    • A method and apparatus utilizing automated semantic pattern recognition whereby a user of a manual enters a query regarding information in the text of the manual and the invention displays the locations in which information responsive to the query is located. The present invention includes a computer that stores a data structure representing the natural language text of a manual, the structure being a tree structure having nodes, wherein each node represents information from associated locations of the text. The nodes at higher levels of the tree represent general categories of information. Nodes at succeedingly lower levels of the tree represent succeedingly more specific categorical subsets of the general categories of information represented at the higher levels by ancestors of the lower level nodes. The query is formatted into a query data structure that is similar in format to the node structure representing the text. The query data structure is compared to each node in the tree. If the degree of similarity between the query and the node exceeds a predetermined threshold value after taking into account the degree of similarity between the ancestors of the node and the query, then the locations associated with the node are displayed on a video monitor as locations containing information responsive to the query.
    • 一种使用自动语义模式识别的方法和装置,其中手册的用户输入关于手册的文本中的信息的查询,并且本发明显示响应于该查询的信息所在的位置。 本发明包括存储表示手册的自然语言文本的数据结构的计算机,该结构是具有节点的树结构,其中每个节点表示来自文本的关联位置的信息。 树的较高级别的节点表示信息的一般类别。 在树的后续较低级别的节点代表由较低级节点的祖先在较高级别表示的一般信息类别的更具体的分类子集。 该查询格式化为与表示文本的节点结构格式相似的查询数据结构。 将查询数据结构与树中的每个节点进行比较。 如果在考虑到节点的祖先与查询之间的相似度之后,查询和节点之间的相似度超过预定阈值,则与节点相关联的位置被显示在视频监视器上,作为包含 响应查询的信息。

    • A keyboard switch includes a plurality of spaced piezoelectric transducers secured to a common strike plate which is selectively impacted to actuate all of the transducers in response to switch actuation. The switch includes a snap action spring member carrying an impact member which impacts the strike plate as the spring member snaps to its actuated state when the switch is depressed . The spring member causes the impact member to maintain a compressive force against the strike plate, maintaining the transducers actuated while the key remains depressed and for a short interval after the key is released. An array of such switches on a keyboard is disposed over a plurality of parallel data lines which electrically contact one or more transducers at each switch in accordance with a switch indentification code. The parallel binary number appearing on the lines is received by processing circuitry which identifies each depressed key by its code. By maintaining compressive forces on the transducers, the system facilitates character processing and generation of certain specialized character functions.
    • 键盘开关包括固定到公共撞击板的多个间隔开的压电换能器,其被选择性地撞击以响应于开关致动来致动所有换能器。 该开关包括一个卡扣动作弹簧构件,该弹簧构件承受冲击构件,当冲击开关被按压时,该冲击构件随着弹簧构件卡入其致动状态而撞击冲击板。 弹簧构件使冲击构件保持抵抗撞击板的压缩力,当钥匙保持按压时,保持换能器的作用并且在钥匙被释放之后的短时间间隔内。 键盘上的这种开关的阵列设置在多​​个并行数据线上,该数据线根据开关识别码在每个开关处电接触一个或多个换能器。 出现在行上的并行二进制数由通过其代码识别每个按下的键的处理电路接收。 通过保持换能器上的压缩力,系统便于字符处理和产生某些专门的字符功能。
