摘要： An AC-to-DC adapter may be provided in order to increase the sensitivity of a touch-sensitive surface. Such an AC-to-DC adapter may include a rectifying circuit to rectify incoming AC signals. The rectifying circuit may take the form of a diode bridge network that includes four diode branches. Stabilization circuits may be provided in parallel with each diode branch in order to decrease the impedance of the diode bridge network during particular periods of operation. The stabilization circuits may be configured such that the impedance of the diode bridge network is substantially constant during all periods of operation. As a result, the impedance of the AC-to-DC adapter may be relatively constant during all periods of operation. In turn, the sensitivity of a touch-sensitive surface of a device being powered by such an AC-to-DC adapter may increase.

摘要： Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

摘要： A synchronous signal processing circuit for a dual-axis vibratory rotation-rate sensor uses a hybrid analog/digital design to provide correction for parasitic quadrature errors by the addition of synthesized correction signals in the analog domain prior to digitization. Error correction, signal demodulation and data conversions are synchronized with a signal phase-locked to the measured motion of the vibratory mass. Similarly, cross-axis error correction signals are synthesized directly from the cross axis signals. Use of these precise phase references provides for various benefits in signal noise and error matching (tracking) over wide operation conditions.

摘要： A vibratory rotational rate gyroscope has a suspended assembly isolated from external vibrations by an arrangement of helical springs. This isolated assembly includes both the active components of the rotational rate gyroscope and a digital processing circuit. The digital processing circuit includes digital storage for both externally determined and internally determined unit-specific calibration values. These values provide seed values for startup processes, which improves loop startup time, and values for unit-specific electronic calibration. The digital processing circuit further converts all data to digital form. A digital communications protocol is used to transmit the calibration information and the outgoing data to and from the isolated assembly on only two conductors. Two additional conductors used for power. Four of the helical springs used in the suspension arrangement are used for these conductors such that no additional wiring is required.

摘要： A dual-axis rotational rate sensor having two vibratory masses coupled to a restoring element and driven in a resonant counter-phase motion, wherein the two masses vibrate with equal but opposite amplitudes along a single axis. The vibratory structure also accommodates motion of the masses in a plane orthogonal to the vibratory axis. Measurement of the motion of the masses in two axes in this plane provides signals directly responsive to rotation of the sensor about two orthogonal axes. Measurement and drive is facilitated by the use of magnetic masses and electromagnetic drive and sense transducers.
