    摘要: Sectorisation has been used in cellular communications networks in order to increase capacity without the need for obtaining new cell sites. However, previously, the increase in the number of main antenna beams provided by a base station transceiver has not produced a commensurate increase in capacity. For example, a hex sectored tricellular network is found to provide an increase in capacity by a factor of only 1.6 over a tri sectored tricellular network despite the fact that twice as many antenna beams are provided. A multiple beam antenna arrangement is described where the increase in capacity is commensurate with the increase in the number of antenna beams provided. In one example, a nine sectored tricellular CMDA network is described which comprises a multiple beam antenna arrangement with six antenna elements each provided as columns. The antenna beams may be orthogonal and a 6×6 Butler matrix beamformer is used which is advantageously loss less. The beamformers may be arranged back to back to allow sharing of power amplifiers to reduce costs and complexity and the number of cables required is reduced by the particular arrangement of beamformer used.

    摘要: Sensor device for ion channel recordings; liquid-liquid measurements and resistive pulse particle counting comprising; at least one sensor element; the element comprising a diamond thin film substrate and a pore which is a nanopore or a micropore included in the substrate. This device may be used in analysis, for instance the device may be used for single molecule detection of an apialyte (e.g. DNA), for the analysis of interactions between a sensor element and an analyte, for the detection of pore forming entities, or for the determination of ion transfer.

    摘要: An axial retention system for restraining axial movement of a first machine component having a dovetail within a complimentary-shaped dovetail slot in a second machine component that includes a first curved groove formed in a bottom surface of the dovetail slot and a second curved groove formed in a bottom surface of the dovetail. The first and second grooves are in alignment when the dovetail is located within the dovetail slot to thereby form a closed periphery aperture. A curved locking clip is received within the closed periphery aperture. An optional cover plate may be placed over the ends of the locking clip, with ends of the locking clip deformed by, for example, swaging.

    摘要: Rearview assemblies for a vehicle are provided. The rearview assembly includes a housing coupled to a mounting structure that is configured to be mounted in a vehicle. The housing includes a rearward viewing means, and also includes a lamp subassembly. The lamp subassembly includes a single white LED device mounted to a substrate, and also includes an optical assembly with secondary optics for reflecting and refracting light emitted from the LED such that the emitted light forms two separate pools of light external to the rearview assembly. In an alternate embodiment, the lamp subassembly is included in a mounting structure for a vehicle rearview assembly. In still another embodiment, a vehicle optical accessory is provided, in which the vehicle optical accessory has one LED that provides two separate pools of light external to the vehicle optical accessory.
