Innovative Approach to Distributed Energy Resource Scheduling
ActiveUS20140277599A1Minimal operating costProvide powerLoad forecast in ac networkWind energy generationGrid managementElectric power system
The present disclosure provides for distributed resource scheduling performed by an advanced resource scheduling (ARS) module implemented on a distributed grid management (DGM) server in a power system. The ARS module is configured to automatically generate a resource schedule for controllable distributed energy resources (e.g., resources that are remotely controllable by DGM server and ARS module) in a distribution network of the power system, such as power generation resources and energy storage resources, to provide power in a cost-effective (e.g., optimal) manner. The ARS module is configured to take into account the operating limits of the distributed energy resources (DERs), the cost curves of the DERs, the system load demand, and other operating constraints to determine the most economical operating plan for the DERs, using an optimization technique such as the particle swarm optimization (PSO) algorithm.

Method for programming a patient care device
InactiveUS20060106649A1Improve quality of careReduce labor costsCoupling device connectionsDrug and medicationsDrugs labelHospital network
The present invention is directed to a system and method for providing care to a patient, comprising a patient care device having a number of configuration databases stored in a memory in the device. Each configuration database preferably includes protocols, operating limits, rule sets and / or operating features that collectively define an operating environment, or personality, of the device. Selection of a specific configuration database preferably is based at least in part upon patient-specific information obtained from any location in a distributed hospital network. Examples of such patient-specific information include patient age or size, patient medical characteristics, a location of the patient or a location of the care device. In a preferred embodiment, programming a patient care device to deliver a drug to a patient entails activating a configuration database and scanning a machine-readable drug label identifying a particular protocol stored in the activated database. The selected protocol includes default parameters for delivering the drug, and the label optionally includes instructions for deviating from the default protocol.

A method and system for controlling the operation of a vehicle is disclosed that includes a radio frequency transponder and a vehicle configured to respond to data stored in the transponder by preventing or disabling operation of the vehicle under certain conditions indicated by data stored in the transponder. A communications controller receives the data from the transponder, then monitors the operation of the vehicle to make sure it is operated within the limits that are stored in the transponder. By communicating with other controllers on the vehicle that are in charge of other subsystems, it receives information relating to whether the operational limits of the vehicle have been approached or exceeded, and takes appropriate action in that event, the action may include not enabling the vehicle initially, or disabling the vehicle, or causing an operator display to indicate which limit has been exceeded or approached.

Method and system for predicting ship motion or the like to assist in helicopter landing
InactiveUS6064924AAnalogue computers for vehiclesAnchoring installationsShort termsVisual perception
A method for a short-term prediction of future ship motion in open water to furnish visual cueing information that can be remotely presented to a pilot during an aircraft landing is described. Two sets of samples of the sea surface geometry along a radial azimuth line from a ship as a function of elevation of a sensor are first acquired. These are compensated to remove the components due to the ship's motion. Two wave traces are then separately derived in Cartesian format from the two sets of acquired samples. These wave traces are subjected to a Fast Fourier Transform to detect the amplitudes and phases of the individual wavelength components. The direction of the wavelength components is determined using a measure of their phase change in the scan direction during the time interval between the two scans together with their measured wavelength. The amplitude, direction and phase of each component is utilized together with the known motion characteristics of the moving ship in order to derive a short-term prediction of future ship motion in the time domain. A quiescent period of the ship motion is located by comparing the short-term prediction with the pre-defined operating limit criteria. Finally, a message signal is transmitted to the pilot of the aircraft indicating Time-to-Land and the duration of the quiescent period.
