Abstract: The present disclosure is directed to lift-up gesture detection for electronic devices. An initial lift-up gesture is detected in response to an orientation change and a lift-up motion of the device being detected. The initial lift-up gesture is validated as a true lift-up gesture in a case where a shaking motion of the device is not being detected when the initial lift-up gesture is detected. If a shaking motion of the device is detected when the initial lift-up gesture is detected, the initial lift-up gesture is rejected.

Abstract: An example gesture detection method includes detecting at a first time a first touch on a touch panel, where the first touch covers a first area of the touch panel, and then determining whether the first touch is within a track region that surrounds a fingerprint sensing region. The method includes determining whether the first touch is within the fingerprint sensing region, the fingerprint sensing region including a sensing surface of a fingerprint sensor. The method includes determining a first fraction of the fingerprint sensing region covered by the first touch and determining whether the first fraction exceeds a first threshold. The first threshold is a majority of the fingerprint sensing region. The method includes determining a second fraction of all of the first area that is within the fingerprint sensing region and determining whether the second fraction exceeds a second threshold, where the second threshold is a fraction indicative of a majority of an area associated with the corresponding touch. The method includes based on determining that the second fraction exceeds the second threshold, determining whether the first touch is valid.

Abstract: A method of operating a touch screen panel includes initiating a communication between the panel and an active pen and determining a touch zone of the panel. The touch zone includes communication channels that are operating by touch while bi-directional communication is occurring between the panel and active pen. Communications channels within the touch zone are disabled and communication between the panel and the active pen can occur while the communications channels within the touch zone are disabled. When it is determined that the communication between the panel and the active pen has stopped, communications channels continue to be disabled within the touch zone for a set time delay while no communication occurs between the panel and the active pen. After the set delay time, the communication channels within the touch zone are enabled.

Abstract: A MEMS (MicroElectroMechanical System) device includes: a supporting body; a movable mass, constrained to the supporting body by flexures so as to be able to oscillate in a main direction; an actuator device, configured to apply to the movable mass an electrostatic actuation force, transverse to the main direction; and a control circuit configured to detect stiction conditions, in which the movable mass is stuck to the supporting body by a stiction force, and for driving the actuator device in response to recognition of the stiction conditions. The actuation force is a variable force with an actuation frequency band containing at least one resonance frequency in a direction transverse to the main direction of a mechanical system comprising the movable mass stuck to the supporting body.

Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected configuration information. The user-selected configuration information includes code generation strategy selections. A configuration store is generated based on the user's selections, and includes a code generation strategy parameters file. The configuration store and the user selected configuration information is utilized to generate the content, such as code, data, parameters, settings, etc. When the content is provided to the programmable computing device, the content initializes, configures, or controls one or more software and hardware aspects of the programmable computing device.

Abstract: A method for determining whether an electronic device is located on a stationary surface includes generating, by a first motion sensor of an electronic device, first sensor data over an acquisition time window. The method includes determining, by a first feature detection circuit of the electronic device, at least one first orientation-independent feature for the acquisition time window based on the first sensor data. The method further includes executing, by a first classifying circuit of the electronic device, a first machine learning classification to determine whether the electronic device is steady or is in motion. And the method further includes, in response to determining the electronic device is steady, executing, by a second classifying circuit of the electronic device, a second machine learning classification to determine whether the electronic device is on a stationary surface or is on a semi-stationary surface based on the at least one first orientation-independent feature.

Abstract: A method includes generating, by a first motion sensor of an electronic device, first sensor data over an acquisition time window; generating first process data by processing the first sensor data to determine whether or not the electronic device is located on a stationary surface; determining whether or not the electronic device is in a stable state based on the first process data. The stable state is indicative of whether the electronic device has remained on a stationary surface or not for a first predefined time. The method includes stopping the processing of the first sensor data in response to determining that the electronic device has been in the stable state for a second predefined time.
