IPC: A61B3/12

Abstract: An ophthalmological diagnosis method is provided in which a laser beam is projected at a region (13b) of the eye fundus to produce a laser speckle pattern formed by light scattered from tissues of the eye fundus. Movement of the speckle pattern (20) is detected to produce a speckle signal which is photon-counted as photoelectric pulses per unit sampling time (Δt). The counted data are stored in a computer memory (57) as time series data over the measurement time. The stored data are then processed to provide a correlation function using different delay times (Δτ) and are also divided per unit time (U1,U2...). For the divided data, the correlation function or variance (σ) is calculated for each unit time. Such an arrangement makes it possible to accomplish accurate evaluation even when there is movement of the eye fundus and thus ensures that measurement data are fully utilized to provide accurate ophthalmological diagnosis.

Abstract: A solvent recovery system comprises a flotation-type coating oven for evaporating solvent from a coating on a film, the oven including a bed of nitrogen vapor for supporting the film and discharging a vapor stream including the nitrogen vapor and the solvent vapor. A vapor phase molecular sieve means dries the vapor stream from the oven and discharges a dried vapor stream. Condensation-type solvent recovery heat exchangers condense the solvent vapor in the dried vapor stream from the sieve and discharge nitrogen vapor and liquid solvent separately. A cryogenic vaporizer converts liquid nitrogen to nitrogen vapor with heat from a heat exchange fluid in heat exchange relationship with the liquid nitrogen. The heat exchange fluid from the vaporizer passes through the solvent recovery heat exchangers in heat exchange relationship with the dried vapor stream therein to cool the same.

Abstract: The invention relates to redundancy circuits for memories in an integrated circuit. It applies to the memories comprising several amplifiers (AOa, AOb; etc.) per data contact (PO, etc). In order to increase the redundancy possibilities with a given number of redundancy columns (CRO, etc), without in any way encumbering the space close to the memory area by complex multiplexers, the following idea is proposed: the address AP which serves for selecting a single amplifier for each contact is also used for selecting a group of memories from among several groups (as many groups as amplifiers per contact) in a storage register for defective addresses. Only the defective addresses of this group are applied to a comparator (COMP) serving to detect if a defective column address is received by the memory. Thus is established a correlation between the place where the defective column is situated and the place where the redundancy column which is going to replace it is situated. This correlation results from the simultaneous selection by AP of a group of amplifiers and of a group of addresses of defective columns connected to these amplifiers.

Abstract: Appareil et procédés associés pour un débitmètre de masse de Coriolis (5) insensible au bruit, et plus particulièrement un débitmètre qui n'est pas affecté par le bruit de fréquences différentes d'une fréquence fondamentale à laquelle le tube ou les tubes d'écoulement (130, 130') vibrent dans le débitmètre. D'une manière spécifique, le débitmètre (5) est fondé sur la mesure du débit de masse en déterminant la différence de phase se produisant entre les composantes réelles et imaginaires de la transformée de Fourier discrète (DFT) des formes d'ondes des capteurs de vitesse de gauche et de droite évaluées à la fréquence fondamentale à laquelle les tubes d'écoulement vibrent. La fréquence fondamentale est localisée, lors d'une opération d'initialisation, en établissant un spectre de puissance déterminé en utilisant la DFT, l'un des signaux des capteurs et en sélectionnant la fréquence à laquelle l'intensité du spectre de puissance atteint une valeur maximale. De plus, la fréquence à laquelle les deux signaux de capteur de vitesse sont échantillonnés est réajustée en réponse à tout changement de phase de l'un des signaux de capteur de vitesse, transformé en utilisant la DFT, de manière à s'assurer que la fréquence d'échantillonnage reste toujours sensiblement égale à un multiple d'un nombre entier prédéfini de la fréquence fondamentale. En outre, en utilisant la valeur numérique de tout changement de phase, le débitmètre produit également une indication de densité qui est également insensible au bruit.

Abstract: An RF power device including a DMOS field effect transistor has increased efficiency and reduced distortion. A capacitor is connected between the gate and source input of the transistor which swamps non-linear variations of the parasitic capacitance (C GD ) between the gate and drain, thereby offsetting the Miller effect of the feedback provided by the MOS transistor parasitic capacitance. The capacitor, the Ciss of the MOS transistor, and the inductance of input leads provide a device input resonant frequency between the input signal fundamental frequency and the first harmonic.

Abstract: Pixels within an image are labelled based on near neighbor attributes. The attributes may be attributes for a near neighbor link or for a near neighbor pixel to which the link leads. The near neighbor attribute data for a pixel may indicate attributes for plural near neighbor links, and a link relationship criterion may be applied to determine whether the links are related in a manner that meets the criterion. For example, a pixel may be labelled only if its near neighbor links include a pair with relative orientation difference of approximately 180°, both of which have been previously labelled or are links to a boundary; this criterion is useful in labelling a partially-bounded region. A distance-independent connected component labelling criterion may be applied during parallel labelling of pixels for rapid connected component labelling. Labelling based on a near neighbor labelling criterion may be iterated until a component or region is completely labelled.
