Abstract: A method and apparatus for real-time in-line encryption of data transmitted over a serial channel from a source device to a target device. An encryption unit includes logic configured to receive data packets including headers with control information and data on the channel, which may be a fiber channel bus, serial ATA, serial SCSI, USB or the like. The encryption unit encrypts the data and passes the control information to the target device along with the encrypted data. The encryption unit may filter, convert or reject predetermined commands or types of information in the header to prevent covert channel transmissions. There may be one or multiple source devices, e.g. host computers, and one or multiple target devices, e.g. storage systems, configured in a variety of network topologies. The encryption unit also decrypts data and remaps control information transmitted from the target device(s) to the source device(s).

Abstract: Software code may include code to receive a first request associated with a discrete problem that is broadcast over a network of cobots. The request may be accepted based on the discrete problem to be solved. The code may also include code to determine whether a utility function associated with the plan to solve the discrete problem meets a threshold. The plan may include a plurality of steps. A report including information related to the chosen plan may be sent to the requesting cobot. Information related to the plan may include information such as the forecasted outcome of the plan. The cobot may then receive permission to implement the chosen plan. The plan may be implemented before any subplans are known or are determined to be possible. In the event that a subplan is required to carry out the plan, then a second request may be broadcast to a plurality of other cobots in the network.

Abstract: A telemetry system is described in which a plurality of channels are coupled to a bus. A control subsystem controls the channels so that one of the channels presents to the bus during its designated time period a channel characteristic. The control subsystem interrogates in the analog domain each of the channels during its designated time period, and forms a signal representative of the channel characteristic. The control subsystem may combine one or more of the signals into a digital packet, and transmit the same via transceiver over a wireless network. The channels may be contained within a submersible enclosure and displaced at intervals along the bus, thereby forming an array for monitoring waterborne threats. The array may lie along an ocean floor, may be towed by a marine vehicle, or may suspended from a deployable buoy containing the control subsystem, transceiver, and a remote power source. The array may further comprise a defensive countermeasure deployable responsive to detecting a threat.

Abstract: A system and method for imaging one or more objects in the presence of unknown phase and amplitude aberrations is described. Multiple images are collected so as to have measurement diversity and processed using a model-based approach to estimate the aberrations. An incoherent imaging model may be constructed to estimate the dependence of the imagery upon the object and the optical system, including the aberrations. A probability density function may then be calculated using the estimated model. Next, a maximum-likelihood estimate may be calculated and optimized, thus yielding a close approximation of the phase and amplitude aberrations. The estimates may then be used to estimate an image of the object or correct the system for future imaging.
