  • Publication number: 20200110920
    Abstract: An apparatus comprises a fingerprint sensor having a set of capacitive elements configured for capacitively coupling to a user fingerprint. The fingerprint sensor may be disposed under a control button or display element of an electronic device, for example one or more of a control button and a display component. A responsive element is responsive to proximity of the user fingerprint, for example one or both of a first circuit responsive to motion of the control button, and a second circuit responsive to a coupling between the fingerprint and a surface of the display element. The fingerprint sensor is disposed closer to the fingerprint than the responsive element. The control button or display component may include an anisotropic dielectric material, for example sapphire.

  • Publication number: 20200042509
    Abstract: A system has data capture devices collecting data from different points in a network. The captured data is written to a data store and is directed to an output. The data from the different data capture devices can be delivered to a data analytics device. As long as the data analytics device is able to keep pace with the data that is directed to the output, that data is used by the analytics device. If the analytics device is not able to keep pace, the data written to the data store is retrieved and is used until the analytics device has caught up.
