摘要： A system and method described for tracking portable devices. The system may include a transmitter which transmits wireless inquiries to a plurality of portable devices and a receiver receiving replies to the inquiries from the portable devices. In addition, the system may include a memory storing identifier data corresponding to the portable devices and a processor coupled to the memory and to the receiver, the processor retrieving from each reply, identifier data uniquely identifying a particular one of the portable devices which generated the reply and comparing the identifier data to the stored identifier data. Furthermore, the system may include an alarm system coupled to the processor and controlled based on the comparison of stored identifier data to the identifier data retrieved from the replies.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An imager in an imaging reader captures light from a target, generates image data from the captured light, and generates a pixel clock signal having a pixel clock frequency in synchronism with the image data. A controller is connected via an electrical conductor to the imager, and controls the imager to transfer the image data, receives the image data, and processes the image data. A circuit suppresses electromagnetic radiation generated by the conductor during the image data transfer, and includes a spread spectrum modulator for modulating the pixel clock signal to generate a variable spread spectrum signal having a spread spectrum frequency that periodically varies above and below the pixel clock frequency, and a buffer having a plurality of registers for receiving and temporarily storing the image data, and for varying as a function of the spread spectrum frequency how much of the image data is being temporarily stored.

摘要： A system and method for processing scanner signals by storing both a standard digitizer signal and a more detailed digitizer signal for decoding. The decoder can then use the standard digitizer signal by default and in those cases when the bar code pattern cannot be decoded using the standard digitizer signal the decoder may access the more detailed digitizer signal.
