20150085893 | PRISM BEAM EXPANDER ADJUSTMENT APPARATUS AND METHOD FOR ADJUSTING THE SAME - An apparatus and method for adjusting prism beam expander. The prism beam expander adjustment apparatus has a light source, a baseplate, a precise rotary stage, support columns, a two-dimensional slide stage, the first 90-degree bellcrank lever, an indication light source, the second 90-degree bellcrank lever, an optical filter, a photodetector, a computer, and an assembly platform. Incidence angles of all prisms of a prism beam expander can be precisely demarcated and designed beam magnification is obtained with the preferred adjustment methods. The parallel of the prisms can be guaranteed by monitoring the pitching of the prisms in the adjustment process. As a result, the linewidth narrowing and cavity losses decreasing can be improved by application of the fixed prism beam expander. | 03-26-2015 |

20140195986 | CONTACTLESS REMOTE CONTROL SYSTEM AND METHOD FOR MEDICAL DEVICES - The present invention provides a contactless remote control system enabling an operator to operate one or more medical devices in a contactless way, said remote control system comprising a display device for displaying a Graphic User Interface GUI regarding the one or more medical devices; a tracking device for tracking the motion information of the operator; a control device for (1) interpreting the motion information of the operator into operation information relating to the movement trajectory of a cursor in the GUI or the confirmation of the selection of an item in the GUI where the cursor locates, and for (2) operating the GUI in accordance with the operation information so as to generate control commands for the one or more medical devices; and an output device for outputting the control commands to the one or more medical devices. This system of the present invention enables the operator to operate and control the medical device in a more convenient way, and causes the degree of user satisfaction to be improved. | 07-10-2014 |
20140362114 | METHOD AND APPARATUS FOR NEEDLE VISUALIZATION ENHANCEMENT IN ULTRASOUND IMAGES - The present invention provides a method and an apparatus for needle visualization enhancement in ultrasound (US) imaging and an US imaging system. The apparatus comprises: a Radon transform (RT) unit adapted to perform RT on a sequence of frames to detect line features in the frames, a frame comprising US radio-frequency (RF) data obtained during monitoring the insertion of a needle into a subject or an US image reconstructed from the RF data; a false needle feature removing unit adapted to remove line features which remain substantially stationary among the frames as false needles while locating a line feature which extends among the frames as the needle; and an overlaying unit adapted to overlay the location of the line feature as the needle on an US image of a frame to produce an enhanced image to be displayed. | 12-11-2014 |
20140378796 | SYSTEM AND METHOD FOR NEEDLE NAVITATION USING PA EFFECT IN US IMAGING - The present invention provides a monitoring system, which comprises a novel needle, and an optical signal generating device, wherein at least one optical signal output of the optical signal generating device is coupled to the optical core of the needle, and it further comprises an ultrasound (US) transducer,and a processor adapted to direct the US transducer to transmit an US signal into a region of a subject in which the needle is moving and receive an US signal reflected in the region in response to the transmitted US signal in a US measurement sub-cycle of a measurement cycle, and to direct the optical signal providing device to transmit an optical signal having a unique wavelength from the dome of the needle into an area of the region and direct the US transducer to receive a photo-acoustic (PA) signal induced in the area in response to the optical signal in each of at least one PA measurement sub-cycle of the measurement cycle, and reconstruct an US image from the US signal received in the US measurement sub-cycle. | 12-25-2014 |

20150312376 | SYSTEM AND METHOD FOR SUPPORTING A BYPASS-DOMAIN MODEL FOR ACROSS-DOMAIN MESSAGING IN A TRANSACTIONAL MIDDLEWARE MACHINE ENVIRONMENT - A system and method can support across-domain messaging in a transactional middleware machine environment. A transaction domain can import one or more services from a remote transaction domain, wherein said one or more services are registered in a service table that is associated with the transaction domain. Furthermore, a client in the transaction domain can find from the service table a remote server in the remote transaction domain that provides said one or more services, and send a message directly to the remote server to invoke said one or more services by passing one or more domain gateway servers in both the transaction domain and the remote transaction domain. | 10-29-2015 |
20150312377 | SYSTEM AND METHOD FOR UPDATING SERVICE INFORMATION FOR ACROSS-DOMAIN MESSAGING IN A TRANSACTIONAL MIDDLEWARE MACHINE ENVIRONMENT - A system and method can support across-domain messaging in a transactional middleware machine environment. A gateway server in a transaction domain operates to provide a notification of an update in one or more services to one or more gateway servers in one or more remote transaction domains. Furthermore, the gateway server can receive an inquiry for said one or more services from a remote transaction domain, and send a response to a gateway server in the remote transaction domain, wherein the response contains information that allows a client in said remote transaction domain to invoke said one or more services. | 10-29-2015 |
20150312378 | SYSTEM AND METHOD FOR SUPPORTING A PROXY MODEL FOR ACROSS-DOMAIN MESSAGING IN A TRANSACTIONAL MIDDLEWARE MACHINE ENVIRONMENT - A system and method can support across-domain messaging in a transactional middleware machine environment. Using a proxy model, a first transaction domain can export one or more services to a second transaction domain, wherein said one or more services are imported from a third transaction domain. Furthermore, a first gateway server in the transaction domain can receive a request from a client in the second transaction domain to invoke said one or more services in the third transaction domain, and can route the request to a server in the third transaction domain that provides said one or more services. | 10-29-2015 |
