    • A maintenance assembly and method for insulating printer/copier solid ink printheads. The maintenance assembly includes a car movably supported for travel along a maintenance path interposed between a first printhead and an ink receiving surface from a home position to a completion position and a wiper extending from the car for wiping the printhead front faces as the car moves along the path. The method includes moving a car having a wiper extending therefrom along a maintenance path interposed between the printhead front faces and the ink receiving surface parallel to the front faces for wiping the first and second printhead front faces.

    • A pachymeter apparatus for measuring corneal thickness is configured for the calculation of intraocular pressure (“IOP”). The apparatus includes a pachymeter for measuring corneal thickness as well as a microprocessor and a user interface. A reading of IOP from a tonometer can be entered into the device and corrected according to the pachymeter reading of corneal thickness. Correction algorithms are user selectable and user customizable. A pachymeter may have a graphical display which displays multiple locations at which measurements are to be taken. A pachymeter may use a capacitor charged by a variable current supply to measure times for signals to be reflected from a back side of a cornea.

    • A planar magnetic acoustical transducer including a diaphragm with electrical circuit carrying conductors having a width substantially equal to a combined width of a plurality of magnetic fields created by equally spaced opposing rows of permanent magnets carried by opposing frame sections between which the diaphragm is mounted such that substantially the entire active area of the diaphragm is driven to create a smooth frequency response. The electrical circuit includes generally parallel segments which are aligned within the magnetic fields created by the rows of opposing magnets and are spaced at a distance relative to one another generally not less than a distance equal to a width of pole elements which are integrally formed with the frame sections and which pole elements are spaced intermediate each of the rows of magnets so as to be in an opposing relationship with one another on opposite sides of the diaphragm.

    • A method and apparatus for document verification exploits a temporally variable physical process to generate a reproducible effect that cannot be copied. A document such as a credit card is provided with a spot or stripe that incorporates at least one, and preferably a large plurality of photorefractive crystals arrayed in a random manner. The document verifying apparatus includes a coherent light source such as a diode laser to illuminate the photorefractive crystals, and a photosensor to receive light scattered from the photorefractive crystals. The random distribution and orientation of photorefractive crystals comprises a unique characteristic for each card or document, and this characteristic is not based on any assigned number or code. The response of photorefractive crystals to the coherent illumination comprises a time-varying characteristic that is dependent upon the intensity and temporal nature of the illumination itself. Input to the laser illuminator may be varied to elicit differing responses from the photorefractive crystals, and this factor may be very difficult for a counterfeiter to ascertain. Also, for any given illumination intensity or temporal pattern, the image received by the photosensor varies with time. The time at which the photosensor signal is sampled to obtain an identifying image may also be varied, thereby further compounding the difficulty for a counterfeiter to overcome. A large number of "snapshots" of the time-varying image of the document is electronically captured, digitized, and stored in an electronic media. The photosensor signal is compared to the stored data; a match indicates a valid document, and no match indicates an invalid or unauthorized document. The image recognition process can be enhanced by comparing the rate of change in a sequence of images elicited by the laser illuminator.
    • 用于文件验证的方法和装置利用时间上可变的物理过程来产生不可复制的可再现效果。 诸如信用卡的文件被提供有点或条纹,其包含以随机方式排列的至少一个,优选大量的光折变晶体。 文件验证装置包括诸如用于照射光折射晶体的二极管激光器的相干光源和用于接收从光折射晶体散射的光的光电传感器。 光折射晶体的随机分布和取向包括每个卡或文件的唯一特性,并且该特征不基于任何分配的数字或代码。 光折射晶体对相干照明的响应包括取决于照明本身的强度和时间性质的时变特性。 可以改变对激光照射器的输入以引起与光折射晶体的不同响应,并且这个因素对于伪造者来说可能是非常困难的。 此外,对于任何给定的照明强度或时间图案,由光电传感器接收的图像随时间变化。 光传感器信号被采样以获得识别图像的时间也可以变化,从而进一步增加了伪造者克服的难度。 文档的时变图像的大量“快照”被电子捕获,数字化并存储在电子媒体中。 将光电传感器信号与存储的数据进行比较; 匹配表示有效的文档,没有匹配表示无效或未经授权的文档。 可以通过比较由激光照明器引发的图像序列的变化率来增强图像识别过程。
