Abstract: A method of capacitive sensing may include driving a first modulated signal onto a first sensor electrode in an input device and a second modulated signal onto a second sensor electrode in the input device. The method may further include receiving, simultaneously, a first resulting signal from the first sensor electrode and a second resulting signal from the second sensor electrode. The method may further include generating, based at least in part on the first resulting signal and the second resulting signal, a combination signal.

Abstract: The various embodiments described herein provide input devices configured to selectively operate in two different sensing regimes. The first sensing regime is configured to determine positional information for ungloved fingers in the sensing region. The second sensing regime is configured to determine positional information for gloved fingers in the sensing region. The input devices are further configured to switch from operating in the first sensing regime to the second sensing regime responsive to detecting an input gesture that meets each of a set of criteria, where the set of criteria includes a measure of sensor value stability corresponding to the input gesture being beyond a sensor value stability threshold level. So implemented, the input device allows a user to easily switch between two different sensing regimes, and thus can facilitate the use of the device with both gloved and ungloved fingers providing input.

Abstract: In a method of interference avoidance for a capacitive sensor device, a transmitter signal is transmitted with a transmitter electrode of the capacitive sensor device. A resulting signal is received with a receiver electrode of the capacitive sensor device. The resulting signal corresponds to the transmitter signal. A first demodulated output is acquired by demodulating the resulting signal in a first way. A second demodulated output is acquired by demodulating the resulting signal in a second way, where the second way and the first way differ. A shift is made from using the first demodulated output for determining positional information to using the second demodulated output for determining positional information. The shift is based at least in part upon an amount of interference.

Abstract: In a method of operating a touch screen, an object interaction is detected with the touch screen while in a first doze mode. It is determined if a detected object interaction with the touch screen is a valid input object interaction with the touch screen. In response to determining the object interaction is a valid input object interaction, the touch screen is transitioned from the first doze mode to a gesture recognition mode. The touch screen is transitioned from the gesture recognition mode to an active mode in response to a determination of a valid gesture interaction with the touch screen by the input object.

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.

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.
