    • A flow assembly for an axial turbomachine is disclosed. The flow assembly comprises: an outer shroud; an inner hub; and, at least one blade mounted to one of the shroud and hub and comprising pressure and suction surfaces. The other one of the shroud and hub comprises a wall and the or each blade extends towards the wall such that a clearance gap is provided therebetween. The flow assembly is configured such that, in use, fluid flows through the flow assembly from an upstream side to a downstream side of the flow assembly. The wall comprises a recirculation channel comprising an outlet and an inlet located between the outlet and the downstream side of the flow assembly. The recirculation channel is configured such that when fluid flows through the flow assembly from the upstream side to the downstream side, fluid flow from the pressure surface side of the at least one blade enters the inlet and flows along the recirculation channel to be expelled from the outlet to impede leakage of fluid flow in the clearance gap from the pressure surface side to the suction surface side of the or one of the blades.

    • An X-Ray analysis device comprising an X-Ray source and an X-ray detector and a method of analysis are disclosed. The X-ray source is arranged to emit a first characteristic X-Ray line and a second characteristic X-Ray line both incident on the sample. The X-Ray detector is adapted to detect X-rays diffracted by the sample. Each of the first and second characteristic X-Ray lines is diffracted at a distinct diffraction angle determined by each of the first and second lattice spacings to produce four diffraction angles, and two of the diffraction angles correspond to one another.

    • The invention provides a two-step approach to providing a BCI system. In a first step the invention provides a low-power implantable platform for amplifying and filtering the extracellular recording, performing analogue to digital conversion (ADC) and detecting action potentials in real-time, which is connected to a remote device capable of performing the processor-intensive tasks of feature extraction and spike classification, thus generating a plurality of predetermined templates for each neuron to be used in a second processing step. In the second step the low-power implantable platform amplifies and filters the extracellular recording, performs ADC and detects action potentials, which can be matched on-chip to the predetermined templates generated by the external receiver in the first step. This two-step approach exploits the advantages of both offline and online processing, providing an effective and safe method for performing multiple recordings of single-neuron activity, for research or monitoring applications or for control of a remote device.
    • 本发明提供了一种提供BCI系统的两步法。 在第一步中,本发明提供了一种用于放大和过滤细胞外记录,执行模数转换(ADC)和实时检测动作电位的低功率可植入平台,其连接到能够执行处理器的远程设备 特征提取和尖峰分类的重点任务,从而为在第二处理步骤中使用的每个神经元生成多个预定模板。 在第二步中,低功率可植入平台对细胞外记录进行放大和滤波,执行ADC并检测动作电位,该动作电位可以在片内匹配到第一步中由外部接收器生成的预定模板。 这种两步法利用了离线和在线处理的优点,为进行单神经元活动的多个记录,研究或监控应用程序或远程设备的控制提供了有效和安全的方法。
