  • Patent number: 10179424
    Abstract: A diagnostic system for measuring acceleration of a piston of a reciprocating hammer is disclosed. The diagnostic system may include a magnet configured to induce, via electromagnetic induction and based on a movement of the piston, an electric current in a conductor. The diagnostic system may include a capacitor electrically coupled to the conductor and configured to store electric power based on the electric current induced by the magnet. The diagnostic system may include an accelerometer configured to measure an acceleration of the piston. The diagnostic system may include a communication device powered by the capacitor and configured to output a signal that identifies the acceleration measured by the accelerometer.

  • Patent number: 9303377
    Abstract: A hard link, which is connected to a moldboard of a machine, includes a first range of float capability and a second range of float capability. The second range of float capability may provide a greater float height to the moldboard than the first range of float capability. In another embodiment, a machine includes a moldboard, a jib arm operatively configured to raise and lower the moldboard, and a link attaching the jib arm to the moldboard. The link includes two discrete float capabilities.

  • Publication number: 20130206513
    Abstract: A linkage pin assembly is disclosed. The linkage pin assembly includes a grease fitting, a linkage pin, and a coupling. The grease fitting includes an outer shell. The outer shell encloses an internal cavity. The outer shell includes a thread blank having at a second end of the outer shell. The thread blank includes hardened lead threads. The hardened lead threads are induction hardened to at least RKW C 53. The linkage pin has an untapped hole. The coupling is between the grease fitting and the linkage pin. The coupling is formed when the hardened lead threads of the grease fitting create corresponding threads in the untapped hole of the linkage pin when the grease fitting is inserted into the linkage pin.

  • Patent number: 6243746
    Abstract: Software, method, and systems for representing devices on a computer network are described. In one embodiment the invention comprises a method which identifies devices on a computer network; creates topology objects configured to represent the devices; associates the topology objects with the identified devices; stores the associated topology objects in a database managed by a topology service. The embodiment further is capable of receiving an alarm notification regarding a device having an associated topology object stored in the database, extracting the topology object, and acting on said topology object update an alarm count in the topology object; propagate the alarm notice to other topology nodes associated with the topology object; store information related to the alarm and the database; and notifying other services on the computer network. Other embodiments update the relationships between the devices and associated topology objects stored in the database.
