  • Publication number: 20110071078
    Abstract: The present invention features methods and compositions for treating a patient who has a neurological deficit. The method can be carried out, for example, by contacting (in vivo or in culture) a neural progenitor cell of the patient's central nervous system (CNS) with a polypeptide that binds the epidermal growth factor (EGF) receptor and directing progeny of the proliferating progenitor cells to migrate en masse to a region of the CNS in which they will reside and function in a manner sufficient to reduce the neurological deficit. The method may include a further step in which the progeny of the neural precursor cells are contacted with a compound that stimulates differentiation.

  • Patent number: 7907019
    Abstract: A method for operating a micro-electro-mechanical system (MEMS) scanner on a resonant mode frequency is provided. The method includes generating a drive signal for a MEMS scanner. A sensor signal is received from the MEMS scanner. The drive signal is compared to the sensor signal. An accumulated correction signal is generated based on the comparison of the drive signal and the sensor signal. The drive signal for the MEMS scanner is then adjusted based on the accumulated correction signal.

  • Publication number: 20100321750
    Abstract: A method for providing feed forward compensation in a drive signal for a rapid resonant frequency change due to a rapid LASER intensity change upon a micro-electro-mechanical system (MEMS) mirror and/or a surrounding MEMS structure in a MEMS scanner causing a mirror temperature change is provided. The method includes determining an intensity factor for at least one laser beam projected onto the MEMS scanner and adjusting a drive frequency of the drive signal based on the intensity factor. The intensity could represent a single intensity factor for multiple laser beams projected onto the MEMS scanner. The method could also include delaying the adjustment of the drive frequency to allow the resonant frequency change to take affect in the MEMS scanner. Delaying the adjustment could include delaying delivery of the intensity factor such that the intensity factor is provided coincident with the resonant frequency change of the MEMS scanner.

  • Patent number: 7839900
    Abstract: An architecture for a frequency hopped spread-spectrum transmitter-receiver in an advanced tactical data link packet switched network that ensures optimal Statistical Priority-based Media Access (SPMA) performance, enables more efficient packing of hop channels in a given allocated bandwidth and counteracts hostile jamming. The transmitter-receiver supports a scalable symbol rate mode that reduces the symbol rate in the time domain and decreases the bandwidth in the frequency domain, over a predetermined prior value. A transceiver according to the present architecture is able to statically or dynamically scale the symbol rate of transmissions, operate in burst mode and change the hop set. In one embodiment the transceiver is part of a Software Defined Radio (SDR).

  • Publication number: 20100288764
    Abstract: A packaging membrane comprising a laminate of at least first and second layers, having a removable portion formed by substantially coincident first and second score lines, the first score line being formed in the first layer but not breaching the second layer, and the second score line being formed in the second layer but not breaching the first layer. Optionally, a third layer is disposed between the first and second layers, and the third layer is not breached by either score line. In the removable portion, an adhesive-free region is provided within which the first layer is not adhered to the underlying layer(s). An integral tab is defined in the first layer within the adhesive-free region, the tab being formed by a cut line in the first layer. The tab is located entirely inside the first and second score lines and does not project beyond any edge of the membrane.

  • Patent number: 7826372
    Abstract: A process for use in conjunction with a communications network routing protocol that automatically adjusts for congestion that may occur due to the presence of advantaged and partially disadvantaged nodes. The network nodes check to determine if they are advantaged or partially disadvantaged. Advantaged nodes may, for example, be airborne or satellite nodes having a high degree of network connectivity. Partially disadvantaged nodes may comprise nodes that are low on power. Advantaged nodes and partially disadvantaged nodes adjust the network metrics entered into the routing tables they use to advertise their routing information over the network to show longer pathways through such nodes. As a result the other nodes in the network reduce the amount of network traffic routed through advantaged and disadvantaged nodes.

  • Patent number: 7813324
    Abstract: A method for handling data transmission errors in a wireless communication network includes receiving a first data from a first node at a second node using a data transmission protocol having a first slot for transmitting the first data. The first slot includes a plurality of bits and a first slot header comprising an acknowledgment request for at least one group of bits. The method also includes evaluating the first set of data for errors and generating a second slot using the data transmission protocol. The second slot includes at least a second slot header comprising acknowledgement data in response to the acknowledgement request. The acknowledgement data has a structure based on a Forward Error Correction (FEC) protocol block size. The second slot is then transmitted to the first node.

  • Publication number: 20100166200
    Abstract: A method and apparatus for detecting a singing frequency in a signal processing system using two neural-networks is disclosed. The first one (a hit neural network) monitors the maximum spectral peak FFT bin as it changes with time. The second one (change neural network) monitors the monotonic increasing behavior. The inputs to the neural-networks are the maximum spectral magnitude bin and its rate of change in time. The output is an indication whether howling is likely to occur and the corresponding singing frequency. Once the singing frequency is identified, it can be suppressed using any one of many available techniques such as notch filters. Several improvements of the base method or apparatus are also disclosed, where additional neural networks are used to detect more than one singing frequency.

  • Patent number: 7680092
    Abstract: A method of selecting linked metric measurements from at least one of open loop and closed loop measurements is disclosed. The method includes sending by a first node a first radio communication and receiving by a second node the first radio communication over a communication link.

The link metric measurements are at least one of symbol error rate (SER), packet error rate (PER), frame error rate (FER), bit error rate (BER), signal to noise ration (SNR), and received signal strength (RSS). The method also includes the use of the above link metric measurements by the second node as Open Loop metrics and the sending back of these metrics to the first node for use a Closed Loop metrics by the first node. The method also includes categorizing the dynamics of the communications channel into one of at least two groups based on the estimate.
