    • A wireless input device may negotiate a predefined transmit/receive schedule with a receiving device (i.e., PC, PDA, cellular device). To conserve power, the wireless components of the input device are powered down during periods of non-transmission. The wireless input device detects intermediate user input and corresponding data according to a detection rate during periods of non-transmission. The intermediate data is then transmitted to the receiving device during a transmission period along with a current data detected at the time of transmission. The wireless device may further discard any intermediate data which does not reflect a significant change. Additionally, the system and method may include a detection rate that adapts to degrees of user activity detected by the wireless input device.
    • 无线输入设备可以与接收设备(即PC,PDA,蜂窝设备)协商预定义的发送/接收调度。 为了节省功率,输入设备的无线组件在不传输期间被关闭。 无线输入设备在非传输期间根据检测率检测中间用户输入和对应数据。 然后在发送期间将中间数据与发送时检测到的当前数据一起发送给接收装置。 无线设备可以进一步丢弃任何不反映重大变化的中间数据。 此外,系统和方法可以包括适应由无线输入设备检测到的用户活动程度的检测率。

    • A method is described for the reading of a bar code consisting of a predetermined number of code elements for the generation of a binary signal with sequential high and low phases, the lengths of which correspond to the width of the sequential code elements, in particular with a reading direction extending obliquely to the code elements. The code elements are sensed by one or more sensing beams of a bar code reader along scanning lines extending substantially parallel to one another, with each region of a code element scanned by a scanning line forming a code element section. For substantially each scanning line those code segments which consist of a code element section, or a plurality of sequential code element sections, are detected, which are recognized as permissible code segments on the basis of preset decision criteria. A reference code element is found from mutually associated code element sections, each representing the same code element of the bar code for different scanning lines, and the binary signal is produced from the reference code elements. Furthermore, an apparatus is described for carrying out the method.
    • 描述了一种用于读取由预定数量的代码元素组成的条形码的方法,用于产生具有连续高和低相位的二进制信号,其长度对应于顺序码元素的宽度,特别是与 读取方向倾斜地延伸到代码元素。 代码元素由条形码阅读器的一个或多个感测光束沿着基本上彼此平行延伸的扫描线感测,码元的每个区域由扫描线扫描形成代码元素部分。 对于基本上每个扫描线,检测由代码元素部分或多个顺序代码元素部分组成的代码段,其基于预设的判定标准被识别为可允许的代码段。 从相互关联的代码元素部分找到参考代码元素,每个代码元素段代表不同扫描行的条形码的相同代码元素,并且从参考代码元素产生二进制信号。 此外,描述了用于执行该方法的装置。
