Abstract: Systems and methods for an ultrasound scanner with an impact-resistance system are described. In some implementations, the impact-resistance system reduces acceleration components associated with an impact force applied to an enclosure of the ultrasound scanner or directly to an acoustic lens of a transducer array of the ultrasound scanner. The impact-resistance system distributes the acceleration components from the transducer array to the enclosure via couplings with soft and elastic materials. Some of the couplings may be located between the enclosure and elongated members embedded in backing material of the transducer array. Some of the couplings may be located between the enclosure and a flange that extends from the acoustic lens into a channel in the enclosure. Implementing the impact-resistance system described herein improves reliability of the transducer array without sacrificing performance or usability, particularly for ultraportable scanners.

Abstract: The present disclosure relates to resource reservation methods. One example method includes receiving, by a controller, a resource reservation request that is of a communication session and that is sent by a sending device, where the resource reservation request carries resource requirement information, obtaining, by the controller based on the resource reservation request, identification information of a network device through which data transmission of the communication session to be performed between the sending device and a receiving device passes, and a resource index of the network device, sending, by the controller, the resource requirement information and the resource index to the network device based on the identification information, where the resource requirement information and the resource index are used to instruct the network device to configure a resource for the communication session, and sending, by the controller, the identification information and the resource index to the sending device.

Abstract: Embodiments of the disclosure provide a private key generation method and a device. The method includes: receiving, by a first terminal from a second terminal, a first half session key parameter corresponding to the second terminal and an identifier of the second terminal; sending, by the first terminal, the first half session key parameter corresponding to the second terminal and the identifier of the second terminal to an IKMS entity; sending, by the first terminal to the second terminal, the second half session key parameter corresponding to the second terminal and the encrypted private key corresponding to the second terminal that are sent by the IKMS entity, where the second half session key parameter corresponding to the second terminal is used to decrypt the encrypted private key corresponding to the second terminal. This can prevent a private key from being stolen, and prevent communication information between groups from being stolen.

Abstract: An area restricted access system, method, and non-transitory computer-readable storage medium are provided. The system includes an access device and a first service device located in a service area, wherein the access device locates a user device via a first type of wireless signals and obtains a first location parameter. The first service device monitors and locates the user device via a second type of wireless signals and obtains a second location parameter. The area restricted access system generates a modified location parameter based on the first and the second location parameters and determines whether the user device is within or out of the service area based on the modified location parameter. The first service device allows the user device to access the first service device when the user device is within the service area, and forbids the user device to access the first service device when the user device is out of the service area.
