In a method for training a gesture recognition model, gesture data is collected from an inertial measurement unit (IMU) positioned on one side of a user, wherein the IMU is capable of collecting data when positioned on either side of the user. A transformation is applied to the gesture data, wherein the transformation generates transformed gesture data that is independent of either side of the user. A gesture recognition model is trained using the transformed gesture data.

Training a gesture recognition model using transformed gesture data

In a method for operating a fingerprint sensor including a plurality of ultrasonic transducers, receiving a plurality of images corresponding to different subsets of the ultrasonic transducers of the fingerprint sensor are received, wherein the plurality of images are non-adjacent. For each image of the plurality of images, it is determined whether the image of the plurality of images is indicative of a fingerprint. Provided a number of images of the plurality of images that are indicative of a fingerprint satisfies a threshold, it is determined whether the images of the plurality of images that are indicative of a fingerprint are collectively indicative of a fingerprint. Provided the plurality of images are collectively indicative of a fingerprint, it is determined that the plurality of images include a fingerprint.

Operating a fingerprint sensor comprised of ultrasonic transducers

In a method for operating a fingerprint sensor comprising a plurality of ultrasonic transducers, a first subset of ultrasonic transducers of the fingerprint sensor are activated, the first subset of ultrasonic transducers for detecting interaction between an object and the fingerprint sensor. Subsequent to detecting interaction between an object and the fingerprint sensor, a second subset of ultrasonic transducers of the fingerprint sensor are activated, the second subset of ultrasonic transducers for determining whether the object is a human finger, wherein the second subset of ultrasonic transducers comprises a greater number of ultrasonic transducers than the first subset of ultrasonic transducers.

In a method for operating a fingerprint sensor, a fingerprint capture operation is performed on a fingerprint of a finger contacting the fingerprint sensor. A finger lift action is detected. It is determined whether a latent fingerprint remains on a contact surface of the fingerprint sensor subsequent the finger lift action. If it is determined that a latent fingerprint remains on the contact surface of the fingerprint sensor subsequent the finger lift action, instruction on addressing the latent fingerprint is provided.

Latent fingerprint detection

In a method for generating an estimated fingerprint image, a ridge/valley pattern of a fingerprint of a finger is received. A sensor image including a partial fingerprint of the finger is received. Ridge/valley characteristics of the fingerprint are extracted from the sensor image including the partial fingerprint. An estimated fingerprint image is generated based at least on the ridge/valley pattern of the fingerprint and the ridge/valley characteristics of the fingerprint.

Method for determining the orientation of the trajectory followed by a pedestrian, associated with a trajectory frame, with respect to a reference frame is provided. At least one motion sensor associated with the pedestrian generates data representative of the motion of the sensor housing on the basis of said sensor assembly in the reference frame. A first rotation transformation operator representative of the orientation of the reference frame with respect to the trajectory frame is calculated. The data representative of the motion after transformation by said first operator exhibits at least one characteristic of a set of characteristics which are representative of signals of walking or running motion of a pedestrian and are expressed in the pedestrian frame.

A remote control, such as a 3D air mouse, includes motion sensors used to measure position/orientation in space to alternatively control a cursor on a display, recognize gestures by the user so that data/commands can be entered into an electronic system being controlled or the like. Timed sequences of pressing a single trigger button and the quantity of motion during said sequences are both timed in relation to thresholds to switch between modes.

A method for synchronizing data provided by an image sensor and a motion sensor rigidly linked together, comprising the steps of:

Systems and methods for synchronizing sensor data

A system determines parameters representing the orientation of a solid in movement within a first vector field and a second vector field. A first triaxial sensor and a second triaxial sensor are connected to the solid and measure the components of the respective vector fields along the axes of the sensors, obtaining corresponding first and second vectors. A processor determines the rotation matrix of the solid, using a correction module for delivering a first corrected vector, and calculating a third vector which is not coplanar to the plane formed by the first corrected vector and the second vector, such that the angles of the axis system formed by the third vector and the first corrected vector and the second vector remain constant.
