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 ultrasonic diagnostic imaging system has a user control by which a user positions the user's selection of a heart chamber border in relation to two myocardial boundaries identified by a deformable heart model. The user's border is positioned by a single degree of freedom control which positions the border as a function of a single user-determined value. This overcomes the vagaries of machine-drawn borders and their mixed acceptance by clinicians, who can now create repeatably-drawn borders and exchange the control value for use by others to obtain the same results.

Abstract: The present invention relates to a method for detecting slippage when gripping an object with a gripper, in which use is made of at least one acceleration sensor (5) on a gripping surface (3) of the gripper (1), a sensor signal from the acceleration sensor (5) is captured during the gripping process and filtered in order to obtain a filtered sensor signal in a first frequency range, and the filtered sensor signal or a value derived therefrom is compared with a threshold value (SW1, SW2) which, when exceeded, constitutes an indication of slippage of the object.

Abstract: The invention relates to a valve. A valve seat (2) encloses a fluid passage (20) for passage of a fluid from a fluid chamber (3). A holding element (4) exerts a holding force on a valve body (1), the holding force acting in a direction towards a valve seat (2). In the event that the fluid acts on an effective surface (10) of the valve body (1) with a force or a pressure above a limit value, the valve body (1) moves away from the valve seat (2). In the event that the fluid acts on an effective surface (40) of the holding element (4) with a force or a pressure above a limit value, the holding force acting on the valve body (1) decreases. In doing so, the fluid acts on the holding element (4) more strongly and/or earlier than on the valve body (1).

Abstract: Provided is a method (200) for generating a combined anatomical model of a heart. The method comprises receiving (220) a non-contrast agent-enhanced ultrasound image of a left ventricular region of the heart and receiving (240) a contrast agent-enhanced ultrasound image of the left ventricular region of the heart. Image registration (260) is performed on the respective non-contrast agent-enhanced and contrast agent-enhanced ultrasound images, such that the respective images are aligned. Combined segmentation (270) of the aligned non-contrast agent-enhanced and contrast agent-enhanced ultrasound images is then carried out to generate the combined anatomical model. The combined segmentation (270) uses features of both of the aligned non-contrast agent-enhanced and contrast agent-enhanced ultrasound images as target points. Further provided is a processor arrangement adapted to implement the method and an ultrasound system comprising the processor arrangement.

Abstract: A cargo reversed tricycle apparatus and method providing an open front, allowing the encompassing of cargo and a low center of weight when carrying, allowing more options in loading, transporting, and unloading and improved stability and maneuverability. A front-open frame provides cargo space between the front wheels, and allows for a variety of ways to load, transport, and unload the cargo. A dual-crossed-drag-link steering arrangement is provided, where a drag-link driver linked to the handlebar pushes and pulls shaped link rods, which transfer the forces through pivot links on turning bars on the two front-wheel units, which thereby turn in the intended direction.

Abstract: A valve suitable for an air spring includes a housing body with a central longitudinal axis and channel. The housing body has a first valve opening fluidically connectable to an air spring volume, a second valve opening fluidically connectable to an air supply, which is fluidically connectable to an air spring volume, and a second valve opening which is fluidically connectable to an air supply. Each valve opening is fluidically connected or selectively connectable to the channel. A pressure limiter is provided to limit the pressure flowing out of the second valve opening, the pressure limiter including a third sealing agent and a second sealing agent associated with the second valve opening and selectively closing an opening, wherein pressurization of at least the third sealing agent displaces the second sealing agent due to the forced coupling such that it closes the corresponding opening or reduces the effective opening cross-section.

Abstract: Slice alignment approaches are described for short axis cardiac magnetic resonance cine slice stacks, which do not require additional scans, such as long axis scans or full 3D scans, and which are able to deal with cardiac structures having complex shapes. Both approaches do not need contours to follow a quadratic curvature function, and are well suitable for the purpose of obtaining a segmentation of a cardiac structure using a deformable surface model. Namely, such a deformable surface model is unable, but also not desired, to fully adapt to the ‘zig-zag’-shaped pattern in the boundary of the cardiac structure due to the slice misalignment. Having removed or reduced the misalignment between image slices, such a deformable surface model may better adapt to the cardiac structure in the image data and 10 thereby provide a better segmentation of the cardiac structure.

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.
