Abstract: A system and method is provided for preventing a dropout of an LED current. In one embodiment of the present invention, the system includes a voltage source, a first circuit, a second circuit, a controller, and at least one LED. The first circuit receives a reference voltage from the voltage source, receives set-point current data from the controller, and uses the reference voltage and the set-point current data to produce a threshold voltage. The threshold voltage is then provided to the second circuit, where it is converted into an output current, which is drawn through the LED. The second circuit then compares the threshold voltage to an output voltage corresponding to the output current, and provides an output to the controller. The controller then uses the output to determine whether a dropout has occurred. If a dropout has occurred, then second set-point current data is provided to the first circuit.

Abstract: The production of a diutan polysaccharide exhibiting increased viscosity properties as compared with previously produced polysaccharide of the same type of repeating units. Such an improved diutan polysaccharide is produced through the generation of a derivative of Sphingomonas sp. ATCC 53159 that harbors a multicopy broad host-range plasmid into which genes for biosynthesis of diutan polysaccharide have been cloned. The inventive methods of production of such an improved diutan polysaccharide, as well as the novel cloned genes required to produce the improved diutan within such a method, are also encompassed within this invention. Additionally, the novel engineered Sphingomonas strain including the needed DNA sequence is encompassed within this invention.

In such a manner, a method of not just increased production of the target diutan polysaccharide, but also production of a diutan polysaccharide of improved physical properties (of the aforementioned higher viscosity) thereof is provided. Such a diutan polysaccharide has proven particularly useful as a possible viscosifier in oilfield applications and within cement materials.

Abstract: The present disclosure provides a method of assigning media access control (MAC) addresses to image paths for a printing system. The method comprises: initializing a MAC address to each image path board in the printing system wherein the printing system includes at least two print engines each having an image path board; modifying a card cage enclosure to include a bit selector for each image path board; and, creating a unique IP address for each MAC address including generating a unique octet for each MAC address. A slot ID is used for the generating of the unique octet for each MAC address having a standard base value.

Abstract: A method supplies or creates a generic electronic index for a hardcopy printed item. The generic electronic index is based on the text within the hardcopy printed item. From this generic electronic index, the method creates a plurality of custom electronic indices from the generic electronic index. Such custom electronic indices can be based on user input and/or user feedback or can be created by marketing agencies, educational institutions, etc. Each of the custom electronic indices is a variant of the generic electronic index, and each of the custom electronic indices is adapted to a different target audience.

Abstract: Sphingomonas strains have extracellular polysaccharide (e.g., gellan, diutan) that is firmly attached to the cell surface. This attachment may limit polysaccharide production by impairing uptake of nutrients into the cell or due to limited sites for polysaccharide biosynthesis on the cell surface. Two genes for polysaccharide biosynthesis, designated gelM and gelN in gellan-producing strains and dpsM and dpsN in diutan-producing strains, have been inactivated by deletion mutations and shown to produce polysaccharide that is not firmly attached to the cell surface, i.e., slime form. Another gene for polysaccharide biosynthesis, designated gelI in gellan producing strains, was inactivated by insertion mutation and also shown to produce the slime phenotype. The homologous gene dpsi in the diutan producing strain should also be involved in the attachment of the polysaccharide to the cell surface.

Abstract: Mutational inactivation of proteins involved in para-cresol production in certain milk products results in improved taste and odor. The undesirable para-cresol forms over time as a result of enzymes produced by the bacterium that produces gellan gum. Since the gellan is typically used in a relatively unpurified form, the enzymes are added to the milk along with the gellan. Inactivation of the enzymes is a genetic means of eliminating the enzymes without requiring any additional purification or processing.

Abstract: An inflatable game incorporating a flexible, inflated structure filled with gas, suitable for users to jump and bounce thereupon and a suspended structure that permits users to be suspended above the inflatable structure. The suspended structure may be a zip line, a bridge, or the like. The suspended structure allows users to move from one elevated position on the inflatable structure to another elevated position. The inflatable structures used in conjunction with suspended features provide an added variety of activities to the user. For example, users can hang in midair, drop onto the inflatable structure from elevated heights, engage in competitive activities.

Abstract: A method and system for the determination of toner usage in proportion to image-feature density, with independent estimation of each color toner module consumption. The system accurately accounts for image-wise color interactions due to color occlusion that may effect the actual amount of toner used by multiple color modules. The method includes a toner replenishment flow control process that responds to the toner consumption/depletion in the developer material (e.g., toner and carrier) as determined by one or more estimation modules, and thus maintains a stable and constant toner/carrier concentration ratio.

Abstract: A dual acting master cylinder and reservoir assembly includes a pair of bayonets on the reservoir that are received within primary and secondary bosses of the master cylinder. The bayonets each include disks within their central openings wherein each disk has a control orifice for controlling the pressure rise in the associated primary and secondary braking circuits during the initial filling process of the master cylinder and reservoir assembly. Through means of the control orifices, the initial filling process of the braking system through the reservoir is effected while minimizing pressure differential establishment across the secondary piston.
