摘要： A method includes receiving one or more learning configurations, each learning configuration related to an acceptable arrangement of items within an environment. The method further includes extracting from the learning configurations representative item information and relationship information, synthesizing a configuration of items for a defined environment based at least in part on the extracted representative item information and relationship information, determining a cost of the synthesized configuration, and, based on the cost of the synthesized configuration, identifying the synthesized configuration as acceptable.

摘要： A link device establishes links automatically to all 10Base-T and 100Base-TX partners regardless of their capability thereby assuring that the link device establishes links with all partners without the need to select a mode of operation manually. The modes of operation provided include 10Base-T half duplex, 100Base-TX half duplex, and 100Base-TX full duplex. The technique includes an algorithm that assures linkability between 10Base-T and 100Base-TX devices that are not 100% compliant with IEEE 802.3u, Clause 28. Using this algorithm, a link device links with 10Base-T and 100Base-TX half duplex legacy partners. Such devices also link with compliant 10Base-T and 100Base-TX auto-negotiating partners at 100Base-TX full duplex, and with non-compliant 10Base-T and 100Base-TX auto-negotiating devices at 100Base-TX half duplex.

摘要： Processes and techniques for imparting three-dimensional visual characteristics to images in a two-dimensional space are described. In one implementation, a graphical image is received in a two-dimensional space (e.g., a user interface on a computing device). A shape palette is presented to a user, the shape palette comprising a visual representation of three-dimensional visual information. Based on user markup of the shape palette, three-dimensional visual information is extracted from the shape palette and correlated with the graphical image. The three-dimensional visual information is processed to render the graphical image with three-dimensional visual characteristics.

摘要： An asynchronous time-hopping multiple access "(ATHMA") protocol and a simplex mode communication system utilizing the same requires no synchronization between transmitting stations, no handshaking between transmitters and receivers and no system manager to coordinate data message transmission. The ATHMA protocol ensures that for an n-channel asynchronous simplex mode communication system, each transmitter repeatedly sends each unique data message n successive times according to its own time-hopping schedule. In the preferred embodiment the time-hopping schedules are coordinated such that at least one duplication of each unique message will not collide with any other messages over a given period. Thus, at most n-1 transmissions out of the total n transmissions of each unique data message will be collided and lost. The ATHMA protocol and communication system of the present invention is ideally suited for applications requiring a low throughput rate and channel capacity. The ATHMA protocol can be applied to various transmissions media such as radio, infrared optics and wired media with little or no modification.

摘要翻译： 异步跳时多址“（ATHMA”）协议和使用该异步跳频多址通信系统的单工模式通信系统不需要发送站之间的同步，发射机和接收机之间没有握手，也没有系统管理员协调数据消息传输。 ATHMA协议确保对于n信道异步单工模式通信系统，每个发射机根据其自身的跳频计划重复地连续发送每个唯一的数据消息。 在优选实施例中，时间跳跃计划被协调，使得每个唯一消息的至少一个重复将不会在给定时间段内与任何其他消息冲突。 因此，在每个唯一数据消息的总共n个传输中，至多n-1个传输将被冲突和丢失。 本发明的ATHMA协议和通信系统理想地适用于需要低吞吐率和信道容量的应用。 ATHMA协议可以应用于各种传输介质，如无线电，红外光学和有线介质，很少或没有修改。

摘要： A process for the preparation of hermetically sealed electronically active microstructures involves the preparation of a plurality of microstructures and associated conductive paths and lead bond areas on a single wafer such that areas surrounding the microstructures are maintained in a planar condition. A second wafer having a plurality of microstructure-receiving cavities is placed atop the first wafer and fusion or anodically bonded. The microstructures are preferably connected to lead bond pads which lie outside the surround, the second wafer also having bond pad accessing through-holes to facilitate bonding electrical leads to the devices after sawing from the wafer. The lead-connected devices may be further encapsulated by injection molding, potting, or other conventional encapsulative packaging techniques.
