  • Publication number: 20240083725
    Abstract: A material handling vehicle is provided, which includes a counterweight assembly. The counterweight assembly includes a counterweight, a positioning member, and a position adjuster. The position adjuster is configured to advance or retreat the positioning member to adjust a distance the positioning member emerges from the counterweight thereby adjusting a position of the counterweight relative to a frame of the material handling vehicle.

  • Patent number: 11820635
    Abstract: A material handling vehicle is provided, which includes a frame having an aperture directed through the frame and configured to receive a battery pack, and a counterweight assembly. The counterweight assembly includes a counterweight having a first opening, and an opposite second opening, a first positioning rod having a first end, and an opposite second end. The first end is directed through the first opening. A first nut is threadingly engaged with the second end of the first positioning rod. The first nut is rotated in a first direction to advance the first end of the first positioning rod farther through the first opening to contact the frame, thereby adjusting the position of the counterweight relative to the frame.

  • Patent number: 8832656
    Abstract: Systems and methods for providing symbolic information about fields, methods, and/or classes for a target device. A system and method may be used where the runtime processing is split between a host system and a target system. At the target device a test program uses a symbol not defined on the target device. A query is sent from the target device to a symbolic information source. The symbolic information source then provides the target device with information about the undefined symbol. The target device uses the information from the symbolic information source to complete the test program.

  • Publication number: 20100102609
    Abstract: A lift truck includes a seat assembly having a first frame and a seat bottom pivotably mounted to the frame for pivotable movement between a standing operating position and a sitting operating position. The seat bottom has an upper facing surface for supporting an operator sitting on the seat bottom when the seat bottom is in the sitting operator position and a lower surface facing outwardly when the seat bottom is in the standing operator position for supporting an operator leaning against the seat bottom.

  • Patent number: 5329604
    Abstract: An optoelectronic system including an optoelectronic assembly for receiving and/or transmitting optical data signals, optic means for being optically coupled to the optoelectronic assembly, and an optical fiber coupling device for coupling the optic means and at least one of the optoelectronic devices which form part of the assembly. The coupling device includes a housing for being positioned adjacent the assembly relative to the optoelectronic device and, significantly, latching means movably positioned within the housing for initially engaging the optoelectronic device and thereafter for engaging the incoming optic means (e.g., optical fiber connector) when the optic means is positioned within the coupling device's housing. Keying and shutter means are also provided as part of the coupling device.

  • Patent number: 5315679
    Abstract: An optical fiber duplex connector assembly wherein two individual optical fiber connectors are positioned and retained within a common housing, such that relative freedom of movement between the two connectors within the common housing facilitates positioning of the retained two connectors within a suitable receiving common housing (e.g., shroud). Such movement accomodates for manufacturing tolerances within the housing and/or connectors while still assuring successful insertion. A housing, having two chambers (one for each connector) and a cover assures the defined movable connector positioning while also providing effective retention. A boot may be attached to the housing to accomodate for severe bends and turns of the optical fiber cable, without loss of attenuation.

  • Patent number: 5228863
    Abstract: A connection device is provided for electrically coupling a primary circuit surface to a companion circuit surface via a flexible circuit strip for interconnecting the circuit surfaces. The connection device includes a companion positioner which has a companion-coordinating side, and a primary positioner which is coupled to the companion-coordinating side and which includes a primary-coordinating side. The companion coordinating side is adapted to be positioned parallel to the companion circuit surface, and includes a set of companion-positioner registrants for precisely positioning the companion-positioner relative to the companion circuit surface and a section of the interfacing circuit surface. The primary-coordinating side is adapted to be positioned parallel to the primary circuit surface, and includes a set of primary-positioner registrants for precisely positioning said primary-positioner relative to the primary circuit surface and another section of the interfacing circuit surface.

  • Patent number: 5199892
    Abstract: A connector assembly for effectively coupling two pairs of connectors wherein one of the pairs is located on a first member, e.g., a chassis, and the second pair is located on a rigid second member, e.g., a slidable card/board structure, adapted for being positioned relative to the first member such that the one pair of connectors on the second member engage the pair on the first member. The receiving connectors are each adapted for movement in response to engagement by the engaging (partner) connectors to thus compensate for possible misalignment of the second connectors. The first of these receiving connectors is movable in two different manners of direction while the second is movable in at least three (and in one embodiment, four) different manners of direction. A component for an information handling system which uses such a connector assembly as part thereof is also provided.
