    摘要: The electrical equivalent of a relatively large area proximity detection capability is provided in a space limited electronic device (20, 30) with many individual input electrodes (24, 34, 44) by dynamically coupling parallel groups of the individual electrodes (24, 34, 44) and applying a proximity and/or contact test thereto. The parallel grouped electrodes act like a single large electrode and permit proximity detection at greater distances and with greater sensitivity. A multiplexer (74) automatically couples individual input electrodes (23, 24, 44) and then parallel grouped electrodes to the proximity (or contact) sensor(s) (46, 66), so that they are scanned and sensed individually and collectively in a time less than human reaction time, whereby the proximity sense function appears as if provided by a separate large area electrode. Proximity spatial detection accuracy is increased by using some of the electrodes (24, 34, 44) as driven shields to remove positional ambiguity.

    摘要: Embodiments include methods and apparatus for performing capacitive touch sensing and proximity detection. Electrode selection circuitry establishes a first connection with an individual electrode of a plurality of individual electrodes in order to receive one or more first signals indicating a state of the individual electrode, and establishes second connections with a proximity electrode that comprises multiple ones of the plurality of individual electrodes in order to receive one or more second signals indicating a state of the proximity electrode. A processing system performs a first analysis on the first signals to determine whether to perform a first updating process for an individual electrode baseline value, and performs a second analysis on the second signals to determine whether to perform a second updating process for a proximity electrode baseline value. In an embodiment, the first analysis and the second analysis are different from each other.

    摘要: Embodiments include capacitive touch sensors and methods for configuring capacitive touch sensors. A capacitive touch sensor embodiment includes an analog-to-digital converter (ADC) and a controller. The ADC receives an analog voltage signal from an electrode, and samples the analog voltage signal to produce a plurality of digital values. The controller performs a first charging process by supplying the electrode with a first charging current for a first charging interval, and the controller determines, based on the digital values, whether a first electrode voltage value meets a criteria. If not, the controller performs a configuration process that results in setting a second charging current and a second charging interval for the electrode which, in response to performing a second charging process, results in a second electrode voltage value that meets the criteria.

    摘要: A system that holds a liquid such as water includes an electrode coupling the system to a surface. A capacitance sensor is coupled to the electrode. A processor is coupled to the capacitance sensor. The processor is adapted to receive a signal from the capacitance sensor to determine whether the liquid is present at the surface and to send one or more indication signals if liquid is present at the surface. A response circuit coupled to the processor causes the system to take responsive action in response to receipt of an indication signal. Responsive action includes causing the system to perform a failsafe action, such as automatic shutdown. A communication circuit notifies a user that a fault has occurred in the system over a network.

    摘要: A capacitive touch pad includes an electrode board, a plurality of capacitive touch sensor pads, and a cover. The electrode board has touch sensor circuitry formed thereon. The plurality of capacitive touch sensor pads is formed in an array over the touch pad circuitry of the printed circuit board. The plurality of capacitive touch sensor pads is spaced apart by a predetermined distance to form spaces between the pads of the plurality of capacitive touch sensor pads. The cover is positioned over and covering substantially all of the plurality of capacitive touch sensor pads. The cover has a first cavity with a first depth, where the first cavity is shaped to form an air gap between the pads of the plurality of capacitive touch sensor pads to dampen capacitive coupling between adjacent touch pads.
