摘要:
A controllable equalizer is arranged to be automatically and selectively disabled and is configured to operate in a frequency modulated (FM) radio receiver. The controllable equalizer includes an equalizer (115) that is configured to perform an equalization algorithm, e.g., CMA, that relies on a predetermined distribution for a received signal, where the received signal is available from the FM radio receiver and a spurious signal detector (123) that is configured to determine whether a spurious signal is present in the received signal and to disable the equalizer when the spurious signal is present. A method (300) of automatically and selectively disabling an equalizer operating in a frequency modulated (FM) radio receiver includes performing an equalization algorithm (307) on an FM received signal, the equalization algorithm relying on a predetermined distribution of the FM received signal, determining whether a spurious signal is present (309) in the FM received signal; and disabling the equalizer (317) when the spurious signal is present in the FM received signal.

Described is a technology in which sequential data, such as application program command sequences, are processed into patterns, such as for use in analyzing program usage. In one aspect, sequential data may be first transformed via state machines that remove repeated data, group similar data into sub-sequences, and/or remove noisy data. The transformed data is then segmented into units. A pattern extraction mechanism extracts patterns from the units into a pattern set, by calculating a stability score (e.g., a mutual information score) between succeeding units, selecting the pair of units having the most stability (e.g., the highest score), and adding corresponding information for that pair into the pattern set. Pattern extraction is iteratively repeated until a stopping criterion is met, e.g., the pattern set reaches a defined size, or when the stability score is smaller than a pre-set threshold.

IMS gateway systems and methods are disclosed for providing budget control in an IMS network. IMS networks allow for media changes (e.g., audio to audio/video) during an IMS session. An IMS gateway system described herein receives a session control message (e.g., SIP INVITE message) responsive to the media change during the session. The IMS gateway system identifies media information for the new media in the session control message. The IMS gateway system generates a corresponding charging request message, and includes media information for the new media in the charging request message. The IMS gateway system then transmits the charging request message to an online charging system (OCS) to provide for charging of the session based on the new media for the session.

One embodiment of a quantum well structure comprises an active region including active layers that comprise quantum wells and barrier layers wherein some or all of the active layers are p type doped. P type doping some or all of the active layers improves the quantum efficiency of III-V compound semiconductor light emitting diodes by locating the position of the P-N junction in the active region of the device thereby enabling the dominant radiative recombination to occur within the active region. In one embodiment, the quantum well structure is fabricated in a cluster tool having a hydride vapor phase epitaxial (HVPE) deposition chamber with a eutectic source alloy. In one embodiment, the indium gallium nitride (InGaN) layer and the magnesium doped gallium nitride (Mg—GaN) or magnesium doped aluminum gallium nitride (Mg—AlGaN) layer are grown in separate chambers by a cluster tool to avoid indium and magnesium cross contamination. Doping of group III-nitrides by hydride vapor phase epitaxy using group III-metal eutectics is also described. In one embodiment, a source is provided for HVPE deposition of a p-type or an n-type group III-nitride epitaxial film, the source including a liquid phase mechanical (eutectic) mixture with a group III species. In one embodiment, a method is provided for performing HVPE deposition of a p-type or an n-type group III-nitride epitaxial film, the method including using a liquid phase mechanical (eutectic) mixture with a group III species.

One embodiment of fabricating a p-down light emitting diode (LED) structure comprises depositing a high crystal quality p type contact layer, depositing an active region on top of the p type contact layer, and depositing an n type contact layer on top of the active region using a hydride vapor phase epitaxy (HVPE) process. The high crystal quality p type contact layer is deposited at high temperature to ensure the high crystal quality of the p type film. The n type contact layer is formed on top of the active region in a HVPE chamber at a low temperature to prevent thermal damage to the quantum wells in the active region below the n type contact layer. The processing chamber used to form the p type contact layer is a separate processing chamber than the processing chamber used to form the n type contact layer.

摘要:
Described is a technology in which a finite state machine-based method segments original sequential data into high level units. Segments with similar sub-sequences are treated as the same unit. In general, the finite state machine indentifies sub-sequences in the sequential data that have similar tree-like microstructures. One described finite state machine operates by entering a path state when an input is a path command corresponding to a non-leaf node; the state machine remains in the path state until another command comprises an action command corresponding to a leaf node, whereby it outputs an action unit, or until the other command comprises a path command that is not the parent or the sibling of a next command, whereby a browsing unit is output. Also described is aggregating sub-sequences of a same unit to produce an access structure corresponding to the unit.

Systems and methods are disclosed that determine whether incoming calls are in a home local calling area (LCA) in a wireless network. One embodiment comprises an LCA determination system that includes a processing system and a mapping data structure. The mapping data structure includes a plurality of entries that map a switch/cell identifier (e.g., an MSC/cellsiteID) to a set of LCA identifiers. For a call in a wireless network, the processing system receives a switch/cell identifier, masks the sector identifier from the switch/cell identifier, and searches the mapping data structure based on the masked switch/cell identifier to identify an associated set of LCA identifiers. The processing system then compares the set of LCA identifiers to a subscriber profile to determine if an LCA identifier matches. If there is a match, then the processing system determines that the call is in a home LCA.

A noise blanker for use in a radio receiver includes an audio blanker (115) configured to mitigate impulse noise associated with a signal received by the radio receiver and a blanker controller (117) configured to selectively enable the audio blanker and further comprising at least a first blanker enabler and a second blanker enabler. The noise blanker controlled and corresponding method (500) can include a first noise detector, e.g., MPX noise detector (213), configured to provide a first signal when impulse noise is detected in a demodulated signal and a second noise detector, e.g., log RSSI noise detector (211), configured to provide a second signal when impulse noise is detected in a modulated signal, and a logic function (217) coupled to the first and second signals and configured to provide an enable signal to the noise blanker when the first signal or the second signal is provided. Note that in addition to or in lieu of either of the noise detectors, a switching enabler (215), responsive, e.g., to diversity switching controller (125) or other indications of a state change, can provide a signal to the logic function and thus enable the audio blanker.
