Abstract:
A first portion of a cryptographic key can be conveyed through a secure channel to a device that can interact with a home network. After the first portion is received, a prompt can be sent by the recipient of the portion through a non-secure channel to the sender of the portion to send a second portion of the key. The cryptographic key can be constituted from the received portions and used by the device to secure communications with home network.
Abstract:
Systems and techniques are provided for a backup wide area network connection for access points and routers. A network interface may be able to connect to wide area network over a broadband connection. A cellular modem may be able to connect to the wide area network through a cellular network. The cellular modem may be distinct from the network interface. A processor may be connected to the network interface and the cellular modem and may be able to detect that the broadband connection between the network interface and the wide area network is not connected and, in response, activate the cellular modem to connect to the cellular network, receive configuration data using the cellular modem, and apply a configuration setting from the received configuration data to establish the broadband connection through the network interface.
Abstract:
The disclosed subject matter may provide a system and methods for commissioning a device or appliance into a network. A processor may detect the insertion of a removable device into a data receptacle of a first device. The first device may be an appliance or a network controller. Information may be retrieved from or delivered to the removable device. The information may be information specific to the appliance, such as model number, or may be information related to the network controller. For example, information delivered from the network controller to the removable device may include a network address assignment and network protocol to be used by an appliance when the appliance communicates with the network. The removable device may be removed from the first device and inserted into a data receptacle of a second device.
Abstract:
Collisions in wireless networks may be avoided by stacking acknowledge messages, relaying the stacked acknowledge messages, and reducing the number of acknowledge frames transmitted as a result of successful stacked acknowledge message transmissions. Additionally, a blind relay setup may be implemented to increase successful transmission rates such that a relay node in a transmission chain is configured to relay a frame without addressing the relay to a specific node. Non-neighboring nodes may receive frames out of order and relay the frames despite the out of order delivery.
Abstract:
A method for registering for an appliance event notification comprises scanning a machine-readable code by a device and sending a request to register for an event notification to an appliance. A user interface corresponding to the appliance is displayed and the user interface includes an identification of at least one appliance specific event. A selection of an appliance specific event is received and a request to register for an event notification corresponding to the selected appliance specific event is sent to the appliance. An event notification is received upon occurrence of the event at the appliance. Additionally, the user interface includes an identification of at least one appliance specific control function. A request to register for control of the appliance corresponding to a selected appliance specific control function is sent to the appliance. Accordingly, instructions for control of the appliance are sent from the mobile device.
Abstract:
A method and system are described that allow a device operating in coordination with other devices to synchronize the devices operation with the other devices. A controllable device processor may determine that a received data packet is a retransmission of an initial control command data packet. The processor may obtain from the retransmitted data packet a start value and a time indicator related to performance of the operation. A ramp rate related to the operation to be performed may be obtained. Using the time indicator, an adjusted ramp rate may be calculated. An output value for the device may be set based on the start value, the adjusted ramp rate, and the time indicator. The adjusted ramp rate may result in completing the operation at substantially the same time as though the device received the original command.

Abstract:
Disclosed is a simulcast approach to broadcasting a message from each device, or node, of a network. A source device, such as a wall switch, may broadcast a message that may be received by a plurality of devices, such as light bulbs, in a network. Each of the plurality of devices may receive the message at substantially the same time. In response to the message, the receiving devices may determine if the message is to be retransmitted. If the message is to be retransmitted, it may generate a modified message. Each of the plurality of devices may transmit the modified message substantially simultaneously. To maintain timing to the source device between the devices in the network, the message may be configured to facilitate synchronization of the clocks to a timing signal in the message.
Abstract:
Disclosed are methods in which a source device that may multicast a message to a plurality of destination devices. The source device may receive an acknowledgement from less than all of the plurality of destination devices. Each acknowledgement may include an indication of the destination device from which the acknowledgement is received. A destination device may process the multicast message and generate an acknowledgement in response. In response to a time period subsequent to transmission of the multicast message, the source device may generate an updated message that indicates an acknowledgement status of each destination device associated with the group identifier from which an acknowledgement has been received.
