Publication number: 20230168181Abstract: Specimens for evaluating corrosion protection of substrates due, at least in part, to coatings applied thereupon are described. A specimen (1) comprises: a first coating (10), comprising a first set of layers (11) including a first layer (11A), on a first substrate (12); and a first set of perforations (100), including a first perforation (100A) and a second perforation (100B), in the first coating (10), wherein the first perforation (100A) has a first depth D1 through the first coating (10) and a first dimension W1 transverse to the first depth, wherein the second perforation (100B) has a second depth D2 through the first coating (10) and a second dimension transverse to the second depth D2 and wherein the first dimension W1 and the second dimension W2 are different.Type: ApplicationFiled: May 26, 2021Publication date: June 1, 2023Applicant: BAE Systems plcInventors: Rebecka Eley, Mark David Balmond, Christopher Colin Figgures, Ian Michael Sturland, Simon Robert Church

Publication number: 20230067030Abstract: A method for forming a MEMS structure for an inertial sensor from fused silica includes: depositing a conductive layer on one or more selected regions of a first surface of a fused silica substrate, and illuminating areas of the fused silica substrate with laser radiation in a pattern defining features of the MEMS structure for an inertial sensor. A masking layer is deposited at least on the one or more selected regions of the first surface of the fused silica substrate where the conductive layer has been deposited, such that the illuminated areas of the fused silica substrate remain exposed. A first etch of the exposed areas of the fused silica substrate is performed so as to selectively etch the pattern defining features of the MEMS structure for an inertial sensor.Type: ApplicationFiled: August 22, 2022Publication date: March 2, 2023Inventors: Christopher Paul Fell, Ian Michael Sturland, Tracey Ann Hawke

Patent number: 9752977Abstract: A corrosion sensor for detecting the action of corrosive media on a metallic component when the sensor is mounted in the vicinity of the metallic component in use is disclosed. The sensor includes an electrically conducting corrodible element mounted on a non conducting substrate, the corrodible element being covered with a protective coating such as paint adapted to protect the corrodible element from corrosive media. The protective coating defines a temporary feature such as a paint defect which extends across the corrodible element and is designed to permit attack on the corrodible element by corrosive media after a predetermined period of time. The corrodible element comprises a pair of spaced tracks extending generally in a longitudinal direction and a series of corrodible tracks, each corrodible track extending generally in a lateral direction and forming an electrical connection between the spaced tracks.Type: GrantFiled: July 2, 2013Date of Patent: September 5, 2017Assignee: BAE SYSTEMS plcInventors: Mark David Balmond, Mark Alcuin Venables, Ian Michael Sturland, Alan Peter Pritchard

Patent number: 8663789Abstract: Improved thin film getter devices (300, 500) comprise a layer (350, 550) of getter material deposited on a substrate (320, 520). The layer has a main portion (340, 540) and a cap portion (360, 560), which forms an external surface of the device. The cap portion has a lower specific area than the main portion.Type: GrantFiled: November 28, 2007Date of Patent: March 4, 2014Assignee: BAE SYSTEMS plcInventors: Ian Michael Sturland, Tracey Anne Hawke

Patent number: 8596462Abstract: A separator is disclosed for separating particles of at least first and second mass/size ranges from an ambient fluid (e.g. gaseous) medium in which they are present, particles of the first range being of generally larger size/mass than particles of the second range. The separator is especially designed for use in an air monitoring device which is designed for rapid detection of micro-organisms such as bacteria, viruses, pathogens and the like, and is designed to be portable so that it can be readily and rapidly deployed in both civilian and military environments and can be used indoors and outdoors; it can also be designed for personal use.Type: GrantFiled: September 9, 2005Date of Patent: December 3, 2013Assignee: BAE Systems PLCInventors: Alexander Roy Parfitt, Ian Michael Sturland, Clyde Warsop, Paul James Dawson
