Abstract: A method comprises storing pixel data in a frame buffer, retrieving the pixel data from the frame buffer and processing at least one pixel value of the pixel data to generate an output pixel bit stream. The method further comprises storing pixel values in a first update buffer. The pixel values are derived from the output pixel bit stream. The method also comprises providing the pixel values from the first update buffer across a network to a remote graphics system.

Abstract: A lift truck cab having front, side, and rear faces, and a roof, mounting structure attached to the roof for suspending the cab from a mast of the lift truck in a manner that permits the front and side faces when installed on the truck to be hung in the manner of curtains without the necessity of direct fastening of lower portions of the front and side faces to the chassis/body of the truck. The cab construction affords generous operator space, high visibility, a convenient electrical raceway and ready access to truck control circuitry.

Abstract: An apparatus and a method are provided for performing network routing. The present invention comprises authentication logic, decision logic and routing logic. The authentication logic is configured to receive packets sent from a source agent to a tunnel endpoint and to determine whether or not the security association corresponds to the source agent that configured the tunnel. The decision logic makes a routing decision that is constrained based on the security association of an authenticated. The routing logic then selects a routing destination for the authenticated packet that is based at least partially on the routing decision made by the decision.

Abstract: A method of securely connecting a plurality of client computers to computer resources in a shared computer system by extending client network domains around computer resources in the shared computer system. The network domains of different clients remain isolated from one another in the shared computer system. The method includes associating each of the plurality of client computers with at least one virtual private network connection. The plurality of client computers are remotely connected to at least one virtual private network termination device in the shared computer system. The at least one virtual private network connection is established by the at least one virtual private network termination device. The at least one virtual private network connection is associated with a plurality of virtual local area networks. At least one of the computer resources in the shared computer system is associated with each of the plurality of virtual local area networks.

Abstract: A security-enhanced network storage device. Apparatus and methods disclosed which allow network-connected client systems or groups of such systems to access data storage devices over the network in a highly secure fashion. Systems not having the appropriate permission are excluded from access. Characteristics of such a network attached storage device include the following: (1) Clients can only access the data they have been given permission to access, based on a combination of access control lists and physical system interconnects. (2) Client data access permissions in representative embodiments are stored and managed on the security-enhanced network attached storage device and are not accessible by clients, thereby improving data security. (4) Client access permissions can be checked on a per-IP-packet basis, so that all data transfers can be validated before they occurs, thus also, improving data security.

Abstract: A system, particularly suited for after market applications, for enclosing an overhead guard with window and prehung door assemblies. The window and door assemblies are arranged with portions that overlie outer surfaces of the guard and portions engageable with inner surfaces of the guard to retain the respective assemblies in place on the guard. The retaining structure of each of the assemblies extends through original vision or ingress/egress openings in the guard so that installation is simplified and structural alteration of the guard is avoided.

Abstract: The present invention is generally directed to a system and method for communicating graphics across one or more computer networks. Broadly, the system comprises an input for receiving a video signal, a memory for storing discrete units of the video signal, and a network interface circuit coupled to both the compression circuit and the computer network, the network interface circuit configured to format and communicate the compressed video signal over the computer network to a remote computer. In a preferred embodiment, the system also includes a compression circuit for compressing a plurality of the discrete units into a compressed video signal. In accordance with another aspect of the invention, a method is provided that receives a video signal, converts the video signal into a format suitable for communication over a computer network, and communicates the converted video signal across the computer network to a remote computer.

Abstract: A set of panel assemblies for enclosing the overhead guard of a vehicle such as a skid steer comprising a windshield/door assembly and side window assemblies. The windshield/door assembly includes a door jamb that is clamped over the front corner posts of the overhead guard and a windshield/door unit hinged on the jamb. The windshield/door unit seals against a generally planar front face of the jamb. The side window assemblies comprise transparent rigid plastic sheets adapted to be attached to the side grille of the overhead guard in a simplified manner and without occupying excessive space in the clearance area between the overhead guard and operating elements such as the lift arms of a bucket.

Abstract: An overhead guard for a vehicle, in the form of a cab for a lift truck, that affords both protection and a high degree of overhead visibility with a relatively open grille work of steel bar and an impact-resistant glazing sheet. The glazing sheet is sandwiched between a rigid framework and a sheet metal panel having a large cutout for the overhead view. Gusset plates reinforce the corners of the framework and provide convenient mounting locations for an air circulating fan. Threshold adaptor brackets are mounted in step pockets of the vehicle chassis to simplify the door structure while permitting the cab to be effectively sealed from the environment when the doors are closed.

Abstract: An address illumination system includes a lamp and a lamp housing arrangement mounted to a base structure having display symbols thereon. The lamp housing directly illuminates the display symbols to provide improved visibility and aesthetic appeal. The lamp housing can be elongated and either spaced from the display symbols by support bars attached to the base or directly mounted to the base. The lamp housing is configured to angle the illumination from the lamp to increase visibility of the display symbols such as a house address during nighttime. The address illumination system also includes control features to provide a flashing lamp to signal emergency vehicles or the like as well as remote control operation, photocell operation and/or operation at predetermined intervals of time. The address illumination system can be mounted to a structure such as a building or mail box.
