Abstract: The present disclosure relates to a composite lithium battery separator and a preparation process therefor. The composite lithium battery separator includes a base film or a ceramic film, and a coating layer covering one side or both sides of the base film or the ceramic film. The coating layer is formed by coating a slurry. The slurry includes 5%-45% by weight of a coating polymer and 55%-95% by weight of an organic solvent, and the coating polymer includes 10-100 parts by weight of a fluorine or acrylic resin polymer, 0.5-10 parts of a polymer adhesive, and 0-90 parts of inorganic nanoparticles.

Abstract: The present disclosure relates to an electronic device and a method executed by the electronic device, and a computer-readable medium. The electronic device includes a memory on which instructions are stored and a processor. The processor is configured to execute the instructions stored on the memory to cause the electronic device to execute the following operations: receiving a Simple Network Management Protocol (SNMP) request from a network management station; in response to the receipt of the SNMP request, starting a timer at the electronic device, a timeout period of the timer being set to a first predetermined time period; and in response to a case where the electronic device has not completed an operation required by the SNMP request when the timer expires, sending a timeout message to the network management station as a response to the SNMP request.

Abstract: The present disclosure is directed to a method, apparatus and computer medium for switching a user terminal, and an access point. The method may be performed by an access point capable of operating in at least a first band and a second band, and comprises the following steps: in response to determining that a user terminal being in the first band of the access point satisfies a condition for inter-band switching, measuring a communication performance of the user terminal in the first band as a first metric; after the user terminal is switched from the first band to the second band of the access point, measuring a communication performance of the user terminal in the second band as a second metric; and causing the user terminal to be in the band associated with a better one of the first metric and the second metric.

Abstract: Embodiments of the systems and methods disclosed herein relate to a modem having a processor including a Unified Extensible Firmware Interface (UEFI) driver. The UEFI driver can be configured to provide a software interface between an operating system for the modem and firmware for the modem. The modem can include a boot diagnostic driver configured to run from the UEFI driver and execute a diagnostic test when the modem is booting up. The boot diagnostic driver can be configured to generate a signal based on a result of the diagnostic test.

Abstract: A network device for use with a network. The network device includes a memory and a processor configured to execute instructions stored on the memory, to cause the network device to: open a port to enable at least one of enabling outbound communication to exit out of the network device and into the network, and enabling inbound communication to enter into the network device from the network; start a port timer based on the opening of the port; reset the port timer based on at least one of the outbound communication exiting into the network and the inbound communication entering from the network; and perform a port auditing action based on the port timer reaching a threshold.

Abstract: The disclosure relates to methods, routers, media and apparatus for implementing enhanced UPnP subscriptions. According to an embodiment of the disclosure, there is provided a method for implementing an enhanced UPnP subscription, comprising, by a UPnP-enabled router: receiving a subscription message for a subscription, wherein the subscription message specifies a delivery uniform resource locator (URL), the delivery URL is a location where an event message targeted by the subscription is to be sent; checking, based on a whitelist, whether an IP address or a domain name in the delivery URL is contained in the whitelist; and determining whether to reject the subscription message based on the checking result. Through embodiments of the disclosure, both flexible subscription and high security can be achieved.

Abstract: An electronic device features enhanced detection of potential bricking. A processor of the electronic device is configured to, after initiation of a download: (i) check data components defining download parameters of the electronic device; (ii) start a buffer and receive each of the data components; (iii) write each of the data components into flash memory; (iv) read each of the data components from the flash memory and perform a cyclic redundancy check (CRC) of each of the data components; (v) check a signature of each of the data components; (vi) update download settings in the non-volatile random access memory (NVRAM) based on results of (i), (iv) and (v); (vii) check client identifier information of the electronic device; (viii) check access identifier information of the electronic device; and (ix) accept the download if no error is detected and reject the download if any error is detected.
