To support specifying a position of a tissue of interest in a living body. In a past ultrasound examination, a processor generates a reference image including a body mark image and a probe mark, and also registers position information indicating a position of a tissue of interest in a living body. In a current ultrasound examination, the processor generates a second reference image that includes a body mark, a probe mark, and a pointer. The processor determines a display position of the pointer with respect to the probe mark based on the registered position information.

Base station antennas include a cylindrical RF lens and at least one radiating element. The cylindrical RF lenses are hybrid lenses that include both metamaterial focusing elements and dielectric material focusing elements. The RF lenses may comprise a plurality of concentric cylindrical laminae having conductive scattering elements formed thereon and thin dielectric slabs to enhance the performance of the sparsely spaced scattering elements to achieve well defined patterns with low sidelobes and low cross polar discrimination.

An object of the present disclosure is to reduce the number of times of transmitting ultrasound pulses while maintaining Doppler measurement performance for an ultrasound diagnostic apparatus. An intermittent transmission pattern determination method includes obtaining reference measurement information for reference transmission and intermittent measurement information for intermittent transmission, and obtaining error evaluation information representing a difference between the reference measurement information and the intermittent measurement information. The reference measurement information is information indicating a situation in which Doppler measurement information is obtained in a reference transmission operation. The intermittent measurement information is information indicating a situation in which the Doppler measurement information is obtained in an intermittent transmission operation. The reference measurement information and the intermittent measurement information may include a Doppler shift frequency. In addition, the reference measurement information and the intermittent measurement information may include information indicating a high-pass filter characteristic of a wall filter according to the number of received Doppler signal values, and aliasing characteristic information regarding the Doppler shift frequency.

Provided are an ultrasound diagnostic apparatus and a control method of an ultrasound diagnostic apparatus that can easily and accurately select an ultrasound image of a frame suitable for measuring a diameter of a left ventricular outflow tract.The ultrasound diagnostic apparatus that guides a frame suitable for measuring a diameter of a left ventricular outflow tract from ultrasound images of a plurality of frames in which a heart of a subject is imaged includes an image recognition unit that performs image recognition on a local anatomical structure of the heart in each of the plurality of frames, a time-varying waveform generation unit that generates a time-varying waveform of an anatomical structure state based on the local anatomical structure recognized by the image recognition unit, a candidate frame extraction unit that extracts a measurement candidate frame from the plurality of frames using the time-varying waveform, a monitor, and a display controller that displays the measurement candidate frame in a highlighted manner on the monitor.

A storage container comprising a base; a lid pivotably coupled to the base by a hinge and selectively retained in a closed position; a plurality of pockets positioned on one of the base and the lid and having sides recessed with respect to a first direction, each of the pockets defining an open space surrounded at least partially by a wall extending from the base or the lid, at least one angled edge of each wall being oriented at an oblique angle relative to a front surface of the base; a surface formed on the other of the base and the lid; a plurality of projections extending from the surface with respect to the first direction, each of the projections having a projection profile substantially corresponding to an associated one of the pockets, each of the projections being substantially aligned with the associated one of the pockets along the first direction; an edge portion protruding from one of the projections in a plane substantially normal with respect to the first direction, the edge portion oriented at the oblique angle relative to a front surface of the base; a gap formed between the edge portion and the surface; and a sliding member having a blocking surface extending generally parallel to the front surface of the base, the sliding member having a locked position and an unlocked position.

A printing apparatus (10) includes a housing (11), a plurality of printer units (50), and at least one accommodation portion (34) that attachably and detachably accommodates at least one of the plurality of printer units and that is displaceable with respect to the housing.

A cavity phase shifter comprises a first cavity, a first main phase shifter circuit, a first moveable phase shift component, and a first sliding linkage for the first moveable phase shift component mounted within the first cavity; and a second cavity, a second main phase shifter circuit, a second moveable phase shift component, and a second sliding linkage for the second moveable phase shift component mounted within the second cavity. The first and second cavities are arranged side by side in a horizontal direction, and first and second grooves for at least partially exposing the respective first and second sliding linkages are provided on the cavity phase shifter. The first and second grooves are arranged side by side in the horizontal direction, and a dimension of the second groove is different from a dimension of the first groove.

A method is proposed for authenticating a block of data as a block of authentic data. A digital signature is associated with the block of authentic data. According to such method, an electronic device executes:- generating a verification key;- decrypting the signature using the verification key delivering a reference data associated with the block of authentic data; and- comparing the reference data with test data function of the block of data delivering an information representative of the authenticity of the block of data.The verification key is generated from a Root Key using a key ladder.

A device is proposed for authenticating a block of data as a block of authentic data. A memory of the device is populated with a digital signature resulting of an application of one algorithm, hereafter signature algorithm, to the block of authentic data using a shared key, the signature algorithm being one algorithm among the two complementary algorithms of a symmetric-key cryptographic scheme. The device is configured for:- obtaining the shared key;- decrypting the signature using the shared key and the other algorithm than the signature algorithm among the two complementary algorithms of the symmetric-key cryptographic scheme; and- comparing reference data delivered by said decrypting with test data function of the block of data delivering an information representative of the authenticity of the block of data.The device is configured for not allowing the use of the shared key with the signature algorithm.

A lid for a drink container, the lid including: a body including a first side, a second side opposite the first side, and an opening formed through the first side and the second side, the second side configured to removably couple to the drink container, the opening configured to permit fluid to pass therethrough; a slider slidable relative to the body between a closed position, in which the opening is closed, and an open position, in which the opening is open; and a hanger movable relative to the body between a first position, in which the hanger engages the slider to inhibit the slider from moving from the closed position to the open position, and a second position, in which the hanger extends outwardly from the body and is configured to couple the lid to a support.
