摘要： A frame (2) for an image such as a picture (12) is formed from a microlens array. Such an array produces an apparent optical plane which is not coplanar with the real plane of the array. This produces the visual effect of the picture (16) being divorced from the frame (2) and an illusion of depth is created as between the frame (2) and the picture (16).
摘要翻译：用于诸如图像（12）的图像的帧（2）由微透镜阵列形成。这种阵列产生与阵列的实际平面不共面的表观光学平面。这产生了与帧（2）离散的图像（16）的视觉效果，并且在帧（2）和图像（16）之间产生深度错觉。

摘要： A method of addressing a matrix of ferroelectric liquid crystal cells involving the blanking of all lines of pixels within the display prior to addressing with information for display. The blanking pulse (16) has a lower amplitude (Vs/m) and a longer duration (mt) than the select pulse (12). By reducing the amplitude of the blanking pulse (16), it may be applied to a given line at or below eight lines before the necessary select pulse (12) is applied in order to display information. This has the effect of maximising the display brightness and reducing flicker.
摘要翻译：一种在用寻址信息进行寻址之前，涉及在显示器内消隐所有像素线的铁电液晶单元矩阵的寻址方法。消隐脉冲（16）具有比选择脉冲（12）更低的振幅（Vs / m）和更长的持续时间（mt）。通过减小消隐脉冲（16）的幅度，可以在施加必要的选择脉冲（12）之前将其施加到八行或其下方的给定行以便显示信息。这具有最大化显示亮度并减少闪烁的效果。

摘要： A direct fingerprint image is formed by illuminating a transparent planar substrate (22) from one surface (26) with collimated light (20), the substrate (22) having pressed against the other surface (28) a fingerprint (30) to be imaged. Light striking the surface (26) against which ridges of the fingerprint (30) are in contact undergoes total internal reflection within the substrate (22) and causes a direct image of the fingerprint to be formed by generating fluorescent light within a planar fluorescent member (38).

摘要： A segment of a given signal is aligned with a corresponding reference segment by passing the reference segment through a full-wave rectifier (8), an anti-alias filter (10) and a first sampler (9), and storing the result in a first register (19). The output of the first sampler (9) is moreover passed through a second anti-alias filter (12) and a second sampler (13) which samples at a lower rate, and the result is stored in a second register (21). The given signal is then subjected to the same process with the exception that the output signals of the first (9) and second (13) samplers are passed continuously through first (23) and second (25) shift registers respectively until a correlator (40) indicates at least a predetermined degree of correlation between the contents of the second register (21) and the second shift register (25). A sliding correlation is then performed between the contents of the first register (19) and the first shift register (23) to determine the position of the correlation peak. The alignment process may be used when it is required to compare a segment of an audio signal recorded on a magnetic tape with the corresponding segment recorded on a master tape.
摘要翻译：通过使参考段通过全波整流器（8），抗混叠滤波器（10）和第一采样器（9）将给定信号的段与相应的参考段对准，并将结果存储在第一次登记（19）。此外，第一采样器（9）的输出通过第二抗混叠滤波器（12）和以较低速率采样的第二采样器（13），并将结果存储在第二寄存器（21）中。然后给定信号进行相同的处理，除了第一（9）和第二（13）采样器的输出信号分别连续通过第一（23）和第二（25）移位寄存器，直到相关器（40））表示第二寄存器（21）和第二移位寄存器（25）的内容之间的至少预定的相关程度。然后在第一寄存器（19）和第一移位寄存器（23）的内容之间执行滑动相关，以确定相关峰值的位置。当需要将记录在磁带上的音频信号的片段与记录在母带上的相应片段进行比较时，可以使用对准过程。

摘要： A mass-spectrometer comprises an ionisation chamber (4) and an electrode cell (10) for preferentially accelerating ions having a predetermined velocity towards a target electrode (12). The cell (10) comprises four serially arranged apertured electrodes (A, B, C, D) which are energized by an energization voltage generator (61). The generator (61) supplies a variable ion-attracting bias voltage to the first electrode (A) and periodic voltage waveforms, relative to the first electrode bias voltage, to the other electrodes (B, C, D), these waveforms all having the same period. At the start of each period the second and fourth electrodes (B and D) are supplied with a short ion-attracting voltage pulse. During each period the third electrode (C) is supplied with a voltage waveform which starts at an ion-repelling voltage V2 and ends at an ion-attracting voltage V2 and passes from one to the other via a step to an ion-repelling voltage V2/2, a linear ramp from this to an ion-attracting voltage V2/2, and a step from this to the ion-attracting voltage V2.

摘要： An optical modulation device includes first (1, 4, 6) and second (2, 5, 7) optically transmissive parallel plates having a ferroelectric liquid crystal material sandwiched between them. A plurality of spacer members (10), each secured to one of the plates, are located between the plates to maintain the plate spacing. The spacer members form walls defining parallel liquid crystal material-containing channels (11) which extend parallel to the plates. These channels communicate along their lengths with cavities (12) at least partly defined by the spacer members (10). These cavities may be created by segmenting each wall, the separations between the successive segments constituting the respective cavities. Alternatively, each wall (14) may be provided with a parallel auxiliary wall (10) of lesser height close to it but spaced from it, the space between the two walls forming a cavity.
