  • Publication number: 20040064283
    Abstract: An instrument, in particular an electron microscope, has at least one user controllable operating parameter and at least one further operating parameter having a required value at least partially dependent on that of the user controllable parameter. A number of possible values of the further operating parameter are stored in a memory and each stored value corresponds to a respective possible value of the user controllable parameter. Selecting one of said stored possible values causes the instrument to be controlled accordingly. There is also provided a tuner for enabling the user to alter the selected value and updating apparatus for updating the memory accordingly, so that the adjusted value of the further operating parameter is subsequently selected from the memory if the same value of the user controllable parameter is then chosen again.

  • Publication number: 20040002071
    Abstract: The present invention provides new methods for the assessment of cancer risk in the general population. These methods utilize particular alleles of two or more genes, in combination, to identify individuals with increased or decreased risk of cancer. Exemplified is risk assessment for breast cancer in women. In addition, personal history measures such as age and race are used to further refine the analysis. Using such methods, it is possible to reallocate healthcare costs in cancer screening to patient subpopulations at increased cancer risk. It also permits identification of candidates for cancer prophylactic treatment.

  • Publication number: 20030230161
    Abstract: Abstract: A control housing body (10) containing a cavity (12) of sufficient size to allow entry and movement by a human thumb, and capable of housing a number of controls (14, 16). Body (10) is inserted under a covering grip (33) that is connected in line with a surface grip (32) of a rotating steering device (31). Dial control (14) is provided to set a scalar variable such as vehicular speed at a constant number. A thumb rest (13) and a control guard (17) inhibit the thumb from slipping downwards and unintentionally activating a contracting control (16) that can be actuated by the contracting movement of a human thumb. A sliding cover (40) can be alternately positioned over cavity (12) or inside retraction slot (46). A pivoting pin (22) and pivoting rotator (24) allow the control housing body to rotate around the axis between two pivot holes (26) and (28).

  • Publication number: 20030149526
    Abstract: The present invention generally relates to systems, methods and applications utilizing the convergence of any combination of the following three technologies: wireless positioning or localization technology, wireless communications technology and sensor technology. In particular, certain embodiments of the present invention relate to a remote device that includes a sensor for determining or measuring a desired parameter, a receiver for receiving position data from the Global Positioning System (GPS) satellite system, a processor for determining whether or not alert conditions are present and a wireless transceiver for transmitting the measured parameter data and the position data to a central station, such as an application service provider (ASP). The ASP, in turn, may communicate the measured data, position data and notification of any alerts to an end user via an alert device. The present invention also relates to various applications and systems utilizing the capabilities of such a device.

  • Patent number: 6520808
    Abstract: A connector with at least two pairs of contacts is provided, wherein crosstalk between first and third contacts, which are separated by a second contact, is reduced by a lateral extension of the third contact. The lateral extension includes a suppressing section extending parallel and adjacent to the first contact, and a pair of connecting sections that each connects one end of the suppressing section to the rest of the third contact. This allows at least some current passing along the third contact, to pass through the suppressing section and induce anti-crosstalk currents in the first contact to counter crosstalk. At least one connecting section has a lengthening portion that increases its length to create a phase shift. The suppressing section has a minimal width compared to its height. For a stamped sheet metal contact, the width is less than twice the height to reduce capacitive coupling while maintaining inductive coupling.

  • Patent number: 6458300
    Abstract: A process for pelletizing elastomeric anionically polymerized polymers which comprises subjecting the polymer to solid state extrusion in a single screw extruder with a length to diameter ratio of 10:1 or less wherein the barrel of the extruder has longitudinal grooves and transversally extending pins to increase mixing wherein the temperature in the extruder is sufficient to agglomerate or melt the polymer but be lower than the degradation temperature of the polymer and the speed of the extruder screw is from 30 to 100 rpm.

  • Publication number: 20020133856
    Abstract: A new cultivar of Lavendula angustifolia plant named ‘Walvera’ that is characterized by broad variegated foliage with gray-green centers and cream-white margins, a mounded, semi-open habit, and compact violet-blue flower spikes. In combination, these traits set it apart from all other existing varieties of Lavendula known to the inventors.

  • Patent number: 6243717
    Abstract: A system and method for implementing revision management of linked data entities and user dependent terminology. The present invention provides a novel method to implement revision management so that when a referenced data record is revised, no manual updating of any referencing data record is required to reflect the corresponding change. When defining a referencing data record, a user designates a choice of version of the referenced data record to be used with the referencing data record thereafter. Specifically, the user can either specify a particular version, in which case that particular version of the referenced data record will be used when the referencing data record is subsequently accessed, or the user can elect to use the “revision of record”, in which case the version of the referenced data record currently identified as the “revision of record” will be used.

  • Patent number: 6190857
    Abstract: Disclosed are diagnostic techniques for the detection of human disease states that affect gene expression in peripheral leukocytes. The invention relates particularly to probes and methods for evaluating the presence of RNA species that are differentially expressed in the peripheral blood of individuals with such a disease state compared to normal healthy individuals. The invention further relates to methods for detection of protein species that are differentially expressed in the peripheral blood of individuals with such a disease state compared to normal healthy individuals. Genetic probes, antibody probes and methods useful in monitoring the progression and diagnosis of two specific disease states, prostatic cancer and breast cancer, are described.

  • Patent number: 6187873
    Abstract: This invention is an improvement upon the current process for the production of block copolymers, especially hydrogenated block copolymers, of conjugated dienes and/or vinyl aromatic hydrocarbons which comprises anionically polymerizing the monomers in an inert hydrocarbon solvent in the presence of an alkali metal initiator whereby a polymer cement is produced and then contacting the cement with hydrogen under hydrogenation conditions in the presence of a hydrogenation catalyst. This invention and the improvement to the foregoing process comprises reducing the viscosity of the polymer cement by adding to it, preferably prior to hydrogenation (if the polymer is to be hydrogenated), from 2 to 50 % wt of a polar compound. The polar compound must be a poorer solvent for the block copolymer than is the inert hydrocarbon solvent. Preferred polar compounds include diethyl ether, tetrahydrofuran, diethoxyethane, monoglyme, diglyme, diethoxypropane, dioxane ortho-dimethoxybenzene, and the like.
