    摘要： One embodiment of the present invention provides a process for producing a low-visibility retroreflective visual tag, which can be used to identify and/or determine the position of an object. This process involves placing an infra-red-blocking material over a retroreflective substrate to form the low-visibility retroreflective visual tag. This infra-red-blocking material is placed so as to form a pattern, which becomes visible to an infrared sensor when the low-visibility retroreflective visual tag is illuminated by an infra-red light source.

    摘要： A system and method for guiding robotic actions based on external factor tracking and analysis is presented. External factors affecting a defined physical space are tracked through a stationary environmental sensor. The external factors are analyzed to determine one or more of activity levels and usage patterns occurring within the defined physical space. At least one of movements and actions to be performed by a mobile effector that operates untethered from the stationary environmental sensor within the defined physical space are determined. The movements and actions are autonomously executed in the defined physical space through the mobile effector.

    摘要： One embodiment of the present invention provides a system for navigating through information associated with physical objects or locations. During operation, the system detects a multi-resolution visual code placed on or in the vicinity of a physical object or location. The system then determines a level of resolution for the detected code, and decodes the code at the determined level of resolution to obtain the information. Subsequently, the system presents the information to a user, thereby allowing the user to navigate through information associated with the physical object or location.

    摘要： A system and method for performing distributed sequential node localization in active sensor deployment is presented. An equilateral orthogonal reference frame is defined. The reference frame includes s+1 anchor nodes that is placed in s-dimensional physical space. New nodes are sequentially placed in a natural sequential ordering within the s-dimensional physical space to form a sequentially well-connected network. For each of the new nodes, location estimates are obtained for the new node from at least s+1 of the anchor nodes previously placed in the s-dimensional physical space. A location is determined for the new node based on the location estimates. The new node are placed in the s-dimensional physical space as a new anchor node proximate to at least one of the s+1 previously-placed anchor nodes upon satisfactory location determination.

    摘要： A system that optimizes packet transmissions during a convergecast operation in a convergecast network. During operation, the system receives a request to perform the convergecast operation in the convergecast network. In response to the request, the system constructs a convergecast-tree, which includes the base-station and the plurality of nodes, based on hop counts from the plurality of nodes to the base-station. Next, the system linearizes the convergecast-tree so that the convergecast-tree contains a plurality of linear branches. The system then schedules packet transmission for each of the linear branches and each node in each branch based on a set of predetermined criteria to obtain a scheduled order. Finally, the system performs packet transmissions in the convergecast-tree using the scheduled order. Note that performing the convergecast operation in this way substantially optimizes the convergecast operation by reducing a total number of timeslots required to complete the convergecast operation.

    摘要翻译： 一种在融合网络中的Convergecast操作期间优化数据包传输的系统。 在运行期间，系统接收到在Convergecast网络中执行Convergecast操作的请求。 响应于该请求，系统基于从多个节点到基站的跳数来构建包括基站和多个节点的Convergecast-tree。 接下来，系统使收敛树线性化，使得收敛树包含多个线性分支。 然后，系统基于一组预定标准来调度每个分支中的每个线性分支和每个节点的分组传输以获得调度顺序。 最后，系统使用调度顺序在convergecast-tree中执行分组传输。 注意，以这种方式执行Convergecast操作通过减少完成Convergecast操作所需的时隙的总数大大优化了Convergecast操作。
