    • New methods and configurations are provided that allow for a large memory capacity, as well as minimized interconnect distances between the memory chips and one or more processors, and the HUB chip-set. The apparatus, configurations and methods include providing a printed circuit board having one or more processor conductive portions and one or more z-axis connector conductive portions in close proximity with each other, and connecting the one or more processors on one side of a printed circuit board, and connecting the one or more z-axis connectors for the memory daughter cards on the opposite side of the processor board. Standoffs are used to support and secure the horizontally disposed z-axis memory daughter cards and to ensure proper spacing between the z-axis daughter cards and the processor board Standoffs include an alignment pin portion and a spacer portion. The alignment pin portion includes an alignment portion, foot, and urging portion. The spacer portion includes pin coupler, relief portion, and aperture. The standoff is inserted into an aperture of a first printed circuit board and turned 90 degrees to secure the spacer portion and the foot to the first printed circuit board. An aperture in a second printed circuit board is slid over the alignment pin portion, wherein the second printed circuit board rests on the spacer portion. The fastening means is used through an aperture in the second printed circuit board communicating with the spacer portion.
    • 提供了新的方法和配置,其允许大的存储器容量以及存储器芯片与一个或多个处理器之间的最小化互连距离以及HUB芯片组。 该装置,结构和方法包括提供具有一个或多个处理器导电部分和一个或多个彼此紧密接近的z轴连接器导电部分的印刷电路板,以及连接印刷电路一侧上的一个或多个处理器 并将处理器板相对侧的存储器子卡的一个或多个z轴连接器连接起来。 支座用于支撑和固定水平放置的z轴存储器子卡,并确保z轴子卡与处理器板之间的适当间隔。支座包括对准销部分和间隔部分。 对准销部分包括对准部分,脚部和推动部分。 间隔部分包括销联接器,浮雕部分和孔。 将间隔插入第一印刷电路板的孔中并转动90度以将间隔件部分和脚固定到第一印刷电路板。 第二印刷电路板中的孔径在对准销部分上滑动,其中第二印刷电路板搁置在间隔部分上。 紧固装置通过与间隔件部分连通的第二印刷电路板中的孔而使用。

    • A system and process for providing a geometric model database for use in an ubiquitous computing environment. In general, the geometric model database system and process is capable of accepting information about the geometric state of the environment, building a geometric model of this environment, maintaining and storing the geometric model, and handling queries about the environment's geometric state. The task of building a geometric model begins by establishing a set of entities that are of interest in the environment. An entity represents an object which exists in the physical world. In the geometric model database, an entity is represented by a coordinate frame and an extent. Extents refer to the physical size, or some service region such as a field of view, associated with an entity. The location of an entity in the physical world is defined using “measurements”. In general, a measurement is simply a mathematical description of the geometric relationship between two entities. More precisely, a measurement describes the position and orientation of one entity's coordinate frame, expressed in terms of another entity's coordinate frame. Measurements originating at an entity's frame are expressed in terms of that frame. While various mathematical representations of the geometric relationship between entities could be employed, a preferred one characterizes a measurement as the relative position, and the relative orientation or heading, of two entities along with a covariance matrix which describes the uncertainty in these values.
