Abstract: A method for removing credentials from a smart grid device includes: receiving, by a receiving device, a removal request, wherein the removal request includes a device identifier associated with a smart grid device and is signed by an entity associated with a set of security credentials stored in a memory of the smart grid device, the set of security credentials restricting access to one or more components or operations of the smart grid device; extracting, by a processing device, the device identifier included in the received removal request; generating, by the processing device, a permit configured to remove the set of credentials from the smart grid device, wherein the generated permit includes the extracted device identifier; and transmitting, by a transmitting device, the generated permit to the smart grid device for removal of the set of credentials from the memory of the smart grid device.

Abstract: A node within a wireless mesh network is configured to forward a high-priority message to adjacent nodes in the wireless mesh network by either (i) transmitting the message during successive timeslots to the largest subset of nodes capable of receiving transmissions during each timeslot, or (ii) transmitting the message on each different channel during the timeslot when the largest subset of nodes are capable of receiving transmissions on each of those channels.

Abstract: Devices and methods for securely upgrading devices, such as field upgradeable units, are disclosed. In response to receiving an update object, a device may determine whether a predefined location of memory includes a predetermined value. Based on the value in the predefined location, the device may store the received update object in a verification portion of the memory. After verifying the authenticity of the update object, the device may copy the update object from the verification portion of the memory to an inactive portion. The inactive portion of the memory can be swapped with an active portion of the memory, such that the inactive portion becomes active.

Abstract: A mobile device communicates with an authenticator affiliated with a recharging facility, to identify itself. To confirm that the mobile device is connected to the correct facility, the authenticator instructs the mobile device to draw electrical charge according to an identifiable pattern. Upon detecting a charge being drawn according to that pattern, the authenticator has confirmation that the identified device is connected to the facility, and permits the charging to proceed. The amount of electricity drawn during the charging procedure can be metered, and then billed to a party associated with the identified mobile device.

Abstract: A permitting system for controlling devices in a system includes a permit issuing agent that receives a command to be sent to a device. Based upon at least one attribute of the command, the permit issuing agent identifies one or more business logic modules that is pertinent to the command. Each business logic module has a respectively different set of business rules associated with it. Each identified business logic module determines whether the command complies with the business rules associated with that module. If the command is determined to comply with the business rules of all of the identified business logic modules, the agent issues a permit for the command, and the permit is sent to the device for execution of the command.

Abstract: A plurality of nodes in a first network mitigate data restrictions on access points which are an interface between the first network and a second network. The access points advertise their access parameters to the second network to the nodes. The nodes maintain a list of the advertised access parameters of each access point. The nodes determine whether to transmit data to the second network according to a first transmission mode or a second transmission mode based on the data to be transmitted and the list of access parameters maintained by that node. In the first transmission mode, the node determines to transmit the data to a first access point having a lowest cost with that node. In the second transmission mode, the node determines to transmit the data to a second access point having fewer access restrictions to the second network than the first access point.

Abstract: In an embodiment, triplets of network-enabled FCIs operate to monitor the three phases of a power distribution system. In being network-enabled, the FCIs also operate as nodes of an RF mesh network. In an embodiment, upon the detection of a power failure, the triplet of network FCIs is serially operated so as to extend their networking capabilities by approximately three times.

Abstract: Rather than using a large number of transceivers (transmitter/receiver pairs) operating in parallel, Access Points with multiple channels are used to aggregate, or stack, transmitted response communications, e.g., transmitting multiple acknowledgements (ACKs) in a single packet to one or more sources of received packets. The method includes sending on a plurality of channels, by each of a plurality of respective first nodes, a communication to a second node, receiving on the plurality of channels, by the second node, the communication from each of the plurality of first nodes and sending, by the second node, a transmission that contains a response to each communication that was successfully received from each of the plurality of first nodes. The response to each of the plurality of first nodes is part of a single message sent by the second node.

Abstract: Systems and methods for detecting device failures in a network having nodes coupled to a central controller, in which a first of the nodes communicates with the central controller via a second of the nodes. When the second node determines that the first node has not transmitted a predetermined number of messages over a predefined number of time periods, the second node provides a failure alert to the central controller. The central controller records a failure alert received from the second node in a log. Based on a set of failure alerts received from a number of nodes recorded in the log, the central controller determines whether the first node has failed.
