Publication number: 20220369068Abstract: A wireless room occupancy monitor, system and training method are provided. The room occupancy monitor includes an antenna array configured to detect wireless transmissions from a tag device; a wireless transceiver configured to receive the wireless transmissions detected by the antenna array and produce receive signals; a processor configured to process the receive signals; and a motion sensor coupled to the processor and configured to wake up the processor in response to detecting when the tag device enters or exits a room. The monitor is configured to be mounted proximate an entryway to the room. After the motion sensor wakes up the processor, the processor is configured to power on the wireless transceiver and run an algorithm on a sequence of received signal strength estimates and array response vectors derived from the receive signals to determine when the tag device has entered or exited the room via the entryway.Type: ApplicationFiled: April 27, 2022Publication date: November 17, 2022Inventors: Gary L.

Patent number: 10240861Abstract: 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.Type: GrantFiled: August 3, 2018Date of Patent: March 26, 2019Assignee: Emanate Wireless, Inc.Inventors: Gary L.

Patent number: 9585124Abstract: 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.Type: GrantFiled: November 25, 2013Date of Patent: February 28, 2017Assignee: Cisco Technology, Inc.Inventors: Neil R.

Patent number: 9357519Abstract: 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.Type: GrantFiled: March 10, 2014Date of Patent: May 31, 2016Assignee: Cisco Technology, Inc.Inventors: Neil R.

Publication number: 20150358892Abstract: 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.Type: ApplicationFiled: June 5, 2014Publication date: December 10, 2015Inventors: Santosh Pandey, Jagdish Girimaji, Neil R.

Patent number: 8718560Abstract: 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.Type: GrantFiled: July 7, 2011Date of Patent: May 6, 2014Assignee: Cisco Technology, Inc.Inventors: Hang Jin, Li Guo, Paul J.

Patent number: 8676144Abstract: 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.Type: GrantFiled: April 14, 2011Date of Patent: March 18, 2014Assignee: Cisco Technology, Inc.Inventors: Li Guo, Hang Jin, Paul J.

Patent number: 8411629Abstract: 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.Type: GrantFiled: February 12, 2010Date of Patent: April 2, 2013Assignee: Cisco Technology, Inc.Inventors: Lu Qian, Sandeep J.
