20110032139 | METHOD FOR HUMAN ONLY ACTIVITY DETECTION BASED ON RADAR SIGNALS - A method of detecting human presence includes using a radar sensor to monitor a space, and receiving an output signal from the radar sensor. A Fourier transform is performed on the output signal to produce a signal spectrum. It is decided whether the output signal is indicative of human activity dependent upon at least one acoustic feature of the signal spectrum and at least one spectral feature of the signal spectrum. | 02-10-2011 |
20110032826 | METHOD AND SYSTEM FOR DEPLOYING AND EVALUATING NETWORKS IN INDOOR ENVIRONMENTS - A method for deploying and evaluating a network system includes providing an electronic two- or three-dimensional representation of a layout of a building, placing a plurality of nodes of the network system in the building, and communicatively coupling the nodes together to form the network system. The nodes are inspected dependent upon a regulatory requirement and/or the representation of the layout of the building. The network is evaluated dependent upon data collected during the inspecting and dependent upon a network protocol design and/or an interference model. The inspecting of the nodes and the evaluating of the network are performed automatically by use of at least one electronic processor. | 02-10-2011 |
20110144819 | METHOD FOR NON-INTRUSIVE LOAD MONITORING USING A HYBRID SYSTEMS STATE ESTIMATION APPROACH - A method for non-intrusively monitoring a load including a plurality of appliances includes retrieving a plurality of mathematical models for modeling operation of a respective subset of the appliances. A value of a respective operational parameter is predicted for each of the subsets of appliances. An output of the load is measured. A respective value of each of the operational parameters is calculated based on the mathematical models and the outputs of the load. The predicting, measuring and calculating steps are repeated until a metric pertaining to a difference error between the measured output and the predicted output calculated from the operational parameter and the mathematical models is equal to or below a threshold for one of the subsets of appliances. It is decided that the one subset of appliances is currently operating whose metric pertaining to a difference error is equal to or below the threshold. | 06-16-2011 |
20110190594 | DEVICE AND METHOD TO MONITOR, ASSESS AND IMPROVE QUALITY OF SLEEP - A medical sleep disorder arrangement integrates into current diagnosis and treatment procedures to enable a health care professional to diagnose and treat a plurality of subjects suffering from insomnia. The arrangement may include both environmental sensors and body-worn sensors that measure the environmental conditions and the condition of the individual patient. The data may be collected and processed to measure clinically relevant attributes of sleep quality automatically. These automatically determined measures, along with the original sensor data, may be aggregated and shared remotely with the health care professional. A communication apparatus enables the healthcare professional to remotely communicate with and further assess the patient and subsequently administer the treatment. Thus, a more accurate diagnosis and more effective treatment is provided while reducing the required clinician time per patient for treatment delivery. | 08-04-2011 |

20120083930 | ADAPTIVE LOAD MANAGEMENT: A SYSTEM FOR INCORPORATING CUSTOMER ELECTRICAL DEMAND INFORMATION FOR DEMAND AND SUPPLY SIDE ENERGY MANAGEMENT - A method for determining an amount of electricity to purchase includes determining electrical power consumption characteristics of an electrical load at an end user of the electricity. A preference of the end user for an output of the electrical load is ascertained. The output varies with a rate of electrical power consumption by the load. A mathematical model is created of an amount of electrical power to be consumed by the load as a function of time and of monetary cost of the electricity. The model is dependent upon the electrical power consumption characteristics of the electrical load and the preference of the end user for an output of the electrical load. An amount of electricity is purchased based on the mathematical model of an amount of electrical power to be consumed by the load, and based on the monetary cost of the electricity. | 04-05-2012 |
20130041856 | METHOD FOR DETECTION OF MOVEMENT OF A SPECIFIC TYPE OF OBJECT OR ANIMAL BASED ON RADAR SIGNALS - A method of detecting movement includes using a radar sensor to monitor a space, and receiving an output signal from the radar sensor. A Fourier transform is performed on the output signal to produce a frequency domain signal spectrum. The frequency domain signal spectrum is transformed into an acoustic domain signal. It is decided whether the output signal is indicative of movement of a predetermined object or a non-human animal dependent upon at least one feature of the acoustic domain signal and at least one spectral feature of the signal spectrum. | 02-14-2013 |
20130158908 | Method for Unsupervised Non-Intrusive Load Monitoring - A method distinguishes electrical signals corresponding to an activation or deactivation of a single electrical power consuming device from an electrical signal that supplies electricity to multiple electrical power consuming devices has been developed. The method includes generating signatures corresponding to activation and deactivation of a plurality of electrical devices from a transformation of an electrical power signal using sparse deconvolution to cluster and then identify the activation and deactivation of one of the plurality of electrical devices. | 06-20-2013 |
20140172758 | PERSONAL EMERGENCY RESPONSE SYSTEM BY NONINTRUSIVE LOAD MONITORING - A method for a personal emergency response system includes receiving output signals of a nonintrusive load monitoring (NILM)system coupled to an electrical supply of an person's residence, the output signals indicating switching events of appliances connected to the electrical supply. A computer processor is then used to process the output signals in accordance with a machine learning algorithm to identify appliance activation routines.
