  • Publication number: 20180042077
    Abstract: Systems, methods, and apparatuses are described that manage lighting configurations which provide the ability to finely control LED light output, such as modifying brightness and/or change light frequencies and/or mix light colors, embed data channels etc. to achieve numerous functional improvements including simultaneous data transmission. Managing lighting control configurations will enable a growing number of useful functions that can adjust lighting optimally for current conditions, such as cutting through fog, setting a mood or improving aesthetics and even provide vitamin D light therapy without circadian disruption. In addition, lighting configurations can be employed to tell LED lights how to behave during installation and when detecting problems. This allows for simpler installation and management of lighting.

  • Publication number: 20180040225
    Abstract: The combination of LED lighting and particulate detectors are enhanced by exploiting the light degradation/reflection/wavelengths detected, absorbed or frequency shift seen in lighting due to the presence of smoke, gas or other molecules (such as explosives) in the air can be detected. The use of LEDs is expanded well beyond simple lighting and energy savings to include not only smoke and fire detection by also to scan for gases and particulates found based in the usage environment.

  • Patent number: 8848669
    Abstract: A system and method wherein mobile nodes scan both 802.16 and 802.11 radio channels for neighbor access points. A mobile node reports both WiMax and WiFi neighbor access points to its parent access point. A parent access point advertises both WiMax and WiFi neighbor access points to child mobile nodes to facilitate faster roaming and load balancing. A parent WiMax AP can direct a mobile node to roam to a neighbor WiFi access point that has a lighter load or offers enhanced services. As an option, a location tracking protocol is used to determine the location of a mobile node and the mobile node's parent AP advertises neighbor APs that offer services in the mobile node's location.

  • Patent number: 7920519
    Abstract: Facilitating node mobility includes facilitating a communication session for a mobile node communicated along a first communication path. A first anchor point manages context information for the communication session, where the context information comprises information for supporting the communication session. A command to transfer the context information to a second anchor point is received from a home agent. The second anchor point is operable to facilitate communication of the communication session along a second communication path. The context information is transferred in response to the command.

  • Patent number: 7792993
    Abstract: An address assignment mechanism allows an address server to receive requests for network addresses from computer systems. Based on an identity of the requesting computer system, the address server selects an address for use from local addresses or guest addresses. If the address server identifies the requesting computer system as a guest computer system, then a guest address selected from a set of guest addresses is assigned and provided to that computer system, whereas if the address server identifies the requesting computer system a local computer system then the address server selects and assigns a local address (from the set of local addresses) to the requesting local computer system. Data communications devices selectively route data portions sent from computer systems depending upon if those data portions contain guest addresses or not. Selective transport therefore restricts access to certain parts of the network if the data portion contains a guest address.

  • Patent number: 7657268
    Abstract: Facilitating mobile node mobility includes facilitating at a current access location a communication session for a mobile node. Context information for the communication session is managed, where the context information comprises information for supporting the communication session. A predictive set comprising one or more predicted next access locations is established for the communication session. The context information is transferred to the predicted next access locations prior to the communication session moving to an actual next access location.

  • Patent number: 7564872
    Abstract: A system and method are provided which enable a data communications device to be programmed to automatically and dynamically modify allocation of resources upon the occurrence of specific events or times without having to break active sessions of data communications. Resource allocations can be made by bandwidth reservations provided to a data communications device via a network policy or via individual bandwidth reservation messages. The bandwidth allocation information can specify a session of data communication and future bandwidth modification information, such as a time or event, that will cause the data communications device to modify an amount of bandwidth reserved for the specified session of data communications.

  • Patent number: 7536187
    Abstract: Supporting communication sessions at a mobile node includes determining at a mobile node an address for one or more interior network elements of a network system. A interior network element is distinct from an edge network element of the network system, and is operable to establish a communication session. An address for an interior network element is inserted into packets. The packets are sent from the mobile node to the interior network element to communicate directly with the interior network element. The communication session is established using the interior network element.
