摘要： A toxic gas sensor or device which is a cavity ring-down spectroscopy device having two or more mirror components. Each of the mirror components has two Brewster windows attached to it. The Brewster windows are resistant to toxic gases and together with the respective mirror form a hermetically sealed volume for the mirror surface to protect it from the environment or test gases. The Brewster windows may have a heating mechanism to remove contaminants, condensation, and provide temperature stabilization and other beneficial features.

摘要： A method of bonding and packaging components of Micro-Electro-Mechanical Systems (MEMS) and MEMS based devices using a Solid-Liquid InterDiffusion (SLID) process is provided. A micro-machine is bonded to a micro-machine chip using bonding materials. A layer of chromium is first deposited onto surfaces of the micro-machine and the micro-machine chip followed by a layer of gold. Subsequently, a layer of indium is deposited between the layers of gold, and the surface of the micro-machine is pressed against the surface of the micro-machine chip forming a gold-indium alloy to serve as a bond between the micro-machine and the micro-machine chip. In addition, a cover is bonded to the micro-machine chip in the same manner providing a hermetic seal for the MEMS based device.

摘要： By applying a first value of voltage to a first side of a MEMS gyroscope and applying a second value of voltage to a second side of the MEMS gyroscope, the start time of the MEMS gyroscope may be improved. The first and second value of voltage may be provided by a bias power source, such as a battery or a super capacitor. The first value of voltage may be substantially equal in magnitude to and opposite in polarity to the second value of voltage. The bias power source may also be applied to drive electronics connected to the MEMS gyroscope. The bias power source may prevent amplifiers within the drive electronics from saturating during the start time.

The support member can be attached to the substrate at the substrate attachment surface and the sensor can be attached to the support member at the sensor attachment surface. The sensor mount is shaped so an oblique angle is formed between the plane that includes the substrate attachment surface and the plane that includes the sensor attachment surfaces. Preferably, the support member has a wedge shape.

摘要： A system and method for deriving an angular rate includes receiving a motor pick off signal received from a motor pick off of from a MEMS gyroscope. Receiving a sensing pick off signal received from a sensing pick off from the MEMS gyroscope allows the determining of a phase relationship between the motor pick off signal and the sensing pick off signal. Determining an angular rate is based upon an amplitude of the sensing pick off signal. Determining the whether the sign of the rotational rate is positive or negative is based upon the phase relationship of the sensing pick off signal from a MEMS gyroscope relative to the motor pick off signal received from the motor pick off.
