Abstract: A method (6) for inspecting an ophthalmic lens (2), in particular a contact lens such as a soft contact lens (2), in an automated lens manufacturing process is disclosed. The method comprises the steps of acquiring (60) a plurality of images containing the ophthalmic lens (2) to be inspected as an imaged ophthalmic lens (2), wherein each image (4) of the plurality of images is of a different image type, registering (63) the plurality of images by applying a registration function to each image (4) of the plurality of images to obtain registered images, determining (64), based on the registered images, whether the ophthalmic lens (2) complies with predetermined specifications, and updating (62) the registration function to compensate for possible changes in the acquisition of the plurality of images. Updating (62) the registration function is performed during the automated lens manufacturing process.

Abstract: In a method of handling an ophthalmic lens contained in an inspection cuvette and immersed in an inspection liquid the lens is arranged at an actual position relative to a concave inner surface of a bottom glass of the inspection cuvette; The method comprises the steps of: positioning the inspection cuvette in a handling position without pivoting the inspection cuvette; through the viewing glass obtaining an image of the lens; from the obtained image determining a deviation of the actual position of the lens from a set transfer position; comparing the deviation with a predetermined maximum deviation; determining that the lens is arranged at a proper transfer position when the deviation is less than the maximum deviation, in case of the proper transfer position, transferring the lens from the inspection cuvette to the primary packaging container.

Abstract: An inspection cuvette for the optical inspection of an ophthalmic lens comprises a hollow cuvette body defining a cavity for receiving the ophthalmic lens and an inspection liquid, a transparent bottom having a concave upper surface delimiting the cavity at a bottom end thereof, a handling channel having an inner circumferential channel wall and a longitudinal channel axis. The handling channel further has an access opening at a proximal end thereof and is connected to the cavity at a distal end thereof. The inspection cuvette further comprises and an inspection window comprising a flat lower surface delimiting the cavity at an upper end thereof and facing towards the concave upper surface of the transparent bottom. At least that portion of the inner circumferential channel wall which is arranged above the flat lower surface of the inspection window when the cuvette is arranged in an inspection position is round.

Abstract: A method is disclosed for designing a local coil to be used in a combined PET magnetic resonance device for magnetic resonance imaging in relation to the arrangement of radiation-attenuating electronic elements in an irradiation area for PET photons. In an embodiment of the method, taking into consideration at least one boundary condition specifying the degree of freedom of the positioning of the electronic elements, optimization of the positions of the electronic elements is undertaken in an optimization method in respect of a uniform distribution of attenuation centers which is as substantial as possible.

Abstract: A magnetic resonance apparatus includes a patient couch with a couch surface on which a patient is supportable. In the patient couch, lower local coils for receiving excited magnetic resonance signals of the patient are arranged below the couch surface. On an upper side of the patient couch, connecting devices are arranged to sides. The magnetic resonance device includes upper local coils that are detachably connected mechanically and electrically with the connecting devices. The lower local coils and the upper local coils are connected to electronics that at least include a respective pre-amplifier and are connected via connection lines arranged outside the patient couch to an evaluation device. In a state in which the upper local coils are connected to the connecting devices, the upper local coils are fixed mechanically to the patient couch and cover the patient in a dome shape. The electronics are arranged in the patient couch.

Abstract: A support unit is disclosed for positioning a patient within a medical imaging apparatus with at least one magnetic resonance device; along with a patient positioning apparatus and a medical imaging apparatus including such a support unit. In an embodiment, the support unit includes at least one bearing element for movable positioning relative to a patient positioning apparatus and a coil unit for receiving magnetic resonance raw data. The coil unit includes a flat supporting surface for positioning the patient.

Abstract: A method, a computer program product and a computer readable storage medium are disclosed for generating a global attenuation map used for attenuation correction of positron emission tomography image data sets in a combined magnetic resonance-positron emission tomography device. In an embodiment, during the course of detecting hardware components of the combined magnetic resonance-positron emission tomography device and determining positions of the detected hardware components relative to a patient support, the global attenuation map is generated as a function of the detected hardware components.

Abstract: A method and apparatus for reducing undesirable air flow in a passenger compartment of a forward moving vehicle taps into an external air stream source to provide a counteractive air flow supply. The counteractive air flow supply is used to introduce at least one generally forward to rearward directed counteractive flow of air into the passenger compartment at a generally laterally central portion of the vehicle in an amount and at a velocity sufficient to counteract at least a portion of a rearward to forward flow of air in the passenger compartment to provide a forward to rearward directed flow of air through a generally laterally central portion of the passenger compartment at a head level of at least one front seat passenger.
