Abstract: Air cavity and ceramic waveguide resonator mixed filter solutions are disclosed. According to one aspect, a combined filter assembly includes an air cavity filter coupled to a ceramic waveguide (CWG) filter. The CWG filter exhibits a wall that presses against a rigid plate. Between the rigid plate and a wall of the air cavity filter is a compressible conductive gasket that is compressed between the wall of the air cavity filter and the rigid plate. The air cavity filter and the CWG filter are secured to a support base. The CWG filter is secured to the support base by flexible clamps that allow for thermal expansion of the CWG filter. The flexible clamps are secured to the support base by screws. The support base exhibits surfaces or walls that receive and anchor the screws.

Abstract: The present disclosure provides a graphical user interface (GUI) arranged to convey information related to the IVUS images and stent expansion to a user. The GUIs can be generated to include a longitudinal depiction of the vessel and lumen borders as well as a deployed stent. A slider to navigate along the longitudinal axis of the vessel is provided where a stent expansion ratio is dynamically updated based on the slider location.

Abstract: A lattice-based proxy signature method, apparatus and device, a lattice-based proxy signature verification method, apparatus and device, and a storage medium. Polynomials are randomly selected in rings to calculate public and private keys of nodes, and the magnitudes of proxy public and private keys are the same as the magnitudes of public and private keys of an original signer. Therefore, compared with existing proxy signature schemes, the present application has smaller lengths of public and private keys and higher storage efficiency. Proxy signature information generated in the present application shows a signature of the original signer and also shows a signature of a proxy signer. Once a proxy signature is created, the proxy signature cannot be repudiated by the proxy signer, and has strong non-repudiation and strong unforgeability. The proxy signature method has the advantage of resisting quantum computer attack.

Abstract: Techniques and apparatuses are described that implement a hearable with on-head detection using a single optical sensor. The hearable determines on-head detection based on a distance measured by the single optical sensor being less than a distance limit associated with on-head detection. A shape of the hearable's housing causes the hearable to have at least one orientation while at static equilibrium on a flat surface. This orientation causes the flat surface to be within the field-of-view of the optical sensor and causes a distance between the flat surface and the optical sensor to be greater than the distance limit associated with on-head detection. In this way, false positives associated with on-head detection can be mitigated without adding additional sensors (e.g., another infrared sensor, another proximity sensor, or a motion sensor) and without utilizing more complex optical sensors that determine additional information about the object, such as material composition.
