A wireless code symbol reading system including a wireless hand-supportable code symbol reader in two-way RF communication with a base station operably connected to a host system, by way of an RF-based wireless data communication link having a predetermined RF communication range over which two-way communication of data packets can occur. The wireless hand-supportable code symbol reader is programmed to automatically detect when it is located inside and outside of the predetermined RF communication range. When the wireless reader is inside the RF communication range, then symbol character data is automatically transmitted to the base station, and when the wireless reader is located outside of the RF communication range, then symbol character data is automatically collected and stored in a data packet buffer, until the wireless reader has re-entered its RF communication range.

Wireless code symbol reading system with automatic communication range dependent control

A wireless automatically-activated bar code symbol reading system for use in a work environment, the system including a device controller programmed to automatically detect when a wireless hand-supportable bar code symbol reader is located inside of a predetermined RF communication range based on measuring the strength of a detected reference signal, and thereupon to automatically transmit to a first RF-based transceiver, the symbol character data string produced while the wireless hand-supportable bar code symbol reader is located inside of the predetermined RF communication range. Also, the device controller is programmed to automatically detect when the wireless hand-supportable bar code symbol reader is located outside of the predetermined RF communication range based on measuring the strength of the detected reference signal, and thereupon to automatically collect and store in the data packet group buffer, the symbol character data string produced while the wireless hand-supportable bar code symbol reader is located outside of the predetermined RF communication range.

Automatically-activated wireless hand-supportable laser scanning bar code symbol reading system with automatic communication range dependent control

An automatically-activated laser scanning 2-D bar code symbol reading system employing a visible linear-type laser scanning pattern and an audible feedback signal during scan data capturing and buffering operations. The system includes a laser scanning 2-D bar code symbol reading mechanism that automatically produces a visible linear-type laser scanning pattern for scanning a 2-D bar code symbol structure on an object as its hand-supportable housing is manually transported past a 2-D bar code symbol along a height-wise direction by an operator, automatically capturing lines of scan data from the scanned 2-D bar code symbol structure, decode processing the scan data, and generating a symbol character data string representative of the read 2-D bar code symbol.

A wireless automatically-activated bar code symbol reading system having a wireless hand-supportable bar code symbol reader in two-way RF communication with a base station, by way of an RF-based wireless data communication link having a predetermined RF communication range. A manually-operated data transmission activation switch is integrated with the hand-supportable housing, for generating a data transmission control activation signal in response to the activation of the data transmission switch within a first predetermined time period. A device controller is programmed to automatically detect when the wireless reader is located inside of the predetermined RF communication range, and thereuponautomatically transmit to a first RF-based transceiver, the symbol character data string produced at substantially the same time when the data transmission control activation signal is generated while the wireless reader is located inside of the predetermined RF communication range.

Wireless bar code symbol reading system having hand-supportable unit and remote base station

Disclosed is an automatically-activated wireless code symbol reading system comprising a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner. Each time the scanned bar code symbol is successfully read during a bar code symbol reading cycle, a new bar code symbol character string is produced, while an indicator light on the hand-supportable housing is actively driven. During the bar code symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a currently or subsequently produced symbol character data string to be automatically selected and transmitted to the host system. By virtue of the present invention, automatically-activated hand-supportable bar code symbol readers are now able to accurately read, in an unprecedented manner, bar code symbols on bar code menus, consumer products positioned in crowded point-of-sale environments, and other objects requiring automatic identification and/or information access.

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.

When the wireless bar code symbol reader is located inside of the predetermined RF communication range based on measuring the strength of the detected reference signal, it automatically transmits to the base station, the symbol character data string produced while the reader is located inside of the predetermined RF communication range. When the wireless reader is located outside of the range, based on measuring the strength of said detected reference signal, the reader automatically collects and stores the symbol character data string produced during that time.
