively, which obtains the principle component central points of two sample units; then the Mahalanobis Distances of DMR and DMY of the red fruit sample unit and the orange fruit sample unit are calculated respectively, if DMR is less than DMY, the test object is red fruit, or else the test object is orange fruit. The present invention overcomes the problem that the practical area represented by each point on the fruit image is not completely coincident, improves the precision of fruit rating according to surface colors, and is able to rate accurately the fruit according to surface colors.

A method is provided to quantify and/or qualify psychological and physiological components of stress in mammals, in which a stimulus can be applied to the test subject's environment during the test. The method involves the steps of measuring one or more physiological and/or psychological characteristics before and after the administration of a stimulus to a test subject. The stimulus may consist of any product, task, aroma or the like that elicits a stress-related response upon administration. By analyzing the resulting measurements, and optionally comparing physiological and psychological characteristics where both are measured, an overall level of stress may be determined. The method of stress measurement may further be used in product development and/or testing.

A shear wave velocity is accurately measured. Time change data of a displacement of a tissue due to a shear wave generated in a test object is calculated from a reception signal obtained by transmitting an ultrasonic wave to the test object and receiving a reflected wave. The time change data of the displacement is converted into spectrum data indicating a displacement distribution in a frequency space having a spatial frequency and a time frequency as two axes. Spectrum data in a predetermined region is extracted by rotating the spectrum data by a predetermined angle in the frequency space, and filtering the rotated spectrum data. A velocity of the shear wave is calculated based on the extracted spectrum data in the predetermined region.
