Abstract: A fuser assembly includes first and second fuser structures, drive apparatus and nip engagement and release apparatus. The nip engagement and release apparatus includes nip-loading structure, a bias spring for engaging the nip-loading structure, a nip release cam for engaging the bias spring, a swing arm assembly and nip release structure. The nip engagement and release apparatus is adapted to cause a fuser nip to release during a reverse operation except when performing a duplex operation.

Abstract: Laser beam scan line nonlinearity is compensated for by providing algorithms for generating linearity profiles which are used by a corresponding registration system in an electrophotographic device to determine the placement of Pels across a scan line.

Abstract: An industrial vehicle includes a battery that is shaped to expand or otherwise modify the space available within an operator's compartment. As a result, operator accommodations may be satisfied within the space requirements of the vehicle. The present invention further provides an industrial vehicle having an adjustable feature, such as a repositionable operator's seat and/or repositionable control element or operator control surface, and a shaped battery that enables or otherwise corresponds with the repositioning capability of the adjustable feature.

Abstract: Methods, systems and computer program products are provided for authenticating a message from a client using a first authentication protocol and a resource manager using a second authentication protocol different from the first authentication protocol by generating a second message from the message from the client. The second message may include information from the client which has been authenticated using the first authentication protocol. The second message is authenticated using the second authentication protocol and the authenticated second message is provided to the resource manager.

Abstract: Methods, systems, and computer program products for improving data transfer in complex computing environments. Internal routing enhancements are defined, which enable traffic of virtual servers to be processed more efficiently, thereby improving overall data transfer rates. Instead of performing routing operations in the Internet Protocol (“IP”) layer of a networking stack, a “mini-routing” table is created programmatically and is used to perform routing at the Data Link Control (“DLC”) layer. This technique avoids bottlenecks in the IP layer and speeds the data transfer process.

Abstract: An apparatus and method for searching a database of web site functional characteristics to identify web sites that are compatible with designated functions are provided. With the apparatus and method, a database of functional characteristics is compiled and a search interface is provided. The database may be compiled in an automatic, manual, or semiautomatic manner by, for example, retrieving web site content with various functions of a web browser disabled and analyzing the resultant output through the web browser. With the search interface, a user may enter designations of the functional characteristics that the user is either interested in having or not having in the resultant list of web sites. Based on the user's designation of functional characteristics, the search engine associated with the search interface searches the database of web sites and identifies the web site entries in the database that are compatible with the designated functional characteristics.

Abstract: A defect area management system for an optical storage medium including a management part producing a defect area management signal for real-time processing and transmitting the signal along with data to be written; and a write part executing a defect area management of the optical storage media, writing the data, applied by the defect area management signal from the management part, into the optical storage medium so that whenever a light pickup meets a defect block at the time of writing data requiring the real-time processing into the optical storage medium, it does not have to be moved to the spare area, thus reducing the time it takes to move the light pickup and removing shortcomings of the real-time processing.

Abstract: A resistive heater adapted for heating a fuser belt is provided. The heater comprises a substrate, a first resistive trace formed over the substrate, and a second resistive trace formed so as to at least partially overlap the first resistive trace.

Abstract: An asynchronous, peer-to-peer design is provided for synchronizing data on machines within a cluster using messaging. The data may be represented in memory as a document object model in secondary storage. Messaging may be handled by a messaging system with topic destinations. The design supports persistence management, locking, and transactions with rollback, and maintains a uniform state for the data across all nodes and secondary storage at all times. Furthermore, barring catastrophic failure of all machines in the cluster and secondary storage, there is no possibility of losing committed data.

Abstract: A pre-scan assembly for a laser scanning unit including printhead housing having a polygonal mirror and collimation assembly including a laser light source emitting a light beam along a light beam axis. The pre-scan assembly is located between the collimation assembly and the polygonal mirror and includes a pre-scan lens assembly including a carrier and a pre-scan lens supported in the carrier. The pre-scan assembly additionally includes a pre-scan mount for supporting the pre-scan lens assembly and defining angular alignment surfaces. The carrier includes outer side surfaces for engaging the angular alignment surfaces where engagement of the carrier side surfaces with the angular alignment surfaces aligns the pre-scan lens optical axis with the light beam axis in the scan direction.

Abstract: A collimation assembly for a multi-beamed laser scanner including a collimation housing mounted to a printhead housing of the laser scanner, and at least two adjustment brackets supported on the collimation housing and located adjacent to each other in a cross-scan direction. Each of the adjustment brackets includes a mount member and a laser light source is supported within each of the mount members, each of the light sources defining a respective light beam axis. At least two collimation lenses are also provided supported on the collimation housing and intersected by one of the light beam axes. Each of the adjustment brackets is movable relative to the collimation housing in a scan direction and in the cross-scan direction to locate each of the light beam axes at a predetermined position relative to a respective collimation lens.
