The present invention provides a digital (computational) branch calibrator which uses a feedback signal sensed from an RF transmit signal path following the combining stage of LINC circuitry of a transmitter to compensate for gain and phase imbalances occurring between branch fragment signals leading to the combiner. The calibrator feeds a quiet (zero) base band signal through the transmit path during the calibration sequence (i.e. a period when data is not transmitted) and adjusts the phase and gain of the phasor fragment signals input thereto by driving the sensed output power to zero. The calibration is performed by alternating phase and gain adjustments with predetermined (programmable) and multiple update parameters stages (speeds). A baseband modulation is preferably used to distinguish false leakage (e.g. due to local oscillator, LO, feed through and DC offset in the base band Tx) from imbalance leakage.

A method and apparatus for providing 2-way interactive short message system menus to a mobile device using text-based short messaging rather than WAP techniques. This provides the ability to provide WAP like services at a fraction of the cost of CSD. Mobile Originated Interactive Menus are implemented as a feature of a Short Message Service Center (SMSC). Each option guides either to the next menu level, or to a final action to be executed according to the path followed by the subscriber. Importantly, the mobile originated interactive menus use SMS communications instead of circuit switched data (CSD) (e.g., instead of WAP communications), thus leaving traffic channels available for voice calls. Interactive SMS menus allow service providers to offer their subscribers personalized messaging menus with multiple options for quick and easy access to Web-based content. Users may define the content and frequency they want, whether it is a scheduled delivery or on-demand. The interactive SMS menu options offer customers a simple-to-use technique and apparatus for checking, e.g., stock quotes, local weather, and / or other Web-based news and information when they want it. The interactive nature of the service allows the wireless network to poll the user for their next response, with multiple menued options offered, making it highly intuitive. Replacement of messages in TDMA and GSM mobile devices allow for heavy usage without filling up the user's phone buffer, i.e., prior messages may be overwritten, to assure that only the latest information is all that is being displayed and read. The flexibility of Interactive SMS Menus can allow service providers to define their own base offering of menus, depending upon their targeted customer segments.

A dual ball ramp actuator having a control ring acting with a pressure plates to supply an axial clutch clamping force to a differential clutch assembly where the ball ramp paths follow overlapping eccentric grooves that can be actuated in both the forward and reverse directions. The dual ramp feature doubles the effectiveness and sensitivity when compared to a single ramp system. The overlapping eccentric ball ramps increase (effectively double) the angular travel distance while reducing the ramp angle (in half). The forward and reverse feature provides clutch actuation in both the forward and reverse directions. The dual ramp, 3-piece sandwich construction permits the central control ring to roll up on two sets of balls on each side. This structure doubles the axial travel available to compress a disc pack and lock up the differential with the same ball ramp angle when compared to a single ramp system involving only two ramp plates.

A technique manages paths taken by probe packets sent from a source to a target of a computer network. The novel path management technique enables each probe packet i) to be transferred onto a path of the computer network via a specific exit at the source, ii) to be returned to the source, and iii) to follow a path that closely matches the path followed by user data through the network. Specifically, one or more alternate routing tables are used by the source to select specific exits for the probe packets. Additionally, the source address of the probe packet is configured as a public address (i.e., reachable and used by actual user data traffic) to ensure that the packet is returned to the originating source and follows a path through the computer network that closely matches the path followed by user data traffic.

A method ensures that multicast packets follow the same loop-free path followed by unicast packets in a packet communication network. The communication network includes at least one first area interconnected through at least one area border node (“ABN”) to a second area. Each ABN has a first level port connected to each first area and a second level port connected to the second area. Each multicast packet forwarded includes a header having a root-id identifying a root of a multicast tree. A data packet is received at an ABN. Responsive to receiving a multicast packet at a second level port of an area border node, the root-id of the multicast packet is examined and if the multicast packet is to be forwarded over at least one of the first level ports, a different root-id is substituted into the packet before the packet is forwarded over the first level port.

A method and apparatus are disclosed for monitoring and signaling a path restoration using pre-computed restoration paths following a detected fault on a primary service path in a communications network. A fault occurring inside the restorable portion of a network in heterogeneous or multiple network environments can be distinguished from faults occurring outside the restorable network in accordance with the ANSI Tandem Connection Maintenance standard, T1.105.05-1994. Path restoration is activated only when a fault causing path failure occurs inside the restorable portion of the network. Each conforming node in the restorable portion of the network has the necessary monitoring, signaling and cross-connect functionality and databases to participate actively in real time restoration. Additional non-conforming network elements can be positioned between the restoration nodes without preventing path restoration. With the signaling architecture of the present invention, when an end-node detects a path failure caused by an in-network fault, it formulates a signaling message for restoring the failed path. The restoration signaling message is thereafter relayed from one node to another in the overhead or payload of signaling paths that occupy the same bandwidth that is subsequently used by the restoration path. Once a signaling message is transmitted to an adjacent node in the overhead or payload of a particular signaling path, the node that transmitted the message makes a cross-connect that replaces the signaling path with a segment of the restoration path whose set-up was requested in the transmitted signaling message.

A wafer track and lithography cluster tool for performing a series of processes with a scheduler which synchronizes all events in a substrate processing system. Events in the cluster tool are scheduled to occur at regular, periodic intervals, thereby improving throughput and quality. The scheduler also eliminates conflicts for transportation resources between modules in the cluster tool. Wafers are loaded into the cluster tool at a regular interval, referred to as a sending period. All events in the system are synchronized with the sending period, and all event timings are normalized in terms of the sending period. The conflicts are resolved by selectively adding delays in modules which can tolerate them without degrading throughput or performance in the system; modules that cannot tolerate delays are exempted. The periodicity of the scheduled cluster tool enables the identification of wafers in the cluster tool. The identification of the order in which a wafer was loaded also identifies a module path followed by the wafer.
