    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.

  • 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: 10521733
    Abstract: One or more braking event detection computing devices and methods are disclosed herein based on fused sensor data collected during a window of time from various sensors of a mobile device found within an interior of a vehicle. The various sensors of the mobile device may include a GPS receiver, an accelerometer, a gyroscope, a microphone, a camera, and a magnetometer. Data from vehicle sensors and other external systems may also be used. The braking event detection computing devices may adjust the polling frequency of the GPS receiver of the mobile device to capture non-consecutive data points based on the speed of the vehicle, the battery status of the mobile device, traffic-related information, and weather-related information. The braking event detection computing devices may use classification machine learning algorithms on the fused sensor data to determine whether or not to classify a window of time as a braking event.

  • Patent number: 10512423
    Abstract: The invention relates to an electronic device for estimating energy consumption of a person. The electronic device uses a mathematical model based on acceleration data for estimating the person's energy consumption as a function of the actual performed activity and acceleration values. The acceleration values are converted to an estimate of energy consumption of a given activity by scaling a value of time integrated acceleration data with an activity scaling parameter. The activity scaling parameters for different activities have been determined off-line by comparing measured energy consumptions over e.g. a day with estimated energy consumptions over the same period, where the estimated values are determined using the mathematical model.

  • Patent number: 10466054
    Abstract: The present invention relates to a method for estimating a relative angle (?) between heading (X10) of a person (10) and heading (X12) of a mobile device (12) carried by the person. A first estimate of the relative angle is determined using a multi-axis accelerometer (18) of the mobile device. A second estimate of the relative angle is determined using a multi-axis gyroscope (20) of the mobile device. The first estimate and the second estimate are then combined to provide a combined estimate of the relative angle (?) between the person's heading and the mobile device's heading. The present invention also relates to a system for estimating a relative angle (?) between heading (X10) of a person (10) and heading (X12) of a mobile device (12) carried by the person.

  • Patent number: 10445464
    Abstract: A computer-implemented method is provided including receiving sensor data from a mobile device corresponding to a first user. A user state of the first user is predicted based on the sensor data. A request is transmitted to the first user to confirm the predicted user state, and a notification is transmitted regarding the predicted user state to a second user responsive to the first user's confirmation of the predicted user state or the first user's failure to respond to the request. A computing system for monitoring and reporting activity of a mobile device is also provided.

  • Patent number: 10416758
    Abstract: In an information processing apparatus, a posture data acquiring section acquires output values from a motion sensor of a head-mounted display. Effective rates of acceleration are then obtained by correcting the output values based on correction formulas. A posture is calculated in reference to the axes of the motion sensor based on the acquired rates of acceleration. Thereafter, the posture of the head-mounted display is calculated by performing rotation correction based on previously acquired angle errors, the calculated posture being output to an information processing section. A correction data updating section acquires posture information based on markers of the head-mounted display imaged in a captured image, and updates correction data for use in acquiring the posture from the sensor output values through comparison with the marker-based posture information.

  • Patent number: 10405038
    Abstract: Disclosed are systems, methods, and apparatus for communicating hardware generated video between two or more devices. The devices can operate to mimic chance interactions, or “stop-and-chats,” that normally occur when two or more persons are living together or otherwise in the same locations. For example, each computer or circuit can determine whether a person is proximate to the computer. If two persons that designate each other as connections are simultaneously proximate to their respective devices, a video hardware connection will be created between their computers. Furthermore, respective circuitry can be connected to a third device associated with a person who is proximate to their respective device and also indicated as a connection by both of the two persons who are already connected. A video hardware connection can disconnect when one person participating in the video is no longer proximate to their respective device.
