Abstract: A sample preparation procedure for mitochondrial (mt) DNA analysis is described. The present method for isolating mtDNA uses sedimentation techniques for separating erythrocytes from lymphocytes and platelets (crude buffy coat fraction), followed by DNA extraction from the crude buffy coat fraction by boiling in water. This approach improves the yield of mutant DNA, enhancing the sensitivity of subsequent mutation interrogation techniques and allowing for meaningful statistical treatment of the degree of heteroplasmy within the mitochondrial DNA.

Abstract: A foldable infant mattress system with a sleeping recess. A head mattress section is hingedly connected to a foot mattress section. Each mattress sections include an end wall and two laterally spaced apart sidewalls traversed to the end wall. The foldable infant mattress system is deployed in a flat position for sleeping and foldable into a closed position for carrying. In the flat position, the end wall and sidewalls of each mattress section together form the recess which contains an infant to a sleeping area. The walls are of sufficient thickness to allow for sound structural support and effective restraint of the infant. In the closed position, the mattress sections form a compact, easily carried assembly. A closing device such as a combination of straps and a snap is used which also forms a handle for carrying the mattress system. The mattress system is constructed of a foam material which is air permeable.

Abstract: A level shift circuit for a voltage input signal (S, SN) presenting at least a first and a second high-voltage levels, the circuit comprising two parallel branches, each formed by a current modulator and a signal converter. The current modulators are supplied with two signals in phase opposition to each other, and generate current signals whose value depends on the level of the respective input signal; and the signal converters convert the current signals into ground-related voltage signals. The signal converters together form a single-ended differential circuit, the output of which therefore presents a low-voltage digital signal which can be processed by normal digital circuits and is unaffected by noise or variations in supply voltage.

Abstract: A computer-based method and system for digital 3-dimensional imaging of an object which allows for viewing images of the object from arbitrary vantage points. The system, referred to as the Lumigraph system, collects a complete appearance of either a synthetic or real object (or a scene), stores a representation of the appearance, and uses the representation to render images of the object from any vantage point. The appearance of an object is a collection of light rays that emanate from the object in all directions. The system stores the representation of the appearance as a set of coefficients of a 4-dimensional function, referred to as the Lumigraph function. From the Lumigraph function with these coefficients, the Lumigraph system can generate 2-dimensional images of the object from any vantage point. The Lumigraph system generates an image by evaluating the Lumigraph function to identify the intensity values of light rays that would emanate from the object to form the image.

Abstract: A printhead having multiple print lines of conventional design and a printhead control system for using the multiple print lines in a variety of operations. In one embodiment, the printhead control system prints an image by superimposing the printing from multiple print lines. In another embodiment, the image is printed by alternating the energization of one print line so that each print line is used to print only 1/3 of the image lines. As a result, the print lines are allowed a relatively long time to cool, thus allowing the printhead to be operated at a faster speed. In another embodiment, the printing elements of each print line print with a different image density, and images printed by superimposing the printing elements in the print lines with a variety of combinations depending upon the desired magnitude of the image density.

Abstract: Light-colored phenolic-modified rosin esters, suitable for use as, for example, tackifiers in adhesive compositions, are prepared by reacting together rosin, a phenolic compound, formaldehyde or a reactive equivalent thereof, and a non-phenolic hydroxyl-containing organic compound in the presence of at least one lightening agent selected from phenol sulfide compounds, phosphorous acid, esters of phosphorous acid, and hypophosphite salts. The formaldehyde or reactive equivalent is present in an amount ranging from about 1.1 to about 3.5 equivalents of --CHO moieties per 1 equivalent of Ar--OH moiety of the phenolic compound, in order to obtain rosin esters having desirably low color, and adequately low molecular weight to effectively function as tackifiers.

Abstract: A process for the manufacturing of an integrated circuit having DMOS-technology power devices and non-volatile memory cells provides for forming respective laterally displaced isolated semiconductor regions, electrically insulated from each other and from a common semiconductor substrate, inside which the devices will be formed; forming conductive gate regions for the DMOS-technology power devices and for the memory cells over the respective isolated semiconductor regions. Inside the isolated semiconductor regions for the DMOS-technology power devices, channel regions extending under the insulated gate regions are formed. The channel regions are formed by an implantation of a dopant along directions tilted of a prescribed angle with respect to a direction orthogonal to a top surface of the integrated circuit, in a dose and with an energy such that the channel regions are formed directly after the implantation of the dopant without performing a thermal diffusion at a high temperature of the dopant.

Abstract: A sense circuit for reading EPROM and ROM type memory cells employs a circuit for generating an offsetting current which is exempt of error during transients and which thus permits to achieve a reduced access time. On the other hand, the sense circuit maintains the intrinsic advantages of a current-offset sensing architecture which is represented by a substantially unlimited operating voltage range toward the maximum value VCC.sub.max. The current generating circuit is driven by means of a supplementary row of cells which is decoded at every reading and which replicates, during transients, the behaviour of the row selected for the reading.
