| 20100284583 | READ-OUT METHOD AND APPARATUS - A read-out method for a diagnostic point-of-care assay device, the device including a read-out substrate having at least one response area capable of producing a coloured indication of a response, the response area including a marker at least one marker whose colour changes in response to binding of an analyte thereto and which is used for indication of response. The method includes registering an image of the response area; calculating a colour saturation value S for the image using at least two distinct wavelengths; using the S-value for determining a result of the assay.

| 20100214929 | METHOD AND APPARATUS FOR COMMUNICATION DEVICE CONFIGURATION - A User Equipment UE sends a PDP context activation request with an invalid APN to an SGSN. When detecting an invalid APN the SGSN creates a PDP context activation request towards a GGSN and inserts a default APN. The GGSN detects the default APN and sends a RADIUS Accounting request message to a Device Management System DMS. The DMS initiates a device management configuration flow towards the UE using IP over the existing PDP context or an SMS bearer and responds with a RADIUS Accounting response message to the GGSN. When the RADIUS Accounting response message is received the GGSN will initiate a successful Create PDP context response towards the SGSN causing a successful PDP Context Activation Response towards the UE. An advantage of the invention is that it can detect devices having no GPRS configuration and devices having a faulty GPRS configuration. | 08-26-2010 |

| 20090304250 | Animation for Conveying Spatial Relationships in Three-Dimensional Medical Imaging - Spatial relationships are conveyed in three-dimensional ultrasound imaging. To transition a volume rendering from one view to another view, the transition is animated, showing rotation. For example, the user examines one diagnostic view, but decides to examine another diagnostic view. Upon selection of the other diagnostic view, the volume rendered image appears to rotate. The rotation from one view to another shows the spatial relationship between the views. The user may then examine the static volume rendering at the desired view with an appreciation of the relationship with the previously examined static view. | 12-10-2009 |
| 20090306503 | ADAPTIVE VOLUME RENDERING FOR ULTRASOUND COLOR FLOW DIAGNOSTIC IMAGING - Adaptive volume rendering is provided for medical diagnostic ultrasound. The opacity of B-mode data is set relative to the opacity of Doppler data. The opacities for the different types of data are set as a function of ray depth. For example, the opacity of B-mode data near a tissue border is set to be more opaque than for tissue away from the border, and the opacity for flow data near a flow border is set to be less opaque than for flow away from the border. An image is rendered using a rendering parameter set as a function of ray depth, B-mode information and Doppler information. Other processes for enhancing and/or using rendering may be used. | 12-10-2009 |

| 20080260271 | Method for Reducing the Amount of Data to be Processed in a Visualization Pipeline - A method for reducing an amount of data to be processed in a visualization pipeline. The visualization pipeline includes data capture, data compression, data storage, data decompression, and data rendering including the use of a transfer function. The data is divided into blocks in the compression and the reduction is achieved by adaptively selecting a level-of-detail for each block in the step of decompression utilizing a significance measure based on the transfer function. | 10-23-2008 |
| 20110317893 | IMAGE DATA SET COMPRESSION BASED ON VIEWING PARAMETERS FOR STORING MEDICAL IMAGE DATA FROM MULTIDIMENSIONAL DATA SETS, RELATED SYSTEMS, METHODS AND COMPUTER PRODUCTS - Methods for electronically compressing data from a multidimensional medical data set for long-term storage includes: (a) generating a first medical image from a patient multi-dimensional medical image data set in a short-term storage format; and (b) compressing the patient medical image data set into a long-term storage format using at least one viewing parameter. | 12-29-2011 |
