  • Patent number: 12010467
    Abstract: A method (and system) is provided obtaining an adapted calibration transformation for whole slide imaging, wherein the adapted calibration transformation is for outputting the color of an empty area of the slide in a whole slide image, WSI, as a desired color. The method comprises first receiving a color target WSI in a device-dependent color space, wherein the color target WSI is a WSI of a color target from a scanner represented in the device-dependent color space. The color target contains at least a white patch and three (near) primary color patches. A calibration transformation is obtained for transforming the device-dependent color space to a device-independent color space. A chromatic adaptation transformation is derived using the color of the white patch in the device-dependent color space, the color of the empty (glass) area in the device-independent color space and the desired empty (glass) color in the target color space.

  • Patent number: 12010243
    Abstract: This application relates to devices and methods of authenticating messages exchanged over a network between a transmitter and a receiver. The transmitter generates a truncated MAC code by selecting predetermined bits from a message authentication code (MAC) computed over a concatenation of a part of the message with a part of a previously transmitted message. The transmitter appends the truncated MAC code to the message for transmission. The receiver receives a previously transmitted message, the currently transmitted message, and the truncated MAC code, and generates an expected truncated MAC code by selecting predetermined bits from a message authentication code (MAC) computed over a concatenation of the part of the message with the previously transmitted message. The receiver authenticates the message and the previously transmitted message if the truncated MAC code as received is identical to the expected truncated MAC code.

  • Patent number: 12007291
    Abstract: A wireless pressure sensing unit (20) comprises a membrane (25) forming an outer wall portion of a cavity and two permanent magnets (26,28) inside the cavity. One magnet is coupled to the membrane, and at least one magnet is free to oscillate with a rotational movement. At least one is free to oscillate with a rotational movement. The oscillation takes place at a resonance frequency, which is a function of the sensed pressure, which pressure influences the spacing between the two permanent magnets. This oscillation frequency can be sensed remotely by measuring a magnetic field altered by the oscillation. The wireless pressure sensing unit may be provided on a catheter (21) or guidewire.

  • Patent number: 12008750
    Abstract: Currently, there is interest in applying machine learning techniques to analyse digital pathology images automatically. Machine learning techniques often rely on training with a ground-truth image input. The quality and amount of training data determines the quality of the detector, as expressed in the rate of true and false positives, and robustness against variations in the appearance of the input images. The present application proposes to obtain image data of the same sample before and after at least one re-staining step (firstly with a structure-revealing stain, and secondly with a bio marker revealing stain). Sections of the first and second image data having a good registration relationship are chosen, along with the probability of detecting a desired candidate object (such as nucleus) and the probability of the bio marker revealing stain being present annotation data suitable for training a machine learning algorithm on the first and/or the second image data is provided.

  • Patent number: 12004908
    Abstract: An ultrasound imaging system transmits two beams in succession in the same beam direction, the waveform of the second beam being a phase inverted form of the first waveform, and each waveform containing first and second major frequency components. Echoes are received from along the beam direction in response to each beam transmission, and are processed by additively and subtractively combining the two echo sequences on a common depth basis. The echo components resulting from this processing extend from high frequencies for good near field resolution to low frequencies for good depth penetration, and include fundamental, harmonic, and sum or difference frequency components. The linear and nonlinear echo signal components may be frequency compounded for speckle reduction.

  • Patent number: 11998668
    Abstract: A connection mechanism (18) for connecting a workpiece (12) to a handle assembly (14) of an oral care device (10). A collet (30) has an axially extending beam (32) and a radially extending protrusion (34). The protrusion has a latching surface (44) that prevents disengagement of the workpiece from the handle assembly when in a locked configuration. A cam feature (40) is configured to convert an axial force exerted on the collet into radial deflection of the beam to transition the connection mechanism to an unlocked configuration in which the latching surface is disengaged from the corresponding surface of the workpiece. The beam is configured to return to the default position after the axial force is released due to strain energy in the beam resulting from the radial deflection.
