摘要:
A method for realizing network access authentication, wherein a network access authentication device pre-storing a system integrity value of a device waiting to access and a correspondence between each device waiting to access and its system integrity value. When the device waiting to access needs to access the network, it acquires its current system integrity value, and sends the current system integrity value to the network access authentication device; the network access authentication device judges whether the received current system integrity value of the device waiting to access and its stored integrity value of the device waiting to access are identical or not, and in a case where the received current system integrity value of the device waiting to access and its stored integrity value of the device waiting to access are identical, it determines that the network access is authenticated. As such, the network access device could determine the real status of the device waiting to access, and ensure the device accessing to the network is really secure, thereby ensuring the security of the network.

A method of communicating for a communication apparatus, which includes: a terminal apparatus transmitting the information frames to a central office apparatus; the central office apparatus receiving the information frames and obtaining the terminal apparatus information from the information frames; the central office apparatus processing the information frames transmitted from the terminal apparatus, using the terminal apparatus information obtained from the information frames; whereby communication between the central office apparatus and the terminals of different vendors is implemented.
摘要:
Scan modules are provided. A scan module includes a carrier, a first lens fixed to the carrier, a second lens movably connected to the carrier, and an optical sensor fixed to the carrier. The first lens detects light from a scan area through the first lens to the optical sensor along an optical path when the second lens is in a first position and out of the optical path. The second lens intervenes and alters the optical path when in a second position.

This invention provides a method for upgrading the network rate of a Passive Optical Network (PON), which mainly includes: upgrading the optical fiber line rate of the central office device, and adapting, by the network terminal device, the working rate of the upstream/downstream line automatically to the optical fiber line rate of the central office device according to a downstream data flow transmitted from the central office device. Using the method of this invention, the network rate of the PON can be upgraded without replacing the network terminal and without a manual intervention.

A screened subnet for interconnecting an intranet to the Internet includes first and second subnets. A first firewall provides a first level of protection to a portion of the first subnet and to the second subnet while a second firewall provides a second level of protection to the second subnet. A secured utility VLAN provides utility services for the portion of the first subnet and/or the second subnet. The secured utility VLAN is coupled to the screened subnet such that it enjoys an additional level of protection relative to the subnets and/or the portion thereof which it serves. In various embodiments thereof, the screened subnet is configured to include a single, shared, secured utility VLAN for servicing both the portion of the first subnet and the second subnet, or a pair of discrete secured utility VLANs for respectively servicing the portion of the first subnet and the second subnet.
摘要:
A switching regulation system and control scheme efficiently enables driving multiple loads from a common energy storage element, such as an inductor. The control scheme operates to store energy in the energy storage element over a first portion of a cycle, such as by ramping up current through an inductor, according to energy requirements of the multiple loads. After storing the energy in the storage element during the first portion of the cycle, the stored energy is delivered consecutively to each of the multiple loads over a subsequent portion of the cycle.

The present invention provides improved line and load regulation of a switching-mode power converter (300) without requiring additional capacitors (255), either internally or externally, to stabilize the control loop. The present invention can provide this by integrating a digital compensator (375) with the pulse-width modulator (“PWM”) of the switching-mode power converter. Such a compensator (375) can include comparators (310 and 330), digital circuits (340), and resistors (215, 220, 320, and 325).
摘要:
The present invention is a new solution of line and relay in an analog subscriber board, which has a less number of relays and can decrease the cost and save the space while realizing the basic functions in a voice network. The technical solution of the invention provides each subscriber with two relays to connect the subscriber line interface circuit, the subscriber line, the ring bus and the test bus, realizing the basic functions relevant to the talking, such as talking, ringing, etc. In order to add the auxiliary functions such as the testing function and the monitoring function, the subscriber lines are grouped, and at least one relay is supplemented in a subscriber group, the subscriber group relays together with above two subscriber relays will be used to connect the subscriber line interface circuit, the subscriber line, the ring bus and the test bus to perform the basic functions relevant to talking and the auxiliary functions such as testing, monitoring, etc.
