Abstract: The present disclosure provides a centralised virtual and augmented reality activity system comprising a plurality of co-located virtual reality suites, each fully equipped with virtual reality accessories and set in an environment that is safe and spacious. The user devices of each suite are managed by a central server, also in the same location, which allows for interactions both between users of the different suites and facilitates normal interaction between the user devices and the internet.

Abstract: A system for simulating an event includes a memory system, a parity generator/validator, and a fault injector. The fault injector is configured to inject bits at an address in the memory system when the parity generator/validator is in an disabled state. A method of injecting a fault is also disclosed.

Abstract: A management capability is provided for a virtual computing platform. In one example, this platform allows interconnected physical resources such as processors, memory, network interfaces and storage interfaces to be abstracted and mapped to virtual resources (e.g., virtual mainframes, virtual partitions). Virtual resources contained in a virtual partition can be assembled into virtual servers that execute a guest operating system (e.g., Linux). In one example, the abstraction is unique in that any resource is available to any virtual server regardless of the physical boundaries that separate the resources. For example, any number of physical processors or any amount of physical memory can be used by a virtual server even if these resources span different nodes. A virtual computing platform is provided that allows for the creation, deletion, modification, control (e.g., start, stop, suspend, resume) and status (i.e.

Abstract: A virtualized storage adapter architecture and method is provided wherein lower level details of the storage adapter architecture are isolated from an operating system and its applications that execute on a virtualization architecture. This isolation may be performed, for example, by providing a virtual storage adapter that is backed by one or more physical storage adapters. The virtual storage adapter may be referenced by a globally unique identifier. For example, the virtual storage adapter may be referenced by a World Wide Node Name (WWNN). In another example, changes may be made to the underlying physical storage configuration without the need for changes in the virtual storage adapter or its interface to an operating system or its applications.

Abstract: A printing system in which it is determined whether the print heads of a printer are effectively aligned and, depending on whether or not the print heads are effectively aligned, one of multiple different printing schemes is selected for controlling printing of a print job, wherein the selected printing scheme for the case when the print heads are not effectively aligned includes controlling printing by directing the printer to use only one selected print head.

Abstract: A printer driver executable in a computer connectable to a driven printer. In response to initiation of a print job, the print driver obtains current status of the printer. Based on the status of the printer, the print driver modifies operational parameters of the printer prior to commencement of the print job, so that the operational parameters are different from default ones of such parameters. In addition, the print driver modifies its own operational sequence based on the printer status, so that the operational sequence of the printer is different from a default sequence without such status information.

Abstract: Printing on a recording medium by lateral scans of a print head in accordance with print data. Content of print data is determined. Then, the print data is printed either with a first lateral scan process using a critical zone at edges in a lateral scan of the print head for printing, or with a second lateral scan process that does not use the critical zone for printing. The first or second lateral scan process is selected based on the print data. Preferably, the critical zone is sized in correspondence with ramp up non-uniformities of a print carriage on which the print head is mounted, so as to accommodate a distance between a point where print degradation due to speed non-uniformities are noticeable to a point where print degradation due to speed non-uniformities are no longer noticeable. The second lateral scan process preferably is a process in which a predetermined margin is inserted into the first lateral scan process.

Abstract: A system to produce print data corresponding to a multi-level value of a pixel includes a first determining step to determine a first amount of low-penetration black ink corresponding to the multi-level value, a second determining step to determine a second amount of high-penetration black ink corresponding to the multi-level value and a printing step to print the pixel using the first amount of low-penetration black ink corresponding to the multi-level value and the second amount of high-penetration black ink corresponding to the multi-level value.

Abstract: Improved techniques for measuring misalignment between multiple print heads, or between forward and reverse printing for the same print head. Adverse effects of ink bleeding, paper cockling and other ink ejection effects are reduced by superimposingly printed alignment patterns in which less than all pixels of printed portions of the patterns are filled in. Carriage ringing and overshoot effects are reduced by printing the alignment patterns in multiple passes, and preferably with an offset in carriage starting location for each pass. Improved detection of darkest density regions of the superimposingly printed alignment pattern is obtained through detections based on differences between densities rather than absolute values of measured densities.

Abstract: A printing system to print bands of print data in a forward direction and in a backward direction. The system includes a step to print print data other than black print data included in the bands of print data using bidirectional printing and a step to print black print data included in the bands of print data using unidirectional printing.

Abstract: A gas flow rate measurement apparatus for obtaining a normalized flow rate of a gas having at least one liquid component. The gas travels from an upstream position and in a downstream direction.

Abstract: A system and method for turning up a web of paper moving in a tensioned condition across the surface of a rotating reel at the winder of a paper making machine from a first drum to a second drum utilizes a conduit for receiving air from a pressurized air source and having a discharge end through which pressurized air received from the source exits the conduit in an air stream. A stand supports the conduit adjacent the reel for movement between an operative position at which the discharge end is positioned adjacent an edge of the web and a non-operative, out-of-the-way position situated to one side of the reel. A cylinder assembly is connected between the conduit and the stand for moving the conduit between its operative and non-operative positions, and a solenoid valve is connected in-line with the conduit permitting a sudden stream of air to exit the discharge end upon actuation of the valve.
