Abstract: According to an embodiment, a first aspect relates to a method for testing a scan chain. The method includes segmenting the scan chain into two or more segments; adding a respective multiplexer at end points of each segment, wherein each pair of sequential segment shares a common multiplexer in between; asserting a select signal at a select terminal of the multiplexers such that a relative position of the two or more segments is rearranged positionally in a rearranged scan chain; generating a test pattern to be communicated to an input terminal of the rearranged scan chain and observing a test result at an output of the rearranged scan chain; and determining a fault condition in the rearranged scan chain based on comparing the test result and an expected result.

Abstract: Methods, systems, and devices for fault detection at pulse width modulation converters are described. An example of one such method includes receiving a first signal including a first pulse width modulation waveform. The first signal may be for controlling a switching component via a first node. A second signal may be received. The second signal may include a second pulse width modulation waveform. The second signal may be output by a second node of the switching component. One or more operations may be performed to compare the second signal with one or more other signals or one or more thresholds. A third signal may be transmitted based at least in part on the comparison of the second signal with the one or more other signals or thresholds. The third signal may indicate whether a fault has occurred at the switching component.

Abstract: The present disclosure relates to a method of training a neural network using a circuit comprising a memory and a processing device, an exemplary method comprising: performing a first forward inference pass through the neural network based on input features to generate first activations, and generating an error based on a target value, and storing the error to the memory; and performing, for each layer of the neural network: a modulated forward inference pass; before, during or after the modulated forward inference pass, a second forward inference pass based on the input features to regenerate one or more first activations; and updating one or more weights in the neural network based on the modulated activations and the one or more regenerated first activations.

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.
