    • An optical code reading system having an auto-exposure system for use with a variable resolution imaging sensor in which very low resolution images are used to determine exposure parameters is presented. The very low resolution images can be transferred much faster than high resolution images which results in a very fast auto-exposure system. The optical code reading system further includes an optical zoom system for zooming in and out of a target without the use of any moveable components. The optical zoom system makes use of a binning and/or subsampling feature of the imaging sensor for zooming in and out of the target. High-speed decoding methodologies are also presented for the optical code reading system. One decoding methodology utilizes low resolution images for performing high-speed decoding. Other methodologies utilize low resolution images and higher resolution images, if the optical code imaged by the low resolution images is not decoded successfully.
    • 本发明提供一种具有自动曝光系统的光学代码读取系统,该自动曝光系统与可分辨率成像传感器一起使用,其中使用非常低分辨率的图像来确定曝光参数。 非常低分辨率的图像可以比高分辨率图像传输得更快,这导致非常快的自动曝光系统。 光学代码读取系统还包括用于在不使用任何可移动部件的情况下放大和缩小目标的光学变焦系统。 光学变焦系统利用成像传感器的分档和/或子采样特征来放大和缩小目标。 还提供了用于光学代码读取系统的高速解码方法。 一种解码方法利用低分辨率图像进行高速解码。 如果由低分辨率图像成像的光学代码未成功解码,则其他方法利用低分辨率图像和较高分辨率的图像。

    • A method and apparatus for implementing alerts on a browser running on a portable handheld device is disclosed. The method generates an asynchronous notification action from the server and in response transmits an alert containing a message indicating availability of HTML pages that describe the nature of the alert. The alert is received at a node on a network and translated into the original message. An alert receipt acknowledgment is transmitted to the server. Access to the alert HTML page is provided through a URL containing the appropriate query strings necessary to present the appropriate HTML page. The invention also discloses a wireless local area network (WLAN) adapter associated with a wireless network that receives paging signals from a server on the network and returns an acknowledgment signal back to the server. The invention also discloses a client/server based method of delivering messages initiated by a client. After a connection is established between a client and server, the client requests a message from the server. In response, the server retrieves and returns the message back to the client.

    • An automatic focusing system for an imaging-based bar code reader. The automatic focusing system employs a two step process for moving a lens of an imaging system along its path of travel such that a sharp image of a target bar code is projected or focused onto an imaging system pixel array. The first step is laser ranging which utilizes a laser beam for range finding. Laser ranging determines a distance between the imaging system pixel array and the target bar code. Given the determined distance, the automatic focusing system moves the lens to a suitable position for imaging the target bar code. If ambient conditions prevent laser ranging from properly working, the second step is focus analysis. Focus analysis involves moving the lens in accordance with a search routine and analyzing image frames of the target object to find a suitable focus position.
    • 一种用于基于成像的条码阅读器的自动对焦系统。 自动对焦系统采用两步法,沿着其行进路线移动成像系统的透镜,使得目标条形码的清晰图像投影或聚焦到成像系统像素阵列上。 第一步是使用激光束进行测距的激光测距。 激光测距确定成像系统像素阵列与目标条形码之间的距离。 给定确定的距离,自动聚焦系统将镜头移动到合适的位置,用于对目标条形码进行成像。 如果环境条件阻止激光测距正常工作,第二步就是焦点分析。 焦点分析涉及根据搜索程序移动镜头并分析目标对象的图像帧以找到合适的焦点位置。
