  • Patent number: 9658722
    Abstract: In a method of capacitive sensing an absolute capacitive sensing signal is driven through at least one of a plurality of routing traces of a printed circuit. Absolute capacitive sensing is performed with at least one sensor electrode of a plurality of sensor electrodes in a sensor electrode pattern. The at least one sensor electrode is coupled with the at least one of the plurality of routing traces. An offsetting signal is transmitted on a parallel conductor overlapping the at least one of the plurality of routing traces, such that charge is offset from the at least one of the plurality of routing traces during the absolute capacitive sensing.

  • Patent number: 9642499
    Abstract: The present invention provides a child bath that can be used either as a stand alone bath or as a conversion unit for conventional bathtubs. The child bath includes a vertical front panel and a horizontal top panel with a wash basin that holds a smaller volume of water than a convention bathtub. A support frame provides structural support to the horizontal and front panels. In one embodiment of the invention, the support frame fits within a conventional bathtub and holds the horizontal panel across the top of the bathtub, while holding the front panel in front of at least a portion of the side of the bathtub. In another embodiment of the invention the support frame holds the horizontal panel higher than the height of a conventional bathtub, thereby allowing an adult to stand next to the tub while bathing a child.

  • Publication number: 20170115779
    Abstract: Embodiments of the invention generally provide an input device with display screens that periodically update (refresh) the screen by selectively driving common electrodes corresponding to pixels in a display line. In general, the input devices drive each electrode until each display line (and each pixel) of a display frame is updated. In addition to updating the display, the input device may perform capacitive sensing using the display screen as a proximity sensing area. To do this, the input device may interleave periods of capacitive sensing between periods of updating the display based on a display frame. For example, the input device may update the first half of display lines of the display screen, pause display updating, perform capacitive sensing, and finish updating the rest of the display lines. Further still, the input device may use common electrodes for both updating the display and performing capacitive sensing.

  • Patent number: 9564894
    Abstract: A processing system for a capacitive input device comprises sensor circuitry and control logic. The sensor circuitry is configured to be communicatively coupled with sensor electrodes of the capacitive input device. The control logic is configured to operate the capacitive input device in a first mode comprising interference sensing at a first level and input object sensing. The control logic is also configured to operate the capacitive input device in a second mode instead of in the first mode in response to: interference measured in the first mode meeting an interference condition; and a determination that input is in a sensing region of the capacitive input device. While operating in the second mode, interference sensing with the capacitive input device is either not performed or else is performed at a second level that is lower in fidelity than the first level.

  • Patent number: 9536072
    Abstract: The disclosure relates to machine-learning behavioral analysis to detect device theft and unauthorized device usage. In particular, during a training phase, an electronic device may generate a local user profile that represents observed user-specific behaviors according to a centroid sequence, wherein the local user profile may be classified into a baseline profile model that represents aggregate behaviors associated with various users over time. Accordingly, during an authentication phase, the electronic device may generate a current user profile model comprising a centroid sequence re-expressing user-specific behaviors observed over an authentication interval, wherein the current user profile model may be compared to plural baseline profile models to identify the baseline profile model closest to the current user profile model.

  • Publication number: 20160224652
    Abstract: The disclosure relates to various distance metrics that may quantify semantic and syntactic relationships between devices. More particularly, a first grammar associated with a first device and a second grammar associated with a second device may each comprise a symbol sequence that re-expresses one or more sequenced data items and one or more rules that represent a repeated pattern in the symbol sequence. Accordingly, one or more distance metrics that quantify a similarity between the first grammar and the second grammar may be calculated according to a comparison between the rules in the first grammar and the rules in the second grammar such that a relationship between the first device and the second device can be determined according to the one or more distance metrics.

  • Publication number: 20160179243
    Abstract: In an example, a processing system for a capacitive sensing device includes a sensor module and a determination module. The sensor module comprises a receiver, coupled to a sensor electrode, configured to receive a capacitive sensing signal. The receiver includes an in-phase channel and a quadrature channel. The in-phase channel is configured to mix the capacitive sensing signal with a local oscillator signal substantially in phase with the capacitive sensing signal. The quadrature channel is configured to mix the capacitive sensing signal with a phase-shifted signal near ninety degrees out of phase with the capacitive sensing signal. The determination module is configured to measure a change in capacitance in response to a demodulated signal of the in-phase channel concurrently with measuring a non-coherent signal in response to a demodulated signal of the quadrature channel.
