  • Patent number: 8674806
    Abstract: A system can be for use with a number of reference tags disposed at respective reference locations in a coverage area. The reference tags can be configured to form a wireless mesh network. A system can include a first tag configured to communicate with the reference tags. The first tag can operate in a sleep mode and includes a motion sensor. The first tag is woken out of the sleep mode on a first periodic basis to communicate with the reference tags. The first tag is woken out of the sleep mode at a second periodic basis in response to motion signal from the motion sensor. The second periodic basis is more frequent than the first periodic basis. The system can also include a positioning system configured to receive data related to the communication between the first tag and the reference tags. The positioning system can be configured to process the data to determine a location of the first tag.

  • Patent number: 8400268
    Abstract: The system comprises a plurality of reference tags affixed to reference locations in a coverage area and configured to form a wireless mesh network. The system also includes a call tag configured to communicate with the plurality of reference tags and to collect data regarding the communication with the plurality of reference tags. The call tag is configured to send a first signal in response to an event. A positioning system is coupled to the wireless mesh network and configured to receive the first signal and the data collected by the call tag. The positioning system is further configured to process the data collected by the call tag to determine the call tag location with respect to the plurality of reference tags. A portable electronic device is configured to communicate with the wireless mesh network and configured to receive call tag location from the positioning system.

  • Patent number: 8026814
    Abstract: An asset tracking system includes a station, transmitting points, and an asset tag. The asset tag can be used for communicating with the transmitting points to form a mesh network. The station receives data associated with signal strengths between transmitting points and asset tag. The station analyzes the data associated with a number of the transmitting points and determines the location of the asset tag.

  • Patent number: 7885687
    Abstract: In one aspect, a digital device comprises a wireless station, a universal serial bus (USB) port, a memory, and a processor. The processor is configured to detect a coupling of a flash device to the USB port and obtain wireless network configuration information from the flash device. The wireless network configuration information comprises a network name and a security key for a wireless communications network. The processor is further configured to store the wireless network configuration information in the memory, configure the wireless station using the wireless network configuration information, and connect the wireless station to the wireless communications network based on the wireless network configuration information.

  • Patent number: 7787014
    Abstract: In some implementations, a portable imaging system includes a host computer, a docking station connected to the host computer, and a portable imaging device intermittently attached to the docking station and configured to communicate data with the host computer through a wired connection when the portable imaging device is attached to the docking station, and through a wireless connection when detached from the docking station. In some implementations, a method for communicating data between a portable imaging device and a computer is also provided. In some implementations, the method includes determining whether a wired connection is established between the portable imaging device and the computer. In some implementations, if established, the wired connection is used to communicate data between the portable imaging device and the computer.

  • Patent number: 7567651
    Abstract: Systems and techniques are provided for a directional antenna system that employs a wireless link between x-ray apparatus. The system includes a host computer, an x-ray tube with an emission scan channel, a first directional antenna connected to the x-ray tube and with an orientation parallel to the emission channel, a second antenna wirelessly communicating with the first directional antenna, an x-ray detector wirelessly communicating with the x-ray tube, and a rigid panel supporting the second antenna and the x-ray detector being in contact with the emission scan channel. Specific techniques are employed to manage antenna direction and transmission.

  • Patent number: 7321784
    Abstract: A method for providing configuration information for use in installing a new wireless station to a wireless network that minimizes errors is presented. The configuration information is distributed by storing the configuration information onto a device with a memory and then distributing the device to the users interested in installing new wireless stations. The device is attached to a computer to which the wireless station is coupled, initiating a transfer of the configuration information. The computer uses the configuration information to configure the wireless station. The method also provides a way to limit access to the configuration information through the use of encryption and limiting the number of times the configuration information is retrieved. The method is also an effective way to distribute security keys for encryption systems whose purpose is to secure communications in a wireless network.

  • Publication number: 20040102192
    Abstract: A wireless LAN monitoring application runs on a computing device and scans through all possible wireless channels. The application then displays information indicative of the communication activity level on each channel and permits a user to select a channel having an access point with which to associate. The selection may be based on a desired network the user wishes to access, a channel that has the highest signal-to-ratio, signal quality, or channel utilization or, when looking for a channel to set up an ad hoc network, a channel that has a low signal-to-noise ratio, signal quality, or channel utilization.

  • Publication number: 20040076138
    Abstract: A test system is disclosed in which the packet error rate of a wireless card can be determined without having knowledge of the software interface to the card. The wireless card under test is placed inside an anechoic chamber. Test equipment emulates an access point and the card under test “associates” itself with the emulated access point. The test equipment includes an arbitrary waveform generator, RF signal generator, and a controller which emulates an access point. The controller commands the arbitrary waveform generator and RF signal generator to transmit a test data packet to the card under test. If the test data packet is correctly received by the test card, the card transmits back an acknowledgment packet. The controller computes the packet error rate based on the number of lost packets relative to the total number of test data packets sent.
