    Abstract: A shutter section includes a stack of circular plates independently rotatable in a nest formed as a laminar formation of rings. The plates have central openings defining a light path. Four central plates in the stack are shutter guide plates with radial guide slots slideably holding shutter blades. Two outer pairs of plates are shutter drive plates connected by cams to the shutter blades. Simultaneous rotation of a shutter guide plate and associated shutter drive plate causes rotation of an associated shutter blade around the light path. Rotation of a shutter drive plate while the associated shutter guide plate is stationary causes the cam to move the associated shutter blade radially. The nest is enclosed by end plates. A motor section has motors driving pinions to rotate the circular plates. The circular plates, rings pinions and shutter blades are made of sheet metal. Shutters may be provided as interleaved pairs each driven by a pair of rotatable drive plates.

    Abstract: Associative retrieval of data via the technique of superimposed code words is accomplished by circuitry which automatically generates the codes, and which searches through stored code words to find the ones that match a given query code. Code generation is performed using pseudo-random techniques that are reproducible, obviating the need for a pre-prepared code dictionary. Identification of the codes that meet a match requirement is accomplished by logically AND'ing selected bits from the stored codes, said selection being determined by the query code.

    Abstract translation: 通过叠加代码字技术的数据关联检索是通过自动生成代码的电路实现的,并且通过存储的代码字进行搜索以找到与给定查询代码相匹配的代码字。 使用可再现的伪随机技术来执行代码生成,从而避免了对预先准备好的代码字典的需要。 符合匹配要求的代码的识别是通过逻辑地将来自存储的代码的所选位进行逻辑“和”来实现的,所述选择由查询代码确定。

    Abstract: The random cell scintillations which have been observed in animated dithered displays are substantially eliminated by establishing a hysteresis band about the dither threshold value assigned to each display cell. The hysteresis band is delimited by upper and lower dither threshold values. Determination of whether the intensity of each picture element of the image to be displayed is to be compared to the upper or the lower threshold value assigned to the corresponding display cell is made based on the current state of the cell.

    Abstract translation: 通过建立关于分配给每个显示单元的抖动阈值的滞后带,基本上消除了在动画抖动显示中观察到的随机单元闪烁。 滞后带由上限和下限抖动阈值界定。 基于小区的当前状态,确定要显示的图像的每个像素的强度是否与分配给相应显示单元的上限阈值或下阈值进行比较。

    Abstract: A protractor comprising a frame and a lever arm coupled thereto. The frame includes a first substantially straight edge and an elongate track adjacent to the first edge. The lever arm includes a second substantially straight edge and a channel which mateably engages the track of the frame. The channel/track combination couples the lever arm to the frame and permits the lever arm to rotate about an axis substantially orthogonal to the first and second edges. The first and second edges intersect at a point allowing a user to describe an angle between the two edges.
