Patent number: 11733379Abstract: A robotic cleaning appliance includes a housing, surface treatment item, surface type detection sensor, and processor. The sensor emits sonic signals toward a surface being traversed and receives corresponding returned signals from the surface. The returned signals are used for surface type detection and include directly reflected primary returned signals and multi-path reflected secondary returned signals which return at a later time than the primary returned signals. The processor selects a window of time after transmission of a sonic signal such that the returned signals in the window comprise at least a portion of the secondary returned signals, wherein the window is related to round trip time-of-flight of the returned signals; processes the returned signals falling in the window to achieve a reflectivity metric; compares the reflectivity metric to a stored value; and based on the comparison, determines which surface type of a plurality of surface types has been detected.Type: GrantFiled: July 11, 2022Date of Patent: August 22, 2023Assignee: InvenSense, Inc.Inventors: James Alexander Gordon, David Horsley, Sebastien Riccardi

Patent number: 11381745Abstract: Systems and methods of correcting for signal drift in optical image stabilization of a portable device. An accelerometer is used to obtain an acceleration signal corresponding to acceleration of the portable device. A gravity component is removed from the accelerometer signal to obtain a proper acceleration signal. A double integration is performed on the proper acceleration signal to obtain a translation signal. A drift component of the translation signal is estimated. The estimated drift component is used to generate a drift correction signal. A phase compensation signal is determined based on a plurality of phase responses of a plurality of components of the optical image stabilization system. The drift correction signal and the phase compensation signal are applied to an actuator controller which controls movement of a lens within the portable device as part of the process for optical image stabilization.Type: GrantFiled: January 24, 2020Date of Patent: July 5, 2022Assignee: InvenSense, Inc.Inventors: Pierre Grenet, Sebastien Riccardi, Joe Youssef

Publication number: 20200288061Abstract: An optical image stabilization system and method which also compensate for translation, in addition to rotation compensation. An accelerometer may be used to detect acceleration movement of the camera which may be used to determine translation movement of the camera. In this way, using the acceleration information, a compensation or stabilization may be achieved in each axis based on a translation movement of the camera or the camera-containing device. In an embodiment, the present invention reduces the unwanted signal drift or undesired phase shift due to integration of the accelerometer sensor signal into the resulting translational movement signal. The various contributions to phase delay from the different aspects or portions of the overall system are assessed so a net amount of phase delay may be determined, such that an equal and opposite amount of phase delay may be introduced in order to bring the net phase delay to zero or close to zero.Type: ApplicationFiled: January 24, 2020Publication date: September 10, 2020Inventors: Pierre Grenet, Sebastien Riccardi, Joe Youssef

Publication number: 20180339208Abstract: A method for analyzing the game of a user of a racket (Ra) includes detecting an impact on the racket (Ra) from representative measurements of a shock to the racket (Ra) provided by a sensor assembly comprising at least one sensor sensitive to shocks linked to the racket (Ra) in a fixed manner in terms of movement. A moment of impact is associated with a detected impact, from the measurements transmitted by the sensor assembly.

Patent number: 8884877Abstract: An improved air pointing device which is capable of compensating for the roll angle imparted to said device by a user of said device. The device of the invention includes at least two gyrometers and two accelerometers, the latter being each used for different roll angles. The correction of the roll angle is effected by using the measurements of the first accelerometer, the output of the second accelerometer being simulated as an approximated function of the measurements of the first accelerometer, using a polynomial approximation of the relation between the output of the two accelerometers, the order of the polynomial being chosen as a function of the computing power which is available and the precision which is needed. In an embodiment of the invention, the first and second accelerometers are advantageously swapped at a value of the roll angle which is substantially equal to 45°.Type: GrantFiled: April 29, 2011Date of Patent: November 11, 2014Assignee: MoveaInventors: Yanis Caritu, Sébastien Riccardi, Olivier Neyton
