Abstract: A method includes receiving, at a master agent, announcements from candidate consumer agents indicating the presence of the candidate consumer agents. Each announcement includes display parameters for a display of the corresponding candidate consumer agent. The method further includes receiving at the master agent content parameters from a producer agent, the content parameters defining characteristics of content to be provided by the consumer agent. A mosaic screen is configured based on the received announcements and the content parameters. This configuring of the mosaic screen includes selecting ones of the consumer agents for which an announcement was received and generating content distribution parameters based on the content parameters and the display parameters of the selected ones of the consumer agents. The generated content distribution parameters are provided to the consumer agent.

Abstract: A blood pressure monitoring device includes a patch including two inertial measurement units placed adjacent to the skin of a user. The blood pressure monitoring device includes a control unit coupled to the patch and configured to receive sensor data from the inertial measurement units. The control unit includes an analysis model trained with multiple machine learning processes to generate blood pressure estimations based on the sensor data. A first general machine learning process trains the analysis model with a training set gathered from plurality of other individuals. The second general machine learning process retrains a portion of the analysis model with a second machine learning process utilizing individualized training set gathered from the user.

Abstract: The present disclosure is directed to a device and method for detection of motion events including towing of the vehicle, jacking of the vehicle, and the vehicle being hit by another object. Processing is split between an MCU and a sensor unit. After the vehicle is turned off and before the MCU enters a sleep mode, the MCU calculates a gravity vector of the vehicle using accelerometer data, calculates threshold values based on the gravity vector, and saves the threshold values. After the MCU enters the sleep mode, the sensor unit subsequently monitors and detects motion events with the saved threshold values.

Abstract: A sensor chip includes registers storing and outputting configuration data, an extraction circuit receiving digital data and extracting features of the digital data in accordance with the configuration data, and a classification circuit applying a decision tree to the extracted features to generate a context of an electronic device into which the sensor chip is incorporated relative to its surroundings, the decision tree operating according to the configuration data. The classification unit outputs the context to the registers for storage. The configuration data includes which features for the extraction circuit to extract from the digital data, and a structure for the decision tree. The structure for the decision tree includes conditions that the decision tree is to apply to the at least one extracted feature, and outcomes to be effectuated based upon whether the extracted features meet or do not meet the conditions.

Abstract: An electronic device includes a sensor unit. The sensor unit includes a sensor and low power, low area sensor processing unit. The sensor processing unit performs an unsupervised machine learning processes to learn to recognize an activity or motion of the user or device. The user can request to learn the new activity. The sensor processing unit can request that the user remain stationary for a selected period of time before performing the activity. The sensor processing unit records sensor data while the user performs the activity and generates an activity template from the sensor data. The sensor processing can then infer when the user is performing the activity by comparing sensor signals to the activity template.

Abstract: Technological advancements are disclosed that utilize inertial sensor data for multiple classes to select a combination of filters to extract information though features to train a machine learning core decision tree. A determination is made whether the data for a class includes a frequency peak or dominating frequency that contains significant information about the class. In response to the data for the class including a frequency peak, a peak-based frequency range is determined. An entropy value is calculated for multiple frequency ranges in the data for the class. An entropy-based frequency range is selected from the multiple frequency ranges having a minimum entropy value. A frequency of interest is selected from the peak-based frequency range and the entropy-based frequency range for the class. A combination of filters is selected for each frequency of interest for each class and a decision tree is trained based on selected filter combination.
