Abstract: A machine for making filled pasta includes first and second feeding device for feeding first and second layers of pasta dough, and a shaping device for shaping the filled pasta, located downstream of the feeding devices. The machine controls the advancing of the first and second layers the respective feeding device such that at least along a first stretch of the path of the first layer between the first feeding device and the shaping device, an excess length of the first layer of pasta dough forms by gravity a respective bend along the unrolling direction and at least along a first stretch of the path of the second layer between the second feeding device and the shaping device, an excess length of the second layer of pasta dough forms by gravity a respective bend along the unrolling direction.

Abstract: A power converter is presented. The power converter may be configured to receive an input voltage at an input node of the power converter and to generate an output voltage at an output node of the power converter. The power converter may comprise an inductor coupled between an inductor node and the output node. The power converter may comprise a flying capacitor coupled between a first capacitor node and a second capacitor node. The power converter may comprise a first switching element coupled between the input node and the first capacitor node. The power converter may comprise a second switching element coupled between the second capacitor node and the inductor node. The power converter may be configured to, during a first phase of a buck operation mode, open the second switching element such that the second capacitor node is isolated from the inductor node.

Abstract: Systems and methods for an improved dosimeter for measuring dosage for photodynamic therapy treatment are provided. An example systems includes a dosimeter comprising a variable optical filter system configured to receive a second light, the second light comprising luminescence produced by singlet oxygen and one or more background signal and selectively transmit the luminescence and the one or more background signals as a third light, the variable optical filter system comprises a plurality of optical bandpass filters that are switchable to selectively transmit the luminescence and the one or more background signals. The dosimeter also includes a photoreceiver configured to receive the third light and configured to generate electrical output signals corresponding to the luminescence and the one or more background signals, the electrical output signals being indicative of an amount of the singlet oxygen produced based on activating the photosensitizer.

Abstract: System for combined intraoperative aberrometry and optical coherence tomography (OCT). In an embodiment, the system comprises an OCT system, an aberrometer, a beam delivery system, and a beam splitter. The beam delivery system is configured to output a beam towards a target, wherein the beam has an outward path to the target and a return path after being reflected by the target. The beam splitter is positioned in the return path of the beam and configured to split the return path into a first path to the OCT system and a second path to the aberrometer. Thus, the OCT system and aberrometer can share a single beam delivery system.

Abstract: Systems, methods and apparatuses for an intraocular imaging system are disclosed comprising an optical coherence tomography (OCT) system. The OCT system has an imaging range that may enable substantial portions of an eye or even a whole eye to be imaged. The OCT system may be coupled to an operation microscope, such that, for example, a surgeon can visualize ocular structures like the human crystalline lens and other ocular structures such as the cornea and/or vitreous while surgical instruments are in the field of view.

Abstract: In some embodiments, images of a cornea may be obtained, and the images of the cornea may be segmented to detect a tear film layer of the cornea and an epithelium layer of the cornea. Thickness of the tear film layer and thickness of the epithelium layer may be determined based on the segmentation of the images of the cornea. A thickness map may be generated based on the thickness of the tear film layer and the thickness of the epithelium layer. As an example, the thickness map may comprise visual differences in thickness across the tear film layer and the epithelium layer. In some embodiments, the foregoing may be performed with respect to one or more other microlayers of the cornea in addition to or alternatively to the tear film layer or the epithelium layer.
