摘要： System and method for scheduling and coordinating transmission signals in a wireless data communications network, comprising a master node and at least one tag node. In some embodiments, the network may also include a slave node. The master node divides time into repeating time division blocks comprising a configuration window and at least one transaction window. During the configuration window, the master node provides operating parameters to the tag or slave nodes, including a time slot within the transaction window that is reserved for the tag or slave nodes to broadcast data to the master node. The transaction window is subdivided into multiple reserved time slots, and each slot is assigned to a specific tag or slave node. When a reserved time slot arrives, the tag or slave node will broadcast data signals to the master node. The master periodically adjusts the transmission schedule for each tag or slave node, as needed, to ensure that every tag or slave node continues to broadcast only during its reserved time slot, thereby reducing communication data collisions and optimizing the overall performance and throughput of the data communications network.

摘要： A device, mobile system, and method for scanning a source of information are described. During scan operations, the scanning device is energized by an on-board supercapacitor power source and is worn upon an extremity of a user. The scanning device is operable for scanning the information source, accessing the information from the source based on the scanning, and generating a signal comprising data related to the accessed information. The generated scan data signal is transmitted for processing to a base station, which is worn remotely from the scanning device, for example on the user's belt.

摘要： An alarm tag comprising a first input unit for generating signals for setting (to ON) or resetting (to OFF) an alarm system of the alarm tag. The alarm tag further includes a second input unit for generating signals for arming the alarm tag and triggering an alarm, and an independent auxiliary input unit that generates independent signals that arm the alarm tag and trigger an alarm. When both the second and the auxiliary input units generate a first signal, the alarm system of the alarm tag is armed and set to ON, and when any of the second and third auxiliary input units generate a second signal while the alarm tag is armed and ON, the alarm system of the alarm tag triggers an alarm, thereby preventing tampering and bypassing of one of the second and auxiliary input units to disarm the alarm.

摘要： Systems and methods for use in detecting the presence of an RFID device are provided. One RFID detection system includes a detection circuit that includes an oscillating circuit. The detection circuit is configured to hold the RFID detection system in a low power mode in which the RFID detection system is configured to not actively attempt to communicate with nearby RFID devices. The detection circuit is further configured to monitor one or more parameters of a signal of the oscillating circuit and compare the one or more monitored parameters to one or more reference parameters. The detection circuit is further configured to, based on the comparison, determine whether to transition the RFID detection system from the low power mode into an active communication mode in which the RFID detection system is configured to actively attempt to communicate with nearby RFID devices.

摘要： A method of decoding an encoded signal includes steps of receiving the encoded signal, creating a decoding signal by delaying the encoded signal by a predetermined amount of time Δ, sampling the encoded signal using the decoding signal, and determining a value of each of a plurality of decoded bits represented by the encoded signal based on the sampling. Also, a method of operating a shift register wherein the shift register has an initialization state wherein a first binary symbol is stored in a first position and a second binary symbol different than the first binary symbol is stored in each of one or more intermediate positions and a last position. The method includes determining that the shift register is full responsive to detecting that the first binary symbol has been stored in either one of the intermediate positions or the last position.

摘要： An inventory monitoring controller maintains information reflecting a current inventory of articles based on radio frequency identification (RFID) tag identifying information received from one or more RFID tag readers in the context of inventory polling operations. In an embodiment, the controller also adjusts an operational parameter (e.g., a missing article detection threshold or a variable polling parameter) based on an analysis of the RFID tag identifying information. For example, a variable polling parameter may be adjusted in response to an occurrence of a triggering event (e.g., an inventory change indicated by the RFID tag identifying information or an occurrence of a temporal event), and a missing article detection threshold may be adjusted based on historical information relating to the detection of (or failure to detect) a particular RFID tag.

摘要： Methods for determining a range rate of a backscatter transponder and readers implementing the methods are described. The reader transmits a continuous wave signal and receives a modulated reflected response signal from the transponder, mixes the modulated reflected response signal with the carrier frequency to produce a downconverted signal, bandpass filters the downconverted signal to pass a bandpass filtered signal containing at least the modulation frequency, applies a non-linear amplitude transfer function to produce a modulation-suppressed signal, and measures the frequency of the modulation-suppressed signal and determines the range rate from the measured frequency.
