    • Disclosed is a geometric puzzle comprising a plurality of three-dimensional components of at least one type, each component of the same type being derived by notionally dividing a fundamental shape into a plurality of equal parts, said fundamental shape being selected from the group consisting of a regular tetrahedron having edges of equal length and a regular pyramid with a square base and also having edges of equal length, said components being capable of assembly into multiple composite shapes. Each component may be equal and identical to one another or each pair of components may comprise mirror images of one another. Surfaces of said components may be provided attractive magnetic elements to hold said components in a composite shape.

    • In an OCT apparatus, an object light beam is returned from a target and interferes with a reference light beam. Image information is obtained from a depth Z in the target that depends on the optical path difference between the object and reference beams with a resolution that depends on the coherence length of the light. A scanner transversely scans the target with the object beam over a plurality of image points defined by the resolution of the apparatus. Interface optics directs the reference and object beams onto an array of detector elements such that the optical path difference between the reference beam and the object beam varies across the array. The reference beam and the object beam interfere with each other over the array of detector elements for individual image points on the target during each transverse scan. A memory stores a subset of data points corresponding to each individual image point obtained from each detector elements of the array. A processor processes one or more of the subsets of data points to derive image information extending over a range of depths in the target for each individual image point. The obtained image information is displayed on a displace device.
    • 在OCT设备中,物体光束从目标返回并干扰参考光束。 图像信息从目标中的深度Z获得,其取决于取决于光的相干长度的分辨率的对象和参考光束之间的光程差。 扫描仪在由装置的分辨率限定的多个图像点上用对象光束横向扫描目标。 接口光学器件将参考光束和物体光束引导到检测器元件的阵列上,使得参考光束和物体光束之间的光程差在阵列上变化。 参考光束和物体光束在每个横向扫描期间在目标上的各个图像点的检测器元件阵列上彼此干涉。 存储器存储对应于从阵列的每个检测器元件获得的每个单独图像点的数据点的子集。 处理器处理数据点的一个或多个子集以导出在每个单独图像点的目标中的深度范围上延伸的图像信息。 获得的图像信息显示在位移装置上。

    • The invention pertains generally to the field of psychotropic drug discovery and neuroscience. More specifically, the invention refers to a device that allows the long-term stimulation of cultured neurons grown on a silicon die, thereby replacing the use of intact animal models. The device consists of a controlled sterile environment in which the neuronal cultures can grow, and into which specific candidate compounds (e.g., psychotropic drugs) are added. During the period of growth, which can be extended for months, specifically tailored patterned activity can be applied to the neuronal network, simulating the activity normally found in a brain. The neuronal networks are grown on a silicon surface which is targeted by a light source, which functions to alter the connectivity of the surface below a specific group of cells. Cells on this targeted region are caused to fire on a brief electrical pulse. Upon completion of the growth period the silicon die can be removed and subject to electrophysiological and biochemical analysis.
