  • Patent number: 11350853
    Abstract: A method of providing gait coaching is disclosed. Run data is received and stored regarding runs of a broad and diverse population of users, as well as a more narrow set of expert users. A gait metric model is developed for determining an ideal stride length or cadence based on pace and at least one physiological characteristic. Regression coefficients for at the model are determined based on a regression of the run data from the broad and diverse population of users. In contrast, a regression constant for the model is determined based on a regression of the run data from expert users. Using the model, an ideal stride length or cadence for a particular user on a particular run can be determined and utilized to provide useful monitoring, comparison, and feedback to the user regarding his or her stride length or cadence.

The embedded sensors include a three-axis accelerometer, a three-axis gyroscope and an array of pressure sensors. Sensor data detected by the sensors can be received by a mobile computing device, which can analyze the sensor data to identify a pattern related to gait, balance or posture within the sensor data; and apply a statistical/machine learning-based classification to the pattern related to gait, balance or posture to assign a clinical parameter to the pattern characterizing a risk of a slip, trip and fall event.

  • Patent number: 10905359
    Abstract: The present invention relates to an apparatus (100), system (200), method (300), and computer program for distinguishing between active and inactive time periods of a subject. An input unit (110) receives time-dependent activity data (120) (e.g., corresponding to a level of activity). An activity threshold providing unit (130) provides an activity threshold (140) for the subject. An activity assessment unit (150) classifies the time-dependent activity data (120) based on the activity threshold (140). The activity threshold providing unit (130) provides the activity threshold (140) individually for said subject. The present invention provides an approach to patient-tailor the activity threshold (140) for periods of activity and inactivity.

  • Patent number: 10909712
    Abstract: Sets of drones are deployed to create an ad-hoc 5G network in a physical environment to collect sensor data and generate a map of the physical environment in real time. Master drones configured with 5G capabilities are deployed to the physical area to create the 5G ad-hoc network, and swarm drones configured with sensors are deployed to gather environmental data on the physical environment. The gathered data is transmitted to the master drones to generate a map. The deployable 5G network is leveraged to identify precise locations for the swarm drones and each instance of sensor data collected by the swarm drones in order to create an accurate and detailed map of the environment. The map can include information regarding the structural layout of the space and environmental characteristics, such as temperature, the presence of smoke or other gases, etc.

    Abstract: Techniques are disclosed for systems and methods for navigating mobile structures. The mobile structure may include a main attitude & heading reference system (AHRS) and one or more devices. The one or more devices may include a slave AHRS such as a gyroscope. Data may be transmitted from the main AHRS to the one or more devices through a network. Latency may be present in the transmission of data. As such, data from the slave AHRS may be used to determine changes in heading and/or attitude of the mobile structure to compensate for such latency. In addition, such data may be used to determine changes in wind direction and/or heading experienced by the mobile structure.

  • Patent number: 10832122
    Abstract: A method of continuous decoding of motion for a direct neural interface. The method of decoding estimates a motion variable from an observation variable obtained by a time-frequency transformation of the neural signals. The observation variable is modelled using a HMM model whose hidden states include at least an active state and an idle state. The motion variable is estimated using a Markov mixture of experts where each expert is associated with a state of the model. For a sequence of observation vectors, the probability that the model is in a given state is estimated, and from this a weighting coefficient is deduced for the prediction generated by the expert associated with this state. The motion variable is then estimated by combination of the estimates of the different experts with these weighting coefficients.

  • Patent number: 10823755
    Abstract: Embodiments of the present disclosure provide systems and methods that establish non-linear components of gyroscope errors which have not been studied or explored earlier. These errors include but are not limited to non-linear dynamic error which is a function of the angular velocity itself. Bias instability has been observed within the same environment of temperature and atmospheric pressure. In other words, the embodiments of the present disclosure analyse and models static bias errors and dynamic non-linear errors in the gyroscope sensor which may be used to model and correct errors accordingly In subsequent measurements. The system provide solution(s) when there is no way of directly estimating temperature for bias correction of gyroscope, by estimating a temperature change by considering indirect measurements from other sensors present onboard the device.
