WCDMA transmit architecture
Wideband-Code Division Multiple Access (W-CDMA) transmit architecture. A baseband digital processing module operates cooperatively with an analog signal processing module to effectuate highly adjustable and highly accurate gain adjustment in accordance with transmitter processing within a communication device. The gain adjustment and/or gain control is partitioned between the digital and analog domains by employing two cooperatively operating digital and analog modules, respectively. Gain adjustment in the analog domain is performed in a relatively more coarse fashion that in the digital domain. If desired, gain adjustment in each of the analog and digital domains is performed across a range of discrete steps. The discrete steps in the analog domain are larger than the discrete steps in the digital domain. Also, the discrete steps in the digital domain may be interposed between two successive discrete steps in the analog domain. |

EOS instructions route the call to a POTS number in the originating LATA using an IntraLATA Carrier Identification Code. The POTS number is connected to a private gateway, which utilizes the Dialed Number Identification Service (DNIS) of the POTS number to perform a translation function, which may replace the received DNIS with the DNIS of the originally dialed TF number. The call is routed over the private network using the private network owner's database for routing instructions for the specific TF number. The call is routed through a dedicated connection to a facilities-based carrier or called party or through a switched connection to an egress SSP or local CO. |

A system, method, and apparatus for handling transition errors is presented herein. The transition errors include handling unreported time base discontinuities during trick mode transition, miscalculated time stamps during trick mode transition, erroneous sequence end codes, and unreported broken group of picture transmission.

Miscalculated time stamps are detected by examining the difference in PTS values between temporally adjacent data packets. If the difference is not within a margin of error from predetermined value, the PTS is disabled. Unreported broken groups of pictures are handled by skipping the first two B-frames of the first group of pictures following a trick mode transition. Erroneous sequence end codes are detected by determining whether a packet containing a sequence end code is associated with a time base change. If the packet is not associated with a time base change, the sequence end code is disregarded. |

Mechanism to improve preemption behavior of resource reservations
A technique is provided for one or more network nodes to deterministically select data flows to preempt. In particular, each node employs a set of predefined rules which instructs the node as to which existing data flow should be preempted in order to admit a new high-priority data flow. The rules are precisely defined and are common to all nodes configured in accordance with the present invention. Illustratively, a network node not only selects a data flow to preempt, but additionally may identify other “fate sharing” data flows that may be preempted. As used herein, a group of data flows has a fate-sharing relationship if the application instance(s) containing the data flows functions adequately only when all the fate-shared flows are operational. In a first illustrative embodiment, after a data flow in a fate-sharing group is preempted, network nodes may safely tear down the group's remaining data flows. In a second illustrative embodiment, when a data flow is preempted, all its fate-shared data flows are marked as being “at risk.” Because the at-risk flows are not immediately torn down, it is less likely that resources allocated for the at-risk flows may be freed then subsequently used to establish relatively lower-priority data flows instead of relatively higher-priority data flows. |

The width and location of a hysteresis window of an interferometric modulator may be altered by adjusting various physical characteristics of the interferometric modulator. Thus, depending on the particular application for which the interferometric modulators are manufactured, the width and location of the hysteresis window may be altered. For example, in some applications, reducing the power required to operate an array of interferometric modulators may be an important consideration. In other applications, the speed of the interferometric modulators may be of more importance, where the speed of an interferometric modulator, as used herein, refers to the speed of actuating and relaxing the moveable mirror. In other applications, the cost and ease of manufacturing may be of most importance. Systems and methods are introduced that allow selection of a width and location of a hysteresis window by adjusting various physical characteristics. |

Structure of a key
A keyboard device has a plurality of keys, each key having a support base where one end of each key is supported and is arranged to allow for movement, and a plate that hides the surface of the base. The keys are created with ultrasonic welding once the base and the plate merge. Thus, it is possible to weld while merging the base and the plate together, because the base and the plate are connected by ultrasonic welding. Compared to pasting the two together using traditional adhesives, it is possible to have the base securely bound to the plate. It is then possible to have performers use the device for an extended period of time. The result is the ability to curb the chances of the base and the plate becoming loose. |
