A two-dimensional image pickup device picks up an image of an image pickup target specimen on a stage. The focusing device changes a distance between the objective lens and the stage. A control unit acquires a specific parameter that is used for picking up an image of the image pickup target specimen and selected according to a type of the image pickup target specimen from among a plurality of parameters, each of which is used for picking up an image of each of a plurality of types of specimens. The control unit controls the stage, the two-dimensional image pickup device, and the focusing device on the basis of the specific parameter to acquire an image of the image pickup target specimen in each of a plurality of planes at different heights from the stage at each of a plurality of positions in a plane parallel to the stage.

Embodiments described herein provide systems and methods for secure and efficient user authentication across a variety of computing devices, such as desktops, laptops, smartphones, and tablets across operating systems such as Windows, MacOS, iOS, Android, and iPadOS. The system incorporates an authenticator application configured to communicate with internal or external user identifier scanners, such as RFID/NFC readers, fingerprint scanners, facial recognition cameras, and QR/Barcode scanners, using transport protocols like USB, BLE, or NFC. The authenticator application serves as a third-party passkey provider by interfacing with platform WebAuthn APIs, enabling WebAuthn-based authentication for native applications, browsers, and services, or alternatively as a browser extension, intercepting WebAuthn API calls directly within a browser environment. An authentication server, accessible over a network, verifies user identities by mapping unique identifiers to stored authenticators and requesting additional authentication factors as needed, such as a security PIN. Upon successful authentication, the server transmits passkeys and a session token to the authenticator application, enabling it to handle further authentication requests locally. The system supports advanced session management for shared device environments, allowing configurable passkey storage with options for one-time, time-based, or shift-based expiration, automatically clearing passkeys upon session completion. This design delivers a versatile, secure, and seamless authentication experience across diverse user environments.

A lifting-and-lowering assembly includes a mounting seat (135), a distance sensing module (12), and a drive control module (13), and the distance sensing module is liftably and lowerably arranged at the mounting base. The distance sensing module includes a sensing body (121) and a movable body (122) that is movably connected to the sensing body, and the movable body has a first triggering structure (1221), and the sensing body has a protective switch (1222) located in a movement path of the first triggering structure. The drive control module is assembled on the mounting seat and includes a control main board, a drive motor (131), and an adapting member (133) that is in transmission connection to the drive motor.

The disclosure provides a method and a device for wireless communication. A first signaling is received, the first signaling including a first identifier and a second identifier; and a first signal is transmitted; wherein the first signaling is used for determining a first time-frequency resource set and a second time-frequency resource set, the first time-frequency resource set and the second time-frequency resource set are associated to the first identifier and the second identifier respectively, the first time-frequency resource set and the second time-frequency resource set are both used for random access. Through reasonably associating the second identifier to the second time-frequency resources in K1 cells, with the first node transmitting K2 candidate cells to facilitate random access, the disclosure improves the rate of successful access.
