  • Patent number: 8301075
    Abstract: A tactical radio includes a radio frequency (RF) processing module having a receiving component path and a transmitting component path. A signal processing module coupled to the RF processing module includes a jammer detection stage for identifying a type of jamming signal on a channel over which communications signals are received simultaneously. A jammer model stage in the signal processing module produces a waveform model for the jamming signal, and a channel model stage replicates propagation conditions on the channel and produces a corresponding cancellation signal. The cancellation signal is coupled at such a level into the receiving component path so as to cancel the jamming signal from received communications signals at the front end of the radio. Any residual jamming signals may then be removed by a secondary jamming cancellation stage operating at baseband.

  • Patent number: 8284738
    Abstract: Communications in a mobile network are scheduled by defining reservation frames having time slots during which network nodes can transmit certain traffic loads while avoiding interference. The nodes maintain maps that identify the slots as either free or reserved based on each node's existing reservations, and reservation information the node receives from neighboring nodes. A node wishing to transmit traffic determines the number of slots required to carry the traffic, selects a first set of slots from among those identified in its maps as free, and transmits a reservation initiation message (RIM) that identifies the first set of slots. Nodes receiving the RIM determine which, if any, of the first set of slots are already reserved based on their own maps, and transmit counter reservation initiation messages (CRIMs) if any slots are reserved. The CRIMs also identify those slots that the CRIM transmitting nodes determine to be currently free.

  • Patent number: 8209066
    Abstract: Outside air enters a ram air scoop on an aircraft frame, and is ducted to a ram air control valve. The air control valve outputs a desired air mass flow to a cyclone air-water separator which removes moisture and produces a dry air flow. A heater assembly heats the dry air to a desired temperature and directs the heated air into an equipment bay enclosure on the aircraft. The relative humidity of the heated air is sensed by an air moisture sensor which produces a corresponding signal. Other sensors disposed near a payload in the bay enclosure produce corresponding air temperature and air pressure signals. All the sensor signals are input to a processor or controller configured to activate the air control valve and the heater assembly according to set points for temperature and humidity that are specified for the payload in the bay enclosure.

  • Patent number: 8196437
    Abstract: Core rod sections useable for production of finished optical fiber preforms are fabricated by inserting one or more core body pieces axially end-to-end inside a glass cylinder, thereby defining joints between adjacent ones of the inserted pieces. The cylinder is mounted with the contained core body pieces in the region of a furnace. The glass cylinder and core body pieces are heated together in the furnace, thereby elongating the cylinder and the core body pieces contained in the cylinder, and the cylinder collapses to form a finished core rod. Core rod sections are cut from the finished core rod at positions that coincide with the joints between the core body pieces. One or more of the cut core rod sections are useable for the production of optical fiber preforms.

  • Patent number: 8155045
    Abstract: Nodes in a wireless network participate in either point-to-multipoint (PMP) or MANET/mesh communications with other nodes on one or more shared channels of the network. A first or base station node transmits a downlink signal having a time frame structure of determined duration to a number of second or subscriber nodes. Portions of the frame structure establish (i) first time periods during which messages are transmitted from the first node to the second nodes, and (ii) second time periods during which messages are transmitted from the second nodes to the first node, using the PMP protocol on one or more shared channels or subchannels of the network. Other portions of the time frame structure establish third time periods during which nodes communicate with one another using the MANET/mesh protocol on the shared channels or subchannels, while avoiding interference with messages transmitted under the PMP protocol.

  • Patent number: 8049667
    Abstract: An antenna system has N antenna units stacked on a mast. Each unit has elements for responding to, e.g., GPS signals, and a phasing network that produces mutually orthogonal primary and auxiliary pattern modes at corresponding mode ports of the unit. A number of power dividers are each associated with a different mode, and each divider has N input ports coupled to the associated mode port of a corresponding antenna unit. The power divider associated with the primary pattern mode produces a reference beam and an auxiliary beam, and remaining power dividers produce different auxiliary beams. All beams have approximately both a common phase center and a common group delay center. An adaptive processor combines the reference and selected auxiliary beams to obtain a composite antenna reception pattern in which nulls are inserted at certain angles to suppress interfering signals, without degrading authentic signals arriving at other angles.

  • Patent number: 7944559
    Abstract: A hyperspectral imaging system has fore-optics including primary, secondary and tertiary fore-optics mirrors, and an imaging spectrometer including primary, secondary and tertiary spectrometer mirrors. Light from a distant object is collected by the primary fore-optics mirror, and the tertiary fore-optics mirror forms an intermediate object image at an entrance side of a spectrometer slit. The spectrometer mirrors are configured so that light from an exit side of the slit is diffracted by a grating on the secondary mirror, and an image representing spectral and spatial components of the object is formed by the tertiary spectrometer mirror on a focal plane array. The surface of each mirror of the fore-optics and the spectrometer has an associated axis of symmetry. The mirrors are aligned so that their associated axes coincide to define a common system axis, thus making the imaging system easier to assemble and align in relation to prior systems.

  • Patent number: 7924747
    Abstract: A process and system for enhancing connectivity among nodes of a wireless communications network by adapting to changes in the network topology. Nodes of the network are configured to operate according to either (i) an ad hoc protocol wherein a given node assumes a role of a mesh node capable of connecting with other like-configured nodes, or (ii) a point-to-multipoint protocol wherein the given node assumes a role of either a base station, or a subscriber station being served by another node which is assuming the role of a base station. A determination is made as to whether each node should operate according to the ad hoc protocol or the point-to-multipoint protocol, in order to maintain an optimum state of connectivity among all nodes of the network. The determined operating protocol is then implemented for each node.

  • Patent number: 7836728
    Abstract: An optical fiber preform is fabricated by inserting a number of core body pieces end-to-end inside a glass cylinder, wherein the pieces may have a cladding-to-core diameter (D/d) ratio within the range of one to four. The cylinder with the inserted core body pieces is mounted vertically on a furnace and heated so that the cylinder becomes elongated and its outside diameter collapses to form a core rod from which core rod sections with D/d ratios greater than five, can be cut. A soot overcladding is deposited on the circumference of a core rod section until the diameter of the deposited soot builds to a determined value. The core rod section with the deposited soot overcladding is consolidated to obtain a finished optical fiber preform. The preform preferably has a D/d ratio of about 15 or more, and an optical fiber may be drawn directly from the preform.

  • Patent number: 7839321
    Abstract: Ground clutter is effectively separated from true signals echoed by a cable in the flight path of an aircraft, by encoding a transmitted pulse wave in a radar system with at least one transmit (TX) coding sequence, so that received signals echoed by the cable on which the pulse is incident and associated ground clutter are orthogonal or separable from one another. The TX coding sequence is altered into two receive (RX) coding sequences one of which corresponds to the cable and the other to the ground clutter. The two RX coding sequences are then correlated with the received signals, thereby separating the true signals echoed by the cable from the associated ground clutter.
