Patent number: 11016610Abstract: Facilitating dynamic adjustment of a click/unclick threshold corresponding to a force-based tactile sensor is presented herein. A system can comprise a tactile sensor comprising force-based sensor(s); and a motion detection component that can determine a rate of change of a movement that has been detected via a group of sensors comprising the force-based sensor(s), and based on the rate of change of the movement, modify a defined sensitivity of the force-based sensor(s) with respect to detection of a click and/or unclick event corresponding to the tactile sensor. Further, the motion detection component can decrease the defined sensitivity with respect to detection of the click and/or unclick event in response to the rate of change being determined to satisfy a defined condition representing an increase in the speed at which the stylus or the finger has moved across the tactile sensor.Type: GrantFiled: April 13, 2020Date of Patent: May 25, 2021Assignee: SENSEL, INC.Inventors: Tomer Moscovich, Ilya Daniel Rosenberg

Patent number: 11010991Abstract: A system for automatically detecting an operational event for a bulk material hauler vehicle. The system includes a sensor mounted on the bulk material hauler vehicle, which is adapted for hauling a bulk material such as an aggregate. The system further includes a telematics system provided on the bulk material hauler vehicle. The telematics system includes a processor running software (or executing instructions or code) for detecting the operational event (e.g., providing functions of a load and unload detection module or discriminator as described herein). During vehicle operations, the sensor transmits sensor data to the telematics system, and the detecting of the operational event includes retrieving a signature definition for the operational event and then verifying the sensor data meets requirements of the signature definition. In some embodiments of the system, the operational event is loading the bulk material on or unloading the bulk material from the vehicle.Type: GrantFiled: December 31, 2018Date of Patent: May 18, 2021Assignee: Command Alkon IncorporatedInventors: Jeremy D. Helms, Michael J. Sobel, Dale L. Sproul, Jeffrey L. Wheeler

Patent number: 10976150Abstract: 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.Type: GrantFiled: May 23, 2018Date of Patent: April 13, 2021Assignee: STMicroelectronics S.r.l.Inventors: Alberto Zancanato, Michele Ferraina, Federico Rizzardini, Stefano Paolo Rivolta

Patent number: 10952671Abstract: The present invention provides a system for monitoring a physiological parameter of players engaged in a sporting activity. The system includes a plurality of reporting units, a controller, and a signaling device. The reporting unit has an arrangement of sensing devices that measure the physiological parameter of an individual player and generate parameter data. The controller receives the parameter data transmitted from each reporting unit and then processes the parameter data to calculate a parameter result. When the parameter result exceeds a predetermined value, the controller communicates with a signaling device that provides an alert to sideline personnel to monitor the player(s) in question. The system also includes a remote storage device for holding historical data collected by the system which permits subsequent analysis.Type: GrantFiled: May 20, 2019Date of Patent: March 23, 2021Assignee: Riddell, Inc.Inventors: Richard M.

Patent number: 10905359Abstract: 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.Type: GrantFiled: June 13, 2016Date of Patent: February 2, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Chevone Marie Barretto, Rita Priori
