A monitoring system that is configured to monitor a property is disclosed. The monitoring system includes a sensor that is configured to generate sensor data that reflects an environmental condition of the property and an electrical monitoring device coupled to an electrical cord that provides power to an electrical device located at the property. The electrical monitoring device is configured to generate electrical data that reflects electricity that flows through the electrical cord. The monitoring system includes a monitor control unit that is configured to: receive, from the sensor, the sensor data; receive, from the electrical monitoring device, the electrical data; and analyze the sensor data and the electrical data. The monitor control unit is configured to: based on analyzing the sensor data and the electrical data, determine a status of the electrical device; and based on the status of the electrical device, perform a monitoring system action.

Electrical appliance power monitoring

A circuit for direct current (DC) offset estimation comprises a quantile value circuit and a signal processor. The quantile value circuit determines a plurality of quantile values of an input signal and includes a plurality of quantile filters. Each quantile filter includes a comparator, a level shifter, a monotonic transfer function component, and a latched integrator. The comparator compares the input signal and a quantile value. The level shifter shifts the output of the comparator. The monotonic transfer function component determines the magnitude of the shifted signal and provide a transfer function signal. The latched integrator suppresses transient characteristics of the transfer function signal and provide the quantile value. The signal processor is configured to calculate a weighted average of the quantile values to yield a DC offset estimate.

Density function centric signal processing

Systems, methods, and techniques for detecting the recording activity of a sensor are described. A monitoring system includes a sensor that is configured to generate sensor data, as well as a failsafe circuit that is configured to monitor an electronic signal of the sensor and determine that the sensor is recording. The system can further include a control unit that receives indication from the failsafe circuit that the sensor is recording and, based on determining that the control unit did not request the sensor to record or that the control unit is not aware that the sensor is recording, the system outputs a signal, e.g. to an indicator light, indicating that the sensor is recording.

Recording activity detection

A monitoring system that is configured to monitor a property is disclosed. In one aspect, the monitoring system includes a sensor that is located at the property and that is configured to generate sensor data. The monitoring system further includes a voltage sensor that is configured to generate voltage data by measuring voltage at an electrical outlet located at the property. The monitoring system further includes a monitor control unit that is configured to receive the sensor data; receive the voltage data; determine an action of an electrical device that is located in the property or that is located at a neighboring property in a vicinity of the property; determine whether the electrical device is located at the property or at the neighboring property in the vicinity of the property; and perform a monitoring system action.

Voltage event tracking and classification

Scene and/or state information may be used to facilitate processing an input to separate one or more signals within the input, to shape the signal within the input, and/or for other processing of the input or signal(s) within the input. A scene determination may be made based upon location data, time data, data describing the received input, or other basis. A state determination may be made based upon the scene determination, properties of a signal itself, or other information such as location, time, etc. By determining an appropriate scene and/or state, processing of an input and/or a signal within an input may proceed in a fashion determined to provide the most valuable information for output. Systems and methods in accordance with the invention may be implemented in a wide variety of baseband processing systems, such as hearing aids and energy consumption monitoring systems.

Scene and state augmented signal shaping and separation

Systems and techniques enable monitoring one or more devices connected to an electrical power distribution system. In some implementations, a probe waveform is injected into a circuit of an electrical power distribution system. An output signal of the injected probe waveform is extracted from the circuit of the electrical power distribution system and, based on the extracted output signal of the injected probe waveform, dispersion values for the branch circuit are determined. The dispersion values indicate a variation of magnitude of an impedance of the branch circuit across different values of phase of the impedance. Based on the dispersion values for the branch circuit, at least one characteristic of a device connected to the branch circuit is determined. An association between the at least one characteristic of the device connected to the branch circuit and the corresponding dispersion values is stored in at least one computer memory.

Monitoring of electrical appliances based on dispersion of impedance

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing actions based on a determined relative composition of light. In some implementations, data representing an amount of ambient light detected within the portion of the property by a light sensor located at the portion of the property is initially obtained. Data indicating (i) a shape of an optical spectra for a natural light source, and (ii) a shape of an optical spectra for a non-natural light source is then obtained. A relative composition of the ambient light detected within the portion of the property is determined. An estimated amount of natural light within the portion of the property is then determined. In response, the amount of light output by one or more light sources located at the portion of the property is adjusted.

Light controller

A system for classifying impulsive noise on a communications signal comprises an impulse signal generator, an integrator, a first comparator, and an impulse peak detector. The impulse signal generator receives a communications signal that includes impulsive noise and is configured to provide an impulse signal that includes just the impulsive noise. The integrator receives the impulse signal and integrates the impulse signal to determine the power of the impulse signal. The first comparator receives the impulse signal and is configured to compare the impulse signal to a first reference signal and indicate the time during which the value of the impulse signal is greater than the value of the first reference signal. The impulse peak detector receives the impulse signal and is configured to process the impulse signal, compare the processed signal to a second reference signal, and detect the peak value of the impulse signal.
