Abstract: The present disclosure is directed to an air filter sensor system that can monitor a status of a filter and provide information to a remote system regarding the filter's status. The system can receive, by a computing server via one or more computer networks and from each of a plurality of sensor assemblies coupled to a corresponding plurality of air filters, information indicative of filter contamination levels respectively associated with each corresponding air filter of the plurality of air filters. Each of the respective filter contamination levels being provided by one sensor assembly of the plurality of sensor assemblies based at least in part on a difference in detected air pressure between first and second sides of the corresponding air filter. The system tracks the respective filter contamination levels over a first period of time and determines, by the computing server and based at least in part on the tracking of the respective filter contamination levels, a schedule for one or more maintenance events associated with a first air filter of the plurality of air filters.

Abstract: A child safety seat may include a motion sensor, e.g., an accelerometer, and a pressure sensor, e.g., a air pressure sensor. The motion sensor is configured to detect a motion state of a vehicle where the child safety seat is installed, e.g., whether the vehicle is moving or non-moving. The pressure sensor is configured to detect a motion state of a door of the vehicle, e.g., a door open/close motion. Based on the information detected by the motion sensor and the pressure sensor, a controller determines whether an awareness scenario occurs.

Abstract: The present disclosure is directed to a device with enhanced human activity recognition. The device detects a human activity using one more motion sensors, and enhances the detected human activity depending on whether the device is in an indoor environment or an outdoor environment. The device utilizes one or more electrostatic charge sensors to determine whether the device is in an indoor environment or an outdoor environment. The device may also exclude gyroscope data when performing human activity recognition, and instead utilize electrostatic charge variation data in conjunction with acceleration data to perform human activity recognition.

Abstract: A computing system includes a first hardware element having a first accelerometer and a first gyroscope, and a second hardware element having a second accelerometer and a second gyroscope. The first and second hardware elements are moveable with respect to each other. The computing system recursively generates a result signal indicative of a relative orientation of the first and second hardware elements with respect to each other. The result signal may be generated by generating a first intermediate signal indicative of a angle between the first and second hardware elements based on signals generated by the first and second accelerometers and generating a second intermediate signal indicative of the angle based on signals generated by the first and second gyroscopes. The result signal indicative of the angle may be generated as a weighted sum of the first intermediate signal and the second intermediate signal. At least one of the first and second hardware elements is controlled by on the result signal.
