Abstract: A conveyor belt includes at least one rip detection sensor having at least two cords, each cord formed in an endless loop and arranged in a signal inverting configuration, and at least one cross connector connecting the at least two cords so as to arrange the at least two cords in a parallel configuration. The sensor provides a redundancy feature such that should one cord break, the remaining cord allows the sensor to continue operation. The parallel configuration of the cords reduces overall resistance of the sensor and extends the sensor life as the conveyor belt wears.

Abstract: This invention is a synchronization abstraction layer (SAL) providing a uniform interface to frameworks operating on sequenced flow data. It allows content developers to design and build interactive content that will operate interchangeably in different multimedia frameworks (e.g., Apple Computer, Inc.'s QuickTime™, Microsoft Corporation's NetShow™, RealNetworks, Inc.'s RealPlayer™, Sun Microsystems, Inc.'s Java™ Media Framework) and on different hardware platforms (e.g., desktop PC, Macintosh™, Television set-top boxes such as those from General Instrument Corporation and Scientific Atlanta Inc., Inc., Internet appliances such as AOL™-TV, and other appliances, e.g., a kitchen Internet radio). The uniform interface is independent of the particular framework and the platform on which the SAL is implemented, so that a single instance of content, whether created in Java™, JavaScript, VBscript, HTML, XML, or some other language, can run appropriately on different hardware, e.g.

First and second computers at different geographic locations acquire the data via an internet. Thus, data relating to the operating conditions of the conveyor belt can be remotely consolidated and monitored by computers at different global locations.

Abstract: A device suitable for wireless communication with a network entity. The device comprises a functional unit configured to monitor an operational state of the device and, in response to detecting that the device is in a de-powered operational state, to inform the network entity of an ability of the device to wirelessly communicate with the network entity during a future time interval while the device remains in a de-powered operational state. A second functional unit capable of wireless communication with the network entity may also be provided and may be selectably powered from either a main power source or an alternate power source such that the second functional unit is powered from the alternate power source during the future time interval and becomes unpowered from the alternate power source after the future time interval. Thus, de-powered devices can be located and communicated with more easily.

Abstract: A digital processor for use in a conveyor belt rip detector, which provides excitation signals at a selected frequency to inverted and noninverted sensor loops on a conveyor belt and then, detects corresponding received signals from the sensor loops. The digital processor then performs FFTs on the corresponding received signals to provide respective received signal frequency spectrums. Next magnitude and phase values of the selected frequency in the respective received signal frequency spectrums are used to determine a qualitative state of the sensor loops. The selected frequency has a lowest detected ambient noise level, and the magnitude value is a normalized magnitude value.

Abstract: At least one network device that moves storage blocks based upon a session layer or higher protocol set is employed to facilitate communication between at least one host and at least one target storage device. The at least one network device may include a server and a switch. Transactions related to data storage access are expressed in a non-network protocol and transmitted via a network protocol data unit across at least a portion of the network by employing encapsulation. An adapter card associated with the data storage unit is employed to extract the non-network protocol transaction. Multiple, mirrored data storage units that are separated by relatively large physical distance may be employed to reduce the likelihood of catastrophic data loss due to an event such as a fire. Further, READ transactions may be facilitated by preloading data storage units with READ metadata for subsequent transmission to a client device to enable expedited access to data stored on the data storage units.

Abstract: A system and method are provided for regulating incoming traffic to a web site to prevent overload conditions from occurring. The system comprises a capacity determination unit for determining if a web site has additional capacity and a notification unit for notifying customers if no capacity is available. A scheduling processor provides a customer with scheduling options. When the web site has sufficient capacity, a redirect unit redirects the customer to the web site.

Abstract: A method and apparatus for providing network based load balancing of medical image data among two or more image archive systems is disclosed. A network element is employed to interface to a network carrying medical image data that may include tasks to be performed on the data. A network service associated with the network element monitors the current load or the available capacity of each of the image archive systems. When a task is received the network service determines the level of complexity of the task and compares the level of complexity to the current load or available capacity of each of the image archive systems. The network service selects the one of the image archive systems to perform the task that has the lowest current load or highest available capacity relative to the level of complexity of the received task.

Abstract: A technique for enabling a shared storage provider (SSP) to provide shared data storage to a plurality of customers while providing greater privacy and security of each customer's data by implementing a virtual private (VP) addressing scheme is disclosed. The technique also allows a storage networking service carrier to provide connectivity between a plurality of customer storage networking sites, keeping each customer separate from each other. In one embodiment, the technique is realized by network architecture and a scheme to separate and virtualize storage traffic and stored data on a shared infrastructure.

Abstract: A single use syringe (10) has an outer barrel (11) and an inner barrel (12) slidable within the outer barrel. The two barrels are initially latched together to prevent relative movement therebetween whereby the syringe is in a useable condition. A needle (16) is in fluid communication with the inner barrel and projects initially from a first end of the outer barrel. A plunger (21) in the inner barrel is connected to a plunger actuating rod (22) which extends out the other end of the outer barrel. On first depression of the plunger actuating rod a limit catch (23) prevents full depression thereof but allows sufficient depression to draw fluid into the inner barrel. On the second depression the fluid is ejected and the plunger actuating rod and plunger are allowed full travel whereby latching between the two barrels is disengaged. It is not possible to re-latch the barrels together in the useable condition and therefore further use of the syringe is not possible.

Abstract: Distributed security for industrial networks is achieved through the implementation of Security Policy Implementation Points (SPIPs) on the network to apply security policy in a distributed fashion to prevent network users from taking action in particular areas of the network. The SPIP integrates with network services to perform authentication and authorization services on behalf of particular factory machines, groups of factory machines, and other industrial network resources. The SPIP also maintains a local access policy to enable emergency access to the factory machines as well as enable local access to attendant programmable logic controllers. The SPIP also includes audit functionality to enable the SPIP to record local accesses and network accesses to maintain a log of users and network devices that have interfaced with the SPIP. The SPIP may also support VPNs, encryption, compression, and numerous other functions to engage in communications on the network.

Abstract: The generation and extensive synthesis (“amplification”) of a cDNA sequence of interest is attained through a linked series of multi-cycle primer extension reactions (RT-LLA). The primers used in each of the primer extension reactions of the process contain non-replicable and, in some cases non-replicable and cleavable, elements that halt nucleic acid synthesis and thereby prevent the synthesized molecules from serving as templates in subsequent cycles. Synthesized molecules accumulate during primer extension in a mathematically linear fashion, thereby rendering the process relatively insensitive to contaminating nucleic acids. Multiple primer sets are employed, and simultaneously included in the reaction mixture, thereby ensuring the accumulation of a large number of copies of the cDNA sequence of interest.
