    • A fluid handling system for transferring fluids is disclosed. The fluid handling system incorporates a plurality of transfer units for dispensing and/or collecting fluids as part of a closed analytical system. The plurality of transfer units are capable of functioning independently and/or collectively when assembled in a unitary array format. Methods of making and using the fluid handling system are also disclosed. The fluid handling system allows a sub-array of transfer units to shift in a vertical direction independent from a position of another sub-array of transfer units that are assembled within the same fluid head. Therefore, the fluid handling system facilitates multi-port fluid delivery and collection in an array format. Further, the fluid handling system aligned with a sensing surface enables label-free detection assays to be performed in an analytical system.
    • 公开了一种用于输送流体的流体处理系统。 流体处理系统包括用于分配和/或收集流体作为封闭分析系统的一部分的多个转运单元。 当以单一阵列格式组装时,多个传送单元能够独立地和/或共同地起作用。 还公开了制造和使用流体处理系统的方法。 流体处理系统允许传送单元的子阵列在垂直方向上移动,独立于组装在同一流体头内的另一传送单元子阵列的位置。 因此,流体处理系统便于以端口流体输送和以阵列格式收集。 此外,与感测表面对准的流体处理系统使得能够在分析系统中进行无标记检测分析。

    • A method and modem for communicating serial input data over a transmission link. Serial input data is partitioned into parallel data elements prior to rotation by an invertible linear mapping. Resulting frames of parallel signal elements sequentially modulate a carrier, which is then transmitted over the link. After receipt of the modulated carrier from the link, the signal is demodulated and assembled into frames of parallel signal elements which are derotated by an inverse linear mapping. Thresholding the result of the inverse mapping recovers the parallel data elements, which are then re-assembled into serial output data. The linear mapping employs: 1) commuting rotation matrices for convolutionally rotating data vectors into signal vectors and vice-versa; 2) filter bank polyphase rotation matrices; or 3) computationally efficient multi-rate wavelet filter banks. Transmitter pre-emphasis places most of the information in lower baseband frequencies; complimentary de-emphasis occurs in the receiver. Logarithmic amplification of the baseband signal prior to carrier modulation improves modulation gain and transmit channel noise attenuation. Coefficients of the rotation matrix of the receiver are adaptively equalized to correct for transmission path distortion. FM double-side band is employed in systems requiring minimized cost and complexity. FM single-side band is employed in systems in which bandwidth reduction is desirable. AM is also employable.
    • 一种用于通过传输链路传送串行输入数据的方法和调制解调器。 串行输入数据在通过可逆线性映射旋转之前被划分为并行数据元素。 并行信号单元的所得帧顺序地调制载波,然后通过链路发送。 在从链路接收到调制载波之后,该信号被解调并组合成并行信号元素的帧,其被反向线性映射解旋。 对逆映射的结果进行阈值恢复并行数据元素,然后将其重新组合成串行输出数据。 线性映射采用:1)将卷积旋转数据向量的旋转矩阵换成信号向量,反之亦然; 2)滤波器组多相旋转矩阵; 或3)计算效率高的多速率小波滤波器组。 发射机预加重将大部分信息置于较低的基带频率; 在接收机中发生免费去加重。 载波调制之前的基带信号的对数放大提高了调制增益和发射信道噪声衰减。 接收机的旋转矩阵的系数被自适应地均衡以校正传输路径失真。 FM双边带用于需要最小化成本和复杂性的系统中。 FM单边带用于需要带宽降低的系统中。 AM也可以使用。
