摘要： The present invention is directed to locating and imaging with a swallowable sensor device disposed in a patient. The swallowable sensor device transmits an acoustic signal from inside a patient's body. A plurality of sensing elements receive the acoustic signal. A computation module determines a location of the swallowable sensor device with respect to the plurality of sensing elements based on the acoustic signal received by at least a subset of the plurality of sensing elements. A three-dimensional image of an interior portion of the patient can also be formed based on the received acoustic signal. The three-dimensional image may be formed by stereoscopically displaying two two-dimensional images of the interior portion, wherein the two two-dimensional images correspond to the swallowable sensor device being located at two different locations. Alternatively, the three-dimensional image may be formed by computing three-dimensional pixels of the interior portion.

摘要： The present invention provides methods and apparatuses for demodulation and decoding of backscattered RFID tag signals, represented by their in-phase and quadrature components at the output of the demodulator in the receiver portion of a reader interrogator. Correlation coefficients for the in-phase and quadrature components of the received signal are calculated over a shifted bit interval. Performing a correlation over a shifted bit interval relative to the real bit interval allows the base-band receiver to involve a two-bit interval in making a decision about each transmitted bit. In contrast, in a conventional decoding algorithm, a single bit interval is involved in the decision-making process. Thus, the current method provides a 3 dB energy gain compared to the conventional method. A single zero-mean reference signal is used to compute correlation coefficients, eliminating constant components of the received signal, and simplifying digital implementation of the base-band receiver. A value of the output data is determined based on the combined correlation coefficients.
摘要翻译：本发明提供了用于在读取器询问器的接收机部分中的解调器的输出端由其同相和正交分量表示的背散射RFID标签信号的解调和解码的方法和装置。在移位的位间隔上计算接收信号的同相和正交分量的相关系数。在相对于实际比特间隔的移位比特间隔执行相关性允许基带接收机涉及两比特间隔以作出关于每个发送比特的决定。相比之下，在传统的解码算法中，在决策过程中涉及单个位间隔。因此，与常规方法相比，当前的方法提供了3dB的能量增益。使用单个零均值参考信号来计算相关系数，消除接收信号的常数分量，并简化基带接收机的数字实现。基于组合的相关系数确定输出数据的值。

摘要： Method of integrating Flex and Yacc (or their respective equivalents) into a named entity recognition engine used as a component of a general text processing system is provided. The named entity recognition engine adds results into a central representation or lattice for use by various subsequent applications. The applications can configure which named entity classes or types are recognized via an application program interface. The text processing system configures input and output through the lattice for Flex and Yacc to maintain high performance. Optionally, the text processing system minimizes expensive lexicon look-up by maximizing named entity constituents matched by Flex-generated recognizers.

摘要： Methods of identifying named entities in natural language text using machine or computer compiler tools are provided. A lexical analyzer generator such as Flex or Lex or an equivalent tool can be used to generate a recognizer for named entities, such as digits, date expressions, and email or web addresses. Alternatively, a parser generator, such as Yacc or Bison or an equivalent tool can be used to generate a recognizer for other named entities, such as person and company names. Further, a lexical analyzer generated by Flex, Lex, or its equivalent is used in combination with a parser generated by Yacc, Bison, or its equivalent to identify named entities. Multiple lexical analyzers and/or parsers identify one or more classes of named entities, such as email addresses or person names. In many embodiments, recognized named entities can be used to construct at least one index of web pages or documents including named entities that can be accessed by a natural language processing application.

摘要： A computer-readable medium stores a first lexicon data structure for lexicon words. The first data structure includes a host form variant field containing a host form variant such as a clitic host form variant, a host form field containing the host form of the host form variant (only present if the forms differ) such as a clitic host verbal form, and a verification field indicative of whether the host form variant is a valid word. The first data structure also includes a segment association field containing data or segmentation bits associating the host form variant with certain types of attachment entries in the lexicon, which also contain data or segmentation bits, to define valid combinations between the host form variant and at least one of the attachment entries in the lexicon. A second lexicon data structure for each of the attachment entries in the lexicon is also stored.
