Patent number: 11003046Abstract: A photonic device comprises a plurality of resonators and a plurality of optical channels. Each resonator from the plurality of resonators has a set of resonance frequencies independently selected from a set of resonance frequencies of each remaining resonator from the plurality of resonators. Each resonator from the plurality of resonators lacks substantially any linear coupling between each remaining resonator from the plurality of resonators. The plurality of resonators defines a spatial overlap region between at least two resonators from the plurality of resonators such that nonlinear optical processes are substantially optimized during operation. A plurality of optical channels is operatively coupled to the plurality of resonators. The plurality of optical channels is configured to receive light from the plurality resonators and configured to send light into the plurality of resonators.Type: GrantFiled: December 1, 2020Date of Patent: May 11, 2021Assignee: Xanadu Quantum Technologies Inc.Inventors: Marco Liscidini, Matteo Menotti, Blair Morrison, John Sipe, Kang Tan, Zachary Vernon

Patent number: 10676060Abstract: In a method of folding an airbag (10) for a vehicle occupant restraint system, especially of curtain-type side airbag, to form an airbag package (12?), the airbag (10) is rolled and/or folded to form an airbag roll (12) having a first volume (V1). The airbag roll (12) is fed to a pressing device (14) in which the airbag roll (12) is compressed to form an airbag package (12?) having a second volume (V2) which is smaller than the first volume (V1). The airbag roll (12) and, resp., the airbag package (12?) is heated within the pressing device (14) and the airbag package (12?) is cooled, with the airbag package (12?) retaining the second volume (V2) when it is removed from the pressing device (14; 114). The pressing device (14) includes a pressing mold or a molding shaft (18) whose height substantially corresponds to the desired height of the finished airbag packages (12?), a heating unit (20) for heating the airbag packages (12?) and a cooling device (22) for cooling the airbag packages (12?).Type: GrantFiled: August 19, 2016Date of Patent: June 9, 2020Assignees: TRW AUTOMOTIVE GMBH, TRW VECHICLE SAFETY SYSTEMS INC.Inventors: Anton Fischer, Michelle Blackson, Dylan Moran, Blair Morrison

Patent number: 9673908Abstract: Disclosed herein is a notch filter and a method for generating an electrical signal with a suppressed frequency band. The filter generates an optical signal by modulating a modulation optical wave with an electrical signal to generate first and second sidebands. The first sideband or the second sideband has less power than the other. The filter then modifies the optical signal by equalizing the power of light within the first side band at a selected frequency band and light within the second side band at the selected frequency band. The filter then produces an antiphase relationship between the light within the first side band at the selected frequency band and the light within the second side band at the selected frequency band. The filter then detects the modified optical signal to generate a copy of the electrical signal with suppressed frequency components within the selected frequency band.Type: GrantFiled: June 18, 2014Date of Patent: June 6, 2017Assignee: The University of SydneyInventors: David Marpaung, Blair Morrison, Ravi Pant

Patent number: 5810444Abstract: A latch mechanism latches a seat back (40), which is moveable relative to a seat base (20) between an upright position and a folded position. The latch mechanism comprises a pawl (60) connected with the seat back (40). The pawl (60) is moveable relative to the seat back (40) between an engaged position in which the pawl (60) is effective to prevent movement of the seat back (40) from the upright position and a disengaged position in which the pawl (60) is ineffective to prevent movement of the seat back (40) from the upright position. The latch mechanism further comprises a retaining member (100) connected with the seat back (40). The retaining member (100) is moveable from a first position to a second position upon movement of the seat back from the upright position. The retaining member (100) is effective to retain the pawl (60) against movement to the engaged position relative to the seat back (40) when the retaining member (100) is in the second position.Type: GrantFiled: June 25, 1997Date of Patent: September 22, 1998Assignee: TRW Vehicle Safety Systems Inc.Inventors: Lawrence M.
