  • Publication number: 20200143216
    Abstract: A Usage, Condition and Location System (UCLS) tag is provided, which is an active RFID tag that, in addition to location, is configured to determine the usage state and operating condition of a device. The UCLS tag includes sensors that measure physical activity of the associated equipment (vibration, magnetic activity, temperature, etc.). Algorithms may use the information obtained from the UCLS tags to map the measured sensor data to a contextual usage state and operating condition of the device.

  • Patent number: 10240861
    Abstract: A monitoring system for a cold storage device such as a vapor compression refrigerator or freezer. The monitoring system learns operating characteristics of the cold storage device and issues alarm notifications when abnormal behavior is detected. Such a system can be used as an “early warning system” to flag when a cold storage device is not operating properly. Such a system could be particularly valuable in applications that make mission-critical use of cold storage devices, e.g., biomedical or pharmaceutical research labs, blood or tissue banks, grocery stores, restaurants, and the like.

  • Patent number: 9585124
    Abstract: Presented herein are techniques for using uplink transmissions from devices (e.g., wireless tags, clients, etc.) to determine a path loss between neighboring access points. In one example, a wireless controller obtains receive signal strength information of uplink transmissions received at neighboring access points in a wireless network. The wireless controller determines an effective path loss between the neighboring access points based on the receive signal strength information for the uplink transmissions received at the neighboring access points. The wireless controller also performs radio resource management operations in the wireless network using the effective path loss determined based on the uplink transmissions received at the neighboring access points.

  • Patent number: 9357519
    Abstract: A first wireless device (e.g., an access point) receives a message from a second wireless device (e.g., a client device). The first device determines an angle-of-arrival of the message at a plurality of antennas of the first wireless device. The first device compares the angle-of-arrival with an angle-of-arrival threshold to determine whether to transmit a response message to the second wireless device. In one example, the first wireless device is a wireless access point device operating in a wireless network, the second wireless device is a wireless client device operating in the wireless network, the message is a probe request message and the response message is a probe response message.

  • Publication number: 20150358892
    Abstract: A wireless access point uses broadcast Service Set Identifiers (SSIDs) to advertise services available to a user device within range of the access point. The access point receives information about a first service available from a first service provider, and generates a first SSID associated with the first service. The access point receives information about a second service available from a second service provider, and generates a second SSID associated with the second service. The access point broadcasts the first SSID during a first period of time in a wireless network, and broadcasts the second SSID in the wireless network during a second period of time that is non-overlapping with the first period of time.

  • Patent number: 8718560
    Abstract: At a wireless device operating in an unlicensed frequency band, energy received at a plurality of antennas is analyzed to detect interference on a channel in the unlicensed frequency band. The type of interference detected in the received energy is determined. Parameters are then generated for a nulling filter based on the type of interference detected in the received energy. The nulling filter is applied to the received energy at the plurality of antennas to produce a spatially filtered output. The spatially filtered output is evaluated to determine whether to send a transmission on the channel in the unlicensed frequency band.

  • Patent number: 8676144
    Abstract: Interference in an unlicensed frequency band is spatially filtered out from received signals at a wireless device operating in the unlicensed frequency band. Energy received at a plurality of antennas of the wireless is device is analyzed to detect interference in the unlicensed frequency band. The detected interference is classified by type. Parameters for a nulling filter are generated or selected based on the type of interference detected in the received energy. During a time interval when it is expected to receive desired signals, the nulling filter is applied using the parameters to signals obtained from energy received at the plurality of antennas during the time interval.

  • Patent number: 8411629
    Abstract: Techniques are provided herein for computing a video admission control metric used to determine whether to admit a new video stream to a wireless network. The video admission control metric is computed using several measurable parameters of the wireless network. The dynamic nature of this process takes into account many real-time factors that affect admission control, such as traffic load, channel conditions, and overlapping basic service set (BSS) interference.

  • Patent number: 8374113
    Abstract: Techniques are provided to reduce or restrict the bandwidth consumed by multicast video streams on wireless links, such as wireless IEEE 802.11 links. At a central multicast video transcoder apparatus configured to communicate with one or more access point devices operating in a wireless local area network, one or more multicast video streams are re-encoded the one or more multicast video streams to produce a corresponding one or more wireless-friendly multicast video streams that have a reduced bandwidth from a bandwidth of the received multicast video streams. The one or more wireless-friendly multicast video streams are thus adapted for wireless transmission by access point devices to wireless client devices in the wireless local area network. The one or more access point devices receive the one or more wireless-friendly multicast video streams and process the one or more wireless-friendly multicast video streams depending on conditions in a radio channel used by the access point device.

  • Patent number: 8369305
    Abstract: At a plurality of first devices, wireless transmissions are received at different locations in a region where multiple target devices may be emitting. Identifier data associated with reception of emissions from target devices at multiple first devices is generated. Similar identifier data associated with received emissions at multiple first devices are grouped together into a cluster record that potentially represents the same target device detected by multiple first devices. Data is stored that represents a plurality of cluster records from identifier data associated with received emissions made over time by multiple first devices. The cluster records are analyzed over time to correlate detections of target devices across multiple first devices.

  • Patent number: 8331312
    Abstract: Techniques are provided to reduce contention (interference) between bursts associated with multiple isochronous traffic flows. Generally, the techniques involve, at a plurality of wireless access point devices and/or a plurality of wireless client devices in a wireless network, initiating bursts of wireless transmissions carrying isochronous traffic from wireless access point devices to their associated client devices and/or from wireless client devices to their respective wireless access point devices at start times that are scheduled so as to reduce a likelihood of interference between multiple bursts of wireless transmissions for different isochronous traffic flows.
