Abstract: Some embodiments are directed to a system (100) for selectively disclosing attributes of a record. An issuer device (110) generates a digital signature on a message comprising the attributes and a secret record identifier. The record, secret record identifier, and signatures are provided to a selector device. The selector device (111) selectively discloses attributes of the record to a receiver device (112), proving authenticity by means of a zero-knowledge proof of knowledge of the signature on the attributes. The receiver device (112) verifies the proof with respect to the public key of the issuer and the received attributes.

Abstract: A device is arranged for encrypting input data and protecting integrity of the input data and associated data. An encryption processor has a first hash unit arranged to compute an integrity value based on the input data, a second hash unit arranged to compute an initialization vector based on the integrity value and associated data, producing an initialization vector that is different from the integrity value. At least one of the hash units may be a keyed hash unit. An encryption unit is arranged for encrypting the input data to generate encrypted data using the initialization vector and an encryption key. As the initialization vector depends on both the integrity value and the associated data, any change therein will result in failure of the decryption and decrypted data that are substantially different from the original input data.

Abstract: A method for calibrating at least one of the six-degrees-of-freedom of all or part of cameras in a formation positioned for scene capturing, the method comprising a step of initial calibration before the scene capturing. The step comprises creating a reference video frame which comprises a reference image of a stationary reference object. During scene capturing the method further comprises a step of further calibration wherein the position of the reference image of the stationary reference object within a captured scene video frame is compared to the position of the reference image of the stationary reference object within the reference video frame, and a step adapting the at least one of the six-degrees-of-freedom of a multiple cameras of the formation if needed in order to get an improved scene capturing after the further calibration.

Abstract: The invention provides for a method for switching between fields of view of an ultrasound probe. The method begins by obtaining an anatomical model representing a region of interest of a subject and establishing a first field of view relative to an ultrasonic probe, wherein the first field of view comprises an initial portion of the region of interest. Ultrasound data is then obtained from the first field of view by way of the ultrasonic probe and a first anatomical feature is identified within the first field of view based on the ultrasound data. A location in digital space of the first field of view relative to the anatomical model is determined based on the first anatomical feature. A second field of view is then established based on the anatomical model and the first field of view, wherein the first field of view functions as a reference field of view. The field of view is then switched from the first field of view to the second field of view.

Abstract: An ultrasonic diagnostic imaging system acquires different kinds of pilot images showing different characteristics of a region of a body where shearwave measurements are performed. The pilot images are analyzed by a push pulse locator to adaptively generate push pulses at locations in the body which minimize or avoid shearwave travel through blood vessels, through regions of stiffness inhomogeneities in the body, or at times when shearwaves are adversely affected by tissue motion.

Abstract: Techniques are described herein for incorporating fall prevention into a personalized activity plan. In various embodiments, a baseline risk of fall for a user may be estimated (302) based on baseline sensor signal(s) (203, 205, 207). Based on a prediction model (215) (which may/may not be associated with the user) and the baseline risk of fall, respective risks of falls associated with various candidate activities may be predicted (304), and then candidate activities may be determined or selected (306) based on the predicted respective risks of falls. Output indicative of the determined candidate activities may be provided (308) to the user, who may provide input (310) identifying one or more of the determined candidate activities as an exercise conducted or to be conducted by the user. Based on the exercise sensor signal(s), a subsequent risk of fall for the user may be estimated (312) and used to update (314) the prediction model.

One or more stiffening elements (RD) are arranged inside the first material (PLM), wherein the stiffening element(s) (RD) is formed by a material having a higher axial stiffness than the filling material. A braiding structure (BR) encircles all of: the filling material (PLM), the lumen (LM), and the stiffening element(s) (RD). Such guidewire can be designed with a circular symmetric bending behavior, and is thus suitable as an interventional medical device, e.g. for endovascular procedures, and still it can provide optical shape sensing properties.
