  • Publication number: 20140267070
    Abstract: A touch input device configured to detect stylus signals generated by an external stylus is provided. The touch input device includes a plurality of stylus signal detectors that receive at its input a combination of stylus receive channels that are combined in a manner to minimize noise while at the same time keeping the stylus signal strength uniform independent of the position of the stylus on the device.

  • Publication number: 20140152582
    Abstract: A touch sensitive device capable of detecting signals generated by a stylus and correcting the detected stylus signals for effects due to noise present on the device is disclosed. In one example, signals are taken from one or more electrodes that are a pre-determined distance away from an electrode in which a stylus signal is detected. The pre-determined distance can be empirically determined such that a noise estimate can be generated such that the electrodes have a higher probability of containing only noise that is highly correlated to the noise present on a detected stylus signal. The generated noise estimate is then subtracted from a detected stylus signal to reduce the effect of noise on the stylus signal.

  • Patent number: 7824098
    Abstract: Mechanical transducers such as pressure sensors, resonators or other frequency-reference devices are implemented under conditions characterized by different temperatures. According to an example embodiment of the present invention, a combination of materials is implemented for mechanical transducer applications to mitigate temperature-related changes at or near a selected turnover temperature. In one application, a material property mismatch is used to facilitate single-anchor transducer applications, such as for resonators. Another application is directed to a Silicon-Silicon dioxide combination of materials.

  • Patent number: 6055203
    Abstract: A row decoder for controlling a plurality of selectable word-lines has one control line per block of N word-lines, K select lines, at least one disable line and one word-line driver per word-line. Each control line is activatable during a charge period and during an initial portion of a discharge period. Each select line is selectably high during the charge period. The disable line is active during the discharge period. Each driver includes an access transistor and a discharge transistor. The access transistor is located at one end of its word-line and the discharge transistor is connected at the other end. The access transistor is controlled by one control line and is connected between one select line and the word-line. The discharge transistor is controlled by one disable signal and is connected between the word-line and a ground supply.
