Abstract: A solution for dynamic packet filtering includes, at a network device, if an n-tuple of a packet matches an n-tuple filter, applying an action of the filter to the packet. If the packet has not been discarded as a result of the filter application, and if the packet is identified, by using payload portion, as a network application associated with a filter policy, an n-tuple filter is generated based on the packet. If the application ID of the packet is not associated with a filter policy, the packet is forwarded to the network application.

Abstract: A solution for rapid evaluation of numerically large complex rules governing network and application transactions includes, at a network device, receiving network transaction record comprising a plurality of elements that characterize a network transaction, creating a hash of a result of concatenating the plurality of elements, and if the hash is found in a hash table comprising, for each network transaction rule, a hash of the plurality of elements comprising the rule, blocking the network transaction or alerting a network user that a prohibited transaction has occurred.

Abstract: Systems and methods for a wireless VoIP headset. A wireless VoIP headset including a speaker, microphone, controller for processing a digital audio signal to generate IP packets, and an IEEE 802.11 transceiver. The wireless VoIP headset includes a computer readable memory storing instructions that when executed by the controller cause the wireless VoIP headset to perform a method for originating a call. The method includes receiving a spoken name or number from a user at the microphone, interpreting the spoken name or number using embedded or server based voice recognition, comparing the spoken name or number to a directory stored in the computer readable memory, and generating a call origination request message. The directory may also be stored on an adjunct computing device.

Abstract: A chip component assembly is provided that includes a plurality of chip components each having respective first and second terminal elements, the first terminal elements being joined to corresponding solder pads on a printed circuit board, the solder pads being in communication with electronic circuitry of the printed circuit board, and the second terminal elements being joined together by an array ground plane of a grounding device. The grounding device additionally includes a ground path structure which physically and electrically connects the array ground plane, and thus the chip components, to a ground pad located on the printed circuit board so as to provide a ground path from the chip components. Preferably, the array ground plane additionally includes a plurality of resilient contact elements which provide for substantial and continuous contact between the array ground plane and an ancillary ground plane, such as the top cover of a PC card.

Abstract: An electrical jack system is operable with an electrical plug, such as an RJ-type plug. In one embodiment, the electrical plug is at least partially translucent. The jack system includes a housing bounding a socket. The socket is configured to receive the electrical plug. A light source is coupled with the housing so as to selectively illuminate the socket and/or the translucent electrical plug when the translucent electrical plug is received within the socket of the housing. In one embodiment, the light source is a light emitter, such as an LED, mounted on the housing so as to be at least partially exposed to the socket of the housing. In an alternative embodiment, an opening is formed on the housing in communication with the socket. A light emitter is disposed a distance from the opening on the housing. A conduit extends between the light emitter and the opening. The conduit, such as a light pipe, is configured to channel light from the light emitter to the opening on the housing.

Abstract: Methods and apparatus for providing temperature compensation for a communications card, such as a modem or network card, to minimize retrain sequences between the communications card and another communications card during periods of temperature build-up within the communications card are disclosed. It is a feature of the invention to provide this temperature compensation regardless of the speed or temperature of arriving at a steady state temperature and regardless of the make of the communications card, host computer or computing temperature environment under examination. In a preferred embodiment, a keyword between the communications card and a host computer is compared to provide unique heat compensation for these two devices that have generally different, but consistent, heating characteristics.

Abstract: A method and apparatus for improving the signal-to-noise ratio of low-magnitude input signals that coincide with a noise band of channel noise introduced into the transmission of data across a communication channel. A transmitting and receiving modem establish a communication channel for facilitating the exchange of input signals. The receiving modem evaluates the noise spectrum of the communication channel on a dynamic basis at the commencement of the exchange of information. The transmitting modem suspends transmission while the receiving modem evaluates the noise band and magnitude of the noise information. The channel noise band and levels are transmitted from the receiving modem to the transmitting modem to generate pre-compensation modulation points that have an enhanced magnitude outside the channel noise. The enhanced low-magnitude input signal and all other signals are propagated across the communication channel and exposed to the channel noise.
