Abstract: According to one embodiment, a sensor device includes a sensor, a control unit configured to cause the sensor to perform sensing and receive a signal from the sensor, and a processor configured to determine presence or absence of a sensing and obtain biometric information of the sensing target. The control unit is configured to cause the sensor to perform first sensing and cause the sensor to perform second sensing when the processor determines the presence of the sensing target during the first sensing. Power consumption during the first sensing is less than power consumption during the second sensing.

Abstract: A method of training a fingerprint image enhancing engine for use in a fingerprint capturing device, and a corresponding apparatus and computer readable medium, include producing a synthetic image dataset comprising plural pairs of synthetic images. Each pair of synthetic images include a clean synthetic image and a raw synthetic image corresponding to the clean synthetic image. Each raw synthetic image is produced according to a model of the fingerprint capturing device. The method also includes training a neural network using the synthetic image dataset.

Abstract: Certain aspects of the present disclosure generally relate to a touch panel. The touch panel may include a cover layer, of a plurality of layers, configured to receive a touch force applied to the touch panel. The touch panel may include a force determination set of layers, of the plurality of layers, to determine a magnitude of the touch force applied to the touch panel. The force determination set of layers may include a piezoelectric layer with a set of force determination pixels. The set of force determination pixels may be arranged in a matrix to address the set of force determination pixels. A force determination pixel may be configured to generate a charge for determining a location of the touch force applied to the touch panel and a magnitude of the touch force applied to the touch panel.
