Patent number: 11959942Abstract: A rate of change of current sensor includes two measurement coils, arranged such that the turns of the first and second measurement coils are interleaved. The rate of change of current sensor further comprises two return coils, arranged to progress in an opposite direction to the measurement coils. The coils form loops and progress substantially around a target measurement conductor. This ensures that the two measurement coils both receive the same electrostatic coupling from external conductors which are not the target of the measurement operation. Further, the two measurement coils are arranged such that the first coil and the second coil are, on average, the same distance to the current-carrying conductor of interest.Type: GrantFiled: March 15, 2022Date of Patent: April 16, 2024Assignee: Analog Devices International Unlimited CompanyInventors: Brent William Hoffman, Jonathan Ephraim David Hurwitz

Publication number: 20140372363Abstract: Methods and systems for predicting a proposed electronic mail (email) for an email campaign to be sent to a list of email addresses received from a sender is spam. A hard bounce rate is predicted for the list of email addresses based on hard bounce rates calculated for respective email addresses on the list. If predicted hard bounce rate exceeds a threshold, the proposed email is deemed spam and sender may be informed. If predicted hard bounce rate falls within range of the threshold, proposed email may be sent to less than all the email addresses on list. If an acceptable number of the sent emails are received, the email may be sent to remaining email addresses on list. Prior to sending proposed email, the list of email addresses may be compared to purchased lists of email addresses. If there is a match, the proposed email may be deemed spam.Type: ApplicationFiled: March 17, 2014Publication date: December 18, 2014Applicant: Rocket Science LLCInventors: Ben Chestnut, Nathaniel Bainton, John Foreman, William Hoffman, Chad Morris, Cass Petrus, Sean Sawyer, Joe Uhl

Patent number: 8839753Abstract: A corona igniter 20 includes an electrode gap 28 between the central electrode 22 and the insulator 32 and a shell gap 30 between the insulator 32 and the shell 36. An electrically conductive coating 40 is disposed on the insulator 32 along the gaps 28, 30 to prevent corona discharge 24 in the gaps 28, 30 and to concentrate the energy at a firing tip 58 of the central electrode 22. The electrically conductive coating 40 is disposed on an insulator inner surface 64 and is spaced radially from the electrode 22. The electrically conductive coating 40 is also disposed on the insulator outer surface 72 and is spaced radially from the shell 36. During operation of the igniter 20, the electrically conductive coating 40 provides a reduced voltage drop across the gaps 28, 30 and a reduced electric field spike at the gaps 28, 30.Type: GrantFiled: December 29, 2011Date of Patent: September 23, 2014Assignee: Federal-Mogul Ignition CompanyInventors: John Antony Burrows, James D.
