  • Patent number: 9662746
    Abstract: A load-bearing member for a linkage assembly of an implement system includes a body and a joint assembly. The body includes a pair of sidewalls, a top portion, and a bottom portion. The top and bottom portions extend between the sidewalls and are connected to an inner surface of each of the sidewalls. The body is substantially free of structural weldments disposed within an interior cavity of the body. The joint assembly includes a cylindrical tube and a reinforcement plate. The cylindrical tube extends between and is connected to the sidewalls. The reinforcement plate is connected to an outer surface of one of the sidewalls. The reinforcement plate includes a central portion defining a tube opening and is in circumscribing relationship with the cylindrical tube such that it is disposed within the tube opening.

  • Patent number: 9650756
    Abstract: A stick for a linkage assembly of an implement system includes a stick body and a stick joint assembly. The stick body defines a neutral axis and includes a pair of sidewalls in lateral spaced relationship to each other, a top portion extending between the pair of sidewalls, and a bottom portion extending between the pair of sidewalls, which define an interior cavity. The stick joint assembly includes a stick joint tube and a stick joint reinforcement plate. The stick joint tube extends between and is connected to the sidewalls. The stick joint reinforcement plate is connected to one of the pair of sidewalls and includes a pair of arms extending from a central portion. The ends of the first and second arms of are disposed along the neutral axis of the stick body.

  • Patent number: 9376783
    Abstract: A boom for a linkage assembly of an implement system includes a boom body and a fork reinforcement plate. The boom body includes a pair of sidewalls, a top portion, and a bottom portion. The top portion and the bottom portion extend between the pair of sidewalls. The top portion and the bottom portion define a boom nose at a distal body end. The sidewalls each include a fork portion disposed at the distal body end and extending in outward relationship to the boom nose. Each fork portion defines therein a stick mounting opening. The fork reinforcement plate is connected to the inner surface of one of the pair of sidewalls at the fork portion. A proximal plate end of the fork reinforcement plate is in abutting relationship with the boom nose.

  • Publication number: 20090226186
    Abstract: The present invention provides a method for biasing/controlling an optical demodulator suitable for use in an optical phase-shift-keying (PSK) system, such as an optical differential-phase-shift-keying (DPSK) system or an optical differential-quadrature-phase-shift-keying (DQPSK) system, the method including: receiving a signal from an optical demodulator/balanced receiver pair; full-wave rectifying the signal; passing the full-wave rectified signal through a low-pass filter; monitoring the full-wave rectified signal received from the optical demodulator/balanced receiver pair and passed through the low-pass filter; and providing related feedback to the optical demodulator. Preferably, the signal includes a radio frequency (RF) signal. Full-wave rectifying the signal includes full-wave rectifying the signal using a full-wave rectifying circuit. Optionally, the low-pass filter includes about a 1 GHz bandwidth (BW) low-pass filter.

  • Patent number: 6647079
    Abstract: In accordance with an aspect of the present invention, a circuit is provided which is configured to recover clock and data streams from an incoming signal. The circuit comprises a multiplexer having first and second inputs, and an output. The first input is configured to receive the incoming signal, and the second input is configured to receive a reference clock signal, while the output selectively supplies one of the incoming and reference clock signals. A toggling circuit, such as a flip-flop, and a frequency multiplier circuit are further provided which are coupled to the multiplexer output. A filter circuit is coupled to the frequency multiplier circuit, and the output of the filter circuit is coupled to a second input of the toggling circuit. Moreover, the output of the filtering circuit corresponds to the recovered clock stream, and an output of the toggling circuit corresponds to the recovered data stream.

  • Publication number: 20030192836
    Abstract: An attic mounted storage compartment, comprising a housing having an opening at a lower portion thereof. The compartment is adapted to be mounted between two neighboring ceiling joists, so that storage items may be raised therethrough for positioning within the housing. The compartment includes a lift apparatus, which is used to lift storage items into the housing. The lift apparatus may be manually operated or motor driven. Two preferred types of storage items useable with the compartment are bicycles and storage boxes sized to conform to the general shape and size of the housing.
