  • Publication number: 20210133952
    Abstract: An electronics system may include a substrate, an electronic device bonded to the substrate, a plurality of photoluminescent particles disposed on the electronic device, an illuminator, a sensor, and a control module. The illuminator can illuminate the electronic device. The sensor can capture a first set of positions of the photoluminescent particles on the electronic device when the electronic device is not operating under a load and a second set of positions of the photoluminescent particles when the electronic device is operating under a load. The control module can determine thermomechanical stress on the electronic device based at least in part on a difference between the first set of positions and the second set of positions.

  • Patent number: 9690438
    Abstract: A processing system for an input device having a sensing region overlapping an input surface and an array of sensor electrodes configured to form a plurality of proximity pixels and a plurality of force pixels. The processing system is configured to: determine a proximity image indicative of positional information for input objects; determine a force image indicative of local deflection of the input surface in response to force applied by the input objects; determine a respective group of proximity pixels from the proximity image corresponding to each input object; determine a respective group of force pixels from the force image corresponding to each determined group of proximity pixels; determine the position of each input object based on the determined groups of proximity pixels; and determine the force associated with each input object based on the determined groups of force pixels.

  • Patent number: 9569029
    Abstract: A method for face detection management includes determining, for a first time, a presence of an input object in a sensing region of a capacitance input device. The presence is determined for the first time using a first baseline, and the input object satisfies a size threshold. The method further includes suppressing a reporting of capacitance input device during a predefined time period based on the presence of the input object, determining a disabled state of a display of a host, wherein the disabled state is in response to determining the presence of the input object for the first time, and determining, in response to an elapse of the predefined time period and for a second time, an absence of the input object in the sensing region. The absence of the input object is determined for the second time using a second baseline to account for the disabled state of the display. The method further includes performing an action based on determining the absence of the input object.

  • Patent number: 9046977
    Abstract: Methods, systems and devices are described for determining positional information for objects using an input device. The various embodiments provide improved user interface functionality by facilitating user input with input objects that are at the surface and objects that are away from the surface. The input device includes a processing system and an array of sensor electrodes adapted to capacitively sense objects in a sensing region. The processing system is configured to determine first positional information for an input object in a first portion of the sensing region based on a difference between a first frame of the first plurality of frames and a filtered frame even when the input object is determined to be in the sensing region when the first plurality of frames are acquired, wherein the filtered frame is based on one or more of the first plurality of frames.
