Abstract: A low-cost security management system for a wireless network utilizes client software having one component that runs on trusted access points and another that runs on wireless client cards on a client PC and/or laptop that enables an administrator to log in and check the status of network security from any client pc. The software monitors the state of the wireless network and reports on unauthorized connections or hacking attack, denial of service attack and potential threats to the security of the network.

Abstract: A network device, such as a router or switch, has a CPU and a memory operable to receive, store and output computer code. The code includes device configuration files, traffic pattern files, and standard-behavior-output template files adapted for detecting network device functional defects and bottlenecks. The device is operable in a testing mode to act as either a Device Testing Doctor (DTD) or a Device Under Test (DUT), in which it loads into or accepts from a related, interconnected and similarly configured and operable network device selected ones of the device configurations, transmits to or receives from the other device selected ones of the input traffic patterns, compares its own output or that of the other device in response to the input traffic pattern with selected ones of the standard-behavior-output templates, and detects a network device defect or bottleneck in itself or in the other device based on the comparison.

Abstract: In accordance with an embodiment of the present invention, a client device includes a biometric unit, a transceiver unit, and a cryptographic engine. The biometric unit generates a first biometric feature at a first time and a second biometric feature at a second time based on sensing a portion of a human body. The transceiver unit sends and receives message data over a network. The cryptographic engine encrypts and decrypts message data, generates client public and private keys associated with a client device identifier, and generates biometric public and private keys associated with the first user biometric feature. The cryptographic engine encrypts a hash of a first message data using the biometric private key when the first and second biometric features match, and appends the encrypted hash forming an authenticated first message data that is encrypted by a server public key and sent over the network.

Abstract: Systems and methods are provided to facilitate the display of status information associated with a network device using a plurality of multi-function status indicators, such as light emitting diodes (LEDs). In one implementation, a network device includes a plurality of user-viewable status indicators adapted to display status information associated with the network device. The network device further includes a processor adapted to detect a plurality of event conditions at the network device. A logic circuit of the network device is adapted to determine first and second sets status information to be displayed by the status indicators. A control circuit of the network device is adapted to provide the status indicators with display states associated with the first and second sets of status information without requiring user interaction with the network device. The event conditions may be multiplexed to identify associations between the event conditions and the display states.

Abstract: A security access method and/or apparatus is disclosed in the present invention. The present invention discloses a security method that verifies both the user's fingerprints and the fingerprint entering sequence to determine whether an access can be authorized. By using both the fingerprints and the entering sequence as the access criteria, a highly secured device can be created using low cost commercial available components.

Abstract: This invention provides a method and apparatus for providing easily adaptable and select transmission and reception rates between a number of clients and a server. With this invention a broadband signal is transmitted/received from the server to the clients, who individually may need to receive/transmit only a small portion of the composite signal. More specifically, this invention uses discrete multiple tone coding to provide the easily adaptable and selected transmission rates to the clients.

Abstract: An efficient light coupling apparatus for interconnecting two optical components. Light radiation from the first optical component, for example an optical light fiber is directed onto the plane surface of the second optical component, for example a passive waveguide. The light is directed onto the second optical component at a convenient angle such that it impinges on the plane surface of the second optical component at an incident angle. An angularly selective coupling means, for example a volume hologram is located between the first and second optical components for coupling a maximum amount of the light at the incident angle.
