  • Publication number: 20140320629
    Abstract: Apparatus configured for operation in an underwater environment are provided. A device includes a camera and a transceiver. The camera can capture, within a predetermined interval of time, first light within a first frequency range of light and second light within a second frequency range of light. The camera can generate a first image based on the first light and a second image based on the second light. The first frequency range of light can differ from the second frequency range of light; for example, the first frequency range can include 420-450 nanometers (nm) and the second frequency range can include 830 nm. The transceiver can send the images and receive commands based on haptic feedback generated based on the first image and the second image. For example, an actuator can be configured to be controlled by one or more commands.

  • Patent number: 7602792
    Abstract: A reconfigurable architecture for wireless digital data and voice communications is provided for ad hoc and/or an ad hoc collection of organized networks. At least some user wireless communication units serve as relay stations for other users units, enabling any user within the range of another, participating user to gain access to the local- and wider-area networks in a multihop process. Reconfigurable hardware enables dynamic protocol “preferencing”, and easy upgrades to potential future wireless protocol standards. Power-efficient communication takes place by using multihop radio communication at the local level and high-speed point-to-point links (e.g. fiber, satellite) at the global level. Microcells within a network community are aggregated into cells by use of a local-area-network (LAN) backbone of higher speed wireless and/or wired connections. Every time a microcell connects to the wireless backbone, microcells or individual users in surrounding blocks can also connect to the network.

  • Publication number: 20060242130
    Abstract: An embodiment of the present invention is a technique for information retrieval. Information is searched using a set of search inputs representing a query from a user to produce a plurality of search results. The search results are analyzed using at least one of a conjunctive search, a link discovery, and a knowledge base to generate enhanced search results.
