Patent number: 8749945Abstract: A corona ignition system 20 includes a corona drive circuit 26 and an auxiliary energy circuit 28. The energy circuit 28 stores energy during a standard corona ignition cycle. When arc discharge occurs or corona discharge switches to an arc discharge, the energy circuit 28 discharges the stored energy to the electrode 30 to intentionally maintain a robust arc discharge 29 and thus provide reliable ignition. The stored energy is transmitted to the electrode 30 over a predetermined period of time. The arc discharge is detected and an arc control signal 60 is transmitted to the energy circuit 28, triggering discharge of the stored energy to the electrode 30. The stored energy can be transmitted to the electrode 30 along a variety of different paths. The voltage of the stored energy is typically increased by an energy transformer 70 before being transmitted to the electrode 30.Type: GrantFiled: August 31, 2011Date of Patent: June 10, 2014Assignee: Federal-Mogul IgnitionInventors: John Antony Burrows, James D.

Patent number: 8710456Abstract: A multi-sectional linear ionizing bar with at least four elements is disclosed. First, disclosed bars may include at least one ionization cell with at least one axis-defining linear ion emitter for establishing an ion cloud along the length thereof. Second, disclosed bars may include at least one reference electrode. Third, disclosed bars may include a manifold for receiving gas or air from a source and for delivering same past the linear emitter(s) such that substantially none of the gas/air flows into the ion cloud. Fourth, disclosed bars may include means for receiving the ionizing voltage and for delivering same to the linear emitter(s) to thereby establish the ion cloud. In this way, disclosed ionizing bars may transport ions from the plasma region toward a charge neutralization target without inducing substantial vibration of the linear emitter and without substantial contaminants from the gas/air flow reaching the linear emitter.Type: GrantFiled: July 22, 2013Date of Patent: April 29, 2014Assignee: Illinois Tool Works Inc.Inventors: Aleksey Klochkov, Peter Gefter, Steven Bernard Heymann, Leslie W.

Patent number: 8688829Abstract: The method for binding a sensor and an actuator can be categorized into three types: manual binding, automatic binding and semi-automatic binding. Manual binding methods increase users' operational burden when a great number of sensors and actuators are to be bound. The current hard-coded automatic binding method suffers from lack of versatility. The template-based semi-automatic binding method still requires users to input some information manually. The disclosure provides an automatic binding method, which can automatically and reasonably bind the functions of a sensor and an actuator without user input, in a sensor network comprising a plurality of sensors and actuators.Type: GrantFiled: September 19, 2011Date of Patent: April 1, 2014Assignee: Industrial Technology Research InstituteInventors: Yueh Feng Lee, Hsin Sheng Liu, Ming Shyan Wei, Yang Jung Li

Patent number: 8531848Abstract: A first insulated planar metallic surface is formed under a surface of a substrate which is orientated a first way to an edge of the substrate. A Faraday shield is formed when a second insulated planar metallic surface is juxtaposed to and segregates the first insulated planar metallic surface from the remained of the substrate. The first way can be parallel or perpendicular forming either an edge or surface Coulomb island, respectively. Both planar surfaces can be charged either by mechanical contact or induced charging, Fowler-Nordheim and ion implantation. A Coulomb force is generated between two charged Coulomb islands each located on a different substrate. In addition, these Coulomb islands can also be used as capacitors to transfer signals between the substrates. The Faraday shield can be used to increase the Coulomb force while the potential applied to the shield can alter the Coulomb force.Type: GrantFiled: December 7, 2007Date of Patent: September 10, 2013Assignee: MetaMems Corp.Inventor: Thaddeus John Gabara
