Abstract: Various attachments (different dozer blade arrangements, a gantry crane, large auger) are designed for use with multiple identical powered mobile modules including a main support frame housing an internal combustion engine as a prime mover and being supported on either powered tracks or wheels. The modules can be either equipped with a cab and manned or used without a cab and controlled remotely. One or more of the mobile modules may be equipped with a GPS unit to aid in positioning the associated attachment.

Abstract: A seating apparatus includes a torso rest and a semi-seat support or partial support for the seat of the operator of a work vehicle. The torso rest provides support for the torso when the operator leans against the torso rest in a semi standing position and is contoured to act as a backrest in a first operator position and as a front rest in a operator second position. The semi-seat support acts as a partial seat support only in the first operator position. The seating apparatus may also include an additional stowable seat support, armrests, a height adjustment assist mechanism and/or a control console.

Abstract: A door hinge having a first hinge member is attachable to a door frame, and has a cup-like recess in which a portion of a second hinge member, attachable to a door associated with the door frame, is received when the first and second hinge members are in a closed position. The second hinge member can include an arm hinged to the second hinge member at a location inside the cup-like recess. When the door is opened, the arm rotates about the hinge, lifting the second hinge member up out of the recess away from the first hinge member. Maximum travel of the second hinge member is limited by impingement of the arm against an adjacent side of the cup-like recess. A range of adjustment of travel can be provided by an adjustment member cooperating between the arm and the adjacent side of the cup-like recess. The adjustment member can be a set screw disposed in a threaded opening through the arm, allowing the set screw to contact the adjacent side of the cup-like recess.

Abstract: A method and apparatus for enabling a listening daemon in a client/server system to execute a specified task on behalf of a user. Upon receiving a user request, the listening daemon sets an environment variable in accordance with the user identity specified in the request and issues a system call to the operating system kernel to spawn the user task specified in the request. In response to the system call, the operating system kernel creates a new address space for the specified user task and creates a security environment for the user task in accordance with the environment variable before starting the user task in the new address space.
