摘要： A steering current generator for a phase interpolator has a multiplicity of fine phase adjustment current sources, each of which is switchable to direct its current to one or other of two summing nodes. The current of each of those two summing nodes is supplemented by respective fixed always-on current sources. The steering current generator has four current outputs and a switching matrix is provided to switch the current from the summing nodes to first and second selected ones of those outputs. The switching matrix is also connected to switch bleed currents to the other two of the current outputs.

摘要： Shaped electrodes for micro-electro-mechanical-system (MEMS) devices to improve actuator performance and methods for fabricating the same are disclosed. The shaped electrodes utilize its three-dimensional geometry to shape an electric field for electrostatic actuation for MEMS devices. For example, the height, width, length, sidewall slope, and layout of the shaped electrodes can be used to provide an optimum electric field in moving a MEMS mirror device. The shaped electrodes can provide electrostatic actuation at a low operating voltage and provide an optimum electric field for maximum tilt or angular range of motion for a MEMS mirror device. The shaped electrodes can be fabricated simply by using a pillar wafer and an electrode wafer. The pillar wafer can be used to form pillars as electrodes, or, alternatively, as barriers. A single substrate can also be used to form pillars and electrodes.

摘要： A system and method for speech-responsive voice messaging, in which a Speech-Responsive Voice Messaging System (SRVMS) preferably provides a hierarchically-simple speech user interface (UI) that enables subscribers to use speech to specify commands such as mailboxes, passwords, and digits. The SRVMS generates and evaluates candidate results. The SRVMS invokes a speech UI navigation operation or a voice messaging operation according to the outcome of the evaluation of the candidate results. In the preferred embodiment, the SRVMS determines whether the candidate results are good, questionable, or bad; and whether two or more candidate results are ambiguous due to a likelihood that each such result could be a valid command. If the candidate results are questionable or ambiguous, an ambiguity resolution UI prompts the subscriber to confirm whether the best candidate result is what the subscriber intended. In response to repeated speech recognition failures, the SRVMS transfers the subscriber to a Dual Tone Multi Frequency (DTMF) UI. Transfer to the DTMF UI is also performed in response to detection of predetermined DTMF signals issued by the subscriber while the speech UI is in context. The SRVMS provides a logging unit and a reporting unit which operate in parallel with the speech UI, in a manner that is transparent to subscribers. The logging unit directs the selective logging of subscriber utterances, and the reporting unit selectively generates and maintains system performance statistics on multiple detail levels.

摘要翻译：一种用于语音响应语音消息的系统和方法，其中语音响应语音消息系统（SRVMS）优选地提供分层简单的语音用户界面（UI），其使订户能够使用语音来指定诸如邮箱，密码，和数字。 SRVMS生成并评估候选结果。 SRVMS根据候选结果的评估结果调用语音UI导航操作或语音消息传送操作。在优选实施例中，SRVMS确定候选结果是否良好，有问题或不好; 以及由于每个这样的结果可能是有效的命令的可能性，两个或更多候选结果是否是模糊的。如果候选结果是有问题或不明确的，则歧义解决UI提示用户确认最佳候选结果是用户想要的结果。响应于重复的语音识别故障，SRVMS将用户传送到双音多频（DTMF）UI。响应于在语音UI处于上下文中时由用户发出的预定DTMF信号的检测也执行到DTMF UI的传送。 SRVMS提供了一种记录单元和报告单元，其以与用户透明的方式与语音UI并行操作。记录单元指示用户话语的选择性记录，并且报告单元在多个细节级别上选择性地生成和维护系统性能统计。
