Abstract: Devices, systems, and methods for explosion resistance include an analysis compartment isolated from a control compartment. A feed-through extends between the analysis compartment and the control compartment for extension of cabling therethrough, the feed-through hermetically sealed to block against flow of fluids between the analysis and control compartments.

Abstract: A fabric tube with two passages comprises a fabric tube sheet. A first fabric weld strip with right and left flanges extending laterally from a bottom edge of a weld fin is welded to a first surface extending the length of the fabric tube sheet at a distance D1 from the first edge thereof A second fabric weld strip is welded to an opposite second surface and extends the length of the fabric tube sheet between the first fabric weld strip and the second edge of the fabric tube sheet at a distance D2 from the second edge of the fabric tube sheet. The first edge of the fabric tube sheet is welded to the weld fin of the second fabric weld strip and the second edge of the fabric tube sheet is welded to the weld fin of the first fabric weld strip to form two passages.

Abstract: Example systems and methods are directed at maintaining and retrieving presence metadata. One example method includes receiving a request from a first client to edit a document file, and sending short-term check out metadata to the first client to begin an editing session. The method also includes writing the transition ID to a transition table stored in a cache, wherein the presence of another transition ID in the cache indicates that a document has switched from a single-client mode to a multi-client mode. An example system includes a processing unit operative to receive a document, the document including short-term check out metadata indicating an editing session has begun, ping a cache to determine if another transition ID is stored in the cache, and send a transition ID to a transition table stored in a cache to switch from a single-client mode to a multi-client mode.

Abstract: Examples are related to systems and methods for controlling access to document files on a document server. One example system includes document files stored on a document server, at least one of the document files referencing a file lock, and a document access processing module. The example document access processing module includes a file sharing processing module that determines a coauthoring status of a software application of a client computer requesting access to the document file, and a file lock processing module that stores one or more file locks and that controls the setting and resetting of file locks. The example document access processing module uses the coauthoring status of the software application and the file lock status of a document file to determine whether a software application is permitted to have write access to the document file.

Abstract: A hand paddle having a handle (hand grip) attached to the hand paddle blade allows the user to grip the hand paddle intuitively and ergonomically for use in whitewater with kayaks or boats. The paddle blade has a contoured hand well, which allows the handle to be positioned closer to the hand paddle blade substantially reducing the rotating force (torque) to the user's hands. The handle configuration allows user to quickly release the paddle in order to use hands in case of an emergency. The hand paddle further comprises a hand strap to prevent the paddle from rotating/pivoting in the user's hands. The hand paddle further comprises a lanyard, designed to break away under the weight of the user, securing the hand paddle to the user's wrist or forearm.

Abstract: A server computer includes a performance monitor module and a throttling logic module. The performance monitor module includes performance monitors that monitor system parameters of the server computer. The throttling logic module determines whether a system parameter monitored by a performance monitor exceeds a predetermined threshold. When a system parameter exceeds a predetermined threshold, the throttling logic module sets a throttling flag. The throttling logic module activates throttling at the server computer when at least one throttling flag is set for each of a predetermined number of time snapshots. The activation of throttling limits the processing of request messages received by the server computer.

Abstract: The invention provides, in one aspect, a digital data processing device includes a firewall device and a computer, both housed within the same enclosure and sharing a common path to the Internet (or other external network), yet, not sharing the same substantive processing logic. Thus, by way of example, the firewall device does not the computer's central processing unit (CPU) to execute firewall logic. The digital data processing device can be arranged to limit connectivity and/or functionality of the computer and/or firewall device, e.g., absent authentication. Thus, for example, the computer and firewall can be coupled to the common path—e.g., a modem, network interface card or other communications port supporting access via wired (e.g., wired ethernet and coaxial), wireless (e.g., satellite, telephony, 802.11x), and/or optical (e.g., fiber) means—such that that access by the computer to the Internet (or other external network) is mediated by the firewall device.

Abstract: A collision damage prevention system is disclosed which may be installed on many standard powered mobility vehicles for handicapped persons. The system includes an array of one or more sensors placed around the periphery of the powered mobility vehicle, a switch for each sensor, and a central control module which receives input from the switches, turns the vehicle off and/or applies braking power to prevent damage from a collision. The system then prompts the operator to acknowledge the collision and guides the operator into the appropriate direction to move the vehicle's controls in order to move away from the object collided with.

Abstract: An easily and conveniently attachable/detachable carrying handle and insert is disclosed which may be used with a portable computer. The insert has a retention member and is engageable by a latch mechanism of the computer housing and may be attached to the computer housing or substituted for a removeable device bay unit.
