The invention seeks to improve the taking of physical measurements on an industrial product represented by organoleptic perceptions, the method providing a measurement interface that submits descriptors in a relative arrangement such that testers are not influenced by the order in which they appear, regardless of the descriptor and regardless of the field of the descriptor. For this purpose, the invention provides a method of analyzing industrial products in order to characterize them, in order to distinguish between them, and / or in order to modify them so as to improve them, by analyzing the responses of a panel of testers in application of certain descriptors. The method comprises steps consisting in selecting descriptors that are a priori pertinent for determining the organoleptic characteristics of the products; selecting a response mode; providing all of the descriptors simultaneously to the panel of testers on a single occasion and for a determined duration in a measurement interface presenting a center and an input zone for each descriptor, the input zones being distributed uniformly over at least a section of at least one conic about the center of the interface; collecting the responses from each tester as a function of the selected response mode; recording the responses; and analyzing the responses using at least one statistical method.

Local oscillator leakage control in direct conversion processes
InactiveUS6960962B2Automatic scanning with simultaneous frequency displaySpatial transmit diversityIntermediate frequencyLocal oscillator
A system and method for generating a local oscillator (LO) frequency in a zero intermediate frequency (IF) receiver or transmitter is presented. A signal is received from a voltage controlled oscillator (VCO). The signal has a VCO frequency. The VCO frequency is divided by a number N to produce a signal having a divided-down frequency. The signal having the VCO frequency is then mixed with the signal having the divided-down frequency to produce an output signal having an output frequency. Local oscillator leakage is reduced. Thus, the receiver or transmitter may operate in multiple wireless communication bands and modes and meet the associated specifications.
