    摘要: Methods, systems, and apparatus relate to capacitive touch sensors with a fine-pointed, active stylus. The active stylus is configured to receive a signal from the capacitive touch sensor for synchronizing a time base of the stylus with the capacitive touch sensor. The active stylus is configured to receive a signal from a matrix of the capacitive touch sensor to measure a first position along one axis, and transmit a signal from the single electrode of the stylus to the matrix to indicate a second position of the stylus along another axis of the matrix. The stylus can transmit the received signal to report the first position of the stylus.

    摘要: Techniques for disambiguating touch data and determining user assignment of touch points detected by a touch sensor are described. The techniques leverage both user-specific touch data projected onto axes and non-user-specific touch data captured over a complete area.

    摘要: Architecture for a keyboard that supports the n-key rollover feature, while being compatible with well established, high volume, inexpensive manufacturing techniques. The design is a matrix design that uses resistors at each key rather than diodes, and employs novel circuits which allow any combination of simultaneous key presses to be detected using this resistive matrix. The resistors can be screen printed on the flexible sheets in a manner similar to the conductors. A resistive keyboard matrix employs circuit techniques that eliminate phantom key presses. The resistors can be created by screen-printing carbon ink. Additionally, various implementations of the decoder circuits can be employed to provide the n-key rollover feature on flexible sheets for inexpensive production.

    摘要: A method for displaying or capturing an image comprises directing an illumination beam onto a mirror of a highly resonant, mirror-mount system and applying a drive signal to a transducer to deflect the mirror. In this method, the drive signal has a pulse frequency approaching a resonance frequency of the mirror-mount system. The method further comprises reflecting the illumination beam off the mirror so that the illumination beam scans through an area where the image is to be displayed or captured, and, addressing each pixel of the image in synchronicity with the drive signal to display or capture the image.
