Publication number: 20180194314Abstract: An impact detection system is disclosed for detecting and identifying an object colliding with a vehicle. The impact detection system comprises a sensor arrangement arranged to measure a characteristic of an impact of the object against the vehicle, a trigger determiner associated with the sensor arrangement for determining whether the characteristic of the 5 impact is greater than a predefined threshold value, and an image capturing device arranged to capture an image of the object. The system is arranged to automatically make the captured image available for inspection in response to the trigger determiner determining that the characteristic of the impact is greater than the predefined threshold value so that the object in the image can be identified substantially in real-time.Type: ApplicationFiled: July 14, 2016Publication date: July 12, 2018Inventors: Ilidio Gouveia Da Costa, Anthony Michael Godber, David Wallis, Matthew Shurmer, Paul Nicholson, Gareth Topham, Richard Pearman, Peter Knight

Publication number: 20180166847Abstract: A device and method for tuning a ring resonator using self-heating stabilization is provided. A light source is controlled to produce an optical signal, input to an optical ring resonator, at a power where self-heating shifts a resonance wavelength of the optical ring resonator by at least 10 picometers, the self-heating comprising absorption in the optical ring resonator of optical power from a received optical signal. Prior to using the optical ring resonator at least one of modulate and filter the optical signal at the optical ring resonator, a heater of the optical ring resonator is controlled to an operating temperature at which the resonance wavelength of the optical ring resonator is greater than a respective wavelength of the optical signal.Type: ApplicationFiled: February 9, 2018Publication date: June 14, 2018Inventors: Bin CAO, Dylan LOGAN, Douglas J.

Patent number: 9946027Abstract: A device and method for post-fabrication trimming of an optical ring resonator using a dopant-based heater is provided. An optical ring resonator at the device can be heated using heaters in an optical slab from which the optical ring resonator extends, the heater including a non-uniform doping profile. A controller determines an initial resonance frequency and a target resonance frequency of the optical ring resonator. The controller applies predetermined electrical parameters to the heater using electrical connections to shift a resonance frequency of the optical ring resonator from the initial resonance frequency to the target resonance frequency by causing the dopant in the heater to migrate.Type: GrantFiled: March 10, 2016Date of Patent: April 17, 2018Assignee: RANOVUS INC.Inventor: Andrew Peter Knights

Patent number: 8394179Abstract: A method is described for treating a gas stream containing a flammable gas, such as hydrogen or a hydrocarbon gas. The gas stream is conveyed to a liquid ring pump (18), to which a gaseous oxidant and water are supplied. The water and the gas stream are discharged from the pump (18), with the discharged gas stream being subsequently separated from the liquid, and conveyed to a pyrolysis device (42) for pyrolysing the flammable gas and the oxidant. Any particulates and acidic species within the gas stream are retained by the water within the liquid ring pump to inhibit corrosion or blockage of the pyrolysis device (42). A filter or other device (40) may be provided to remove water from the gas stream before it enters the pyrolysis device (42).Type: GrantFiled: January 23, 2008Date of Patent: March 12, 2013Assignee: Edwards LimitedInventors: James Robert Smith, Gary Peter Knight

Patent number: 8326094Abstract: The sensor includes an optical waveguide defined in a light-transmitting medium. The waveguide includes a sensing portion and an non-sensing portion. The light-transmitting medium included in the sensing portion has defects that provide the light-transmitting medium with a deep band gap level between a valence band of the light-transmitting medium and a conduction band of the light-transmitting medium. The deep band gap level is configured such that the waveguide guiding light signals through the light-transmitting medium in the sensing portion causes free carriers to be generated in the light-transmitting medium. A detector is configured to detect the free carriers in the sensing region of the waveguide.Type: GrantFiled: September 17, 2010Date of Patent: December 4, 2012Assignee: Kotura, Inc.Inventors: Andrew Peter Knights, Adrian Petru Vonsovici, Dominic Joseph Brady, Andrew Alan House, George Frederick Hopper
