    摘要： Embodiments of the subject invention can utilize a single coil structure for dual-mode operation. In a specific embodiment, a single coil structure can be used as a volume coil in the transmitting phase and as a phase array in the receiving phase. In an embodiment, a transmit coil array in accordance with the subject invention can be utilized for one or more of the following: 1) parallel RF excitation on an MRI scanner equipped with a multiple-channel transmitter; 2) serial RF excitation with the use of a switch system with a single channel transmitter; and 3) generation of a homogeneous B1 field for regular MRI with the use of a power splitter on a standard scanner. In a specific embodiment, the use of a concentric double loop coil with different tunings of inner and outer loops can be implemented. In an embodiment, the coil elements can be decoupled using the CRC mode of a concentric double loop coil. In an embodiment, a surface coil transmit array can provide better compatibility with a receive array. In a specific embodiment, an over-coupled technique can be used to improve the phase control of the transmitting pulse.

    摘要翻译： 本发明的实施例可以利用单线圈结构进行双模操作。 在具体实施例中，单个线圈结构可以用作发射相位中的体积线圈，并且在接收阶段中用作相位阵列。 在一个实施例中，根据本发明的发射线圈阵列可用于以下一个或多个：1）配备有多通道发射器的MRI扫描器上的并行RF激励; 2）使用具有单通道发射器的开关系统进行串行RF激励; 以及3）在标准扫描仪上使用功率分配器产生用于常规MRI的均匀B 1'场。 在具体实施例中，可以实现具有内圈和外圈的不同调谐的同心双环线圈的使用。 在一个实施例中，线圈元件可以使用同心双环线圈的CRC模式去耦合。 在一个实施例中，表面线圈发射阵列可以提供与接收阵列更好的兼容性。 在具体实施例中，可以使用过耦合技术来改善发射脉冲的相位控制。

    摘要： A rail-mounted hanging file arrangement includes a generally horizontally elongated rail which is supported in upwardly spaced relationship from the worksurface so as to extend generally along but above the rear edge thereof. The rail defines therein a longitudinally elongated slot which opens forwardly of the rail, and a file hanging frame is releasably attached to the rail at substantially any position therealong so that the frame is carried entirely by the rail and projects rearwardly a small distance therefrom to permit conventional hanging type files to be stored just rearwardly of the rail adjacent the rear edge of the worksurface. The file hanging frame includes a pair of generally parallel side legs which are spaced so as to permit a plurality of hanging files to be suspended therebetween, and the hang tabs provided on opposite ends of the files can engage the side legs. These side legs of the file hanging frame at their front ends fixedly join to front legs which project downwardly and also slope inwardly in converging relationship with one another. The front legs at the lower ends thereof respectively join to securing legs of short extent which are insertable into the slot of the support rail to fixedly but releasably secure the frame to this support rail.

    摘要： A shallow tray of the type for use on a worksurface or other support top having a construction which enables several such trays to be disposed vertically one above the other and at least partially nested one within another, either when the trays are empty or contain only a small number of documents therein to permit compact storage on a worksurface top while utilizing minimal space. The tray construction in addition allows the trays to be vertically cross-stacked one on top of another to provide for desired vertical separation and hence at least limited visibility and access to the individual trays in the stack, while at the same time providing significant storage capability and document separation while minimizing the amount of space utilized on the worksurface top.

The attachment apparatus generally has a base, a motor and one or more brackets, with the motor positioned in front of the base and the one or more brackets positioned behind the base. A plurality of holes in the one or more brackets having parallel center axes in an attachment plane may be used in coupling the attachment to the excavator. The base of the attachment may have a major plane that is approximately parallel to the attachment plane, and the axis of rotation of the motor may be approximately perpendicular to the major plane of the base. A push plate apparatus is provided for possible use with the main attachment for pushing pipes, etc., into a hole. Furthermore, methods of making and using the present attachment and/or push plate are further provided.

    摘要： The subject invention pertains to a technique and device that can isolate and separate resultant electromagnetic fields of volume coils at high frequency. In an embodiment, an RF shield can be used to isolate and separate resultant electromagnetic fields. In an embodiment, the shield can have a cylindrical shape that can form a partially closed volume in which an object to be imaged, or sample, can be inserted. In an embodiment, the RF shield can be part of a RF coil. In a specific embodiment, some parts of a volume coil can be inside a shield, and the other parts of a volume coil can be outside the shield. The shielding of some of the parts of a volume coil can create conductor patterns corresponding to the specific parts inside the shield and the specific parts outside the shield. In an embodiment, two or more conductor patterns can be placed in proximity to the same shield and either be driven independently, driven together, or act as receiving elements, combined or uncombined. This embodiment is advantageous because the combination of conductor patterns can be optimized by the flexibility of separating the fields of end-rings from the fields of leg currents.

    摘要： A storage bin for storage and containment of cabling associated with work-related items such as computers, telephones and the like. The storage bin is mountable generally along a terminal edge of a furniture component such as a worksurface, so that cabling can be routed from atop the worksurface downwardly into a hollow interior of the bin. The storage bin additionally includes pairs of overlapping side walls at each end of the bin which are movable relative to one another to enable opening and closing of the bin when mounted on the worksurface.
