摘要： An automatically-activated wireless code symbol reading system comprising a hand-supportable housing having a manually-activatable data transmission switch under automatic communication range dependent control. When a bar code symbol is read, the bar code reader is located inside the predetermined RF data communication range of the system, then the symbol character data string, produced at substantially the same time as the manual activation of the data transmission switch, is transmitted to the base station over the wireless RF communication link. If the device is outside the range, then an audible and/or visual indication is automatically generated, and the packaged symbol character data string is packaged and transmitted to a data storage buffer aboard the bar code reader. Then when the bar code symbol reader is moved within the communication range of the system, the buffered/packaged symbol character data is automatically transmitted to the base station by the RF-based data communication link.

摘要： The wireless PDT of the present invention employs a "display-on bottom" design which places the unit perfectly centered in the hand of the operator, allowing for the best possible viewing as well as providing comfortable single-handed operation. The high-resolution LCD display allows the PCT to show sharp, clear bitmap images while supporting all Windows-recognized font types and sizes. With the auto back-lit feature, the brightness adjusts automatically making the screen easy to read in all light conditions. The PDT is designed for support within the download/charger cradle of a base station which interfaces with a host system using either USB or RS232 interface. Two standard 'AA' or rechargeable Li-Ion batteries provide more than 100 hours of operation. In addition, the PDT comes standard with 2MB of RAM providing enough memory to store over 100,000 records.
摘要翻译：本发明的无线PDT采用“底部显示”设计，其将单元完美地置于操作者的手中，从而可以最好地观看以及提供舒适的单手操作。高分辨率LCD显示屏允许PCT显示清晰，清晰的位图图像，同时支持所有Windows识别的字体类型和尺寸。使用自动背光功能，亮度自动调节，使屏幕在所有光线条件下都易于阅读。 PDT设计用于在使用USB或RS232接口与主机系统连接的基站的下载/充电器支架中进行支持。两个标准“AA”或可充电锂离子电池提供超过100小时的操作。此外，PDT标配2MB内存，提供足够的内存来存储超过100,000条记录。

摘要： An improved bar code symbol reading methodology, device, and system includes a bar code symbol reading engine (151’) that reads bar code symbols affixed to objects proximate thereto and produce symbol character data representative of such bar code symbols. A data transmission subsystem (523), operably coupled to the bar code reading engine, communicates such symbol character data to the communication interface of a host system over a communication link therebetween. The data transmission subsystem (523) implements a plurality of different communication interfaces (551A, 551B). During an interface configuration mode of operation, the data transmission subsystem (523) automatically cycles through at least one of the plurality of different communication interfaces whereby, for a given communication interface, the data transmission subsystem selectively activates the given communication interface - while disabling the other communication interfaces, and tests the communication link between the given communication interface and the host system to ascertain if the given communication interface corresponds to the communication interface of the host system.

摘要： An improved bar code symbol reading methodology, device,and system includes a bar code reading engine that reads bar code symbols affixed to objects proximate thereto and produces symbol character data representative of such bar code symbols. A data transmission subsystem, operably coupled to the bar code reading engine, communicates such symbol character data to the communication interface of a host system over a communication link therebetween. The data transmission subsystem implements a plurality of different communication interfaces. During an interface configuration mode of operation, the data transmission subsystem automatically cycles though at least one of the plurality of different communication interfaces whereby, for a given communication interface, the data transmission subsystem selectively activates the given communication interface (while disabling the other communication interfaces) and tests the communication link between the given communication interface and the host system to ascertain if the given communication interface corresponds to the communication interface of the host system. Upon detecting that the given communication interface corresponds to the communication interface of the host system, the interface configuration mode of operation ends, thereby enabling subsequent data communication between the bar code symbol reading device and the host system over the active communication interface. In this manner, the data transmission subsystem is able to automatically configure itself such that its interface is suitable for communication to the communication interface of the host system. Moreover, the device is thus capable of interfacing to a variety of different host devices in an automatic and error free manner with minimal human involvement, thus providing significant advantages over the prior art bar code symbol reading devices. Preferably, the interface configuration mode of operation is carried out when the device is initially powered up. The communication interfaces implemented by the data transmission subsystem of the device and the communication interface of the host system may support a plurality of different data communications links, including wireless data links (such an infra-red link, a Bluetooth RF link, and an IEEE 802.11b RF link), wired serial data links (such as a keyboard wedge link, an RS-232 link, USB link, an IEEE 1394 link, an RS-422 link, and a RS-485 link) or other standard data links (such as an OCIA link, an IBM 46XX link, a Light Pen Emulation link, and a LTPN link).
