    • An expansion card with an integrated fingerprint acquisition system is provided hat is able to be connected to a portable computer. In one aspect of the invention, CMCIA standards are used for the expansion card. The expansion card is built such the fingerprint acquisition system is on a slidable carriage which may extend out from the expansion card housing, or may be retracted into the housing when the fingerprint acquisition system is not in use. A locking mechanism keeps the carriage in the retracted position, and a spring provides the force necessary to slide the carriage into the extended position when pressure is placed on the slidable carriage. An advantage of the invention is that the fingerprint recognition device is small enough to fit within a PCMCIA standard expansion card. Another advantage of the invention is that the fingerprint recognition system, when not in use, is enclosed within a portable computer's housing such that the invention does not use additional desk space in addition to the portable computer itself, other than that necessary for the retractable access portion to extend into an extended position.
    • 提供了具有集成指纹采集系统的扩展卡,帽子能够连接到便携式计算机。 在本发明的一个方面,CMCIA标准用于扩展卡。 扩展卡被构建,使得指纹采集系统位于可从扩展卡壳体延伸出的可滑动的托架上,或者当指纹采集系统不使用时可以缩回到外壳中。 锁定机构将托架保持在缩回位置,并且当压力被放置在可滑动的托架上时,弹簧提供将滑架滑动到伸出位置所需的力。 本发明的一个优点是指纹识别装置足够小以适合PCMCIA标准扩展卡。 本发明的另一个优点在于,指纹识别系统在不使用时被封装在便携式计算机的外壳内,使得本发明除了便携式计算机本身之外还不使用额外的桌面空间,而不是可伸缩存取所必需的 部分延伸到延伸位置。

    • A compact-sized fingerprint imaging device includes an optical plate for creating a fingerprint pattern at a finger field on the optical plate. The fingerprint pattern is illuminated with light from an illuminating tool to create imaging light rays. A small thickness of the optical plate, and hence of the fingerprint imaging device, is possible due to a design that includes an array of microreflectors covering a part of the optical plate, the microreflectors being distributed along a base surface. The imaging light rays from the fingerprint pattern that are reflected by the array of microreflectors are received by an imaging lens that projects an image of the fingerprint pattern to an image sensor.
    • 小型尺寸的指纹成像装置包括用于在光学板上的手指区域处产生指纹图案的光学板。 指纹图案用来自照明工具的光照射以产生成像光线。 由于包括覆盖光学板的一部分的微反射器的阵列的设计,可以使光学板的厚度以及因此的指纹成像装置的小厚度,微反射器沿着基底表面分布。 由微反射体阵列反射的来自指纹图案的成像光线由将指纹图案的图像投射到图像传感器的成像透镜接收。
