Abstract: A vector network analyzer using sliding correlator techniques and multi-user detection techniques. The sliding correlator technique is based on the time domain sliding effect caused by a small clock frequency offset in the pseudo random code generators of a transmitter and a receiver. A time scaled version of the impulse response of the device under test can be obtained from the time domain slided pseudo random code signals by using a correlator. A multi-user detection method is introduced using two uncorrelated pseudo random codes. One of the uncorrelated pseudo random codes measures the D.U.T. and another code is a reference channel. These codes can be demodulated and despread with one receiver module. A Fast Fourier Transform of the measured impulse response is the frequency response of the measured signal.

Abstract: In the measurement of the surface of a wafer mounted on a mounting device, a method of removing the errors induced by the mounting device from the measurement data. The method includes the steps of 1) measuring a plurality of points on the surface to obtain a first matrix which contains the device induced errors and the proper surface of the object; 2) rotating the object independently of the mounting device; 3) measuring the rotated object to obtain a second matrix which contains the device induced errors and the proper surface of the object as transformed by a rotation matrix; 4) obtaining the difference of the second matrix and the first matrix thereby eliminating the device induced error; and 5) applying the inverses of LU matrices on the difference of the rotation matrix and an identity matrix to obtain the proper surface. In step 5, the process involves flipping the wafer and measuring the surface as flipped.

Abstract: A method and device for controlling a self-regulating, delayed process, in particular a temperature control system, in which, after a first setpoint step change, the manipulated variable is set to its maximum value and an IT1 model of the process is identified on the basis of the step response. The time at which the manipulated variable must be reset for time-optimum control is calculated on the basis of this model. An additional, more precise model is determined if the rate of change of the controlled variable drops below a specific limit after the shut-off time. The parameters of a linear controller are set as a function of the more precise model, after which the controller controls the process in a non-linear mode. When additional setpoint step changes occur, a time for switching to a steady-state manipulated variable is calculated on the basis of the more precise model in order to achieve time-optimal control.

Abstract: A method for operating a pump controller to pressurize a liquid product line for thermal stabilization during a leak test is accomplished as follows. A microprocessor controlled timer is installed in a petroleum service station product dispensing system that includes a pump relay, a pump, a dispenser, and a leak detection monitor. The timer activates pump relays to pressurize a liquid product line that runs from a tank to the dispenser at predetermined intervals to compensate for thermal contraction during product line leakage testing. Prior to activating pump relays, the timer has circuitry and program determines if product is currently being dispensed. If product is being dispensed, the timer waits until dispensing has halted then starts a timer to provide a delay before activating pump relays to pressurize the product line. Also prior to activating pump relays, the timer has circuitry and program determines if pump operation should be inhibited and if so halts before activating pump relays.

Abstract: A method for accurately determining the formation pressure of earth formans. Formation measurements are made with by use of a novel downhole tool which allows drilling mud to enter the tool in such a way that decompression of drilling mud is controlled so that the pressure in the borehole is allowed to fall only slightly below the formation pressure. The drawdown of mud into the tool is then stopped and the pressure is allowed to stabilize at the formation pressure. The measurement is completed in a matter of a few minutes as opposed to hours, or even days, as required by more conventional techniques.
