Abstract: A security lighting system and method are intended to dispel and/or affect unwanted humans or animals by providing lighting that varies with a suitable switching frequency, such as between 5 and 70 Hz. The lighting of a light source of the system may be varied by a control unit as to intensity, color, pattern etc., with a preferred switching frequency being between about 15 and 20 Hz for humans. A proximity detector may be provided to activate the system when an unwanted presence is detected. Such varying lighting causes feelings of physical and psychological discomfort, which have found to be effective in chasing away animals and dispelling or disorienting humans.

Abstract: Cross over (S560) in a genetic algorithm (128) is adapted for deriving an optimal mask (S540), or set of segments of a line. Each mask of a chromosome is subject to cross over with the respective mask of the other parent. Any overlapping part, whether a filtering (320) or pass-through part (350), is retained in the child (334) to preserve commonality. The part is preferably, potentially extended, according to one parent or the other, as decided pseudo-randomly (430). In a preferred application, spectrums of candidate blood constituents are masked for fitting to ensemble spectrums of test blood samples (S610, S620). The developed masks are applicable to constituent spectrums to create masked spectrums (S710) which are then applicable to an actual blood sample to be analyzed (S720).

Abstract: The present invention relates to a multiple LED driver circuit in which each LED (15, 17) is controlled by a bypass switch (19, 21). The LEDs are supplied by a switched mode power supply (8) and are connected to a constant current source to draw a predetermined current through the LEDs. The switched mode power supply is arranged to output different voltages depending on the number of switched-on LEDs. This is carried out by supplying the control signals (sw1, sw2) of the bypass switches to the switched mode power supply. In this way, the power dissipation of the constant current source can be kept at a low level.

Abstract: A light emitting device (100) is provided, comprising a substrate (101), a first electrically conductive layer (102), a light emitting layer (103), and a second electrically conductive layer (104).

The at least one metal shunt (105) is isolated from said second electrically conductive layer (104) at least by means of a dielectric oxide layer (106). The present invention allows for the use of electrically insulating material between one or more metal shunts and a cathode layer without reducing the effective pixel area of the device.

According to the invention, a method of arbitration in a network on an integrated circuit is provided, the network comprising a router unit, the router unit comprising a first input port, a second input port and an output port, wherein the router unit receives at least one first packet via the first input port, and wherein the router unit receives at least one second packet via the second input port, the router unit arbitrating between the first packet and the second packet, characterized in that the step of arbitrating is performed using a first label and a second label, the first label being attached to the first packet, and the second label being attached to the second packet. This method relies on the perception that the arbitration performed by a router should be based on connection arbitration instead of input port arbitration.

Abstract: The present invention relates to an optical scanning probe assembly for microscopic guide optic scanning and inspection of tissues suitable for application in, e.g. in vivo medical inspection and biopsy. The assembly comprises an outer housing (3) comprising: i) a spring element for a scanning motor, the spring element formed as a hollow tube (5) adapted to receive an optical guide, the hollow tube having mechanical stiffness larger than the optical guide to be received, ii) a lens system (7) and iii) N means for deflecting (6) the distal end of the hollow tube in directions transverse to the longitudinal extension of the hollow tube, so as to form an optical scan pattern. The optical assembly is particularly advantageous as it increases the freedom to optimize the optical and mechanical performance of the system which is defined respectively by the optical guide and by the hollow tube. The probe can be used in resonant and non-resonant scanning modes.

Abstract: The present invention refers to the field of cardiac electrophysiology (EP) and, more specifically, to image-guided radio frequency ablation and pacemaker placement procedures. For those procedures, it is proposed to display the overlaid 2D navigation motions of an interventional tool intraoperatively obtained from the same projection angle for tracking navigation motions of an interventional tool during an image-guided intervention procedure while being navigated through a patient's bifurcated coronary vessel or cardiac chambers anatomy in order to guide e.g. a cardiovascular catheter to a target structure or lesion in a cardiac vessel segment of the patient's coronary venous tree or to a region of interest within the myocard. In such a way, a dynamically enriched 2D reconstruction of the patient's anatomy is obtained while moving the interventional instrument.

Abstract: In an ultrasound imaging system (UIS), an ultrasound scanning assembly (USC) provides volume data (VD) resulting from a three-dimensional scan of a body (BDY). A feature extractor (FEX) searches for a best match between the volume data (VD) and a geometrical model (GM) of an anatomical entity. The geometrical model (GM) comprises respective segments representing respective anatomic features. Accordingly, the feature extractor (FEX) provides an anatomy-related description (ARD) of the volume data (VD), which identifies respective geometrical locations of respective anatomic features in the volume data (VD). In a preferred embodiment, a slice generator (SLG) generates slices (SX) from the volume data (VD) based on the anatomy-related description (ARD) of the volume data (VD).
