Title: A method for matching a colour formulation
Inventor: KETTLER WILHELM
IPC: C09D7/80
Filed: 1997-09-09
Abstract: This invention relates to a method for matching a colour formulation to a colour shade model in the field of a colour- and/or effect-imparting surface coating. The reflecting surface of a colour shade, which is to be rematched, of a coloured surface coating is determined metrologically over the visible spectral region using a goniometric spectral photometer with variation of the angle of measurement. The associated standard tristimulus values and/or the vectors in the CIELAB colour solid which are derived therefrom are calculated from the measured reflection factors or spectral energy factors. Those formulations and/or colour shades which exhibit reflection properties or properties derived therefrom which are the most similar to the measured colour shade model are subsequently identified from a formulation database by means of the reflection spectra or the colorimetric dimensional numbers derived therefrom. By means of a computer-generated effect matrix, the metrologically determined, angle-dependent colour difference between the desired colour shade, i.e. the colour shade to be rematched, and the actual colour shade, i.e. the colour shade corresponding to the nearest formulation from the formulation database, is minimised by means of a computer algorithm for function minimisation taking into consideration secondary conditions in the sense of the L2 standard, and a corrected formulation is produced.

Abstract: L'invention concerne un procédé et un appareil permettant d'effectuer de manière fiable un transfert d'un système à accès multiple par différence de code, en utilisant un signal pilote, vers un système utilisant une autre technique d'accès. On ajoute un simple boîtier de circuits pilotes (350) à un ensemble de postes de base (C2A - C2R) situés en bordure. Les postes de base (C2A - C2R) situés en bordure sont des postes de base qui fonctionnent uniquement avec l'autre technique d'accès et qui ont des zones de couverture qui sont contiguës aux zones de couverture des postes de base utilisant le système (AMDC). L'unité mobile surveille le signal pilote des postes de base (C2A - C2R) situés en bordure de la même manière qu'elle surveille les signaux pilotes des postes de base (C1A - C1S) fonctionnant avec le système contrôleur. Quand une unité mobile détecte le signal pilote correspondant à un poste de base (C2A - C2R) situé en bordure, elle notifie un contrôleur (202) du système par une opération standard. Le contrôleur (202) du système est informé de ce que le signal pilote correspond à un poste de base (C2A - C2R) situé en bordure et déclenche ainsi en réponse un processus de transfert "imposé" sur un système utilisant une autre technique d'accès.

IPC: G06T15/00
Filed: 1997-10-06
Abstract: A multi-pass algorithm for applying a perspective transform to quadrilateral images by means of at least two phases of 1-dimensional resampling processes for each dimension. Each phase constitutes a perspective transform from a rectangle to a trapezoid with parallel sides parallel to the corresponding sides of the rectangle. More particularly, each phase comprises a foreshortening pass in one dimension (vertical for parallel horizontal sides, horizontal for parallel vertical sides) followed by a trapezoidal pseudo-shear pass in the other dimension. Thus, in the first phase, the source rectangle is transformed to a first, intermediate trapezoid with either parallel horizontal or parallel vertical sides. In the second phase, the bounding box of this intermediate trapezoid (i. e ., the smallest axis-aligned rectangle containing the trapezoid) is transformed to a second, target trapezoid with either parallel vertical or parallel horizontal sides (i. e., the opposite of the intermediate trapezoid) that bounds the final quadrilateral. Thus, by so transforming the bounding box of the intermediate trapezoid, the corners of the intermediate trapezoid are mapped to the corners of the target quadrilateral. The invention has two advantages over the prior art processes: although some complex calculations have to be performed for each row or column, the per pixel calculations are much simpler; and since the shape of the result is a simple trapezoid (remembering that a rectangle is a trapezoid) at each step, it is easy to control the resampling process to ensure that these shapes are achieved and the result appears stable.

Abstract: A semiconductor chip (105') is stuck to a substrate (412) with an organic adhesive layer (409) containing conductive particles (406) and electrodes (412) are electrically connected to pads (405) through the particles (406). The chip (105') is produced by a method of rotating at a high speed or horizontally reciprocally moving a semiconductor wafer (105) stuck on a tape (107) to flow etchant on the semiconductor wafer (105) rapidly and horizontally, etching uniformly the semiconductor wafer (105) by the etchant to thin the wafer (105), and dicing the wafer (105) into chips. The thin semiconductor chip (150) is stuck to the substrate (102) by heating and pressing the chip (105') to the substrate (102) by using a heating head (106). Therefore, the semiconductor chip (105') is stably produced at a low cost and is stuck to the substrate (412) without causing cracks in the chip and, as a result, a thin semiconductor device which is hardly destroyed by external bending stresses is obtained.

Abstract: A device for regulating sound level of audio systems and noise level of machinery as a function of the desired human auditory level. In the case of audio systems, the produced sound from the speakers is collected by a microphone and measured by a sound level meter in decibels and converted to electrical signal and by the use of a computation process of a computer, the electrical signal is then sent to the damper selector switch which averages the signal value over periods of time and sends the stabilized signal to the comparator unit. The desired human auditory level is selected on the sound level selector switch which generates a proportional signal and send it to the comparator as a reference level. The comparator compares the signal received from the damper selector switch to the reference line generated by the signal from the sound level selector switch. If the signal value from the damper selector switch is higher than the signal value from the sound level selector switch, the comparator sends a signal to decrease the volume control until the signal from the damper selector switch is equal to the signal from the sound level selector switch. If the signal value from the damper selector switch is lower than the signal value from the sound level selector switch, the comparator sends a signal to increase the volume control at a much slower rate than decreasing it until the damper signal is equal to the sound level selector switch. If the signal value from the damper selector switch is equal to the signal value of the sound level selector switch then the signal is disabled. In the case of machinery circuit it is similar to the audio system circuit with minor differences.
