Abstract: An electronic device for skin management or skin treatments including an active area including a light emission area and a non-light emission area comprises a plurality of organic light emitting devices disposed in the light emission area and emitting same color light; and first to third wavelength converting layers overlapping the light emission area and a part of the non-light emission area, wherein light emitted from the plurality of organic light emitting devices is extracted to outside the electronic device through the first to third wavelength converting layers.
Abstract: In certain embodiments, a system for controlling a position of a focal point of a laser beam comprises a beam expander, a scanner, an objective lens, and a computer. The beam expander controls the focal point of the laser beam and includes a mirror and expander optical devices. The mirror has a surface curvature that can be adjusted to control a z-position of the focal point. The expander optical devices direct the laser beam towards the mirror and receive the laser beam reflected from the mirror. The scanner receives the laser beam from the beam expander and manipulates the laser beam to control an xy-position of the focal point. The objective lens receives the laser beam from the scanner and directs the beam towards the target. The computer receives a depth instruction, and sets actuation parameters to control the surface curvature of the mirror according to the depth instruction.
Abstract: System (1) for treatment by photodynamic therapy comprising an illuminating member (6) which comprises: —a core (35) carrying a light emitting surface (37), and —a hollow sheath (10) adapted to receive the core (35) with the light emitting surface (37) arranged within a balloon (11), the balloon (11) comprising a wall (12) which has an inner surface delimiting an internal space, and an outer surface, the wall (12) being flexible, wherein the internal space of the balloon (11) has a variable capacity, the wall (12) of the balloon (11) being elastically extendible and the balloon (11) presenting a plurality of inflated states in each of which the internal space is filled with a volume of light diffusing solution, and wherein the system further comprises a support provided with a transfer function relating the volume of light diffusing solution of each inflated state with at least one of a corresponding distribution of light power at the outer surface of the wall (12) of the balloon (11) and a corresponding time

Abstract: A robotic surgical system has a user interface with a control arm that includes a passive axis system for maintaining degrees-of-freedom of a gimbal rotatably supported on the control arm as the gimbal is manipulated during a surgical procedure. The control arm includes a swivel member, a first member, and a second member. The swivel member is rotatable about a first axis. The first member rotatably coupled to the swivel member about a second axis that is orthogonal to the first axis. The second member rotatably coupled to the first member about a third axis that is parallel to the second axis. The gimbal rotatably supported by the second member about a fourth axis that is orthogonal to the third axis. The passive axis system correlating rotation of the swivel member about the first axis with rotation of the gimbal about the fourth axis.
Abstract: An implantable device, comprising: an end section, and at least one or a plurality of anchoring elements connected to the end section for anchoring the end section of the implantable device in the tissue of a patient, the anchoring element(s) extending in an extension direction of the anchoring element(s). The anchoring element(s): has an elastically compressible design; can be arranged in a compressed state in which it is folded toward the end section; and is designed to automatically move into an expanded state in which it projects from the end section at an angle of incidence. The anchoring element(s) comprises at least one first lamella and a second lamella connected to the first lamella, and wherein the two lamellae extend along the extension direction of the anchoring element(s) and include a first angle with one another in a plane perpendicular to the extension direction of the anchoring element(s).
Abstract: Electrocardiography (ECG) signals contain important markers for Coronary Heart Disease (CHD). State of the art systems and methods rely on clinically available multi-lead ECG for CHD classification which is not cost effective. Moreover the state of the art methods are applied on digital ECG time series data only. Also, discriminative HRV markers are not often present in short ECG recordings necessitating long hours of ECG data to analyze. In accordance with the present disclosure, systems and methods described hereinafter extract ECG time series from ECG images obtained from commercially available low-cost single lead ECG devices through a combination of image and signal processing steps including Histogram analysis, Morphological operation-thinning, Extraction of lines, Extraction of Reference Pulse, Extraction of ECG and interpolating missing data.
