Abstract: An entirely or partially implantable medical product with a negatively charged surface for repulsing bacteria has a superficially bonded substance with a permanently negative excess charge, which substance is inert against cells of the human body and the bacteria contained therein.

Abstract: A completely or partially implantable medical device, the surface of which has attached to it a substance having a permanent negative charge excess, to which is in turn attached an antimicrobial substance. This imparts antimicrobial properties and at the same time repels the cellular constituents of killed bacteria.

Abstract: A gastroenterological medical device, particularly a stent for the gall or pancreatic duct, has a substantially tubular, intrinsically stable carrier that is provided with a spacer layer that is attached to the carrier surface, and a layer of an electronegative glycosaminoglycan that is attached to the spacer layer.

Abstract: The present invention relates to a method and imaging system to compensate for patient movements when recording a series of medical images, in which a number of images of an area of a patient to be examined are recorded at intervals and are related to one another, especially for movement compensation in Digital Subtraction Angiography (DSA) or roadmapping (RDMP) in the abdominal area. A plurality of breath-triggered mask images is recorded during a breathing cycle. Frilling images are recorded with the same triggering and mask images and filling images which are recorded for the same breathing states are subtracted from each other in realtime and the difference recordings are displayed in realtime.

Abstract: A presentation system and method for presenting information to an audience within a space hat includes a plurality of mobile projectors and a master presentation unit that can be moved into a presentation space and associated where the projectors and master unit are quickly linkable via a network and where the master unit expedites the system configuration process to allow the system user to manipulate images presented by all of the projectors.

Abstract: A presentation system for presenting information to an audience within a space, the system comprising a control interface, a master presentation unit including a flat panel display screen and a processor, the screen including a master space and a slave presentation assembly including a slave presentation surface and a first projector for projecting images on the slave presentation surface, the master unit processor linkable to the interface to receive commands therefrom, the processor programmed to monitor for a command from the interface to flip an image from the master space to the slave space and, when a command to flip an image is received, causing the image from the master space to be presented in the slave space.

Abstract: The optical fiber holder of the coupling device has a top, a bottom, and narrow side faces between the top and the bottom. Intermediate faces are formed at the transitions between the narrow side faces and the top and the bottom. A receptacle into which the holder is inserted axially has internal contact areas which are in contact with the intermediate faces without play.

Abstract: The present invention includes interactive communication systems that incorporate several beneficial embodiments including an interactive tray system, an electronic presentation messaging system, an interactive podium, and a key drive system. The interactive tray system enables a single, transferable interactive unit to be fastened to a communication medium, turning into a fully interactive medium. The electronic presentation messaging system enables the e-mailing of presentations and notes to and from components of the interactive communication system. The interactive podium increases conventional podium mobility, enabling both the presenter, and podium, to move and be moved about the room without attention to wired connections.

Abstract: A presentation system for presenting information to an audience within a space, the system comprising a control interface, a master presentation unit including a flat panel display screen and a processor, the screen including a master space and a slave presentation assembly including a slave presentation surface and a first projector for projecting images on the slave presentation surface, the master unit processor linkable to the interface to receive commands therefrom, the processor programmed to monitor for a command from the interface to flip an image from the master space to the slave space and, when a command to flip an image is received, causing the image from the master space to be presented in the slave space.

Abstract: A presentation method and system for presenting information to an audience within a space that mimics a flip chart assembly, the system including a control interface, a communication network and a master presentation unit including a processor and a master display screen, the master screen juxtaposed within the space so as to be viewable by the audience within the space, the processor operable to transmit an image displayed on the master screen over the network upon user command and a slave presentation unit including a slave presenter operable to receive and present an image to the audience within the space that is transmitted by the master unit to the slave unit over the network such that the master unit can be used to create a new image while the first image is simultaneously presented.

Abstract: An interactive display system is provided including a support frame having a vertical positioning element that counterbalances the weight of an attached interactive display, for example a touch-sensitive display. The support frame optionally includes a power supply increasing the range of mobility of the interactive display system by eliminating the need for power cord and power outlet connections. One exemplary support frame for an interactive display includes a base element, at least one support extending vertically from the base element, and a positioning element housed within the at least one support. The positioning element counterbalances the weight of the interactive display allowing vertical repositioning of the interactive display with a force of less than about 25 pounds.

Abstract: A remote controllable electronic whiteboard system and method of operating the remote controllable electronic whiteboard system are provided. An exemplary remote controllable electronic whiteboard system includes an electronic whiteboard in communication with a remote control device. Methods of operating the electronic whiteboard system including the use of a remote control device are also provided.

Abstract: A urological implant, in particular a vascular wall support for the urinary tract, is provided with a substantially tubular, inherently stable carrier, a spacer film bonded to the carrier surface, and an inhibitor film of a glycosamino glycan bonded to the spacer film.

Abstract: The power (performance) of an electric arc welder is controlled in dependence upon the changes in the level of the pool of weldment with respect to the level of the adjoining surfaces of the workpiece. The level of the pool of weldment is detected by measuring the arc voltage and, in accordance with the invention, the distance between the end of the fusible electrode and the level of the workpiece upper surfaces adjoining the pool is maintained constant.

Abstract: A process for shielding molten metal of a casting stream in a casting apparatus from oxidation by the ambient atmosphere which comprises enclosing the casting stream in an atmosphere which consists essentially of a mixture of an inert gas such as nitrogen as a carrier and a reactive gas, such as a hydrocarbon, capable of reacting with oxygen in the melt. The gas atmosphere preferably consists of a mixture containing 5 to 20% by volume of the reducing gas, namely, the hydrocarbon, the balance being the carrier gas namely nitrogen. Any conventional technique can be used to ensure that the gas mixture covers the casting stream.

Abstract: A casting apparatus in which a stream of molten metal is cast into a casting mold (e.g., an ingot mold) is provided along the stream with a porous refractory body to which supplied droplets of the metal do not adhere. A protective gas, usually nitrogen, is forced through the body to form a curtain or shield around the stream of the melt.
