Battery power consumption and data transfer latency of an electro-optical reader in a wireless network are minimized by turning a radio off in a default state, and by turning the radio on only after the reader has generated data to be transferred along the network.

Method of and arrangement for minimizing power consumption and data latency of an electro-optical reader in a wireless network

Techniques are provided for frequency coordination among two different wireless network protocols, such as the IEEE 802.11 and Bluetooth protocols, operating in proximity with one another. Coordination is accomplished by the use of a first radio transceiver operating in accordance with a first communication protocol (which may be the 802.11 protocol) and using a frequency band (which may be the 2.4 GHz band), a base station connected to a wired network and operating in accordance with the first communication protocol, a second radio transceiver operating in accordance with a second communication protocol (which may be the Bluetooth protocol) and using the frequency band, and a coordinator associated with the base station for, in turn, activating the first radio transceiver, deactivating the first radio transceiver, activating the second radio transceiver, and deactivating the second radio transceiver.

Coexistence techniques in wireless networks

A signaling arrangement and method for use in a wireless local area network managed by a system manager include a reader for electro-optically reading bar code symbols. The system manager verifies that a symbol has been successfully read and sends an acknowledgment signal by wireless, radio frequency transmission to a remote indicator operative for generating an alert signal noticeable to a user.

Signaling arrangement for and method of signaling in a wireless local area network

A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.

A universal interface system for use with a data acquisition system including a data acquisition device such as a bar code scanner or scanner integrated terminal for providing digital data signals indicative of acquired data for transmission to a host device such as a computer, and a host device having host-specific input/output data format requirements. The universal interface system comprises universal data exchange means located in the data acquisition device for providing digital data signals in a universal data exchange format independent of the data format requirements of the host device; and a host interface cable coupled to the data acquisition device and to said host device, for transmitting acquired digital data from the data acquisition device to the host device, the interface cable comprising means for translating digital data from the universal data exchange format to the host-specific input/output data format requirements. The interface cable comprises a buffer for storing a host parameter data word used in communications with the host device. The universal data exchange means comprises a memory for storing a plurality of host parameter data words, each of the host parameter data words being associated with one of a plurality of different host interface modules; and means for reading from the memory and transmitting to the host interface module the host parameter data word associated with the particular host interface module operatively connected thereto.

Universal host interface for data acquisition systems

A scanner interface is operatively connected to an electro-optical scanner for scanning bar code symbols. A status/condition interface is operatively connected with a system component, e.g., a photodetector, a decoder, a battery, etc., whose status/condition is to be monitored. Threshold information about the system component is stored in a memory. A system processor generates updated information about the system component during scanning, compares the updated information with the threshold information and generates an output signal upon such comparison. In response to the output signal, an indicator signals a user as to the status/condition of the system component.

Status/condition indicating arrangement for use in electro-optical

A data processing system includes a scanning head for electro-optically reading bar code symbols and decoding such symbols into digital decoded signals; a host device having a predetermined data exchange format for exchanging data and control signals with peripheral equipment; an interface arrangement for interconnecting the host device and the scanning head, including a first connector for direct connection to the host device, a second connector for direct connection to a head cable connected to the scanning head; and a conversion circuit for converting the digital decoded signals from the scanning head into digital data signals having a format compatible with the predetermined data exchange format of the host device.

Laser scanner system for controlling the optical scanning of bar codes

An optical scanning system for reading indicia of differing light reflectivity has an optical scan module including a light emitter for emitting light onto the indicia and a light detector for detecting the reflection of light from the indicia. The scan module is adapted to be mounted on at least one finger of a user. A first peripheral module has a receiver for receiving a first signal corresponding to the detected reflection of light from the optical scan module. The first peripheral module is adapted to be mounted on an arm or wrist of the user. A second peripheral module includes a receiver for receiving a second signal corresponding to the first signal from the first peripheral module by radio frequency transmission. According to other aspects of the invention, the light detector is located in a housing separate and apart from the optical scan module.
