20120072568 | SWITCH MANAGEMENT SYSTEM AND METHOD - Methods and systems for managing a service provider switch are provided. According to one embodiment, a network operating system (NOS) is provided on each processor element (PE) of the switch. The NOS includes an object manager (OM) responsible for managing global software object groups, managing software object configurations, managing local software objects and groups and routing control information between address spaces based on locations of software objects. The OM performs management plane communications among software objects by way of system calls. The OM performs data plane communications among software objects by way of object-to-object channels. The switch is provisioned with a network-based managed IP service for a particular customer of the service provider by pushing the service onto an object-to-object channel that has been established between a first software object and a second software object of the software objects. | 03-22-2012 |

20120203918 | LOW POWER WIRELESS NETWORK FOR TRANSPORTATION AND LOGISTICS - Embodiments of methods and devices are disclosed for enabling network devices to join a network. These embodiments generally include a first network device, which is joined to the network, sending authentication information. If the authentication information is determined as valid by a second network device, the second network device sends a join request toward the first network device. During or after the joining process, the first and second network devices can share scheduling information. These embodiments enable a network to have additional security while consuming low amounts of power. | 08-09-2012 |
20120275360 | LOW POWER WIRELESS NETWORK FOR LOGISTICS AND TRANSPORTATION APPLICATIONS - Techniques are disclosed for reducing power of network devices in a low-power wireless network. Embodiments generally include, for a network device that periodically toggles between high-power and low-power modes, increasing the relative amount of time the network device operates in a low-power mode under certain conditions that may otherwise cause the network device to consume more power. Such conditions include when the network device fails to join the low-power wireless network and/or when the network device fails to communicate with the low-power wireless network with an accuracy above a certain threshold level. | 11-01-2012 |
20120275361 | ACCELERATED REJOINING IN LOW POWER WIRELESS NETWORKING FOR LOGISTICS AND TRANSPORTATION APPLICATIONS - Techniques are disclosed for enabling accelerated rejoining of network devices in a low-power wireless network after a connection to the low-power wireless network is lost. Embodiments generally include, for a network device that periodically conducts scans for beacons on the low-power wireless network, increasing the frequency, or scanning rate, at which the scans are performed. After a certain period of time, if the network device has not joined the low-power wireless network, the network device can implement a different scanning rate until it rejoins with the network. Additional techniques may be used to reduce power usage and preserve the structure of a portion of the low-power wireless network that has become disconnected with the rest of the network. | 11-01-2012 |
20130072223 | LOCATION-BASED DECISION MAKING FOR ASSET TRACKING DEVICES - A method of creating geographic zones may include receiving a selection of a first geographic zone located at least partially within a geographic region, storing a tree data structure that represents the first geographic zone, and sending the tree data structure to be stored on one or more asset tracking devices. The tree data structure may include a plurality of nodes organized into parent-child relationships where each of the nodes represents geographic areas. A root node may represent the geographic region, each child node may represent a sub-area of a geographic area represented by the respective parent node, each node may represent a geographic area that at least partially overlaps with the first geographic zone, and each node representing a geographic area that is entirely within the first geographic zone may include an identifier associated with the first geographic zone. | 03-21-2013 |
20130074145 | SECURE KEY SELF-GENERATION - Techniques are disclosed for providing secure critical security parameter (CSP) generation in an integrated circuit (IC). Embodiments generally include determining that an ability to read the CSP externally (e.g., through a debug interface) has been disabled before the CSP is generated. Depending on the functionality of the device, embodiments can include other steps, such as determining whether software for executing a method for providing a secure CSP is being run for a first time. Among other things, the techniques provided herein for providing secure CSP generation can increase the security of the CSP and reduce manufacturing costs of the IC. | 03-21-2013 |

20140022969 | APPLICATION AND METHOD OF INTER-FRAME GAP REDUCTION IN LOW-POWER TIME-SYNCHRONIZED NETWORKS - Techniques are disclosed for reducing the amount of overhead transmitted in ad-hoc low-power wireless networks. Embodiments generally include aggregating a plurality of data packets and prepending and appending each with associated data. The plurality of data packets then can be inserted into a single data frame, or packet for transmission. Gaps may be inserted between the data packets for timing synchronization and/or other purposes. | 01-23-2014 |
