Patent number: 8879574Abstract: One embodiment of the present invention provides a system for configuring an access point in a wireless network. During operation, the access point discovers one or more existing access points associated with the wireless network. The access point then obtains a set of configuration information from one existing access point, and synchronizes a local timestamp counter to a selected existing access point, thereby allowing the access point to be configured without using a centralized management station.Type: GrantFiled: December 9, 2013Date of Patent: November 4, 2014Assignee: Ubiquiti Networks, Inc.Inventors: Sriram Dayanandan, Bo-chieh Yang, Yuan-Hsiang Lee, Keh-Ming Luoh, Robert J.

Patent number: 8880204Abstract: An interfacing device is configured to process one or more rules, based on sensor data, to perform a predetermined action. During operation, the device can receive a device configuration that includes a rule for the interfacing device. The rule can include an action description for performing an action, and can include a condition that takes sensor data as input and indicates criteria for performing the action. The device can store the rule in a rule repository, and determines a remote interfacing device that generates data associated with the rule's condition. The device can also subscribe to the data from the remote interfacing device.Type: GrantFiled: January 8, 2013Date of Patent: November 4, 2014Assignee: Ubiquiti Networks, Inc.Inventors: Randall W.

Publication number: 20140005810Abstract: A sensor-monitoring interfacing device is coupled to one or more physical devices that include sensors for measuring physical attributes. During operation, the interfacing device obtains and processes sensor data from the physical devices. When the interfacing device obtains sensor data from a physical device, the interfacing device selects a rule to process based on the obtained sensor data. If the interfacing device determines that the rule's condition is satisfied, the interfacing device can process the rule's action description to perform a corresponding action.Type: ApplicationFiled: January 8, 2013Publication date: January 2, 2014Applicant: Ubiquiti Networks, Inc.Inventors: Randall W.

Publication number: 20140006506Abstract: A load-monitoring interfacing device obtains and processes sensor data from an electrical load. The interfacing device can include at least one power outlet to provide power to a corresponding electrical load. During operation, the interfacing device can obtain sensor data from a local power outlet coupled to an electrical load, such that the sensor data can indicate an electrical measurement associated with the electrical load. The interfacing device selects a rule to process based on the obtained sensor data, and processes the rule to determine whether to perform an action. If the rule's condition is satisfied, the interfacing device proceeds to processing the rule's action description to perform the action, such as to enable or disable a power outlet, or to perform any other pre-defined action.Type: ApplicationFiled: January 8, 2013Publication date: January 2, 2014Applicant: Ubiquiti Networks, Inc.Inventors: Randall W.

Publication number: 20140006605Abstract: A local controller maintains a local database which stores information associated with a set of interfacing devices of a local-area network. The local database can include a database mirror for a remote database, of a remote controller, that stores information for a set of provisioned interfacing devices. During normal operation, a remote controller hosting the remote database can have primary control of interfacing devices within the local area network and/or other network domains, and the local controller maintains the local database to include at least a subset of the remote database. However, when the local controller determines that the remote controller has gone offline, the local controller can obtain primary control of interfacing devices within the local area network.Type: ApplicationFiled: January 8, 2013Publication date: January 2, 2014Applicant: UBIQUITI NETWORKS, INC.Inventors: Randall W.
