Publication number: 20240147892Abstract: A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.Type: ApplicationFiled: October 23, 2023Publication date: May 9, 2024Inventors: Elijah B. Garner, Daniel B. Thiemke, David J. Rylander, Nathan A. Mariman, Michael E. Friestad

Patent number: 7716808Abstract: Electro-dynamic loudspeakers typically include a diaphragm having a conductor applied to one of its surfaces where the diaphragm is secured to a frame. The conductor is connected to a power supply for providing electrical current through linear traces of the conductor that interact with magnetic fields generated by magnets that are mounted to the frame. The diaphragm is driven by a motive force created when current passes through the conductor within the magnetic field. The electrical current is varied to create an acoustical output from the electro-dynamic loudspeaker. Different methods of attaching the diaphragm are provided for simplifying the manufacturing process and for obtaining a robust electro-dynamic loudspeaker.Type: GrantFiled: December 28, 2007Date of Patent: May 18, 2010Assignee: Harman International Industries, IncorporatedInventors: Steven W. Hutt, John F. Steere, David B. Garner, Louis A. Mango

Patent number: 7627134Abstract: An electro-dynamic loudspeaker includes a frame, a magnet and a diaphragm. The frame includes a body portion defining a magnet mounting surface as well as a plurality of protrusions extending from the magnet mounting surface. The magnet is magnetically attracted to the body portion of the frame. The magnet is restricted from movement along the magnet mounting surface by at least one protrusion. The diaphragm is spaced apart from the magnet and coupled to the frame.Type: GrantFiled: September 16, 2004Date of Patent: December 1, 2009Assignee: Harman International Industries, IncorporatedInventors: David B Garner, Richard J Herold

Patent number: 7236608Abstract: Electro-dynamic loudspeakers typically include a diaphragm that is secured to a frame and has a conductor applied to at least one surface of the diaphragm. The conductor is connected to a power amplifier for providing electric current through the linear traces of the conductor that interact with magnetic fields generated by magnets that are mounted to the frame. The interaction between the current passing through the conductor and the magnetic fields cause vibration in the diaphragm that creates the sound that is heard from the electro-dynamic loudspeaker. Different methodologies of forming the conductor are provided for simplifying the manufacturing process and for locating the conductor closer to the magnetic field generated by the magnets.Type: GrantFiled: May 2, 2003Date of Patent: June 26, 2007Assignee: Harman International Industries, IncorporatedInventor: David B. Garner

Patent number: 7203332Abstract: An electro-dynamic loudspeaker includes a frame, a plurality of magnets and a diaphragm. The frame includes a molded plastic body. The magnets may be molded into the frame in a determined configuration. The frame is mechanically coupled to the diaphragm such that the magnets are a determined distance from the diaphragm. The diaphragm may include a conductor applied to a surface of the diaphragm. The diaphragm may be driven by a motive force created when current passes through the conductor within a magnetic field formed by the magnets. The electrical current may be varied to create an acoustical output from the electro-dynamic loudspeaker.Type: GrantFiled: May 2, 2003Date of Patent: April 10, 2007Assignee: Harman International Industries, IncorporatedInventors: Steven W.

Patent number: 7146017Abstract: An electro-dynamic loudspeaker is typically provided with a diaphragm mounted to a frame in tension. The diaphragm is provided with a plurality of electrical traces that are disposed within a magnetic field of a plurality of magnets that are mounted to the frame. Electric current applied to the circuit causes electric current to pass through the wiring that interacts with the magnetic field of the magnets to thereby cause vibration of the diaphragm that causes the sound generated by the electro-dynamic loudspeaker. Electrical connector arrangements and methods are provided for connecting the electric circuit of the diaphragm to a power amplifier.Type: GrantFiled: May 2, 2003Date of Patent: December 5, 2006Assignee: Harman International Industries, IncorporatedInventors: John F.

Patent number: 7136501Abstract: An electro-dynamic loudspeaker is provided with dampening arrangements that contribute to improved acoustical properties for the electro-dynamic planar loudspeaker. The dampening arrangements include providing a frame having a curved sidewall surface for reducing standing waves. Another design provides for a ferrofluid being disposed between the diaphragm and magnets of the electro-dynamic loudspeaker in order to dampen the resonance frequency of the device. In addition, a diaphragm of an electro-dynamic loudspeaker is provided with a short turn of conductor disposed along a fringe zone at an edge of the diaphragm in order to electro-dynamically dampen the edge resonance of the film.Type: GrantFiled: January 19, 2005Date of Patent: November 14, 2006Assignee: Harman International Industries, IncorporatedInventors: John F Steere, David B.
