Abstract: Techniques for representing a scene or map based on statistical data of captured environmental data are discussed herein. In some cases, the data (such as covariance data, mean data, or the like) may be stored as a multi-resolution voxel space that includes a plurality of semantic layers. In some instances, individual semantic layers may include multiple voxel grids having differing resolutions. Multiple multi-resolution voxel spaces may be merged or aligned to generate combined scenes based on detected voxel covariances at one or more resolutions.

Abstract: A network device for distributing authentication information between authorized nodes for purposes of concurrently “pre-authenticating” a mobile user at a plurality of points throughout a LAN is disclosed. When a client attempts to access the network through the network device, the network device attempts to authenticate the client based on the credentials presented by the user. If authenticated, the client is admitted into the network at the network device and the client's pre-authentication information transmitted to one or more network nodes associated with an authentication group. Upon receipt of the pre-authentication information, the one or more network nodes are authorized to admit the client into the network at those nodes in addition to the network device at which the client was initially authenticated, thereby concurrently pre-authorizing the client at multiple points across the network.

Abstract: A routing device comprises a port accessible by a plurality of computers, processor-executable instructions configured for acquiring a DHCP-identified network address of a computer connected to the port in response to identifying the network address during monitoring of DHCP communication, and processor-executable instructions configured for configuring the port with an address route exclusive to the DHCP-identified network address in response to acquiring the DHCP-identified network address. Configuring the port includes creating a Classless Inter Domain Routing (CIDR) network address mask corresponding to the DHCP-identified network address and assigning the CIDR network address mask to the port.

Abstract: A system and method for automatically suspending power from an IEEE 802.3af Power Sourcing Equipment (PSE) switch to one or more Powered Devices (PDs) in accordance with user defined power allocation policies is disclosed. The PSE switch includes a classifier to associate each switch port with a power allocation policy and assign the applicable power priority level. The IEEE 802.3af PSE switch also includes a power manager to selectively allocate power between the PDs in accordance with those policies during a power outage, for example. If the switch is unable to provide power to each of the PDs, power to ports associated with a relatively low power priority is suspended before suspending power to higher priority ports. The policies may be automatically distributed to and implemented by multiple devices throughout a network without an administrator manually configuring the priorities base on knowledge of the specific types of end nodes coupled to the various ports or their priorities.
