Abstract: Optical scanning of barcode symbols is carried out first in an aim mode wherein the symbol is scanned using a first scan pattern that is relatively small and dense so as to be visible to the user, and thereafter using a second, larger, more robust scan pattern for decoding. The preferred scanner module has a scanner mirror which is mounted to a bracket by way of a leaf spring, allowing the mirror to oscillate in one direction. This is hung from a stationary chassis by means of two strips of mylar film, which are themselves protected against mechanical shock by pins which pass through holes in the bracket. The pins provide accurate alignment of the bracket with respect to the chassis.

Abstract: Location of a mobile unit is determined by a combined probability, derived from a first probability for possible locations based on a current sample of radio signal characteristics and a second probability that a unit has moved from a prior location or probable location to each possible location.
Abstract translation: 移动单元的位置由基于当前无线电信号特征样本的可能位置的第一概率导出的组合概率和单元已经从先前位置或可能位置移动到每个可能位置的第二概率来确定。

Abstract: A method and apparatus for imaging targets with an imaging reader. The method includes: operatively connecting an application specific integrated circuit (ASIC) to the solid-state imager to receive the image data from the solid-state imager and generating a stream of combined data frames by the ASIC. A combined data frame in the stream generated by the ASIC including an image frame from the image data and a header. The method also includes receiving and processing the stream of combined data frames from the ASIC at a controller operatively connected to the ASIC.
Abstract translation: 用成像阅读器成像目标的方法和设备。 该方法包括：操作性地将专用集成电路（ASIC）连接到固态成像器，以从固态成像器接收图像数据并且由ASIC生成组合数据帧的流。 由ASIC生成的流中的组合数据帧包括来自图像数据的图像帧和标题。 该方法还包括在可操作地连接到ASIC的控制器处接收和处理来自ASIC的组合数据帧的流。

Abstract: A system for locating mobile units in a data communications system based on signal strength measurements of mobile unit transmissions is calibrated for variations in mobile unit transmitter power by determining range of a mobile unit from an access point using two way time ranging. The time ranging is compared to the value for range based on signal strength and a correction value for the mobile unit is updated based on the difference between range based on time ranging and the range based on signal strength.
Abstract translation: 基于移动单元传输的信号强度测量，在数据通信系统中定位移动单元的系统通过使用双向时间范围从接入点确定移动单元的范围来校准移动单元发射机功率的变化。 将时间范围与基于信号强度的范围值进行比较，并且基于基于时间范围的范围与基于信号强度的范围之间的差异来更新移动单元的校正值。
