| 20120226441 | Sensor Network for Detecting Riverbed Scour - A riverbed scour detection system, comprising a wireless sensor network embedded in areas of potential scour. The scour detection network has one or more vertical stacks of sensor nodes placed in the riverbed at known locations. The sensors detect each other, and non detection of a sensor indicates its removal by scour activity. | 09-06-2012 |

| 20100274488 | Neutrally buoyant sensor apparatus and method for mapping a water pathway - An apparatus and method for mapping a water pathway. A group of sensors can be employed for detecting one or more features associated with the water pathway in a direction of flow through the water pathway. A buoyant vessel maintains the sensors, and the sensors assist in compiling data indicative of the detected features. The velocity in the direction of flow through the water pathway can be then determined based on data indicative of the detected feature(s). A mapping of the water pathway can be thereafter generated utilizing the velocity with respect to the features detected by the sensors. | 10-28-2010 |

| 20100070100 | CONTROL ARCHITECTURE AND SYSTEM FOR WIRELESS SENSING - A wireless control system includes at least one remote actuator unit (RAU) and at least one local sensor units (LSU) or self-powered, wireless sensor (SPWS), and may further include a wireless commissioning system (WCS), which enables associations between devices to be established from a single location. The LSUs, RAUs, and SPWSs are each programmed to operate in harmony with one another by creating associations between each other, each being identifiable by the others using a unique identification number. This association can be accomplished using programming buttons on each type of unit. Alternatively, the associations between devices within a wireless controlled system can be greatly simplified using the WCS. Establishing associations between the various devices permits the devices to interact with each other. The absence of an association between devices prevents the devices from interacting with one another. Each device can be associated with zero, one, or multiple other devices. | 03-18-2010 |
| 20110090046 | CODED WIRELESS KEY CARD SENSOR UNIT - A coded wireless sensor unit has a slot sized to receive a key card. When a key card is inserted into the slot, the act of insertion generates a energy-harvested power pulse, which powers circuitry that reads electrical device control information coded on the key card and creates a first information packet signal that is transmitted by an on-board transmitter. The signal can be read by a receiver and relayed to a control unit which controls certain electrical devices which consume line power in response to received information packet signals. The control unit decodes received information packet signals and either turns on or activates the electrical devices in accordance with the decoded device control information. Removal of a key card can also be used to generate a power pulse, which creates a second information packet signal that is used to turn off or deactivate the electrical devices. | 04-21-2011 |
| 20110272261 | TAMPER-RESISTANT, ENERGY-HARVESTING SWITCH ASSEMBLIES - Tamper-resistant, longer-lasting energy-harvesting switch assemblies that can accommodate longer antennas required for operation in the 315 MHz radio frequency band are provided. In order to accommodate longer antenna that will not fit within the energy-harvesting module, the front major face of the back plate is equipped with a perimetric channel or trough into which a wire antenna can be installed. The problem of rocker wear in prior-art devices caused by abrasive action of the bows is rectified by a redesign of the rocker and the manufacture of a wear-resistant insert that snaps into place at the rear of the rocker. The potential theft problem associated with prior-art devices has been resolved by redesigning the back plate and the retainer clip that engages latches on the redesigned back plate. Non-destructive removal of the retainer clip can be effected only with a special tool. | 11-10-2011 |
| 20110297830 | ULTRA-LOW-POWER OCCUPANCY SENSOR - Passive IR sensor detection circuitry is provided that consumes eighty to ninety percent less power than conventional PIR sensor detection circuitry. Whereas prior art PIR sensor detection circuitry employs multiple amplification stages, to boost the power of the weak sensor signal, and a window comparator to determine whether an occupancy condition exists, the present invention uses, at most, a single amplification stage and no window comparator. In place of multiple amplification stages and a window comparators, the PIR sensor circuitry of the present invention uses a sensitive microcontroller to both detect and process the signal. A peak detector can be added just before the signal—whether amplified or not—is received by the microcontroller. Decay time of the peak detector is adjusted so that the signal will not substantially decay between measurements. | 12-08-2011 |

| 20100155984 | MANUFACTURING ONE-PIECE COMPOSITE SECTIONS USING OUTER MOLD LINE TOOLING - A method for manufacturing composite parts. A temporary removal layer may be placed on an inner mold line tool. A composite material may be laid up on the inner mold line tool for a composite part. The inner mold line tool may be positioned with the composite part inside an outer mold line tool. The composite part and the temporary removal layer may be transferred from the inner mold line tool to the outer mold line tool. The inner mold line tool and the temporary removal layer may be removed from inside of the outer mold line tool after transferring the composite part and the temporary removal layer to the outer mold line tool. | 06-24-2010 |

| 20080243354 | Prediction based engine control system and method - A prediction based engine control system is disclosed. The engine control system may have sensor configured to sense a current engine operation and generate a corresponding signal and a controller in communication with the sensor. The controller may be configured to receive the signal, compare the current engine operation to an allowable range of engine operation, predict a future engine operation based on the signal, and limit current engine operation based on the prediction, even when the current engine operation is within the allowable range of operation. | 10-02-2008 |
| 20090300422 | Analysis method and system using virtual sensors - A method for analyzing operations of a plurality of machines communicating with a server computer. The method may include establishing a plurality of virtual sensors corresponding to a plurality of engine systems of the respective plurality of machines. Each virtual sensor may be indicative of interrelationships between a plurality of input parameters and a plurality of output parameters of an engine system. The method may also include determining an operational accuracy of each virtual sensor, and calculating a score of each machine based on the operational accuracy of a virtual sensor of the machine. Further, the method may include ranking the plurality of machines based upon the score of each machine, scheduling maintenance for a certain number of machines based on the ranking of the plurality of machines, and providing automatic notification of the scheduled maintenance. | 12-03-2009 |
