Abstract: Characterizing an exposure tool involves receiving data describing a pattern formed at a wafer. The pattern is formed by illuminating the wafer using an exposure tool, and the data has a scan direction and slit direction. An image field is mapped according to the data to determine an image field error of the data, and the image field error is separated from the data to reduce variation of the data in the scan direction. The data is reduced to the slit direction. Errors associated with the exposure tool are determined from the data in order to characterize the exposure tool.

Abstract: In a thermal-type airflow meter that measures an intake airflow rate in an internal combustion engine of an automobile or the like, there has been a problem that pulsation errors caused by external fluctuations under the environment including a large pulsation and reverse flow in the intake valve are difficult to be reduced. In order to solve this problem, the invention provides a flowmeter comprising a detection element that outputs a non-linear signal corresponding to a flow rate, and a regulation means that regulates an output signal of the detection element for controlling. With this construction, the regulation means executes output regulation processing that regulates irregularities of the detection element in the output signal, and inequality linearization processing that regulates an average value of the output signal after the output regulation processing by means of regulating parameters.

Abstract: Flow meter electronics are described for providing a flow rate of a material flowing through a flow meter sensor of a Coriolis flow meter. The flow meter electronics comprise a processing system and a single output port. The processing system receives pick-off signals from the flow meter sensor and processes the pick-off signals to determine the flow rate. The processing system receives an instruction for a frequency output signal or a digital communication protocol signal. If the instruction is for a frequency output signal, then the processing system processes the flow rate to generate a frequency output signal and transmits the frequency output signal over the single output port. If the instruction is for a digital communication protocol signal, then the processing system processes the flow rate to generate a digital communication protocol signal and transmits the digital communication protocol signal over the single output port.

Abstract: The invention relates to a new method for determination of realistic UV protection factors or bread spectrum indices of a sunscreen preparation. Realistic UV protection factors are calculable by determination of the theoretical and the experimental UV absorbances of known UV filters in wavelength steps of about 5 nm in the range of 290-400 nm from a definite basic formulation (emulsion, gel etc.) and on a transparent substrate and introducing of the values in a mathematical model. These factors are in conformity with values measured in vivo. The number of the experiments for developing new formulations are significant reduced because only basic formulation, kind and concentration of the filters have to enter.

Abstract: A system and method for estimating an operating parameter of a vehicle such as the steering angle offset or body slip angle. The method includes providing a dynamic vehicle model which is valid when the yaw rate and slip angle of the vehicle are either constant or changing. The vehicle model is reformulated to allow for the direct estimation of the steering angle offset value and/or the body slip angle. Estimation of an operating parameter of the vehicle may also include the use of a model difference term which is defined by the difference between a value estimated using the model and a measured value. A method for filtering the steering angle offset value is also provided. The filtering method may utilize a variable filter coefficient which varies in response to changes in the dynamic behavior of the vehicle.

Abstract: A method and apparatus for a compiler, or similar computer language translating device, to translate a computer language into a sequence of electronic instructions to be executed at run-time by at least one functional unit in a computer. At compile time, the compiler creates and analyzes the sequential order of the electronic instructions to determine exact moments when the functional unit will begin to, or complete, executing the electronic instructions. Consequently, the compiler can predict time intervals when the functional unit will be in use, or idling between instructions. In addition, the compiler knows the delay time, or latency, involved in powering up and powering down the functional unit. The compiler compares the use times, or idle times, to the latency, and creates power-controlling instructions to be embedded into the sequence of electronic instructions. The power-controlling instructions are to control power to the functional units at run-time.

Abstract: In improvements to the Fluid Energy Pulse Test System, apparatus and methods regulate high-pressure, high-fluid-flow-rate energy pulses to generate temperature-controlled transient, ramp, constant-steady-state, and periodic-steady-state fluid-pressure and fluid-flow-rate test data and sound data for evaluating fluid control devices. Transient, ramp, and constant-steady-state performance curves describe dynamic operating characteristics of tested devices. Transient and constant-steady-state pressures and flow rates are precisely defined and compared. Constant fluid conductance is represented by transverse lines on performance graphs. Constant- and periodic-steady-state pressures and flow rates are achieved in less than two seconds. Temperature sensitivity of fluid control devices is determined. Fluid-pressure and fluid-flow-rate data correlated with sound data create audio-visual representations. Three-dimensional amplitude-frequency-time sound signatures are displayed graphically.

Abstract: A TL1 usage model generator arranged to provide a statistically accurate usage model based upon a particular user profile is described. The TL1 usage model generator is connected to a translator arranged to expand the usage model provided the by TL1 usage model generator into a fully meshed file. Coupled to the translator, a TL1 sequence generator uses the fully meshed file to automatically generate a random sequence of TL1 commands that is provided to an execution engine configured to read the random sequence of TL1 commands. The execution engine, in turn, sends the random sequence of TL1 commands to the system under test (SUT) the results of which are forwarded to and written in a result data base used by a post processor to verify the validity of the system response.

Abstract: A circuit is arranged to pulse-width modulate the duty cycle of a power supply signal that is used to control the rotational speed of a fan in a temperature-controlled system. The control system includes an edge detector for monitoring a tachometer signal that is provided by the fan. The tachometer signal is monitored at a rate (e.g., one Hertz) that is substantially lower than the rotational speed of the fan. The control system also includes a timer for recording time intervals between selected edges of a monitored tachometer signal. The fan speed is determined from the recorded time intervals. The control system extends the duty cycle of the pulse-width modulated signal to ensure that the fan power remains stable over the period in which the tachometer signal is to be monitored. Maintaining fan power ensures the validity of the tachometer signal during the period that the fan power is maintained.

Abstract: A diagnostic system for an HVAC system includes a number of sensors used to measure the operation of the HVAC system. Sensor readings are measured by timing the delay between when a strobe signal is sent to a sensor and when an interrupt signal from the sensor is received. A device driver used to measure the sensor readings stores the sensor readings in pseudo-character device files, which are universally accessible by different subsystems of the diagnostic system. Based on the readings from these sensors, this diagnostic system is able to determine the operational status of the HVAC system and if an economizer in the HVAC system is operating properly.

The multipath detector is capable of applying a dynamic threshold against the measurement noise variance estimate to determine whether a multipath condition exists. And, the multipath bias estimator is capable of generating a correction for multipath induced measurement bias error from a measurement noise variance estimate for application upon determining that a multipath condition exists.
