摘要： A tongs monitor for monitoring the tightening of tubing, casings, and sucker rods of a well is selectively operable in a learning mode and a monitoring mode. A target tightness value is determined during the learning mode. Subsequent tightness values are then compared to the target value. For example, a first connection is tightened in a conventional manner, while its tightness is monitored during the learning mode. If the tightening process went well, then an operator pushes a button that tells the monitor to remember how tight the first connection was tightened. The tightness value of that first joint then becomes the target tightness value for any subsequent joints. As additional joints are tightened, their tightness are monitored and compared to the first one to ensure that all the joints are as good as the first one within an allowable tolerance.

摘要： An apparatus and method for assisting cardiac function of a patient includes a flaccid inflatable chamber held at a predetermined volume generally midway between fully inflated and fully deflated for performing a periodically scheduled patient monitoring routine for measuring values of the physiology of the patient, and reinflating the chamber after either detecting a dicrotic notch or expiration of a measurement time period window, whichever occurs first. A software program is connectible in electronic communication with the control program for adjusting settings of the drive unit. The software program is capable of one or more of the following functions: retrieving current values of physician programmable parameters, selectively retrieving a history of the drive unit operation including error detection records, displaying a continuous ECG, and/or displaying a single-beat sample of aortic pressure waveform obtained in real time from the patient.

摘要： In accordance with the present invention, an apparatus and a method for regulating exhaust pressure in an evacuation system of a semiconductor process chamber are provided. The method comprises steps of generating a first pressure in the semiconductor process chamber with the evacuation system, monitoring the first pressure to generate a first signal, determining a set point for the exhaust pressure responsive to the first signal, and regulating the exhaust pressure by a controller till reaching the set point. The key aspect of the present invention is to maintain the equilibrium of the chamber pressure and the exhaust pressure by implementing an exhaust controller to control the gas flow rate introduced into the evacuation system. In other words, when the chamber pressure is increased, the gas is introduced into the evacuation system at an increased flow rate. On the other hand, when the chamber pressure is decreased, the gas is introduced into the evacuation system at a decreased flow rate. The dynamic control over the gas introduced into the evacuation system advantageously increase the speed of response during the changes of chamber pressure, as well as active control of the chamber pressure in place of moving the throttle valve. Thus, by minimizing the movement of throttle valve, the chances of particulate contamination of the process are greatly reduced.

摘要： A low-mass pointer element for a pressure measuring mechanism is made from a lightweight plastic paper material and includes a center hub having a through aperture which is sized to accommodate a rotatable shaft end of the pressure measuring mechanism. An indicating end of the pointer element is sloped downwardly toward a dial face relative to the center hub to prevent parallax along with a counterbalancing portion. The indicating end is inwardly tapered to a flattened distal end to provide equivalent stiffness, but with considerably less mass so as to significantly reduce stress loads on a corresponding movement mechanism.

摘要： A semiconductor pressure sensor chip is housed in a pressure detecting chamber, and a pressure port is provided which causes the pressure detecting chamber and a space in which pressure is to be measured are in communication with each other. A protective portion is provided inside the pressure port in such a manner as to substantially close an inlet of the pressure detecting chamber in the state in which the pressure detecting chamber and the space in which pressure is to be measured are in communication with each other. This prevents degraded and solidified foreign matter such as oil and gasoline, which are led into the pressure port from the space in which pressure is to be measured, from entering the pressure detecting chamber and colliding with the sensor element and the like.

摘要： A method for obtaining the average ambient air pressure outside of a building places a pressure sensor on each major outside wall of the building or around the outer circumference of a one sided (e.g., round) building. The pressure reading from each pressure sensor is obtained and the pressure readings are added together to obtain a total reading. The total reading is divided by the number of pressure readings making up the total, the result being the approximate average ambient air pressure outside of the building.
