| 20080236280 | FORCE REBALANCING AND PARAMETRIC AMPLIFICATION OF MEMS INERTIAL SENSORS - MEMS devices and methods for measuring Coriolis forces using force rebalancing and parametric gain amplification techniques are disclosed. A MEMS inertial sensor can include one or more proof masses, at least one sense electrode positioned adjacent to each proof mass, a number of torquer electrodes for electrostatically nulling quadrature and Coriolis-related proof mass motion, and a number of pump electrodes for producing a pumping force on the proof masses. Force rebalancing voltages can be applied to some torquer electrodes to electrostatically null quadrature and/or Coriolis-related proof mass motion along a sense axis of the device. A pumping voltage at approximately twice the motor drive frequency of the proof masses can be used to pump the proof masses along the sense axis. | 10-02-2008 |
| 20080290114 | Drug Delivery Flow Controller - A drug delivery system for delivering a fluid to a desired location within a body that uses two control loops to control fluid flow: a first control loop in which a pressure source moves the fluid at an approximate rate, and a second control loop where a variable impedance mechanism more precisely controls the flow rate. After the fluid has moved through the chambers of these two control loops, a flow sensor measures the flow rate, sends the flow rate information to the control electronics, which then adjusts the pressure and impedance in a closed-loop manner to maintain a constant, desired flow rate. The drug delivery device may be used in portable or wearable mechanisms. | 11-27-2008 |
