Abstract:
The problem of tracking rapid changes in the echo signals associated with modems is eliminated by using an echo canceler consisting of cascaded adaptive filters. Each filter in the structure contributes to the modeling of the overall echo path impulse response, with a longer filter providing the ability to model long echo path impulse responses and a shorter filter providing the ability to track changes in the echo path impulse response over time.
Abstract:
Foaming apparatus for foaming a water detergent mixture using compressed air comprises a housing having an elongated main bore extending therethrough. An upstream portion of the main bore is tapered in a generally downstream direction. A jet of water detergent mixture is delivered axially into the tapered portion of the main bore through a first orifice. Four second orifices extending transversely into the tapered portion deliver compressed air for mixing with and foaming the jet of water detergent mixture. Foamed water and detergent mixture is delivered through an outlet at the downstream end of the bore.
Abstract:
A system (2) for facilitating responsible behavior by an entity comprising an identification means (32) for identifying the entity, a facility (4) for verifying the identification means and facilitating pursuit of the behavior, a storage means (18) coupled to be in communication with the facility (4) for storing information related to the pursuit of the behavior by the entity, a modeler module (24) for comparing the information related to the pursuit of the behavior by the entity with a behavior model to determine a category of behavior of the entity and a resolver module (22) for determining one or more actions to be initiated in relation to the entity and their pursuit of the behavior such as initiating a change to one or more operating parameters of the facility (4) in response to the activation of one or more limits, blocks or triggers related to the entity.
Abstract:
A lift and secure latch assembly for a vehicle tailgate includes a pair of cables capable of applying upward force to the tailgate and a tensioning mechanism positioned within the tailgate and connected to the support members to apply tension thereto. One of the cables extends from a first lateral end of the tailgate and the other of the cables extends from a second lateral end of the tailgate. The tensioning mechanism is operable between a first position wherein the cables are retracted with the tailgate closed and a second position wherein the cables are extended with the tailgate open. The tensioning mechanism includes a spring member biasing the tensioning mechanism toward the first position. A latch selectively engages the tensioning mechanism to releasably secure the tensioning mechanism in the first position with the tailgate closed. Preferably, the latch is centrally positioned between lateral ends of the tailgate.

Abstract:
Methods and systems are provided for securely providing and retaining phone numbers. A party name is provided and an associated phone number, which is encrypted employing an encryption algorithm. The party name is added to an electronic phone list, while the associated telephone number is retained in an encrypted state. A user can select the caller name from the electronic phone list for placing a call. The associated phone number is then decrypted, and the call made employing the decrypted phone number. The decrypted version of the phone number can then be removed or erased from memory. Therefore, the decrypted version of the telephone number is not available for viewing by the user or accessible to an undesirable party that may acquire access to the electronic phone list.
Abstract:
A wireless mobile telephone for connecting to multiple networks that includes a cellular module for routing calls through a cellular telephone network, a wireless network module, operably connected to the cellular module, for routing calls on a wireless local area network (WLAN). The mobile telephone provides simultaneous connectivity to a cellular network and a WLAN and automatically detects and configures the mobile telephone to the WLAN when the mobile telephone enters a WLAN broadcast area using pre-programmed operating profiles for each different WLAN.
Abstract:
An optical communications network configured in a shared protect capacity architecture. The network includes a plurality of shared and unshared nodes; a plurality of working lines connecting the plurality of nodes to form a ring that shares two or more nodes with another ring; a shared protect fiber optic line connecting the two shared nodes; and a plurality of protect lines connecting the plurality of unshared nodes which are connected by the plurality of working lines. By optically coupling a first Add-Drop Multiplexer of a first shared node to a first port of an optical cross connect using a first connecting path; optically coupling a second Add-Drop Multiplexer of the first shared node to a second port of the optical cross connect using a second connecting path; and optically coupling a third port of the Optical Cross Connect to a second shared node through a shared protect path, both rings may use the shared protect path to re-route traffic therethrough in the event that one of the rings has a break which severs the working and protect lines which couple two of the nodes thereof. The reduction in the quantity of protect lines, hence the fiber, and the equipment resulting in the associated cost savings are transparent to bit or baud rate, type of optical fiber, and signal format.
