Abstract: The present invention discloses a method of separating or distinguishing carbohydrate substances. More particularly the method includes using fluorescent labeling reagents which have a positive charge when bound to a carbohydrate, involves separating the labeled carbohydrate substances, such as by performing electrophoresis to cause differential migration of different labeled carbohydrate substances, or by isoelectric focusing in a pH gradient. The fluorescent labeling reagents are preferably cyanine dyes.

Abstract: A disposable calibration device is used to calibrate a measurement system which transmits radiation or acoustic waves to a material or tissue in order to effect measurements. The disposable calibration device includes a structure with a window through which the radiation or acoustic waves can be transmitted, as well as a removable calibration target arranged on the window and capable of returning a portion of the radiation or acoustic waves for calibrating the measurement system. The removable calibration target can be peeled from a window to allow a measurement to be made on the material or tissue. Once a measurement is complete, the disposable calibration device can be discarded and a new calibration device can be inserted on the measuring system.

Abstract: The invention relates to a rubber composition containing relatively low levels of carbon black and/or silica reinforcement together with a particulate calcium carbonate and selected modifiers. The invention particularly relates to a tire having a component, particularly a tread, of such composition.

Abstract: A combined infection shield and calibration or reference target for use with a measuring instrument includes a removable calibration/reference layer. The removable calibration/reference layer has predetermined optical characteristics that can be utilized to calibrate or reference the instrument. When the calibration/reference layer is removed from the remaining portions of the device, the portion of the calibration/reference layer having the predetermined optical characteristics is irrevocably altered such that the calibration/reference layer cannot be reused. The combined infection shield and target may be attached to a shield holder, which in turn is attached to an instrument. Alternatively, the infection shield and target may be attached directly to an instrument. The target may include a calibration/reference layer having a reduced strength portion which causes the target to tear or separate in a predetermined manner.

Abstract: A method and system for dynamically manipulating values associated with graphical elements displayed within a graphic interface of a data-processing system. Initially a pointer element associated with a pointing device is displayed within the graphic interface, such that the pointer element is capable of movement in multiple directions in response to movement of the pointing device. A trackslide element and a moveable slider are displayed within the graphic interface. The moveable slider permits users to dynamically decrease or increase values associated with the trackslide element, such that the moveable slider is constrained to move only in a first direction along the trackslide element. The pointer element is then graphically attached to the moveable slider.

The compounds can be used as fluorescent dyes for labelling biomolecules.

Abstract: Novel squarate dyes are described, and adducts of these dyes with biologically significant chemical species such as nucleosides or nucleotides. The adducts have useful properties for fluorescent nucleic acid sequencing methods.

Abstract: Hoses are often reinforced with fabric to improve their performance characteristics, such as burst strength. For instance, radiator hose used in automotive applications is generally reinforced with continuous yarn. However, it is a labor-intensive process to manufacture such hoses which include fiber reinforcements. A substantial amount of material waste also generally occurs in the manufacture of such fiber-reinforced hose. By utilizing the technique of this invention, hose which has a high level of burst strength can be manufactured without including continuous yarn reinforcement.

Abstract: A system and method for calibrating a measurement instrument prior to making a measurement on a material or tissue includes utilizing a removable calibration device to calibrate the instrument, then removing a target portion of the calibration device so that a measurement may be performed. The calibration device may include an index matching agent, such as a gel, that is to be interposed between the patient's skin and an output end of the measuring instrument. A method embodying the invention may include making a bilirubin concentration measurement on a skin of a patient by measuring the amplitude of light reflected from the patient's skin at first and second wavelengths indicative of a blood content of the patient's skin, and measuring the amplitude of reflected light at a third wavelength indicative of an uncorrected bilirubin concentration, then calculating a corrected bilirubin concentration based on the three measurements.

Abstract: A fluid jet blood sampling system and method for obtaining a blood sample from a mammal, utilizes a fluid jet from a disposable jet nozzle to perforate at least the epidermis of the skin and to break at least one blood vessel, thereby allowing a quantity of blood to accumulate on the skin surface of the mammal. A cowling prevents contamination of the local environment with excess fluid, blood, etc. A drying unit may be provided to remove excess fluid, blood, etc. from the skin within the cowling. A sample of blood may be transferred to a test strip, or a collection unit may be used to collect and contain a blood sample from the mammal.

Abstract: A combined infection shield and calibration or reference target for use with a measuring instrument includes a removable calibration/reference layer. The removable calibration/reference layer has predetermined optical characteristics that can be utilized to calibrate or reference the instrument. The calibration/reference layer may have predetermined reflectance or scattering properties, a predetermined transmissivity to light, or it may have predetermined fluorescence properties. When the calibration/reference layer is removed from the remaining portions of the device, the portion of the calibration/reference layer having the predetermined optical characteristics is irrevocably altered such that the calibration/reference layer cannot be reused. The combined infection shield and target may be attached to a shield holder, which in turn is attached to an instrument. Alternatively, the infection shield and target may be attached directly to an instrument.
