    摘要: Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal. The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.

    摘要: An electronic device includes one or more light sources for emitting light toward a body part of a user and one or more optical sensors for capturing light samples while each light source is turned on and for capturing dark samples while the light source(s) are turned off. A signal produced by the one or more optical sensors is filtered and demodulated produce multiple demodulated signals each associated with a light source. Each signal associated with the light source(s) is analyzed to estimate or determine a physiological parameter of the user.

    摘要: An electronic device has a display and has a touch sensitive bezel surrounding the display. Areas on the bezel are designated for controls used to operate the electronic device. Visual guides corresponding to the controls are displayed on the display adjacent the areas of the bezel designated for the controls. Touch data is generated by the bezel when a user touches an area of the bezel. The device determines which of the controls has been selected based on which designated area is associated with the touch data from the bezel. The device then initiates the determined control. The device can have a sensor for determining the orientation of the device. Based on the orientation, the device can alter the areas designated on the bezel for the controls and can alter the location of the visual guides for the display so that they match the altered areas on the bezel.

    摘要: Ultrasonic ranging for mobile devices is disclosed. A mobile device using ultrasonic ranging can include an ultrasound transmitter capable of emitting an ultrasound signal for detection by a proximate device and an ultrasound receiver capable of receiving an ultrasound signal from the proximate device. The mobile device can then use a time lapse associated with one or both of these ultrasound signals to find a range to the proximate device.

    摘要: Input members with capacitive sensors are disclosed. In one embodiment of an electronic button, a first circuit is configured to capture a fingerprint of a user's finger placed on the electronic button, and a second circuit is configured to sense a force applied to the electronic button by the user's finger. The first circuit is further configured to provide temperature information to compensate for temperature sensitivities of the second circuit, and the second circuit is further configured to provide force information to the first circuit.
