Abstract: A system and method for achieving more accurate results when applying an image processing task to a series of medical images of a patient, without significantly increasing processing resource. The proposed system and method is based on receiving a plurality of image sequences of a particular anatomical region, each capturing cyclical movement of an anatomical object. Each image sequence is supplied to a classifier module which employs use of one or more machine learning algorithms to derive at least one score for each image sequence indicative of predicted success or quality of a result of the image processing task if applied to the given image series. This permits an assessment to be made in advance of which of the plurality of image series is most likely to result in the best (e.g. highest quality, or greatest amount of information) results from the image processing task.

Abstract: A system is disclosed for identifying a user based on the classification of user characteristic data. An identity verification system receives a request from a requesting target user for access to an operational context and characteristic data describing actions of the requesting target user. The identity verification system inputs the characteristic data to an identity confidence model to determine an identity confidence value describes a likelihood that an identity of the requesting target user matches an authenticating identity and determines a false match rate and false non-match rate, which represent a performance of the identity confidence model. The identity verification system determines a match probability for the requesting target user by adjusting the identity confidence value based on the determined false match rate and false non-match rate and grants the requesting target user access to the operational context if match probability is greater than the operational security threshold.

Abstract: An electronic device may be provided with an antenna, a receiver, and baseband circuitry coupled to the receiver over a digital interface. The receiver may receive radio-frequency signals using the antenna and may generate digital in-phase and quadrature-phase (I/Q) samples from the radio-frequency signals. The I/Q samples may have a bit width and may be transmitted to the baseband circuitry over the digital interface. The baseband circuitry may evaluate a radio condition of the receiver based on the I/Q samples. The baseband circuitry may adjust the bit width of the I/Q samples based on the radio condition. For example, the baseband circuitry may decrease the bit width when wireless performance metric data falls below a threshold and/or may increase the bit width when the wireless performance metric data exceeds a threshold. This may minimize power consumed by the digital interface without sacrificing wireless performance.

Abstract: A VIN verification system allow an accurate detection of incorrectly entered VIN in an electronic file followed by correction of the incorrectly entered VIN. A server of the VIN verification system verify characters and letters of the VIN in the electronic file to detect data entry and/or transmission errors. The server upon determining that the characters and entered in the VIN are incorrect will then replace the characters and letters with alternate or substitute characters and letters and generate a new VIN in the electronic file. The server will reexamine the new VIN to validate the new VIN, and then transmit the electronic file to another web application for further processing.

Abstract: A method is provided for generating an ultrasound image of an anatomical region having a volume. First image low resolution image data is enhanced by adapting a 3D anatomical model to the image data to generate a second, greater, quantity of ultrasound image data in respect of the anatomical region. The enhanced volumetric information is then displayed. An anatomical model is thus used to complete partial image data thereby increasing the image resolution, so that a high resolution volumetric image can be displayed with a reduced image capture time.

The processor is coupled to the spectral engine, camera and display, and configured with instructions that, when executed, cause the processor to display a live view of the second field of view on the display with a representation of the location of the first field of view superimposed on the displayed live view, an area of interest is detected as wholly occupying the first field of view, and a measurement is made.

Abstract: A method is provided for determining one or more tissue boundaries within ultrasound image data of anatomical region. The method is based on generating two separate images from the same input ultrasound data, acquired in a single acquisition event. One image is generated with contrast enhancement, so that boundaries surrounding a fluid-containing region are especially well visible and, the second image is generated without this enhancement, or with a different enhancement so that boundaries surrounding tissue regions are especially well visible. An image segmentation procedure is then applied which uses a combination of both images as input and uses both to determine the boundaries within the imaged regions.

Abstract: Secure pairing of computing devices, such as a field tool and a battery-powered device (BPD), may include generating by the BPD a challenge message including a randomly-generated challenge, and receiving at the field tool a challenge message from the BPD via a Bluetooth low-energy (BLE) advertisement message. The challenge message can include a randomly-generated challenge and can be issued in a scannable undirected advertising message. The challenge key can be calculated via a secure hash algorithm (SHA) to obtain a response solution. The response solution can be sent by the field tool to the advertising device in response to the challenge message. The response solution can be verified by the BPD using a cryptographic message authentication code such as an HMAC, and the BPD sends a confirmation message to the field tool indicating that the response solution is verified as correct.

Abstract: An ultrasound control unit (10) is for coupling with an ultrasound transducer unit (12). The control unit is adapted to control a drive configuration or setting of the transducers of the transducer unit, each drive setting having a known power consumption level associated with it. The control unit includes a control module (20) adapted to adjust the drive setting from a first setting to a second setting, the second having a lower associated power consumption that the first. The second setting is tested by an analysis module (16), the analysis module adapted to determine a measure of reliability of ultrasound data acquired by the transducer unit, for the purpose of deriving at least one physiological parameter, when configured in the second setting. The second setting is only used if its determined reliability passes a pre-defined reliability condition.
