An apparatus for use in an RFID data collection system includes an antenna portion for wirelessly exchanging signals and a memory portion for storing RFID data. A signal processing portion is coupled among the antenna portion and the memory portion. The signal processing portion is configured to receive RFID data and to at least encode or decode the received RFID data via at least one spreading code, such as a mutually orthogonal code. Other configurations are also disclosed.

RFID tags with CDMA communication capabilities

A mobile computing device is disclosed for displaying backlight and diffuse reflecting information. The mobile computing device is configured to include a processor, a first LCD display unit connected to the processor, and a second diffuse reflecting display unit connected to the processor. The mobile computing device is further provided with a display panel interface, such as a mouse or a gravity detecting device like an accelerometer, configured to detect a property for activating a display type. The processor is configured to send information to be displayed to the first display unit or the second display unit or both depending on the display type property detected.

An apparatus for use in an RFID data collection system includes an antenna portion for wirelessly exchanging signals and a memory portion for storing RFID data. A signal processing portion is coupled among the antenna portion and the memory portion. The signal processing portion is configured to receive RFID data and to at least encode or decode the received RFID data via at least two orthogonal modulation signals.

RFID tags with orthogonal communication capabilities, and associated systems

An apparatus for use in an RFID data collection system includes an antenna portion for wirelessly exchanging signals and a memory portion for storing RFID data. A signal processing portion is coupled among the antenna portion and the memory portion. The signal processing portion is configured to receive RFID data and to at least encode or decode the received RFID data via space-time block codes (STBC). For example, an RFID tag employs two spatially separated antennas and circuitry for transmitting to an RFID reader data stored in tag memory as STBC encoded data. Other configurations are also disclosed.

A system and method of autofocusing an optical system uses transforms of images or portions of images formed by the optical system. A detector is used to capture images at different positions relative to the optical system. Transforms and blur spread parameters are calculated for the images for use in determining a position to which the detector should be moved to autofocus the system.

System and method for autofocusing an optical system through image spectral analysis

Data carriers (such as RFID tags) are formed into clusters of data carriers. Each cluster has at least one bridge data carrier that can communicate with a bridge data carrier of another cluster, thereby allowing data carriers in each cluster to communicate directly or indirectly with each other using a stochastic communication protocol method. Direct tag-to-tag communication capability is provided between data carriers in each cluster and/or between clusters. The data carriers can backscatter and modulate a carrier wave from a source, thereby using the backscattered and modulated carrier wave to convey data to each other.

Stochastic communication protocol method and system for radio frequency identification (RFID) tags based on coalition formation, such as for tag-to-tag communication

A system and method is described for determining a distance to a desired target via correlating a pulse modulated signal with its corresponding reflected signal, while compensating for noise error in the reflected signal to allow for a more precise distance determination. Further details and features are described herein.

System and method for range-finding

A carrier structure has a plurality of cells. A corresponding plurality of objects having data carriers, such as radio frequency identification (RFID) tags, is placed in each cell. Each cell has an indicator associated therewith and is defined by walls that substantially prevent waves (such as RF waves) from propagating between cells. A control module is coupled to the carrier structure and is operative to selectively activate individual ones of the indicators. An automatic data collection device (such as an RFID reader) interrogates the data carriers of the objects placed in the cells, and the data carriers can provide response signals to the data collection device. The control module also monitors the response signals using an antenna present in each cell. If the data collection device selects a particular one of the responsive data carriers, the data collection device provides a notification signal to the control module to notify the control module of the selection. The control module then identifies and selects the cell of an object of interest having the selected data carrier affixed thereon, and initiates activation of the indicator associated with the selected cell, thereby identifying the location of the object of interest.

A system and method is described for determining a distance to a desired target via correlating a pulse modulated signal with its corresponding reflected signal, while compensating for noise error in the reflected signal to allow for a more precise distance determination. The system and method determine a phase shift of an echoed signal in response to a transmitted signal incident onto an object to thereby determine a distance, wherein the system analyzes an overlap region between a second signal that is a reflection of a first signal incident on the object. The first signal is modulated by one or more pulses having a defined modulation frequency. Further details and features are described herein.

System and method for laser range-finding

A data request from a requesting device is received at a network of wireless sensor nodes. The data request is then forwarded through the network of wireless sensor nodes to a source wireless sensor node, where data responsive to the data request is generated. A reply including the responsive data is then forwarded along at least two communication paths through the network of wireless sensor nodes back to the requesting device.

Systems, methods and devices for collecting data from wireless sensor nodes

A wireless sensor network includes a network sink node and a plurality of cluster nodes. The cluster nodes are configured to pass communications upstream and downstream. Each cluster node has a communication range, or coverage area. A cluster node is configured to communicate with sensor nodes within the coverage area of cluster node. The sensor nodes are configured to register with at least one cluster node. The cluster nodes are configured to register with the network sink. Identifiers for the sensor nodes may be dynamically generated. Identifiers for the cluster nodes may be dynamically generated.

A lab-on-chip system comprises an antenna and a communications subsystem to wirelessly transmit information from the lab-on-chip system. The communications subsystem may also receive information, data or instructions from an off-chip system or device. The lab-on-chip system may comprise a passive power subsystem coupled to an antenna to wirelessly receive power in the form of an electromagnetic field, which provides electrical power derived therefrom to at least one other subsystem of the lab-on-chip system.
