Publication number: 20240103299Abstract: Adjustable focal length eyewear (11) comprising two lenses (21, 22) that are mounted to a frame (14, 15, 16) for supporting the lenses (21, 22) in front of a user's eyes. At least one of the lenses (21, 22) is a variable focal length lens of the kind comprising two superposed lens elements (31, 41) having cooperating optical surfaces that are shaped such that the focal length of the variable focal length lens (21, 22) is variable according to the relative lateral disposition of the lens elements (31, 41). One of the lens elements (31) is fixedly mounted to the frame (14, 15, 16) and the other lens element (41) is movable manually relative to the fixed lens element (31) for varying the focal length of the variable focal length lens (21, 22).Type: ApplicationFiled: October 9, 2020Publication date: March 28, 2024Applicant: ADLENS LTDInventors: Robert PERKINS, Alex EDGINGTON, Paul MASSER, Andrew LAST

Publication number: 20230210419Abstract: A process for calibrating a glucose sensor under sterile conditions includes providing separate, sterile, glucose-containing calibration fluids, each having a different glucose concentration, and in turn providing these fluids to a sensing zone containing a sensing probe of a glucose sensor. Each solution is typically, in turn, propelled into the sensing zone, thus flushing out used fluid already present in the sensing zone. The process provides rapid calibration of a glucose sensor in a sterile fashion and is therefore appropriate for point-of-use calibration.Type: ApplicationFiled: March 10, 2023Publication date: July 6, 2023Inventors: Barry Colin Crane, Nicholas Paul Barwell, William Paterson, Robert Perkins

Patent number: 11554217Abstract: A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device.Type: GrantFiled: April 14, 2020Date of Patent: January 17, 2023Assignee: Sanofi-Aventis Deutschland GMBHInventors: Robert Frederick Veasey, Robert Perkins, David Aubrey Plumptre

Patent number: 11160928Abstract: The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose-cartridge and permit a user to set the delivery dose. The injector may include a housing, a piston rod adapted to operate through the housing, a dose dial sleeve located between the housing and the piston rod, and a drive sleeve located between the dose dial sleeve and the piston rod. The dose dial sleeve may have a helical thread of first lead and the drive sleeve may have a helical groove of second lead. The first lead of the helical thread and the second lead of the helical groove may be the same.Type: GrantFiled: August 21, 2017Date of Patent: November 2, 2021Assignee: Sanofi-Aventis Deutschland GMBHInventors: Robert Frederick Veasey, Robert Perkins, David Aubrey Plumptre

Publication number: 20200054254Abstract: A process for calibrating a glucose sensor under sterile conditions includes providing separate, sterile, glucose-containing calibration fluids, each having a different glucose concentration, and in turn providing these fluids to a sensing zone containing a sensing probe of a glucose sensor. Each solution is typically, in turn, propelled into the sensing zone, thus flushing out used fluid already present in the sensing zone. The process provides rapid calibration of a glucose sensor in a sterile fashion and is therefore appropriate for point-of-use calibration.Type: ApplicationFiled: October 3, 2019Publication date: February 20, 2020Inventors: Barry Colin Crane, Nicholas Paul Barwell, William Paterson, Robert Perkins
