Title: Optical sensor system
Inventor: KAYVON BARAD
IPC: G01J9/02
Filed: 2018-05-11
Abstract: An optical sensor system has at least two fiber Bragg grating (FBG) sensors 1a, 1b. An optical de-multiplexing system 21, e.g. a series chain of drop de-multiplexers 21a, 21b, routes light to associated receivers. Each receiver comprises a detector 31a, 31b and a slope filter 30a, 30b, which may have a pass-band corresponding to the drop band 25a, 25b of the de-multiplexers. The filters’ wavelength gain function 32a, 32b attenuates according to wavelength, allowing identification of the light reflected by the FBG sensors. A light source 10 e.g. a LED or laser diode may be used. The system may be used to interrogate multiple sensors for e.g. aircraft ventilation monitoring or high frequency motor synchro feedback and control (figs 4-6). An interrogation fibre 9 and first circulator 13 may be used. Also disclosed is a system comprising a beam splitter forming a reference and measurement beam from a fibre grating.

Title: Vehicle door assistance
Inventor: MAHMOUD YOUSEF GHANNAM
IPC: E05F15/72
Filed: 2018-06-12
Abstract: Vehicle door assistance with a solenoid coupled between a door and a frame to provide a door adjustment force when the door is opening/closing. Door assisting adjustment force is based on roll and pitch angles of the vehicle and a personal characteristic of an occupant. An accelerometer may measure the vehicle angle. The personal characteristic may be based on age, strength, and may sense when an occupant is struggling to open a door and may adjust the level of assisting force. A user interface may allow entry of multiple different user assistance profiles which can be applied to different doors. Preferably an emergency mode can be selected by a manual switch or automatically in the event of a collision which may unlock the doors and when a user grasps the handle automatically opens the door. Triggering of an air-bag may automatically select the emergency mode.

Title: Acquirerless transaction card processing systems and methods
Inventor: Nagarajan Rangarajan
IPC: G06Q30/02
Filed: 2018-07-30
Abstract: The application relates to scheduled automated payments via a non-acquirer bridging account. Customer data including transaction card source account, non-acquirer recipient account, payment amount and scheduled payment date are received by an enrolment processor 302. An automated bill payment processor debits the payment amount from the transaction card source account 308 and credits the payment amount to the non-acquirer bridging account 310 on a payment initiation date a number of days before the scheduled payment date 306. On or before the scheduled payment date, the automated bill payment processor debits the payment amount from the non-acquirer bridging account 312 and transfers the payment amount to the non-acquirer recipient account 36 via a non-card association channel, such as intrabank transfer 314. Database screening checks 304 of the parties against a list of prohibited entities may be performed. Authorisation checks, such as confirming available balance, account delinquency or transaction velocity, may be triggered. The system may enable customers to make payments using their credit card to recipients without merchant accounts, such as a tenant paying rent to a landlord, thus earning customer incentives such as reward points, airline miles or cashback by using their credit card for the payment.

Title: Speaker recognition
Inventor: JOHN PAUL LESSO
IPC: G10L17/10
Filed: 2019-01-21
Abstract: A biometric is formed for an enrolled speaker by obtaining a measure of the fundamental frequency (pitch) in each of a plurality of speech frames from a speech sample obtained from the speaker. A reference distribution is formed of the fundamental frequency of the enrolled speaker’s speech. A speaker is subsequently recognised by obtaining a sample of their speech, forming a second distribution of the fundamental frequency of that sample, and comparing it to the reference distribution. The distributions may be cumulative distribution functions, and the comparison between distributions may include calculating a statistical difference. The comparison may be combined with alternative biometrics such as formant-dependent features, or other features of the fundamental frequency such as jitter, shimmer or trajectory of the fundamental frequency. Also disclosed is a method of speaker change detection where fundamental frequency is measured during several time periods and compared with earlier measurements.

Title: Multi-functional ion mobility separator
Inventor: STEVEN DEREK PRINGLE
IPC: H01J49/40
Filed: 2019-05-13
Abstract: An ion mobility separator comprises a plurality of closed-loop ion guides (1a, 1b, 1c…) that are interconnected, e.g. using one or more interconnecting ion guides 3, such that ions can travel between and around the closed loop ion guides. The interconnecting ion guide may intersect each closed-loop ion guide at a respective transfer region 4. Each transfer region may be controlled to (i) divert ions received from an interconnecting ion guide to travel around the closed-loop ion guide; (ii) divert ions out from the closed-loop ion guide and along an interconnecting ion guide, or (iii) allow ions received from an interconnecting ion guide to pass through without being diverted around the closed-loop ion guide. Each transfer region may operate in different modes at different times, such that different ions have different paths through the separator. Ions may be separated according to their mobilities and/or fragmented or reacted when they travel around the closed loop ion guides. A mass spectrometer comprising the ion mobility separator is also claimed.
