Abstract: Data samples describing a plurality of micro-segments that compose a symbol to be recognized are received from a device such as an electronic pad. Preprocessors map the micro-segments into cells of a plurality of feature arrays with different resolutions. Preprocessors assign values to the cells based on the length of a micro-segment associated with the cell, and how well the features of the associated micro-segment correspond to the feature label of the cell. The cell values are used as inputs to comparators that compare the feature arrays with reference arrays. The results of comparisons involving lower resolution feature arrays and reference arrays, are used to limit the number of comparisons involving higher resolution feature arrays and reference arrays. The highest resolution comparison selects the reference array that identifies the symbol to be recognized.

Abstract: A purified protein kalinin is disclosed that provides adhesion between epidermal keratinocytes and the underlying dermis. Purified kalinin localizes to the anchoring filaments of basement membranes of human subepithelial skin, trachea, esophagus, cornea and amnion when exposed to monoclonal antibody BM165. The protein has a molecular weight of approximately 400-440kDa and separates on Western blots into fragments of 165kDa, 155kDa, 130kDa and 105kDa when its disulfide bonds are reduced. The epitope of BM 165 is identified on the 165kDa fragment when the blots are probed with BM165. The protein has a rotary shadow image which reveals an asymmetric 170nm long rod having two globules at a first end and a single globule at a second end of the rod. A method is also disclosed for improving adhesion of transplanted keratinocytes to an underlying sub-strate, such as the human dermis, by optimizing the production of kalinin from cultured keratinocytes, or providing an exogenous source of kalinin between the keratinocytes and substrate.

Abstract: On obtient des produits à base de protéines de haute qualité à partir du lactosérum en soumettant celui-ci à une filtration à courant transversal dans un microfiltre. Le lactosérum et le produit de rétention circulent dans un circuit placé d'un côté de la zone membranaire de ce microfiltre alors que la partie du lactosérum qui a franchi la membrane par perméation circule dans un deuxième circuit placé de l'autre côté de cette membrane de façon que la baisse de pression reste constante sur l'ensemble de la zone membranaire et inférieure à 0,8 bar. On obtient ainsi un fractionnement des protéines du lactosérum faisant que les protéines et graisses de lactosérum dénaturées sont retenues dans le produit de rétention alors que les protéines de lactosérum non dénaturées franchissent la membrane et se retrouvent dans le perméat. On obtient, après un traitement final, un produit à base de protéines de lactosérum qui est riche en alpha-lactolbumine et en beta-lactoglobuline et présente une faible teneur en matières grasses.

Abstract: A liquid recording apparatus ejects droplets of liquid onto a recording medium. The apparatus has multiple liquid emitters whose emissions are activated by multiple power pulses. The power pulses are controlled to maximize the number of emitters which can be simultaneously energized while keeping the instantaneous power usage within prescribed boundaries. The multiple emitters are organized into banks of emitters whose numbers are small enough that all emitters within a bank can receive a correct level of power simultaneously without exceeding capacity of a shared power source. A circuit interleaves the power pulses to the emitters so that no bank of emitters are receiving power at the same instant of time. In this fashion, the recording apparatus can achieve maximum recording speed while employing the smallest capacity power source which is practicable.
