    • The present invention relates to a method for adjusting the resonant frequencies of a vibrating microelectromechanical (MEMS) device. In one embodiment, the present invention is a method for adjusting the resonant frequencies of a vibrating mass including the steps of patterning a surface of a device layer of the vibrating mass with a mask, etching the vibrating mass to define a structure of the vibrating mass, determining a first set of resonant frequencies of the vibrating mass, determining a mass removal amount of the vibrating mass and a mass removal location of the vibrating mass to obtain a second set of resonant frequencies of the vibrating mass, removing the mask at the mass removal location, and etching the vibrating mass to remove the mass removal amount of the vibrating mass at the mass removal location of the vibrating mass.

    • Provided is a chip-scale atomic clock having a folded optic configuration or physics package. In particular, the physics package includes a vapor cell for containing gaseous alkali atoms and a VCSEL for generating a laser light One or more heating elements are positioned to simultaneously heat both the vapor cell and VCSEL to the required operating temperature. A micro-lens element, positioned between the VCSEL and a reflector, is used to first expand the beam of light, and then to subsequently collimate the light after it is once reflected. Collimated, reflected light passes through the vapor cell wherein the alkali atoms are excited and a percentage of the reflected light is absorbed. A detector, located opposite the reflector and micro-lens array, detects light passing through the cell. An error signal is generated and the output voltage of a local voltage oscillator is successively stabilized.
    • 提供了具有折叠光学配置或物理封装的芯片级原子钟。 特别地,物理包装包括用于容纳气态碱性原子的蒸汽池和用于产生激光的VCSEL。一个或多个加热元件被定位成同时将蒸汽单元和VCSEL两者加热到所需的工作温度。 位于VCSEL和反射器之间的微透镜元件用于首先使光束膨胀,然后在稍后反射之后对光进行准直。 准直的反射光通过蒸汽池,其中碱性原子被激发并且反射光的百分比被吸收。 与反射镜和微透镜阵列相对的检测器检测通过电池的光。 产生误差信号,本地电压振荡器的输出电压相继稳定。

    • A microelectromechanical (MEM) fluid health sensing device comprises a viscosity sensor which provides an output that varies with the viscosity of a fluid in which it is immersed, and at least one other sensor which provides an output that varies with another predetermined parameter of the fluid. The viscosity sensor is preferably a MEM device fabricated by means of a “deep etch” process. The sensors are preferably integrated together on a common substrate, though they might also be fabricated separately and packaged together to form a hybrid device. A data processing means may be included which receives the sensor outputs and provides one or more outputs indicative of the health of the fluid. Sensor types which may be part of the present device include, for example, a temperature sensor, a MEM electrochemical sensor, a MEM accelerometer, a MEM contact switch lubricity sensor, and/or an inductive metallic wear sensor.
