    摘要: In an electrostatic driving structure for a MEMS device or other electrostatically-driven device, non-insulating material is disposed on or adjacent a gap on the surface of a dielectric between adjacent electrodes and is electrically coupled to a source of potential, so as to form an electrostatic shield which reduces the effect of mobile charges in the dielectric gap on the forces generated by the electrostatic driving structure. The shield is made of non-insulating material and may, for example, be formed by plating of metal or epitaxial deposition of silicon onto the electrode.

    摘要: A resonator device utilizes two small mechanical resonators that are electrostatically coupled. A first resonator receives an input signal near its resonant frequency, and the input signal and a second signal are summed and provided to a second resonator. The resonant frequency of the second resonator is approximately equal to the second signal frequency. A width of response of the amplifier is tuned by varying the pump voltage. Resonant frequencies of corresponding individual oscillators are tuned by adjusting bias voltages.

    摘要: Cellular signals or other wireless signals/messages are introduced into a building or to an outside location by transmitting packets corresponding to those signals over a data network and low cost cables to designated locations within the data network. Once the designated packets containing the signals reach the destination, they are then broadcast over the air to a terminal capable of receiving the wireless message. In a first embodiment, an in-building gigabit Ethernet network, such as that currently existing presently in many buildings, is used to distribute radio signals indoors. Instead of transmitting the radio signals over the air from a repeater connected to a base station, coded baseband signals generated by the coding processor (e.g., a CDMA Modem Unit) in the base station are packetized and sent over the Ethernet network to radio processing equipment and antennas distributed throughout the building. The radio processing equipment strips the packet headers from the baseband signal packets so those signals can be broadcast via the antennas to one or more mobile terminals.

    摘要: An integrated piezo-resistive sensor for determining mirror position in an optical switch. One or more piezo-resistive layers may be formed in silicon springs supporting a movable mirror in the switch. Change in resistivity of those layers due to spring deformation during mirror motion is measured and related to the mirror deflection angle. Information about the angle may be used to provide feedback to the motion actuator, which then may be operated to orient the mirror more accurately. A sensor's sensitivity may be increased by appropriately orienting the springs with respect to the crystallographic axes of the silicon.

    摘要: A micro-electrical mechanical oscillator has a resonant frequency of oscillation that is varied by application of heat. The resonant frequency is varied at a frequency different from the resonant frequency of the oscillator to amplify oscillations. In one embodiment, the oscillator is disc of material supported by a pillar of much smaller diameter than the disc. The periphery of the disc is heated by a laser to provide a time varying shift of the resonant frequency (or equivalently the stiffness) of the disc. Feedback from movement of the disc is used to modulate the intensity of the laser, and thus the stiffness of the disc to provide parametric amplification of sensed vibrations, using heating as a pump. Various other shapes of micro-electrical mechanical oscillators are used in other embodiment, including an array of such oscillators on a substrate, each having different resonant frequencies.
