Abstract:
In order to improve depth perception for an image displayed during a laparoscopic surgery, a representation of a shadow of a tool included in the image and used in the laparoscopic surgery is identified and introduced into the image. A processor augments a three-dimensional (3D) model including a 3D representation of a surface of an object included in the image, and a representation of the tool by introducing a virtual light source into the 3D model to generate a virtual shadow within the 3D model. The processor subtracts the representation of the shadow out of the augmented 3D model and superimposes the representation of the shadow on the image to be displayed during the laparoscopic surgery.
Abstract:
A pipetting device having a modular pipetting unit including a pipetting tip for pipetting of fluid samples and a pump conduit for transferring a negative or positive pressure to the pipetting tip is disclosed. The pipetting tip and a portion of the pump conduit adjoining the pipetting tip mutually define a fluid sample conduit for receiving the fluid samples. The modular pipetting unit is detachably attached to an automated positioning device for positioning the modular pipetting unit. A system and method for pipetting of fluid samples using such a pipetting device are also disclosed wherein pipetting of the fluid samples is performed in such a manner that each pipetted fluid sample volume is smaller than a volume of the fluid sample conduit.
Abstract:
A method and apparatus for delivery of a solid particulate fuel to a heating system. The present invention provides a lock-up transport system to deliver particles of solid fuel in a downstream direction while maintaining the position of the particles relative to each other. The lock-up transport system provides a linear mass flow of fuel through the gasification stages of the fuel.
Abstract:
The invention relates to a positioning device (1) for an X-ray detector (11) or an X-ray source (23), comprising an arched arm (15), inside of which the X-ray detector (11) or the X-ray source (23) can be mounted in a manner that enables it to be displaced in the direction of the arch, and comprising a base (9), inside of which the arched arm(15) is mounted in a manner that enables it to be displaced in the direction of the arch. Either the X-ray detector (11) is mounted in the positioning device (1) and the X-ray source (23) is placed separately therfrom or, conversely, the X-ray source (23) is mounted in the positioning device (1) and the X-ray detector (11) is placed separately there from.
Abstract:
An arrangement and a method for the production of photomasks in which at least one defect control system is connected to at least one repair system by a stationary data connection or online connection, and the defect control system and repair system are connected to one another by data in such a way that the results obtained on one of the systems are immediately available to the other system for further processing. The defect control system conveys detected defects to the repair system via a data connection for data exchange. An AIMS system is advantageously provided as defect control system and an electron beam system is advantageously provided for defect control.
Abstract:
A fiber optic transmission cable fiber protector includes a splice tube positioned over the ends of a pair of fiber optic cables having an outer capillary tube containing at least one optical fiber within an inner capillary tube. The optical fiber protector includes a pair of optical fiber strain relief mechanism positioned near the ends of the optical fibers; the strain relief mechanisms are captured within a heat sink tube that is inserted into each end of the outer capillary tubes. The splice tube is welded to the outer capillary tubes. Heat generated by the welding process dissipated by the heat sink and gases generated during the welding process are vented through a hole in the outer capillary tube into the optical fiber splice area. In an alternate embodiment a weld coupling is welded to each end of the splice tube and is further welded to the outer capillary tubes. A sealing mechanism is positioned on the inner capillary tubes within the outer capillary tubes forming a seal therebetween. A splice protection sleeve is positioned over the optical fiber splice area to protect the splice during assembly of the protector. In an alternative embodiment an optical fiber protector assembly includes a carrier tube disposed onto the inner capillary tube and an optical fiber strain relief mechanism positioned within the carrier tube near the end of the optical fiber capturing the fiber therein in a strain relieved condition.
Abstract:
The invention relates to a transversal electrooptical modulator (10) which can be controlled by means of an electric amplifier, comprising at least two elements for modulating (11) the light wave of a laser beam, and can preferably be used for projection of TV images. The invention is characterized in that the modulator elements are arranged behind each other in relation to the laser beam, that a focusing device (14) is arranged both in front of and behind each modulator element, that an electric amplifier output (22, 23) is associated with each modulator element and that all electric amplifier (A) inputs (24, 25) are connected to the same control line (26) as the control signal.
Abstract:
A measuring arrangement is calibrated for determining rotational positions of a rotary device that has a first part and a second part which can be rotated relative to the first part about a rotational axis. Rotational positions of the first part relative to the second part and/or rotational positions of the second part relative to the first part are detected using a plurality of sensors distributed about the rotational axis. A respective measurement signal corresponding to each detected rotational position is generated such that redundant information on the rotational positions of the first part and the second part relative to each other is provided. The redundant information on the rotational position(s) are analyzed such that effects of a translational movement of the first and the second part relative to each other are corrected, the translational movement running transverse to the extension of the rotational axis.
Abstract:
A method for providing a service transaction for a mobile device of a user at a point of sale (POS) of a supplier, whereinthe method comprises the steps of sending (S2) by said mobile device an individual supplier code (SC) read (S1) by said mobile device from a supplier tag located at the point of sale (POS) of said supplier to a server of a service provider; returning (S5) a service valid message (SVM) by said server of said service provider to the mobile device if the supplier code (SC) belongs to a registered supplier of the respective service; and performing (S6) a service transaction of the respective service at the point of sale (POS) of the registered supplier in response to the service valid message (SVM) received by the mobile device.
