摘要:
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.

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.

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.

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. The key drive system replaces the conventional Y-connector of the key drive technology by effectively integrating the key drive in the device, thus only having one connector, and eliminating the need to change connectors from the key drive, to the USB connector, upon software driver loading.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
