  • Patent number: 7312910
    Abstract: A new dispersion managed soliton transmission system where the D map period is the same as the amplifier period and the pulse breathing the in the +D sections of the D maps is approximately symmetrical. Pulse breathing symmetry by one or both of two techniques. In one technique a guiding filter is placed at the beginning of the D map period such that the guiding filter reduces the bandwidth of soliton pulses passing through it by a minimum amount. Consequently, pulse breathing symmetry is restored. The path average pulse energy vs. D behavior of solitons propagating through the D map is changed such that (1) solitons of modest bandwidths have adequate energy at or near D=to provide for error-free transmission over transoceanic distances at or near D=0, and (2) such that the path average pulse energy is nearly independent of D, at or near D=0 for solitons of various pulse widths. The transmission system having this D map is much more tolerant of variations in D and pulse width than the prior art.

  • Patent number: 7196628
    Abstract: A self powered monitoring device for monitoring an animal's temperature and other vital signs. The device may be mounted in the animal's ear, under the animals skin, or in any location which can be used to generate a reliable indication of the animals temperature and other vital signs. The temperature probe for the device is inserted subcutaneously and thermally and/or electrically connected to the housing of the device. Power for the device is provided by a miniature array of solar cells, the power from the solar cells being used to drive digital circuitry which processes signals from the various probes used to gather data concerning the animal's vital signs. The size of the array is chosen to be commensurate with the number of vital signs monitored, with the amount of sunlight, density of herd, and other factors being considered to ensure sufficient power for the device.

  • Patent number: 7034701
    Abstract: A multi-criteria fire detection system, comprising a plurality of sensors, wherein each sensor is capable of detecting a signature characteristic of a presence of a fire and providing an output indicating the same. A processor for receiving each output of the plurality of sensors is also employed. The processor includes a probabilistic neural network for processing the sensor outputs. The probabilistic neural network comprises a nonlinear, nor-parametric pattern recognition algorithm that operates by defining a probability density function for a plurality of data sets that are each based on a training set data and an optimized kernel width parameter. The plurality of data sets includes a baseline, non-fire, fist data set; a second, fire data set, and a third, nuisance data set.

  • Patent number: 6985079
    Abstract: A system is provided for testing and enhancing the alertness of operators who monitor video surveillance imagery. Alertness is tested by displaying any of a variety of visual elements on top of or near the video imagery, and receiving input from human operators in response to the visual elements, via one or more input devices. The system further allows for economic management of human operators by transmitting imagery from many video sources to any number of operators. Video feeds are automatically switched, via software, away from an operator who wishes to take a break or has poor alertness. In this fashion, the system maximizes operator vigilance while also maximizing workflow for all available operators.

  • Patent number: 6906617
    Abstract: The instantaneous power consumption of an appliance is used to determine the status of the appliance, from which further actions may be taken. This invention is premised on the observation that most appliances have a characteristic power consumption pattern that can be used to determine the state of operation of the appliance. An electric coffee pot, for example, consumes high power substantially continuously during the brewing state, then reduces its power level, or power duration, or both, while keeping the pot warm, then terminates its power consumption when it is turned off. In like manner, the power consumption patterns of other appliances, such as toasters, washing machines, dryers, and so on may also be used to determine the state of each appliance. The communicated state may be used by a home-automation system to effect a variety of actions, including notifying the user, terminating the available power to the appliance, initiating an action by another appliance, and so on.

  • Patent number: 6833786
    Abstract: A pneumatic demultiplexer that allows a person with a disability to control multiple assistive technology devices by the use of a single sip-and-puff tube. The devices to be controlled are operated by a single pneumatic or electrical switch input. The pneumatic demultiplexer is under the control of a microprocessor. In a scan stage the user selects the target device via scrolling LED indicators. When a specific device is chosen, the corresponding solenoid valve is activated to connect the input sip-and-puff port to the pneumatic output port. In the activation stage, the input sip-and-puff tube controls the target device directly via the pneumatic demultiplexer. The microprocessor monitors the line activity via a sip-or-puff switch. A watchdog timer is implemented by the microprocessor. After there is a lack of activity for preprogrammed time period, the system switches from the activation stage back to the scan stage.
