Patent number: 11740185Abstract: A method of detecting defects in a structure sample comprising a thin film layer and a sacrificial later is disclosed. The method comprises exposing the thin film layer to a vapour phase etchant, obtaining an image of the thin film layer and analysing the image. The vapour phase etchant enhances any defects present in the thin film layer by passing through the defect and etching a cavity within the sacrificial layer. The cavity undercuts the thin film layer resulting in a stress region surrounding the defect. Defects which were not originally detectable may be made detectable after exposure to the vapour phase etchant. A vapour phase etchant has the advantage of being highly mobile such that it can access defects that a liquid phase etchant might not. Furthermore, unlike a liquid phase etchant, a vapour phase etchant can be used to test a sample non-destructively.Type: GrantFiled: August 29, 2019Date of Patent: August 29, 2023Assignee: MEMSSTAR LIMITEDInventors: Anthony O'Hara, Daniel Drysdale

Publication number: 20230155399Abstract: A charge control system includes a lithium battery configured to provide lithium battery power to a set of electrical loads, a user signaling device, and control circuitry coupled with the lithium battery and the user signaling device. The control circuitry is operative to: (A) detect availability of charge from an external charger, (B) in response to detection of the availability of charge from the external charger and prior to controlling the external charger to adjust the amount of charge stored by the lithium battery, perform a set of pre-charging assessment operations, and (C) based on the set of pre-charging assessment operations, provide a user notification via the user signaling device, the user notification indicating whether the lithium battery is properly setup for charge adjustment. When the user signaling device generates the user notification, the user is informed that the utility vehicle is properly connected to the external charger.Type: ApplicationFiled: January 18, 2023Publication date: May 18, 2023Inventors: Luke Anthony O'Hara, Arthur James Harvey

Publication number: 20220388837Abstract: There is provided a method of producing a microstructure that comprises employing a hydrogen fluoride (HF) vapour to etch a sacrificial layer of silicon dioxide (SiO2) and thereafter removing a residual layer formed when HF vapour etching the layer of silicon dioxide. The residual layer may comprise silicon, ammonium salt or carbon and various techniques are disclosed for removing such layers. These techniques may be applied concurrently, or sequentially, to the microstructure. The described methodologies therefore produce microstructures that exhibits reduced levels of residue when as compared to those techniques known in the art.Type: ApplicationFiled: November 12, 2020Publication date: December 8, 2022Inventor: Anthony O'HARA

Patent number: 11124074Abstract: A control system for handling a fault condition on a utility vehicle includes a lithium battery, a contactor configured to control electrical access to the lithium battery, and control circuitry coupled with the lithium battery and the contactor. The control circuitry is configured to detect, while the contactor is closed to provide a set of loads of the utility vehicle with electrical access to the lithium battery, onset of a fault condition. The control circuitry is further configured to perform, in response to detection of the onset of the fault condition, a set of remedial operations to address the fault condition. The control circuitry is further configured to perform, after a predefined amount of time has elapsed since the onset of the fault condition, a subsequent operation which opens the contactor if the fault condition remains and maintains closure of the contactor if the fault condition does not remain.Type: GrantFiled: October 29, 2019Date of Patent: September 21, 2021Assignee: Textron Innovations Inc.Inventors: Arthur James Harvey, Norman R.

Patent number: 11019074Abstract: Methods and systems are described for managing a user's contact data which use evolving sequential sets of rules where the applicability of each set depends upon adherence or proper application of a prior set. In an embodiment, an initial set of restrictions are generated based on input from a first user, the restrictions relating to contact made by a second user to the first user. These initial restrictions are subsequently modified in response to the second user contacting the first user based on the contact made and a characteristic of the contact. The methods may apply to any form of contact between the first and second users and in an embodiment applies to contact made by the second user to a cellular telephone number belonging to the first user.Type: GrantFiled: September 26, 2018Date of Patent: May 25, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Kenton Paul Anthony O'Hara, Michael Anthony Massimi, Matthew Kay, Richard Harper, James William Scott

Patent number: 10354884Abstract: The etching of a sacrificial silicon dioxide (SiO2) portion in a microstructure such as a microelectro-mechanical structures (MEMS) by the use an etchant gas, namely hydrogen fluoride (HF) vapor is performed with greater selectivity to other portions within the MEMS, and in particular portions of silicon nitride (Si3N4). This is achieved by the addition of a secondary non-etchant gas suitable for increase the ratio of difluoride reactive species (HF2? and H2F2) to monofluoride reactive species (F?, and HF) within the HF vapor. The secondary non-etchant gas may comprise a hydrogen compound gas. The ratio of difluoride reactive species (HF2? and H2F2) to the monofluoride reactive species (F?, and HF) within the HF vapor can also be increased by setting an etch operating temperature to 20° C. or below.Type: GrantFiled: January 24, 2012Date of Patent: July 16, 2019Assignee: MEMSSTAR LIMITEDInventor: Anthony O'Hara

Patent number: 10195948Abstract: A technique controls charge on a lithium battery of a utility vehicle. The technique involves operating electronic circuitry of the utility vehicle in a normal operating mode in which the electronic circuitry charges the lithium battery to a normal charge level. The technique further involves, after operating the electronic circuity in the normal operating mode, transitioning the electronic circuitry from the normal operating mode to a storage mode in which the electronic circuitry is configured to set an amount of charge on the lithium battery to within a predefined storage range (or level) which is lower than the normal charge level. The technique further involves, in response to transitioning the electronic circuitry, adjusting the amount of charge on the lithium battery from an initial charge level which is outside the predefined storage range to an adjusted charge level which is within the predefined storage range.Type: GrantFiled: March 7, 2017Date of Patent: February 5, 2019Assignee: Textron Innovations Inc.Inventors: Luke Anthony O'Hara, Arthur James Harvey, John Ledden, Russell William King
