Abstract: A method exploits the spectral signature of cloud bases in microwave moisture sounder data to determine cloud base heights. This signature requires the accurate specification of cloud top height, which in a preferred embodiment, comes from the analysis of data provided by an electro-optical sensor (EO) such as the Advanced Very High Resolution Radiometer (AVHRR) instrument flown on operational NOAA satellites. The method includes a receiving step in which satellite EO (visible through infrared) and microwave radiance data of a view of the earth's atmosphere is received. The view has both location and time information. In a determining step, cloud top height is determined based on the EO and infrared radiance data. Moisture profiles of the view are retrieved in a retrieving step based on the microwave radiance data. Subsequently, in a determining step, cloud base heights of clouds in the view are determined using cloud top heights as a constraint in the retrieval of moisture profiles with tile microwave data.

Abstract: A high sensitivity, Z-axis capacitive microaccelerometer having stiff sense/feedback electrodes and a method of its manufacture are provided. The microaccelerometer is manufactured out of a single silicon wafer and has a silicon-wafer-thick proofmass, small and controllable damping, large capacitance variation and can be operated in a force-rebalanced control loop. The multiple stiffened electrodes have embedded therein damping holes to facilitate both force-rebalanced operation of the device and controlling of the damping factor. Using the whole silicon wafer to form the thick large proofmass and using the thin sacrificial layer to form a narrow uniform capacitor air gap over a large area provide large capacitance sensitivity. The structure of the microaccelerometer is symmetric and thus results in low cross-axis sensitivity. In one embodiment, because of its all-silicon structure, the accelerometer exhibits very low temperature sensitivity and good long term stability.

Abstract: A pipe (P) carries corrosive fluids (F). Ultrasonic measurements of the pipe's thickness are made with an instrument (10) to determine if it needs to be replaced. If the pipe is coated with a layer (L) of protective material (C), a time of flight (TOF) measurement is made to determine the velocity of ultrasonic pulses transmitted through the material from which the pipe is manufactured. A second measurement is made to determine the velocity of pulses through the coated pipe material. The pulse velocity is now a function of the coating thickness by knowing the two velocity values, the coating thickness is determined. An ultrasonic pulse measurement of the thickness of the coated pipe is then made. The coating thickness is then calculated by a processor (12) of the instrument. If the thickness value is less than a minimum thickness value (M), an indication is given that the pipe needs to be replaced.

To perform such a process rapidly and thus economically, the influencing factor is continuously changed and the current output value of the sensor and the current measurement provided by the measuring device are detected with a timing predetermined by the data processing system.

Abstract: An extension bar that has a cylindrical hollow shaft that has two solid ends for use with socket type wrenches. At one end, a solid piece of metal is machined to a post to receive the socket. At the other end, the solid member has a recess formed in it to receive the post of the socket wrench. Unlike the extension bars available today, the recess for the socket wrench does not penetrate into the hollow shaft. This construction, unlike the others, prevents the extension from twisting when torque is applied by the wrench. Instead of having to overcome the twisting force before torque is applied to a fastener, the torque is transmitted directly to the fastener. This type of extension bar can be made in any length, even three or four feet. Even at those lengths, the extension does not twist. As a result, repair operations are faster and safer.
