    • The invention provides an apparatus for interacting with a computer system comprising a processor coupled to a display. The apparatus comprises a body configured to be moveable by a user. The body has a position sensor therein for producing a main position signal. A plurality of probe members are connected to the body. A plurality of transducers are coupled to the probe members for producing probe motion signals representative of positions of the probe members. A plurality of actuators are coupled to the probe members to selectively apply force to the probe members. A control system is coupled to the position sensor, the transducers and the actuators for receiving the main position signal and the probe position signals and interacting with the processor in order to produce control signals for controlling each of the probe members.
    • 本发明提供了一种用于与包括耦合到显示器的处理器的计算机系统交互的装置。 该装置包括被配置为可由用户移动的主体。 主体具有位置传感器,用于产生主位置信号。 多个探针构件连接到主体。 多个换能器耦合到探针构件,用于产生代表探针构件的位置的探针运动信号。 多个致动器联接到探针构件以选择性地向探针构件施加力。 控制系统耦合到位置传感器,换能器和致动器,用于接收主位置信号和探头位置信号并与处理器相互作用,以产生用于控制每个探针构件的控制信号。

    • The subject matter described herein relates to managing data with flexible schema. A method, computer storage medium, and system are provided for managing data with flexible schema. The method comprises providing a logical view for logical tables of a database; and managing mappings between the logical tables and a physical table according to predefined mapping constraints, each of the logical table mapped as a part of the physical table. The mapping constraints at least specify that (i) a logical column in the logical tables is mapped to at least one physical column in the physical table, and (ii) distinct logical columns in one of the logical tables are mapped to distinct physical columns in the physical table. As a result, schema evolution may be done with minimized data migration.
    • 本文所述的主题涉及使用灵活的模式来管理数据。 提供了一种方法,计算机存储介质和系统,用于以灵活的模式管理数据。 该方法包括提供数据库的逻辑表的逻辑视图; 并根据预定义的映射约束管理逻辑表和物理表之间的映射,每个逻辑表映射为物理表的一部分。 映射约束至少指定(i)逻辑表中的逻辑列被映射到物理表中的至少一个物理列,并且(ii)其中一个逻辑表中的不同逻辑列映射到不同的物理列 物理表。 因此,可以通过最小化数据迁移来完成模式演进。
